title: Survival of hemophilic males with acquired immunodeficiency syndrome with and without risk factors for AIDS other than hemophilia.
abstract: Between January 1, 1981, and June 30, 1990, 1,514 hemophilia-associated acquired immunodeficiency syndrome (AIDS) cases in males were diagnosed in the United States. In 1,394, hemophilia was reported as the sole risk factor. For an additional 120, other risk factors were reported: of 101 of these, 40 had homosexual/bisexual activity, 53 had a history of intravenous drug use, and 8 had both of these risk factors. We examined the demographic data and the survival data of two principal groups: males for whom hemophilia was the sole reported risk factor for human immunodeficiency virus (HIV) exposure, and hemophilic males for whom homosexual/bisexual activity, intravenous drug use, or both of these additional risk factors were reported. The survival curves showed marginal differences between the hemophilia-only and the multiple risk groups; the median survival times were 13.1 and 14.6 months, with the cumulative probability of survival at 1 year as 52.7% and 54.0%, respectively. Kaposi's sarcoma was among AIDS indicator diseases more commonly found in the multiple risk factor group. Pneumocystis carinii pneumonia was the sole reported diagnosis indicative of AIDS for 34.4% of those in the hemophilia-only group, compared with 20.8% of those with multiple risk factors. The principal demographic difference between the two groups was the age distribution; those in the multiple risk factor group were primarily between 20 and 44 years of age. Restricting the analysis to those between 20 and 44 years resulted in a slightly longer survival time in the hemophilia-only group and no appreciable difference between the disease distributions and survival curves of the two groups.
