In HIV-infected subjects with haemophilia, CD4 counts seem to fall more slowly in those on high-purity factor VIII (FVIII) than on intermediate-purity product. We evaluated whether risks for AIDS or death were associated with either product among 411 HIV-infected individuals. The relative hazard of AIDS was slightly elevated for both current (1.34) [corrected] and cumulative (1.01 per month) use of high-purity products (neither significant). The corresponding hazards for death were 1.49 and 1.03 (neither significant). Thus we found no evidence that high-purity FVIII concentrates retard the development of AIDS.
