Azidothymidine (AZT) in the Treatment of Symptomatic HIV-1-Infected Hemophiliacs

Abstract
Twenty-one immunodeficiency virus 1 (HIV 1)-positive hemophilic patients were treated with Azidothymidine (AZT) for symptomatic HIV infection. The median observation period was 20.5 months. At 25 months the probability of survival was 82%, the probability of progression of disease from CDC III or IV C2 to IV C1 (AIDS) was 20% in patients on continuous AZT treatment and 50% in patients with intermption of treatment. Three patients developed severe leukopenia and 3 patients severe anemii during AZT treatment. In 1 patient a dose-dependent striking increase of transaminases during AZT treatment was observed. In 7 patients treatment was intermpted, in 1 patient because of anemia, in 1 because of pruritus and in 5 patients because of noncompliance. No signiticant changes in the consumption of clotting factor concentrates and number of bleeding episodes before and during AZT treatment were noted. We conclude, that both hematological and non-hematological side effects of AZT in HIV 1-infected hemophilic patientr ur. comparable to those seen in other risk groups . AzT does not increase the bleeding tendency in this patient group.
