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.
