Daily consumption of ready-to-use peanut-based therapeutic food increased fat free mass, improved anemic status but has no impact on the zinc status of people living with HIV/AIDS: a randomized controlled trial.


ABSTRACT: BACKGROUND:Food insecurity in sub-Saharan Africa and malnutrition constitute the main obstacles for successful treatment of people living with HIV/AIDS (PLWH). The aim of this study was to assess the effect of consuming daily 100 g RUTF (ready-to-use therapeutic food) as supplement, on body composition, anemia and zinc status of hospitalized PLWH in Senegal. METHODS:A Controlled clinical trial was conducted in 65 PLWH randomly allocated to receive either standard hospital diet alone (Control group: n = 33), or the standard diet supplemented with 100 g RUTF/day (RUTF group: n = 32). Supplementation was continued at home during 9 weeks. Individual dietary intakes were measured and compared to the Recommended Dietary Allowances. Body composition was determined using Bio-Impedance Analysis. Hemoglobin was measured by HemoCue and plasma zinc (PZ) concentration by atomic absorption spectrometry. PZ was adjusted to infection (CRP and ?1-AGP). All measures were conducted on admission, discharge and after 9 weeks home-based follow up. RESULTS:34 and 24% of the patients in RUTF and Control groups were suffering from severe malnutrition (BMI < 16 kg/m(2)), respectively. In both groups, more than 90% were anemic and zinc deficiency affected over 50% of the patients. Food consumed by the Control group represented 75, 14 and 55% of their daily recommended intake (DRI) of energy, iron and zinc, respectively. When 100 g of RUTF was consumed with the standard diet, the DRI of energy and zinc were 100% covered (2147 kcal, 10.4 mg, respectively), but not iron (2.9 mg). After 9 weeks of supplementation, body weight, and fat-free mass increased significantly by +11% (p = 0.033), and +11.8% (p = 0.033) in the RUTF group, but not in the Control group, while percentage body fat was comparable between groups (p = 0.888). In the RUTF group, fat free mass gain is higher in the patients on ART (+11.7%, n = 14; p = 0.0001) than in those without ART (+6.2%, n = 6; p = 0.032). Anemia decreased significantly with the supplementation, but zinc status, measured using plasma zinc concentration, remained unchanged. CONCLUSION:Improving PLWH' diet with 100 g RUTF for a long period has a positive impact on muscle mass and anemia but not on the zinc status of the patients.
