Abstract
The importance of comprehensive care as a treatment strategy for patients with hemophilia is recognized worldwide. Comprehensive care entails addressing full spectrum of medical and psychological aspects impacting both patients and their families. The primary objective of comprehensive care for individuals with hemophilia is to enable them to lead their daily lives just as anyone else would. To achieve this goal, it is necessary to have a positive and collaborative approach across various healthcare disciplines. This extends beyond clinical specialists, encompassing pediatricians, hematologists, orthopedic surgeons, dental and oral surgeons, gynecologists, nurses, physical therapists, clinical psychologists, and other professionals from diverse fields. This review article discusses the current status and challenges associated with comprehensive care for patients with hemophilia. We categorize these challenges as follows: hemophilic arthritis, rehabilitation, oral care, transitioning from pediatric to adult care, addressing carrier issues, and providing psychological care. There is still substantial work to be undertaken in addressing these hurdles and advancing the quality of comprehensive care for hemophilia patients.

Abstract
INTRODUCTION The international certification of haemophilia centres in Europe is run by the European Association of Haemophilia and Allied Disorders (EAHAD) and European Haemophilia Consortium (EHC) since 2013. The centres are designated as European Haemophilia Comprehensive Care Centres (EHCCC) or European Haemophilia Treatment Centres (EHTC), based on the specific requirements which evaluate centres' ability to provide care for patients with haemophilia and allied disorders. AIM To establish the new protocol for accreditation of European Haemophilia Centres. METHODS EAHAD, in collaboration with EHC, established Accreditation Working Group with the aim to define necessary measures to safeguard quality and improvement of bleeding disorders care throughout Europe and to build a novel model for accreditation of European Haemophilia Centres. RESULTS The European guidelines for certification of haemophilia centres have been updated to guidelines for the accreditation and include all the requirements regarding facilities, laboratory and personnel needed for optimal management of novel treatment options, including the introduction of the hub-and-spoke model for delivery of gene therapy. A pilot project for the accreditation of haemophilia centres including on-site audit has been designed. CONCLUSION Implementation of the novel accreditation protocol of the haemophilia treatment and haemophilia gene therapy centres has been made to further improve the quality of care for patients with haemophilia and other inherited bleeding disorders.

Abstract
INTRODUCTION Inherited bleeding disorders (IBDs) including hemophilia, von Willebrand disease, platelet disorders, mucocutaneous bleeding disorders and coagulation factor deficiencies are rarely found and under-recognized in low and lower-middle-income countries. Some patients succumbed to serious bleeding without diagnosis and treatment during childhood. AREA COVERED Diagnosis, management, and prevention should be integrated into the existing health care system. Although some countries have not implemented appropriate health care infrastructure, an initiative plan should be set up by cooperation of experienced experts and health care providers. Identification of patients with IBDs should be started in the antenatal setting to search for females at risk of carrier state. The investigations include bleeding assessment, mixing venous clotting time, coagulogram, coagulation factor assay and mutation detection. Genotypic analysis is helpful for confirming the definite diagnosis, carrier detection as well as prenatal diagnosis for females at risk of bearing an offspring with severe bleeding manifestations. Management involves replacement therapy ranging from blood component to virus-inactivated factor concentrate. Appropriate research is an essential backbone for improving patients' care. EXPERT OPINION Effective national strategic advocacy to manage patients with IBDs requires intensive collaboration among policy makers, health care providers, patients, and family members.

Achieving access to haemophilia care in low-income and lower-middle-income countries: expanded Humanitarian Aid Program of the World Federation of Hemophilia after 5 years. Lancet Haematol 2022; 9:e689-e697. [PMID: 36055333 DOI: 10.1016/s2352-3026(22)00209-5] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 06/10/2022] [Accepted: 06/21/2022] [Indexed: 06/15/2023]
Abstract
Highly effective treatment of haemophilia A and B is primarily available to 15% of the world's population, in high-income countries. In low-income countries (LICs) and lower-middle-income countries (LMICs), morbidity and mortality are high because of greatly reduced access to diagnosis, care, and treatment. We report the challenges and impact after the first 5 years (mid-2015-2020) of the expanded World Federation of Hemophilia (WFH) Humanitarian Aid Program (HAP). WFH HAP donated coagulation products were used to treat more than 250 000 acute bleeding episodes, manage approximately 4000 surgeries, and establish bleeding preventive prophylaxis in about 2000 patients in 73 countries. Health-care providers worldwide learned optimal management of patients with complex needs through virtual and in-person training. In response to the programme, some governments increased investment in haemophilia care, including independent purchases of small amounts of treatment products. With unparalleled scope and complexity, and substantial benefits to people with haemophilia and society in general, the WFH HAP is an exemplar of partnership between for-profit and not-for-profit organisations advancing health-care equity in LICs and LMICs, which could be replicated by other organisations supporting people with different monogenic diseases.

Abstract
INTRODUCTION Currently, a few in vivo gene replacement therapies are commercially available, with many in clinical development for the treatment of some inherited monogenic diseases. These disorders arise from mutations in genes encoding essential proteins with a well understood biological function. Wide adoption of gene replacement therapies requires solid safety and efficacy profiles with demonstrable long-term durability and cost-benefit advantages vs standard therapies. AREAS COVERED This expert review outlines the challenges and opportunities in treating hemophilia, including the progression from in vivo gene therapies toward in vivo gene editing, focusing on pre-clinical and emerging clinical data for gene editing and addressing the need for sustained and durable gene expression during hepatocyte proliferation when the liver is unable to maintain steady gene expression and protein production. EXPERT OPINION In vivo gene editing in liver tissues may be able to rescue patients younger than 18 years who are not eligible for gene replacement therapies, with hemophilia as a prime example.

Abstract
Chronic platelet disorders (CPD), including chronic immune thrombocytopenic purpura (cITP), thrombotic thrombocytopenic purpura (TTP) and platelet function disorders are among the most common bleeding disorders and are associated with morbidity and mortality. The clinical phenotype and complexity of cITP is much like that of hemophilia. In cITP and hemophilia, bleeding is problematic for many, complicating employability, insurability and overall quality-of-life (QoL). While myriad drug therapies are available for cITP and hemophilia, each are variable in their effectiveness, very few (except for clotting factor concentrates for hemophilia) alter the natural history of the disorder and sometimes contribute to specific morbidities and mortality. Like in hemophilia, the management of cITP is not solely based on access to effective treatment but also includes accurate diagnosis and comprehensive care by a multidisciplinary team of specialists trained in the management of bleeding disorders. The model of comprehensive care in Hemophilia Treatment Centers (HTCs) has been recognized as highly effective, improving life expectancy for persons with hemophilia. cITP, and other CPDs, are complex disorders requiring specialized care. However, an integrated care model with a systematic and reliable population-based surveillance program does not exist. Extending the Comprehensive Care model with all its related benefits to the community of persons with cITP is sorely needed. This review will focus on cITP as a prototype chronic platelet disorder that could benefit greatly from the Comprehensive Care model.

Abstract
BACKGROUND AND OBJECTIVES The treatment of chronic illnesses requires health care professionals (HCPs) to master several nontechnical skills to meet patient care needs. This article aims to describe the rationale and the inductive process through which a self-assessment tool for the nontechnical skills of hemophilia teams was conceived, developed, and tested. METHODS Starting from an explorative analysis of hemophilia HCP work experiences, the process followed 3 phases: an in-depth analysis of hemophilia HCP skills; the questionnaire development; and a pilot study. RESULTS Using the voice of HCPs as a starting point, the tool proved to be able to identify precise cross-professional and intercultural challenges as well as related required and/or acquired skills in the hemophilia field. CONCLUSION The proposed tool may contribute to providing HCPs with strategic knowledge to successfully perform everyday practices, to improve the effectiveness of hemophilia teams and the care model adopted by their centers, and to implement intercultural research in this field. It may be used to propose ad hoc training courses targeted by challenge, in order to fill the major gaps reported by the teams, or targeted by medical specialty or country (and therefore health care system) specificity.

Abstract
BACKGROUND Quality of life (QoL) has been included as a marker of treatment effectiveness in pediatric patients with chronic diseases. We believe that frequent multidisciplinary interventions and patient education could lead to an improvement in QoL. AIMS Determine the QoL and economic impact of monthly interventions in multidisciplinary treatment. MATERIALS AND METHODS The Haemo-QoL questionnaire was applied to patients who attended the hemophilia center of the University Hospital "Dr. José Eleuterio González," Monterrey, Mexico, at the time of enrollment and 1 year later. RESULTS Male patients between 4 and 16 years diagnosed with hemophilia were included. The score results presented are based on Haemo-QoL versions that classify patients by their age group: group 1 (4 to 7 y) and group 2 (8 to 12 y). Statistical significant improvement was observed in the overall score (sociodemographic, psychosocial, etc.) after 1 year of follow-up in both groups (P<0.05). CONCLUSIONS Impact on the QoL of patients receiving this approach was favorable. Improvement was observed regardless of severity and in those who were already in prophylaxis, suggesting that this type of approach could be causing the improvement. Results support the application of multidisciplinary treatment as the gold standard, and it should be considered in all centers including those with limited resources.

Abstract
The psychosocial impact of hemophilia on activities was recently investigated in the Hemophilia Experiences, Results and Opportunities (HERO) study (675 people with hemophilia and 561 caregivers of children with hemophilia in 10 countries). The impact of hemophilia B may not be accurately reflected in the HERO results, as ~75% of respondents described issues affecting males with hemophilia A. To address the needs of this population, the Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) was developed as a pilot study in the United States in collaboration with the hemophilia community. The analysis reported here assessed engagement in recreational activities and changes to treatment regimens around activities as reported by 299 adults with hemophilia B and 150 caregivers of children with hemophilia B. Nearly all adults with hemophilia B (98%) experienced a negative impact on their participation in recreational activities due to hemophilia-related issues, and most caregivers (90%) reported that hemophilia B had a negative impact on their child's engagement in recreational activities. One of the main reasons identified for discontinuing past activities was the risk of bruising or bleeding (adults/children with hemophilia B, 49%/41%). In particular, adults with hemophilia B reported a history of activity-related bleeding, and most adults decreased their participation in high-risk activities as they aged. Substantial percentages of adults and children with hemophilia B (including mild/moderate severity) altered their treatment regimens to accommodate planned activities. These findings may help inform guidelines for individualizing treatment regimens around participation in recreational activities based on hemophilia severity, baseline factor level, and activity risk and intensity.

Abstract
INTRODUCTION Although the regular replacement of clotting factor concentrates (prophylaxis) has been well established as the standard of care for severe haemophilia, the high cost of factor concentrates has limited access to prophylaxis in countries with under-developed or developing economies. AIMS We studied the health gap that could be addressed by providing unlimited access to clotting factor concentrates with implementation of long-term prophylaxis initiated from an early age in life. METHODS We performed a cross-sectional study of a random, representative sample of boys with moderate and severe haemophilia at three haemophilia treatment centres in Sao Paulo, Brazil, and one centre in Toronto, Canada. RESULTS Canadian subjects were more often treated with prophylaxis, and began treatment at an earlier age. Fewer Canadian subjects had bleeds within the preceding 6 months (19 vs. 34, P = 0.003). Canadian subjects had lower (better) Pettersson radiographic scores (1.5 vs. 6.0, P = 0.0016), lower (better) Hemophilia Joint Health Scores (5.5 vs. 10.5, P = 0.0038), higher (better) Activity Scale for Kids scores (96.6 vs. 92.0, P = 0.033), more time spent in vigorous activity, and higher (better) social participation scores. CONCLUSIONS Our findings suggest that increasing access to clotting factor concentrates for young boys with severe haemophilia is a global imperative.

Abstract
INTRODUCTION Care for persons with haemophilia (PWH) is most commonly delivered through the integrated care model used by Hemophilia Treatment Centers (HTCs). Although this model is widely accepted as the gold standard for the management of haemophilia; there is little evidence comparing different care models. AIM We performed a qualitative study to gain insight into issues related to outcomes, acceptability, equity and feasibility of different care models operating in the US. METHODS We used a qualitative descriptive approach with semi-structured interviews. Purposive sampling was used to recruit individuals with experience providing or receiving care for haemophilia in the US through either an integrated care centre, a specialty pharmacy or homecare company, or by a specialist in a non-specialized centre. Persons with haemophilia, parents of PWH aged ≤18, healthcare providers, insurance company representatives and policy developers were invited to participate. RESULTS AND CONCLUSIONS Twenty-nine interviews were conducted with participants representing 18 US states. Participants in the study sample had experience receiving or providing care predominantly within an HTC setting. Integrated care at HTCs was highly acceptable to participants, who appreciated the value of specialized, expert care in a multidisciplinary team setting. Equity and feasibility issues were primarily related to health insurance and funding limitations. Additional research is required to document the impact of care on health and psychosocial outcomes and identify effective ways to facilitate equitable access to haemophilia treatment and care.

Abstract
BACKGROUND Haemophilia is a rare disease for which quality of care varies around the world. We propose data-driven indicators as surrogate measures for the provision of haemophilia care across countries and over time. MATERIALS AND METHODS The guiding criteria for selection of possible indicators were ease of calculation and direct applicability to a wide range of countries with basic data collection capacities. General population epidemiological data and haemophilia A population data from the World Federation of Hemophilia (WFH) Annual Global Survey (AGS) for the years 2013 and 2010 in a sample of 10 countries were used for this pilot exercise. RESULTS Three indicators were identified: (i) the percentage difference between the observed and the expected haemophilia A incidence, which would be close to null when all of the people with haemophilia A (PWHA) theoretically expected in a country would be known and reported to the AGS; (ii) the percentage of the total number of PWHA with severe disease; and (iii) the ratio of adults to children among PWHA standardized to the ratio of adults to children for males in the general population, which would be close to one if the survival of PWHA is equal to that of the general population. Country-specific values have been calculated for the 10 countries. CONCLUSIONS We have identified and evaluated three promising indicators of quality of care in haemophilia. Further evaluation on a wider set of data from the AGS will be needed to confirm their value and further explore their measurement properties.

Abstract
All-oral treatments of hepatitis C (HCV) have been trialled in patients with hereditary bleeding disorders and found to be effective. Further refinements of dosing and duration are being established. Importantly for patient acceptability these regimens are interferon-free. Cohort studies in older patients with haemophilia direct the need for attention to weight control, exercice, assessment of cardiovascular risk, especially hypertension and detection of osteoporosis. Where patients live a long way from a comprehensive care centre, telemedicine connections can engage centre experts with the patient and his/her local practitioners in devising and monitoring care plans.

Abstract
Hemophilia is a chronic and inherited X-linked bleeding disorder that requires life-long medical care. Hemophilia treatment is costly and complex partly because of the cost of the factor concentrates used in replacement therapy. However, the management of hemophilia is not based solely on achieving access to better treatment with safe factor concentrates; it also includes accurately diagnosing the disorder and providing specialized comprehensive care by a multidisciplinary team of specialists trained in hemophilia management. Comprehensive care for the person with hemophilia is defined as the continuous supervision of all medical and psychological aspects affecting the patient and his family and it demands the establishment of specialized centers, called Hemophilia Treatment Centers. The services that should be offered by a comprehensive hemophilia healthcare center are diverse and the multidisciplinary team should be coordinated preferably by a hematologist with the participation of other health professionals. It has been demonstrated that the benefits of establishing hemophilia centers are observed even in developing countries and that changes can be achieved when resources are re-organized, especially when education and training are provided at all levels. To reach these objectives, it is essential to have the participation of the patient and family members, and to strive to obtain the financial and legislative support from the State or Government in order to achieve a national comprehensive care program contemplating all the aspects needed for improving the quality of life for the community of patients with hemophilia and other bleeding disorders.

Abstract
Severe haemophilia results in increased mortality and poorer quality of life. Factor prophylaxis leads to a more normal life, but is very costly; most of the cost is due to the high cost of replacement factor. Despite its high cost, factor prophylaxis has been adopted throughout the developed world--even in different health care systems. We argue that there are at least five possible reasons why societies may value factor prophylaxis despite its cost: (i) it is directed towards an inherited disease, (ii) the treatment is largely directed towards children, (iii) the disease is rare and the overall cost to society is small, (iv) the treatment is preventative, and v) the high cost is largely the result of providing safe products. In an era of rising health care costs, there is a strong research agenda to establish the factors that determine the value of expensive therapies for rare diseases like haemophilia.

Abstract
Approximately 14,000 people with hemophilia are registered at the Hemophilia Federation of India; however, hemophilia remains under-diagnosed and many cases are not registered. In June 2009, the Government of Uttar Pradesh made anti-hemophilic factors available at a few centers, including the Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow. Consequently, the level of hemophilia care has improved considerably in recent times. Amongst the many challenges facing people with hemophilia, the development of inhibitors, which neutralize clotting factors provided by replacement therapy, is the most feared one. Healthcare professionals who treat people with hemophilia should not only be knowledgeable about the condition and committed to bettering the management of hemophilia, but also take responsibility for the judicious allocation of resources for various aspects of managing hemophilia. This manuscript aims to raise awareness regarding the detection and management of inhibitors in hemophilia based on the experience of a tertiary care hemophilia treatment centre in Uttar Pradesh, India.

Abstract
In vivo gene replacement for the treatment of inherited disease is one of the most compelling concepts in modern medicine. Adeno-associated virus (AAV) vectors have been extensively used for this purpose and have shown therapeutic efficacy in a range of animal models. Successful translation to the clinic was initially slow, but long-term expression of donated genes at therapeutic levels has now been achieved in patients with inherited retinal disorders and haemophilia B. Recent exciting results have raised hopes for the treatment of many other diseases. As we discuss here, the prospects and challenges for AAV gene therapy are to a large extent dependent on the target tissue and the specific disease.

Abstract
BACKGROUND The identification of pathogenic mutations in haemophilia A (HA) patients is important as a basis for genetic diagnosis and also for the assessment of clinical manifestations. METHOD We analyzed 36 inversion negative congenital HA cases (28 unrelated and 8 familial) by multiplex PCR and the conformation sensitive gel electrophoresis (CSGE) technique, followed by DNA sequencing. The pathogenicity of each of these mutations was assessed using various prediction software. RESULTS We found 17 missense, 5 deletions, 3 insertions, and 2 nonsense mutations, out of which 16 were recurrent and 11 novel. All novel substitution mutations were found to be deleterious using the prediction softwares. We also encountered a double mutation (1 novel and 1 hot-spot mutation) in a family with a strong family history. A missense mutation in heterozygous state was also detected in a female bleeder with very low factor VIII levels, probably due to extreme lyonization. CONCLUSION High heterogeneity in mutational profile has been observed in the present study. The outcome of this study would enable us to give an accurate diagnosis in all affected families by direct mutation analysis.

Abstract
Replacement of the congenitally deficient factor VIII or IX through plasma-derived or recombinant concentrates is the mainstay of treatment for hemophilia. Concentrate infusions when hemorrhages occur typically in joint and muscles (on-demand treatment) is able to resolve bleeding, but does not prevent the progressive joint deterioration leading to crippling hemophilic arthropathy. Therefore, primary prophylaxis, ie, regular infusion of concentrates started after the first joint bleed and/or before the age of two years, is now recognized as first-line treatment in children with severe hemophilia. Secondary prophylaxis, whenever started, aims to avoid (or delay) the progression of arthropathy and improve patient quality of life. Interestingly, recent data suggest a role for early prophylaxis also in preventing development of inhibitors, the most serious complication of treatment in hemophilia, in which multiple genetic and environmental factors may be involved. Treatment of bleeds in patients with inhibitors requires bypassing agents (activated prothrombin complex concentrates, recombinant factor VIIa). However, eradication of inhibitors by induction of immune tolerance should be the first choice for patients with recent onset inhibitors. The wide availability of safe factor concentrates and programs for comprehensive care has now resulted in highly satisfactory treatment of hemophilia patients in developed countries. Unfortunately, this is not true for more than two-thirds of persons with hemophilia, who live in developing countries.

Abstract
Hemophilia A and B, the congenital deficiencies of coagulation factors VIII and IX, are characterized by recurrent joint and muscle bleeding episodes and progressive musculoskeletal damage (hemophilic arthropathy). Primary prophylaxis – that is, the regular infusion of factor concentrates after the first hemarthrosis and/or before 2 years of age – is now recognized as the first-choice treatment for children with severe hemophilia. Preventing bleeding from an early age enables avoidance of the clinical impact of hemophilic arthropathy and the consequences regarding psychosocial development and quality of life for these children. Interestingly, recent data suggest a role for early prophylaxis in also preventing inhibitor development, the most serious complication of treatment in hemophilia. Secondary prophylaxis, initiated after 2 years of age or after two or more joint bleeds, aims to avoid (or delay) the progression of arthropathy. In addition, better outcomes and better quality of life have been reported with earlier treatment. This review summarizes the evidence, current clinical strategies and open issues regarding prophylxis in children with hemophilia.

Abstract
The reduced mortality, improved joint outcomes and enhanced quality of life, which have been witnessed in the developed world for patients with haemophilia, have been an outstanding achievement. Advancements in biotechnology contributed significantly through the development of improved pathogen screening, viral inactivation techniques and the development of recombinant clotting factors. These were partnered with enhanced delivery of care through comprehensive haemophilia centres, adoption of home therapy and most recently effective prophylaxis. This came at great costs to governments, medical insurers and patients' families. In addition, barriers persist limiting the adoption and adherence of effective prophylactic therapy. Biotechnology has been successful at overcoming similar barriers in other disease states. Long-acting biological therapeutics are an incremental advance towards overcoming some of these barriers. Strategies that have been successful for other therapeutic proteins are now being applied to factor VIII (FVIII) and include modifications such as the addition of polyethylene glycol (PEG) polymers and polysialic acids and alternative formulation with PEG-modified liposomes. In addition, insight into FVIII structure and function has allowed targeted modifications of the protein to increase the duration of its cofactor activity and reduce its clearance in vivo. The potential advantages and disadvantages of these approaches will be discussed.

Abstract
Comprehensive care is vital for patients with haemophilia to prevent early death and free patients from the complications that inhibit living normal lives. Experience has shown that once introduced in a country, there is a progressive restoration of normal healthy lives to the haemophilia community. Accompanying this progress is a gradual decreased dependency on the haemophilia comprehensive centre - except during brief periods when expertise contained within the comprehensive centre is mandatory for life-saving clinical management or to prevent severe morbidity. During each stage of the natural evolution of comprehensive haemophilia care in a country, challenges to the existence of the centre occur, which threaten the comprehensive treatment concept. The haemophilia community must understand this natural evolution and be prepared to work collaboratively with governments, physicians and other patients to ensure that centres retain the expertise to meet the emergent needs when they arise.

Abstract
Haemophilia A and B are inherited bleeding disorders whose diagnosis and management is generally well established and best provided by specialists in a comprehensive care setting. Patients may be put at unnecessary risk if appropriate expertise is not sought for the management of accidents and surgery. The delivery of a high quality comprehensive service to patients with bleeding disorders depends upon defined standards and a network of haemophilia centres in the UK with similar models in other countries. In developing countries, despite a shortage or absence of treatment products, development of local expertise results in an improved outlook and reduction in mortality. Optimal care for severe haemophilia includes accurate diagnosis, early and adequate factor replacement for bleeding episodes and the provision of prophylaxis from an early age to prevent joint bleeding and the consequent arthropathy. Haemophilia treatment is expensive resulting in considerable inequity in provision of care across the world. Despite decades of experience, optimal treatment levels are not robustly defined. Transfusion-transmitted infections continue to have a significant impact on patient management. The development of inhibitory antibodies seriously complicates the management both in morbidity and cost. While gene therapy has not yet produced the hoped-for cure, new technologies will produce improved products.

Abstract
People with rare, inherited chronic health conditions, such as hemophilia, face added physical, social, emotional, and fiscal challenges beyond those that are common to more prevalent chronic conditions. In 1975, a partnership among clinicians, consumers, and government agencies created a nationwide regional health delivery system that increased access to clinical care, prevention, and research, thereby improving health outcomes for people with hemophilia in the United States. Today, more than 130 Comprehensive Hemophilia Diagnostic and Treatment Centers in 12 regions serve 70%-80% of the nation's hemophilia patients. Health care leaders and advocates for other rare, expensive, chronic disorders may find that regionalization improves survival and reduces disability among affected populations. However, diverse and stable resources are needed to sustain such a model in our profit-oriented US health care arena.
