Haemophilia 2002: emerging risks of treatment.
Haemophilia care and treatment products have greatly improved over the past 2 decades. Transitions in treatment produced by these changes were accompanied by the emergence of unexpected risks and new complications. In order to provide the best comprehensive care to patients with haemophilia, healthcare providers periodically need to re-evaluate and adjust their management and therapeutic products to prevent or minimize the effects produced by the emerging issues. For example, reducing the effects of infectious agents remains the highest priority for the haemophilia community because of the high level of morbidity and mortality that has resulted from earlier therapeutic agents. In many countries, the goal has been to achieve absolute zero risk for infectious agents. In some instances, the screening procedures to achieve these goals reduced the availability of plasma needed for manufactured derivatives and produced another emerging risk, shortages of clotting factor preparations. Similarly, better diagnostic methods identified other potential agents that were not inactivated by current technology. Likewise, immune tolerance regimens and the prophylactic management of haemophilia introduced different therapeutic delivery systems with their own risks. The drugs used to manage diseases such as human immunodeficiency virus (HIV), which were transmitted by products manufactured before mid-1980, create their own set of risks for this community. Topical emerging risks of treatment, including variant Creutzfeldt-Jakob disease, an assessment of its risks and impact, the complications of using indwelling catheters, and the role of protease inhibitors used to treat HIV may have on bleeding complications of haemophilia are discussed.
