Summary
A four-decade clinical experience and recent evidence from randomised controlled studies
definitively recognised primary prophylaxis, i.e. the regular infusion of factor concentrates
started after the first haemarthrosis and/or before the age of two years, as the first-choice
treatment in children with severe haemophilia. The available data clearly show that
preventing bleeding since an early age enables to avoid or reduce the clinical impact
of muscle-skeletal impairment from haemophilic arthropathy and the related consequences
in psycho-social development and quality of life of these patients. In this respect,
the aim of secondary prophylaxis, defined as regular long-term treatment started after
the age of two years or after two or more joint bleeds, is to avoid (or delay) the
progression of arthropathy. The clinical benefits of secondary prophylaxis have been
less extensively studied, especially in adolescents and adults; also in the latter
better outcomes and quality of life for earlier treatment have been reported. This
review summarises evidence from literature and current clinical strategies for prophylactic
treatment in patients with severe haemophilia, also focusing on challenges and open
issues (optimal regimen and implementation, duration of treatment, long-term adherence
and outcomes, cost-benefit ratios) in this setting.
