Low Level of Transmitted HIV Drug Resistance at Two HIV Care Centres in Ghana: A Threshold Survey
Abstract
Objective: This survey sought to generate information on the presence of HIV drug-resistant strains in the locality where Ghana’s ART for HIV was first introduced.
Methods: The Ghana HIVDR threshold survey (TS) was conducted and analyzed according to WHO strategy for surveillance of HIVDR in the Eastern Region of Ghana. Sixty (60) plasma specimens were collected from 2007 to 2009 by an unlinked anonymous method from HIV seropositive pregnant women, aged between 15 to24 years, who were with their first pregnancy and ART naive. Genotyping was done as follows; Ribonucleic acid (RNA) was extracted from the samples and the protease (PR) and reverse transcriptase (RT) genes amplified and sequenced. The sequences were then analyzed for HIV drug resistance mutations using Stanford University HIV Drug Resistance Database.
Results: Only two individuals were found with major HIVDR mutations: one each in the PR and RT genes. Thus the level of HIVDR in the study population in 2009 was classified as low (< 5%).
Conclusion: As at February 2009, transmitted drug resistance was not a serious problem in the Eastern Region of Ghana. However, it is important to continue monitoring tHIVDR in order to understand the dynamics of the evolution of HIV drug resistance in the country.
