Hospitalization for severe malnutrition among HIV-infected children starting antiretroviral therapy.

OBJECTIVE: To describe early hospitalization for severe malnutrition in HIV-infected children initiating antiretroviral therapy (ART). DESIGN: Randomized trial of induction-maintenance and monitoring strategies in HIV-infected children. SETTING: Three tertiary hospitals in Uganda and one in Zimbabwe. PARTICIPANTS: 1207 HIV-infected children, median age 6 years (range, 3 months to 17 years). INTERVENTION: Abacavir, lamivudine and nevirapine or efavirenz were given; children in induction-maintenance arms also received zidovudine to week 36. Pre-ART inpatient/outpatient nutritional rehabilitation for children with baseline severe malnutrition. MAIN OUTCOME MEASURES: : Hospitalization for severe malnutrition and change in CD4 cell percentage by week 12 after ART. Mortality and change in weight-for-age Z-score (WAZ) by week 24 after ART. RESULTS: Thirty-nine of 1207 (3.2%) children were hospitalized for severe malnutrition (20 with oedema), median 28 days [interquartile range (IQR) 14, 36] after ART for marasmus and 26 days (IQR 14, 56) after ART for kwashiorkor. Hospitalized children had lower baseline and greater 24-week rise in WAZ than nonhospitalized children (P < 0.001). Twenty-nine of 39 (74%) children admitted for severe malnutrition had underlying infections. Of 220 children with advanced disease (baseline WAZ and CD4 cell Z-scores both <-3), 7.3% [95% confidence interval (CI) 3.8, 10.7] developed kwashiorkor and 3.6% (95% CI 1.2, 6.1) developed marasmus by week 12. CD4 cell percentage rise was similar among groups (P = 0.37). Twenty-four-week mortality was 32, 20 and 1.7% among children hospitalized with marasmus, kwashiorkor and not hospitalized, respectively, (P < 0.001). CONCLUSION: One in nine children with advanced HIV required early hospitalization for severe malnutrition after ART, with a 15-fold increase in 6-month mortality compared with nonhospitalized children. Integration of HIV/malnutrition services and further research to determine optimal ART timing, role of supplementary feeding and antimicrobial prophylaxis are urgently required.
