Аннотация: Background Early initiation of combination antiretro-viral therapy (ART) during primary HIV-1 infection may prevent the establishment of large viral reservoirs, possibly resulting in improved control of plasma viraemia rebound after ART cessation. Methods Levels of cell-associated HIV-1 DNA and plasma HIV-1 RNA were measured longitudinally in 32 acutely and recently infected patients, who started ART ≤120 days after the estimated date of infection, and interrupted ART after 18 months (median) of continuous therapy. Averages of HIV-1 DNA and RNA concentrations present in blood 30–365 days after therapy interruption (median duration 300 days, range 195–358) were compared between patients who started ART ≤60 days after the estimated date of infection (early starters), those who started between 61 and 120 days (later starters), and, for HIV-1 RNA only, with 89 untreated participants of the Swiss HIV Cohort Study with documented seroconversion and longitudinal measurements collected 90–455 days after the first positive HIV test. Results In early ART starters, average levels of plasma HIV-1 RNA and cell-associated HIV-1 DNA after treatment interruption were 1 log 10 ( P=0.008) and 0.4 log 10 ( P=0.03) lower compared with later starters. Average post-treatment plasma HIV-1 RNA levels in early starters were significantly lower, respectively, compared with untreated controls (-1.2 log 10 ; P<0.0004). Conclusions Early treatment initiation within 2 months after HIV infection compared with later therapy initiation resulted in reduced levels of plasma viraemia and proviral HIV-1 DNA for ≥1 year after subsequent ART cessation. Plasma HIV-1 RNA levels in early starters were also significantly lower than in untreated controls.
