Objective: To assess the 9-month HIV-free survival of children with two strategies to prevent HIV mother-to-child transmission. Design: Nonrandomized interventional cohort study. Setting: Four public health centres in Rwanda. Participants: Between May 2005 and January 2007, all consenting HIV-infected pregnant women were included. Intervention: Women could choose the mode of feeding for their infant: breastfeeding with maternal HAART for 6 months or formula feeding. All received HAART from 28 weeks of gestation. Nine-month cumulative probabilities of HIV transmission and HIV-free survival were determined using the Kaplan-Meier method and compared using the log-rank test. Determinants were analysed using a Cox model analysis. Results: Of the 532 first-liveborn infants, 227 (43%.) were breastfeeding and 305 (57%) were formula feeding. Overall, seven (1.3%) children were HIV-infected of whom six were infected in utero. Only one child in the breastfeeding group became infected between months 3 and 7, corresponding to a 9-month Cumulative risk of postnatal infection of 0.5% [95% confidence interval (CI) 0.1-3.4%; P = 0.24] with breastfeeding. Nine-month cumulative mortality was 3.3% (95% CI 1.6-6.9%) in the breastfeeding arm group and 5.7% (95% CI 3.6-9.21%) for the formula feeding group (P = 0.20). HIV-free survival by 9 months was 95% (95% CI 91-970%) in the breastfeeding group and 94% (95% Cl 91-96%) for the formula feeding group (P = 0.66), with no significant difference in the adjusted analysis (adjusted hazard ratio for breastfeeding: 1.2 (95% CI 0.5-2.9%). Conclusion: Maternal HAART while breastfeeding could be a promising alternative strategy in resource-limited countries. (C) 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins
