BACKGROUND/OBJECTIVE: HIV infection affects infant growth adversely. Breast-milk substitutes are recommended to prevent postnatal HIV transmission when safe and available. We evaluated the effect on growth of an increased caloric-density milk-based formula in infants born to HIV-infected women in the U.S. and Latin America. METHODS: PACTG247 randomized 2097 infants £17d old and ³1.8kg in a double-blind trial of 26-kcal/oz compared with standard 20-kcal/oz infant formula. HIV-DNA-PCR was performed at study week (SW)4, CD4+-count at SW8, and anthropometry at each visit. Tolerability was assessed by caregiver report. Preliminary analysis was performed on data through SW8 from uninfected infants only. Growth measures were compared by t-test and linear regression, qualitative treatment differences by Fisher's exact test, and CD4+-count distributions by Wilcoxon's test. RESULTS: Forty infants were HIV-infected. Of those remaining, 1027 received 26-kcal/oz formula and 1030 received standard formula. Treatment groups were comparable at baseline and in proportions lost to follow-up (11.4% vs. 10.5%) and completing treatment (77.6% vs. 78.3%). Weight growth (mean±SE) but not length or head circumference was greater with 26-kcal/oz (5.29±0.02 vs. 5.20±0.03kg at SW8, p=0.01). No significant difference in tolerability or median CD4+-count was found. Differences with 26-kcal/oz formula were greater among infants at international sites (280g in weight and 1.0cm in length at SW8, both p=0.01). CONCLUSION: Increased caloric-density formula feedings can increase growth over 8 or fewer weeks and are well tolerated in HIV-exposed newborns. Effects in HIV-infected infants specifically and beyond SW8 remain to be determined as this ongoing study completes follow-up and analysis. Similar interventions where feasible could provide a multifactorial effort to improve infant growth and prevent breast-milk HIV transmission.
