High frequency of primary mutations associated with antiretroviral drug resistance in recently diagnosed HIV-infected children

Abstract

A high percentage of recently diagnosed infants were found to carry primary ART resistance mutations. Limited options for ART of HIV-infected children might lead to increased HIV-associated morbidity and mortality. Thus, consideration should be given to mandatory screening for primary ART resistance before initiating therapy for infants aged < 12 months in countries where HIV mother-to-child transmission is still present, such as in Argentina. This will allow for the rationalized and individualized use of drugs and will contribute to the increased cost-effectiveness of local health systems.
