ABSTRACT
<p><b>OBJECTIVE</b>To investigate HIV survival time and it's influencing factors among former commercial blood and plasma donors engaged in unsafe blood donation practices in China.</p><p><b>METHODS</b>HIV/AIDS cases from 8 counties (districts) in 4 provinces confirmed prior to January 24, 2006 related with former commercial blood and plasma donors were selected and data regarding infection, AIDS progression, death, and influencing factors were retrospectively collected.</p><p><b>RESULTS</b>In 530 cases of HIV infection, 334 (63.0%) cases had developed AIDS, 168 (50.3%) had received antiretroviral therapy (ART), and 152 (29.0%) had died. For the 530 cases, there was an average (10.1 +/- 1.8) years of observation from time of infection. Among 166 AIDS patients not receiving ART, average survival was 9.1 years (95% CI: 9.1 - 9.4), with an 8 year survival rate of 52.0%. Among 168 AIDS patients receiving ART, average survival was 12.1 years (95% CI: 11.9 - 12.3), with a 12-year survival rate of 80.0%. In 3 years of ART, average survival was longer in the treatment group as compared to the no treatment group with a hazard ratio for death of 12.2. Univariate analysis showed a significant difference (P < 0.05) in AIDS patient average survival based on gender, age, location, ART status, and baseline CD(4)(+) T cells count. Results from multivariate COX-regression showed that highly active ant iretroriral therapy (HAART) was the strongest protective factor for prolonging AIDS patients' survival (HR = 13.3, P = 0.00).</p><p><b>CONCLUSION</b>Although there are many factors influencing AIDS patients survival, intervention with HAART is the principle measure to prolong survival and decrease the risk of death.</p>
