  1. Influence of infant-feeding patterns on early mother-to-child transmission of HIV-1 in Durban, South Africa.

    Article - En anglais

    The observation that mother-to-child transmission of HIV-1 can occur through breastfeeding has resulted in policies that recommend avoidance of breastfeeding by HIV-1-infected women in the developed world and under specific circumstances in developing countries.

    WE compared transmission rates in exclusively breastfed, mixed-fed and formula-fed (never breastfed) infants to assess whether the pattern of breastfeeding is a critical determinant of early mother-to-child transmission of HIV-1.

    Methods We prospectively assessed infant-feeding practices of 549 HIV-1 infected women who were part of a vitamin A intervention trial in Durban, South Africa.

    The proportions of HIV-infected infants at 3-months (estimated by use of Kaplan-Meier life tables) were compared in the three different feeding groups.

    HIV-infection was defined by a positive RNA-PCR test.

    Findings :

    At 3 months, 18.8% (95% Cl 12.6-24.9) of 156 never-breastfed children were estimated to be HIV-1 infected compared with 21.3% (17.2-25.5) of 393 breastfed childre (p=0.5).

    The estimated proportion (Kaplan-Meier) of infants HIV-1 infected by 3 mths was significantly lower for those exclusively breastfed to 3 mths than in those who received mixed feeding before 3 mths (14.6% [7.7-21.4] vs 24.1% [19.0-29.2], p=0.03).

    After adjustment for potential confounders (...) exclusive breastfeeding carried a significantly lower risk of HIV-1 transmission than mixed feeding (...) and a similar risk to no breastfeeding (...).
