Transmission of human immunodeficiency virus type 1 (HIV-1) via breast-feeding can occur throughout lactation. Defining both fluctuation in breast-milk virus level over time and how breast-milk virus correlates with mother-to-child transmission is important for establishing effective interventions. We quantified breast-milk HIV-1 RNA levels in serial samples collected from 275 women for up to 2 years after delivery. Higher maternal plasma virus load, lower maternal CD4 T cell count, and detection of HIV-1 DNA in maternal genital secretions were significantly associated with elevated breast-milk HIV-1 RNA. Within women who breast-fed, median virus load in colostrum/early milk was significantly higher than that in mature breast milk collected 14 days after delivery (P< or =.004). Breast-feeding mothers who transmitted HIV-1 to their infants had both significantly higher breast-milk viral RNA throughout lactation and more-consistent viral shedding, compared with mothers who did not transmit HIV-1. In breast-feeding women, a 2-fold-increased risk of transmission was associated with every 10-fold increase in breast-milk virus load (95% confidence interval, 1.3-3.0; P<.001). These results indicate that the risk of infant infection from breast-feeding is influenced by breast-milk virus load, which is highest early after delivery.
OBJECTIVE: To assess the impact of a continuing medical education program based on the WHO's 10 steps to successful breast-feeding. STUDY DESIGN: An observational before-and-after study at a teaching hospital. Data for two random samples of 50 women before and 50 after the intervention were collected from medical records and completed by a mail questionnaire. RESULTS: Seventy-six percent of mothers initiated breast-feeding in the two samples. The median duration of breast-feeding was 12 weeks and did not differ between the before and after groups. The percentage of newborns separated from their mother more than 4h a night decreased substantially after the intervention (13% versus 52% before the intervention, P<0.01). In-hospital formula provision also decreased after the intervention (63% of newborns versus 82% before intervention, P=0.07). CONCLUSION: This pilot study has enabled authors to document the feasibility of evaluating the impact of continuing education of maternity ward staff.
