Brief Summary:
The purpose of this observational study is to characterize which immune system cells hide the latent reservoir of HIV by counting the number of latent HIV in different subsets of CD4 cells. Observations will also be made on other possible mechanisms of HIV persistence by looking at cellular factors such as APOBEC3 and drug transporters. The purpose of this study is to develop new strategies to reduce and possibly eliminate the latent reservoir in HIV infected adults.
Detailed Description:
Memory CD4 cells may provide a reservoir of latent HIV that cannot be completely eliminated using currently available anti-HIV medications. The overall goal of this observational study is to develop new strategies to eliminate the latent HIV reservoir in HIV infected individuals. CD4-cell subsets, cellular anti-HIV factors, and cellular drug transporters will be observed to determine which resting memory cells hide latent HIV and to determine the mechanisms responsible for the persistence of the latent HIV reservoir.
This study will last for at least 3 years. The screening visit will include medical history, contact information, urine collection, and a physical exam. Participants will be assigned to one of five groups:
* Group 1 will consist of intensively studied adults initiating potentially suppressive drug therapy. At the screening visit, Group 1 participants will be given the option to either undergo blood draws or leukapheresis for all visits.
* Group 2 will consist of intensively studied, well-suppressed adults on highly active antiretroviral therapy (HAART). At the screening visit, Group 2 participants will be given the option to either undergo blood draws or leukapheresis for all visits.
* Group 3 will consist of nonintensively studied adults initiating potentially suppressive drug therapy. Group 3 participants will undergo blood draws at all visits.
* Group 4 will consist of nonintensively studied, well-suppressed adults on HAART. Group 4 participants will undergo blood draws at all visits.
* Group 5 will consist of participants who are currently in the Merck Expanded Access Program receiving raltegravir. At the screening visit, Group 5 participants will be given the option to either undergo blood draws or leukapheresis for all visits.
For all participants undergoing blood draws only, visits will occur every 3 months for about 3 years. For patients undergoing leukapheresis, visits will occur every 6 months for about 3 years. At each visit, blood collection, documentation of current HAART, and updating of contact information will occur. Participants are encouraged to provide additional blood samples to be stored at all visits.
Participants in Groups 1, 2, or 5 may decline to be in the leukapheresis group at any time and will be given the option of continuing in the blood draw group or withdrawing completely from the study. If specimens are not obtained for any reason at any visit, participants in Groups 1, 2, or 5 will default to either Group 3 or Group 4. Antiretroviral medications will not be provided by this study.
