First new analysis in three decades identifies which treatments for the long-term effects of malnutrition could help reduce mortality and poor health outcomes for children




QUEEN MARY UNIVERSITY OF LONDON





A comparison of treatments for malnutrition enteropathy, caused by severe acute malnutrition (SAM), has found evidence supporting the use of treatments to enhance the healing of mucosal membranes and reduce inflammation in the gut to improve the outcomes of children affected by long-team health consequences of a period of malnutrition. 

The Therapeutic Approaches to Malnutrition Enteropathy (TAME), led by researchers from Queen Mary University of London, evaluated four interventions for malnutrition enteropathy in a multi-centre phase II multi-arm trial in Zambia and Zimbabwe. No interventions for malnutrition enteropathy are currently available. The research gathered the first evidence in three decades which confirmed that treating malnutrition enteropathy can reduce intestinal damage amongst children experiencing the effects of complicated SAM.  

The study of 125 children who had been hospitalised due to complications arising from SAM found a biologically plausible new treatment paradigm, where intestinal damage drives systemic inflammation, contributing to stunting and developmental impairment, and increasing mortality. Researchers identified that a short course of treatment to restore mucosal integrity in the gut, can ameliorate underlying pathogenic pathways when added to standard care. 

Researchers found that GLP-2 agonists such as Teduglutide enhances mucosal healing in children with SAM. None of the other interventions studied showed any significantly differences compared to standard care, however budesonide was also shown to reduce the systemic inflammatory marker C-reactive protein (CRP), which is a predictor of infant mortality. Bovine colostrum and N-acetyl glucosamine also reduced inflammation; in addition, colostrum increased mucosal regeneration and N- acetyl glucosamine reduced diarrhoea. Further clinical trials are needed, but the TAME trial demonstrates that both treatments are likely to be safe, and confirms mucosal healing as a promising strategy in severe malnutrition. 

Paul Kelly, Professor of Tropical Gastroenterology at Queen Mary University of London, said: ‘Severe Acute Malnutrition (SAM) carries unacceptable mortality, particularly if accompanied by infection or medical complications, including enteropathy. We have shown that a short course of therapy added to standard care, aimed at restoring mucosal integrity, can reduce these complications, and we look forward to examining these treatments further in phase III clinical trials.’ 

Dr Jess Boname, Acting Head of Population and Systems Medicine at the Medical Research Council, said: “This study was funded by the Medical Research Council to address the tragedy that nearly half of deaths among children under five worldwide are linked to undernutrition. While the UK and many developing countries are suffering from an obesity crisis, undernutrition still causes a high death rate in children under five, mostly in low- and middle-income countries. We hope that this study will lead to effective treatments that will improve the health and wellbeing of children suffering from acute malnutrition and provide lasting benefits for the whole community.” 

Each year 17 million children, mostly in Africa, experience SAM, and malnutrition underlies almost half of all child deaths globally. Studies have confirmed the very high frequency of in resource poor countries and an association between such gut inflammation and mortality in complicated SAM.

About the Medical Research Council 

The Medical Research Council (MRC) is at the forefront of scientific discovery to improve human health. Founded in 1913 to tackle tuberculosis, the MRC now invests taxpayers’ money in some of the best medical research in the world across every area of health. Thirty-three MRC-funded researchers have won Nobel prizes in a wide range of disciplines, and MRC scientists have been behind such diverse discoveries as vitamins, the structure of DNA and the link between smoking and cancer, as well as achievements such as pioneering the use of randomised controlled trials, the invention of MRI scanning, and the development of a group of antibodies used in the making of some of the most successful drugs ever developed. Today, MRC-funded scientists tackle some of the greatest health problems facing humanity in the 21st century, from the rising tide of chronic diseases associated with ageing to the threats posed by rapidly mutating micro-organisms.
