摘　　要：Background The incidence of HIV-1-related infection d iseases and the mortality of AIDS have dramatically decreased since highly activ e antiretroviral therapy began to be used clinically in China in 1999. And we in itiated a second clinical trial using a combination of Efavirenz and Indinavir to observe the effects of the immunoreaction.Methods Twenty patients with laboratory-confirmed chronic HIV-1 infection were recruited. Blood samples were collected initially and during the weeks after initiation of treatment. Within 48 hours of blood sampling, peripheral blood plasma and mononuclear cells were separated using routine methods. HIV-1 viral load was measured in thawed plasma samples. Within 48 hours of peripheral blood sampling, CD4 + and CD8 + T cell subsets were enumerated.Results The drug regimen was efficient in reducing HIV-1 plasma viral load and increasing total CD4 + T cell counts. The percentage of CD4 + and CD8 + T cel l subsets expressing CD38 and HLA-DR activation markers was positively correlated with plasma viral load and tended to normalize.Conclusions The combination of Efavirenz and Indinavir was generally well tolerated and efficient at reducing HIV-1 RNA. Furthermore, the treatment improved the immunological function.Background The incidence of HIV-1-related infection d iseases and the mortality of AIDS have dramatically decreased since highly activ e antiretroviral therapy began to be used clinically in China in 1999.
