Background: The judicious use of the world health organization (WHO) guidelines in the management of severe acute malnutrition (SAM) is very crucial in avoiding complications. We investigated the incidence of refeeding syndrome and its associated factors in children under 5 years with SAM receiving treatment as inpatients. Methods: A prospective study of 104 children with SAM admitted to the paediatric unit of Dr George Mukhari Academic Hospital (a teaching hospital in Pretoria, South Africa) since March 2014 to March 2015 was conducted. On admission, history on socioeconomic status and co-morbidities, a comprehensive clinical examination, and anthropometric measurements were obtained. All the patients were managed using the 10 steps of management of malnutrition with cautious feeding and broad spectrum antibiotics being instituted. Bloods were taken for calcium, magnesium, phosphorous, urea, and electrolytes on admission and compared to repeat bloods done on day 5 post admission.

The duration of pneumonia and of diarrhea is reported to be longer in HIV-infected than in uninfected children. We assessed the effect of a multi-micronutrient supplement on the duration of hospitalization in HIV-infected children. In a double-blind, randomized trial, HIV-infected children (4-24 mo) who were hospitalized with diarrhea or pneumonia were enrolled (n = 118) and given a daily dose of a multi-micronutrient supplement (containing vitamins A, B complex, C, D, E, and folic acid, as well as copper, iron, and zinc at levels based on recommended daily allowances) or a placebo until discharge from the hospital. Children's weights and heights were measured after enrollment and micronutrient concentrations were measured before discharge. On recovery from diarrhea or pneumonia, the children were discharged and the duration of hospitalization was noted. Anthropometric indices and micronutrient concentrations did not differ between children who received supplements and those who received placebos. Overall, the duration of hospitalization was shorter (P < 0.05) among children who were receiving supplements (7.3 +/- 3.9 d) (mean +/- SD) than in children who were receiving placebos (9.0 +/- 4.9); this was independent of admission diagnosis. In children admitted with diarrhea, the duration of hospitalization was 1.6 d (19%) shorter among children receiving supplements than in those receiving placebos, and hospitalization for pneumonia was 1.9 d (20%) shorter among children receiving supplements. Short-term multi-micronutrient supplementation significantly reduced the duration of pneumonia or diarrhea in HIV-infected children who were not yet receiving antiretroviral therapy and who remained alive during hospitalization.

Human immunodeficiency virus (HIV)-infected children generally show poor growth. Episodes of diarrhoea and pneumonia in HIV-infected children are thought to be more severe than in HIV-uninfected children. The objective of this study was to compare duration of hospitalization, appetite and nutritional status of HIV-infected children with that of uninfected children. A cross-sectional study was performed on children (2-24 months) admitted with diarrhoea or pneumonia to the university hospital. Children were tested for HIV, and the duration of hospitalization was noted for 189 children. Follow-up for blood analysis (n=154) and appetite measurement (n=48) was performed 4-8 weeks after discharge. Appetite was measured as ad libitum intake of a commercial infant cereal using highly standardized procedures. Hospitalization (in days) was significantly longer in HIV-infected children; among children admitted with diarrhoea (5.9 ± 1.9 vs. 3.8 ± 1.5) (mean ± standard deviation) and with pneumonia (9.0 ± 2.5 vs. 5.9 ± 1.9). Serum zinc, iron and transferrin concentrations, and haemoglobin levels were significantly lower in HIV-infected children compared with uninfected children. Appetites [amounts eaten (g) per kg body weight] of HIV-infected children were significantly poorer than those of HIV-uninfected children (18.6 ± 5.8 vs. 25.2 ± 7.4). The eating rates (g min(-1) ) of HIV-infected children were also slower (17.6 ± 6.2 vs. 10.1 ± 3.7) Mean Z-scores for length-for-age were significantly lower among HIV-infected children compared with HIV-uninfected children. Weight-for-length Z-scores were not significantly different. In summary, HIV-infected children had a 55% longer duration of hospitalization and a 21% lower appetite.
