Effects of Two Anti-HIV Drug Combinations on the Immune Systems of HIV-Infected Patients Who Have Never Received Anti-HIV Drugs

This study will compare an anti-HIV drug combination of protease inhibitor plus a nonnucleoside reverse transcriptase inhibitor (NNRTI) to one that includes three nucleoside reverse transcriptase inhibitors (NRTIs) plus an NNRTI. NNRTIs, NRTIs, and protease inhibitors are all types of anti-HIV drugs that block the virus in some way. This study will try to find out if a treatment regimen containing a protease inhibitor plus an NNRTI has a different effect on the rise of CD4 cells compared to a treatment made up of three NRTIs plus an NNRTI. CD4 cells are cells of the immune system that fight infection. This study will also try to see if the combination of drugs used in this study is safe to use in HIV-positive patients.
