Occurrence of transmitted HIV-1 drug resistance among Drug-naïve pregnant women in selected HIV-care centres in Ghana

Abstract

BACKGROUND: Access to antiretroviral therapy in Ghana has been scaled up across the country over the last decade. This study sought to determine the occurrence of transmitted HIV-1 drug resistance in pregnant HIV-1 positive women yet to initiate antiretroviral therapy at selected HIV Care Centres in Ghana. METHODS: Plasma specimens from twenty-six (26) HIV seropositive pregnant women who were less than 28weeks pregnant with their first pregnancy and ART naïve were collected from selected HIV care centres in three (3) regions in Ghana. Genotypic testing was done for the reverse transcriptase gene and the sequences generated were analyzed for HIV-1 drug resistance mutations using the Stanford University HIV Drug Resistance Database. RESULTS: Resistance mutations associated with the reverse transcriptase gene were detected in 4 (15.4%) of the participants. At least one major drug resistance mutation in the reverse transcriptase gene was found in 3 (11.5%) of the women. CONCLUSION: The detection of transmitted HIV-1 drug resistance in this drug-naïve group in two regional HIV care sites is an indication of the need for renewed action in monitoring the emergence of transmitted HIV-1 drug resistance in Ghana. FUNDING: None declared.
