HIV‐1 proviral resistance mutations: usefulness in clinical practice

Abstract

The proportion of mutations detected in the DNA was statistically significantly higher than that detected in standard RNA genotyping, and these mutations persisted for at least 1 year irrespective of therapy. The pre-existence of resistance mutations did not jeopardise treatment outcome when the drug concerned was not included in the regimen. Analysis of HIV-1 DNA could be useful in chronic infections or when switching therapy in patients with undetectable viraemia.
