Abstract

Early virological response to HIV treatment: can we predict who is likely to experience subsequent treatment failure? Results from an observational cohort study, London, UK

Highlights

  • For people living with HIV, the first antiretroviral treatment (ART) regimen offers the best chance for a good virological response

  • For people living with HIV, the first antiretroviral therapy (ART) regimen offers the best chance for a good virological response, which, if achieved, minimizes the chance of developing resistance [1,2]

  • Several studies conducted to evaluate predictors of virological response to ART in treatment-naive patients have found an association between higher pre-ART HIV RNA viral load (VL) and increased risk of treatment failure by 6–12 months [3,4,5,6,7,8,9]

Summary

Introduction

For people living with HIV, the first antiretroviral treatment (ART) regimen offers the best chance for a good virological response. Several studies conducted to evaluate predictors of virological response to ART in treatment-naive patients have found an association between higher pre-ART HIV RNA viral load (VL) and increased risk of treatment failure by 6–12 months [3,4,5,6,7,8,9]. A few studies have evaluated the association between VL levels in the first 1–2 months of ART and subsequent virological response [3,8,9] Most of these studies considered the earlier ART calendar period (pre-2000), and results may not be applicable to those starting ART today, with newer, better tolerated or more effective drugs
