Study Summary

This study will examine the effects of increases in HIV blood levels on the immune system. A better understanding of how HIV alters the immune response may lead to development of effective immune-based therapies against the virus. Patients 18 years of age or older with HIV-1 infection who have been receiving highly active antiretroviral therapy (HAART) may be eligible for this study. In order to study the effect of increased levels of virus on the immune system, therapy will be stopped in these patients temporarily. Therefore, only patients who have an appropriate level of understanding of the potential benefits of therapy and the risks of stopping treatment will be considered for enrollment. Pregnant women may not participate and women of childbearing potential must agree not to become pregnant during the study. Candidates will be screened with a medical history, physical exam, blood and urine tests and possibly a chest X-ray and electrocardiogram. Upon entering the study, participants will have blood tests to measure the amount of virus in the blood, CD4+ T cell counts, side effects of the medications, and how the patient s immune system responds to HIV in the test tube. White cells will be collected through leukapheresis. In this procedure, a needle is placed in an arm vein and blood flows from the vein through a tube (catheter) into a cell separator machine, where the white cells are separated from the rest of the blood by a spinning process. Some of the white cells are collected by the machine, and the rest of the blood is returned to the body through a second needle placed in the other arm. Patients will then have a physical examination and blood tests every 1 to 2 weeks and will be managed according to their viral load and CD4 cell counts as follows: Viral Load * If viral blood levels remain less than 5000 copies per milliliter, no medical intervention is planned. * If viral blood levels rise to 5,000 copies per ml or higher, patients will undergo a secon
