Detailed Description:

The study will be conducted at the University of North Carolina in Chapel Hill, NC and Duke University in Durham, NC. The investigators plan to enroll up to 44 participants who will be enrolled for 96 weeks and will receive DTG/3TC/ABC FDC.
The investigators propose to evaluate the efficacy and time to viral suppression with DTG/3TC/ABC FDC as initial therapy for AHI (acute HIV infection), as well as the feasibility of prompt administration using a rapid HLA-B57 (human leukocyte antigen) screening antibody assay. In addition to validating the restriction of RCI (resting cell infection) by ART (antiretroviral therapy) including a DTG-based regimen initiated during AHI, the investigators will seek correlations between low RCI, residual GALT (gastrointestinal associated lymphoid tissue) HIV expression, and measures of immune activation. The investigators hypothesize that rapid reduction in plasma viremia with this regimen will limit the area under the pre-ART viral load curve, and thus reduce the latent reservoir size as measured by a viral outgrowth assay one to two years following ART start, and as compared with the latent reservoir size in acutely infected individuals started on regimens without an integrase inhibitor based regimen. In addition, the investigators will examine the longitudinal impact of the proposed integrase-based regimen initiated during the acute period on immune activation through week 96. If residual viral expression and persistent immune dysfunction is related to the burden of the latent viral reservoir (and presumably its periodic activation) these abnormalities should be ameliorated by early ART with rapid viral suppression. The investigators hypothesize that earlier treatment coupled with more rapid ART-mediated virus suppression will be associated with better long-term T cell function, specifically better T cell function after 2 years of durable HIV suppression.
