Instructions for Authors<br />

Instructions for authors are published in the journal and at www.<br />

tjh.com.tr<br />

Material Disclaimer<br />

Authors are responsible for the manuscripts they publish in The<br />

<strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong>. The editor, editorial board, and<br />

publisher do not accept any responsibility for published manuscripts.<br />

The journal is printed on acid-free paper.<br />

Editorial Policy<br />

Following receipt <strong>of</strong> each manuscript, a checklist is completed by<br />

the Editorial Assistant. The Editorial Assistant checks that each<br />

manuscript contains all required components and adheres to the<br />

author guidelines, after which time it will be forwarded to the Editor<br />

in Chief. Following the Editor in Chief’s evaluation, each manuscript<br />

is forwarded to the Associate Editor, who in turn assigns reviewers.<br />

Generally, all manuscripts will be reviewed by at least three reviewers<br />

selected by the Associate Editor, based on their relevant expertise.<br />

Associate editor could be assigned as a reviewer along with the<br />

reviewers. After the reviewing process, all manuscripts are evaluated<br />

in the Editorial Board Meeting.<br />

<strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong>’s editor and Editorial Board<br />

members are active researchers. It is possible that they would desire<br />

to submit their manuscript to the <strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong>.<br />

This may be creating a conflict <strong>of</strong> interest. These manuscripts will<br />

not be evaluated by the submitting editor(s). The review process<br />

will be managed and decisions made by editor-in-chief who will act<br />

independently. In some situation, this process will be overseen by an<br />

outside independent expert in reviewing submissions from editors.<br />

TURKISH JOURNAL OF HEMATOLOGY<br />

INSTRUCTIONS TO AUTHORS<br />

The <strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong> accepts invited review articles,<br />

research articles, brief reports, case reports, letters to the editor, and<br />

hematological images that are relevant to the scope <strong>of</strong> hematology,<br />

on the condition that they have not been previously published<br />

elsewhere. Basic science manuscripts, such as randomized, cohort,<br />

cross-sectional, and case control studies, are given preference. All<br />

manuscripts are subject to editorial revision to ensure they conform<br />

to the style adopted by the journal. There is a single blind kind <strong>of</strong><br />

reviewing system.<br />

Manuscripts should be prepared according to ICMJE guidelines<br />

(http://www.icmje.org/). Original manuscripts require a structured<br />

abstract. Label each section <strong>of</strong> the structured abstract with the<br />

appropriate subheading (Objective, Materials and Methods, Results,<br />

and Conclusion). Case reports require short unstructured abstracts.<br />

Letters to the editor do not require an abstract. Research or project<br />

support should be acknowledged as a footnote on the title page.<br />

Technical and other assistance should be provided on the title page.<br />

Original Manuscripts<br />

Title Page<br />

Title: The title should provide important information regarding the<br />

manuscript’s content. The title must specify that the study is a cohort<br />

study, cross-sectional study, case control study, or randomized study<br />

(i.e. Cao GY, Li KX, Jin PF, Yue XY, Yang C, Hu X. Comparative<br />

bioavailability <strong>of</strong> ferrous succinate tablet formulations without<br />

correction for baseline circadian changes in iron concentration in<br />

healthy Chinese male subjects: A single-dose, randomized, 2-period<br />

crossover study. Clin Ther. 2011; 33: 2054-2059).<br />

The title page should include the authors’ names, degrees, and<br />

institutional/pr<strong>of</strong>essional affiliations, a short title, abbreviations,<br />

keywords, financial disclosure statement, and conflict <strong>of</strong> interest<br />

statement. If a manuscript includes authors from more than one<br />

institution, each author’s name should be followed by a superscript<br />

number that corresponds to their institution, which is listed separately.<br />

Please provide contact information for the corresponding author,<br />

including name, e-mail address, and telephone and fax numbers.<br />

Running Head: The running head should not be more than 40<br />

characters, including spaces, and should be located at the bottom <strong>of</strong><br />

the title page.<br />

Word Count: A word count for the manuscript, excluding abstract,<br />

acknowledgments, figure and table legends, and references, should<br />

be provided not exceed 2500 words. The word count for an abstract<br />

should be not exceed 300 words.<br />

Conflict-<strong>of</strong>-Interest Statement: To prevent potential conflicts <strong>of</strong><br />

interest from being overlooked, this statement must be included in<br />

each manuscript. In case there are conflicts <strong>of</strong> interest, every author<br />

should complete the ICMJE general declaration form, which can be<br />

obtained at: http://www.icmje.org/coi_disclose.pdf.<br />

Abstract and Keywords: The second page should include an abstract<br />

that does not exceed 300 words. For manuscripts sent by authors<br />

in Turkey, a title and abstract in <strong>Turkish</strong> are also required. As most<br />

readers read the abstract first, it is critically important. Moreover, as<br />

various electronic databases integrate only abstracts into their index,<br />

important findings should be presented in the abstract.<br />

Objective: The abstract should state the objective (the purpose <strong>of</strong> the<br />

study and hypothesis) and summarize the rationale for the study.<br />

Materials and Methods: Important methods should be written<br />

respectively.<br />

Results: Important findings and results should be provided here.<br />

Conclusion: The study’s new and important findings should be<br />

highlighted and interpreted.<br />

Other types <strong>of</strong> manuscripts, such as case reports, reviews, perspectives,<br />

and editorials, will be published according to uniform requirements.<br />

Provide 3-10 keywords below the abstract to assist indexers. Use<br />

terms from the Index Medicus Medical Subject Headings List<br />

(for randomized studies a CONSORT abstract should be provided<br />

(http://www.consort-statement.org).<br />

Introduction: The introduction should include an overview <strong>of</strong> the<br />

relevant literature presented in summary form (one page), and what<br />

ever remains interesting, unique, problematic, relevant, or unknown<br />

about the topic must be specified. The introduction should conclude<br />

with the rationale for the study, its design, and its objective(s).<br />

Materials and Methods: Clearly describe the selection <strong>of</strong> observational<br />

or experimental participants, such as patients, laboratory animals, and<br />

controls, including inclusion and exclusion criteria and a description<br />

<strong>of</strong> the source population. Identify the methods and procedures in<br />

sufficient detail to allow other researchers to reproduce your results.<br />

Provide references to established methods (including statistical<br />

methods), provide references to brief modified methods, and provide<br />

the rationale for using them and an evaluation <strong>of</strong> their limitations.<br />

Identify all drugs and chemicals used, including generic names,<br />

doses, and routes <strong>of</strong> administration. The section should include only<br />

information that was available at the time the plan or protocol for<br />

the study was devised (http://www.strobe-statement.org/fileadmin/<br />

Strobe/uploads/checklists/STROBE_checklist_v4_combined.pdf).<br />

A-IV


Statistics: Describe the statistical methods used in enough detail to<br />

enable a knowledgeable reader with access to the original data to verify<br />

the reported results. Statistically important data should be given in the<br />

text, tables and figures. Provide details about randomization, describe<br />

treatment complications, provide the number <strong>of</strong> observations, and<br />

specify all computer programs used.<br />

Results: Present your results in logical sequence in the text, tables, and<br />

figures. Do not present all the data provided in the tables and/or figures in<br />

the text; emphasize and/or summarize only important findings, results,<br />

and observations in the text. For clinical studies provide the number<br />

<strong>of</strong> samples, cases, and controls included in the study. Discrepancies<br />

between the planned number and obtained number <strong>of</strong> participants<br />

should be explained. Comparisons, and statistically important values<br />

(i.e. P value and confidence interval) should be provided.<br />

Discussion: This section should include a discussion <strong>of</strong> the data.<br />

New and important findings/results, and the conclusions they lead<br />

to should be emphasized. Link the conclusions with the goals <strong>of</strong><br />

the study, but avoid unqualified statements and conclusions not<br />

completely supported by the data. Do not repeat the findings/results<br />

in detail; important findings/results should be compared with those<br />

<strong>of</strong> similar studies in the literature, along with a summarization. In<br />

other words, similarities or differences in the obtained findings/results<br />

with those previously reported should be discussed. Limitations<br />

<strong>of</strong> the study should be detailed. In addition, an evaluation <strong>of</strong> the<br />

implications <strong>of</strong> the obtained findings/results for future research<br />

should be outlined.<br />

References<br />

Cite references in the text, tables, and figures with numbers in<br />

parentheses. Number references consecutively according to the<br />

order in which they first appear in the text. <strong>Journal</strong> titles should be<br />

abbreviated according to the style used in Index Medicus (consult List<br />

<strong>of</strong> <strong>Journal</strong>s Indexed in Index Medicus). Include among the references<br />

any paper accepted, but not yet published, designating the journal<br />

and followed by, in press.<br />

Acknowledgments<br />

Acknowledge support received from individuals, organizations,<br />

grants, corporations, and any other source. For work involving a<br />

biomedical product or potential product partially or wholly supported<br />

by corporate funding, a note stating, “This study was financially<br />

supported (in part) with funds provided by (company name) to<br />

(authors’ initials)”, must be included. Grant support, if received,<br />

needs to be stated and the specific granting institutions’ names and<br />

grant numbers provided when applicable.<br />

Authors are expected to disclose on the title page any commercial or<br />

other associations that might pose a conflict <strong>of</strong> interest in connection<br />

with the submitted manuscript. All funding sources that supported<br />

the work and the institutional and/or corporate affiliations <strong>of</strong> the<br />

authors should be acknowledged on the title page.<br />

Ethics<br />

When reporting experiments conducted with humans indicate that<br />

the procedures were in accordance with ethical standards set forth<br />

by the committee that oversees human experimentation. Approval <strong>of</strong><br />

research protocols by the relevant ethics committee, in accordance<br />

with international agreements (Helsinki Declaration <strong>of</strong> 1975, revised<br />

2002 available at http://www.wma.net/e/policy/b3.htm, “Guide for<br />

the Care and use <strong>of</strong> Laboratory Animals” www.nap.edu/catalog/5140.<br />

html/), is required for all experimental, clinical, and drug studies.<br />

Patient names, initials, and hospital identification numbers should<br />

not be used. Manuscripts reporting the results <strong>of</strong> experimental<br />

investigations conducted with humans must state that the study<br />

protocol received institutional review board approval and that the<br />

participants provided informed consent.<br />

Non-compliance with scientific accuracy is not in accord with scientific<br />

ethics. Plagiarism: To re-publish-whole or in part-the contents<br />

<strong>of</strong> another author’s publication as one’s own without providing a<br />

reference. Fabrication: To publish data and findings/results that<br />

do not exist. Duplication: Use <strong>of</strong> data from another publication,<br />

A-VI


which includes re-publishing a manuscript in different languages.<br />

Salamisation: To create more than one publication by dividing the<br />

results <strong>of</strong> a study preternaturally.<br />

We disapprove <strong>of</strong> such unethical practices as plagiarism, fabrication,<br />

duplication, and salamisation, as well as efforts to influence the review<br />

process with such practices as gifting authorship, inappropriate<br />

acknowledgements, and references. Additionally, authors must<br />

respect participant right to privacy.<br />

On the other hand, short abstracts published in congress books that<br />

do not exceed 400 words and present data <strong>of</strong> preliminary research,<br />

and those that are presented in an electronic environment are not<br />

accepted pre-published work. Authors in such situation must declare<br />

this status on the first page <strong>of</strong> the manuscript and in the cover letter.<br />

(The COPE flowchart is available at: http://publicationethics.org)<br />

We use iThenticate to screen all submissions for plagiarism before<br />

publication.<br />

<strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong> uses plagiarism screening service<br />

to verify the originality <strong>of</strong> content submitted before publication.<br />

been made. After your manuscript has been submitted, a checklist will<br />

then be completed by the Editorial Assistant. The Editorial Assistant<br />

will check that the manuscript contains all required components<br />

and adheres to the author guidelines. Once the Editorial Assistant is<br />

satisfied with the manuscript it will be forwarded to the Senior Editor,<br />

who will assign an editor and reviewers.<br />

The Review Process<br />

Each manuscript submitted to The <strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong> is<br />

subject to an initial review by the editorial <strong>of</strong>fice in order to determine<br />

if it is aligned with the journal’s aims and scope, and complies with<br />

essential requirements. Manuscripts sent for peer review will be<br />

assigned to one <strong>of</strong> the journal’s associate editors that has expertise<br />

relevant to the manuscript’s content. All manuscripts are single-blind<br />

peer reviewed. All accepted manuscripts are sent to a statistical and<br />

English language editor before publishing. Once papers have been<br />

reviewed, the reviewers’ comments are sent to the Editor, who will<br />

then make a preliminary decision on the paper. At this stage, based on<br />

the feedback from reviewers, manuscripts can be accepted, rejected, or<br />

revisions can be recommended. Following initial peer-review, articles<br />

judged worthy <strong>of</strong> further consideration <strong>of</strong>ten require revision. Revised<br />

manuscripts generally must be received within 3 months <strong>of</strong> the date <strong>of</strong><br />

the initial decision. Extensions must be requested from the Associate<br />

Editor at least 2 weeks before the 3-month revision deadline expires;<br />

The <strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong> will reject manuscripts that are<br />

not received within the 3-month revision deadline. Manuscripts with<br />

extensive revision recommendations will be sent for further review<br />

(usually by the same reviewers) upon their re-submission. When a<br />

manuscript is finally accepted for publication, the Technical Editor<br />

undertakes a final edit and a marked-up copy will be e-mailed to the<br />

corresponding author for review and to make any final adjustments.<br />

Submission <strong>of</strong> Revised Papers<br />

When revising a manuscript based on the reviewers’ and Editor’s<br />

feedback, please insert all changed text in red. Please do not use<br />

track changes, as this feature can make reading difficult. To submit<br />

revised manuscripts, please log into your author center at ScholarOne<br />

Manuscripts. Your manuscript will be stored under “Manuscripts with<br />

Decisions”. Please click on the “Create a Revision” link located to the right<br />

<strong>of</strong> the manuscript title. A revised manuscript number will be created for<br />

you; you will then need to click on the “Continue Submission” button.<br />

You will then be guided through a submission process very similar to<br />

that for new manuscripts. You will be able to amend any details you<br />

wish. At stage 6 (“File Upload”), please delete the file for your original<br />

manuscript and upload the revised version. Additionally, please upload<br />

an anonymous cover letter, preferably in table format, including a<br />

point-by-point response to the reviews’ revision recommendations. You<br />

will then need to review your paper as a PDF and click the “Submit”<br />

button. Your revised manuscript will have the same ID number as the<br />

original version, but with the addition <strong>of</strong> an R and a number at the end,<br />

for example, TJH-2011-0001 for an original and TJH-2011-0001.R1,<br />

indicating a first revision; subsequent revisions will end with R2, R3,<br />

and so on. Please do not submit a revised manuscript as a new paper, as<br />

revised manuscripts are processed differently. If you click on the “Create<br />

a Revision” button and receive a message stating that the revision option<br />

has expired, please contact the Editorial Assistant at info@tjh.com.tr to<br />

reactivate the option.<br />

English Language Editing<br />

All manuscripts are pr<strong>of</strong>essionally edited by an English language<br />

editor prior to publication.<br />

Online Early<br />

The <strong>Turkish</strong> <strong>Journal</strong> <strong>of</strong> <strong>Hematology</strong> publishes abstracts <strong>of</strong> accepted<br />

manuscripts online in advance <strong>of</strong> their publication in print. Once an<br />

accepted manuscript has been edited, the authors have submitted<br />

any final corrections, and all changes have been incorporated, the<br />

manuscript will be published online. At that time the manuscript<br />

will receive a Digital Object Identifier (DOI) number. Both forms<br />

can be found at www.tjh.com.tr. Authors <strong>of</strong> accepted manuscripts<br />

will receive electronic page pro<strong>of</strong>s directly from the printer, and are<br />

responsible for pro<strong>of</strong>reading and checking the entire manuscript,<br />

including tables, figures, and references. Page pro<strong>of</strong>s must be returned<br />

within 48 hours to avoid delays in publication.<br />

ISH 2014 World Congress<br />

Report <strong>of</strong> the Chair <strong>of</strong> Council<br />

The XXXVth World Congress <strong>of</strong> the International Society <strong>of</strong><br />

<strong>Hematology</strong> (ISH) was held on September 4-5, 2014, in Beijing,<br />

China, hosted by the Chinese Society <strong>of</strong> <strong>Hematology</strong> (CSH). The<br />

President <strong>of</strong> the Congress was Pr<strong>of</strong>. Xiaojun Huang, the Co-Chairs<br />

were Pr<strong>of</strong>. Changgeng Ruan and Pr<strong>of</strong>. Saijuan Chen, and Pr<strong>of</strong>.<br />

Kaiyan Liu served as the Secretary-General. The ISH 2014 Beijing<br />

World Congress was highly successful and well organized, with a<br />

balanced scientific program in basic and clinical hematology. The<br />

venue was beautifully located next to the Beijing Olympic Garden<br />

with the spectacular Bird’s Nest Stadium and Beijing National<br />

Aquatics Center. There were 420 international members with<br />

a total <strong>of</strong> 1450 attendees from 34 countries, and 410 abstracts<br />

were submitted to the meeting. ISH Travel Awards sponsored<br />

by the Congress Organizing Committee were presented to 22<br />

junior hematologists from 20 countries. The scientific program<br />

started with Pr<strong>of</strong>. Zhu Chen’s excellent Miwa Lecture entitled<br />

“Acute Promyelocytic Leukemia: Achievements, Challenges and<br />

Expectations”. Zhu Chen (Shanghai Institute <strong>of</strong> <strong>Hematology</strong>)<br />

described his original contributions in the role <strong>of</strong> ATRA and<br />

its implications in APL. He reviewed the mechanisms <strong>of</strong> ATRA<br />

in APL, the efficacy <strong>of</strong> arsenic trioxide (ATO), its synergy with<br />

ATRA, and lessons learned from leukemic genomics. Chen also<br />

focused on treatment algorithms in low-, intermediate-, and highrisk<br />

APL patients. His talk was followed by Jacob M. Rowe (Shaare<br />

Zedek Medical Center, Jerusalem, Israel), who reviewed the role<br />

<strong>of</strong> stem cell transplantation, its indications, and survival data in<br />

AML. Rowe addressed clear indications and eligibility <strong>of</strong> adult<br />

AML patients for auto- and allogeneic HSCT. He also explained<br />

current challenges as well as controversies in allo-HSCT and RIC<br />

for older patients in CR1, the safety <strong>of</strong> MUD, the rate <strong>of</strong> relapse,<br />

the ability to “cure” at relapse, and GVL effect. In the IAD-EAD-<br />

APD joint session entitled “Genomic and Molecular Medicine in<br />

<strong>Hematology</strong>”, Seichi Ogawa (Kyoto, Japan) covered novel somatic<br />

mutations in AML and MDS. Ruben Mesa (Mayo Clinic, Scottsdale,<br />

Arizona, USA) clearly highlighted molecular targeting in myeloid<br />

malignancies and state-<strong>of</strong>-the art knowledge in myeloproliferative<br />

neoplasms. Mesa elegantly covered targeting issues from TKIs,<br />

i.e. imatinib, to novel therapeutics and their future implications.<br />

Tayfun Özçelik (Bilkent University, Ankara, Turkey) demonstrated<br />

very convincing data for careful interpretation <strong>of</strong> gene mutations in<br />

hematologic malignancies. Özçelik also cautioned us on “reading”<br />

and “translation” <strong>of</strong> genome sequencing data, giving excellent case<br />

examples from his original research. He explained his pioneering<br />

research in genomic sequencing and DNA-based diagnostics,<br />

including forensics in Turkey, as well as his recent discovery <strong>of</strong><br />

the VLDR mutation in cerebellar hypoplasia associated with<br />

“quadrupedal gait in humans”. During the congress there were also<br />

sessions on case-based presentations. The meeting also included<br />

various presentations on acute leukemias, lymphomas, CLL, CML,<br />

multiple myeloma, and coagulation and platelet disorders. The oral<br />

and poster sessions were well attended. During the ISH business<br />

meetings, David Gómez-Almaguer (Mexico) was elected as the<br />

new Secretary-General <strong>of</strong> the Inter-American Division (IAD),<br />

replacing Carlos Ponzinibbio (Argentina), who had completed his<br />

term. Sabri Kemahlı was reelected as the Secretary-General <strong>of</strong> the<br />

European-African Division (EAD).<br />

Future Perspectives<br />

The ISH is the only world hematology organization, established<br />

by the national hematology societies in 1946. The ISH has always<br />

had the strongest commitment to serve, educate, and provide<br />

up-to-date knowledge, as well as to collaborate with pr<strong>of</strong>essional<br />

societies including the ASH, ICSH, ISTH, and ISEH. As the newly<br />

elected Chair <strong>of</strong> Council, I envision a future for the Society as<br />

a strong source <strong>of</strong> global education in hematology, embracing all<br />

countries. I am planning to serve the Society within the framework<br />

<strong>of</strong> the following major topics: (a) to have an interactive, regularly<br />

updated, and user-friendly website; (b) to establish scientific<br />

working groups dealing with specified issues; (c) to establish a<br />

‘Code <strong>of</strong> Conduct’ for scientific ethics; (d) to make the biannual<br />

congresses a venue where all basic and clinical researchers are able<br />

to present their latest findings, and where hematologists in general<br />

Introduction<br />

One <strong>of</strong> the most problematic issues in hematological<br />

malignancies is the diagnosis <strong>of</strong> invasive fungal diseases. In<br />

particular, the difficulty <strong>of</strong> mycological diagnosis and the<br />

necessity <strong>of</strong> immediate intervention in cases <strong>of</strong> molds have<br />

led to the adoption <strong>of</strong> “surrogate markers” that do not verify<br />

but rather strongly suggest fungal infection. The markers<br />

commonly used are galactomannan (GM), beta-glucan, and<br />

imaging methods. Although there are numerous studies on<br />

these diagnostic approaches, none <strong>of</strong> these markers serve as<br />

support for the clinician, as in human immunodeficiency<br />

virus (HIV) or cytomegalovirus (CMV) infections. This<br />

paper has been prepared to explain the diagnostic tests. As<br />

molecular tests have not been standardized and are not used<br />

routinely in clinics, they will not be mentioned here.<br />

Conventional Microbiological Diagnostic Methods<br />

Clinical manifestations <strong>of</strong> invasive fungal infections<br />

(IFIs) generally are not agent-specific. Therefore,<br />

radiological, histopathological, and microbiological features<br />

are important in diagnosis. Although the radiological and<br />

histopathological findings are very important and provide<br />

possible evidence, the causative agent should be grown in<br />

culture and preferably be identified to the species level for<br />

definitive diagnosis. Accordingly, conventional (classical)<br />

microbiological diagnostic methods remain the gold<br />

standard in the diagnosis <strong>of</strong> IFIs [1,2,3,4].<br />

Conventional Microbiological Diagnostic Methods and<br />

Current Guidelines<br />

Direct microscopic examination and culture <strong>of</strong> the<br />

clinical samples constitute the conventional microbiological<br />

diagnostic methods.<br />

Direct Microscopic Examination<br />

Direct microscopic examination <strong>of</strong> the sample is a rapid<br />

and practical method that provides a chance for a possible<br />

pre-diagnosis. The results <strong>of</strong> direct microscopy also allow<br />

the interpretation <strong>of</strong> culture contamination in specimens<br />

from which a mold is isolated later. The major factors<br />

affecting the sensitivity <strong>of</strong> direct microscopic examination<br />

include the collection <strong>of</strong> a sufficient volume <strong>of</strong> a suitable<br />

clinical sample, application <strong>of</strong> staining methods within the<br />

frame <strong>of</strong> related principles, and performance <strong>of</strong> microscopic<br />

examination by experienced people on a sample involving<br />

the whole specimen. The sensitivity <strong>of</strong> direct microscopy<br />

widely varies depending on these factors. In order to<br />

evaluate the microscopic structures <strong>of</strong> fungi, different stains<br />

and wet coating methods can be used. Furthermore, very<br />

important evidence for the diagnosis <strong>of</strong> fungal infections can<br />

be acquired by histopathological evaluation <strong>of</strong> the biopsy<br />

samples. The staining methods used in microbiological<br />

and histopathological evaluation for the diagnosis <strong>of</strong><br />

opportunistic mycoses and the goals <strong>of</strong> use are summarized<br />

in Table 1 [5,6].<br />

Culture<br />

The isolation <strong>of</strong> fungi in culture is a conventional<br />

method, which remains the gold standard in providing<br />

the definitive diagnosis <strong>of</strong> IFIs. The collection <strong>of</strong> sufficient<br />

amounts <strong>of</strong> appropriate sample, rapid transport <strong>of</strong> the<br />

specimen to the laboratory, the informing <strong>of</strong> the laboratory<br />

<strong>of</strong> the tentative clinical diagnosis, and performance <strong>of</strong> the<br />

laboratory examinations without delay according to standard<br />

recommendations are among the main factors affecting the<br />

success <strong>of</strong> a culture [5,6,7]. The culture method carries some<br />

disadvantages along with important advantages; therefore,<br />

the use <strong>of</strong> additional serological diagnostic methods,<br />

particularly those aimed at early diagnosis, is recommended<br />

along with culture. The advantages and disadvantages related<br />

to the culture method [4,8,9] are presented in Table 2.<br />

Available Guidelines Related to the Microbiological<br />

Diagnosis <strong>of</strong> Invasive Fungal Infections<br />

In previous years, guidelines for or involving sections on<br />

fungal infection diagnosis have been published. The names<br />

and major content <strong>of</strong> these guidelines are summarized in<br />

Table 3.<br />

Recommendations for Direct Microscopic Examination<br />

and Culture Applications<br />

Direct microscopic examination and culture are the main<br />

indispensable methods for IFI diagnosis. Direct microscopic<br />

examination, due to its advantages such as being rapid<br />

and providing a possible pre-diagnosis, should necessarily<br />

be performed. The culture method, with advantages such<br />

as identification <strong>of</strong> the causative agent at species level and<br />

accordingly prediction <strong>of</strong> antifungal susceptibility pr<strong>of</strong>ile at<br />

the species level further allowing performance <strong>of</strong> antifungal<br />

susceptibility tests for that strain, is the gold standard that<br />

should be performed as the fundamental diagnostic method<br />

whenever possible. The use <strong>of</strong> culture in diagnosis has also<br />

received the highest recommendation level as the main<br />

diagnostic method in the current guidelines.<br />

Diagnosis <strong>of</strong> Fungemia: Isolation <strong>of</strong> Fungi in Blood<br />

Cultures<br />

Principles <strong>of</strong> collecting samples for the isolation <strong>of</strong> fungi<br />

in blood culture are the same as the standard principles <strong>of</strong><br />

blood culture [3]. Blood culture is an important method<br />

for the isolation <strong>of</strong> Candida, Fusarium, Scedosporium,<br />

343

thermally dimorphic fungi causing endemic mycosis, and<br />

the other yeasts with clinical importance [Blastoschizomyces<br />

(Saprochaete), Rhodotorula, Trichosporon, etc.] and for the<br />

diagnosis <strong>of</strong> infections caused by these fungi. If the fact that<br />

Turkey is not in an endemic region for thermally dimorphic<br />

fungi is considered, excluding possible travel-related<br />

infections, isolation <strong>of</strong> fungi causing endemic mycosis from<br />

blood does not carry primary importance. Fungi other<br />

than those causing endemic mycoses and expected to be<br />

isolated in blood culture can be isolated in blood culture<br />

at varying rates in our country, with Candida spp. being the<br />

leading isolate. However, the sensitivity <strong>of</strong> blood culture in<br />

candidemia diagnosis is generally below the desired level.<br />

Autopsy studies show that candidemia can be diagnosed by<br />

blood culture in 50-70% <strong>of</strong> cases [10,11].<br />

Different methods or parameters are being tested<br />

to enhance the sensitivity <strong>of</strong> blood culture in fungemia<br />

diagnosis, and the leading methods are lysis centrifugation<br />

method and use <strong>of</strong> fungal media. The lysis centrifugation<br />

method is especially recommended for the identification<br />

<strong>of</strong> dimorphic fungi in blood culture [12]. However,<br />

studies published in previous years, particularly those<br />

Advantages<br />

It is a “gold standard” method allowing definitive<br />

diagnosis.<br />

Provides a chance for identification to the genus<br />

and species level.<br />

Helps to estimate the antifungal susceptibility pr<strong>of</strong>ile<br />

(in accordance with the knowledge on primary<br />

resistance).<br />

Allows performance <strong>of</strong> antifungal susceptibility<br />

testing for the causative strain and hence determination<br />

<strong>of</strong> the differences in the susceptibility pr<strong>of</strong>ile at<br />

strain level.<br />

Disadvantages<br />

Sensitivity and specificity are variable and may be affected by several<br />

factors. Sensitivity rates are usually below the desired levels.<br />

Collection <strong>of</strong> a sufficient volume from the appropriate sample is<br />

among the most important factors affecting sensitivity.<br />

In the assessment <strong>of</strong> growth, cut<strong>of</strong>f <strong>of</strong> colony-forming units that<br />

can be used in the differentiation <strong>of</strong> contamination-colonization-infection<br />

is not available.<br />

False positive results due to contamination risk are possible (especially<br />

for molds).<br />

As the growth period is long (especially when molds are the causative<br />

agents), its benefit in early diagnosis is limited.<br />

involving open systems, reported data indicating that the<br />

use <strong>of</strong> the lysis centrifugation method might increase the<br />

risk <strong>of</strong> contamination [4,13]. Beyond that, as the lysis<br />

centrifugation method has been reported to be mainly<br />

useful in the diagnosis <strong>of</strong> dimorphic fungi, it does not carry<br />

primary importance in Turkey. On the other hand, use <strong>of</strong><br />

fungal media has been observed to be important not only<br />

for the isolation <strong>of</strong> fungi causing endemic mycosis, but also<br />

for the growth duration <strong>of</strong> yeasts (especially for Candida<br />

glabrata); use <strong>of</strong> fungal media has been reported to shorten<br />

the isolation period [14,15]. This finding is important, as<br />

C. glabrata is isolated in varying rates in blood culture at<br />

different centers in our country.<br />

When aerobic culture bottles <strong>of</strong> different automated<br />

systems are used for the isolation <strong>of</strong> fungi, the isolation rate<br />

<strong>of</strong> C. glabrata has been demonstrated to differ according to<br />

the automated system used, and the use <strong>of</strong> fungal media is<br />

particularly recommended with systems yielding low rates<br />

<strong>of</strong> isolation [16]. Other than that, study data are available<br />

showing that the use <strong>of</strong> fungal media can be beneficial in<br />

intensive care or hematology cases, where yeast growth<br />

in blood may be found together with resistant or multiple<br />

bacterial growth [14]. In light <strong>of</strong> these data, although current<br />

guidelines primarily stipulate the use <strong>of</strong> automated, validated<br />

blood culture systems, they emphasize that the sensitivity <strong>of</strong><br />

the system may change depending on the species studied and<br />

the system itself [3]. The knowledge that the use <strong>of</strong> blood<br />

culture bottles containing fungal media may shorten the<br />

growth period and the recommendation that the decision<br />

related to the use <strong>of</strong> these media should be made by the<br />

related center also appear in the guidelines [12]. Additionally,<br />

the Infectious Diseases Society <strong>of</strong> America (IDSA) and the<br />

American Society for Microbiology (ASM) guidelines <strong>of</strong>fer<br />

the use <strong>of</strong> 2 aerobic blood culture bottles instead <strong>of</strong> a single<br />

bottle for inoculation as an alternative to inoculation into<br />

fungal media, if yeast fungemia is suspected [17].<br />

Recommendation for the Isolation <strong>of</strong> Fungi from Blood<br />

Culture<br />

If the conditions <strong>of</strong> our country are taken into account,<br />

fungi likely to be isolated from blood include Candida spp.,<br />

the other yeasts, and Fusarium spp. In accordance with<br />

the recommendations <strong>of</strong> the guidelines and the studies<br />

performed using Candida spp., it is recommended that the<br />

decision <strong>of</strong> using fungal media for inoculation should be<br />

made considering the properties <strong>of</strong> the automated system<br />

and the patient population <strong>of</strong> that center.<br />

Routine Antifungal Susceptibility Testing and<br />

Recommendations<br />

Antifungal susceptibility testing should be performed<br />

with certain indications to direct antifungal treatment, not for<br />

all fungal strains isolated in routine practice. The indications<br />

<strong>of</strong> antifungal susceptibility testing have gained accuracy<br />

mostly for Candida strains, and comprehensive studies on<br />

other fungi, especially Aspergillus, are also being carried out.<br />

The indications for antifungal susceptibility testing include<br />

strains isolated from normally sterile sites, unresponsiveness<br />

to antifungal treatment, history <strong>of</strong> previous antifungal<br />

treatment use, and decreased susceptibility to antifungal<br />

drug(s) or isolates belonging to a resistant strain. Antifungal<br />

susceptibility testing should be performed and interpreted<br />

using reference methods for antifungal susceptibility tests<br />

from the Clinical and Laboratory Standards Institute (CLSI)<br />

or the European Committee on Antibiotic Susceptibility<br />

Testing (EUCAST) by staff and centers experienced in<br />

antifungal susceptibility testing and educated in mycology<br />

[3,4,18,19,20,21].<br />

Serological Tests<br />

Serological tests, developed to aid in early diagnosis<br />

and recommended to be used along with conventional<br />

methods, are another test group that carries importance<br />

in the microbiological diagnosis <strong>of</strong> IFIs. Currently, the<br />

important serological tests used in routine practice are the<br />

GM antigen test, beta-glucan test, cryptococcal antigen test,<br />

and combined mannan-anti-mannan testing.<br />

Galactomannan Test<br />

GM is a molecule composed <strong>of</strong> mannan and<br />

galact<strong>of</strong>uranose polymers found in the cell wall <strong>of</strong> Aspergillus<br />

spp. and some other molds (Penicillium and Fusarium spp.)<br />

[28,29]. It may be released into the environment during active<br />

growth <strong>of</strong> the fungus. It has been shown in several studies<br />

that determination <strong>of</strong> GM in serum, bronchoalveolar lavage<br />

(BAL) fluid, and other samples by a commercial kit using<br />

the sandwich enzyme immunoassay (EIA) method (Bio-Rad<br />

Laboratories, Marne-La-Coquette, France) is beneficial in<br />

the diagnosis <strong>of</strong> invasive aspergillosis (IA) [30,<strong>31</strong>,32,33].<br />

The results are read by a spectrophotometer and expressed<br />

as optical density index. It is strongly (AII) recommended<br />

by the ECIL that it be performed as a screening test in bone<br />

marrow transplants and in patients with hematological<br />

malignancies in whom the incidence <strong>of</strong> IA is high (5-15%).<br />

Again, strong evidence (AII level) supports screening to<br />

be performed at 2- to 3-day intervals at least twice a week,<br />

and an optical density index <strong>of</strong> >0.7 in a single sample and<br />

an optical density index <strong>of</strong> >0.5 in 2 consecutive samples<br />

suggests IA [22]. It is important to continue screening in<br />

patients diagnosed with IA by GM testing (BII) and it was<br />

demonstrated in studies that not observing a decrease in<br />

optical density may be related to poor prognosis [34].<br />

Additionally, revised European Organization for Research<br />

and Treatment <strong>of</strong> Cancer/Mycoses Study Group (EORTC/<br />

MSG) criteria emphasize that probable IA diagnosis can be<br />

made by GM positivity even if conventional microbiological<br />

evidence is not available [35].<br />

There are several factors affecting the performance <strong>of</strong><br />

the GM test. These factors are summarized in Table 4. It<br />

is emphasized that there may be false negative results in<br />

non-neutropenic patients receiving antifungal prophylaxis/<br />

treatment and in local infections, and false positive results<br />

in patients with Fusarium infections and in those receiving<br />

semi-synthetic β-lactam antibiotics [28,36,37,38,39,40].<br />

However, recent studies showed a very low rate <strong>of</strong> false<br />

positive GM related to piperacillin/tazobactam, which was<br />

considered as the most common antibiotic associated with<br />

false GM results [41,42,43]. Such kind <strong>of</strong> false positive<br />

results can be avoided by obtaining the serum sample just<br />

before the next dose <strong>of</strong> semi-synthetic β-lactam antibiotics<br />

[44].<br />

Other than serum, GM testing can be performed in BAL<br />

fluid. It was reported in all meta-analyses that the sensitivity<br />

<strong>of</strong> BAL GM is higher and the specificity is lower than that<br />

<strong>of</strong> serum GM testing [45,46,47]. It is recommended to<br />

perform GM analysis in bronchoscopic samples <strong>of</strong> patients<br />

at high risk <strong>of</strong> IA as its negative predictive value is high.<br />

It was pointed out that a BAL GM optical index <strong>of</strong> 3<br />

supports definitive diagnosis [48,49]. The values between<br />

these 2 limits are debatable. However, it is recommended<br />

in meta-analyses that the cut<strong>of</strong>f index value be taken as 1.5<br />

in patients with hematological malignancies and 1 in mixed<br />

patient populations [45,46]. A study comparing culture and<br />

GM in BAL fluid samples emphasized that growth might<br />

be expected when the optical index is >1, and a correlation<br />

with clinical studies was also demonstrated [50].<br />

There are also various factors affecting the performance<br />

<strong>of</strong> BAL GM testing. While the use <strong>of</strong> antifungal drugs active<br />

in molds leads to an apparent decrease in sensitivity, no<br />

significant difference could be found related to Aspergillus<br />

spp. Furthermore, there is no difference in the sensitivity <strong>of</strong><br />

BAL GM in patients with or without neutropenia [45,50].<br />

Similar to serum GM testing, the use <strong>of</strong> semi-synthetic<br />

β-lactam antibiotics may lead to false positive results [45].<br />

The standardization <strong>of</strong> bronchoscopy and bronchoscopic<br />

material is the most urgent problem that should be solved<br />

regarding BAL GM testing.<br />

Conclusively, GM is a biomarker that can be used along<br />

with clinical, radiological, and conventional microbiological<br />

tests in IA diagnosis. In centers where high-risk patients<br />

(bone marrow transplants and patients with hematological<br />

malignancies) are followed, if a result can be achieved in<br />

24 h and if computed tomography (CT) is available, it is<br />

recommended to be used as a screening test. In Turkey, GM<br />

testing twice a week for hospitalized patients is covered by<br />

reimbursement. Multidisciplinary follow-up is needed in<br />

high-risk patients and performance <strong>of</strong> bronchoscopy and<br />

BAL GM analysis after CT is important to exclude or support<br />

the diagnosis. There is a decrease in the sensitivity <strong>of</strong> GM<br />

testing, and especially serum GM, in patients receiving<br />

prophylaxis. It can be used as a diagnostic test when clinical<br />

findings develop in this kind <strong>of</strong> patient or at centers where<br />

scanning cannot be performed. However, it should not be<br />

forgotten that this is a supplementary test that should always<br />

be used together with other data.<br />

1,3-beta-D-Glucan Test<br />

The 1,3-beta-D-glucan (BG) test is one <strong>of</strong> the promising<br />

non-culture-based early diagnostic tests for the diagnosis <strong>of</strong><br />

IFIs. BG is a cell wall component <strong>of</strong> many fungi, especially<br />

Candida and Aspergillus spp. [51,52]. This test is based<br />

on the reaction <strong>of</strong> BG with factor G <strong>of</strong> the horseshoe crab<br />

coagulation cascade. In a preliminary study <strong>of</strong> 30 candidemic<br />

patients and 30 healthy controls, a serum BG level <strong>of</strong> 60 pg/<br />

mL was chosen as the cut<strong>of</strong>f. After determining this cut<strong>of</strong>f<br />

value, the BG test was evaluated in 283 patients with acute<br />

myeloid leukemia or myelodysplastic syndrome and the<br />

sensitivity, specificity, and negative predictive value <strong>of</strong> the<br />

test in proven and probable IFIs was 100%, 90%, and 100%,<br />

respectively [51]. Later, a cut<strong>of</strong>f value <strong>of</strong> 80 pg/mL, which<br />

is the currently accepted positive cut<strong>of</strong>f value for the test,<br />

was found to have better specificity in a multicenter study<br />

[53]. In an in vitro study, reactivity <strong>of</strong> 127 clinical fungal<br />

isolates belonging to 40 different genera was evaluated with<br />

the Glucatell assay [54]. Compared with the reactivity <strong>of</strong><br />

Aspergillus spp. with the BG test, Bipolaris spicifera, Sporothrix<br />

schenckii, Wangiella dermatitidis, and Penicillium marneffei<br />

isolates showed stronger reactivity and Paecilomyces spp.,<br />

Scopulariopsis spp., Fusarium spp., Phialophora verrucosa,<br />

and Exophiala jeanselmei showed some reactivity. Among the<br />

tested clinical yeast isolates, Saccharomyces spp., Rhodotorula<br />

rubra, and Trichosporon asahii were found to have similar<br />

test reactivity when compared to Candida spp. In a clinical<br />

study, sensitivity <strong>of</strong> the BG test for the diagnosis <strong>of</strong> Candida<br />

parapsilosis was found to be lower compared to other<br />

Candida spp. (78% vs. 90%, respectively) [53]. This test can<br />

also be positive in Pneumocystis jirovecii infections and the<br />

sensitivity <strong>of</strong> the test is very high: 96%, with a specificity <strong>of</strong><br />

84% [55]. The performance <strong>of</strong> the test in BAL fluid was also<br />

evaluated; however, the sensitivity <strong>of</strong> detecting an IFI using<br />

BAL specimens was not significantly increased over testing<br />

<strong>of</strong> serum alone [56].<br />

The BG test is usually not positive in the case <strong>of</strong> fungal<br />

colonization, and detection <strong>of</strong> circulating BG levels may<br />

be used as a surrogate marker not only for diagnosing IFIs<br />

but also for assessing the effectiveness <strong>of</strong> therapy [51,57].<br />

Diagnostic levels and serum kinetics <strong>of</strong> the BG test were<br />

found to be similar when compared to the GM antigen test<br />

for the diagnosis <strong>of</strong> IA in neutropenic patients [57]. In the<br />

same study, the combination <strong>of</strong> BG and GM antigen tests<br />

improved the specificity and positive predictive value to<br />

100%. In another clinical study performed in hematologic<br />

malignancy patients with IA, the sensitivity <strong>of</strong> the BG test<br />

and GM antigen test was 67% and 38%, respectively [39].<br />

Interestingly, diagnostic accuracy <strong>of</strong> the GM antigen test<br />

was 13% per serum sample in A. fumigatus-positive patients<br />

compared to 49% positivity in patients with non-fumigatus<br />

Aspergillus spp.; BG test positivity was similar between A.<br />

fumigatus and non-fumigatus Aspergillus spp.<br />

The overall pooled sensitivity and specificity <strong>of</strong> the<br />

test for the diagnosis <strong>of</strong> IFIs is 77% and 85% [58]. Those<br />

values seem promising, but there are no prospective<br />

studies evaluating the use <strong>of</strong> the BG test in the diagnosis<br />

and treatment <strong>of</strong> IFIs in hematology-oncology patients.<br />

Two consecutive positive antigenemia assays have very<br />

high specificity, positive predictive value, and negative<br />

predictive value but the sensitivity is not satisfactory, so the<br />

BG test needs to be combined with clinical, radiological,<br />

and microbiological findings [59]. Ideal cut<strong>of</strong>f values and<br />

timing <strong>of</strong> serum samples (like 2 or 3 times a week) should<br />

be determined. Currently, use <strong>of</strong> the test at least twice a<br />

week is moderately recommended in some guidelines for the<br />

screening or diagnosis <strong>of</strong> invasive Aspergillus and Candida<br />

infections [3,22]. Table 5 summarizes the differences<br />

between the GM and BG tests.<br />

Cryptococcal Antigen Tests<br />

The polysaccharide capsule that surrounds Cryptococcus<br />

ne<strong>of</strong>ormans is the target structure in serological tests, due<br />

to its antigenic structure. LA and EIA are the methods<br />

accepted in the serological diagnosis <strong>of</strong> cryptococcosis [22].<br />

The concordance <strong>of</strong> LA and EIA kits developed by different<br />

companies was found to be higher than 90% [62]. In a<br />

systematic review performed after January 1998 evaluating<br />

7 studies, 6 <strong>of</strong> which were retrospective, it was reported<br />

that cerebrospinal fluid (CSF) antigen test sensitivity<br />

in cryptococcal meningitis was 97% [63]. Although the<br />

effect <strong>of</strong> CSF antigen titer on disease prognosis has not<br />

been clearly defined, a CSF or serum antigen titer higher<br />

than 1/512 was associated with disseminated infection and<br />

unresponsiveness to treatment [64,65]. Antigen titer, tested<br />

again at least 7 days after the first test, was reported to<br />

decrease by 4-fold in patients with treatment response [66].<br />

The sensitivity <strong>of</strong> the serum antigen test was reported to be<br />

between 62% and 67% in pulmonary cryptococcosis and<br />

cases <strong>of</strong> other organ involvement. Antigen test specificity in<br />

both serum and CSF samples was determined to be 93-100%<br />

[64,65,66,67]. Serum antigen positivity has been reported<br />

in HIV-positive patients with disseminated disease. It should<br />

Turk J Hematol 2014;<strong>31</strong>:342-356<br />

be taken into account that serum antigen tests may give<br />

false negative results in cancer patients [22]. False positive<br />

test results at low titers were reported more frequently in<br />

LA tests than in EIA. False negative results are more likely<br />

with kits where clinical samples are not pre-treated with<br />

pronase [68]. In a study performed between January 1989<br />

and December 1999, 3828 CSF cryptococcal antigen tests<br />

<strong>of</strong> cancer patients were evaluated, and positive results were<br />

reported in 12 patients (0.3%). Six <strong>of</strong> these patients were<br />

found to have other conditions involving the central nervous<br />

system and it was recommended that test results <strong>of</strong> such<br />

patients be interpreted carefully because <strong>of</strong> probable false<br />

positive results [69]. Cryptococcal antigen testing in serum<br />

and CSF samples <strong>of</strong> patients with cryptococcal meningitis<br />

and disseminated cryptococcosis is recommended with<br />

an AII evidence level, and the use <strong>of</strong> the test in following<br />

treatment response is recommended with a CIII evidence<br />

level by the ECIL [22].<br />

Although cryptococcosis is not a common disease in<br />

Turkey, cryptococcal meningitis should be included in the<br />

differential diagnosis <strong>of</strong> central nervous system disorders<br />

<strong>of</strong> stem cell transplants or patients treated with intense<br />

chemotherapy regimens, and cryptococcal antigen testing<br />

should be performed on the CSF samples <strong>of</strong> such patients.<br />

Mannan/Anti-Mannan Tests<br />

Determination <strong>of</strong> mannan antigen (Mn) and antimannan<br />

antibody (A-Mn) by ELISA method has become<br />

one <strong>of</strong> the most frequently used serological methods in the<br />

diagnosis <strong>of</strong> invasive candidiasis [22]. A systematic review,<br />

evaluating 14 studies (13 retrospective, 1 prospective)<br />

including a total <strong>of</strong> 1220 patients (453 invasive candidiasis<br />

cases, 767 controls), reported that when performed<br />

separately the sensitivity <strong>of</strong> Mn and A-Mn tests was 58% and<br />

59%, respectively, whereas the specificity was 93% for Mn<br />

and 83% for A-Mn. However, if the positivity <strong>of</strong> one <strong>of</strong> these<br />

tests (Mn/A-Mn combination) is considered to be sufficient<br />

for diagnosis, sensitivity reaches 83% without a significant<br />

decrease in specificity (86%) [70]. In 73% <strong>of</strong> 45 patients<br />

with candidemia, at least one <strong>of</strong> the tests yielded positive<br />

results 6-7 days before the culture results were available, and<br />

in 21 patients who developed hepatosplenic candidiasis, a<br />

positive result was achieved approximately 16 days before<br />

the culture results [71,72]. Among Candida spp., the highest<br />

sensitivity was achieved for Candida albicans [70]. Seven<br />

<strong>of</strong> the studies evaluated in this review were performed in<br />

cancer patients, while the other 7 studies were carried out in<br />

intensive care units and surgery clinics. The heterogeneity<br />

<strong>of</strong> the methods used in the studies is intriguing. When the<br />

hematology-oncology patients were evaluated as a subgroup,<br />

the sensitivity <strong>of</strong> the test was 71-100% and the specificity<br />

ranged between 53% and 92% [70]. It was reported that<br />

response to Mn was especially significant after resolution <strong>of</strong><br />

neutropenia [73]. A study that compared the Mn, A-Mn, and<br />

BG test results in 56 candidemia patients, including 9 stem<br />

cell transplants or patients with hematological malignancies<br />

and 12 patients with solid tumors, reported the sensitivity<br />

<strong>of</strong> the tests as 58.9%, 62.5%, and 87.5%, respectively, and<br />

the specificity as 97.5%, 65%, and 85.5%, respectively. While<br />

the diagnostic sensitivity <strong>of</strong> the Mn/A-Mn combination<br />

increased to 89.3%, specificity remained at 63% [74]. ECIL<br />

guidelines recommend the use <strong>of</strong> Mn and A-Mn together<br />

with an evidence level <strong>of</strong> BII, and the use <strong>of</strong> Mn/A-Mn<br />

combination in the diagnosis <strong>of</strong> hepatosplenic candidiasis<br />

with an evidence level <strong>of</strong> BIII and in the diagnosis <strong>of</strong><br />

candidemia in hematology-oncology patients with evidence<br />

level CII. In the same guidelines, the use <strong>of</strong> the BG test in<br />

the diagnosis <strong>of</strong> invasive fungal disease is recommended at<br />

the BII evidence level [22]. In the ESCMID guidelines for<br />

the diagnosis <strong>of</strong> Candida infections, the use <strong>of</strong> Mn/A-Mn<br />

combination is recommended with the same evidence level<br />

as the use <strong>of</strong> BG.<br />

Recommendation<br />

Considering the economic burden <strong>of</strong> performing 2<br />

separate tests for the Mn/A-Mn combination, the similar<br />

clinical pictures in cancer patients with several other fungi<br />

besides Candida, and the panfungal character <strong>of</strong> the BG test<br />

contributing to the diagnosis <strong>of</strong> most <strong>of</strong> these conditions, the<br />

use <strong>of</strong> the BG test seems to be more suitable in neutropenic<br />

cancer patients in Turkey. Each center should decide which<br />

test they will use according to the incidence <strong>of</strong> invasive<br />

fungal disease, technical infrastructure, and target patient<br />

groups.<br />

Radiological Diagnosis <strong>of</strong> Invasive Fungal Infections<br />

CT is a more sensitive imaging method than chest X-ray<br />

in the diagnosis and differential diagnosis <strong>of</strong> pulmonary<br />

infections in immunosuppressed patients. CT is particularly<br />

indicated if chest X-ray is normal or near normal in patients<br />

suspected <strong>of</strong> pulmonary infections [75,76]. Currently,<br />

the entire lung can be scanned in a single breath-hold<br />

with multislice spiral CT (MSCT) systems. Continuously<br />

acquired slices <strong>of</strong> 5 mm in thickness can be used in routine<br />

evaluation. However, in order to identify the halo sign seen<br />

in fungal infections, thinner slices (1-2 mm) should be used<br />

in evaluation. The resolution <strong>of</strong> thin slices obtained with<br />

MSCT is sufficient to determine parenchymal lesions, and<br />

the use <strong>of</strong> classical high-resolution CT (HRCT) technique<br />

before MSCT is not necessary. MSCT especially provides<br />

better imaging than HRCT in patients who cannot hold their<br />

breath. However, while HRCT scans obtained in the prone<br />

position are helpful in the diagnosis <strong>of</strong> patients suspected<br />

<strong>of</strong> early fibrosis, HRCT scans obtained in expiration phase<br />

aid in the diagnosis <strong>of</strong> patients suspected <strong>of</strong> bronchiolitis<br />

obliterans [75].<br />

There is no need to use intravenous contrast media<br />

for MSCT for detection and differential diagnosis <strong>of</strong><br />

parenchymal infections in immunosuppressed patients.<br />

However, at the later stages, if there is suspicion <strong>of</strong> a rare<br />

vascular complication such as mycotic pulmonary artery<br />

aneurysm or aortic aneurysm, intravenous contrast media<br />

should be used. Intravenous contrast media are used for liver<br />

and spleen imaging <strong>of</strong> patients suspected <strong>of</strong> disseminated<br />

candidiasis [75].<br />

Symptoms <strong>of</strong> IFIs are not specific in immunosuppressed<br />

patients and differential diagnosis from infections caused by<br />

other microorganisms and noninfectious causes should be<br />

made. Therefore, radiologists should be informed in detail<br />

about the history and clinical-laboratory findings (primary<br />

disease, history <strong>of</strong> chemotherapy or radiotherapy, fever,<br />

respiratory distress, neutropenia, etc.) <strong>of</strong> the patients when<br />

they are evaluating thoracic CT scans.<br />

Thorax CT Findings in Invasive Fungal Infections<br />

Chest X-ray findings in immunosuppressed neutropenic<br />

patients are nonspecific and the assessment should be done<br />

by CT. A nodule is detected in the thorax CT scans <strong>of</strong> 82%-<br />

94% <strong>of</strong> patients with IFIs; the nodule is generally 1 cm or<br />

more in diameter. Nodules are more frequent in IFIs than in<br />

bacterial or viral infections. In particular, the “halo” sign at<br />

the periphery <strong>of</strong> the nodule or the “air crescent” sign within<br />

the nodule are findings in favor <strong>of</strong> IFIs [75,76,77].<br />

The halo sign is a ground-glass opacity surrounding<br />

a nodule or a mass in CT [78]. It was first described as<br />

a sign <strong>of</strong> hemorrhage around the foci <strong>of</strong> IA (Figure 1).<br />

Besides Aspergillus infections, it may be seen in Candida<br />

infections and mucormycosis. The halo sign is nonspecific,<br />

and it may be seen in other nodules with hemorrhage or<br />

as an in situ adenocarcinoma at the periphery <strong>of</strong> invasive<br />

adenocarcinoma. The halo sign is seen more frequently<br />

in patients with hematological malignancies and stem cell<br />

transplants than in solid organ transplants. While a halo sign<br />

is found in the majority <strong>of</strong> patients with invasive Aspergillus<br />

infection in the first days <strong>of</strong> infection (88-96%), its prevalence<br />

decreases with the progression <strong>of</strong> disease and it is present in<br />

18-19% <strong>of</strong> patients at the end <strong>of</strong> 2 weeks [79,80].<br />

The reversed halo sign, seen in approximately 4% <strong>of</strong><br />

IFIs, is defined as a focal, rounded area <strong>of</strong> ground-glass<br />

opacity surrounded by a complete or nearly complete ring <strong>of</strong><br />

consolidation. While it is seen in 19% <strong>of</strong> mucormycosis cases,<br />

its prevalence is lower than 1% in Aspergillus infections.<br />

Therefore, the reversed halo sign shows that mucormycosis<br />

should be considered, and it aids in selecting the appropriate<br />

antifungal agent in treatment [81].<br />

At 2-3 weeks after commencement <strong>of</strong> treatment, along<br />

with the resolution <strong>of</strong> neutropenia, cavitation develops within<br />

the consolidation or within the nodule. Cavitation usually<br />

shows that prognosis is good. An air crescent sign may be<br />

present or absent. The air crescent sign is a crescent-like air<br />

space within the cavity, separating a mass from the cavity<br />

wall [78] (Figures 2 and 3). Characteristically, it shows that<br />

Figure 1. Invasive Aspergillus infection showing a nodule<br />

with a halo sign at the periphery (arrows).<br />

Figure 2. Aspergillus infection showing a nodule with<br />

cavitation and air crescent sign (arrow).<br />

the infarcted lung is separated from the wall in IA. However,<br />

it can be seen in conditions such as tuberculosis infection,<br />

Wegener granulomatosis, lung cancer, and hemorrhage<br />

within the cavity. Although the air crescent sign is a rare<br />

finding in the early stages <strong>of</strong> invasive Aspergillus infections,<br />

the prevalence increases with the progression <strong>of</strong> disease [75].<br />

perihilar ground-glass opacities; the lung periphery is<br />

The nodule may grow within 10 days <strong>of</strong> commencing<br />

antifungal treatment in IFIs. Some researchers explained this<br />

by the gathering <strong>of</strong> immune cells along with the improvement<br />

in bone marrow. Hence, even though the nodule enlarges in<br />

the first 10 days <strong>of</strong> treatment, if the GM level is low and<br />

the number <strong>of</strong> neutrophils is high, it is recommended not to<br />

change the antifungal treatment [79,80].<br />

Aspergillus bronchopneumonia develops in<br />

approximately 10% <strong>of</strong> invasive Aspergillus infections. This<br />

infection, also known as airway IA, is characterized by<br />

the presence <strong>of</strong> Aspergillus organisms deep in the airway<br />

basement membrane. Clinical manifestations include<br />

bronchopneumonia, tracheobronchitis, and bronchiolitis.<br />

There may be consolidation areas predominantly in the<br />

peribronchiolar regions. Lobar consolidations may be rarely<br />

seen. Generally, there are no radiological findings in acute<br />

tracheobronchitis. In rare cases, there may be thickening<br />

<strong>of</strong> tracheal or bronchial walls. “Tree-in-bud” signs, which<br />

indicate endobronchiolar or peribronchiolar disease,<br />

and centrilobular nodules may be seen in bronchiolitis.<br />

Centrilobular nodules may also be detected in endobronchial<br />

spread <strong>of</strong> tuberculosis, atypical tuberculosis infections, viral<br />

pneumonias, and mycoplasma pneumonias. Therefore, when<br />

bronchiolitis findings are detected in a CT scan, primarily<br />

infections related to bacterial or viral microorganisms are<br />

considered, as they are more frequent [76].<br />

There is pulmonary involvement in 30% <strong>of</strong> cases <strong>of</strong><br />

mucormycosis. Radiological findings are not specific;<br />

consolidation, nodule, mass, cavitation, or abscess<br />

development may be seen (Figure 4) [76].<br />

In Pneumocystis jiroveci pneumonia, although chest<br />

X-rays are normal, perihilar ground-glass opacities showing<br />

patchy or geographic distribution can be identified in<br />

HRCT (Figure 5). Frequently, there is interlobular septal<br />

thickening. Cystic changes can be seen in the lungs <strong>of</strong><br />

acquired immunodeficiency syndrome (AIDS) patients<br />

receiving prophylaxis [76].<br />

The Diagnosis <strong>of</strong> Extra-Pulmonary Invasive Fungal<br />

Infections<br />

CT is the method <strong>of</strong> choice in suspicion <strong>of</strong> IFIs in the<br />

paranasal sinuses, and magnetic resonance imaging (MRI)<br />

should be performed in cases <strong>of</strong> suspicion <strong>of</strong> central nervous<br />

system involvement. Ultrasound, CT, or MRI can be used<br />

for examining the abdomen in disseminated candidiasis;<br />

typically small abscesses with a target-like appearance are<br />

seen in the spleen and liver [82].<br />

Interpretation<br />

Although currently there are various opportunities in the<br />

diagnosis <strong>of</strong> invasive fungal diseases, their implementation<br />

is somewhat difficult. None <strong>of</strong> these tests can be used<br />

to directly diagnose invasive fungal disease and they<br />

generally carry more meaning when they are used together.<br />

Radiological diagnosis seems to remain the most rapid and<br />

easy method to use; however, it carries a risk <strong>of</strong> false positive<br />

results. Serological tests such as GM, BG, and Mn/A-Mn<br />

are not available at all institutions and carry a risk <strong>of</strong> false<br />

positive or negative results, and delays in reporting make it<br />

difficult to use them in diagnosis. Molecular approaches are<br />

not yet recommended, as they are not standardized, carry a<br />

risk <strong>of</strong> false positive results, and do not have widespread use;<br />

however, in the very near future they have the potential to<br />

hold an important place in diagnosis.<br />

Abstract:<br />

Objective: The selectins are cell adhesion molecules that mediate the interactions among leukocytes, activated platelets, and<br />

endothelial cells. We aimed to investigate whether P-selectin polymorphisms are associated with thrombosis in patients with<br />

antiphospholipid syndrome (APS).<br />

Materials and Methods: The diagnosis and classification <strong>of</strong> APS were based on the report <strong>of</strong> an international workshop.<br />

Genomic DNA was extracted from citrated blood samples <strong>of</strong> all subjects. Three single nucleotide polymorphisms associated<br />

with the P-selectin coding region (S290N, c.1087G>A; N562D, c.1902G>A; T715P, c.2363A>C) were assessed.<br />

Results: There were 26 APS (65%) patients with thrombosis. The number <strong>of</strong> patients without thrombosis was 14 (35%).<br />

The frequency <strong>of</strong> the N562D-DN genotype was significantly higher in patients with APS than in healthy controls (p=0.003).<br />

The frequency <strong>of</strong> this genotype was significantly higher in patients with APS with thrombosis compared with patients with no<br />

thrombosis (p=0.03). The N562D-NN genotype was found at a higher frequency in patients with APS than in healthy controls<br />

(p=0.004).<br />

Conclusion: Our results suggest that the N562D polymorphism <strong>of</strong> the DN genotype <strong>of</strong> P-selectin is associated with an<br />

increased risk <strong>of</strong> thrombosis in patients with APS.<br />

Introduction<br />

Antiphospholipid syndrome (APS) is an autoimmune<br />

disease characterized by pregnancy morbidity and arterialvenous<br />

thrombosis in the presence <strong>of</strong> antiphospholipid<br />

antibodies (aPLAs) [1]. Although the relationship between<br />

aPLAs and thrombosis is known, the mechanisms <strong>of</strong><br />

thrombosis in APS has not been fully elucidated. Selectins,<br />

which are cell adhesion molecules, mediate the interactions<br />

among leukocytes, activated platelets, and endothelial cells.<br />

P-selectin, which can be identified as a soluble form in plasma,<br />

intercedes in the attachment and rolling <strong>of</strong> leukocytes on<br />

activated endothelial cells and is involved in the recruitment<br />

<strong>of</strong> leukocytes to thrombi [2,3]. Novel data suggest that the<br />

levels <strong>of</strong> soluble P-selectin (sP-selectin) are increased in<br />

APS patients with thrombosis [4]. In this study, we aim to<br />

investigate whether P-selectin polymorphisms are associated<br />

with thrombosis in patients with APS.<br />

Materials and Methods<br />

Patients and Controls<br />

Forty adult patients with APS and 40 healthy subjects<br />

with no history <strong>of</strong> thrombosis or autoimmune disease<br />

were included in the study. The history <strong>of</strong> disease, physical<br />

examination, and screening <strong>of</strong> lupus anticoagulant (LA) and<br />

serum anticardiolipin IgG and IgM levels were assessed for<br />

all patients. The diagnosis and classification <strong>of</strong> APS were<br />

based on an international consensus statement [1]. The<br />

subjects participating in the study had no LA and/or serum<br />

anticardiolipin-related systemic diseases or risk factors such<br />

as hypertension or hyperlipidemia for thrombosis.<br />

LA was diagnosed using activated partial thromboplastin<br />

time, kaolin clotting time, and Russell’s viper venom<br />

test according to published criteria [5]. IgG and IgM<br />

anticardiolipin antibodies were determined by enzyme-linked<br />

immunosorbent assay [6], and levels equal to or greater<br />

than 4 standard deviations were regarded as positive. The<br />

anticardiolipin antibody and LA tests were repeated 3 months<br />

after the first determination. APS patients with thrombosis had<br />

arterial and/or venous thrombosis as well as aPLA positivity.<br />

aPLA-positive patients with no thrombosis suffered from<br />

either first trimester fetal losses or thrombocytopenia and<br />

had persistently positive aPLA test results but no thrombotic<br />

complications over at least 3 years <strong>of</strong> follow-up.<br />

The study protocol was approved by the local ethics<br />

committee, and written and signed informed consent was<br />

obtained from all participants.<br />

Genotyping<br />

Genomic DNA was extracted from citrated blood samples.<br />

Three single nucleotide polymorphisms associated with<br />

the P-selectin coding region (S290N, c.1087G>A; N562D,<br />

c.1902G>A; T715P, c.2363A>C) were assessed. Polymerase<br />

chain reaction (PCR) was done in a total volume <strong>of</strong> 25 µL<br />

containing 2 U <strong>of</strong> Taq DNA polymerase (Fermentas), 2<br />

mmol/L MgCl 2 , 0.2 mmol/L <strong>of</strong> each dNTP, 2.5 µL <strong>of</strong> 10X PCR<br />

buffer, and 50 ng <strong>of</strong> genomic DNA.<br />

Allele specific primers were used in the<br />

following concentrations: 15 pmol <strong>of</strong> 290N-R<br />

(5’-TAAATGAATTCAGTCCATGGTTCCTACAT-3’), 5 pmol<br />

<strong>of</strong> 290S-R (5’-CACAGTCCATGGTTCCTTGAC-3’), 11 pmol <strong>of</strong><br />

290common (5’-TGTGTGGCTTTTCTCCTTTC-3’), 2 pmol <strong>of</strong><br />

562D-R (5’-ATTGCCCTACCAGCTTAAAGCCG TAGTC-3’),<br />

7 pmol <strong>of</strong> 562N-R (5’-CTCCAGCTTAAAGCCGTTCTT-3’),<br />

10.5 pmol <strong>of</strong> 562common (5’-TGAATATATAAGTGA<br />

ATGAACTTTGTG-3’), 3.5 pmol <strong>of</strong> 715P-R (5’-CCT GCT<br />

TGATAG GTT GCC ACG GAA GG-3’), 8 pmol <strong>of</strong> 715T-<br />

R (5’-GCAGGT TGG CAC GGT TGT-3’), and 9 pmol <strong>of</strong><br />

715common (5’-CTGTGA AAT GCT CAG AAC TAC ATG-<br />

3’). PCR amplification was carried out in a GeneAmp PCR<br />

System 9700 Thermo Cycler (Applied Biosystems, USA) using<br />

36 cycles <strong>of</strong> 94 °C for 25 s, 57 °C for 25 s, and 72 °C for 25 s.<br />

PCR products were separated on agarose gels and stained with<br />

ethidium bromide. The PCR products were 115, 205, and 182<br />

bp long for S290N, N562D, and T715P, respectively.<br />

Statistical Analysis<br />

Data are expressed as mean ± SD, number (%), or median<br />

(range). Test statistics were computed using the Mann-<br />

Whitney U test and the Kruskal-Wallis test. The chi-square<br />

test and odds ratio were used to calculate the 95% confidence<br />

intervals. Correlation coefficients and significance were<br />

calculated by Spearman’s test to assess the differences between<br />

groups. For all tests, a 2-tailed p-value <strong>of</strong>

vAdditionally, the relationship PSGL-1 VNRT polymorphisms<br />

and risk <strong>of</strong> thrombosis in APS patients was shown by Diz-<br />

Kucukkaya et al. [17]. The relationship between P-selectin<br />

polymorphism and thrombosis in APS patients was shown for<br />

the first time in our study. The c.1087G>A, c.1902G>A, and<br />

c.2363A>C polymorphisms lead to S290N, N562D, and T715P<br />

P-selectin gene variations, respectively. These variations are in<br />

the genetic region encoding the repeated part <strong>of</strong> the P-selectin<br />

gene and may be effective in binding P-selectin to PSGL-1.<br />

Therefore, our data are valuable in order to determine risk<br />

factors other than traditional ones for thrombosis in APS<br />

despite the fact that we did not estimate sP-selectin levels.<br />

In conclusion, our results suggest that the N562D<br />

polymorphism DN genotype <strong>of</strong> P-selectin is associated with<br />

an increased risk <strong>of</strong> thrombosis in patients with APS. The<br />

NN genotype <strong>of</strong> the same polymorphism might be protective<br />

against thrombosis in those patients. The effect <strong>of</strong> N562D<br />

polymorphism on sP-selectin levels will be studied in future<br />

work.<br />

Abstract:<br />

Objective: Anti-apoptotic proteins such as Bcl-2 and Bcl-xL may play a role in the survival <strong>of</strong> erythroid progenitor cells.<br />

Information about these proteins in patients with β-thalassemia minor is limited. We aimed to determine the levels <strong>of</strong> serum<br />

Bcl-2 in patients with β-thalassemia minor.<br />

Materials and Methods: Ninety-seven patients (60 females and 37 males with mean age <strong>of</strong> 29±21 years) with β-thalassemia<br />

minor were enrolled in this study. The diagnosis <strong>of</strong> β-thalassemia minor was based on whole blood counts, family history,<br />

and HbA2 levels estimated by high-performance liquid chromatography. The control group comprised 23 healthy adults (17<br />

females and 6 males with mean age <strong>of</strong> 58±9 years) without anemia. The levels <strong>of</strong> serum Bcl-2 were measured by enzyme-linked<br />

immunosorbent assay. Mann-Whitney U tests were used in statistical evaluation and p0.05), these levels were higher in β-thalassemia minor patients than controls.<br />

Conclusion: There are damaged beta chains in β-thalassemia minor. Therefore, it is expected that premature death <strong>of</strong> red<br />

blood cells may occur due to apoptosis. The mean age <strong>of</strong> the control group was higher than that <strong>of</strong> the β-thalassemia minor<br />

group; this may be why Bcl-2 levels were higher in the β-thalassemia minor group. It is known that older age constitutes a risk<br />

for increased apoptosis. Other proteins (Bad, Bax, etc.) and pathways [CD95 (Fas) ligand] associated with apoptosis should<br />

be evaluated in future studies including more patients.<br />

Yavaşoğlu İ, et al: Serum Bcl-2 Levels and β-Thalassemia Minor<br />

Özet:<br />

Amaç: Bcl-2 ve Bcl-xL gibi antiapoptotik proteinler eritroid progenitör hücrelerin yaşam süresinde rol oynayabilir. β-talasemi<br />

minör hastalarda bu proteinler ile ilgili bilgiler sınırlıdır. Biz, β-talasemi minörlü hastalarda serum Bcl-2 düzeylerinin<br />

belirlenmesi amaçladık.<br />

Gereç ve Yöntemler: β-talasemi minör tanılı doksan yedi hasta (60 kadın ve 37 erkek, yaş ortalamaları 29±21 yıl) bu<br />

çalışmaya dahil edildi. β-talasemi minör tanısı tam kan sayımı, aile öyküsü ve yüksek performanslı sıvı kromatografisine<br />

dayanan HbA2 düzeyleri ile konulmuştur. Kontrol grubu anemisi olmayan 23 sağlıklı yetişkin (17 kadın ve 6 erkek, yaş<br />

Introduction<br />

Translations or mutations <strong>of</strong> mRNA lead to a deficiency <strong>of</strong><br />

globin synthesis and thus cause thalassemia syndromes [1].<br />

Thalassemia syndromes are inherited disorders that occur as<br />

a result <strong>of</strong> abnormal synthesis <strong>of</strong> α/β-globin. Cytoplasmic<br />

inclusion bodies (including unpaired globin molecules)<br />

damage red blood cells. As a result, the life span <strong>of</strong> erythrocytes<br />

is shortened [1,2].<br />

Cell death is regulated by many intra- and extracellular<br />

signals. The ratio <strong>of</strong> anti-apoptotic molecules (Bcl-xl, Mcl-1,<br />

Bcl-w, A1, etc.) to apoptotic molecules (Bax, Bak, Bik, Bid,<br />

etc.) determines the future <strong>of</strong> the cell [3]. The Bcl-2 protooncogene<br />

is located on chromosome 18 and inhibits the<br />

apoptotic pathway. Bcl-2 is an important molecule in the early<br />

period <strong>of</strong> cell transformation [3,4].<br />

In recent years, some studies have been published about<br />

Bcl-2 genes to predict their role in the development <strong>of</strong> many<br />

solid tumors. However, there are few studies about the<br />

expression <strong>of</strong> Bcl-2 in patients with β-thalassemia minor [5].<br />

In this study, we aimed to determine the levels <strong>of</strong> serum<br />

Bcl-2 in patients with β-thalassemia minor.<br />

Materials and Methods<br />

Ninety-seven patients (60 females and 37 males with mean<br />

age <strong>of</strong> 29±21 years) with β-thalassemia minor were enrolled in<br />

this study. The diagnosis <strong>of</strong> β-thalassemia minor was based on<br />

whole blood counts, family history, and HbA2 levels estimated<br />

by high-performance liquid chromatography (Agilent 1100<br />

Series HPLC Value System, Waldbronn, Germany). The control<br />

group comprised 23 healthy adults (17 females and 6 males<br />

with mean age <strong>of</strong> 58±9 years) without anemia. The levels <strong>of</strong><br />

serum Bcl-2 were measured using a commercial enzyme-linked<br />

immunosorbent assay kit (Biosource, Cat. No. TMA 0<strong>31</strong>1,<br />

Camarillo, CA, USA). Age, sex, hemoglobin, hematocrit, mean<br />

corpuscular volume (MCV), whole blood cell counts, and<br />

serum levels <strong>of</strong> Bcl-2 were recorded. Venous blood samples<br />

were taken under the supervision <strong>of</strong> medical personnel and<br />

were measured with an ADVIA 2120 instrument (Siemens,<br />

Erlangen, Germany). Signed informed consent was obtained<br />

from all participants. SPSS 15 (SPSS Inc., Chicago, IL, USA) and<br />

the Mann-Whitney U test were used in statistical evaluation <strong>of</strong><br />

data and p0.05), levels in<br />

β-thalassemia minor patients were higher than in the controls.<br />

Bcl-2 levels <strong>of</strong> the patients with β-thalassemia minor and the<br />

control group are shown by dot-plot distribution in Figure 1.<br />

The relationships between age, hemoglobin, and MCV values<br />

and serum Bcl-2 levels are shown in Table 2.<br />

We evaluated serum Bcl-2 levels <strong>of</strong> 22 controls and 27<br />

patients with β-thalassemia minor <strong>of</strong> over 40 years. Bcl-2<br />

levels were statistically significantly higher among patients<br />

than in the control group (p=0.045).<br />

Discussion<br />

In this study, we did not find any significant difference in<br />

Bcl-2 levels between patients with β-thalassemia minor and<br />

controls.<br />

Antiapoptotic proteins (Bcl-2, Bcl-xL, and Mcl-1) are<br />

necessary for the survival <strong>of</strong> erythroid precursor cells [6].<br />

Proteins such as Bax and Bcl-xS trigger apoptosis <strong>of</strong> erythroid<br />

cells. According to some studies, Bcl-2 and Bax genes may<br />

be regulated by the p53 gene. If the ratio <strong>of</strong> anti-apoptotic<br />

proteins to pro-apoptotic proteins is more than 1, erythroid<br />

cells continue their life span [7]. Additionally, members <strong>of</strong> the<br />

Bcl-2 family may control apoptosis by acting as pro-oxidant<br />

agents [8].<br />

Erythropoietin increases Bcl-xL expression in erythroid-<br />

CFU colonies [5]. Significantly increased Bcl-xL and Mcl-1<br />

protein levels and the suppression <strong>of</strong> Bax protein are observed<br />

in CD34 (+) cells, induced by erythropoietin or stem cell<br />

factor [9]. Myelodysplastic syndrome (MDS) is characterized<br />

with ineffective erythropoiesis and increased apoptosis <strong>of</strong><br />

hematopoietic precursor cells. A correlation was observed with<br />

increased proteins associated with Bcl-2, but the mechanism is<br />

not yet fully understood [10].<br />

Levels <strong>of</strong> Bad, Bax, and Bcl-xS were especially higher in<br />

patients with MDS-refractory anemia (RA) or RA with ring<br />

sideroblasts [10]. Many changes in oncogenes and tumor<br />

suppressor genes may have a role in the pathogenesis <strong>of</strong> many<br />

diseases. Bcl-2 is located in the nucleus or membranes <strong>of</strong> the<br />

endoplasmic reticulum, while mitochondria were shown to<br />

be in neoplastic cells in B-cell neoplasms with t(14;18). The<br />

mechanism <strong>of</strong> Bcl-2 activation is still unknown; however,<br />

increased levels <strong>of</strong> cytochrome-c as a center <strong>of</strong> apoptosis may<br />

play a role [11]. Hockenbery et al. reported that Bcl-2 inhibits<br />

apoptosis by changing mitochondrial functions [12].<br />

Translations or mutations <strong>of</strong> mRNA lead to deficiency <strong>of</strong><br />

globin synthesis and thus cause thalassemia syndromes. It was<br />

reported in many studies that some cancers may be treated<br />

by regulation genes on pre-RNA and mRNA regions. Changes<br />

in apoptotic or anti-apoptotic pathways may be a result <strong>of</strong><br />

genetic modulation [13].<br />

β-Thalassemia is characterized by accelerated apoptosis<br />

<strong>of</strong> erythroid precursor cells. In many studies, limited data<br />

were reported about these proteins and genetic mechanisms<br />

in patients with thalassemia [2,3,4,5]. Increased synthesis <strong>of</strong><br />

fetal hemoglobin may improve the symptoms <strong>of</strong> β-thalassemia.<br />

Cytotoxic drugs such as hydroxyurea and cytarabine may affect<br />

the synthesis <strong>of</strong> fetal hemoglobin by stimulating precursor<br />

cells [1]. Castaneda et al. determined that short-chain fatty<br />

acids [arginine butyrate, sodium α-methylhydrocinnamate,<br />

sodium 2,2-dimethylbutyrate, sodium 3,4-(methylenedioxy)<br />

cinnamate, 2-(quinazolin-4-ylamino) butanoic acid, and<br />

4-(trifluoromethyl) sulfanyl aniline acetic acid] increased<br />

the erythroid-BFU colonies and endogenous fetal globin<br />

gene expressions [5]. In addition, anti-apoptotic genes were<br />

specifically regulated and Bcl-2 levels were increased by<br />

short-chain fatty acids. It is known that increased apoptosis is<br />

observed with older age [14].<br />

Cao et al. reported that neutrophils <strong>of</strong> patients with<br />

paroxysmal nocturnal hemoglobinuria expressed apoptosisrelated<br />

CD95, Bcl-2, and Bax without significant differences<br />

from the normal controls [15]. The results <strong>of</strong> a study by<br />

Ismail et al. suggest a more significant role for Bcl-x as an antiapoptotic<br />

regulator in CD34 (+) cells in aplastic anemia than<br />

Bcl-2 [16].<br />

The limitations <strong>of</strong> our study were the existence <strong>of</strong> an<br />

age gap between the 2 groups and a limited number <strong>of</strong><br />

Abstract:<br />

Objective: Conventional serologic typing <strong>of</strong> red blood cell systems other than ABO and RhD can be inaccurate and difficult<br />

to interpret in patients who have recently undergone blood transfusion. While molecular-based assays are not used routinely,<br />

the usefulness <strong>of</strong> genotyping was investigated in order to determine patients who may benefit from this procedure.<br />

Materials and Methods: Blood samples were taken from 101 patients with haemato-oncological, chronic renal, or<br />

gastroenterological diseases and from 50 donor controls; the samples were tested for Fy a and Fy b by applying serologic and<br />

genetic methods. All patients had received 3 or more units <strong>of</strong> RBCs during the last 3 months. An average <strong>of</strong> 6.1 RBC units were<br />

transfused per patient. The average length <strong>of</strong> time from transfusion until blood sampling was 24.4 days. The haemagglutination<br />

test was applied for serological analysis, and the restriction length polymorphism assay was used for genotyping.<br />

Results: In total, 33 (32.7%) patients showed positive reactions with anti-Fy a or anti-Fy b while being negative genetically. Falsepositive<br />

Fy a results were found in 23 samples, and false-positive Fy b in 10 specimens. During the last 3 months, significantly<br />

more RBC units were transfused to patients with discrepant results than to those with accurate phenotyping/genotyping results:<br />

median <strong>of</strong> 5 (mean ± SE: 6.85±0.69) versus median <strong>of</strong> 4 (mean: 5.71±0.51), respectively (p=0.025). The median length <strong>of</strong> time<br />

after the last transfusion was 25 days (mean: 28.72±2.23 days) in the group with accurate phenotyping/genotyping results<br />

versus a median <strong>of</strong> 14 days (mean: 15.52±1.95 days) in the group with discrepant results (p=0.001). Phenotypes and genotypes<br />

coincided in all donor samples.<br />

Conclusion: Genotyping assays for the Duffy system should be considered if the patient underwent blood transfusion less<br />

than 3 or 4 weeks before the sample collection. If the time frame from RBC transfusion exceeds 6 weeks, Duffy phenotyping<br />

can provide accurate results.<br />

Özet:<br />

Amaç: Eritrositlerin ABO ve RhD sistemleri dışındaki konvansiyonel serolojik tiplendirmesini son zamanlarda sık kan<br />

transfüzyonu yapılmış olan kişilerde yorumlamak yanlış ve zor olabilir. Bazı moleküler incelemeler henüz rutin olarak<br />

kullanılmamasına rağmen, genotiplendirmenin yararı bu işlemden fayda görecek hastaları belirlemek amacıyla incelenmiştir.<br />

Gereç ve Yöntemler: Hemato-onkoloijk, kronik böbrek hastalığı veya gastrointestinal hastalığı olan 101 hastadan ve kontrol<br />

grubu olan 50 kişiden karşılaştırmak üzere kan örnekleri alındı. Numuneler serolojik ve genetik yöntemler kullanılarak Fy a ve Fy b<br />

için test edildi. Bütün hastalara son 3 ay içinde 3 ve daha fazla ünite eritrosit süspansiyonu transfüzyonu yapılmıştı. Her hasta için<br />

ortalama transfüzyon 6,1 ünite olarak hesaplandı. Transfüzyondan örneklerin alınmasına kadar geçen ortalama süre 24,4 gündü.<br />

Hemaglütinasyon testi serolojik analiz için uygulandı, ve uzunluğu kısıtlanmış polimorfizm testi genotipleme için kullanıldı.<br />

Bulgular: Genetik olarak negatif olan, toplam 33 (%32,7) hastada anti-Fy a veya anti-Fy b ile pozitif reaksiyon elde edildi. Yirmi üç<br />

örnekte yanlış pozitif Fy a sonucu, 10 örnekte yanlış pozitif Fy b sonucu elde edildi. Son 3 ayda fenotiplendirme/genotiplendirme<br />

sonuçları tutarsız olanlarda uyumlu olanlara göre anlamlı olarak daha fazla eritrosit süspansiyonu transfüzyon yapılmıştı: sırasıyla<br />

ortanca 5 (ortalama ± SE: 6,85±0,69) ve ortanca 4 (ortalama ± SE: 5,71±0,51) (p=0,025). Fenotiplendirme/genotiplendirmesi<br />

sonuçları uyumlu olan grupta transfüzyondan test aşamasına kadar geçen ortanca süre 25 gün (ortalama: 28,72±2,23) iken,<br />

sonuçları uyumsuz çıkan grupta bu süre ortanca 14 (ortalama: 15,52±1,95) gündü. Tüm donör örneklerinde fenotip ve genotipler<br />

tutarlıydı.<br />

Sonuç: Örnek alınmasından 3 veya 4 hafta öncesinde transfüzyon alan kişilerde Duffy sistemi için genotiplendirme yapılması<br />

uygun olabilir. Eğer eritrosit süspansiyonu transfüzyonundan sonra geçen süre 6 haftadan fazla ise, Duffy fenotiplendirmeyle<br />

uygun ve güvenilir sonuçlar sunabilir.<br />

Introduction<br />

Patients who require multiple transfusions <strong>of</strong> red blood<br />

cells (RBCs), such as those with sickle cell disease (SCD) or<br />

β-thalassaemia, have a higher potential risk <strong>of</strong> alloimmunisation<br />

and delayed haemolytic transfusion reactions (DHTRs). The<br />

widely described risk <strong>of</strong> developing antibodies, mostly to<br />

Rh, Kell, Duffy, Kidd, and MNS systems, ranges from 18% to<br />

47% [1,2]. Programs to prevent alloimmunisation have been<br />

implemented in the centres treating patients with SCD and<br />

β-thalassaemia [1,3,4]. In addition to ABO and RhD matching,<br />

protocols range from providing limited antigen-matched<br />

RBCs for Rh and Kell to extended antigen-matched RBCs for<br />

Rh, Kell, Duffy, Kidd, and MNS systems prior to transfusion.<br />

Accurate phenotyping <strong>of</strong> multitransfused patients is<br />

<strong>of</strong>ten complicated, mostly due to the presence <strong>of</strong> circulating<br />

transfused donor RBCs in the recipient’s blood, leading to<br />

discrepancies in the assessment <strong>of</strong> tests results. The importance<br />

<strong>of</strong> the genotyping <strong>of</strong> clinically relevant antigens (such as C, c,<br />

E, K, Fya, Fy b , Jk a , Jk b , and S) in addition to phenotyping<br />

is still being discussed for patients with SCD, β-thalassaemia,<br />

and other haemoglobinopathies.<br />

However, there is a lack <strong>of</strong> information about the need<br />

for molecular testing for other groups <strong>of</strong> patients who<br />

depend on long-term RBCs transfusions, such as those with<br />

myelodysplastic syndrome, myel<strong>of</strong>ibrosis, or chronic renal<br />

failure [5,6,7]. Delayed haemolytic transfusion reactions are<br />

<strong>of</strong>ten an issue in these patients, affecting their quality <strong>of</strong> life<br />

and sometimes being fatal. The selection <strong>of</strong> antigen-negative<br />

RBCs in order to reduce alloimmunisation is <strong>of</strong>ten required<br />

for patients with long-term transfusions and for those with<br />

formed alloantibodies.<br />

The most common causes <strong>of</strong> DHTR include antibodies<br />

against Rh, Kell, Kidd, Duffy, and MNS systems [3,8,9,10].<br />

Serological testing and evaluation <strong>of</strong> the antigens and<br />

antibodies <strong>of</strong> the Duffy and Kidd systems are among the<br />

main problems in multitransfused patients. The correlation<br />

between serological and molecular typing <strong>of</strong> Duffy and Kidd<br />

systems demonstrates the benefits <strong>of</strong> genotyping in patients<br />

who depend on chronic RBC transfusions.<br />

The aim <strong>of</strong> our study was to estimate the value <strong>of</strong> DNAbased<br />

typing <strong>of</strong> Duffy and Kidd systems in chronically<br />

transfused non-SCD or β-thalassaemia patients, and to<br />

establish the impact <strong>of</strong> the amount <strong>of</strong> transfused RBCs and<br />

the time from the last transfusion on the discrepancy <strong>of</strong> the<br />

results.<br />

Materials and Methods<br />

Patients<br />

Peripheral blood samples were obtained from 101 patients<br />

with haematological and oncological diseases, chronic renal<br />

failure, and gastrointestinal diseases. All patients received 3 or<br />

more units <strong>of</strong> RBCs during the last 3 months. The inclusion<br />

criteria were the time frame from the last RBC transfusion<br />

being shorter than 8 weeks and the need for further<br />

transfusions. None <strong>of</strong> the patients were tested for Fy a , Fy b ,<br />

Jk a , or Jk b antigens before transfusions.<br />

Most <strong>of</strong> the RBC units received by the haematology<br />

patients and some <strong>of</strong> those received by the oncology patients<br />

were leucodepleted, while others were non-leucodepleted.<br />

Thus, 62 patients (61.4%) were transfused with leucoreduced<br />

RBCs, and 39 (38.6%) with entirely (or by more than half)<br />

non-leucoreduced RBCs. The median number <strong>of</strong> transfusion<br />

events per patient was 3 (mean: 3.33±0.21, range: 1-12). A<br />

median <strong>of</strong> 2 (mean: 1.85±0.04, range: 1-4) RBC units were<br />

administered per transfusion event and 4 (mean: 6.1±0.41,<br />

range: 3-24) units per patient.<br />

Donors<br />

In total, 49 blood donors served as controls in our study.<br />

Blood samples <strong>of</strong> donors were obtained by taking 1 or 2<br />

segments <strong>of</strong> tubes from RBC bags used for transfusions. This<br />

control group and the patient group were used to determine<br />

frequencies <strong>of</strong> Duffy and Kidd phenotypes in a Lithuanian<br />

population.<br />

Blood samples <strong>of</strong> all patients and donors were tested for<br />

Fya, Fy b , Jk a , and Jk b antigens by applying serological and<br />

molecular methods. Approval for the study was obtained from<br />

the Regional Bioethics Committee.<br />

Serotyping<br />

Peripheral blood samples were used for Duffy and Kidd<br />

phenotyping. Fya, Fy b , Jk a , and Jk b antigens were determined<br />

by haemagglutination using anti-Fy a , anti-Fy b , anti-Jk a ,<br />

and anti-Jk b Coombs reactive (polyclonal, human) reagents<br />

(Antitoxin GmbH, Germany) and DG Gel Coombs cards<br />

(Diagnostic Grifols, S.A., Spain). Each microtube <strong>of</strong> the<br />

card contained polymerised dextran in a buffered medium<br />

containing preservatives and low ionic strength solution,<br />

and was mixed with polyspecific anti-human globulin.<br />

The tests were performed according to the manufacturer’s<br />

recommendations. The results <strong>of</strong> the agglutination were<br />

expressed by using plus/minus values. Positive results were<br />

evaluated from 1+ to 4+.<br />

Genotyping<br />

The DNA was extracted from peripheral blood leucocytes<br />

using a DNA extraction kit (GeneJet Genomic DNA<br />

Purification Kit, Thermo Fisher Scientific, USA), following the<br />

manufacturer’s instructions. Polymorphism was identified by<br />

polymerase chain reaction-restriction length polymorphism<br />

(PCR-RFLP) analysis according to Reid et al. [7]. Briefly,<br />

each PCR reaction was carried out in a total volume <strong>of</strong> 25 µL<br />

containing 1X DreamTaq standard buffer, template DNA, 50<br />

pM <strong>of</strong> each primer, 2.0 mM MgCl 2 , 200 µM <strong>of</strong> each dNTP, and<br />

1 U <strong>of</strong> DreamTaq DNA polymerase (Thermo Fisher Scientific)<br />

with annealing at 62 °C.<br />

The amplification products were then digested overnight<br />

by restriction endonuclease BanI (Thermo Fisher Scientific),<br />

following the manufacturer’s instructions. The fragments were<br />

separated electrophoretically using 2% agarose gel containing<br />

ethidium bromide.<br />

The Duffy antigen is present in 2 major allelic forms,<br />

FY*A and FY*B, differing in an amino acid at position 42<br />

(Gly42Asp) <strong>of</strong> the Duffy antigen receptor. The amino acid<br />

change occurs because <strong>of</strong> G125A polymorphism in the Duffy<br />

antigen receptor for the chemokine gene (DARC).<br />

The Kidd antigen system is known to comprise 2<br />

major alleles, JK*A and JK*B, which result from a single<br />

nucleotide polymorphism (838G→A) in gene SLC14A1.<br />

The corresponding JK*A and JK*B antigens differ by a single<br />

amino acid (D280N).<br />

Statistical Analysis<br />

The comparison <strong>of</strong> medians between the groups was<br />

performed by applying the nonparametric Mann-Whitney U<br />

test. We did not compare the means because the values <strong>of</strong> the<br />

studied variables were not normally distributed (Kolmogorov-<br />

Smirnov test, p


Remeikiene D, et al: Duffy and Kidd Genotyping for Transfusions<br />

into 2 groups. The first group included those who received<br />

RBCs less than 4 weeks before and the second group more<br />

than 4 weeks before the sample collection. The influence <strong>of</strong><br />

the number <strong>of</strong> transfused RBCs on the disagreement <strong>of</strong> the<br />

results was also analysed.<br />

Duffy System<br />

A total <strong>of</strong> 33 (32.7%) phenotype/genotype discrepancies<br />

were assessed. However, in samples that did not contain one<br />

<strong>of</strong> the Duffy antigens, discrepant results were found in 68.8%<br />

<strong>of</strong> cases.<br />

Significant differences in phenotype/genotype<br />

disagreements between the 2 aforementioned groups were<br />

found in 29 and 4 cases, respectively (Table 2).<br />

The comparison <strong>of</strong> the duration <strong>of</strong> time after the last<br />

transfusion between the 2 groups <strong>of</strong> patients with accurate<br />

and discrepant phenotype/genotype results also showed<br />

a significant difference. The median <strong>of</strong> days after the last<br />

transfusion was found to be 14 (mean: 15.52±1.95) in the<br />

group with discrepant results versus 25 (mean: 28.72±2.23)<br />

in the group with accurate results (p=0.001).<br />

No effect <strong>of</strong> transfused RBCs per year on Duffy phenotyping<br />

and genotyping discrepancies was detected: 605 units<br />

[median:5 (mean: 8.91±1.58, range: 3-46)] were transfused<br />

to patients with accurate phenotype/genotype results, and 294<br />

units [median: 6 (mean: 8.91±1.4, range: 3-81] to those with<br />

discrepant results (p=0.207).<br />

Significantly different results were found when comparing<br />

the number <strong>of</strong> RBC units transfused during the last 3 months<br />

between the 2 aforementioned groups. A median <strong>of</strong> 5 (mean:<br />

6.85±0.69) units were transfused during this period to the<br />

patients with discrepant phenotype/genotype results versus<br />

4 (mean: 5.71±0.5) to those with accurate results (p=0.025).<br />

Disagreements between genotyping and serologic typing<br />

for Jka/Jk b were found in 32 (<strong>31</strong>.7%) blood samples, while<br />

in samples that did not contain one <strong>of</strong> the Kidd antigens,<br />

discrepant results were found in 65.3% <strong>of</strong> cases.<br />

Significantly more discrepant phenotype/genotype results<br />

were found in the samples <strong>of</strong> patients <strong>of</strong> the first group than<br />

in those <strong>of</strong> the second group, at 27 and 5 cases, respectively<br />

(Table 3).<br />

The time after the last transfusion was shown to be<br />

significantly different between the 2 groups <strong>of</strong> patients. The<br />

median <strong>of</strong> days after the last transfusion was found to be<br />

10.5 (mean: 16.09±2.45) in the group with discrepant results<br />

versus 25 (mean: 28.26±2.13) in the group with accurate<br />

results (p=0.01).<br />

No effect <strong>of</strong> the transfused RBCs per year on Kidd<br />

phenotyping and genotyping discrepancies was detected:<br />

649 units [median: 5 (mean: 9.41±1.66, range: 3-81)] were<br />

transfused to patients with accurate phenotype/genotype<br />

results, and 250 units [median: 8 (mean: 7.84±0.72, range:<br />

3-18)] to those with discrepant results (p=0.188). There was no<br />

difference with regard to the number <strong>of</strong> RBC units transfused<br />

during the last 3 months between the 2 aforementioned<br />

groups, either. A median <strong>of</strong> 6 (mean: 6.28±0.48) units were<br />

transfused during this period to the patients with discrepant<br />

phenotype/genotype results versus a median <strong>of</strong> 4 (mean:<br />

5.99±0.56) to those with accurate results (p=0.71).<br />

Phenotype Frequencies<br />

Genotyping results were used to determine the expected<br />

Duffy and Kidd phenotype frequencies. No differences were<br />

found when comparing these results with those <strong>of</strong> other<br />

authors [8,9]. The phenotypes <strong>of</strong> 101 patients and 49 controls<br />

are presented in Table 4.<br />

Discussion<br />

It is still disputable which situations require extended<br />

typing <strong>of</strong> transfused RBCs beyond routine matching for<br />

ABO, RhD, and existing antibodies. Although a number<br />

<strong>of</strong> studies found that SCD or β-thalassaemia patients may<br />

benefit from extended antigen matching, there is still a<br />

lack <strong>of</strong> recommendations in this context for other patients<br />

undergoing long-term RBC transfusions [1,11,12].<br />

Additional antibodies are known to occur in 20% to 90%<br />

<strong>of</strong> previously alloimmunised patients [13,14,15]. Schonewille<br />

et al. evaluated the incidence <strong>of</strong> new antibody formation with<br />

subsequent transfusion in 22% <strong>of</strong> alloimmunised haematooncology<br />

patients and in 20%-25% <strong>of</strong> the non-haematology/<br />

oncology cohort [14,15]. The transfusion <strong>of</strong> extended<br />

antigen-matched RBCs, including Duffy and Kidd systems,<br />

has been shown to lower alloimmunisation in about 70%<br />

<strong>of</strong> cases [16,17]. According to these studies as well as those<br />

investigating SCD patients, extended antigen matching could<br />

be recommended for haemato-oncology patients and other<br />

subjects who undergo long-term transfusions.<br />

We agree with the many authors who state that antigen<br />

typing <strong>of</strong> recently transfused patients is not always accurate, as<br />

their peripheral blood contains transfused cells [5,6,13,18,19].<br />

Several reports describe this type <strong>of</strong> discrepancy in up to<br />

10% <strong>of</strong> cases for the Duffy and Kidd systems by comparing<br />

phenotyping and genotyping results [6,18,20]. These findings<br />

differ from our data, which showed a much higher rate<br />

<strong>of</strong> discrepancies (32.7% and <strong>31</strong>.7%), although the results<br />

cannot be accurately compared because other authors failed<br />

to provide information about the number <strong>of</strong> transfused RBC<br />

units or the time frame from the last transfusion.<br />

In contrast to a number <strong>of</strong> previous studies [6,18,20,21,22],<br />

our data do not suggest the presence <strong>of</strong> additional Duffy<br />

system alleles (which are known to be associated with<br />

reduced or abolished gene expression) either in patients or in<br />

371

Remeikiene D, et al: Duffy and Kidd Genotyping for Transfusions<br />

donors. This is likely due to the fact that only genotypes <strong>of</strong> the<br />

Caucasian population were tested in our study.<br />

The phenotyping/genotyping results in a group <strong>of</strong> patients<br />

who received transfusions within a time period <strong>of</strong> 7 days before<br />

sample collection also differed from those reported earlier,<br />

particularly for the Kidd system [5,7]. In this group, a total<br />

<strong>of</strong> 24 samples in our study showed positive (2+ to 4+) results<br />

for Fya, Fy b , Jk a , and Jk b , although genotypically, 14 <strong>of</strong> them<br />

were Fya- or Fy b -negative, and 14 were Jk a - or Jk b -negative.<br />

Reid et al. described concordant phenotype/genotype results<br />

for 7 samples and mixed-field agglutination for 32 samples for<br />

Duffy antigens; they also described coincident results for 16<br />

samples and mixed-field agglutination for <strong>31</strong> samples for the<br />

Kidd system [7].<br />

Our data suggest the need for blood group genotyping<br />

(including the Duffy and Kidd systems), which was proposed<br />

by many authors [1,2,3,4,5,6,7,11,13,16,18,19,20,23,24,25].<br />

Nevertheless, one should determine when genotyping should<br />

replace serology or be combined with it for patients undergoing<br />

long-lasting RBC transfusions. This is particularly important<br />

for institutions that do not perform blood group genotyping<br />

routinely. We found in our study that Duffy genotyping/<br />

phenotyping disagreements depended on the number <strong>of</strong><br />

transfused RBC units during the last 3 months. However, it<br />

would be difficult to predict how many units would cause<br />

these discrepancies or to make specific recommendations.<br />

The limitation <strong>of</strong> our study is the small number <strong>of</strong> subjects,<br />

which complicated their grouping according to the number <strong>of</strong><br />

transfused RBC units.<br />

The results <strong>of</strong> our study regarding the effect <strong>of</strong> the length<br />

<strong>of</strong> time after the last transfusion on serology findings are<br />

useful in clinical practice. A significantly lower number <strong>of</strong><br />

Duffy and Kidd phenotyping/genotyping discrepancies was<br />

found in patients who underwent their last transfusions more<br />

than 3 (p=0.01 and p=0.017, respectively) or 4 (p=0.003 and<br />

p=0.018, respectively) weeks before the sample collection.<br />

Only one disagreement for the Duffy system (compared to<br />

3 for the Kidd system) was found when the time from the<br />

last transfusion was from 6 to 7 weeks. No discrepancies<br />

were found for either system when the last transfusion was<br />

performed more than 7 weeks before.<br />

Our data are also in agreement with previous reports<br />

indicating that the range <strong>of</strong> agglutination in mixed-field<br />

reactions does not predict the actual antigen typing [7]. For<br />

example, 10 patients in the discrepant group with 2+ reaction<br />

for Fya and 2+ or 3+ reaction for Fy b had FY*B/FY*B genotypes.<br />

In the group with accurate results, 7 genotypically FY*A/<br />

FY*B samples also showed 2+ agglutination with anti-Fya.<br />

An exception could be made for serologic reactions with the<br />

expression <strong>of</strong> 1+. All 5 <strong>of</strong> the 1+ reactions in the Duffy system<br />

typing as well as 8 respective reactions in the Kidd typing<br />

genetically showed no allele expression. Those reactions were<br />

classified as serologically negative. More research is needed to<br />

confirm this statement.<br />

Conclusions<br />

Our study showed that Duffy or Kidd phenotyping with<br />

agglutination tests is inappropriate for patients who have<br />

recently undergone blood transfusion. Genotyping should be<br />

considered when the patient underwent transfusion less than<br />

4 weeks before the sample collection. The group <strong>of</strong> patients<br />

who recently (

Abstract:<br />

Objective: This study aimed to investigate the impact <strong>of</strong> the different therapy regimens used in multiple myeloma (MM) on<br />

bone-specific alkaline phosphatase (BALP) levels.<br />

Materials and Methods: One hundred and thirteen patients with MM were included in the study. Patients were grouped<br />

according to the regimens they received, as follows: group 1, melphalan and prednisolone (MP); group 2, vincristine, adriablastin,<br />

and dexamethasone (VAD); group 3, thalidomide plus dexamethasone; and group 4, bortezomib plus dexamethasone. BALP<br />

levels were measured before treatment and at the third and sixth months <strong>of</strong> treatment. A fifth group consisted <strong>of</strong> patients in<br />

the post-treatment remission period at study entry (no-treatment group).<br />

Results: The BALP levels at the third and sixth months <strong>of</strong> the treatment were significantly higher than the pre-treatment<br />

levels in the bortezomib and the no-treatment groups, whereas no significant difference was observed in the MP, VAD, and<br />

thalidomide groups.<br />

Conclusion: Considering that BALP is a surrogate marker <strong>of</strong> bone formation, our study suggests that bortezomib more<br />

efficiently leads to the improvement <strong>of</strong> bone disease in myeloma than other treatment options.<br />

Introduction<br />

Multiple myeloma (MM) is a malignant disease<br />

characterized by anemia, monoclonal protein in the serum<br />

and/or the urine, osteolytic bone lesions, hypercalcemia,<br />

and renal insufficiency resulting from uncontrollable clonal<br />

hyperproliferation <strong>of</strong> plasma cells in bone marrow [1,2,3]. The<br />

skeletal system problems that appear either at the time <strong>of</strong> the<br />

diagnosis or during the progression <strong>of</strong> MM cause a decrease<br />

in the quality <strong>of</strong> life and lead patients to present to health<br />

services. The rate <strong>of</strong> skeletal system-related complications<br />

including bone pain, osteolytic lesions, and pathological<br />

fractures reaches up to 80% in patients with MM [4,5]. In the<br />

studies concerning MM, it has been demonstrated that there<br />

is a significant relation between the bone-specific alkaline<br />

phosphatase (BALP) levels and bone pain, lytic lesions, and<br />

bone fractures [1,2].<br />

Until now, there has been no large study showing the effect<br />

<strong>of</strong> various therapy options used in the treatment <strong>of</strong> MM on the<br />

changes in bone metabolism caused by myeloma. The aim <strong>of</strong><br />

the present study was to investigate the relationship between<br />

pre-treatment and post-treatment BALP levels and the therapy<br />

options in patients with MM, and to expose the effect <strong>of</strong> these<br />

therapy options on bone metabolism.<br />

Materials and Methods<br />

Patients<br />

One hundred and thirteen patients diagnosed with MM<br />

in accordance with the criteria <strong>of</strong> the International Myeloma<br />

Working Group and followed in the <strong>Hematology</strong> Division <strong>of</strong><br />

the Internal Medicine Department <strong>of</strong> the İstanbul University<br />

Cerrahpaşa Medical Faculty between November 2006 and July<br />

2009 were included in the present study. The study cohort<br />

consists <strong>of</strong> patients with MM that have been followed and/<br />

or treated for at least 6 months regardless <strong>of</strong> their age, sex,<br />

stage <strong>of</strong> the disease, and type <strong>of</strong> the therapy. Continuity <strong>of</strong> the<br />

out-patient clinic visits for follow-ups was confirmed, and the<br />

general status <strong>of</strong> the patients had not deteriorated. The study<br />

was planned in accordance with the Helsinki Declaration,<br />

and the approval <strong>of</strong> the Ethics Committee <strong>of</strong> the İstanbul<br />

University Cerrahpaşa Medical Faculty was obtained. Written<br />

informed consent <strong>of</strong> the patients to participate in the study<br />

was received. Participants who chose to quit the study for any<br />

reason, cases lacking any results from the analyses done for<br />

the evaluations, cases <strong>of</strong> non-continuance <strong>of</strong> follow-up visits,<br />

and patients who died before completing the follow-up period<br />

were not included in the study.<br />

Methods<br />

The melphalan and prednisone (MP; group 1); vincristine,<br />

adriamycin (doxorubicin), and dexamethasone (VAD; group<br />

2); thalidomide (group 3); and bortezomib (group 4) regimens<br />

were as defined before [6,7,8,9]. International Myeloma<br />

Working Group response criteria were used while evaluating<br />

the patients’ responses to these treatment modalities [10]. All<br />

patients had received monthly zoledronic acid treatment, and<br />

since the serum BALP values could be affected, the patients<br />

with renal insufficiency who required dialysis were excluded<br />

from the study population.<br />

The levels <strong>of</strong> BALP (initial, third month, and sixth<br />

month), serum protein electrophoresis, C-reactive protein,<br />

erythrocyte sedimentation rate, lactate dehydrogenase,<br />

total protein, albumin, hemoglobin, beta-2 microglobulin,<br />

creatinine, glomerular filtration rate, calcium, quantitative<br />

immunoglobulin and light chain, and immun<strong>of</strong>ixation<br />

electrophoresis <strong>of</strong> all patients were analyzed in the Fikret Biyal<br />

Central Biochemistry Laboratory <strong>of</strong> the İstanbul University<br />

Cerrahpaşa Medical Faculty.<br />

Four milliliters <strong>of</strong> peripheral blood was taken from<br />

all patients into tubes containing EDTA both prior to the<br />

treatment and at the third and sixth months <strong>of</strong> treatment.<br />

BALP levels were measured by means <strong>of</strong> radioimmunoassay<br />

technique using the Ostease BALP Kit <strong>of</strong> International<br />

Diagnostic Systems Ltd. The normal ranges <strong>of</strong> BALP levels<br />

among pre-menopausal women, post-menopausal women,<br />

and men are 11.6-29.6 U/L, 14.2-42.7 U/L, and 15.0-41.3 U/L,<br />

respectively, as given by the manufacturer.<br />

There was no significant difference according to the pretreatment,<br />

third month, and sixth month mean BALP values<br />

among the MP, VAD, and thalidomide groups (p=0.069,<br />

p=0.148, p=0.254; Table 2). There was a significant change<br />

between the pre-treatment, third month, and sixth month<br />

mean BALP values in the bortezomib group (p=0.002). While<br />

the sixth month mean BALP value was significantly higher<br />

than the pre-treatment and third month mean BALP values<br />

(p=0.003), no significant difference was found between pretreatment<br />

and third month values (p>0.05). Significant change<br />

was found between initial, third month, and sixth month mean<br />

BALP values <strong>of</strong> the no-treatment group (p=0.0001) (Table 2).<br />

The initial mean BALP values were found to be significantly<br />

lower than the third and sixth month mean BALP values<br />

(p=0.001, p=0.035). Since the patient numbers in the groups<br />

were relatively small, especially when divided according to DS<br />

stages, we did not compare BALP values among the patient<br />

groups according to the DS staging system.<br />

Discussion<br />

Myeloma-induced skeletal problems negatively affect the<br />

quality <strong>of</strong> life [11,12,13].<br />

The activation <strong>of</strong> osteoclasts and the suppression <strong>of</strong><br />

osteoblasts are the main events in MM. Bone formation<br />

is suppressed. Therefore, bone lesions are totally lytic in<br />

patients with MM [14]. Osteoclasts usually proliferate on the<br />

resorptive surfaces adjacent to the myeloma cells in the bone<br />

and do not proliferate in the regions that do not have tumoral<br />

involvement [15].<br />

Until the new treatment options were developed, MP,<br />

high-dose dexamethasone, VAD, and multi-drug combination<br />

chemotherapies were the combinations most frequently used<br />

in MM [16,17,18,19]. The new drugs that have recently been<br />

included in the treatment <strong>of</strong> MM are molecular-targeted drugs<br />

that target the micro-environment <strong>of</strong> the bone. Among those<br />

drugs, good therapy responses have been obtained with the<br />

combination <strong>of</strong> thalidomide, bortezomib, or lenalidomide with<br />

high-dose dexamethasone [20]. The treatment <strong>of</strong> myeloma<br />

bone disease has mainly been directed toward the inhibition<br />

<strong>of</strong> osteoclastic activity with the use <strong>of</strong> bisphosphonates [11].<br />

Anti-myeloma therapies that cause remission are usually<br />

not accompanied by an increase in the osteoblast indicators or<br />

in bone mineral density [21,22].<br />

When compared with patients with monoclonal<br />

gammopathy <strong>of</strong> undetermined significance or with the<br />

healthy controls, deterioration in osteoblastic activity in the<br />

patients with MM was observed with a decrease in osteocalcin<br />

or BALP levels [23]. In healthy subjects, BALP accounts for<br />

approximately 50% <strong>of</strong> the total alkaline phosphatase (TAP) in<br />

the circulation. BALP reflects both the bone formation and the<br />

bone degradation more sensitively than alkaline phosphatase<br />

[24]. Serum BALP shows a remarkable correlation with the<br />

dynamic parameters <strong>of</strong> bone formation [25].<br />

The fact that there is a relationship between the increase<br />

in serum BALP and osteoblastic activity in MM has been<br />

demonstrated in another study, as well [26]. Some preclinical<br />

trials again raised the suggestion that the inhibition <strong>of</strong><br />

proteasome might enhance osteoblastic activity [27]. From<br />

this perspective, proteasome inhibitors represent a group <strong>of</strong><br />

new anti-tumor drugs [28] and have strong anti-myeloma<br />

effects [29].<br />

Bortezomib, which is a proteasome inhibitor, is the first<br />

drug used in the treatment <strong>of</strong> MM that has similar effects on the<br />

osteoblastic function together with important anti-myeloma<br />

activity [11,14,15,30,<strong>31</strong>,32,33,34]. Bortezomib, a firstgeneration<br />

proteasome inhibitor that has been developed to be<br />

used as an anti-neoplastic agent, inhibits the 26S proteasome<br />

that is located on the chymotryptic region and inhibits the<br />

proliferation <strong>of</strong> chemotherapy-sensitive, chemotherapyresistant,<br />

and dexamethasone-resistant MM cells as well as the<br />

proliferation <strong>of</strong> MM cells that have been recently isolated from<br />

the bone marrow <strong>of</strong> the patients [35,36].<br />

The first evidence concerning the effect <strong>of</strong> bortezomib<br />

on bone metabolism came from a 63-year-old female<br />

1 mg/m 2 bortezomib on days 1, 4, 8, and 11 <strong>of</strong> a 21-day cycle.<br />

The paraprotein response <strong>of</strong> myeloma was associated with a<br />

rapid increase in TAP. The effect continued for a few therapy<br />

cycles and the BALP values were normal during the relapses<br />

[9,37]. Sezer et al. reported a negative correlation between<br />

RANKL and osteoprotegerin [38]. Subsequently, a significant<br />

increase was determined in BALP levels in the group receiving<br />

bortezomib as compared to the control group, and this finding<br />

was interpreted as osteoblastic activity increasing the effect<br />

<strong>of</strong> bortezomib. Thereafter, the change in alkaline phosphatase<br />

levels was retrospectively analyzed and evaluated in 2 large<br />

studies (APEX and SUMMIT studies) in which bortezomib<br />

was used as a single agent in patients with recurrent/refractory<br />

MM [39,40]. Data obtained from all these studies show that<br />

bortezomib increases osteoblastic activity.<br />

In the present study, the initial, third month, and sixth<br />

month BALP levels were not significantly different in the<br />

MP, VAD, and thalidomide groups. Significant change was<br />

observed among the pre-treatment, third month, and sixth<br />

month mean BALP values <strong>of</strong> the bortezomib group. The sixth<br />

month mean BALP value was found statistically higher than<br />

the pre-treatment and third month mean BALP values.<br />

Significant change was observed between the initial,<br />

third month, and sixth month mean BALP values <strong>of</strong> the notreatment<br />

group. The initial mean BALP value was found<br />

statistically lower than the third and sixth month mean BALP<br />

values, whereas no statistically significant difference was<br />

observed between the other times. According to our findings,<br />

the high BALP values at the third and sixth months <strong>of</strong> therapy<br />

in the group receiving bortezomib can be interpreted as the<br />

osteoblastic activity being increased in this group.<br />

The results <strong>of</strong> our study are also in line with the clinical<br />

findings <strong>of</strong> Shimazaki et al., who defined high BALP levels<br />

following bortezomib combination therapy in resistant MM<br />

[41]. In addition, it was reported that there was no significant<br />

change in BALP levels in patients receiving dexamethasone,<br />

whereas there was a significant increase in BALP levels in the<br />

myeloma patients receiving bortezomib [39,42]. In the present<br />

study, we determined a significant difference between the pretreatment<br />

and post-treatment BALP values with bortezomib<br />

therapy. On the other hand, the degree <strong>of</strong> improvement<br />

obtained by chemotherapy not being in line with the healing<br />

degree <strong>of</strong> the bone disease may be related to the increased<br />

osteoclastic activity <strong>of</strong> MM even in the plateau period [21,22].<br />

In the present study, the third and sixth month mean BALP<br />

values being high in the no-treatment group may be explained<br />

by decreased osteoclastic and increased osteoblastic activity,<br />

because the majority <strong>of</strong> the patients in this group were in<br />

remission (complete and/or almost complete). In some studies<br />

concerning MM, it was determined that BALP levels were<br />

associated with bone pain, lytic lesions, and bone fracture<br />

[43]. From this point <strong>of</strong> view, achieving complete remission<br />

and treating the bone disease appear to be important aims for<br />

decreasing the morbidity and mortality <strong>of</strong> the patients.<br />

In conclusion, the use <strong>of</strong> proteasome inhibitors such as<br />

bortezomib, together with bisphosphonates, will no doubt<br />

lead to much more positive outcomes in myeloma treatment.<br />

Abstract:<br />

Objective: Increased risk for non-Hodgkin lymphoma (NHL) is associated with infections and environmental agents. We<br />

hypothesized that these factors chronically trigger the T helper-2 (Th2) pathway and result in lymphoma. We investigated the<br />

role <strong>of</strong> the Th2 pathway by exploring the relationships between components <strong>of</strong> the Th2 pathway, interleukin (IL)-10, IL-4,<br />

immunoglobulin E (IgE), and eosinophils, and prognostic markers <strong>of</strong> NHL.<br />

Materials and Methods: Thirty-one NHL patients and 27 healthy controls were enrolled. IL-10, IL-4, IgE, and eosinophils<br />

were measured. IL-4 and IL-10 were analyzed with the enzyme amplified sensitivity immunoassay method.<br />

Results: High IL-10 levels were correlated with several poor prognostic features, short early survival, and lymphopenia. There<br />

was a positive correlation between albumin and IL-4 levels and a negative correlation between IL-10 and albumin. There was<br />

no relationship related with eosinophils and IgE. We found remnant increased IL-4, which could be a clue for the triggering<br />

<strong>of</strong> the Th2 pathway in the background.<br />

Conclusion: There is a need for differently designed studies to detect the place <strong>of</strong> the Th2 pathway in NHL.<br />

Introduction<br />

Increased risk for Non-Hodgkin lymphoma (NHL)<br />

is associated with infections, environmental agents, and<br />

immune suppression. The T helper-2 (Th2) immune reaction<br />

is typically characterized by expression <strong>of</strong> interleukin (IL)-4,<br />

IL-5, IL-9, IL-10, and IL-13; the recruitment <strong>of</strong> eosinophils,<br />

basophils, and mast cells; and immunoglobulin (Ig) G-to-IgE<br />

antibody class switching [1]. Exposure to an antigen may cause<br />

an allergic reaction, but chronic exposure to the same allergen<br />

at a low dose can cause immune tolerance via T regulatory<br />

(T-reg) cell-associated Th2 suppression [2]. Anergy is defined<br />

as the inability <strong>of</strong> antigen-specific cells to generate an allergic<br />

reaction to an antigen [3].<br />

IL-10 has a role in anergy as well as in immune suppression,<br />

whereas IL-4 plays a predominant role in allergy [3]. IL-10<br />

is produced mainly by Th2 cells, T-reg cells, monocytes, and<br />

B lymphocytes and, in small amounts, by Th1 cells. IL-10<br />

inhibits the proliferation <strong>of</strong> Th1 and Th2 cells in response to<br />

specific antigens. IL-10 also inhibits the production <strong>of</strong> gammainterferon<br />

(IFN-γ) and IL-2 by Th1 cells; the production <strong>of</strong><br />

IL-4 and IL-5 by Th2 cells; the production <strong>of</strong> IL-6, IL-8, IL-<br />

12, TNF-α, and IL-1β by mononuclear phagocytes; and the<br />

production <strong>of</strong> TNF-α and IFN-γ by natural killer cells. It<br />

further inhibits monocytes [3,4,5]. Therefore, IL-10 is known<br />

as a strongly inhibitory cytokine. IL-10 causes differentiation<br />

<strong>of</strong> T-reg cells from T helper cells. T-reg cells secrete IL-10,<br />

IFN-γ, TGF-β, and IL-5 [3]. T-reg cells also suppress functions<br />

<strong>of</strong> Th1 and Th2 cells [6]. Secretion <strong>of</strong> IL-4 by the Th2 pathway<br />

induces allergy. Desensitization treatments can be done if an<br />

allergic patient is chronically treated with a related allergen at<br />

a low dose. Allergic individuals develop anergy via IL-10.<br />

We hypothesized that chronic stimulation by environmental<br />

agents triggers the Th2 pathway and anergy. The Th2 pathway<br />

is shifted from IL-4 to IL-10 in anergy. It is well known that<br />

high IL-10 triggers the differentiation <strong>of</strong> T-reg cells from T<br />

helper cells. Once T-reg cells are increased, these cells will<br />

start to inhibit functions <strong>of</strong> Th2 and Th1 cells and start to<br />

secrete their own IL-10. In addition, if high levels <strong>of</strong> IL-10<br />

persist, it causes serious immune suppression. Therefore, we<br />

examined the relationships between prognostic markers in<br />

NHL and components <strong>of</strong> the Th2 pathway, such as IL-10, IL-<br />

4, IgE, and eosinophils. Figure 1 illustrates our hypothesis.<br />

Materials and Methods<br />

Thirty-one newly diagnosed NHL patients and 27 healthy<br />

controls were enrolled. The median ages <strong>of</strong> patients and<br />

controls were 64 (range: 19-85) and 26 (range: 23-60) years,<br />

respectively. All participants were free <strong>of</strong> history <strong>of</strong> allergy,<br />

dermatitis, or parasites in stool samples, because allergies<br />

and parasites can trigger the Th2 pathway and could cause<br />

misleading results.<br />

Twenty-seven patients had diffuse large B cell lymphoma<br />

(DLBCL) and 4 patients had T-cell lymphoma. The<br />

characteristics <strong>of</strong> the patients are given in Table 1.<br />

Initial blood samples were collected to test IL-4, IL-10,<br />

and IgE levels. Patient pretreatment values for eosinophils,<br />

hemoglobin, lymphocytes, lactate dehydrogenase (LDH),<br />

C-reactive protein (CRP), sedimentation, b2 microglobulin,<br />

and albumin were collected from the patient records. A second<br />

blood sample for IL-4 and IL-10 was collected from only the<br />

patients after completion <strong>of</strong> the 4 cycles <strong>of</strong> chemotherapy. The<br />

chemotherapy regimens were decided by their physicians. The<br />

blood samples for IL-10 and IL-4 were collected into tubes<br />

with no anticoagulant. The samples were centrifuged within<br />

2 h at 4000 rpm for 10 min, and the serum was separated and<br />

kept at -80 °C.<br />

The IL-4 and IL-10 concentrations were analyzed from<br />

serum samples using the enzyme amplified sensitivity<br />

immunoassay (EASIA) method in accordance with<br />

the instructions <strong>of</strong> the kit’s manufacturer (DIAsource<br />

ImmunoAssays, Cat. No. KAP1281 and KAP1321, Belgium).<br />

These IL-4 and IL-10 assays are specific for endogenous<br />

human IL-4 and IL-10, respectively. The samples were<br />

processed in duplicate. The detection limits <strong>of</strong> the kits for<br />

IL-4 and IL-10 are 1.2 pg/mL and 1.6 pg/mL, respectively. The<br />

intraassay and interassay variation <strong>of</strong> the IL-4 kit was 3.8%<br />

and 4.5%, respectively. The intraassay and interassay variation<br />

<strong>of</strong> the IL-10 kit was 2.8% and 2.8%, respectively. The results<br />

are presented in pg/mL.<br />

The Eastern Cooperative Oncology Group (ECOG)<br />

performance status system and the Ann Arbor staging system<br />

were used. International Prognostic Index (IPI) scores were<br />

categorized as low risk (scores 0-2) or high risk (scores 3-5).<br />

T-cell lymphoma patients were treated with CHOP<br />

(cyclophosphamide, doxorubicin, vincristine, and prednisone)<br />

chemotherapy. DLBCL patients were treated with rituximab<br />

plus CHOP.<br />

Overall survival (OS) was determined as the time between<br />

the diagnosis <strong>of</strong> lymphoma and the last evaluation in the<br />

hospital or death for any reason during the study.<br />

The university’s local ethics committee approved this<br />

study and all participants gave informed consent. This study<br />

is in accordance with the Helsinki Declaration <strong>of</strong> 1975.<br />

Statistical Analysis<br />

Statistical analyses were performed using SPSS 15.0.<br />

The normality <strong>of</strong> distribution was checked by Kolmogorov-<br />

Smirnov test. For variables not confirming to normal<br />

distribution comparisons were analyzed with the Mann-<br />

Whitney U-test. The Wilcoxon signed-rank test, Kruskal-<br />

Wallis test, Spearman test, Pearson chi-square test, and Fisher<br />

exact test were also used. Statistical significance was accepted<br />

at p8.24 and<br />

IL-4 <strong>of</strong> >43.05 (4 patients); group 4, IL-10 <strong>of</strong> >8.24 and IL-4 <strong>of</strong><br />

≤43.05 (11 patients). Because it only included a single patient,<br />

group 1 was not evaluated. We did not observe a significant<br />

difference between groups 2 and 3 with respect to albumin<br />

(p=0.548), while there was a difference between groups 2<br />

and 4 (p=0.005) and between groups 3 and 4 (p=0.026). The<br />

significant difference between groups 3 and 4 was noteworthy<br />

because both <strong>of</strong> these groups consisted <strong>of</strong> patients with high<br />

IL-10. However, IL-4 was higher in group 3 and lower in group<br />

4. The highest albumin values were observed in group 3. As<br />

mentioned above, there was a negative correlation between IL-<br />

10 levels and albumin in the entire patient sample (r=-0.46,<br />

p=0.01). Despite the high IL-10 level, albumin levels were<br />

high in group 3.<br />

The lack <strong>of</strong> a difference between group 2 and group 3 was<br />

also important. IL-10 levels were low in group 2. The albumin<br />

values in group 3 did not differ from those <strong>of</strong> group 2 despite<br />

high IL-10 levels. These results suggest that IL-4 alleviates or<br />

restores the repressive effects <strong>of</strong> IL-10 on albumin (Figure 2).<br />

Seven <strong>of</strong> 15 patients with high IL-10 (46%) and 4 <strong>of</strong> 16<br />

patients with low IL-10 (25%) died during the follow-up for a<br />

total number <strong>of</strong> 11 deceased patients. Ten <strong>of</strong> these 11 patients<br />

died before the completion <strong>of</strong> the fourth cycle <strong>of</strong> chemotherapy.<br />

Our mean observation period was 281.44 days (range: 19-<br />

402). The minimum observation time in living patients was<br />

112 days. Therefore, we relied on short-time surveying.<br />

The highest IL-10 value in living patients was 107.1 pg/<br />

mL, 13-fold higher than the cut-<strong>of</strong>f value. This value was<br />

found in patient number 21. This patient also exhibited a very<br />

high IL-4 value <strong>of</strong> 2081 pg/mL, 48-fold higher than the cut-<strong>of</strong>f<br />

value.<br />

For survival analysis, the patients were classified into 3<br />

groups according to the cut-<strong>of</strong>f value (8.24 pg/mL) and the<br />

highest value (107 pg/mL) in living patients: Group A, IL-10 <strong>of</strong><br />

≤8.24 (16 patients); group B, 8.24 < IL-10 ≤107 (11 patients);<br />

and group C, IL-10 <strong>of</strong> >107 (4 patients). The Kaplan-Meier test<br />

and log rank analysis were performed for the survival analysis.<br />

The mean survival times were 323 days in group A, 285<br />

days in group B, and 38.7 days in group C. The differences<br />

were statistically significant (p=08.24; 15 patients). Lymphocyte counts were<br />

decreased in the latter group (p=0.002).<br />

Differences in the relationships between IL-4 and age, CRP,<br />

hemoglobin, extranodal involvement, ECOG performance,<br />

stage, lymphopenia, LDH, lymphoid tissue size, IPI score, ≥2<br />

microglobulin, or B symptoms were not observed.<br />

The characteristics <strong>of</strong> patients with T-cell lymphoma are<br />

shown in Table 2.<br />

Discussion<br />

In this study, high IL-10 levels were correlated with several<br />

poor prognostic features, including low albumin. However,<br />

IL-4 was positively correlated with albumin. In addition, IL-4<br />

was able to overcome the negative effects <strong>of</strong> IL-10 on albumin.<br />

To our knowledge, this is the first study to detect a positive<br />

relationship between IL-4 and albumin and the ability <strong>of</strong> IL-4<br />

to overcome the effects <strong>of</strong> IL-10 on albumin in NHL patients.<br />

IL-4 is an agent used in experimental treatment for<br />

NHL. The rationalization for this treatment is based on the<br />

observation <strong>of</strong> the inhibitory effect <strong>of</strong> IL-4 on NHL B cells and<br />

cancer cells in vitro [7,8].<br />

In the literature, IL-10 is generally connected to the poor<br />

prognostic factors <strong>of</strong> NHL. One <strong>of</strong> the most noteworthy<br />

relevant studies was performed by Blay et al. They observed<br />

detectable IL-10 levels in 46% <strong>of</strong> patients with active disease.<br />

Detectable IL-10 levels were related to very short survival [9].<br />

However, Cortes et al. could not observe a relationship with<br />

complete remission, failure-free survival, or OS. There was<br />

also no relationship between IL-10 and any prognostic factors<br />

except B symptoms [10].<br />

Lech-Maranda et al. observed a relationship between<br />

detectable IL-10 levels and age <strong>of</strong> >60, ECOG status <strong>of</strong> ≥2,<br />

advanced stage, bulky tumor mass, high LDH, high IPI score,<br />

≥2 microglobulin, anemia, existence <strong>of</strong> B symptoms, low<br />

albumin, low CR rate, and shorter progression-free survival<br />

and OS [11]. Nacinovic-Duletic et al. reported similar<br />

results. The patients with high IL-10 exhibited shorter<br />

survival [12]. However, Guney et al. observed only the<br />

relationship between IL-10 and high LDH and bone marrow<br />

involvement [13]. They detected significant decreases in IL-<br />

10 levels after chemotherapy. Fabre-Guillevin et al. did not<br />

find any relationship between IL-4 or IL-10 and complete<br />

remission, failure-free survival, or OS [14].<br />

As mentioned before, Lech-Maranda et al. observed a<br />

negative correlation between albumin and IL-10 [11]. Our<br />

finding was consistent with this result; in addition, we<br />

observed a positive effect <strong>of</strong> IL-4 on albumin.<br />

Lymphopenia is related to poor prognosis in many cancers<br />

[15,16]. In our study, the pretreatment lymphocyte count<br />

was negatively correlated with IL-10. To our knowledge,<br />

this is the first study in which lymphopenia was found to be<br />

related to high IL-10 levels in NHL. Some researchers have<br />

observed this relationship in sepsis [17,18].<br />

We cannot define the source <strong>of</strong> high IL-10 levels in our<br />

study; it could be Th2, T-reg, or tumor cells. According to<br />

our hypothesis, NHL pathogenesis starts with Th2 pathway<br />

activation. We know that the increased secretion <strong>of</strong> IL-10 by<br />

Th2 cells can promote the development <strong>of</strong> T-reg cells from T<br />

helper cells, and newly developed T-reg cells begin to secrete<br />

their own IL-10 and inhibit both Th1 and Th2 functions [3,6].<br />

As mentioned above, IL-10 is a strong inhibitor cytokine. In<br />

situations <strong>of</strong> very highly increased IL-10 levels, the inhibitor<br />

effect <strong>of</strong> IL-10 will be particularly enormous and will result<br />

in strong inhibition <strong>of</strong> Th1 and Th2 cell function. With the<br />

suppressive effect <strong>of</strong> IL-10, Th2 cannot produce IL-4. Our<br />

interpretation <strong>of</strong> the increase in IL-4 that was observed in<br />

some patients (5 patients with increased pretreatment IL-4<br />

and 3 with increased posttreatment IL-4 values) is that<br />

there may be remnant Th2 pathway activation, which could<br />

have escaped the suppressive effect <strong>of</strong> IL-10. It is hard to<br />

show the initial activity <strong>of</strong> Th2 cells at the time <strong>of</strong> disease<br />

development because we are most likely catching patients<br />

after the switching <strong>of</strong> Th2 cell activity to increased T-reg cell<br />

activity and at a point when the disease is well established.<br />

To our knowledge, this is the first study to investigate the<br />

place <strong>of</strong> the Th2 pathway in NHL through the components<br />

<strong>of</strong> Th2 by detection <strong>of</strong> IgE, eosinophils, IL-10, and IL-4.<br />

IL-10 was related to very early death in this study.<br />

Therefore, we think that other treatment options may be<br />

more effective for patients with very high IL-10, such as anti-<br />

IL-10 antibody in addition to CHOP. However, one could<br />

also make a different comment: if an increasing IL-10 level is<br />

accompanying NHL, the increased IL-10 may be a reaction<br />

<strong>of</strong> the immune system, and supporting this reaction may<br />

help to control the aggression <strong>of</strong> lymphoma.<br />

Abstract:<br />

Objective: Multiple myeloma (MM) is a B-cell malignancy characterized by the clonal proliferation <strong>of</strong> malignant plasma cells.<br />

According to results <strong>of</strong> some studies, it has been suggested that the HLA class 1 and 2 genes have susceptibility effects on MM.<br />

Studies <strong>of</strong> different populations have reported different HLA class 1 and 2 alleles that affect MM. In this study, we assessed<br />

the association <strong>of</strong> HLA class 1 and class 2 antigens with MM in Iranian patients.<br />

Materials and Methods: We performed a case-control genotyping study with 105 Iranian MM patients that were selected<br />

from the bone marrow transplantation department <strong>of</strong> Taleghani Hospital and 150 controls using single specific primerpolymerase<br />

chain reaction with the HLA-Ready Gene ABDR Kit.<br />

Results: Our results demonstrated that 21% <strong>of</strong> patients versus 12% <strong>of</strong> controls and 11% <strong>of</strong> patients versus 3% <strong>of</strong> controls<br />

carried HLA-A*03 and HLA-B*18, respectively. The MM patients had a significant increase in the frequency <strong>of</strong> HLA-A*03 and<br />

HLA-B*18 alleles in comparison to control subjects (p=0.039, OR=2.057 and p=0.013, OR=3.567, respectively).<br />

Conclusion: Our findings suggested that the HLA-A*03 and HLA-B*18 alleles have significant susceptibility effects on MM<br />

in the Iranian population. However, compared to other populations, the above-mentioned alleles had different statuses. Since<br />

there are not many studies evaluating and calculating this association among ethnic groups, further studies among other<br />

populations are needed to explain the exact association <strong>of</strong> the HLA genes with MM.<br />

Key Words: Multiple myeloma, HLA-A, HLA-B, HLA-DRB1, Genetic susceptibility<br />

Farklı popülasyonlarda yapılan çalışmalarda, farklı HLA sınıf 1 ve 2 allellerinin MM üzerine etkisi olduğu bildirilmiştir. Bu<br />

çalışmada, İranlı MM hastalarında HLA sınıf 1 ve sınıf 2 antijenlerinin birlikteliğini değerlendirdik.<br />

Gereç ve Yöntemler: HLA-Ready Gene ABDR kitleriyle tekli spesifik primer polimeraz zincir reaksiyonu yönteminin<br />

kullanıldığı bu olgu-kontrol genetiplendirme çalışmasında, hasta grubuna Taleghani Hastanesi kemik iliği nakli bölümünden<br />

seçilen 105 İranlı MM hastası ve 150 de kontrol olgusu dahil edilmiştir.<br />

Bulgular: Çalışma sonucunda, HLA-A*03 hasta grubunda %21 ve kontrol grubunda %12 bulunurken, HLA-B*18 ise hasta<br />

grubunda %11 ve kontrol grubunda %3 olarak saptanmıştır. MM hastalarının HLA-A*03 ve HLA-B*18 allele sahip olma oranı<br />

kontrol olgularıyla karşılaştırıldığında istatistiki olarak anlamlı olacak şekilde yüksek bulunmuştur (p=0,039, OR=2,057 ve<br />

p=0,013, OR=3,567, sırasıyla).<br />

Sonuç: Bizim bulgularımız, İran toplumunda HLA-A*03 ve HLA-B*18 allel varlığının istatistiki olarak anlamlı olacak şekilde<br />

MM’ye yatkınlık yarattığını ortaya koymaktadır. Bununla birlikte, diğer toplumlara bakıldığında adı geçen allellerin aynı sonucu<br />

Introduction<br />

Multiple myeloma (MM) is a B-cell malignancy<br />

characterized by the clonal proliferation <strong>of</strong> malignant<br />

plasma cells, and evidence indicates that the bone marrow<br />

microenvironments <strong>of</strong> tumor cells have a crucial role in<br />

myeloma pathogenesis [1]. Neurological and impaired<br />

hemopoiesis symptoms, bone complications, renal failure,<br />

and infection are some <strong>of</strong> the heterogeneous clinical features<br />

[2]. MM is the second most prevalent blood cancer after non-<br />

Hodgkin lymphoma [3]. MM represents approximately 1% <strong>of</strong><br />

all cancers, 2% <strong>of</strong> all cancer deaths, and 10% <strong>of</strong> hematological<br />

malignancies. The prevalence <strong>of</strong> MM varies among different<br />

populations. Blacks have a 2-fold higher incidence than<br />

whites, while the Japanese, Chinese, and South Koreans<br />

have the lowest incidence [4,5]. Although the exact etiology<br />

<strong>of</strong> MM is unknown, the genetic factor has an important<br />

effect on it. Simply, MM is a condition characterized by the<br />

unlimited proliferation <strong>of</strong> plasma cells. Since the HLA genes<br />

are associated with a variety <strong>of</strong> immunologic diseases, they<br />

may be involved as a crucial factor in MM [6]. In 1970 for<br />

the first time, after recognition <strong>of</strong> HLA class 1 and prior to<br />

identification <strong>of</strong> HLA class 2, the susceptibility effects <strong>of</strong><br />

HLA genes on MM were studied [7,8,9,10,11,12]. Not many<br />

studies have taken sufficient account <strong>of</strong> the effect <strong>of</strong> HLA<br />

genes on the susceptibility to MM in different populations.<br />

These studies reported different susceptible or protective<br />

alleles <strong>of</strong> HLA genes in association with MM. Some studies<br />

indicated no significant association between HLA-A and<br />

-B genes and MM, while other studies demonstrated that<br />

HLA-A3, -B18, -Bw65, and -DRw14 had associations with<br />

MM [13,14,15]. In the present study, for the first time, the<br />

associations <strong>of</strong> HLA class 1 and 2 genes with MM in Iranian<br />

patients were investigated.<br />

Materials and Methods<br />

Patients and Controls<br />

One hundred and five Iranian patients were selected from<br />

the bone marrow transplantation department <strong>of</strong> Taleghani<br />

Hospital. The diagnosis <strong>of</strong> MM was made by an oncologist.<br />

Additionally, one hundred and twenty ethnically, age-, and<br />

sex-matched healthy individuals without personal or familial<br />

history <strong>of</strong> cancer or autoimmune disorders were included as<br />

controls. The subjects gave informed consent to participate.<br />

DNA Extraction and HLA Genotyping<br />

Genomic DNA from venous peripheral blood samples was<br />

extracted by the salting-out method [16]. HLA typing was<br />

performed at the Tehran Medical Genetics Laboratory. HLA-A,<br />

-B, and -DRB1 genotyping was carried out based on lowresolution<br />

single specific primer-polymerase chain reaction<br />

(SSP-PCR) HLA typing with the HLA-Ready Gene ABDR Kit<br />

(Inno-Train Diagnostik GmbH, Germany) according to the<br />

manufacturer’s recommendation. The PCR products were run<br />

on 2% agarose gel.<br />

Statistical Analysis<br />

By using chi-square and Fisher exact tests, comparisons<br />

between HLA-A, -B, and -DRB1 alleles <strong>of</strong> MM patients and<br />

the controls were performed. SPSS 18.0 for Windows was<br />

used for analysis and p

-DRB1 in MM patients and controls are demonstrated in Table<br />

2. As outlined in Table 2, no significant associations between<br />

HLA-DRB1 and MM were observed. Low-resolution HLA<br />

typing revealed that 21% <strong>of</strong> patients versus 12% <strong>of</strong> controls<br />

and 11% <strong>of</strong> patients versus 3% <strong>of</strong> controls carried HLA-A*03<br />

and HLA-B*18, respectively. The MM group had a significant<br />

increase in the frequency <strong>of</strong> HLA-A*03 and HLA-B*18 alleles<br />

in comparison to control subjects (p=0.039, OR=2.057 and<br />

p=0.013, OR=3.567, respectively) (Table 2).<br />

Discussion<br />

After description <strong>of</strong> a serological technique for HLA typing,<br />

studies on the association <strong>of</strong> the HLA genes with susceptibility<br />

to or protection against different disease were begun. In our<br />

research, for the first time, we investigated the association <strong>of</strong><br />

HLA class 1 and 2 genes with MM disease in Iranian patients.<br />

In our study, the HLA-A*03 and HLA-B*18 alleles had higher<br />

frequencies in MM patients than in control individuals and<br />

had significantly positive associations with MM. Therefore, the<br />

HLA-A*03 and HLA-B*18 alleles have a susceptibility effect in<br />

Iranian MM patients (p=0.039 and OR=2.057, p=0.013 and<br />

OR=3.567, respectively).<br />

Consistent with our results, in 2002, a study on 68 MM<br />

patients in southern Africa reported that the HLA-B*18 allele<br />

had an association (p

Abstract:<br />

Objective: Hepcidin plays a pivotal role in iron homeostasis. It is predominantly produced by hepatocytes and inhibits iron<br />

release from macrophages and iron uptake by intestinal epithelial cells. Competitive ELISA is the current method <strong>of</strong> choice<br />

for the quantification <strong>of</strong> serum hepcidin because <strong>of</strong> its lower detection limit, low costs, and high throughput. This study aims<br />

to discuss the role <strong>of</strong> hepcidin in the pathogenesis <strong>of</strong> iron overload in recently diagnosed myelodysplasia (MDS) cases.<br />

Materials and Methods: The study included 21 recently diagnosed MDS patients and 13 healthy controls. Ferritin,<br />

hepcidin, and soluble transferrin receptor (sTFR) were measured in all subjects.<br />

Results: There were 7 cases <strong>of</strong> hypocellular MDS, 8 cases <strong>of</strong> refractory cytopenia with multilineage dysplasia, and 6 cases<br />

<strong>of</strong> refractory anemia with excess blasts. No difference was observed among the 3 MDS subtypes in terms <strong>of</strong> hepcidin, sTFR,<br />

and ferritin levels (p>0.05). Mean hepcidin levels in the MDS and control groups were 55.8±21.5 ng/mL and 19.9±2.6 ng/<br />

mL, respectively. Mean sTFR was 45.7±8.8 nmol/L in MDS patients and <strong>31</strong>.1±5.6 nmol/L in the controls. Mean ferritin levels<br />

were significantly higher in MDS patients than in controls (539.14±83.5 ng/mL vs. 104.6±42.9 ng/mL, p0.05).<br />

Conclusion: Hepcidin may not be the main cause <strong>of</strong> iron overload in MDS. Further studies are required to test failure <strong>of</strong><br />

production or peripheral unresponsiveness to hepcidin in MDS cases.<br />

Key Words: Hepcidin, Myelodysplasia, Iron overload<br />

Özet:<br />

Amaç: Hepsidin demir dengesinde önemli bir rol oynar. Temel olarak hepatositler tarafından üretilir ve intestinal epitel<br />

hücrelerinden demir alımını ve makr<strong>of</strong>ajlardan demir salınımını inhibe eder. Kompetitif ELİZA en düşük düzeyleri<br />

saptayabilmesi, düşük maliyeti ve yüksek test kapasitesi ile kantitatif serum hepsidin miktari ölçümü için tercih edilen<br />

mevcut bir yöntemdir. Bu çalışmanın amacı son zamanlarda miyelodisplazi (MDS) tanısı almış olgularda demir yükünün<br />

patogenezinde hepsidinin rolünü tartışmaktır.<br />

Gereç ve Yöntemler: Bu çalışmaya 21 yeni tanı MDS hastası ve 13 sağlıklı kontrol alındı. Ferritin, hepsidin ve soluble<br />

transferrin reseptörü (sTFR) tüm olgularda ölçüldü.<br />

Bulgular: Hiposellüler MDS’li 7 olgu, multilineage displazili refrakter sitopenili 8 olgu ve artmış blastlı refrakter anemili 6 olgu<br />

vardı. Bu 3 MDS alt tipleri arasında hepsidin, sTFR ve ferritin düzeyleri açısından fark gözlenmedi (p>0,05). Ortalama hepsidin<br />

seviyesi sırasıyla MDS grubunda 55,8±21,5 ng/mL ve kontrol grubunda ise 19,9±2,6 ng/mL idi. Ortalama sTFR, MDS grubunda<br />

45,7±8,8 nmol/L ve kontrol grubunda ise <strong>31</strong>,1±5,6 nmol/L idi. Ortalama ferritin seviyeleri ise MDS grubunda kontrolden anlamlı<br />

olarak yüksekti (539,14±83,5 ng/mL vs. 104,6±42,9 ng/mL, p0,05).<br />

Sonuç: Hepsidin MDS’de aşırı demir yükünün ana nedeni olmayabilir. MDS’li olgularda hepsidine çevresel yanıtsızlık veya<br />

üretimi yetersizliğini test edecek başka çalışmalara ihtiyaç vardır.<br />

Introduction<br />

Myelodysplastic syndrome (MDS) is a group <strong>of</strong><br />

clonal hemopoietic disorders characterized by ineffective<br />

hematopoiesis, bone marrow dysplasia, and an increased risk <strong>of</strong><br />

transformation to acute myeloid leukemia. The large majority<br />

<strong>of</strong> patients with MDS are anemic and eventually up to 90% <strong>of</strong><br />

them require regular transfusions. In 50% to 60% <strong>of</strong> patients,<br />

anemia is severe, with hemoglobin levels below 10 g/dL [1].<br />

The liver polypeptide hepcidin plays a pivotal role in iron<br />

homeostasis. In macrophages, it accelerates the degradation<br />

<strong>of</strong> the trans-membrane iron exporter ferroportin mRNA.<br />

In intestinal epithelial cells, it is believed to down-regulate<br />

divalent metal transporter-1, which is involved in the transfer<br />

<strong>of</strong> iron across the intestinal wall [2].<br />

Previous reports on hepcidin levels in MDS showed<br />

conflicting results. Murphy et al. found that urinary excretion<br />

<strong>of</strong> hepcidin was lower in MDS in comparison to the control<br />

group and interpreted this finding as evidence for hepcidin’s<br />

role in iron overload in MDS [3]. However, others reported<br />

contrary findings [4]. In an earlier study, we measured prohepcidin<br />

in MDS and found it to be significantly lower in<br />

comparison to levels in the control group [5]. However, the<br />

utility <strong>of</strong> the prohepcidin assay is controversial [6].<br />

The development <strong>of</strong> quantification techniques based<br />

on mass spectrometry [matrix-assisted laser desorption<br />

ionization, surface enhanced laser desorption/ionization<br />

time-<strong>of</strong>-flight mass spectrometry (SELDI-TOF MS), or liquid<br />

chromatography tandem mass spectrometry] has shown<br />

promising results. However, some <strong>of</strong> these approaches did<br />

not use internal standards for the quantification <strong>of</strong> hepcidin<br />

and are considered semi-quantitative; moreover they require<br />

specialized equipment that is not widely accessible [7].<br />

Regarding MDS, there are only a few conflicting data about<br />

urinary hepcidin measured by using first generation semiquantitative<br />

techniques [8]. The competitive enzyme-linked<br />

immunosorbent assay (ELISA) is currently the method <strong>of</strong><br />

choice for the quantification <strong>of</strong> serum hepcidin because <strong>of</strong> its<br />

lower detection limit, low costs, and high throughput [6].<br />

Although prolonged red blood cell transfusion therapy<br />

appears to be the main contributor to iron overload in MDS,<br />

many patients appear to develop iron overload at an early<br />

stage <strong>of</strong> the disease, before the onset <strong>of</strong> transfusions. It has<br />

been postulated that an altered production <strong>of</strong> hepcidin, the<br />

recently discovered key hormone regulating iron homeostasis,<br />

may play a role in this regard [8].<br />

The aim <strong>of</strong> this study was to find out whether hepcidin<br />

plays a key role in the pathogenesis <strong>of</strong> iron overload seen<br />

in recently diagnosed MDS, or whether hepcidin levels are<br />

just a consequence <strong>of</strong> the interaction between ineffective<br />

erythropoiesis and blood transfusion.<br />

Materials and Methods<br />

This study included 21 MDS patients recently diagnosed in<br />

the Clinical <strong>Hematology</strong> Unit <strong>of</strong> Cairo University. All patients<br />

who had an MDS diagnosis <strong>of</strong> less than 6 months entered the<br />

study if they were not on iron chelation, had no evidence <strong>of</strong><br />

infection and no renal or liver impairment, and did not receive<br />

more than 10 units <strong>of</strong> blood. Ethical committee approval <strong>of</strong><br />

the study was obtained. Each individual in the study signed a<br />

consent form.<br />

Five milliliters <strong>of</strong> venous blood was obtained from each<br />

individual in the study after at least 8 h <strong>of</strong> fasting. For MDS<br />

patients, samples were taken at least 5 days after the last<br />

transfusion to avoid acute alterations in the hepcidin level.<br />

The samples were centrifuged at 3000 rpm for 10 min to<br />

separate sera and stored at -80 °C until analyzed.<br />

Serum levels <strong>of</strong> hepcidin were determined using a<br />

commercially available ELISA kit (DRG Instruments GmbH,<br />

Marburg, Germany) according to the manufacturer’s protocol.<br />

The 5% to 95% range in apparently normal, healthy adults is<br />

between 13.3 and 54.4 ng/mL.<br />

Soluble transferrin receptor (sTFR) concentrations<br />

were measured in serum, stored at -80 °C, with the use <strong>of</strong><br />

a commercially available ELISA kit (Quantikine IVD Soluble<br />

Transferrin Receptor ELISA; R&D Systems Europe Ltd.,<br />

Abingdon, UK). The reference interval is 8.7-28.1 nmol/L.<br />

Serum ferritin was quantified using the DRG ferritin kit<br />

(ELISA) kit (EIA-1872; DRG International Inc., Mountainside,<br />

NJ, USA). The reference interval in healthy males and females<br />

is 20-250 ng/mL and 10-120 ng/mL, respectively.<br />

Statistics Analysis<br />

SPSS 17 was used for descriptive analysis and comparisons.<br />

Spearman’s test was used for correlation analysis and<br />

analysis <strong>of</strong> variance (ANOVA) was used for the comparison<br />

<strong>of</strong> multiple parameters among different groups. Differences<br />

and correlations were considered significant when p0.05, Table<br />

3). Mean hepcidin/ferritin ratio in patients with MDS was<br />

higher than in the controls (0.48±1.2 vs. 0.32±0.19), but this<br />

was not statistically significant (p=0.6).<br />

Discussion<br />

It has been reported that ineffective erythropoiesis<br />

enhances iron absorption in MDS through down-regulation<br />

<strong>of</strong> hepcidin and its prohormone such that serum ferritin rises<br />

to 500-600 ng/mL but seldom exceeds these values before<br />

transfusion begins [9,10]. Moreover, MDS is characterized<br />

by iron overload secondary to blood transfusion. However,<br />

its impact on stimulation <strong>of</strong> pro-hepcidin release to inhibit<br />

iron absorption is less than the erythroid drive suppressing its<br />

release, as shown from our earlier results [5].<br />

In this work, we included newly diagnosed (within 6<br />

months <strong>of</strong> diagnosis) MDS cases to limit the impact <strong>of</strong> overtransfusion<br />

on hepcidin levels. Furthermore, blood samples<br />

were drawn at least 5 days after the last transfusion to abolish<br />

the effect <strong>of</strong> acute transfusion on hepcidin expression.<br />

We found hepcidin levels higher in MDS cases in<br />

comparison to the control group, but this difference was not<br />

statistically significant, which could be attributed to the small<br />

number <strong>of</strong> patients studied.<br />

Our results are in line with those <strong>of</strong> Qin et al., who found<br />

that both hepcidin and serum ferritin levels in MDS patients,<br />

regardless <strong>of</strong> transfusion dependency or the number <strong>of</strong> blood<br />

transfusions, were higher than those <strong>of</strong> healthy controls<br />

[11]. Our findings suggest that iron overload is not related<br />

to defective hepcidin release but is rather associated with<br />

ineffective erythropoiesis and blood transfusion.<br />

In another study using SELDI-TOF MS for hepcidin assay,<br />

serum hepcidin levels were measured to be slightly higher in<br />

MDS patients than in controls, but this difference did not reach<br />

statistical significance. Nevertheless, the hepcidin/ferritin<br />

ratio was significantly lower for the whole MDS population<br />

as compared to the controls, which is not consistent with our<br />

study in which the ratio was higher in MDS cases [8]. This<br />

could be explained by the higher mean ferritin levels <strong>of</strong> the<br />

MDS population in that study, which also included heavily<br />

transfused cases.<br />

Ganz et al. reported that serum hepcidin was high in<br />

low-grade MDS patients in correlation with their iron and<br />

oxidative status, and that it was further increased by treatment<br />

with deferasirox. They concluded that the hepcidin level<br />

represented a balance between the stimulating effect <strong>of</strong> iron<br />

overload and the inhibitory effects <strong>of</strong> erythropoietic activity<br />

and oxidative stress. These preliminary findings favor the<br />

rationale for iron chelation therapy in such patients [12]. Our<br />

results revealed no correlation between hepcidin level and<br />

ferritin in patients with MDS in the context <strong>of</strong> non-heavily<br />

transfused patients.<br />

Qin et al. worked on heavily transfused MDS and found<br />

that the increase <strong>of</strong> hepcidin was not in synchrony with<br />

the increase in serum ferritin levels secondary to blood<br />

transfusion when the number <strong>of</strong> blood transfusions exceeded<br />

24 U. Hepcidin levels showed a negative relationship to serum<br />

ferritin, reflecting the decreased ability <strong>of</strong> hepcidin to inhibit<br />

body iron absorption during the increase <strong>of</strong> blood transfusion,<br />

which finally led to iron overload. Dynamic monitoring<br />

<strong>of</strong> the hepcidin concentration could help in predicting the<br />

occurrence <strong>of</strong> iron overload in transfusion-dependent MDS<br />

patients [11].<br />

The current data may indicate that there is no correlation<br />

between hepcidin and serum ferritin in MDS cases, and thus<br />

hepcidin may not be a main player in iron overload in MDS.<br />

A possibility <strong>of</strong> peripheral unresponsiveness to hepcidin in<br />

MDS or failure <strong>of</strong> production may be the underlying cause,<br />

but further studies are required.<br />

When divided into RCMD, RAEB, and hypoplastic MDS<br />

groups, the highest levels <strong>of</strong> hepcidin were in the RAEB group,<br />

indicating marked activity in the bone marrow, followed by<br />

the RCMD and the hypocellular MDS groups. However, the<br />

difference among different subgroups in terms <strong>of</strong> hepcidin,<br />

ferritin, or sTFR level did not reach statistical significance.<br />

Santini et al. found that mean hepcidin levels were<br />

consistently heterogeneous across different MDS subtypes,<br />

with the lowest levels in refractory anemia with ringed<br />

sideroblasts (1.43 nmol/L) and the highest in the RAEB (11.3<br />

nmol/L) (p=0.003) [8].<br />

Conclusion<br />

Iron overload in MDS involves many players. Further<br />

studies are required to reveal the causes <strong>of</strong> failure in<br />

erythropoiesis or the peripheral unresponsiveness to hepcidin<br />

in MDS cases.<br />

Belen FB, et al: Myelotoxicity with TPMT *3A/*3C Polymorphisms<br />

Introduction<br />

Myelosuppression is a serious complication <strong>of</strong><br />

chemotherapy in children with acute lymphoblastic leukemia<br />

(ALL). The duration and the severity <strong>of</strong> myelosuppression vary<br />

with genetic polymorphisms affecting drug pharmacokinetics<br />

and bone marrow failure syndromes [1,2]. The thiopurine<br />

S-methyl transferase (TPMT) enzyme is involved in the<br />

metabolism <strong>of</strong> 6-mercaptopurine (MP), a widely used<br />

cytostatic agent in childhood ALL. The levels <strong>of</strong> active MP<br />

metabolites are elevated during MP therapy in patients who<br />

carry TPMT mutations with decreased enzyme activity such<br />

as TPMT *2 (G238C), TPMT *3A (G460A and A719G),<br />

and TPMT *3C (A719G), leading to excessive bone marrow<br />

toxicity and being more pr<strong>of</strong>ound in those with 2 as compared<br />

to 1 nonfunctional allele [2,3,4,5,6]. The contribution <strong>of</strong><br />

methylenetetrahydr<strong>of</strong>olate reductase (MTHFR) mutations in<br />

MP-induced myelosuppression has not been well established<br />

[7,8]. We here describe the case <strong>of</strong> a 15-year-old girl with<br />

ALL and TPMT *3A/*3C and MTHFR polymorphisms who<br />

suffered from severe bone marrow suppression persisting<br />

during the consolidation and maintenance therapy.<br />

Case Presentation<br />

A 15-year-old girl presented with a white blood cell<br />

(WBC) count <strong>of</strong> 150x109/L, anemia, thrombocytopenia,<br />

and mediastinal enlargement. A diagnosis <strong>of</strong> T-cell ALL<br />

was made based on peripheral blood morphology and<br />

immunophenotyping by flow cytometer. Karyotyping<br />

disclosed t(11;14), but polymerase chain reaction (PCR) tests<br />

for t(4;11) and t(9;21) were negative. She was treated with<br />

the Berlin-Frankfurt-Münster (BFM) ALL-95 chemotherapy<br />

protocol [9]. She received induction chemotherapy<br />

uneventfully and achieved complete remission on day 33 with<br />

full bone marrow recovery. Five days after receiving the first<br />

5 days <strong>of</strong> Protocol Ib, which contained 6-MP at 60 mg/m 2 per<br />

day orally, cytosine arabinoside (c-ARA) at 75 mg/m 2 /day for<br />

4 doses, and a single dose <strong>of</strong> 1000 mg/m 2 cyclophosphamide,<br />

her WBC count, absolute neutrophil count (ANC), platelet<br />

count, and hemoglobin (Hb) level began to decrease and<br />

reached a minimum at week 14 (WBC: 0.8x10 9 /L, ANC<br />

:0x109/L; platelets: 3x10 9 /L; Hb: 5 g/dL). Chemotherapy was<br />

stopped; granulocyte colony-stimulating factor (G-CSF) was<br />

started at 5 µg/kg/day and increased to 10 µg/kg/day. Six weeks<br />

later, WBC and ANC returned to normal but Hb level and<br />

platelet count remained low. Bone marrow aspirations yielded<br />

dry taps. TPMT genotyping for G238C, G460A, and A719G<br />

was reported as negative. As WBC and ANC were within<br />

normal limits, chemotherapy was restarted, but her counts<br />

rapidly dropped (Figure 1). She remained pancytopenic for<br />

a further 6-week period, during which chemotherapy was<br />

stopped, and numerous platelet and erythrocyte transfusions<br />

were given. Bone marrow biopsy showed cellularity <strong>of</strong> 5%<br />

with no residual leukemia and/or fibrosis. PCR analysis for<br />

parvovirus B19, Epstein-Barr virus, and cytomegalovirus<br />

and the diepoxybutane (DEB) test were negative. Because<br />

<strong>of</strong> protracted pancytopenia, the rest <strong>of</strong> Protocol Ib and<br />

intensification blocks were omitted and maintenance therapy<br />

with oral 6-MP and methotrexate (MTX) was started at<br />

25% <strong>of</strong> protocol doses. Absolute neutrophil count dropped<br />

and remained below 0.8x109/mm 3 despite G-CSF therapy.<br />

Genotyping for MTHFR revealed heterozygousity for C677T<br />

and A1298C polymorphisms. We were informed that the<br />

patient had TPMT *3A/*3C polymorphisms; the previous<br />

report <strong>of</strong> wild-type TPMT was a transcription error. The doses<br />

<strong>of</strong> 6-MP and MTX were reduced to 10% <strong>of</strong> protocol doses, but<br />

the patient remained severely pancytopenic and transfusiondependent.<br />

Bone marrow biopsy showed pr<strong>of</strong>ound<br />

hypocellularity with occasional hematopoietic hot points and<br />

abundant fat cells, resembling aplastic anemia. Chemotherapy<br />

was stopped and oral prednisolone was started at a dose <strong>of</strong> 60<br />

mg/m 2 per day. WBC and platelet counts increased gradually<br />

starting from the second week, and bone marrow aspirate<br />

became normocellular and free <strong>of</strong> leukemic blasts at the end <strong>of</strong><br />

30 days <strong>of</strong> steroid therapy. Bone marrow biopsy showed 40%<br />

cellularity without residual blasts. As blood counts returned to<br />

normal limits, intensification therapy with 4 blocks <strong>of</strong> MTX at<br />

5 g/m 2 /day and 6-MP at 2.5 mg/m 2 /day (5% <strong>of</strong> protocol dose)<br />

was given over the next 54 days. During this period, WBC<br />

count and ANC remained between 2 and 3x10 9 /L and platelet<br />

counts could be kept above 10x10 9 /L by weekly transfusions<br />

(Figure 1). MTX levels were calculated at 24, 36, 42, 48, and<br />

54 h after infusion <strong>of</strong> MTX as below the highest upper limit to<br />

give additional folinic acid rescue. Reinduction therapy with<br />

vincristine, dexamethasone, L-asparaginase, and doxorubicine<br />

caused pr<strong>of</strong>ound pancytopenia complicated with prolonged<br />

febrile episodes, severe hyperglycemia, and liver dysfunction.<br />

Therefore, the second part <strong>of</strong> the reinduction therapy was<br />

omitted, and maintenance therapy was restarted at 10% <strong>of</strong><br />

standard doses. She completed the 5-week maintenance<br />

therapy with 6-MP and MTX doses ranging from 5% to<br />

10% and from 8% to 16%, respectively. After termination <strong>of</strong><br />

maintenance chemotherapy, blood counts gradually increased<br />

and reached normal range within 3 months. Informed consent<br />

was obtained.<br />

Discussion and Review <strong>of</strong> the Literature<br />

Following intensive chemotherapy, blood counts recover<br />

within 2 to 4 weeks in most cases <strong>of</strong> ALL. Longer periods<br />

<strong>of</strong> bone marrow suppression are rare and can be caused by<br />

abnormalities <strong>of</strong> drug disposition pathways or congenital<br />

bone marrow failure syndromes with myelodysplasia. A<br />

clear relation with excessive bone marrow toxicity has<br />

been established only for thiopurine drugs and TPMT<br />

polymorphisms [1,2,3,4,5,6,10]. Patients homozygous or<br />

compound heterozygous for a nonfunctional TPMT allele<br />

develop pancytopenia 2 to 4 weeks after starting oral 6-MP<br />

and recover within 2-6 weeks [11,12]. The longest duration<br />

<strong>of</strong> pancytopenia was 137 days in an 8-year-old boy with ALL<br />

who was homozygous for TPMT *3A/*3A [13].<br />

Bone marrow suppression in the present case with TPMT<br />

*3A/*3C polymorphisms was more severe as compared to<br />

previously described patients with 2 nonfunctional TPMT<br />

alleles. Pancytopenia developed shortly after introduction<br />

<strong>of</strong> 6-MP and persisted during maintenance therapy,<br />

despite reducing both 6-MP and MTX doses to 5% to 10%.<br />

Interruption <strong>of</strong> chemotherapy for 6-8 weeks and G-CSF<br />

therapy resulted in ANC recovery initially without significant<br />

increase in Hb levels or platelet counts, but the duration <strong>of</strong><br />

bone marrow suppression was prolonged as 6-MP exposures<br />

increased, suggesting that myelotoxicity is dose-dependent.<br />

However, we did not investigate additional single nucleotide<br />

polymorphisms involved in thiopurine metabolism, such<br />

as inosine triphosphate pyrophosphatase, that might have<br />

been responsible for extreme bone marrow suppression in<br />

our patient [14]. She also had MTHFR C677T and A1298C<br />

polymorphisms, which cause reduced MTHFR activity,<br />

leading to decreased production <strong>of</strong> S-adenosylmethionine, a<br />

protector <strong>of</strong> the TPMT enzyme [15]. Karas-Kuzelicki et al.<br />

reported increased myelotoxicity in children with ALL who<br />

were heterozygous for at least one low-activity TPMT allele<br />

and for C677T and/or A1298C polymorphisms in the MTHFR<br />

gene [7]. In contrast, another study found lower frequency<br />

<strong>of</strong> severe myelotoxicity in pediatric ALL patients having<br />

both TPMT and C677T polymorphisms [8]. Interestingly,<br />

we did not observe excessive hematological toxicity during<br />

intensification therapy with high-dose (5 g/m2) MTX<br />

combined with low-dose MP (2.5% <strong>of</strong> protocol dose) in our<br />

patient, suggesting that compound heterozygosity for C677T<br />

and A1298C is not an additional risk factor for hematotoxicity<br />

in children with TPMT polymorphisms. An interesting finding<br />

in the present case is a quick bone marrow recovery induced<br />

by glucocorticoid therapy. Bone marrow cellularity increased<br />

from 5% at the beginning to 45% at the end <strong>of</strong> 4 weeks <strong>of</strong> 2<br />

mg/kg prednisolone administration. Although steroid therapy<br />

is effective in the treatment <strong>of</strong> immune-mediated bone marrow<br />

suppression, its role in chemotherapy-induced bone marrow<br />

hypoplasia has not been well studied. A short course <strong>of</strong> highdose<br />

methylprednisolone therapy was reported to increase<br />

CD34 (+) progenitor cells and shorten chemotherapy-induced<br />

neutropenia in children with leukemia [16,17]. The molecular<br />

mechanisms <strong>of</strong> steroid effects on bone marrow regeneration<br />

need to be illuminated.<br />

Children with Fanconi anemia (FA) may experience<br />

severe bone marrow toxicity with alkylating agents like<br />

cyclophosphamide and busulphan [2,18]. Cyclophosphamide<br />

causes chromosomal breaks in FA patients. A recent study<br />

showed that cyclophosphamide-specific interstrand DNA<br />

cross-links were increased 15-fold in FA patients compared<br />

to non-FA patients [19]. Our patient had received high-dose<br />

cyclophosphamide in addition to 6-MP one week before<br />

development <strong>of</strong> initial bone marrow hypoplasia. She had<br />

none <strong>of</strong> the main clinical or laboratory features <strong>of</strong> FA, such<br />

as congenital defects, developmental abnormalities, elevated<br />

HbF level, or increased chromosomal fragility. Patients with<br />

myelodysplasia also show delayed bone marrow recovery<br />

after chemotherapy. Several cases <strong>of</strong> T-cell ALL have been<br />

described in patients with myelodysplasia associated with<br />

germline RUNX-1 mutation or microdeletion <strong>of</strong> 21q22<br />

resulting in RUNX-1 deficiency [20]. The conventional<br />

karyotyping performed for our patient is not able to detect<br />

such a small deletion, but absence <strong>of</strong> thrombocytopenia<br />

Abstract:<br />

Intravascular large B-cell lymphoma (IVLBCL) is a very rare type <strong>of</strong> non-Hodgkin lymphoma, usually affecting elderly<br />

patients and characterized by selective infiltration <strong>of</strong> neoplastic cells within blood vessels’ lumina. IVLBCL diagnosed<br />

with prostatic involvement is extremely rare. We report a patient <strong>of</strong> 65 years old, having mostly neurological complaints<br />

but diagnosed with IVLBCL upon histopathological examination <strong>of</strong> transurethral prostate resection material, which<br />

revealed large neoplastic cell infiltration totally limited within the lumens <strong>of</strong> small vessels. By immunohistochemistry,<br />

neoplastic cell infiltration was positive with MUM1, bcl-6, and bcl-2 and negative with ALK1, CD10, and CD30, with<br />

a high Ki-67 proliferation index. CD34 and CD<strong>31</strong> staining showed expression in endothelial cells, highlighting the<br />

intravascular nature <strong>of</strong> neoplastic infiltrate. The patient unfortunately refused to receive treatment and died <strong>of</strong> the<br />

disease 8 months after the diagnosis. IVLBCL, though very rare, should be considered in differential diagnosis <strong>of</strong> all<br />

organ biopsies with intravascular infiltration. Further improvements in the understanding <strong>of</strong> the pathogenesis and<br />

biology <strong>of</strong> this rare type <strong>of</strong> lymphoma are mandatory.<br />

Özsan N, et al: Intravascular Large B Cell Lymphoma<br />

Introduction<br />

Intravascular large B-cell lymphoma (IVLBCL) is a very<br />

rare type <strong>of</strong> non-Hodgkin lymphoma and is characterized by<br />

selective infiltration <strong>of</strong> neoplastic cells within blood vessels’<br />

lumina. IVLBCL is an aggressive disease, usually affecting<br />

elderly patients with a poor prognosis [1].<br />

Prostatic involvement in IVLBCL is extremely rare and has<br />

been described in only a few case reports. We hereby report<br />

a 65-year-old male patient who presented with neurological<br />

symptoms and was diagnosed with IVLBCL based on<br />

transurethral prostate resection (p-TUR) material.<br />

Case Presentation<br />

A 65-year-old man was admitted to the hospital with<br />

complaints <strong>of</strong> cervical and back pain. His past history<br />

revealed no remarkable illnesses, and he had no evidence <strong>of</strong><br />

human immunodeficiency virus infection or other causes <strong>of</strong><br />

immunodeficiency.<br />

Cervical spine magnetic resonance (MR) imaging showed<br />

signs consistent with degenerative discopathies at multiple<br />

levels and an increase in signals at the level <strong>of</strong> the conus<br />

medullaris, consistent with myelitis. Informed consent was<br />

obtained.<br />

The patient also had complaints indicating lower urinary<br />

tract symptoms, such as difficulty in urinating.<br />

Laboratory findings showed an increase in lactate<br />

dehydrogenase (LDH) levels (682 U/L; reference scale: 240-<br />

480 U/L) and a mild decrease in platelet count (83,000/µL;<br />

reference range: 150,000-450,000/µL). The prostate-specific<br />

antigen (PSA) level was in normal limits (PSA: 2.37 ng/mL;<br />

reference range: 0.15). Ultrasonography revealed<br />

enlargement in prostatic dimensions <strong>of</strong> 41x40x36 mm in<br />

size. p-TUR with spinal anesthesia was performed. After the<br />

surgery, the patient developed paraplegia and urinary and<br />

fecal incontinence. Lumbar spine MR imaging done after the<br />

surgery revealed signs consistent with lumbar spondylolysis,<br />

degenerative changes at multiple levels, and an increase <strong>of</strong><br />

signals in the conus medullaris, which may reveal myelitis. He<br />

was then given prednisolone at 1 g/day for 10 days with the<br />

diagnosis <strong>of</strong> myelitis upon neurology consultation.<br />

Histopathological examination <strong>of</strong> the p-TUR specimen<br />

revealed large neoplastic cell infiltration totally limited within<br />

the lumens <strong>of</strong> small vessels in the stroma, while acinar and<br />

glandular structures were all benign.<br />

Immunohistochemical analysis was performed on<br />

paraffin-embedded tissue sections with an automated stainer<br />

(Ventana Benchmark XT, Ventana Medical Systems, Tucson,<br />

AZ, USA) according to protocol. A streptavidin-biotinperoxidase<br />

detection system with diaminobenzidine as a<br />

chromogen was used to visualize bound secondary antibodies.<br />

The intravascular neoplastic cells were positive for CD20 and<br />

negative for CD3 and pan-cytokeratin. The following panel<br />

<strong>of</strong> antibody testing was then performed: CD10, bcl-6, bcl-<br />

2, IRF4/MUM1, CD30, Ki-67, CD34, ALK, and CD<strong>31</strong>. The<br />

antibodies were scored as positive when >30% <strong>of</strong> tumor cells<br />

showed immunoexpression. Neoplastic cell infiltration was<br />

positive with MUM1, bcl-6, and bcl-2 and negative with ALK1,<br />

CD10, and CD30. The Ki-67 proliferation index was high,<br />

showing expression in about 90% <strong>of</strong> neoplastic large cells.<br />

CD34 and CD<strong>31</strong> stainings showed expression in endothelial<br />

cells, highlighting the intravascular nature <strong>of</strong> the neoplastic<br />

infiltrate. In situ hybridization analysis was also performed<br />

using oligonucleotides complementary to Epstein–Barr early<br />

RNA transcripts in tissue sections <strong>of</strong> paraffin-embedded tissue<br />

in the same automated stainer (Ventana Medical Systems),<br />

which revealed negative results. The immunohistochemical<br />

expressions (IRF4/MUM1 and bcl-6 positivity, with CD10<br />

negativity) revealed a non-germinal center B cell (non-GCB)<br />

phenotype when classified according to the Hans criteria [2].<br />

The patient was diagnosed with IVLBCL from the p-TUR<br />

material.<br />

The patient was hospitalized in the hematology department<br />

with a diagnosis <strong>of</strong> lymphoma. No enlarged superficial lymph<br />

nodes were found on physical examination. Positron emission<br />

tomography-computed tomography (PET-CT) showed an<br />

increase in fluorodeoxyglucose signals in both kidneys, which<br />

was interpreted as consistent with an inflammatory origin.<br />

Upper abdominal ultrasonography revealed mild splenomegaly<br />

(135 mm). The patient was given prednisolone at 1 g/day for<br />

10 days, when bone marrow biopsy was performed. Bone<br />

marrow biopsy revealed no infiltration <strong>of</strong> lymphoma from<br />

either morphology or immunohistochemistry. R-CHOP<br />

chemotherapy was planned, but the patient refused to receive<br />

therapy and was discharged at his request. He received no<br />

therapy for IVLBCL and died from the disease 8 months after<br />

the diagnosis.<br />

Discussion and Review <strong>of</strong> the Literature<br />

In the current World Health Organization classification <strong>of</strong><br />

hematopoietic neoplasms, IVLBCL is defined as a rare type<br />

<strong>of</strong> extranodal large B-cell lymphoma characterized by the<br />

selective infiltration <strong>of</strong> neoplastic cells in the lumina <strong>of</strong> vessels<br />

and capillaries, with the exception <strong>of</strong> large arteries and veins<br />

[3]. The disease is widely disseminated in extranodal sites: the<br />

bone marrow, central nervous system, skin, lungs, liver, and<br />

spleen are the most common sites <strong>of</strong> involvement [4]. Lymph<br />

node infiltration and lymphadenopathy are usually absent<br />

[5]. The clinical signs and symptoms are variable, related<br />

to the site <strong>of</strong> involvement. Neoplastic cells are rarely seen in<br />

bone marrow and peripheral blood smears and so IVLBCL<br />

is very difficult to diagnose; most <strong>of</strong> the cases reported<br />

have been confirmed by autopsy or cutaneous biopsies [6].<br />

IVLBCL diagnosed in prostate specimens is extremely rare<br />

Figure 2. Neoplastic large cells filling the vessels are<br />

strongly positive with CD20 (immunoperoxidase, original<br />

magnification: x200).<br />

in the literature, usually reported as single cases; to the<br />

best <strong>of</strong> our knowledge, this is the 10th such case reported<br />

[1,7,8,9,10,11,12]. Furthermore, none <strong>of</strong> the patients in the<br />

study by Murase et al., with a large series <strong>of</strong> 96 patients, were<br />

diagnosed with prostatic involvement, indicating the rarity <strong>of</strong><br />

infiltration in this site [6].<br />

All reported cases <strong>of</strong> primary IVLBCL <strong>of</strong> the prostate are in<br />

elderly patients aged above 60 years [10], and the median age<br />

defined for all IVLBCL cases is 67 years (range: 13-85 years)<br />

[4].<br />

There are no specific laboratory findings indicating IVLBCL,<br />

but most patients were reported to display few pathologic<br />

findings in their complete blood counts, which should raise<br />

suspicion. Ferreri et al., in the study <strong>of</strong> a series <strong>of</strong> 38 patients,<br />

reported anemia in nearly 65% <strong>of</strong> patients, increased LDH and<br />

β2 microglobulin levels in more than 80% <strong>of</strong> patients, and an<br />

elevated sedimentation component in 14% <strong>of</strong> patients [1]. Our<br />

patient had an increased LDH level and mild thrombocytopenia.<br />

He had complaints indicating lower urinary tract symptoms,<br />

which led to a urinary tract examination. No increase in PSA<br />

levels was found, but ultrasonography revealed enlargement in<br />

prostatic dimensions, leading to p-TUR surgery. The diagnosis<br />

<strong>of</strong> IVLBCL was established based on histopathological and<br />

immunohistochemical assessment <strong>of</strong> the biopsy. Neoplastic<br />

cell infiltration was totally limited within the lumens <strong>of</strong> small<br />

vessels in the stroma, within benign acinar and glandular<br />

structures. Neoplastic cell infiltration was positive with CD20,<br />

MUM1, bcl-6, and bcl-2 and negative with ALK1, CD10,<br />

CD30, and cytokeratin, with a high Ki-67 proliferation index.<br />

CD34 and CD<strong>31</strong> staining with expression in endothelial cells<br />

highlighted the intravascular nature <strong>of</strong> the neoplastic infiltrate<br />

(Figures 1 and 2). The immunohistochemical pr<strong>of</strong>ile <strong>of</strong><br />

infiltration revealed a non-GCB cell phenotype (negative for<br />

CD10 and positive for IRF4/MUM1 and bcl-6) when classified<br />

according to the Hans criteria. Kanda et al. suggested that most<br />

IVLBCL cases might originate from post-germinal center cells,<br />

based on the presence <strong>of</strong> somatic mutation in variable regions<br />

<strong>of</strong> immunoglobulin heavy chain genes [13]. Subsequent<br />

studies supported their assertion as most IVLBCL cases have<br />

been reported to be <strong>of</strong> non-GCB cell origin [5,6].<br />

Our patient had no enlarged lymph nodes; bone marrow<br />

biopsy showed no infiltration <strong>of</strong> lymphoma. Upper abdominal<br />

ultrasonography revealed mild splenomegaly, but PET-CT<br />

showed no findings consistent with extra sites <strong>of</strong> infiltration;<br />

according to these findings, he had stage 1E disease. In a<br />

study <strong>of</strong> 38 intravascular lymphoma patients, Ferreri et al.<br />

reported that 40% <strong>of</strong> the patients diagnosed in vivo had stage<br />

1E disease according to the Ann Arbor staging system, but<br />

a disseminated infiltration was shown by autopsy in some<br />

stage I disease patients when death occurred a short time after<br />

diagnosis, highlighting the limitations <strong>of</strong> staging procedures<br />

Özsan N, et al: Intravascular Large B Cell Lymphoma<br />

in intravascular lymphoma patients [1,14]. The relatively high<br />

proportion <strong>of</strong> false negativity in classical staging procedures<br />

can be attributed to the fact that IVLBCL infiltration may<br />

usually be seen without tumor masses and apparent signs <strong>of</strong><br />

involvement or lymphadenopathy [15].<br />

The clinical manifestations <strong>of</strong> IVLBCL are extremely<br />

variable and symptoms are mostly related to the involved<br />

organ. Interestingly, clinical manifestations <strong>of</strong> the disease<br />

have been shown to differ between 2 distinct geographical<br />

areas. In Asian countries, hemophagocytic syndrome,<br />

bone marrow involvement, hepatosplenomegaly, fever, and<br />

thrombocytopenia have been documented at high frequencies,<br />

while central nervous system and skin involvements are<br />

predominantly seen in European countries [1,16]. Despite<br />

the defined geographical differences, neurological symptoms<br />

at initial diagnosis were reported in high incidences in both<br />

the Asian and Western types <strong>of</strong> the disease at 25% and 36%,<br />

respectively [1,17]. Among the few cases reported with<br />

prostatic involvement, 2 patients presented with neurological<br />

signs indicating spinal cord lesions [8,9]. Our patient had some<br />

neurological symptoms interpreted as myelitis according to MR<br />

findings, and following p-TUR surgery with spinal anesthesia,<br />

paraparesis developed. Whether these neurological symptoms<br />

were due to real neurological pathologies or to the invasion<br />

<strong>of</strong> tumor cells into the central nervous system or peripheral<br />

nerves remains unclear because an autopsy was not performed.<br />

The disease has an aggressive behavior, usually with a short<br />

outcome and fatal course [1]. The use <strong>of</strong> rituximab-containing<br />

chemotherapy regimens for the treatment <strong>of</strong> IVLBCL has been<br />

reported to improve outcomes [17,18].<br />

Ferreri et al. reported overall survival at 3 years as 81%<br />

in 33 patients receiving immunochemotherapy [18]. Highdose<br />

chemotherapy with the support <strong>of</strong> autologous stem cell<br />

transplantation was shown to have efficacy in several reports<br />

[19,20]. Despite all treatment modalities, our patient refused<br />

to receive treatment for lymphoma and unfortunately died <strong>of</strong><br />

the disease 8 months after the diagnosis.<br />

IVLBCL, though very rare, should be considered in<br />

differential diagnosis for elderly patients with elevated LDH<br />

levels, fever <strong>of</strong> unknown origin, and unexplained neurological<br />

symptoms. As for prostatic involvement, lower urinary tract<br />

obstruction symptoms can be seen, but an elevated level <strong>of</strong><br />

PSA is not a common finding for lymphoma infiltration<br />

in the prostate, including rare IVLBCL cases [21]. Biopsy<br />

and immunohistochemical assessment are required for the<br />

diagnosis. Early diagnosis can result in a better outcome with<br />

the recent treatment options. Further improvements in the<br />

understanding <strong>of</strong> the pathogenesis and biology <strong>of</strong> this rare<br />

type <strong>of</strong> lymphoma are mandatory to achieve better outcomes<br />

for IVLBCL patients.<br />

Introduction<br />

Bone marrow is one <strong>of</strong> the common sites to be involved<br />

with solid tumors that metastasize via the bloodstream.<br />

Micrometastases can be demonstrated in the bone marrow<br />

<strong>of</strong> 30%-75% <strong>of</strong> patients with common malignancies [1].<br />

Metastases involved in cortical bones <strong>of</strong>ten present with bony<br />

pain, pathologic fracture, and hypercalcemia [2]. Marrow<br />

involvement appears to be a prerequisite for the development,<br />

as bony metastases occur at the sites with hematopoietic<br />

marrow [2]. Extensive infiltration <strong>of</strong> the bone marrow<br />

may compromise hematopoietic functions. Hematologic<br />

abnormalities suggestive <strong>of</strong> marrow infiltration are peripheral<br />

cytopenia and leukoerythroblastic changes, and their<br />

occurrence is largely due to marrow replacement by tumor<br />

infiltration and reactive marrow fibrosis [2].<br />

Bone marrow aspirate and biopsy can be used to easily<br />

diagnose medullary metastases. The incidence <strong>of</strong> bone marrow<br />

involvement varies with types <strong>of</strong> primary tumors. The solid<br />

tumors most frequently detected in bone marrow in adults are<br />

carcinomas <strong>of</strong> the breast, prostate, lungs, and gastrointestinal<br />

tract [3,4]. Angiosarcomas are rare, comprising only about<br />

2% <strong>of</strong> all s<strong>of</strong>t tissue sarcomas. Primary angiosarcomas can<br />

occur at any site <strong>of</strong> the body. The most common sites are<br />

the skin and superficial s<strong>of</strong>t tissues, followed by the breast,<br />

liver, spleen, and bone. Primary splenic angiosarcoma is an<br />

uncommon primary tumor. Bone marrow metastasis in splenic<br />

angiosarcoma, however, is exceedingly rare.<br />

We report here the pathologic findings <strong>of</strong> a patient with<br />

bone marrow metastasis <strong>of</strong> a primary unsuspected splenic<br />

angiosarcoma.<br />

Case Presentation<br />

In December 2010, a 25-year-old woman complained <strong>of</strong><br />

anemic syndrome. She presented with serious normocytic<br />

normochromic anemia with nodular splenomegaly. Bone<br />

marrow biopsy was performed. Histopathological analysis<br />

found regular bone trabeculae and delimiting medullary<br />

compartments with normal cellular richness, where the 3<br />

myeloid lineages were represented at different maturation<br />

stages. There was a spindle proliferation delineating vascularlike<br />

slits, which were sometimes empty or contained<br />

erythrocytes. The cells presented moderate nuclear atypia,<br />

<strong>of</strong>ten with a prominent acidophilic nucleolus.<br />

The immunohistochemical study showed that spindle cells<br />

expressed CD34 and did not express CD<strong>31</strong>. Results for CD117<br />

(c-kit) were difficult to interpret (Figures 1 and 2).<br />

The medullary location <strong>of</strong> a vascular-like spindle<br />

proliferation was the most evident clue for diagnosis. Another<br />

bone marrow biopsy was recommended to better pinpoint the<br />

diagnosis. Informed consent was obtained.<br />

In January 2011, a second bone marrow biopsy was<br />

performed. Microscopic study highlighted, in the medullary<br />

compartments, a spindle proliferation with marked vascular<br />

differentiation. This was represented by slits or sometimes<br />

large virtual vascular cavities, surrounded and partitioned by<br />

turgescent endothelial cells. Islets <strong>of</strong> residual hematopoiesis<br />

were identified; they consisted <strong>of</strong> elements belonging to the 3<br />

myeloid lineages.<br />

The new immunohistochemical study showed the same<br />

pr<strong>of</strong>ile. The spindle cells did not express c-kit (CD117), with<br />

a positive internal control.<br />

The diagnosis <strong>of</strong> medullary location <strong>of</strong> vascular kaposiform<br />

proliferation was confirmed. Further immunostaining with<br />

HHV8 was performed and was negative (Figure 3). HIV<br />

serology and splenectomy were discussed.<br />

spindle cells proliferation, some cytologic atypia, and mitotic<br />

activity.<br />

Anoun S, et al: Primary Splenic Angiosarcoma<br />

angiosarcomas arising in the spleen have a unique propensity<br />

for bone marrow metastasis, but this is unfortunately not well<br />

documented in the literature [8]. We have found 3 cases in<br />

the literature in which primary splenic angiosarcoma was<br />

extended to the bone marrow.<br />

The KI-67 proliferation index determines prognosis.<br />

Because splenic angiosarcoma is a rare tumor, no specific<br />

regimen <strong>of</strong> chemotherapy has been employed in enough cases<br />

to enable the drawing <strong>of</strong> a conclusion as to effects on survival<br />

[6].<br />

Despite best efforts, the prognosis for this diagnosis is poor,<br />

with mean survival ranging from 10.3 to 14.4 months [9].<br />

Conclusion<br />

Figure 3. Microscopy: spindle proliferation with marked<br />

vascular differentiation. Nuclear atypia, with very few atypical<br />

cells and some calcifications.<br />

An abdominal computed tomography scan showed an<br />

enlarged spleen with heterogeneous lesions. Splenectomy<br />

was done in February 2011. The spleen weighed 706 g and<br />

measured 21x14x8 cm. The outer surface was smooth. When<br />

cut, multiple whitish nodules measuring between 0.4 and 1<br />

cm in diameter were seen. The splenic parenchyma was the<br />

site <strong>of</strong> saffron-colored deposits. At the hilum, 15 lymph nodes<br />

were isolated, measuring between 4 and 12 mm in diameter.<br />

Histological examination showed that the nodules described<br />

above corresponded to a spindle proliferation with marked<br />

vascular differentiation. Cells were sometimes epithelioidlike,<br />

presenting moderate to marked nuclear atypia, with<br />

very few atypical cells and budding nuclei, estimated at 10<br />

mitoses per 10 fields at high magnification. Vascular slits were<br />

engorged by erythrocytes<br />

Moreover, there were calcifications with giant cells and a<br />

small focus <strong>of</strong> necrosis.<br />

Fourteen lymph nodes among the 15 examined were<br />

metastatic.<br />

The final diagnosis was that <strong>of</strong> a well-differentiated<br />

angiosarcoma (grade II) <strong>of</strong> the spleen with lymph node<br />

metastases (14 N+ <strong>of</strong> 15).<br />

The patient received a chemotherapy course. Unfortunately,<br />

the patient died 1 year after the splenectomy from metastasis.<br />

Discussion and Review <strong>of</strong> the Literature<br />

Primary splenic angiosarcoma is the most common<br />

malignant non-hematopoietic tumor <strong>of</strong> the spleen [5]. These<br />

tumors are rare, highly aggressive, and lethal. Metastases tend<br />

to occur early and spread widely [6]. Metastatic diseases were<br />

found in 69% <strong>of</strong> the patients in a reported series [7]. Early<br />

metastasis from splenic angiosarcoma largely contributes to its<br />

poor prognosis. Up to 86% <strong>of</strong> patients have distant metastases<br />

at the time <strong>of</strong> presentation. Bone marrow metastasis, however,<br />

is exceptionally rare. Interestingly, Wang et al. suggested that<br />

We believe that the true incidence <strong>of</strong> bone marrow<br />

metastasis is underreported. Bone marrow aspiration and<br />

biopsy should be systematically performed in angiosarcoma<br />

patients, especially when hematological abnormalities are<br />

found on blood count.<br />

Introduction<br />

Onychomycosis is a very frequent fungal nail infection.<br />

The prevalence can be as high as 28%-40%, especially in<br />

elderly populations. Terbinafine is an antifungal agent<br />

with both fungicidal and fungistatic properties, which is<br />

highly effective and is the most frequently used agent in<br />

onychomycosis. Oral terbinafine is generally well tolerated<br />

with minimal reports <strong>of</strong> serious drug reactions. These rare<br />

adverse events are mostly reported as case presentations, and<br />

it is important to be familiar with them in order to be able<br />

to evaluate the risk and inform patients accordingly [1,2,3].<br />

Here we report a case <strong>of</strong> aplastic anemia (AA) associated<br />

with oral terbinafine use and a review <strong>of</strong> the literature<br />

on hematological toxicities associated with terbinafine.<br />

Written informed consent was obtained from the patient<br />

and her husband for publication <strong>of</strong> this manuscript and<br />

Kantarcıoğlu B, et al: Aplastic Anemia and Terbinafine<br />

Case Presentation<br />

A 41-year-old female presented with malaise, severe<br />

fatigue, nausea, and vaginal bleeding in April 2011. In her<br />

past history she was healthy, except that she reported taking<br />

terbinafine pills for 8 weeks for the treatment <strong>of</strong> longstanding<br />

recurrent toenail onychomycosis. She did not report any<br />

immune reactions or allergies to any drugs or substances. Her<br />

previous gynecological examination was normal, with a normal<br />

β-human chorionic gonadotropin level. Her complete blood<br />

count (CBC) revealed pancytopenia with white blood cell<br />

count <strong>of</strong> 3.2x109/L, absolute neutrophil count <strong>of</strong> 0.8x10 9 /L,<br />

hemoglobin <strong>of</strong> 7.4 g/dL, and platelet count <strong>of</strong> 34x10 9 /L. Her<br />

physical examination was unremarkable with no evidence <strong>of</strong><br />

lymphadenopathy or organomegaly, except for a few petechiae<br />

and ecchymoses on bilateral legs. Peripheral blood smear was<br />

consistent with pancytopenia. Reticulocyte count was 0.7.<br />

Liver enzymes were elevated [AST: 61 U/L (N: 10-37 U/L),<br />

ALT: 117 U/L (N: 10-40 U/L), ALP: 434 U/L (N: 0-270 U/L),<br />

GGT: 471 U/L (N: 7-49 U/L)]. Renal function tests and lactate<br />

dehydrogenase were normal. Bone marrow aspiration and<br />

biopsy revealed severe reduction <strong>of</strong> all cell lineages without<br />

evidence <strong>of</strong> neoplastic infiltration, dysplasia, or fibrosis.<br />

The counted cellularity was 5% in bone marrow. Bone<br />

marrow karyotype analysis was normal. A gastroenterology<br />

consultation performed for the liver enzyme abnormalities did<br />

not provide an etiologic factor, pointing toward drug-induced<br />

hepatitis. Further work-ups, including levels <strong>of</strong> vitamin B12<br />

and folate; neck, chest, and abdominopelvic computerized<br />

tomography; serology and polymerase chain reaction (PCR)<br />

tests for viral hepatitis, human immunodeficiency, Epstein-Barr<br />

virus, parvovirus B19, and cytomegalovirus; FLAER test for<br />

paroxysmal nocturnal hemoglobinuria; antinuclear antibody<br />

test; HLA-DRB1*15; and quantiferon test for tuberculosis,<br />

were all negative. The patient was diagnosed with AA,<br />

which was not severe at that time. Terbinafine treatment was<br />

stopped. Due to the use <strong>of</strong> a drug with probable hematologic<br />

toxicity, follow-up with supportive care was planned for the<br />

patient. During 3-4 weeks <strong>of</strong> follow-up time, blood values<br />

worsened with the need for erythrocyte and thrombocyte<br />

transfusions, in accordance with very severe AA (SAA). She<br />

did not have a matched related donor for transplantation.<br />

After confirming the diagnosis with a second bone marrow<br />

biopsy, she received rabbit antithymocyte globulin (ATG) plus<br />

cyclosporine-A (CYC). The clinical outcome after ATG + CYC<br />

was poor due to transient worsening <strong>of</strong> hematopoiesis and<br />

infectious complications. She spent 3 months in the hospital<br />

with perianal abscess, invasive aspergillosis, zoster virus<br />

reactivation, and several catheter infections. She required<br />

physical and psychological rehabilitation. Fortunately, the<br />

blood values began to recover at the end <strong>of</strong> the fourth month<br />

and full hematologic recovery was achieved at the end <strong>of</strong> the<br />

sixth month. The patient is still in complete remission after 18<br />

months <strong>of</strong> ATG + CYC treatment (Figures 1 and 2).<br />

Discussion and Review <strong>of</strong> the Literature<br />

Onychomycosis refers to all fungal infections <strong>of</strong> the nails.<br />

It is difficult to cure, has high recurrence rates, and can<br />

significantly affect a patient’s quality <strong>of</strong> life. Topical therapies<br />

are generally ineffective, and today treatment with systemic<br />

antifungal agents is accepted as the gold standard method for<br />

onychomycosis. In clinical trials, continuous terbinafine has<br />

repeatedly demonstrated higher efficacy when compared to<br />

other antifungal treatments. The recommended dosage for the<br />

treatment <strong>of</strong> onychomycosis is 250 mg/day orally for 12 weeks<br />

for toenails and 6 weeks for fingernails [1,2,3].<br />

Oral terbinafine is generally well tolerated with minimal<br />

reports <strong>of</strong> serious drug reactions. Two large-scale postmarketing<br />

surveillance studies showed that the incidence <strong>of</strong> serious<br />

To the Editor,<br />

The thymus can be detected by ultrasonography until<br />

the pre-adolescent period. After the early teens, it begins to<br />

decrease in size [1]. In thalassemia patients, all organs have the<br />

risk <strong>of</strong> organ dysfunction because <strong>of</strong> iron overload. Only a few<br />

studies showed the size <strong>of</strong> the thymus in older children and<br />

there were no studies in thalassemia patients [2,3]. The side<br />

effects <strong>of</strong> iron overload in thalassemia major (TM) patients’<br />

organs were examined through a literature search, but it<br />

appears that the thymus has not been emphasized enough to<br />

provide an adequate number <strong>of</strong> studies. The purpose <strong>of</strong> this<br />

study was to determine whether the size <strong>of</strong> the thymus in<br />

thalassemia patients differed from that in healthy children.<br />

Sixty-five children with TM, aged 1 to 19 years, who had<br />

been followed up in the pediatric hematology department at<br />

Harran University were enrolled in the study between 1 July<br />

and <strong>31</strong> July 2012. Fort-three TM patients and healthy siblings<br />

<strong>of</strong> patients with another diagnosis were enrolled as a control<br />

group because there was no literature related to the normal<br />

range <strong>of</strong> thymus size for children older than 8 years.<br />

The thymic size (thymic index) was calculated by multiplying<br />

the largest transverse diameter by the largest longitudinal<br />

diameter, measured in millimeters by ultrasonography (Toshiba<br />

Corporation Medical System Division, Tokyo, Japan, type SSA<br />

240 A with a 7.5-MHz linear probe) [4]. Ultrasonography was<br />

Figure 1. Dot plot <strong>of</strong> thymic index among children with TM<br />

(□—.) and healthy controls (○ ----) at various ages.<br />

performed by the same radiologist. The average ferritin levels<br />

for the last 6 months were recorded.<br />

The study was approved by the Ethics Committee <strong>of</strong><br />

Harran University. The differences between groups were tested<br />

with Mann-Whitney U tests. Correlations were evaluated with<br />

Spearman’s test.<br />

Oymak Y, et al: Thymic Index and Thalassemia<br />

The characteristics <strong>of</strong> the TM patients and the control<br />

group are shown in Table 1. There were no differences in terms<br />

<strong>of</strong> sex, age, weight, and height. However, the thymic index<br />

<strong>of</strong> the TM patients was lower than that <strong>of</strong> the control group<br />

(Figure 1).<br />

The TM patients’ mean (± standard deviation) ferritin level<br />

was 2967 (±1842) µg/mL. Ferritin level and thymic index did<br />

not correlate (r=-0205, p=0.104). Seven (10.7%) TM patients<br />

were splenectomized. The median (min-max) thymic index <strong>of</strong><br />

the splenectomized patients was 0.0 (0.0-304.0); it was 230.5<br />

(0.0-903.0) in the non-splenectomized patients (p=0.001).<br />

Splenectomized patients were older than non-splenectomized<br />

patients (p=0.001).<br />

In TM patients, the thymic index has not been previously<br />

studied. Although corticosteroid effect was eliminated and<br />

there were no differences in the age, sex, weight, and height,<br />

the thymic index <strong>of</strong> the TM patients was lower than that <strong>of</strong> the<br />

control group. Iron overload is the best-known harmful effect<br />

<strong>of</strong> chronic transfusion on organs, and it might affect the thymus<br />

as well. The size <strong>of</strong> the thymus is affected by several factors<br />

like steroids, infections, and X-rays [5,6,7,8,9]. It has also been<br />

found that thymus activity is related to thymus size [10]. In this<br />

study, finding a difference in thymus size between TM patients<br />

and controls supported the hypothesis that chronic transfusions<br />

might affect the thymus; however, there were weaknesses in<br />

the groups’ histories in terms <strong>of</strong> infection, malnutrition, and<br />

having undergone X-rays. This is a preliminary study, and the<br />

only difference that we knew about was that the groups were<br />

receiving chronic blood transfusions, which might contribute<br />

to decreased thymus size in TM patients. Zinc level, which is<br />

known to be lower in TM patients, may affect the size <strong>of</strong> the<br />

thymus, but there were no data available about the zinc levels<br />

<strong>of</strong> our patients [8]. This study found no association between<br />

the thymic index and ferritin level; however, each organ may<br />

be affected to a different degree by the same ferritin level [11].<br />

Smaller thymus sizes in splenectomized patients might depend<br />

on their older ages.<br />

control group.<br />

It was also shown that stress and aging caused thymic<br />

involution, which might protect the organism from the danger<br />

<strong>of</strong> autoimmune diseases [12]. In one study it was shown that<br />

thymus size declined with age in both children with atopic<br />

dermatitis and healthy controls. However, the size <strong>of</strong> the<br />

thymus among children with active atopic dermatitis was<br />

higher compared to healthy controls [3]. Having a smaller<br />

thymus may be an advantage for TM patients, who are prone to<br />

alloimmunization related to transfusion.<br />

In conclusion, thymic involution occurred more rapidly<br />

in the TM group than in the normal controls. Further studies<br />

that include other parameters, such as T2 magnetic resonance<br />

imaging <strong>of</strong> the thymus for iron load and factors that may affect<br />

thymus size, with bigger sample sizes are required to objectively<br />

determine the effect <strong>of</strong> iron overload on thymic involution.<br />

Hyperimmunoglobulin M syndrome (HIGM) is a<br />

primary immunodeficiency characterized with low IgG,<br />

IgA, and IgE and normal or elevated IgM levels due to<br />

a defect in class switching recombination [1]. In this<br />

report, we present a patient with CD40 ligand (CD40L)<br />

deficiency who had arthritis and hypertransaminasemia<br />

with no history <strong>of</strong> serious infection until 8 years <strong>of</strong> age.<br />

An 8-year-old male patient presented because <strong>of</strong> a<br />

2-year history <strong>of</strong> knee swelling and pain. The patient had<br />

no history <strong>of</strong> serious infection and he had been followed<br />

for asthma and elevated transaminase level by the<br />

Department <strong>of</strong> Pediatric Gastroenterology for the past 3<br />

years. His parents were not relatives. Physical examination<br />

revealed the following: both knees had tenderness,<br />

swelling, redness, and limited range <strong>of</strong> motion. Other<br />

systems were normal. Laboratory analysis revealed the Figure 1. a) There is c.761C>T mutation in the CD40 ligand gene. b)<br />

following results: Hb: 11.7 g/dL, Hct: 37.7%, MCV: 71.7 MR cholangiography findings: dilated common choledochal (black<br />

fL, leukocytes: 8.0x109/L, platelets:405x10 9 /L, CRP: 18 star) and intrahepatic bile ducts, narrowing <strong>of</strong> the bile ducts, and<br />

irregularities at multiple levels (white arrows). c) Bile duct with<br />

results and no pathogen could be isolated. Flow cytometry<br />

revealed CD40L deficiency, while analysis showed c.761C>T<br />

mutation in the same gene (Figure 1a). The patient was<br />

diagnosed with HIGM syndrome. A liver biopsy was done and<br />

magnetic resonance (MR) cholangiography was conducted<br />

for hypertransaminasemia. MR cholangiography and biopsy<br />

specimen findings were consistent with sclerosing cholangitis<br />

(Figures 1b and 1c). Informed consent was obtained.<br />

In HIGM syndrome, clinical findings occur at early<br />

ages and the mean age <strong>of</strong> diagnosis is less than 1 year.<br />

Clinically, HIGM has similarities with recurring respiratory<br />

tract infections causing bronchiectasis and other humoral<br />

immune deficiencies presenting with sinus and ear infections<br />

[2]. Recurrent respiratory infections were absent in our<br />

case. Additionally, our patient was diagnosed with asthma.<br />

Recurrent respiratory infections may be confused with asthma<br />

attacks by physicians. Therefore, our patient could have been<br />

diagnosed late.<br />

Although other markers were negative, anti-CMV IgM<br />

values were always high in this case. CMV-DNA PCR tests,<br />

applied at intervals, were also negative. In HIGM syndrome,<br />

the serum IgM level is normal or high but serum IgG and IgA<br />

levels are low, because <strong>of</strong> a defect in isotype class switching<br />

<strong>of</strong> B cells [3]. Furthermore, there is no response to protein<br />

antigens, though some IgM anti-polysaccharide antibodies,<br />

including isohemagglutinins, can be produced [2]. Therefore,<br />

our patient had CMV IgM probably due to CMV infection.<br />

However, he could not produce CMV IgG because <strong>of</strong> the<br />

nature <strong>of</strong> his disease.<br />

Our patient was being monitored due to<br />

hypertransaminasemia in the gastroenterology outpatient<br />

clinic. Abdominal ultrasonography showed no cholangiopathy,<br />

but MR cholangiography findings were consistent with<br />

sclerosing cholangitis. Portal fibrosis was seen in only 1 <strong>of</strong> 4<br />

vena portae samples in his liver biopsy. The most common<br />

characteristic finding <strong>of</strong> liver biopsy for sclerosing cholangitis<br />

is interlobular and septal fibrosis <strong>of</strong> bile ducts known as ‘onion<br />

skin’ [4]. Our findings <strong>of</strong> liver biopsy were not characteristic<br />

for sclerosing cholangitis. When clinical and radiological<br />

findings were evaluated together with liver biopsy results, the<br />

patient was diagnosed with sclerosing cholangitis in an initial<br />

state.<br />

In conclusion, idiopathic arthritis and persistent<br />

hypertransaminasemia should also be considered in the<br />

differential diagnosis <strong>of</strong> primary immune deficiencies.<br />

A 78-year-old Caucasian female patient presented<br />

to our department with a cutaneous lesion on her right<br />

shoulder (Figure 1a). Laboratory data disclosed mild anemia<br />

(hemoglobin: 11.3 g/dL) thrombocytopenia (139x10 9 /L) and<br />

30% morphologically immature atypical cells in the peripheral<br />

blood. Bone marrow aspiration showed 5% infiltration <strong>of</strong><br />

immature blast cells with the following immunophenotype:<br />

CD45 (+), CD123 (+), CD85k (+), CD33 (-), CD14 (-), CD16<br />

(-), CD19 (-), CD5 (-), CD10 (-), CD20 (-), CD56 (+) 20%,<br />

CD4 (+), NG2 (+). No chromosomal alterations were detected<br />

by cytogenetic analysis <strong>of</strong> the bone marrow (46,XX). Specific<br />

karyotypic aberrations were not found. She had axillary, jugular,<br />

submandibular, and supraclavicular lymphadenopathy.<br />

Cutaneous, lymph node, and bone marrow biopsy confirmed<br />

the diagnosis <strong>of</strong> blastic plasmacytoid dendritic cell neoplasm<br />

(BPDCN). She was treated with cyclophosphamide,<br />

vincristine, adriamycin, and dexamethasone (Cy-VAD) as part<br />

<strong>of</strong> an acute lymphoblastic leukemia treatment-protocol. She<br />

achieved first complete remission. Due to the highly aggressive<br />

type <strong>of</strong> leukemia, we decided to continue with induction 2<br />

chemotherapy (etoposide-cytosine arabinoside), but she died<br />

5 months after the first sign due to multiorgan failure.<br />

One year later, a 75-year-old Caucasian male patient<br />

presented with a generalized purplish skin rash from the<br />

head to the lower extremities that expanded very rapidly<br />

(Figure 1b and 1c). Laboratory data revealed anemia<br />

(hemoglobin: 10.9 g/dL), thrombocytopenia (100x109/L), and<br />

42% morphologically immature atypical cells in the peripheral<br />

blood. Bone marrow aspiration showed 88% infiltration <strong>of</strong><br />

immature blast cells with the following immunophenotype:<br />

CD45 (+) low, CD43 (+), CD123 (+), CD56 (+), CD4 (+),<br />

CD34 (-). Computed tomography scans did not disclose<br />

pathologic lymphadenopathy. Histopathology <strong>of</strong> skin lesions<br />

showed blast cell infiltrate. Immunohistochemical analysis<br />

confirmed the presence <strong>of</strong> cells with the aforementioned<br />

immunophenotypic features. A basic immunophenotype with<br />

CD4 (+), CD56 (+), CD123 (+), and negative T, B, and NK<br />

cells led to the diagnosis <strong>of</strong> BPDCN as per the current WHO<br />

classification [1]. In the cytogenetic analysis, a pathologic<br />

karyotype was found (46,XY, del (12), (p12), del (17), (p11)<br />

[17]/46,XY [13]). He began acute myeloid leukemia-type<br />

chemotherapy with idarubicin and arabinoside-c and he<br />

achieved complete remission after induction. We changed<br />

his treatment plans and continued with CHOP due to his<br />

poor performance status, and, after 4 cycles, he still remains<br />

without clinical signs. Informed consent was obtained.<br />

Plasmacytoid dendritic cells were first identified 50<br />

years ago by Lennert and his associates [2]. BPDCN is a<br />

rare, highly aggressive hematopoietic malignancy that is<br />

characterized by cutaneous infiltration with or without<br />

bone marrow involvement. Its overall incidence is extremely<br />

low. The leukemic form <strong>of</strong> the disease is very rare. BPDCN<br />

predominantly affects males, and generally the elderly [3].<br />

The majority <strong>of</strong> patients present with asymptomatic solitary<br />

or multiple cutaneous reddish-brown nodules. Clinically, this<br />

malignancy generally presents in the skin, <strong>of</strong>ten followed by<br />

bone marrow and blood involvement. However, any organ can<br />

be affected. The disease follows a short course and fulminant<br />

leukemia is the common terminal stage. Diagnosis is based<br />

on the expression <strong>of</strong> CD4, CD56, and CD123 in the absence<br />

<strong>of</strong> T-cell, B-cell, or myeloid markers. Although identification<br />

<strong>of</strong> the immunophenotypic features <strong>of</strong> BPDCN has improved<br />

its recognition, this entity remains diagnostically challenging.<br />

Insufficient knowledge <strong>of</strong> this entity and inadequate<br />

immunophenotypic investigation can lead to the misdiagnosis<br />

<strong>of</strong> a different leukemia. The prognosis <strong>of</strong> patients with BPDCN<br />

is poor, with a median survival <strong>of</strong> 12 months regardless <strong>of</strong><br />

treatment type. Acute lymphoblastic leukemia-type treatment<br />

regimens are advised and a promising initial response may<br />

occur, but this is followed by quick relapse [4]. There is also<br />

the option <strong>of</strong> bone marrow transplantation for young patients<br />

with an acceptable performance status.<br />

In conclusion, we encountered a rare type <strong>of</strong> leukemia. The<br />

rarity <strong>of</strong> this disease does not enable prospective clinical trials<br />

to identify a better therapeutic strategy, which, at present, is<br />

based on clinicians’ experience and on cooperation among<br />

them.<br />

To the Editor,<br />

Here we describe, for the first time, a hemodialysis patient<br />

suffering from adult T-cell leukemia/lymphoma (ATL) who<br />

was treated with mogamulizumab, a defucosylated anti-CC<br />

chemokine receptor 4 (CCR4) monoclonal antibody [1].<br />

An 83-year-old female was admitted to the hospital suffering<br />

from fatigue, leukocytosis, and hypercalcemia. On admission,<br />

laboratory tests revealed that her leukocyte count was elevated<br />

to 76x109/L (>80% abnormal lymphocytes). Blood chemistry<br />

analysis revealed elevated lactate dehydrogenase (LDH: 808<br />

IU/L) and soluble interleukin-2 receptor (sIL-2R: 43.465 U/<br />

mL). Seropositivity for human T-cell leukemia virus type-1<br />

(HTLV-1) was confirmed and monoclonal integration <strong>of</strong> HTLV-<br />

1 was detected by Southern blotting <strong>of</strong> DNA isolated from<br />

peripheral blood (PB). She was diagnosed with acute ATL.<br />

Flow cytometric analysis demonstrated that the abnormal<br />

lymphocytes were CD3+CD4+CD25+. Computed tomography<br />

(CT) revealed multiple lymphadenopathies, involving the<br />

supraclavicular fossae and the inguinal, mediastinum, and<br />

para-aortic regions.<br />

She was treated with systemic chemotherapy (THP-<br />

COP regimen: cyclophosphamide, pirarubicin, vincristine,<br />

and prednisolone) on day 8 post-admission. Although the<br />

number <strong>of</strong> ATL cells in the PB gradually decreased, they<br />

were persistent. On day 18 <strong>of</strong> THP-COP, she experienced<br />

a high fever and hypotension. Because serum β-D-glucan<br />

levels were elevated and a chest CT revealed a pulmonary<br />

infiltrate, she was administered cefepime and voriconazole.<br />

However, she developed anuric acute renal failure, probably<br />

induced by voriconazole, and so emergent hemodialysis<br />

was initiated. Subsequently, both the number <strong>of</strong> ATL cells<br />

(cyclophosphamide, pirarubicin, vincristine, and prednisolone)<br />

and mogamulizumab administration. WBC counts, ATL cell<br />

counts, and LDH and creatinine levels throughout the clinical<br />

course, and the concentration <strong>of</strong> mogamulizumab in the<br />

plasma pre- and post-dialysis, are shown. CHDF: Continuous<br />

hemodiafiltration, HD: hemodialysis.<br />

and her LDH levels increased, suggesting that the THP-COP<br />

regimen was not working. Because the ATL cells expressed<br />

high levels <strong>of</strong> CCR4, she received an intravenous infusion <strong>of</strong><br />

mogamulizumab (1.0 mg/kg) once a week for 8 weeks. The<br />

concentration <strong>of</strong> mogamulizumab in the plasma was measured<br />

using an enzyme-linked immunosorbent assay [2,3]. The<br />

plasma concentrations <strong>of</strong> mogamulizumab before and after<br />

hemodialysis during the first mogamulizumab infusion and<br />

just before the second infusion (Ctrough) were 14,104.8 ng/mL,<br />

16,092.2 ng/mL, and 5901.2 ng/mL, respectively. The plasma<br />

levels <strong>of</strong> mogamulizumab before and after hemodialysis were<br />

comparable, and Ctrough was in the range <strong>of</strong> published data<br />

[2], suggesting that therapeutic levels <strong>of</strong> mogamulizumab may<br />

be maintained in patients undergoing dialysis (Figure 1). Five<br />

months after the mogamulizumab treatment the leukemia<br />

relapsed. However, the patient did not accept any further<br />

treatment or a rechallenge with mogamulizumab. She was<br />

managed with best supportive care, and she died 10 months<br />

after diagnosis with ATL.<br />

ATL is an aggressive peripheral T-cell neoplasm that<br />

cannot usually be cured by conventional chemotherapy [4,5].<br />

Allogeneic hematopoietic stem cell transplantation is now<br />

considered the only curable treatment for young patients with<br />

ATL, but it is not applied to elderly patients because <strong>of</strong> higher<br />

toxicities. Currently, chemotherapy is the only therapeutic<br />

option for elderly ATL patients but there are concers about<br />

their safety and efficacy [6]. Mogamulizumab is a humanized<br />

anti-CCR4 antibody with a defucosylated Fc region and has<br />

been used to treat relapsed/refractory CCR4-positive ATL with<br />

50% efficacy in a phase II study [3,7]. The fucose content in the<br />

oligosaccharide structure in the Fc region <strong>of</strong> mogamulizumab<br />

is reduced using Potelligent technology, which enhances the<br />

antibody-dependent cellular toxicity because <strong>of</strong> increased<br />

binding affinity to the Fcγ receptor on effector cells [8]. More<br />

recently, mogamulizumab was also approved for the treatment<br />

<strong>of</strong> relapsed CCR4-positive peripheral T-cell lymphoma and<br />

cutaneous T-cell lymphoma in Japan [9].<br />

To date, limited data exist about the application <strong>of</strong><br />

mogamulizumab in patients undergoing hemodialysis. Here,<br />

mogamulizumab treatment resulted in complete remission<br />

<strong>of</strong> an elderly ATL patient with no major adverse events such<br />

as infusion reaction or skin rash (including re-exacerbation<br />

<strong>of</strong> renal function). Thus, administration <strong>of</strong> mogamulizumab<br />

may be considered as a safe therapeutic option in this setting.<br />

The present case shows that therapeutic mogamulizumab<br />

levels can be achieved and maintained in patients undergoing<br />

hemodialysis as mogamulizumab is not eliminated by the<br />

procedure.<br />

To the Editor,<br />

Chediak-Higashi syndrome (CHS) is a rare, autosomal<br />

recessive inherited disorder characterized by variable degrees<br />

<strong>of</strong> oculocutaneous albinism, severe immune deficiency<br />

and unassociated lymphoproliferative syndrome, and<br />

intracytoplasmic giant granules in leukocytes, monocytes,<br />

platelets, melanocytes, and erythroid precursors [1,2,3,4,5].<br />

CHS is caused by mutations in the lysosomal trafficking<br />

regulator gene (LYST) [3,6]. The role <strong>of</strong> the LYST gene in the<br />

trafficking <strong>of</strong> granules results in defective release <strong>of</strong> melanin<br />

or cytolytic enzymes, causing hypopigmentation <strong>of</strong> the skin<br />

and hair as well as cytotoxic defect [3]. There are 2 clinical<br />

periods <strong>of</strong> the disease: stable and accelerated. In the accelerated<br />

phase, fever, hepatosplenomegaly, hepatitis, lymphohistiocytic<br />

infiltration, pancytopenia, coagulopathy, hemorrhage, and<br />

peripheral neuropathy are seen [1]. Herein, we report a case<br />

<strong>of</strong> CHS presented with hemophagocytic lymphohistiocytosis<br />

(HLH).<br />

A 5-month-old girl presented with fever. She was febrile and<br />

pale, and she had splenomegaly with no hepatomegaly. There<br />

were no neurological symptoms, lymphadenopathy, or bleeding<br />

signs. Her body temperature was over 38.8 °C for 8 days in spite<br />

<strong>of</strong> ampicillin/sulbactam and netilmicin therapy. Hematological<br />

investigation revealed hemoglobin <strong>of</strong> 6.3 g/dL, white blood cell<br />

count <strong>of</strong> 3.8x109/L (70% lymphocytes, 10% neutrophils), and<br />

Figure 1. A. Hemophagocytosis on bone marrow smear.<br />

B. An intracytoplasmic giant granule in a monocyte on<br />

peripheral blood smear.<br />

C. Light microscopic image <strong>of</strong> the hair shaft shows abnormal<br />

clumping <strong>of</strong> melanin in patient’s hair. Pigment clumbs are<br />

small and uniformly and regularly distributed along the hair<br />

shaft. This is consistant with Chediak-Higashi syndrome.<br />

D. Our patient does not have oculocutaneous albinism and<br />

she is black-haired.<br />

analysis for CHS was consistent with CHS. At the end <strong>of</strong> the<br />

initial therapy, the disease was in remission. Continuation<br />

therapy <strong>of</strong> the HLH regimen was then started. Stem cell<br />

transplantation (SCT) has been planned. As there was no<br />

matched related donor for SCT at that time, we will be treating<br />

her according to HLH-2004 continuation therapy until a<br />

matched or mismatched unrelated donor is found. Informed<br />

consent was obtained.<br />

Our patient was diagnosed with HLH because there<br />

was hemophagocytosis on bone marrow aspiration (Figure<br />

1a) and she had splenomegaly, fever, pancytopenia,<br />

hypertriglyceridemia, and high ferritin levels. Sometimes the<br />

CHS diagnosis can be considered only after the observation<br />

<strong>of</strong> gray hair and giant intracellular granules on a peripheral<br />

blood smear, and light microscopy <strong>of</strong> a hair shaft can facilitate<br />

a quick diagnosis [2]. We thought that the diagnosis could be<br />

CHS because <strong>of</strong> the bone marrow aspiration and peripheral<br />

blood smears findings (Figure 1b). Light microscopic images<br />

<strong>of</strong> the patient’s hair showed abnormal clumping <strong>of</strong> melanin.<br />

Pigment clumps were small and uniformly and regularly<br />

distributed along the hair shaft (Figure 1c). Our patient was<br />

therefore diagnosed by hair analysis although she does not<br />

have the CHS phenotype (Figure 1d).<br />

Patients with CHS may have a variable clinical presentation<br />

due to different mutations in the LYST gene. Nonsense and<br />

frameshift mutations <strong>of</strong> the LYST gene are associated with<br />

severe early-onset childhood CHS and characterized by fatal<br />

infections and HLH. Meanwhile, missense mutations <strong>of</strong> the<br />

same gene are associated with milder, late-onset CHS with<br />

slowly progressive neurological impairment or an adolescent<br />

form with infections but no HLH [2,6,7]. In our case there is<br />

probably a mutation <strong>of</strong> the LYST gene that is associated with<br />

the normal phenotype and the specific findings <strong>of</strong> CHS on<br />

peripheral blood smear, bone marrow aspiration smear, and<br />

light microscopic image <strong>of</strong> the hair shaft but causes earlyonset<br />

HLH. Genetic analysis is needed to explain this exactly.<br />

In our case there was no specific treatment for CHS.<br />

Intravenous antibiotherapy, erythrocyte suspension,<br />

thrombocyte suspension, and, in accordance with the HLH<br />

2004 protocol, dexamethasone and etoposide were used. The<br />

patient has been positively responsive to chemotherapy and,<br />

as the main treatment <strong>of</strong> CHS, SCT is planned, but a donor has<br />

not yet been found [8].<br />

In conclusion, we think that it is not necessary to find<br />

oculocutaneous albinism and silvery hair in all patients to<br />

diagnose CHS. Bone marrow aspiration and peripheral blood<br />

smears and light microscopic images <strong>of</strong> the hair shaft may be<br />

sufficient for diagnosis in some cases without genetic analysis.<br />

To the Editor,<br />

Bone marrow cells with morphological characteristics<br />

similar to Gaucher cells and without cytoplasmic crystalline<br />

inclusions are rare. These Gaucher-like or pseudo-Gaucher<br />

cells can be seen in a variety <strong>of</strong> conditions such as acute<br />

lymphoblastic leukemia, multiple myeloma, myelodysplasia,<br />

Hodgkin’s disease, thalassemia, and disseminated<br />

mycobacterial infection [1,2,3,4,5,6,7,8]. Since the presence <strong>of</strong><br />

these cells may obscure neoplastic cells in multiple myeloma<br />

and may lead to misdiagnosis, it is important for hematologists<br />

and hematopathologists to be aware <strong>of</strong> such a condition in<br />

order to make a prompt and accurate diagnosis. Herein we<br />

report a case <strong>of</strong> multiple myeloma in which the presence <strong>of</strong><br />

plasma cells was missed on initial histological diagnosis.<br />

A 44-year-old female without history <strong>of</strong> any previous<br />

systemic disease presented with oliguria, easy fatigability, and<br />

breathlessness for 7 days. On examination she had crepitating<br />

rales, jugular venous congestion, abdominal distension, and<br />

pretibial edema. The complete blood count showed Hb <strong>of</strong> 67<br />

g/L, WBC count <strong>of</strong> 3.4x109/L, and platelet count <strong>of</strong> 69x10 9 /L.<br />

Erythrocyte sedimentation rate was 112 mm/h. Bone marrow<br />

aspirate and biopsy were performed. The bone marrow aspirate<br />

revealed numerous large cells with plentiful cytoplasm and a<br />

small eccentric nucleus. Scattered among these were plasma<br />

cells, which were obscured by sheets <strong>of</strong> Gaucher-like cells<br />

(Figure 1A). Immunohistochemical staining <strong>of</strong> bone marrow<br />

biopsy showed that plasma cells were positive for CD38 and<br />

kappa light chain (Figures 1B and 1C), and the large cells<br />

were positive for CD68 (Figure 1D). There were crystalline<br />

Figure 1. (A) Bone marrow aspirate smear (Giemsa 400x)<br />

showing pseudo-Gaucher cells with abundant cytoplasm,<br />

dense round deposits, and an eccentric pyknotic nucleus;<br />

immunohistochemical staining <strong>of</strong> bone marrow biopsy<br />

showed that plasma cells were positive for (B) CD38 and (C)<br />

kappa light chain; (D) the large cells were positive for CD68.<br />

inclusion bodies within these cells, which were negative for<br />

smooth muscle actin, HHF-35, and keratin. The erythroid and<br />

myeloid series were normal. Serum electrophoresis revealed<br />

an M band. Skull X-ray showed lytic bone lesions. Taken<br />

together, a diagnosis <strong>of</strong> multiple myeloma associated with a<br />

prominent pseudo-Gaucher histiocytic response was made.<br />

Gaucher-like cells have been described in various<br />

hematological disorders [1,2,3,4,5,6,7,8]. These cells are<br />

considered to be marrow macrophages seen in circumstances<br />

related to high cell turnover [9]. One striking feature is that<br />

pseudo-Gaucher cells cannot be distinguished from true<br />

Gaucher cells by routine hematoxylin-eosin staining. In order<br />

to differentiate them, iron staining should be performed.<br />

Gaucher cells show diffuse iron staining whereas pseudo-<br />

Gaucher cells do not. Electron microscopical features may also<br />

help distinguish pseudo-Gaucher cells from true Gaucher cells.<br />

On electron microscopy, pseudo-Gaucher cells do not contain<br />

typical tubular cytoplasmic inclusions, which are present in<br />

Gaucher cells. In addition, crystal-storing histiocytosis and<br />

sea blue histiocytosis should be considered in differential<br />

diagnosis. Macrophages with cytoplasmic crystalline<br />

inclusions are better regarded as crystal-storing histiocytes and<br />

this rare entity could be confused with Gaucher or pseudo-<br />

Gaucher cells [10]. Moreover, sea blue histiocytes should be<br />

kept in mind. However, these cells are heavily granulated with<br />

prominent vacuolation. We are reporting this case to increase<br />

the awareness among hematologists and hematopathologists <strong>of</strong><br />

this rare association to avoid misdiagnosis. We also would like<br />

to highlight that the presence <strong>of</strong> pseudo-Gaucher cells in bone<br />

marrow should not be overlooked as they might be obscuring<br />

an underlying pathology. Awareness <strong>of</strong> possible associations,<br />

appropriate immunohistochemistry, and relevant additional<br />

investigations based on clinical findings are necessary for final<br />

diagnosis.<br />

To the Editor,<br />

Solid organ transplant rejection is still a problem despite<br />

the use <strong>of</strong> immunosuppressive therapy. The currently available<br />

regimens for transplant rejection may predispose patients<br />

to malignancies such as nonmelanoma skin cancers and<br />

opportunistic infections [1]. Extracorporeal photopheresis<br />

(ECP) is a leukapheresis-based immunomodulatory therapy<br />

in which lymphocytes collected from the patient are incubated<br />

with 8-methoxypsoralen, a photosensitizing agent, in the<br />

presence <strong>of</strong> UV-A radiation and then reinfused into the patient<br />

[2]. Here we report a case <strong>of</strong> severe refractory cardiac allograft<br />

rejection that was successfully treated by ECP.<br />

A 47-year-old man presented with severe decompensated<br />

heart failure and hemodynamic compromise 13 months<br />

after heart transplantation. Ejection fraction was 25% with<br />

transthoracic echocardiography. After immediate therapy<br />

with positive inotropes and diuretics, diagnostic coronary<br />

angiography, right heart catheterization, and endomyocardial<br />

biopsy were performed. Coronary angiography revealed no<br />

obstructive coronary artery disease. The endomyocardial<br />

biopsy showed perivascular and interstitial lymphocytic<br />

inflammatory infiltrate with sparse eosinophils in 2 separate<br />

locations that were identified as moderate acute cellular<br />

rejection (ISHLT 2R). Cyclosporin A level was 150 ng/<br />

mL. Methylprednisolone pulses (1 g/day) for 3 days and<br />

equine anti-thymocyte globulin (Atgam) at 15 mg/kg/<br />

day were administered for induction therapy. Due to the<br />

deterioration <strong>of</strong> clinical status and intervening pneumonia,<br />

immunosuppressive therapy was ceased and ECP was planned.<br />

Figure 1. Endomyocardial biopsy specimen demonstrated<br />

endocardial lymphocytic aggregate.<br />

ECP sessions were performed twice a week for 2 months.<br />

After therapy the patient became minimally symptomatic<br />

with an ejection fraction <strong>of</strong> 50%. Repeated endomyocardial<br />

biopsy demonstrated lymphocytic aggregation confined to<br />

the endocardium, which was interpreted as Quilty effect, and<br />

remission <strong>of</strong> acute cellular rejection (Figure 1). The patient<br />

was discharged asymptomatically. Informed consent was<br />

obtained.<br />

Transplant rejection <strong>of</strong> solid organs remains an issue despite<br />

modern immunosuppressive regimens. The rate <strong>of</strong> rejection<br />

is 25% during the first year after heart transplantation [1].<br />

Özcan UÖ, et al: Extracorporeal Photopheresis in Acute Setting<br />

Turk J Hematol 2014;<strong>31</strong>:430-4<strong>31</strong><br />

Acute cell-mediated rejection is characterized by infiltration<br />

<strong>of</strong> T cells directed against the allograft [3]. Biopsy grades <strong>of</strong><br />

>2 R warrant accentuation <strong>of</strong> immunosuppression [4]. ‘Quilty<br />

effect’ refers to lymphocytic infiltration in the endocardium<br />

<strong>of</strong> cardiac allografts. Although the clinical significance <strong>of</strong><br />

the Quilty effect is not fully known, it is understood that the<br />

Quilty effect does not reflect transplant rejection.<br />

Hemodynamic compromise, persistence or recurrence<br />

<strong>of</strong> rejection, and side effects or complications associated<br />

with intensive immunosuppressive therapy necessitate<br />

alternative approaches for handling rejection. ECP is indicated<br />

for prevention <strong>of</strong> acute and chronic rejection <strong>of</strong> cardiac<br />

transplants [5,6,7]. Favorable effects were also demonstrated<br />

for secondary prevention among patients with a history <strong>of</strong><br />

acute rejection [8]. ECP is a relatively safe procedure. Serious<br />

side effects are rarely reported, most <strong>of</strong> which are related<br />

to hypotension and anemia secondary to volume changes<br />

and blood loss during the procedure. Risks <strong>of</strong> opportunistic<br />

infections or secondary malignancies have not been increased<br />

because <strong>of</strong> ECP [9]. Small studies demonstrated the benefits <strong>of</strong><br />

ECP for primary and secondary prevention <strong>of</strong> cardiac allograft<br />

rejection, but treatment for acute refractory cardiac allograft<br />

rejection is questionable because <strong>of</strong> the scarcity <strong>of</strong> data. We<br />

suggest the use <strong>of</strong> ECP for this compelling condition.<br />

To the Editor,<br />

Cyclosporine is a potent immune suppressant and prevents<br />

T-cell activation and graft-versus-host disease by inhibiting<br />

calcineurin phosphatase [1,2]. Anaphylactic reaction due to<br />

intravenous infusion is a rare side effect, reported in 0.1% <strong>of</strong><br />

patients [3,4]. Cremophor EL (polyoxyethylated castor oil),<br />

a solubilizing agent <strong>of</strong> the parenteral cyclosporine, has been<br />

blamed for hypersensitivity reactions [5]. Here we report<br />

a patient who developed anaphylaxis due to an intravenous<br />

form <strong>of</strong> cyclosporine.<br />

A 17-year-old boy, diagnosed with relapsed T-cell<br />

lymphoblastic lymphoma after achieving complete remission,<br />

underwent bone marrow transplantation from his fully<br />

matched brother. Intravenous cyclosporine (3 mg/kg/day) was<br />

started at day -1. At day +10, he developed a maculopapular rash<br />

on his trunk, fever, and weight gain, diagnosed as engraftment<br />

syndrome. His symptoms improved with intravenous<br />

methylprednisolone treatment (2 mg/kg/day). At day +14, at<br />

10 min after the start <strong>of</strong> cyclosporine infusion, he developed<br />

disseminated erythematous rash, respiratory distress, severe<br />

chest pain, and facial edema. His systolic blood pressure was<br />

within the normal range, but his pulse rate decreased to 50/<br />

min. Cyclosporine infusion was stopped and adrenaline,<br />

methylprednisolone, and pheniramine were intravenously<br />

administered. His complaints resolved within 30 min. We<br />

concluded that this reaction had occurred against the castor<br />

oil that exists in the intravenous form. Since cyclosporine<br />

treatment was crucial, we decided to give a capsule formulation<br />

that did not contain castor oil (Panosporin®). The capsule<br />

was given in a 3-dose graded challenge (25 mg, 25 mg, and<br />

50 mg with 30-min intervals) without significant reaction. In<br />

the following period he received scheduled doses without any<br />

problem. Skin tests performed with intravenous cyclosporine<br />

5 months after anaphylaxis revealed positive results in our<br />

patient, but the test was negative for the donor. Informed<br />

consent was obtained.<br />

Polyoxyethylated castor oil has been associated with severe<br />

anaphylaxis [6]. A recent report concerning cyclosporineinduced<br />

anaphylaxis revealed that 11 patients had a reaction<br />

with the intravenous form. Seven <strong>of</strong> these patients tolerated<br />

an oral formulation <strong>of</strong> cyclosporine. It was claimed that<br />

hypersensitivity reaction to one formulation <strong>of</strong> cyclosporine<br />

does not preclude the use <strong>of</strong> a different formulation [5].<br />

Some patients in the literature were reported to have allergic<br />

reactions to a parenteral form <strong>of</strong> both cyclosporine and<br />

tacrolimus attributed to castor oil, which is present in the<br />

formulation <strong>of</strong> both drugs [7,8]. Those patients had tolerated<br />

the oral formulation <strong>of</strong> cyclosporine without castor oil, as<br />

did our patient. Since the oral form <strong>of</strong> Panosporin® does not<br />

contain castor oil, we chose this drug for treatment for our<br />

patient without further reactions.<br />

Proposed mechanisms related to allergic reactions<br />

due to polyoxyethylated castor oil include IgE-mediated<br />

hypersensitivity, complement activation, and mast cell<br />

degranulation [5]. Our patient had a positive intradermal<br />

test for intravenous cyclosporine including polyoxyethylated<br />

castor oil. The positivity <strong>of</strong> the intradermal test suggested<br />

an IgE-mediated reaction. Interestingly, intensive immune<br />

rare reaction to castor oil [7]. In conclusion, in the case<br />

<strong>of</strong> anaphylaxis with the parenteral form, oral products <strong>of</strong><br />

cyclosporine that do not contain castor oil can be tried in<br />

patients who underwent bone marrow transplantation.<br />

Acquired Hemophilia<br />

Kazanılmış Hem<strong>of</strong>ili<br />

Retired Pr<strong>of</strong>essor <strong>of</strong> Pediatrics, <strong>Hematology</strong> and Hepatology, Honorary Fellow <strong>of</strong> American Academy <strong>of</strong> Pediatrics, Honorary Member <strong>of</strong> American<br />

Pediatric Society<br />

To the Editor,<br />

I would like to highlight 3 <strong>of</strong> our patients, a 14-year-old<br />

boy and females <strong>of</strong> 4 and 41 years old [1,2] with acquired<br />

hemophilia B seen at İhsan Doğramacı Children’s Hospital<br />

(previously Hacettepe) between 1963 and 1973 among<br />

343 patients with hemophilia [3] on account <strong>of</strong> the case<br />

<strong>of</strong> acquired hemophilia A in a 78-year-old man who was<br />

successfully treated with a combined immunosuppressive and<br />

immunoadsorption approach by Bilgin et al. as reported in a<br />

recent issue <strong>of</strong> this journal [4].<br />

Two <strong>of</strong> our 3 patients with acquired hemophilia B, which is<br />

rarer than acquired hemophilia A, improved most likely due to<br />

corticosteroid administration in at least one case and without<br />

any intervention in the others. We have shown antibodies<br />

against factor VIII in more than 20% <strong>of</strong> patients with X-linked<br />

hemophilia A and extremely rarely in normal people in low<br />

titers [3]; however, very severe bleeding due to the presence <strong>of</strong><br />

AHG antibodies was not frequent.<br />

On this occasion I would rather use the term ‘hereditary’<br />

instead <strong>of</strong> ‘congenital’ hemophilia, which was used by Bilgin<br />

et al., since inheritance is not involved in most congenital<br />

disorders, such as congenital tuberculosis, syphilis, CMV,<br />

rubella infection, etc. May I also indicate that methyl<br />

prednisolone at 1 mg/kg/day may not be effective as an<br />

immunosuppressive, but 30 mg/kg/day seems to be more<br />

effective?<br />

Reply<br />

I would like to thank you for your comment and interest in my article. Firstly you are right about this subject; hemophilia is<br />

a genetic disorder. However, congenital hemophilia is a term that can be used in literature. Secondly high dose <strong>of</strong> steroid was not<br />

preferred for this patient because <strong>of</strong> his age and comorbid disease.<br />

Figure 3. Skin biopsy studies revealed 2 granulomas containing<br />

Touton giant cells and foamy histiocytes.<br />

Analysis <strong>of</strong> a skin biopsy obtained from a 42-year-old female presenting with multiple yellowish to reddish-brown nodules<br />

and plaques on the arm, chest (Figure 1), and abdomen showed that she had generalized necrobiotic xanthogranuloma (Figure<br />

3). Informed consent was obtained.<br />

A week later, she was diagnosed with IgG-kappa multiple myeloma (Figure 2).<br />

The laboratory workup showed the following: Hb: 109 g/L, Hct: 0.34 L/L, WBC: 9.5x10 9 /L, Plt: 194x10 9 /L, with normal<br />

differential white cell count. Other studied parameters included immunoglobulin IgG:1790 mg/dL (normal range: 750-1750),<br />

IgA: 279 mg/dL (normal range: 90-450), IgM: 40 mg/dL (normal range: 70-280); and kappa light chains: 1830 mg/dL (normal<br />

range: 629-1320 mg/dL).<br />

The coexistence <strong>of</strong> paraproteinemias and necrobiotic xanthogranuloma is well described (above all, monoclonal gammopathy<br />

<strong>of</strong> unknown significance), and it would seem reasonable to recommend performing at least serum electrophoresis for patients<br />

affected by these rare conditions [1].<br />

Aggressive Multiple Myeloma with Unusual Morphology<br />

Morphology in <strong>Hematology</strong><br />

Figure 1. Atypical and multinucleated plasma cell infiltration in the bone marrow aspirate (Wright’s stain, 100x).<br />

A 66-year-old male patient was admitted to the hospital with backache, fatigue, and paraesthesia and spasm in both legs. He<br />

had lower extremity numbness and bladder and bowel incontinence. Physical examination revealed the absence <strong>of</strong> bilateral lower<br />

extremity reflexes and lower extremity weakness. Magnetic resonance imaging showed a large mass extending from T8 to T9,<br />

fracture <strong>of</strong> T9, and compression <strong>of</strong> the spinal cord. Informed consent was obtained.<br />

Laboratory results at initial evaluation revealed the following: haemoglobin: 118 g/L, haematocrit: 33.5%, white blood cell<br />

count: 6.7x109/L, platelets: 192x10 9 /L, blood urea nitrogen: 7.5 mmol/L, creatinine: 113.1 µmol/L, calcium: 1.9 mmol/L, total<br />

protein: 63 g/L; albumin: <strong>31</strong> g/L; and erythrocyte sedimentation rate: 59 mm/h. Protein studies by nephelometry revealed IgA <strong>of</strong><br />

4.25 g/L (reference range: 0.7-4 g/L) and lambda light chain <strong>of</strong> 3.98 g/L (reference range: 0.9-2.1 g/L). A small monoclonal spike<br />

was present upon protein electrophoresis. Urine immunoelectrophoresis documented no monoclonal light chain. Bone marrow<br />

aspirate and biopsy were performed and the patient underwent surgical decompression and stabilisation <strong>of</strong> the thoracic spine. The<br />

bone marrow aspirate and biopsy morphology showed infiltration with atypical, multilobated, cleaved, and monocytoid nuclei<br />

plasma cells (Figures 1 and 2). The biopsy material stained positive with lambda light chain and CD138.<br />

The neoplastic plasma cells exhibit a variety <strong>of</strong> morphologies. Poorly differentiated plasma cells may show atypical<br />

morphology, making it difficult to recognise their plasma cell nature. Plasma cell morphology correlates with disease course,<br />

prognosis, and resistance to conventional treatment [1,2,3].<br />
