The Maternal EED Study
Small Intestinal Microbiota of Low Body Mass Index (BMI) & Normal BMI Women of Reproductive Age and Microbiota-directed Balanced Energy Protein (MD-BEP) Supplementation in Maternal Environmental Enteric Dysfunction (EED)

Summary
Undernutrition among women of reproductive age is more common in South Asia than in any other region. In South Asia, the prevalence of maternal undernutrition varies between 10 and 40%. There is a scarcity of data on the contribution of small intestinal (SI) microbiota to pathogenesis of Environmental Enteric Dysfunction (EED) of malnutrition, as it is difficult to obtain gut biopsy specimens from malnourished individuals, especially children. The Bangladesh Environmental Enteric Dysfunction (BEED) study, involving participants who live in an urban slum (Mirpur) in Dhaka, provided an opportunity to examine the role of the duodenal microbiota in the pathogenesis of EED in children and also performed esophagogastroduodenoscopy (EGD) on thirty-eight 18-45-year-old malnourished (BMI\<18.5 kg/m2) women residing in the same resource-poor setting of Mirpur, Dhaka who failed to respond to an egg/milk/micronutrients- based nutritional intervention comparable to that given to children. In this intervention component, beginning at the end of the first trimester, low-BMI (\<18.5 kg/m2) pregnant women (aged 18-35 years) will be randomly assigned to receive either Microbiota-directed Balanced Energy Protein (MD-BEP) or Ready-to-Use-Supplementary Food Balanced Energy Protein (RUSF-BEP) for the duration of their pregnancy and during the first 3 postnatal months, in addition to standard antenatal care. A parallel cohort of age-matched normal-BMI pregnant women who will not receive any nutritional intervention will serve as a reference control group.

Interventions
Prototypes for nutritional interventions that are composed of locally available, affordable, culturally acceptable complementary foods commonly consumed in Bangladesh have recently been developed.
RUSF-BEP is composed of rice, lentil, sugar, soybean oil, and skimmed milk powder mixed with vitamin-mineral premix. MD-BEP is composed of chickpea flour, peanut flour, soy flour, green banana pulp, sugar, soybean oil, and vitamin-mineral premix. The results from previous studies support the notion that repair of impaired gut microbial community development could represent a new therapeutic concept for restoring healthy growth. RUSF-BEP will be given to one arm of low-BMI women of reproductive age and low-BMI pregnant women.
Aim 1A consists of performing EGD to women with low-BMI and normal BMI women with function dyspepsia. In order to enroll 30 participants with normal duodenal mucosal histology, we are planning to perform EGD on 100 healthy women (BMI 20-24.9 kg/m2) of childbearing age who have been referred for evaluation of functional dyspepsia. Undernourished low-BMI (\<18.5kg/m2; 18-35 years) women of childbearing age will be enrolled from Bauniabadh and adjacent slum area of Mirpur, Dhaka and EGD will be performed among 60 women. A total of 6-8 biopsy samples from SI and a dry duodenal aspirate will be collected for biopsy, histochemical and immunocytochemical analysis.
Normal BMI pregnant women will be counseled and followed up as per standard guidelines and will be provided routine antenatal care.
