Efficacy and HIV drug resistance profile of second-line ART among patients having received long-term first-line regimens in rural China.

ABSTRACT: Antiretroviral therapy has significantly expanded and an increased proportion of patients have switched to second-line regimens in China. We describe the outcomes of second-line therapy among patients having received long-term first-line ART. A prospective follow-up study was conducted in rural areas in China. We compared the virological, immunological outcomes and genotypic drug resistance (DR) profiles before and after regimen switches. A total of 303 patients were enrolled, 283 (93.4%) were retained at 12 months. Of 90 participants with HIV-RNA ≥ 1000 copies/ml before switch, the proportion of viral load (VL) ≥ 1000 copies/ml at 6 and 12 months was 49.4% and 43.9%, respectively. Of 213 patients with HIV-RNA < 1000 copies/ml before switch, the proportion of VL ≥ 1000 copies/ml at 6 and 1
