Summary.  Background: Prevention of arthropathy is a major goal of hemophilia treatment. While studies in adults have demonstrated an impact of prophylaxis on the incidence of joint bleeds and patients’ well‐being in terms of improved quality of life (QoL), it is unclear whether or not prophylaxis influences the outcome and perception of well‐ of children with hemophilia. Objective: This randomized controlled study compared the efficacy of prophylaxis with episodic therapy in preventing hemarthroses and image‐proven joint damage in children with severe hemophilia A (factor VIII <1%) over a 10‐year time period. Methods: Forty‐five children with severe hemophilia A, aged 1–7 years (median 4), with negative clinical‐radiologic joint score at entry and at least one bleed during the previous 6 months, were consecutively randomized to prophylaxis with recombinant factor VIII (25 IU kg−1 3 × week) or episodic therapy with ≥25 IU kg−1 every 12–24 h until complete clinical bleeding resolution. Safety, feasibility, direct costs and QoL were also evaluated. Results: Twenty‐one children were assigned to prophylaxis, 19 to episodic treatment. Children on prophylaxis had fewer hemarthroses than children on episodic therapy: 0.20 vs. 0.52 events per patient per month (P < 0.02). Plain‐film radiology showed signs of arthropathy in six patients on prophylaxis (29%) vs. 14 on episodic treatment (74%) (P < 0.05). Prophylaxis was more effective when started early (≤36 months), with patients having fewer joint bleeds (0.12 joint bleeds per patient per month) and no radiologic signs of arthropathy. Conclusion: This randomized trial confirms the efficacy of prophylaxis in preventing bleeds and arthropathy in children with hemophilia, particularly when it is initiated early in life.

In spite of an increased interest in the assessment of quality of life (QoL) in children, so far no instrument for children with haemophilia is available. Because of the low prevalence of the condition, such an instrument should also be cross-culturally applicable. In the study presented, a (QoL) assessment instrument for children with haemophilia (the Haemo-QoL questionnaire) was developed and tested in six countries (France, Germany, Italy, the Netherlands, Spain and the United Kingdom) for psychometric properties in 339 children with haemophilia and their parents. The Haemo-QoL is a self-reported questionnaire for children in the age ranges 4-7 (I: 21 items), 8-12 (II: 64 items), 13-16 years (III: 77 items) as well as for parent rating containing 9-11 subscales (depending on age-group versions). Psychometric testing involved the examination of reliability and validity. The three age-group versions of the Haemo-QoL had acceptable internal consistency and retest reliability values, as well as possessing sufficient discriminant and convergent validity. However, in young children when compared to older children, these indicators were less satisfactory. The Haemo-QoL full version is now available for children of three age groups and their parents and is ready for use in clinical research.

Summary.  Background: More and more people with severe hemophilia reach an old age thanks to an effective treatment. There is no information on the health status and quality of life of elderly people with hemophilia born at a time when replacement therapy was hardly available. Methods: Italian patients with severe hemophilia, aged ≥65 years and hence born in 1942 or earlier, were compared with elderly men without bleeding disorders matched for age, sex, geography and social status. The following aspects were evaluated: concomitant illness, orthopedic status, physical functioning and cognitive status. Measurements of generic and disease‐specific health‐related quality of life were also obtained, together with the presence or absence of depression. Results: Thirty‐nine patients, aged 65–78 years, were investigated; 33 had hemophilia A. All patients had started regular treatment on demand only when they were already 25–30 years of age. Patients were compared with 43 men without hemophilia, aged 65–79 years. More patients with hemophilia had chronic hepatitis B and C, HIV infection and hypertension. On the other hand, their elderly peers without hemophilia were more frequently hypercholesterolemic and had more cardiovascular diseases. Most hemophiliacs had arthropathy and worse values for physical functioning, but their cognitive status was similar to that of elderly non‐hemophiliacs. Hemophiliacs reported greater depression and lower health‐related quality of life. Conclusions: Elderly patients with hemophilia have more co‐morbidities and problems in daily living, but similar cognitive status as age‐matched non‐hemophilic peers. They have more chronic viral infections and hypertension but fewer cardiovascular diseases. These observations should help to optimize health care delivery in this increasing and neglected population of people with hemophilia.
