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 />

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 />
practice can be informed and inspired by the very best courses<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
Turk J Hematol 2014;<strong>31</strong>:342-356<br />

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 />

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 />

Arıkan Akdağlı S, et al: Diagnosis <strong>of</strong> IFI in Hematological Malignancies<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 />
Turk J Hematol 2014;<strong>31</strong>:367-373<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 />

Özet:<br />
Amaç: Non-Hodgkin lenfoma (NHL) riski enfeksiyonlar ve çevresel ajanlarla artmış olarak ilişkilendirilmiştir. Hipotezimize<br />
göre bu faktörlere kronik olarak maruz kalmak T helper-2 (Th2) yolağını aktifler ve lenfomaya sebep olur. Bu amaçla Th2 yolağı<br />
komponentleri olan IL-10, IL-4, IgE, ve eozin<strong>of</strong>ille, NHL’nin prognostik belirteçleri arasındaki ilişkiye baktık.<br />
Gereç ve Yöntemler: Otuz bir NHL hastası ve 27 sağlıklı kontrolde IL-10, IL-4, IgE ve eozin<strong>of</strong>il değerlerine bakıldı. IL-4 ve<br />
IL-10 EASIA metodu ile ölçüldü.<br />
Bulgular: Yüksek IL-10 düzeyleri pek çok kötü prognostik özellikle, çok kısa yaşam süresi ve lenfopeni ile ilişkiliydi. Albümin<br />
açısından IL-10 ile negatif ilişki, IL-4 ile pozitif ilişki bulundu. Eozin<strong>of</strong>il ve IgE ile ilgili herhangi bir ilişki kurulamadı. Bazı<br />
hastalarda gözlenen artmış IL-4 geri planda kalmış Th2 yolağı aktivasyonunun bir ip ucu olabilir.<br />
Sonuç: Th2 yolağının NHL patogenezindeki yerini tespit etmek için farklı dizaynlarda çalışmalara ihtiyaç vardır.<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 />

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 />

Amaç: Hepsidin demir dengesinde önemli bir rol oynar. Temel olarak hepatositler tarafından üretilir ve intestinal epitel<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 />

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 />

(□—.) 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 />
mg/L, ESR: 25 mm/h, ALT: 103 U/L (normal range: 0-55),<br />
increasing concentric connective tissue in one portal tract (trichrome<br />

HBsAg, anti-HBs, anti-HCV, anti-CMV IgG, and CMV<br />
immunoglobulins were as follows: IgG: 1.27 g/L (5.5-17),<br />
by polymerase chain reaction (PCR), while he was<br />
positive for anti-CMV IgM (252.7%, normal range: 90- IgA: 0.06 g/L (0.6-3.3), IgM: 5.09 g/L (0.6-2.7), IgE: 16 IU/<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 />

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 />

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 />

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 />

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 />

<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 />

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 />

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 />

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 />
