简要总结
To evaluate, in HIV-infected patients whose baseline CD4 count is 300 to 750 cells/mm3, whether an antiretroviral treatment regimen based upon clinical evaluation and CD4 counts plus HIV RNA viral load is more effective than a treatment regimen based upon clinical evaluation and CD4 counts without the use of HIV RNA viral load information. To assess relative utility of viral load testing in determining therapeutic choice by the surrogate marker of CD4 cell counts after 48 weeks of therapy.
It is hypothesized that among HIV-infected patients whose baseline CD4 count is in the range of 300 to 750 cells/mm3, those patients who incorporate initial and periodic viral RNA measurements in their therapeutic decisions will have higher CD4 counts after 48 weeks than patients whose therapeutic decisions do not incorporate initial and periodic viral RNA measurements.

It is hypothesized that among HIV-infected patients whose baseline CD4 count is in the range of 300 to 750 cells/mm3, those patients who incorporate initial and periodic viral RNA measurements in their therapeutic decisions will have higher CD4 counts after 48 weeks than patients whose therapeutic decisions do not incorporate initial and periodic viral RNA measurements.
Approximately 540 patients are stratified on the basis of baseline CD4 counts and are randomized to one of two treatment groups: 1. viral RNA treatment group or 2. non viral RNA treatment group. Treatment modification is based upon CD4 count, viral RNA levels (group 1 only) and clinical evaluation. Patients receive one of the three antiretroviral treatments:
- No antiretroviral therapy.
- Double reverse transcriptase inhibitor (RTI) therapy consisting of any two therapy combinations of: didanosine (ddI), lamivudine (3TC), stavudine (d4T) or zidovudine (ZDV), based upon the treating physician's judgment. The preferred combinations are ZDV + 3TC, d4T + 3TC or ddI + d4T.
- Triple antiretroviral therapy consisting of double antiretroviral therapy plus indinavir.
Treatment decisions are based upon a standardized algorithm as follows:
CD4 count 500-750 + viral RNA < 10,000:
