A one-year clinical trial using didanosine, stavudine and nevirapine for highly active antiretroviral therapy.

Antiretroviral therapy is a key determinant in the treatment and prevention of human immunodeficiency virus (HIV) infection. Initial treatment for patients with HIV infection generally includes two nucleoside reverse transcriptase inhibitors (NRTI) and a protease inhibitor (PI) or a nonnucleoside reverse transcriptase inhibitor (NNRTI). The combination antiretroviral therapy (refers to highly active antiretroviral therapy or HAART) showed a significant effect upon reducing morbidity and mortality of HIV disease. Cao and colleagues~1 began the clinical application of HAART in 1999 and completed the first clinical trial in China using a combination of two NRTIs and one PI. The result in using combivir (AZT+3TC) and indinavir (2 NRTIs+1 PI) are consistent with those reported in the literature.~2 In this study, we report the first virological and immunological outcomes in HIV infected Chinese patients treated with a combination of didanosine, stavudine and nevirapine (2 NRTIs+1 NNRTI) for 52 weeks.
