Concordance between HIV-2 genotypic coreceptor tropism predictions based on plasma RNA and proviral DNA

AIDS. 2013 Jan 14;27(2):292-5. doi: 10.1097/QAD.0b013e32835b8bbd.

Abstract

In this study, assessing HIV-2 tropism among 43 paired plasma/peripheral blood mononuclear cell specimens, the concordance between proviral DNA and plasma RNA genotypic tropism prediction was 74%. All the discordances were attributable to the prediction of R5 in RNA and X4/dual-mixed in DNA. HIV-2 genotypic tropism test based on proviral DNA is a suitable tool for tropism determination in HIV-2-infected patients with low or undetectable viral load.
