Abstract
In 1967, once urgent blood requirements had been resolved in La Paz Hospital, Madrid, Spain, and adequate supplies of plasma for cryoprecipitation, therefore, being available, a Hemophilia Unit (later Hemophilia Center) was set up to attend to the comprehensive care of hemophilia patients and patients with other coagulopathies. This Center covers a regional area and also a national area for referrals and normally attends 600 patients. In this Center the Spanish Social Security Hemophilia Association was created. In 1983 the first cases of AIDS appeared, occasioning the change from standard factor VIII concentrates to the heat-treated concentrates that had recently appeared on the market. At present the Center is responsible for the medical attention of those hemophilia patients affected by HIV.
