Measure
HIV Positive Naive to ART
HIV subjects will receive open-label darunavir 800 mg in combination with ritonavir 100 mg tablets and fixed-dose combination viread + emtricitabine (Truvada®) to be taken once daily without regard to food. Subjects will undergo upper endoscopy, CT cardiac angiogram, intimal-medial thickening, and peripheral blood collection before and after 12 months of ART. darunavir with ritonavir and fixed-dose viread+emtricitabine daily
Normal Control Volunteers
HIV negative age-matched controls will undergo the same interventions and procedures without receiving ART at study entry and after 12 months.

PRIMARY outcome

Timeframe: Baseline, 12 months

Population: HIV negative participants underwent the procedures only once at Screening (entry). In the HIV group the comparison between before and after ART was done using a Wilcoxon signed-rank test.
