    Outcomes of the South African National Antiretroviral Treatment Programme for children: The IeDEA Southern Africa collaboration
    (2009) Davies, M; Keiser, O; Technau, K; Eley, B; Rabie, H; Van Cutsem, G; Giddy, J; Wood, R; Boulle, A; Egger, M; Moultrie, H
    Objectives: To assess paediatric antiretroviral treatment (ART) outcomes and their associations from a collaborative cohort representing 20% of the South African national treatment programme. Design and setting: Multi-cohort study of 7 public sector paediatric ART programmes in Gauteng, Western Cape and KwaZulu-Natal provinces. Subjects: ART-naïve children (≤16 years) who commenced treatment with ≥3 antiretroviral drugs before March 2008. Outcome measures: Time to death or loss to follow-up were assessed using the Kaplan-Meier method. Associations between baseline characteristics and mortality were assessed with Cox-proportional hazards models stratified by site. Immune status, virologic suppression and growth were also described by duration on ART. Results: The median (IQR) age of 6078 children with 9368 child-years of follow-up was 43 (15 – 83) months, with 29% being <18 months. Most were severely ill at ART initiation. More than 75% of children were appropriately monitored at 6-monthly intervals with viral load suppression (<400 copies/ml) being 80% or above throughout 36 months of treatment. Mortality and retention in care at 3 years were 7.7% (95%CI: 7.0% – 8.6%) and 81.4% (80.1% - 82.6%) respectively. Together with young age, all markers of disease severity (low weight-for-age z-score; high viral load; severe immune suppression, stage 3/4 disease and anaemia) were independently associated with mortality. Conclusions: Dramatic clinical benefit for children accessing the national ART programme is demonstrated. Higher mortality in infants and those with advanced disease highlights the need for early diagnosis of HIV infection and commencement of ART.

    Role of micronutrients in HIV infection
    (2005) Hussey, G; Buys, H; Cowburn, C; Eley, B; Hendricks, M
    More than 60% of the estimated 40 million persons with HIV/AIDS worldwide live in sub-Saharan Africa, where poverty, social insecurity, food shortages and malnutrition are major problems.1 In children under the age of 5 years, who live in developing countries, malnutrition has been associated with 50% of the 10.8 million deaths mainly caused by neonatal disorders, diarrhoea, pneumonia, malaria and HIV/AIDS.2 Likewise micronutrient deficiencies are widespread and are associated with increased morbidity and mortality particularly in relation to infectious diseases.3 This review focuses on the interaction between micronutrients and HIV/AIDS and discusses recent research findings that may have important public health implications in terms of the case management of persons with HIV/AIDS.
