      Prevention of mother-to-child transmission (PMTCT) is essential in HIV/AIDS control. We analysed 2000-05 data from mother-infant pairs in our PMTCT programme in rural Uganda, examining programme utilization and outcomes, HIV transmission rates and predictors of death or loss to follow-up (LFU). Out of 19,017 women, 1,037 (5.5%) attending antenatal care services tested HIV positive. Of these, 517 (50%) enrolled in the PMTCT programme and gave birth to 567 infants. Before tracing, 303 (53%) mother-infant pairs were LFU. Reasons for dropout were infant death and lack of understanding of importance of follow-up. Risk of death or LFU was higher among infants with no or incomplete intrapartum prophylaxis (OR = 1.90, 95% CI 1.07-3.36) and of weaning age <6 months (OR 2.55, 95% CI 1.42-4.58), and lower in infants with diagnosed acute illness (OR 0.30, 95% CI 0.16-0.55). Mother-to-child HIV cumulative transmission rate was 8.3%, and 15.5% when HIV-related deaths were considered. Improved tracking of HIV-exposed infants is needed in PMTCT programmes where access to early infant diagnosis is still limited.

      Children living with HIV continue to be in urgent need of combined antiretroviral therapy (ART). Strategies to scale up and improve pediatric HIV care in resource-poor regions, especially in sub-Saharan Africa, require further research from these settings. We describe treatment outcomes in children treated in rural Uganda after 1 and 2 years of ART start.
    • Nutrition outcomes of HIV-infected malnourished adults treated with ready-to-use therapeutic food in sub-Saharan Africa: a longitudinal study.

      Among people living with HIV/AIDS, nutritional support is increasingly recognized as a critical part of the essential package of care, especially for patients in sub-Saharan Africa. The objectives of the study were to evaluate the outcomes of HIV-positive malnourished adults treated with ready-to-use therapeutic food and to identify factors associated with nutrition programme failure.
