HIV: new drugs, new guidelines

Purpose of reviewThis review discusses recent changes in HIV treatment guidelines, focussing on the optimal time for starting antiretroviral therapy (ART) in chronic asymptomatic infection, and treatment options for ART-naive patients.Recent findingsUnderstanding of HIV pathogenesis has progressed significantly, with a growing appreciation of the role of HIV replication in causing inflammation and promoting both AIDS and non-AIDS diseases. Early suppression of HIV replication with ART benefits the individual, and by reducing transmission and promoting engagement with care also brings public health benefits. For years, efavirenz-based ART was favoured by treatment guidelines, reflecting unsurpassed performance in clinical trials. New treatment options show high efficacy and safety and include single-tablet coformulations for once-daily dosing to improve convenience. Recent data have demonstrated superiority over efavirenz of regimens based on rilpivirine in patients with low pre-ART HIV-1 RNA load and raltegravir or dolutegravir regardless of the viral load.SummarySome guidelines now recommend starting ART regardless of CD4 cell counts, whereas others take a more cautious approach pending results from studies that are testing the clinical benefit of early therapy. New treatment options allow therapy to be tailored to the patient's circumstances and are suitable for early ART initiation.
