Probiotic For the Improvement of Environmental Enteropathy in Pregnant Women in Senegal

Stunting in young children refers to attenuated linear growth. In the year 2020, 149.2 million children under the age of 5 were stunted, accounting for 22% of stunting globally. Stunting has short- and long-term consequences of increased morbidity and mortality, impairment of neurocognitive development , impaired responses to oral vaccines, and increased risk of non-communicable diseases. Stunting is partly driven by Environmental Enteric Dysfunction (EED), an enteropathic condition characterised by altered gut permeability, infiltration of immune cells and changes in villous architecture and cell differentiation. EED may help explain why nutritional supplementation either during pregnancy or early childhood has minimal value in correcting childhood stunting. Probiotics may serve to overcome the problem of EED through all mechanisms of pathogenicity, by providing additional bacteria that may help in intestinal decolonization of pathogenic microorganisms (changing the microbiological niche), promoting epithelial healing, improving nutrient absorption, and restoration of an appropriate immune balance between tolerance and responsiveness. This trial will explore the conceptual framework, that a well known probiotic, that can improve the composition of the gut microbiota, can reduce biomarkers of intestinal inflammation and gut health. This will restore healthy microbial signalling to the host epithelium, ameliorate barrier function through secretion of mucus and antimicrobial factors, and improve nutrient availability.
