Abstract
BACKGROUND: Pre-cART (combined antiretroviral therapy) plasma viral load >500,000 copies/mL has been associated with a lower probability of achieving virological suppression, while few data about its role on maintenance of virological suppression are available. In this study we aimed to clarify whether high levels of pre-cART viremia are associated with virological rebound (VR) after virological suppression. METHODS: HIV-infected individuals who achieved virological suppression after first-line cART were included. VR was defined as the first of two consecutive viremia >50 copies/mL (VR50) or, in an alternative analysis, >200 copies/mL (VR200). The impact of pre-cART viremia on the risk of VR was evaluated by survival analyses. RESULTS: Among 5,766 patients included, 59.2%, 31.4%, 5.2% and 4.2% had pre-cART viremia ≤100,000, 100,001-500,000, 500,001-1,000,000, and >1,000,000 copies/mL, respectively. CONCLUSIONS: Pre-cART plasma viral load levels >500,000 copies/mL can identify fragile patients with poorer chance of maintaining virological control after an initial response. An effort in defining effective treatment strategies is mandatory for these patients that remain difficult to treat.
