Brief Summary
The overall objective is to determine the influence of timing of ART initiation and alcohol consumption on HIV disease course. ART initiation immediately after HIV infection largely results in smaller HIV reservoir and lower HIV-associated systemic inflammation, which has been linked to non-AIDS morbidity and mortality. Immediate ART also reduces HIV-associated bacterial translocation and may prevent intestinal microbiome dysbiosis, that has been linked to increased systemic inflammation. Immediate intervention is not, however, generally feasible and more information is required about the consequences of starting ART at later time-points, but still early after acquisition. The study will be conducted in Lima, Peru, in a cohort of 180 MSM and transgender women (TW) with acute (Ab-, HIV RNA+) or recent (≤ 3 months) HIV infection. Alcohol use disorder (AUDIT score ≥8) is present in \~50% of HIV + participants in our cohort, four times higher than that seen among males in the general Peruvian population. Although the role of alcohol use in HIV pathogenesis and disease course remains unclear, some studies show a correlation with accelerated disease progression. The effects of alcohol resemble early post-infection changes in bacterial translocation and pro-inflammatory cytokines induced by HIV and their impact on HIV disease course before and after ART initiation remain unexplored. Specific Aim 1: To determine the relative long-term benefits of immediate vs. early vs. delayed ART initiation at 24 weeks after diagnosis. The investigators will study outcomes after 2 and 4 years in MSM and TW diagnosed with acute or recent HIV infection. Specific Aim 2: To determine the impact of alcohol use on the relative long-term benefits of immediate vs. early vs. delayed initiation of ART.

Outcome Measures
Primary Outcomes (13)
Baseline HIV DNA Reservoir: Total HIV DNA
Total HIV DNA reservoir at baseline (ART Initiation) Baseline total HIV DNA was measured in CD4+ T cells isolated from PBMC collected at the ART Initiation visit. Total DNA was quantitated using polymerase chain reaction (PCR) with primers within HIV (5'-LTR and gag).
Baseline
Two Phase Decay of HIV DNA Reservoir: Total HIV DNA
Decay of total HIV DNA was assessed in CD4+ T cells isolated from PBMC collected at 1, 2, 4, 8, 16, 24, 96 and 192 weeks (as available) from ART initiation (which occurred prior to enrollment into MERLIN). Total DNA was quantitated using polymerase chain reaction (PCR) with primers within HIV (5'-LTR and gag). The longitudinal decay in total HIV DNA was analyzed by use of a mixed-effects model from the time of ART initiation up to 192 weeks.
4 years from ART initiation
Baseline HIV DNA Reservoir: Integrated HIV DNA
Baseline integrated HIV DNA was measured in CD4+ T cells isolated from PBMC collected at the ART Initiation visit. Integrated DNA was quantitated using polymerase chain reaction (PCR) with primers within HIV (3'-LTR) and host DNA (alu).

Decay of integrated HIV DNA was assessed in CD4+ T cells isolated from PBMC collected at 1, 2, 4, 8, 16, 24, 96 and 192 weeks (as available) from ART initiation (which occurred prior to enrollment into MERLIN).. Integrated DNA was quantitated using polymerase chain reaction (PCR) with primers within HIV (3'-LTR) and host DNA (alu). The longitudinal decay in integrated HIV DNA was analyzed by use of a mixed-effects model from the time of ART initiation up to 192 weeks.
4 years from ART initiation
Baseline HIV DNA Reservoir: TILDA Stimulation
Baseline HIV DNA by TILDA stimulation was measured in CD4+ T cells isolated from PBMC collected at the ART Initiation visit. The inducible HIV reservoir (TILDA stimulation) was quantitated using a tat/rev induced limiting dilution assay (TILDA). Cells with inducible HIV proviruses were assessed by quantifying the frequency of CD4+ cells producing multiply-spliced HIV RNA after in-vitro stimulation.

The inducible HIV reservoir (TILDS stimulation) was quantitated using a tat/rev induced limiting dilution assay (TILDA). Cells with inducible HIV proviruses were assessed by quantifying the frequency of CD4+ cells producing multiply-spliced HIV RNA after in-vitro stimulation. The longitudinal decay in the inducible HIV DNA reservoir was analyzed by use of a mixed-effects model from the time of ART initiation up to 192 weeks.
4 years from ART initiation
HIV DNA Integration Sites
HIV DNA integration sites were measured for up to 4 years after initiation of ART (which occurred prior to enrollment in MERLIN). HIV DNA integration was assessed using CD4+ T cells isolated from PBMC at enrollment, ART initiation and 24, 96 and 192 weeks after ART initiation. HIV integration into the STAT5 and BACH2 genes was measured by assessing hybrid transcript structure (HIV LTR to BACH2 or STAT5 exon); hybrid transcript structure was confirmed by sequencing.
4 years from ART initiation
GI Microbiome
The GI microbiome will be assessed using 16S rRNA-based phylogenetic characterization of microbiome composition using stool specimens obtained before and after ART initiation.
4 years from ART initiation
Levels of Inflammatory Markers
Levels of inflammatory biomarkers measured in plasma by Meso Scale Discovery (MSD) and ELISA assays prior to infection and after viral load suppression.
4 years from ART initiation
Impact of Alcohol Use
High level alcohol use will be measured using self report (AUDIT Score and Quick Drinking Survey) and a blood biomarker (PEth). Alcohol use level will be included in multivariate analysis of GI Microbiome composition as well as a covariate in other analyses.
4 years from ART initiation
HIV RNA Viral Load
HIV viral load was measured in plasma at multiple timepoints beginning with the first visit after HIV diagnosis (which occurred prior to enrollment in MERLIN), using standard commercial viral load kits with a cut-off of 40 HIV RNA copies/mL. The log10 of HIV RNA copies/mL is reported. A value of 1.6 or less represent an undetectable log10 viral load (log10 \<40 copies/mL).

CD4 Count
CD4 counts were measured by flow cytometry at multiple timepoints in all participants.
