Interleukin-2 (IL-2) Treatment for HIV Infected Patients Who Have Interrupted Their Anti-HIV Drug Therapy

Summary

When an HIV infected person taking strong anti-HIV drugs temporarily stops taking them, viral load rises and the body's immune system is exposed to more HIV. This may lead to the body mounting a better immune response against the virus. The purpose of this study is to find out if taking interleukin-2 (also called IL-2 or aldesleukin) while stopping anti-HIV drugs for short periods of time can help patients control their HIV viral load. Study hypothesis: Patients in this study will have lower virologic rebound and will maintain their CD4 cell counts for a longer time than other patients in comparative studies.
