Perspective on alternative therapeutic feeds to treat severe acute malnutrition in children aged between 6 and 59 months in sub-Saharan Africa: a narrative review

Abstract

Abstract Worldwide, nearly 200 million children younger than 5 years old suffer from stunting and wasting, 2 different types of undernutrition. Moreover, 45% of deaths among children in that age group are associated with these conditions. Severe acute malnutrition (SAM) refers to children with a weight-for-height z score < −3, a midupper arm circumference < 115 mm, or the presence of bilateral edema, and is especially prevalent in low- and middle-income countries. Undernutrition in children can have a major impact on both their physical and cognitive development. It can lead to infections and death if it remains undetected or untreated. The use of therapeutic feeds is an important component in the management of SAM, which remains a challenge in poorly resourced countries. The aim of this review was to assess the alternatives to the standard therapeutic foods used to treat SAM and to summarize their advantages and disadvantages, providing an overview of current research. A literature search was performed from September to November 2022 using PubMed, the Trip medical database, and the German Institute for Medical Documentation and Information (DIMDI). This review includes 13 randomized controlled trials testing alternatives to the standard therapeutic foods used to treat SAM by using alternative ingredients or a reduced dosage. The results show that, while a few alternative ready-to-use therapeutic food formulas lead to recovery rates similar to those seen with the standard protocol, many alternatives were less effective in the affected children. Thus, the evidence is not yet strong enough to change the World Health Organization’s guidelines. The review identifies promising results of treatment alternatives related to treatment outcomes and costs. Additional research should focus on the interventions that positively impact the recovery process of severely malnourished children to facilitate the treatment and enable greater treatment coverage worldwide.
