|Human Immunodeficiency Virus|
Understanding whether the size and dynamics of the HIV reservoir are associated with adherence, measured by an objective biomarker, could have significant clinical and therapeutic implications for ART and HIV cure.
- First, this aim will quantify levels of CA-RNA, CA-DNA, and plasma residual viremia in suppressed, HIV infected individuals and correlate them with levels of TFV-DP in DBS as a measure of cumulate drug exposure (adherence).
- Second, this study will evaluate the changes in the HIV reservoir in relation to changes in ART adherence over time.

HIV suppressed individuals
HIV suppressed individuals on chronic ART, suboptimal adherence and exposure, measured through TFV-DP in DBS.
- Level of tenofovir diphosphate in dried blood spots associated with the size of the HIV reservoir measured by the amount of CA-RNA and CA-DNA in PBMCs. [ Time Frame: 6 months ]Evaluation of variations in ART cumulative adherence are associated with the size of the HIV reservoir and with the degree of chronic inflammation and immune activation in HIV-infected, virologically suppressed individuals.
- Level of self-reported adherence (4-day, 30-day and 3-months using a visual analog scale) associated with the size of the HIV reservoir measured by CA-RNA and CA-DNA in PBMCs. [ Time Frame: 6 months ]Evaluation of variations in ART self-reported adherence are associated with the size of the HIV reservoir and with the degree of chronic inflammation and immune activation in HIV-infected, virologically suppressed individuals.
