Effect of Intermittent Aldesleukin Treatment With or Without Anti-HIV Drugs in HIV Infected People
Summary
The purpose of this study is to determine the effect of short cycles of recombinant interleukin-2 (also known as rIL-2 or aldesleukin) given with or without anti-HIV drugs in HIV infected patients. The effects will be compared with a study group that receives no IL-2 or antiretroviral therapy. Study hypothesis: Intermittent aldesleukin, when given without antiretroviral therapy to patients with early HIV infection, will produce no change in HIV viral load and increases in CD4+ T lymphocyte counts comparable to aldesleukin administered with antiretrovirals.
