Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Malnutrition is a major global public health issue, contributing to poor health and early morbidities in children under five, particularly in developing countries. In 2021, 5 million children died worldwide due to infectious diseases or malnutrition, with Pakistan having the highest under-five mortality rate. With a population of approximately 229 million, Pakistan is the fifth most populous country in the world. In Pakistan, under-five mortality is 63.3 per 1000 live births which has declined from 139.8 in 1990 to 63.3 in 2021 (WHO, 2022, UNICEF, 2023). The monsoon season's massive flooding in Pakistan has worsened the humanitarian situation, endangering the already vulnerable population. UNICEF reports high rates of acute malnutrition, political instability, economic decline, and coronavirus disease 2019 effects. However, there is limited evidence on the efficacy of probiotics for infants in Pakistan.

Metagenomics is the study of microorganisms' genomes, examining all microorganisms in an ecological site's genomes. It involves extracting and sequencing DNA using high-throughput techniques. Scientists can identify genes with significant features using computer analysis. The distal intestine contains around one trillion organisms per milliliter of luminal contents, and understanding their potential for energy and nutrient harvest is crucial in malnourished individuals.

Alpha diversity is the analysis of species diversity in a sample, measured by observed species index, Chao1 index, Shannon index, Simpson index, and good-coverage index. It is proportional to the first four values and indicates less undiscovered species. The distal intestine contains around one trillion organisms per milliliter of luminal contents, with an increased capacity for energy harvest in malnourished individuals.

The present study aims to measure the following objectives. i. -To estimate the microbiome degree of diversity among malnutrition children micro-biota defined by 16 Svedberg (S) ribosomal ribonucleic acid gene sequencing.

ii. -To evaluate the interpersonal differences in the structure and functioning of the gut microbiome that affect a person's vulnerability to malnutrition.

iii. -To determine how microbiomes are shaped by host genotypes, environmental exposures, including exposure to malnutrition in children mothers, and other family members, nutritional status, and lifestyles, including diet.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Metagenomics is the study of microorganisms' genomes through the direct extraction and cloning of their DNA from a collection of microorganisms, also known as environmental and community genomics. The examination of all the microorganisms in an ecological site's genomes, the majority of which cannot be produced under standard laboratory conditions, is called metagenomics. In order to achieve this, the site's microbial population must first be removed, and then its DNA must be isolated and sequenced using high-throughput techniques. Scientists may identify genes with significant features, such as virulence genes or genes encoding enzymes of commercial significance, using computer analysis of a sequence.

Around one trillion organisms per milliliter of luminal contents are found in the distal intestine, where the majority of these bacteria are found. It is essential to describe the microbiota and its microbiome in malnourished persons and to define their potential to harvest energy and nutrients in light of the discovery that the intestinal microbiota/ microbiome linked with obesity has an increased capacity for energy harvest.

Deficiency of iron has been recognized in malnourished children. Iron present in RUTF is not sufficient to elevate "circulating levels of ferritin into the optimal physiological range. Prebiotics has been proven to have anti-inflammatory and antimicrobial actions that might enhance response to standard therapy for severe acute malnutrition (SAM), Targeting the gut microbiota through the use of Prebiotics as part of treatment in malnourished children may present an affordable and cost-effective strategy in the prevention and also in the treatment Fortifying the microbiota with Prebiotics could enhance energy and may protect against diarrhoea. However, randomized controlled trials evaluating the effects of prebiotic supplementation in children with severe acute malnutrition have not previously been done. So clinical evidence is lacking and cannot be translated into clinical practice.

Content of "Ready-to-use therapeutic food" may not be optimal to support weight gain a in children with severe acute malnutrition. Further trials are required to conclude whether Prebiotics containing Galactooligosaccharides supplement can improve weight gain in children with severe acute malnutrition in other settings.
