The purpose of this study is to identify and provide immediate antiretroviral therapy to a cohort of HIV-infected individuals with very early HIV infection (estimated date of infection within the last 90 days). The primary aim of the study is to evaluate whether initiation of dolutegravir plus emtricitabine/tenofovir during acute/early HIV infection leads to protection of CD4+ T cells and other immune cells in the peripheral blood and lymphoid tissue from infection.

Official Title

Immediate Initiation of Antiretroviral Therapy During Acute HIV Infection


Although ART decreases HIV-associated mortality, it does not appear to completely restore immune health, for reasons that remain unclear. In addition, while HIV prevention approaches have led to significant successes in decreasing the incidence of new HIV infection over the past few years, the epidemic continues to grow both locally and globally. While complete eradication may not currently be feasible, a "functional cure" in which patients are able to indefinitely maintain undetectable viral loads in the absence of therapy may be an attainable immediate goal. Studying patients with early HIV infection and immediate ART will provide a unique opportunity to investigate the pathophysiology of the earliest stages of HIV infection and may help identify the virologic/immunologic predictors of a functional cure.
