Abstract

A large observational study found an association between the use of the nucleoside reverse transcriptase inhibitor abacavir and an increase of cardiovascular risk in HIV-1–infected patients.1–3 Since then, different studies have reported controversial results: some cohort studies seemed to confirm the observation,4,5 whereas other more recent analyses and a meta-analysis seem to6–9 contradict this hypothesis. Currently, the major treatment guidelines warrant caution in the prescription of this drug in patients already showing a high cardiovascular risk based on traditional parameters.Nonetheless, a biological mechanism explaining the reasons for this finding has never been elucidated. Despite an initial observation of higher levels of inflammatory markers in a cross-sectional analysis of samples from 2 observational cohorts,4 subsequent longitudinal studies failed to detect significant associations between the use of abacavir and changes in the levels of cardiovascular risk biomarkers.
