INTRODUCTION & AIMS: Haemophilic arthropathy (HA) is a major complication in patients with haemophilia (PWH), but the study of age-specific prevalence and severity of HA is very limited in Asian countries. MATERIALS & METHODS: This study retrospectively reviewed 146 severe- and moderate-type Taiwanese PWH aged 4-73 years, with roentgenograms of elbows, knees and ankles and calculated Pettersson scores. RESULTS: The prevalence of HA, mean number of HAs per patient and mean Pettersson scores of all the joints were 42...

FVIII inhibitors still are the major concern in treatment of haemophilia A patients by FVIII replacement therapy. Immune tolerance induction to reverse inhibitor formation fails in about 30% of treated patients. These patients face increased morbidity and mortality producing a need for new therapy strategies in the treatment of FVIII inhibitor-positive patients. Regulatory T cells are important modulators of the immune response and are also involved in the immune response to FVIII in haemophilia A patients...

INTRODUCTION: This study was conducted to evaluate the current implementation of outcome measures in routine clinical haemophilia practice and to explore and appreciate the perception of the relevance of such measures by treaters. METHODS: A survey was completed by 19 of the 26 physicians involved in the European Haemophilia Therapy Strategy Board (EHTSB). Employing an extensive inventory of outcome measures used in patients with haemophilia, information was collected about the frequency of data collection and the subjective appreciation of their importance during clinic review...

INTRODUCTION: Inhibitor development in people with haemophilia is a serious complication that may require intensive and costly interventions. The goal of inhibitor management should be permanent inhibitor eradication through immune tolerance induction (ITI), but well-designed studies are lacking and the management of patients is therefore defined by the experience and views of the clinician. OBJECTIVES: To explore the current clinical practice and outcome of ITI therapy in Europe and how this may have changed over the last decade, as well as to provide consensus recommendations to guide clinicians in their clinical practice...

INTRODUCTION: The implementation of early long-term, regular clotting factor concentrate (CFC) replacement therapy ('prophylaxis') has made it possible to offer boys with haemophilia a near normal life. Many different regimens have reported favourable results, but the optimum treatment regimens have not been established and the cost of prophylaxis is very high. Both for optimizing treatment and reimbursement issues, there is a need to provide objective evidence of both short- and long-term results and benefits of prophylactic regimens...

INTRODUCTION: Musculoskeletal impact of haemophilia justifies physiotherapy throughout life. Recently the Dutch Health Care Institute constrained their 'list of chronic conditions', and withdrew financial coverage of physiotherapy for elderly persons with haemophilia (PWH). This decision was based on lack of scientific evidence and not being in accordance with 'state of science and practice'. METHODS: In general, evidence regarding physiotherapy is limited, and especially in rare diseases like haemophilia...

BAY 81-8973 (octocog alfa; Kovaltry(®)) is an unmodified, full-length, recombinant factor VIII (FVIII) concentrate with the same amino acid sequence as Kogenate(®) FS, but produced with innovative manufacturing technologies. This narrative review discusses the clinical efficacy and tolerability of BAY 81-8973 in haemophilia A, as well as summarizing its pharmacological properties. Results of the LEOPOLD I, LEOPOLD II and LEOPOLD Kids trials demonstrated that routine prophylaxis with intravenous BAY 81-8973 was associated with a low annualized bleeding rate (ABR) in previously treated adult and paediatric patients with severe haemophilia A...

BACKGROUND: Acquired haemophilia A is caused by the development of an autoantibody to factor VIII in a person with previously normal haemostasis. The most common clinical presentation in hereditary haemophilia is intra-articular bleeding. In contrast, acquired haemophilia more commonly presents with skin, soft tissue and mucosal haemorrhages. METHODS: We present a case of a patient with idiopathic acquired haemophilia A, whose initial presentation was that of spontaneous submental and submandibular haematoma which rapidly progressed to involve multiple sites in the airway, ultimately necessitating an emergent tracheotomy...

In haemophilia A (HA) management, antidrug antibodies, or inhibitors, are a serious complication that renders factor VIII (FVIII) replacement therapy ineffective, increases morbidity and reduces quality of life for affected patients. Inhibitor development aetiology is multifactorial and covers both genetic and therapy related risk factors. Many therapy-related risk factors have proven difficult to confirm due to several confounding factors and the small study populations available. However, clinical studies indicate that e...

INTRODUCTION: Haemophilic arthropathy (HA) is a debilitating complication of haemophilia which leads to TKA in severe cases. AIM: We conducted a prospective study of the outcome of TKA in our haemophilia cohort to define the outcomes in this population and increase the cost effectiveness of the procedure in our developing country. METHODS: We reviewed patients with haemophilia who underwent TKA between April 2010 and April 2014. Patients with at least 6 months of follow-up were included...

BACKGROUND: Undergoing a major surgical intervention such as total hip arthroplasty (THA) with an underlying clotting disorder like haemophilia poses its own unique challenges. Despite the advances in factor replacement and medical management, the potential for excessive and uncontrolled haemorrhage still exists. The aim of this study was to quantify blood loss, peri-operative transfusion requirements and risk of haematoma formation in a cohort of patients with haemophilia undergoing THA...

Efmoroctocog alfa (Elocta(®), Eloctate(®), Eloctate™), a first-in-class recombinant factor VIII-Fc fusion protein (rFVIIIFc), has an extended half-life compared with conventional factor VIII (FVIII) preparations, including recombinant FVIII (rFVIII) products. It is approved for the treatment and prophylaxis of bleeding in patients with haemophilia A in multiple countries worldwide. Data accumulated from pivotal phase III studies (A-LONG in adults and adolescents aged ≥12 years; Kids A-LONG in children aged <12 years) and their ongoing extension study (ASPIRE) have demonstrated the long-term effectiveness of efmoroctocog alfa for the treatment of acute bleeding episodes, perioperative management and routine prophylaxis in previously treated males with severe haemophilia A...

INTRODUCTION: The transition into adulthood is a developmental stage within the life cycle. A chronic childhood condition can disrupt this transition and create major challenges for both the young person and his or her family. Little is known about families' experiences when living with a rare genetic disease. Therefore, the purpose of this literature review was to understand experiences of families living with a chronic childhood disease during transition into adulthood by integrating evidence...

Clinical care of patients with haemophilia (PWH) has progressed rapidly over the past decade. Current therapy has allowed patients with haemophilia to live longer and many patients are now experiencing the co-morbidities of the general population. In this review article, we focus on three common diseases states that affect PWH: chronic pain, obesity and hepatitis C. Pain has been a co-morbidity for many years and PWH often have unusual needs for chronic pain relief compared to the general population. Obesity is not only increasing in the general population but also in patients with hereditary bleeding disorders...

INTRODUCTION: Haemophilia A is an X-linked bleeding disorder characterized by a deficiency of coagulation protein factor VIII (FVIII). A challenging complication of therapeutic FVIII infusions is the formation of neutralizing alloantibodies against the FVIII protein defined as inhibitors. The development of FVIII inhibitors drastically alters the quality of life of the patients and is associated with tremendous increases in morbidity as well as treatment costs. AIM: Current clinical immune tolerance induction protocols to reverse inhibitors are lengthy, costly and not effective in all patients...

INTRODUCTION: Looking into the future is difficult and sometimes hazardous. A reliable look into haemophilia treatment in 2030 should be based on history and contemporary progress as well as dilemmas. Today, the issue of inhibitors overshadows the entire haemophilia community together with lack of treatment for large parts of the world's persons with haemophilia. AIMS: The aim of this paper was to provide a perspective on haemophilia treatment in 2030 and its provenance...
