BACKGROUND: In China, many former plasma donors were infected with the human immunodeficiency virus (HIV) in the early-mid-1990s. Highly active antiretroviral therapy (HAART) was provided for former plasma donors beginning in 2002. The effect of HAART on mortality in this cohort has not been described. METHODS: This study is a retrospective analysis of the national HIV epidemiology and treatment databases for the period 1993-2006. All HIV-infected subjects from 10 counties with a high prevalence of HIV infection in 6 provinces were eligible. Inclusion criteria were: (1) history of plasma donation, (2) positive Western blot result, (3) clinical diagnosis of AIDS or CD4(+) cell count <200 cells/microL at any time, and (4) age >or=18 years at AIDS diagnosis. RESULTS: Of 9059 eligible subjects, 4093 met the inclusion criteria. Mean age was 41 years, 51% were male, 99% were farmers, and 87% were from Henan Province. Overall mortality decreased from 27.3 deaths per 100 person-years in 2001 to 4.6 deaths per 100 person-years in 2006. Conversely, the percentage of patient-years receiving HAART increased from 0% in 2001 to 70.5% in 2006. In a multivariate Cox proportional hazards analysis, not receiving HAART was the greatest risk factor for mortality (hazard ratio, 2.8; 95% confidence interval, 2.4-3.3). Among treated patients, those who had lower CD4(+) cell counts and higher numbers of opportunistic infections at the initiation of therapy were at greater risk of death. CONCLUSIONS: The national treatment program has significantly reduced the mortality rate among HIV-infected former plasma donors through the use of generic drugs in a rural treatment setting with limited laboratory monitoring. Treatment success can be improved through increased coverage and earlier initiation of therapy.
