Survival analysis of hemophilia-associated AIDS cases in the US.
Using national hemophilia-associated AIDS (acquired immunodeficiency syndrome) surveillance data and the life table method of survival analysis, the median length of survival of hemophilic patients in the United States after the diagnosis of AIDS was 11.7 months; the cumulative probability of survival at one year was 49.2 +/- 2.0 percent; at two years, 28.9 +/- 2.3 percent. Patients 13-29 years of age at the time of diagnosis had the longest survival and those 60 years and older had the shortest. Patients diagnosed since 1986 survived longer than those diagnosed before 1986. Length of survival did not differ significantly by race, coagulation disorder, AIDS manifestation at the time of diagnosis, or region of residence. Seven patients survived more than 36 months after AIDS was diagnosed. These patients were similar to those surviving for a shorter duration except that they were more likely to have met only the 1987 revision of the Centers for Disease Control AIDS surveillance case definition (as opposed to the 1985 case definition). Results of this study suggest that survival among hemophilic patients after the diagnosis of AIDS is similar to that reported by other investigators for other AIDS risk groups, excluding patients with Kaposi's sarcoma.
