Predictors of cell-associated HIV-1 DNA over one year in very early treated infants.
2021
BACKGROUND Younger age of antiretroviral therapy (ART) initiation is associated with a smaller viral reservoir size in perinatally-acquired HIV-1 infection, but there is wide variability among early-treated infants. Predictors of this variability are not fully described. METHODS Sixty-three neonates diagnosed with HIV-1 14 days of birth. Three-quarters were infected despite maternal antenatal ART (however, only 9.5% of women had undetectable viral load closest to delivery) and 86% were breastfed. Higher infant CD4+ T-cell percentage and viral load 14 days. CONCLUSIONS Among very early treated infants, higher CD4+ T-cell percentage and viral load <100,000 copies/ml pre-ART, infection occurring in the absence of maternal antenatal ART and breastfeeding were associated with lower levels of HIV-1 DNA in the first 48 weeks of treatment.
