Treatment of inherited coagulation disorders

Inherited coagulation protein deficiencies associated with bleeding diatheses may present with spontaneous bleeding early in life, or may not be recognized until the development of hemorrhage after trauma or surgery. Diagnostic evaluation with coagulation screening tests, followed by confirmation with coagulation factor assays, is essential for appropriate management. For moderate-to-severe hemophilia, treatment includes coagulation factor replacement with purified, plasma-derived coagulation factor, or in the case of hemophilia A, factor VIII concentrate produced with recombinant techniques. Increased use of pharmacologic agents such as desmopressin acetate for patients with mild hemophilia A or type 1 von Willebrand's disease has allowed physicians to treat patients without the risk of infectious complications from plasma-derived factor concentrates. In addition to the management of the inherited bleeding disorders, patients may also require management of human immunodeficiency virus infection, hepatitis, and coagulation factor inhibitors. Issues for the coming years will include continued work to ensure product safety, the role of prophylactic treatment to prevent longterm disabilities, and the application of gene therapy to the management of bleeding disorders.
