Effect of the Timing of Antiretroviral Treatment Initiation on Outcomes in Children Living With Human Immunodeficiency Virus Admitted With Severe Acute Malnutrition

Abstract

Delays in early infant diagnosis and antiretroviral treatment (ART) initiation in developing countries frequently result in malnutrition at initial presentation with associated higher mortality and delayed immune recovery. The optimal timing of ART initiation is yet to be established. Eighty-two children admitted with HIV and severe acute malnutrition (SAM) between July 2012 and December 2015 were enrolled. Patients were randomized to initiate ART within 14 days from admission (early arm) or delay ART initiation until nutritional recovery and >14 days after admission (delayed arm). All patients received a standardized treatment and feeding protocol and were followed to 48 weeks. The mean age of the patients at baseline was 23.3 months (standard deviation [SD], 27.9; range, 1.6–129 months). The mean time from admission to ART initiation was 5.6 days (SD, 4.4) in the early arm and 23 days (SD, 5.8) in the delayed arm (P < .001). There was no significant difference in mortality (P = .62), virologic response (P = .53), and anthropometric response (P = .57) between the 2 groups at 48 weeks. However, the rates of change in CD4, viral load, weight for age z score, and height for age z score occurred earlier and favored the delayed arm at early time points but were not significant at 24 and 48 months. Despite initial improved responses in the delayed arm, lack of difference in outcome at 48 weeks supports a pragmatic approach with earlier ART initiation in children living with HIV admitted with SAM. In this randomised controlled study of ART initiation in children admitted with HIV and severe acute malnutrition (SAM), despite initial improved responses in the delayed arm, lack of difference in outcome at 48 weeks supports a pragmatic approach with earlier ART initiation in children living with HIV admitted with SAM.
