HIV Drug Resistance in Newly Diagnosed Young Children in the Western Cape, South Africa

Abstract

Although not clinically relevant, nonnucleoside reverse transcriptase inhibitor-associated mutations were common. Dolutegravir is currently the preferred first-line treatment for adults and CLHIV age ≥4 weeks, and although very low INSTI resistance levels have been observed in adults, limited data exist on genotyping the integrase region in children. Pretreatment INSTI resistance in children is likely to be unusual, but future surveillance, including longitudinal studies with paired mother-child resistance testing, is needed.
