 Highly active antiretroviral therapy HAART has dramatically improved prognosis and lowered morbidity and mortality rates for HIV infected patients. However, significant drug toxicities, difficulties with patient compliance to HAART regimens, and development of drug resistance highlight the need for less toxic, immune-based strategies. Aldesleukin is a synthetic protein that can increase CD4 counts; it is currently approved by the Food and Drug Administration FDA for use in patients with metastatic melanoma and renal cell carcinoma. Previous studies of aldesleukin in HIV infected patients indicated that increased CD4 counts can persist for years after aldesleukin administration, and aldesleukin given with HAART may also lead to significant lowering of viral load. This study will examine the immunologic effects of intermittent cycles of aldesleukin administered with and without HAART as compared to no therapy in HIV infected patients.
