DEAR COLLEAGUES,<br />
On behalf of <strong>Bayer</strong> Schering Pharma, it is our pleasure to welcome you to Athens, Greece for the 2010 <strong>Hematology</strong><br />
<strong>Conference</strong>.<br />
The <strong>Conference</strong> aims to offer an innovative and interactive approach using plenary sessions and state-of-the-art lectures,<br />
which will focus on the continued efforts being made to improve the care given in the hemophilia community.<br />
The <strong>Conference</strong> faculty comprises a group of internationally renowned experts who will present data, engage in<br />
debate and lead interactive sessions in order to enhance all participants’ understanding of the importance of<br />
providing optimal care; bearing in mind the famous quote that is highly relevant in hemophilia,<br />
“Not life, but good life, is to be chiefly valued”, Socrates.<br />
Many issues involved with hemophilia care will be investigated, including prophylaxis in children and adults, the<br />
ageing person with hemophilia and sexual activity for people with hemophilia. There will also be a special lecture<br />
discussing new findings in genetics and polymorphisms.<br />
We are very excited to offer you what we feel is an interesting and stimulating program, which will be presented<br />
through a mix of plenary sessions, discussions, interactive workshops and case studies. We strongly encourage you<br />
to participate in the poster presentation session taking place during the <strong>Conference</strong>, and hope you will take the time<br />
to review the display of research posters and ask the authors any questions you may have.<br />
We look forward to meeting with you during the <strong>Conference</strong>, and hope that you commit to the discussions with the<br />
same enthusiasm that we have felt whilst developing the program.<br />
With best wishes,<br />

(IN COLLABORATION WITH TSIAMIS C, AND PANAGOPOULOU P.)<br />
Ethical issues are an inextricable part of everyday medical practice and the Hippocratic Oath, along with related<br />
documents, has been a beacon whenever faced with complex ethical concerns. However, the unprecedented<br />
scientific advances in the delivery of contemporary medical care have generated a wide range of thorny<br />
debates, as the decision making process often relies more on the availability of recent technological means, and<br />
less on the personality and the competence of the treating physician. Hence, the applicability of Ancient Greek<br />
deontological principles in Medicine might, at first glance, appear somehow shrinking.<br />
Hemophilia, a genetically determined disorder with increased morbidity and mortality, seems to be a typical<br />
medical condition for the prevention and treatment of which a spectrum of deontological controversies has<br />
arisen. Actually, the ancient Greek principles of medical ethics governing patient-physician relations, accuracy<br />
of diagnosis, responsibility of treatment and professional integrity are universal, and also apply to the medical<br />
management of hemophilia, despite the fact that the condition had not been identified. Disease-specific ethical<br />
issues in the contemporary era, for example, relate to: (a) equity in the provision of health care delivery to<br />
hemophiliacs, given the high costs of prophylactic treatment, especially in less resourced settings or in periods<br />
of financial crises; (b) risks and side effects associated with the implementation of advanced technologies in<br />
the diagnosis and treatment; (c) respect for patients’ human rights in research projects involving children or<br />
populations from developing countries; issues related to prenatal diagnosis and pregnancy interruption across<br />
the globe; and (d) cost–effectiveness of recently available treatments, such as prophylactic administration<br />
of Factor VIII, on the personal and the societal level, and even whether parameters such as “cost” should be<br />
considered when a human life is at stake? Can the fundamental right to “the highest attainable standard of<br />
health” be violated when states face financial crises?<br />
It would be rather naïve to attempt to fully address such concerns in the complex, multi-cultural, multi-religious<br />
and highly technologically dependent contemporary societies solely by trying to apply general Hippocratic<br />
concepts, such as “help or at least do not harm”; core humanistic ancient Greek Medical Ethics, however, seem<br />
to constitute the basic principles in this intricate quest.<br />

Mild hemophilia inspired two Swedish investigators to conceive of and initiate the concept of prophylaxis.<br />
Trying to change the phenotype of severe patients led the way to programs of maintaining patients in a mild<br />
state. This concept took years to be disseminated, adopted, and adapted. The QoL ability to participate as more<br />
normal people at a higher cost dovetailed with the advent of self-infusion and concentrate availability. Issues<br />
that arose were compliance, venous access, ports, infection, thrombosis, when to start, is it forever, and what<br />
of those who exposed and have joint disease.<br />
These issues have led to prospective studies to determine optimal regimens, primary versus secondary prophylaxis,<br />
how critical are trough levels, can one define early joint damage as something to prevent, and can joint progression<br />
in adults be moderated.<br />
Although prophylaxis can prevent joint disease, many PWH go without any therapy. Many unresolved issues<br />
regarding prophylaxis remain and will be addressed.<br />

THE START OF THE RUN: TUNISIA<br />
E M N A G O U I D E R<br />
After graduate studies at the University of Medicine in Tunis, Dr Emna Gouider specialized in hematology, and<br />
then joined the University career. She is currently a Professor of Biological <strong>Hematology</strong> and a member of the<br />
Tunisian Society of <strong>Hematology</strong>.<br />
Dr Gouider is responsible for the hemophilia treatment center in Tunis, where more than 300 patients with<br />
bleeding disorders are assisted. She was appointed General Director of the National Blood Transfusion Center<br />
in Tunisia.<br />
Involved for years in the Tunisian Association as member responsible for medical and scientific affairs,<br />
Dr Gouider was elected Chairperson.<br />
THE START OF THE RUN: TUNISIA<br />
Prophylaxis is the standard of care in severe hemophilia, but economic conditions limit its practice. In Tunisia,<br />
a developing country, clotting factor concentrate is now available for on demand therapy (0.3UI/capita in 2007<br />
and 0.64UI/capita in 2009). In order to stop or prevent arthropathy, which concerns about 40% of patients, we<br />
decided to introduce gradual prophylaxis. Since some patients have a weekly consumption of substitution, we<br />
aim to start prophylaxis with the equivalent amount of clotting factor concentrate consumption. Started in 2007,<br />
prophylaxis with low doses of clotting factor concentrates was initially prescribed for patients who bleed at least<br />
once a month or who have target joint. Doses and frequency of replacement therapy are adapted if necessary<br />
according to a tailored schema, in order to optimize cost effectiveness regimen. Prophylaxis was started with<br />
10 UI/kg twice a week; if this is not sufficient we move to 10UI/kg three times per week or 20 UI/kg twice a week,<br />
for A patients. A once weekly 20UI/kg dose is used for hemophilia B patients, if insufficient we move to 20UI/kg<br />
weekly or 10UI/kg twice a week. A control of inhibitors is performed every 20 injections.<br />
To date, 9 patients have needed dose-escalation in the initial schema, and we have observed less or no joint<br />
bleeds in most patients, especially those who started prophylaxis early. No patient has developed new synovitis.<br />
All patients had a better quality of life. No patients have developed inhibitors.<br />
Our conclusion is that prophylaxis should be generalized, progressively, to all patients in our country as early<br />
as possible.<br />

HALFWAY POINT: THE CzECH REPUBLIC<br />
In the Marathon, as in any race, it is not enough to just start the run. You have to have enough strength throughout<br />
the whole race, and you should not stop half way! The same is true for the development of hemophilia care.<br />
Twenty-two years ago in the former Czechoslovakia, the run for hemophilia was more than difficult. The ‘iron<br />
curtain’ was shut and uncrossable, making it almost impossible to obtain factor concentrates from the world<br />
behind it. Patients with hemophilia were only treated with FFP or Cryoprecipitate, and the total consump-<br />
tion of FVIII/year/capita was far below 1 IU. There were no home treatments available and no prophylaxis,<br />
despite the fact that the benefit of both had been well known for more than twenty years at that time<br />
(1,2)! Insufficient treatment led to the devastation of locomotory apparatus in numerous patients. In fact,<br />
the treatment was limited to in-patients interventions in the case of significant bleeds only. This situation<br />
was frustrating for both patients and caregivers. However, after the political change, known also as the<br />
‘Velvet Revolution’, the run could finally go on!<br />
The Czech Republic is home to over 10 million people, approximately 800 of which have hemophilia, and<br />
a quarter of them are children under 18 years of age. Once the factor concentrates became available for<br />
Czech patients, we started to use them for appropriate and efficient treatment “on-demand”, as well as<br />
for short term secondary prophylaxis. This made it possible to set up an ambitious program for surgical<br />
interventions (including total hip replacements) in patients who suffered from multiple target joints due<br />
to previous inadequate treatment of their disease. Based on the recommendations of WFH, the building<br />
up of the network of hemophilia centers had been initiated. Home treatment was introduced, and within<br />
several years it became available for all who needed and wanted it.<br />
Due to improved hemophilia care, as well as the remarkably improved availability of clotting factor concentrates,<br />
we were able to introduce secondary prophylaxis for children born during the late nineties. It was<br />
a major change in hemophilia care for the country! At the time we had chosen a similar approach to the<br />
Dutch regimen (3), which gave us an opportunity to offer such a treatment to all children at an affordable<br />
cost. We also started the national-wide program of summer camps for children with bleeding disorders,<br />
which became an integral part of hemophilia care and further promoted home treatment, self-application<br />
and prophylaxis within the Czech hemophilia population.<br />
Currently consumption of FVIII is 3,6 IU/year/capita in the Czech Republic. All our children are offered primary<br />
prophylaxis, which must start within the first 2 years, and not later than after the first bleed. Prophylaxis<br />
is started gradually with escalating frequency, based on the individual bleeding pattern, to reach final<br />
median dose of 24IU/kg; the factor three times a week in hemophilia A and twice a week in hemophilia B.<br />
We seldom use CVDs (Central Venous Devices) in our patients as they are often able to cope well with the<br />
treatment via peripheral veins. On this treatment, our boys with severe hemophilia bleed only 4 times/year<br />
in median (national-wide registry HemIS, 2008 data). Our data thus supports the evidence that prophylaxis<br />
has an undoubted benefit for children with hemophilia (4).<br />
The only positive consequence of the ‘iron curtain’ in the past was the low number of people with hemophilia<br />
infected with HIV (around 30, including 7 children). But this benefit was countered by the total isolation of<br />
the country from the rest of the world which is, of course, indefensible in any way! Despite the fact that<br />
few Czech people with hemophilia were endangered by blood born diseases in the past, we always aimed<br />
for the safest treatment for our patients. The vast majority of them are currently treated with high purity<br />
plasma derived concentrates, but the number of recombinant products is constantly increasing. Since 2006,<br />
all newly born children with hemophilia are commenced on recombinant products, as well as minimally<br />
treated and previously untreated pediatric patients. The switch to recombinant factor concentrates is<br />
also offered to other eligible pediatric patients. However, the final decision must always be the consensus<br />
between the hemophilia treater, patient and their family! The national-wide strategy of hemophilia care is<br />
firmly anchored within the Czech National Hemophilia Program – the multidisciplinary body which unites<br />
all of the Czech hemophilia treatment centers. A similar approach is also endorsed by the Working Group<br />
on Pediatric <strong>Hematology</strong> of the Czech <strong>Hematology</strong> and the Czech Pediatric Societies. The Czech Republic<br />
participates in many international projects focused on hemophilia care (e.g. EUHASS, ESChQoL etc…)<br />

Prophylaxis: a Marathon, Not a Sprint<br />
HALFWAY POINT: CzECH REPUBLIC<br />
Despite the progressive introduction of recombinant products, our inhibitor rate remains low (incidence of clinically<br />
significant inhibitors 6% and total incidence 14% in pediatric population). We believe that these findings<br />
are in accord with the results of the CANAL study (5). Perhaps the fact that we start prophylaxis gradually may<br />
play a certain role, as recently published by Kurnik and co-workers (6). Though it might be just the speculation,<br />
it seems to be more important “how you treat” your patient than “what you treat him with”?!<br />
On the other hand, the inhibitor has been and probably will always be a well-known complication of hemophilia<br />
treatment. Thus we have to be able to offer adequate treatment to all patients, who develop it. In the<br />
Czech Republic, ITI is the treatment of choice for children with inhibitors. Adult patients with inhibitors are<br />
mostly treated on demand with by-passing agents, and ITI is used seldom. When using ITI we follow current<br />
international experts’ consensus (7).<br />
Although “half of the run” is already behind us, there is still a lot to do. We promised to ourselves, as well as<br />
to our patients, that we would complete the marathon run; the torch has been lit and shall never go out!<br />

JAN ASTERMARK<br />
Dr Jan Astermark is an Associate Professor at the Centre for Thrombosis and Hemostasis at the Skane University<br />
Hospital in Malmö, Sweden. He is the co-editor of the International Monitor on Hemophilia, and currently serves<br />
as an Executive Committee member of the European Association of Haemophilia and Allied Disorders (EAHAD)<br />
and the Nordic Haemophilia Council.<br />
Dr Astermark is a reviewer for several hematology journals, and has published a number of original articles,<br />
review articles and book chapters in the field of hemophilia and coagulation disorders. He serves as the Principal<br />
Investigator for large international multicenter studies with a special focus on inhibitor development in<br />
hemophilia.<br />
THE FINISH LINE: SWEDEN<br />
Prophylactic treatment reaching a trough level of the deficient factor above 1 IU/dL was initiated on a small<br />
scale in Sweden in the late 1950s, when the observation was made that patients with moderate disease did not<br />
suffer from as many bleeds and had fewer affected joints than patients with severe disease. In this way, Swedish<br />
patients with hemophilia became pioneers in the area of prophylaxis, and through the years have shown improved<br />
clinical outcome and health status. Today, treatment is begun as primary prophylaxis before the age of 2 years<br />
and preferentially before the onset of joint bleeds. The initial dosing is generally 25 IU/kg once weekly, gradually<br />
escalated on an individual basis to every second day in patients with hemophilia A and 2-3 times weekly<br />
in hemophilia B. In most cases infusions are made in a peripheral vein, but in the event this poses problems, a<br />
central line, e.g. a Port-A-Cath, can be inserted. Based on experience from studies of pharmacokinetic dosing, daily<br />
prophylaxis has also been evaluated. This mode of treatment has the potential to provide improved protection<br />
against bleeds as well as lower consumption of factor concentrates. The primary obstacles to daily treatment<br />
are convenience and compliance, but for some patients this method is actually quite attractive, and becomes<br />
a natural part of daily living. This demonstrates that treatment should be individualized, not only on the basis<br />
of the bleeding phenotype, but also on the preferences and inclinations of the patient. In recent years, data<br />
suggesting that early prophylaxis may prevent the development of inhibitory antibodies through avoidance of<br />
treatment in association with danger signals have been accumulating. Whether this is indeed the case must be<br />
confirmed, but the finding further supports the initiation of early primary prophylaxis, the use of which has been<br />
State-of-the-Art for many years. Currently there is a debate surrounding the optimal time to stop prophylaxis.<br />
Hemophilia is a life-long disease with ongoing factor deficiency and risk of severe bleeds. Thus, from a logical<br />
point of view, treatment should not be postponed or stopped, but continued into adulthood. This is also common<br />
practise in Sweden. An important task for the future will be to increase the cost-effectiveness of treatment with<br />
improved modalities. The new long-acting molecules of the future will potentially be important additives. With<br />
the individualized use of these, prophylaxis will be further optimized from both a clinical and a cost perspective,<br />
and used throughout the entire lifespan.<br />

Dr Carcao is on the editorial board of several well known journals. He has been an invited lecturer on many<br />
occasions, and is the author or co-author of numerous peer-reviewed papers.<br />
CURRENT PRACTICE AND OUTCOMES<br />
Patients with severe hemophilia experience recurrent bleeds, particularly into joints, and can develop painful and<br />
disabling arthropathy [1]. Prophylaxis, defined as the regular infusion of clotting factor concentrates in order to<br />
prevent bleeding, has been shown in cohort studies [2-6] and in a prospective randomized study [7] to greatly<br />
improve musculoskeletal outcomes and quality of life of patients with severe hemophilia.<br />
In addition to all the known benefits of prophylaxis (less joint bleeding, less life threatening bleeds, better<br />
joint outcomes, improved quality of life, increased participation in physical activities including sports) another<br />
recently discovered benefit of prophylaxis, if started early, is that prophylaxis appears to reduce the risk of<br />
inhibitor development in patients with severe hemophilia A.<br />
Yet despite the myriad benefits of prophylaxis most of the world’s population of severe hemophilia patients<br />
is not on prophylaxis mainly due to the high cost of prophylaxis which is attributed almost exclusively to the<br />
cost of factor concentrates. Hence many investigators are looking at whether prophylaxis can be made less<br />
expensive while still retaining much, if not all, of the benefits of prophylaxis.<br />
Often prophylaxis has been thought as an all or none phenomenon; either a patient is on a “standard” prophylaxis<br />
regimen which in many countries tends to be the full dose regimen developed in Sweden or a patient is not on<br />
prophylaxis. Yet investigators in the Netherlands, Canada and various countries have shown that many patients<br />
do very well with much less intense prophylaxis regimens [3, 8, 9]. This is likely attributed to the phenotypic<br />
heterogeneity that exists among patients with severe hemophilia. Furthermore even within patients prophylaxis<br />
needs may vary over time [8].<br />
Less intense prophylaxis regimens likely come with less need for central venous access devices, less cost and<br />
better compliance. This is particularly the case when commencing very young children on prophylaxis.<br />
Most studies that compare the cost of treating patients on prophylaxis to the costs of treating patients on<br />
demand have generally found that prophylaxis is three times more expensive than on demand therapy mainly<br />
because patients on prophylaxis use three times more factor than patients treated on demand. Yet it is becoming<br />
appreciated that prophylaxis can be provided in much more cost-effective ways. Investigators are just now<br />
beginning to explore prophylaxis regimens involving daily infusions of small doses of factor (given first thing in<br />
the day). Considerable cost savings might be achieved with such regimens while at the same time maintaining<br />
the benefits of prophylaxis.<br />
How to get prophylaxis more widely available for the vast majority of the world’s population of hemophilia<br />
patients remains a key goal for the 21 st century. Regimens that use factor in a more cost-effective manner need<br />
to be explored to bring the benefits of prophylaxis to much of the world’s population of hemophiliacs which<br />
have so far not had access to prophylaxis.<br />

The impact of hemophilia is clinically evident through progressive arthropathy, the hallmark disease associated<br />
sequela. Prophylaxis has been proven to improve musculoskeletal outcomes in patients with severe hemophilia.<br />
Decreased bleeding rates due to use of prophylactic regimens have allowed patients to achieve a near normal<br />
lifespan and lead life styles that are often indistinguishable from the unaffected population. The overall<br />
societal and personal gain achieved by prophylaxis can be measured in part through an individual’s ability to<br />
participate in age relevant activities and overall function; examples of these activities and outcomes include<br />
school attendance, academic achievement and eventual gainful employment. In addition, health related quality<br />
of life is improved through prophylaxis yet is also dependent upon the rigor of and adherence to the regimen<br />
utilized, the need for central venous catheters, and the rate of breakthrough bleeding, and subsequent target<br />
joint development. Prophylaxis, although clearly the preferred treatment modality to achieve optimal outcome,<br />
is not universally utilized even in countries whose economies can support use of this regimen. Prophylactic<br />
regimens confer significant medical costs that include, but are not limited to, the cost of clotting factor<br />
concentrate, hospitalizations, required surgical interventions, emergency room visits, etc. These direct costs<br />
must be weighed against the costs of lost productivity and progressive arthropathy when on-demand regimens<br />
are utilized. The socio-economic aspects of prophylaxis may be viewed from either the individuals or overall<br />
societal perspective and likely differ based upon the age of the patient population. Existing data, although limited,<br />
is available on the socio-economic aspects of prophylaxis in the Pediatric population; data specific to the adult<br />
population is more limited. As prophylactic regimens have gained acceptance, a population of patients with<br />
improved outcomes have entered adolescence and early adulthood. Follow-up of these populations including<br />
evaluation of the continuation and utility of prophylaxis and its social-economic impact will provide increasing<br />
data pertinent to adult population.<br />
The use of prophylaxis in North American countries will be reviewed and specific data from the Universal<br />
Data Collection (UDC) Study presented. These data demonstrate that overall in the United States 53% of the<br />
participating population of severe hemophilia A patients of all ages utilized a prophylactic regimen. Data<br />
pertaining to the social and economic impact of prophylaxis in both pediatric and adult populations pertinent<br />
to the North American prospective will be presented.<br />

Dr Steen Carlsson earned her PhD in economics in 1999 at Lund University, Sweden. She is currently a postdoctoral<br />
research fellow in health economics at Lund University and a research director at the Swedish Institute<br />
for Health Economics, IHE, Lund, Sweden. Her research includes empirical economic analyses and evaluations of<br />
medical technology and health interventions. She is first author of three peer-reviewed publications evaluating<br />
prophylactic and on-demand treatment for severe hemophilia and one peer-reviewed cost-effectiveness analysis<br />
of bypassing agents for treatment patients with hemophilia who have developed inhibitors.<br />
Recent and on-going research includes analyses of registry data on long-term disease (hemophilia, diabetes,<br />
psoriasis) and disability (personal assistance, adults with multiple functional limitations). Dr Steen Carlsson<br />
is appointed health economist to National Guidelines for Diabetes Care at the National Board of Health and<br />
Welfare in Sweden.<br />
SOCIO-ECONOMIC ASPECTS: THE EUROPEAN PERSPECTIVE<br />
A life-long disease such as hemophilia has an impact on the daily life for the patient and also for the family.<br />
Before the introduction of replacement treatment with factor concentrates, persons with severe hemophilia could<br />
not expect to reach adulthood. The median length of life has been estimated to about 20 years [1]. Replacement<br />
treatment, and especially prophylactic treatment strategies, has changed the prospects in terms of length of<br />
life and of quality of life [2-4]. In addition, it has expanded the individual’s range of choices, i.e. increased both<br />
the possibilities of participating in the labor market and the range of possible professions. Previous findings<br />
have shown that patients with severe hemophilia on long-term prophylactic treatment starting early in life were<br />
more likely to be active on the labor market compared to patients with on-demand treatment [4].<br />
This presentation will present new results based on data on long-term socio-economic outcomes of high-dose<br />
and intermediate dose prophylaxis using longitudinal data on patients with severe hemophilia born from 1970<br />
and later in the Netherlands and in Sweden. Intermediate dose prophylaxis has been available for patients in<br />
the Netherlands since the 1970s and high-dose prophylaxis for patients in Sweden. This presently provides up to<br />
40 years follow-up of the long-term consequences of alternative prophylactic treatment strategies. The results<br />
include analyses of self-assessed quality of life and labor-market participation. The findings will also be related<br />
to the societal context in respective countries.<br />

P R A C T I C A L C H A L L E N G E S : V E N O U S A C C E S S<br />
Modern treatment for hemophilic children is based on prophylaxis and immune tolerance induction (ITI). Both<br />
treatment regimens are based on frequent infusions at early ages, therefore an adequate venous access is<br />
essential. Peripheral veins represent the best option, however, different solutions, as central venous access devices<br />
(CVADs) and arteriovenous fistulae (AVFs), can be adopted if needed. CVADs have been used in hemophiliacs,<br />
however their survival is affected by infectious complications. Among CVADs, fully implantable devices are usually<br />
preferred to external lines due to a lower infectious risk. The limited survival of CVADs may have a relevant impact<br />
on treatment outcome, especially in case of ITI where treatment interruptions are counterproductive.<br />
To overcome such drawbacks, internal AVF has been considered as an alternative option owing to a lower rate<br />
of infectious complications. Moreover, AVF is easy to use in the home setting and well accepted by children.<br />
Possible complications not preventing AVF use are postoperative hematoma and transient symptoms of distal<br />
ischemia; one case of symptomatic thrombosis has been reported so far. Long-term complications include loss<br />
of patency, aneurysmatic dilatation and, rarely, limb dysmetria and a regular follow-up is mandatory to allow<br />
early remedial intervention. Surgical dismantlement of AVF is recommended as soon as transition to peripheral<br />
veins is possible.<br />

NEW FINDINGS IN GENETICS<br />
Infusion of factor VIII (FVIII) concentrates has allowed successful management of patients with hemophilia A<br />
during the past half-century. The effectiveness of this strategy is offset by the development of alloantibodies,<br />
termed “inhibitors”, which neutralize the activity of the wild-type FVIII replacement protein. Inhibitors develop<br />
in 20% or more of patients with severe hemophilia A. Although clinical strategies for the management of<br />
patients with inhibitory FVIII antibodies have improved, these interventions are extremely expensive and not<br />
always successful. In addition, alloimmunized patients experience high levels of morbidity and mortality, and<br />
a poor quality of life.<br />
Studies carried out over the last two decades have greatly expanded our understanding of the factors that<br />
contribute to the development of inhibitors in hemophilia A patients or, in other words, to the immunogenicity of<br />
the wild-type FVIII protein(s) in replacement products. Inhibitor pathogenesis is complex and involves numerous<br />
product and patient related factors. Relatively little attention, however, has been given to the potential effect of<br />
nonsynonymous (ns)-single-nucleotide polymorphisms (SNPs) — slight differences in the human FVIII gene (F8)<br />
which code for single amino acid substitutions that do not cause hemophilia A but create structurally distinct<br />
wild-type FVIII proteins — on the development of this adverse alloimmune treatment outcome. I will discuss<br />
our recent studies demonstrating racial differences in the distribution of ns-SNPs in F8 and how these could<br />
contribute to the variable incidence of inhibitor development observed in different populations.<br />
I will also discuss the HLA class II genes and their ns-SNPs, as these loci encode the patients’ MHC-based antigen<br />
presentation repertoire for exogenous peptides and thus determine whether a given individual with any given<br />
F8 mutation type and collection of F8 ns-SNPs will or will not be able to mount an immune response to one<br />
or more existing (or future pipeline) FVIII replacement molecules. Finally, I will describe how knowledge of all<br />
this information in conjunction is necessary for the development and validation of predictive strategies that<br />
enable us to establish alternative personalized approaches for replacement, immune-tolerance induction, and<br />
(ultimately) curative gene-based therapies.<br />

Socrates and the Oracle at Delphi<br />
In Plato’s work Apology, the Oracle at Delphi stated that none<br />
were wiser than Socrates. Socrates, believing that he did not<br />
possess any wisdom, proceeded to test the statement by<br />
questioning the prominent wise-men of Athens. He concluded<br />
that man knew very little and was not wise at all. Therefore the<br />
Oracle was correct. Socrates wisdom was demonstrated by his<br />
awareness of his own ignorance.<br />

THE AGING PERSON WITH HEMOPHILIA: SETTING THE SCENE<br />
G E R R Y D O L A N<br />
Dr Gerry Dolan has been a Consultant Hematologist since 1991 and is the Lead for Hemostasis and Thrombosis<br />
at Nottingham University Hospitals, in Nottingham, UK. He is also the Hemophilia Director of the Nottingham<br />
Comprehensive Care Center.<br />
Dr Dolan received his medical degree from Glasgow University Medical School. He held training posts in internal<br />
medicine and hematology in Glasgow, Edinburgh, and Sheffield. His research interests include the molecular<br />
aspects of inherited bleeding disorders, ageing and hemophilia and outcome measures of hemophilia care.<br />
Dr Dolan is the Chairman of the European Hemophilia Therapy Standardization Board and the Chairman of the<br />
ADVANCE group. He is the current Vice-Chairman of the UK Hemophilia Center Doctors’ Organisation (UKHCDO).<br />
He is also Chairman of the UKHCDO Data Management Working Party and a member of the UKHCDO Working<br />
Parties on Transfusion-Transmitted Infection and Genetics. Dr Dolan is the Past President of the British Society<br />
for Haemostasis and Thrombosis.<br />
THE AGING PERSON WITH HEMOPHILIA: SETTING THE SCENE<br />
Life expectancy has increased for persons with hemophilia. In the early part of the last century, the prevalence<br />
of hemophilia was estimated to be only 4 per 100,000 males, while the prevalence in the 1990s was estimated<br />
to be 13-18 per 100,000 (1). More recent studies estimating life expectancy for individuals with severe hemophilia<br />
not infected with HIV in the period 1977 – 2001 have ranged from 63 years for the UK, to 70 years (Netherlands)<br />
and 73 years (Canada) (2, 3, 4). There are as yet no clear estimates of how rapidly this population will grow but<br />
Rosendaal and colleagues estimated that the numbers of severe hemophiliacs would increase by approximately<br />
20% within two generations (1) and the general consensus is that life expectancy is approaching that of the<br />
general population.<br />
Historically, the clinical management of hemophilia has been dominated by the risk of bleeding, the risk of chronic<br />
arthropathy and of transfusion-transmitted infection and most comprehensive care programs for hemophilia<br />
have been shaped by these medical issues (5). Improvements in care such as the availability of safe, effective<br />
factor concentrate and the adoption of prophylaxis have greatly reduced or eliminated these concerns. However,<br />
the risk of disease increases with age and it is likely that we will see many more individuals developing chronic<br />
illness that may have a complex interaction with their bleeding disorder. It has been estimated that 77% of<br />
individuals over the age of 65 have 2 or more chronic illnesses (6) and it is likely that older individuals with<br />
hemophilia will experience a similar pattern of health issues.<br />
Cardiovascular disease, including ischemic heart disease, hypertension and renal disease are leading causes<br />
of morbidity and mortality in older individuals. As individuals with hemophilia age, it is likely that many more<br />
individuals with these conditions will be seen. (7,8) It is important that proper screening and preventative medical<br />
interventions are introduced to the comprehensive care of individuals with hemophilia and this may necessitate<br />
a review of Comprehensive Care programs.<br />

DISEASE IN HEMOPHILIA<br />
Do persons with hemophilia (PWH) have more hypertension than the general population? And what about<br />
kidney disease, particularly what is the role of hematuria? And is there a relationship between kidney disease<br />
and hypertension?<br />
Concerning the first question (PWH and hypertension), many studies suggest that for more than 30 years PWH<br />
have more hypertension than the general population. Indeed in 1977, J. Weisz and C. Kasper (1) reported an<br />
increased prevalence (33%) of hypertension in 233 PWH. No differences in the lifetime exposure to blood products<br />
of all types were found in normotensive and hypertensive patients. In 1990 Rosendaal et al (2) confirmed that<br />
PWH had, on average, higher blood pressures than the comparison population and used hypertensive drugs<br />
twice as often. No association was found between the severity of hypertension and blood pressure. In both<br />
studies hypertension was mainly due to a higher mean of diastolic blood pressure. In a cohort of Canadian<br />
patients with mild hemophilia, 29% were hypertensive compared to 18% of the control subjects (3). Many<br />
confounding factors have to be taken into account in these retrospective analysis but Siboni et al (4) still<br />
found an increased prevalence of hypertension in severe PWH after adjusting for alcohol intake, use of pain<br />
killers and anti-HIV medication.<br />
Hematuria is common among PWH, but its long-term effects on renal function are not well-defined. In addition<br />
infection with HIV and hepatitis C, exposure to nephrotoxic agents (e.g. HAART), the presence of an inhibitor or<br />
the use of tranexamic acid may place PWH at increased risk for renal disease. In 1970, Prentice et al (5) found a<br />
large number of renal complications in PWH. Kulkarni et al (6) analyzed data collected from 3,422 PWH in six US<br />
states and found that acute and chronic renal diseases were strongly associated (among other factors) with<br />
hypertension.<br />
These data imply that blood pressure and renal monitoring should be carefully followed in PWH. At the present<br />
time it is difficult to see a clear relationship between hypertension and renal disease (influence of hypertension<br />
on renal disease and vice versa) and to establish the role of kidney bleeds. A questionnaire (H3 for Hemophilia,<br />
Hypertension and Hematuria) will be sent to ADVANCE members to compile epidemiological data on the link<br />
between hemophilia, hypertension and hematuria, in order to help generate data that will contribute to the<br />
development of guidance on the management of adult PWH.<br />

THE AGING PERSON WITH HEMOPHILIA: ASSESSING CARDIOVASCULAR RISK<br />
C E D R I C H E R M A N S<br />
Dr Cedric Hermans completed his medical training and specialization in General Internal Medicine at the<br />
school of Saint-Luc University Hospital of the Catholic University of Louvain, Belgium. He obtained his PhD<br />
in Biomedical Sciences, specializing in Toxicology, in 1999.<br />
In 2000 Dr Hermans took up a one year fellowship in the Hemophilia Center and Hemostasis Unit of the Royal<br />
Free Hospital, London. He was appointed Associate Professor at the Medical School of the Catholic University<br />
of Louvain in 2003 and Clinical Professor in 2009. He is currently heading the Division of <strong>Hematology</strong> and the<br />
Hemostasis and Thrombosis Unit of the Saint-Luc University Hospital of the Catholic University of Louvain,<br />
Brussels.<br />
Dr Hermans has published over 90 articles in international journals and is a member of several scientific<br />
societies. Presently, his main research interests lie in the area of hemostasis and thrombosis, especially<br />
clinical studies on the treatment of hemophilia, new anticoagulants, and the management of thrombosis<br />
and inherited bleeding disorders.<br />
THE AGING PERSON WITH HEMOPHILIA: ASSESSING CARDIOVASCULAR RISK<br />
Individuals with hemophilia have long been considered to be protected from cardiovascular disease and<br />
mortality. This assumption is supported by the lower cardiovascular mortality documented in different previous<br />
cohort studies, suggesting a cardiovascular protective effect of lifelong low coagulation factor levels.<br />
With longer life expectancy in patients with hemophilia, diseases associated with ageing, such as cardiovascular<br />
disease, are increasing in importance. With respect to the cardiovascular risk factors, an increased<br />
prevalence of hypertension and lower mean total cholesterol levels compared to the general population<br />
were found about 20 years ago by Rosendaal and colleagues who assessed the prevalence of cardiovascular<br />
risk factors in 95 hemophilia patients.<br />
In the absence of more recent and extensive study, one can assume that the cardiovascular risk profile of<br />
patients with hemophilia has changed over the last decades as a result of ageing, change in the pattern of<br />
comorbidities, and the adoption by most patients of the western lifestyle. In addition, one cannot rule out<br />
that the wider use of prophylaxis could to some extent mitigate the vascular protection on atherothrombosis<br />
provided by the hypocoagulability secondary to haemophilia. In this context, there is a clear need for large<br />
studies evaluating the prevalence of cardiovascular risk factors in adult and elderly patients with haemophilia.<br />
Prevention of coronary heart disease in clinical practice is based on the assessment of the individual's total<br />
burden of risk using the prevalence of multiple concurrent risk factors (Score). This risk algorithm has never<br />
56 57<br />
NOTES<br />
been validated in the hemophilia population. It therefore appears premature to use this tool to estimate the<br />
expected cardiovascular mortality in patients with hemophilia. Despite these limitations, active screening<br />
for cardiovascular risk factors should be encouraged in all patients with hemophilia. Hypertension and<br />
hyperglycemia should be carefully screened for, not only because they increase the risk for cardiovascular<br />
events, but also because they enhance the risk of microvascular disease and cerebral haemorrhage for which<br />
hemophilia has no preventive effect.<br />

UROLOGIST AND A SExOLOGIST<br />
Sexual dysfunction is common in aging men and may be exacerbated by the special medical issues and psychological<br />
problems associated with hemophilia. Sexual healthcare for men with hemophilia (MWH) requires a background<br />
understanding of common patterns of sexual function and dysfunction in the aging male, of expectable sexual<br />
complications of hemophilia and related co-morbidities, and of sexual aspects of psychological issues. A sexual<br />
history differentiates problems involving a loss of sexual desire from ejaculatory difficulties and erectile dysfunction<br />
(ED), distinguishes organic from psychogenic ED, and guides further evaluation. Physicians treating MWH<br />
should be familiar with the use of phosphodieterase-5 inhibitors as first-line treatment for ED and recognize the<br />
need for referral to specialized sexual urology and mental health professionals when appropriate. As increasing<br />
numbers of MWH reach middle age and beyond, many experience problems with sexual function, including loss<br />
of sexual desire, ejaculatory difficulties, and varying degrees of erectile dysfunction. Some of these conditions<br />
are caused by age-related biological changes in the hormones, nerves, and blood vessels responsible for male<br />
sexual function. Other sexual difficulties are specific to the medical problems associated with hemophilia, such<br />
as chronic pain, bleeding, infection with hepatitis C virus (HCV) and human immunodeficiency virus (HIV), and<br />
sexual side effects of medications. Finally, some sexual problems result from the psychological experience of<br />
living with hemophilia. For example, the burdens of medical illness, caretaking, and shame and embarrassment<br />
about having HCV and/or HIV may compromise sexual relationships and cause men to worry about being desirable<br />
to potential partners. Sexuality can be a valuable source of meaning, self-esteem, and fulfilment, and its<br />
importance to individuals with chronic illness and their partners should not be underestimated. Sexuality can<br />
also be a window into other significant health issues. Healthcare providers can do much to help MWH remain<br />
sexual. However, integration of sexual healthcare into the busy routine of office/clinic practice is not easy.<br />
Sexual healthcare for MWH requires a background understanding of common patterns of sexual function and<br />
dysfunction in the aging male, of expectable sexual complications of hemophilia and related co-morbidities, and<br />
of sexual aspects of psychological issues. Effective sexual history-taking identifies the kind of sexual disorder<br />
and directs further evaluation. When ED is diagnosed, PDE-5 inhibitors are first-line therapy. If sexual difficulties<br />
persist with treatment, referral to sexual specialists in urology and mental health care is indicated.<br />

SExUAL ACTIVITY AND PEOPLE WITH HEMOPHILIA<br />
WOET GIANOTTEN<br />
Dr Woet Gianotten graduated as an MD in the Netherlands. His spent the first part of his career concentrating<br />
on tropical medicine, with training in surgery, gynacology and obstetrics and over five years working in various<br />
places in West and East Africa.<br />
Back in the Netherlands Dr Gianotten settled in two areas; he engaged in the contraceptive aspects of reproductive<br />
health care, and the other was in sexology. He was trained as a psychotherapist and worked for 25 years in<br />
‘common sexology’, where clients usually have no somatic cause for their sexual troubles.<br />
Gradually Dr Gianotten’s medical roots directed him more to the area of ‘medical sexology’, where chronic disease,<br />
cancer, physical impairment, and medical interventions are a major cause of people’s sexual troubles. He<br />
worked up until the Dutch retirement-age as a medical sexologist in the University Medical Centers of Utrecht<br />
and Rotterdam. Nowadays his attention is concentrated on three areas of interest: oncosexology, reproduction<br />
sexology, and physical rehabilitation sexology. He still has a part-time job in a rehabilitation center.<br />
In 2008 Dr Gianotten was editor in chief of the Dutch-language book ‘Sexuality in disease and physical impairment’.<br />
He is the co-founder and a board member of the International Society for Sexuality and Cancer (ISSC) and<br />
is responsible for education. He is associate secretary of the World Association for Sexual Health (WAS).<br />
SExUAL ACTIVITY AND PEOPLE WITH HEMOPHILIA: THE PERSPECTIVES OF<br />
A UROLOGIST AND A SExOLOGIST<br />
For the majority of patients, hemophilia care professionals have developed a primary care function, covering<br />
all health problems. That is one reason why sexuality has to be integrated into their approach, and also why<br />
this topic is addressed here.<br />
For young men in the Western world, hemophilia hardly has any sexual consequences. The exception being<br />
iliopsoas; muscle bleeding as a result of (too) vigorous movements during intercourse or (too) vigorous muscular<br />
tension during masturbation.<br />
The elder generation, on the other hand, has to deal with several factors that interfere with optimal sexual<br />
function.<br />
In their early years bleeding damaged various joints. That has impaired the repertoire of sexual movements and<br />
can be accompanied by pain and disturbing noises during lovemaking.<br />
Being infected with the hepatitis C virus increases the prevalence of sexual dysfunction. The risk of getting a<br />
sexual dysfunction doubles when treated with interferon. Various factors play a role here, among which are<br />
depression and the sexual side effects of antidepressants. When interferon is combined with ribavirin antiviral<br />
therapy it can cause a decrease in testosterone (negatively influencing sexual desire).<br />
Being infected with HIV can cause additional sexual impairment. This is apparently partly a result of being<br />
seropositive, and partly a result of the HAART approach.<br />
Independent of the above mentioned reasons, elder age can be a reason for sexual disturbances. Although age<br />
itself is not a reason for less sex, the accompanying chronic disease, the changing partner and the age-dependent<br />
diminished ability to become aroused can all lead to a decreased sexual function.<br />
The most important recommendation for health professionals is: communicate! Since patients are too shy to<br />
bring up the subject of sexuality, the hemophilia health professional should proactively do so to explore existing<br />
sexual dysfunctions.<br />
There are good arguments to keep sexuality at an optimal level, not only because sexuality is an important quality<br />
of life, but also because various aspects of sexual expression clearly are accompanied by health benefits.<br />
In hemophilia the range of treatment modalities for sexual dysfunction is slightly narrowed; especially for<br />
erectile dysfunction. Vacuum therapy and intracavernous injections are contraindicated and oral medication<br />
with PDE5-inhibitors apparently can cause severe epistaxis.<br />
When needed, the hemophilia care professionals should give information on various practical aspects of<br />
sexuality. That can include suggesting suitable positions, recommending painkillers, reflect on prescribing<br />
erection enhancing medication and also referral to a sexology expert.<br />
