Abstract
BACKGROUND: Tenofovir (TDF)-based highly active antiretroviral therapy (HAART), as recommended by the World Health Organization guidelines for HIV-naive patients, has been limited in resource-constrained settings. The aim of this study was to evaluate the effectiveness of zidovudine-(ZDV) versus TDF-based HAART in the Yi minority region of Sichuan Province, China at a single HIV treatment center. METHODS: The primary end point was the attainment of an HIV viral load <50 copies/mL. Secondary end points included change in CD4 level, adverse reactions, mortality, and sustained virologic suppression. RESULTS: Of the 361 total participants, recipients of TDF-based HAART were more likely to achieve viral load <50 copies/mL (60% versus 46%, odds ratio [OR] = 1.7, P = .016) as well as sustained virologic suppression (61% versus 28%, OR = 3.4, P = .001). Tenofovir (adjusted odds ratio [ORadj] = 1.71, P = .025) and female sex (ORadj = 1.93, P = .003) were identified as independent predictors of achieving HIV viral load <50 copies/mL in the multivariate logistic regression analysis. CONCLUSION: Among Chinese Yi minority HIV-infected participants, TDF-based HAART was superior to ZDV-based HAART for initial treatment of HIV infection, suggesting TDF-based HAART should be the regimen of choice in China.
