Trial summary

Environmental Enteropathy (EE) is an acquired sub-clinical inflammatory gut condition in which alterations in intestinal structure, function, and local and systemic immune activation lead to impaired vaccine responses, decreased cognitive potential and undernutrition in low-middle income countries.

About this study

Environmental Enteropathy (EE) is an acquired sub-clinical inflammatory gut condition in which alterations in intestinal structure, function, and local and systemic immune activation lead to impaired vaccine responses, decreased cognitive potential and undernutrition in low-middle income countries. Approximately half of all global deaths in children aged less than five years are attributable to undernutrition making the study of EE an area of critical priority. However, given the operational limitations and ethical considerations for safely obtaining intestinal biopsies from young children in low resource settings, there have been few detailed investigations of human intestinal tissue in this vulnerable patient group for whom reversal of EE would provide the greatest benefit. EE biomarkers have been studied in different settings but these have not been correlated with the gold standard histopathology confirmation. The Study of Environment Enteropathy and Malnutrition in Pakistan (SEEM Pakistan) is designed to better understand the pathophysiology, predictors, biomarkers, and potential management strategies of EE to inform strategies to eradicate this debilitating pathology.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nutritional educationOther

    Also called Education

    4 week home delivered educational program that will focus on breast feeding and complimentary feeding. If child remains WHZ < -2 at by 9 months of age families will be shown 10 minute educational video detailing best practices for complimentary feeding.

  • Ready to Use Therapeutic FoodDietary supplement

    Also called RUTF

    If child remains WHZ < -2 despite nutritional education then will be managed according to Pakistan's Community Management of Acute Malnutrition protocol. This will include provision of ready to use therapeutic food (RUTF) to the child at home with close follow up. Utilization of the RUTF will be monitored closely by bi-weekly home visits.

  • Upper gastrointestinal endoscopy with biopsyProcedure or surgery

    Also called UGI endoscopy, Biopsy, Esophagoduodenoscopy

    If child remains at WHZ < -2 despite educational and dietary interventions, then will undergo medical evaluation for assessment of need for more advanced workup of malnutrition, including UGI endoscopy at AKUH. Results of the advanced work up, including the UGI endoscopy, will guide future management of these children.

Study groups in NCT03588013
Study groupRoleWhat they receive
Moderate/severe malnourishmentExperimentalPakistani children from age 0 to 6 months with weight for height Z score (WHZ) < -2 at the time of enrollment. Parents/caregivers of all participants will undergo a series of rehabilitative interventions to improve the child's nutrition and growth. Those participants who remain WHZ < -2 despite interventions are eligible for medical evaluation for more advanced workup of malnutrition, including UGI endoscopy and biopsy.
Receives: Other: Nutritional education; Dietary Supplement: Ready to Use Therapeutic Food; Procedure: Upper gastrointestinal endoscopy with biopsy
Well nourished childrenActive comparatorPakistani children from age 0 to 6 months who would be growing normally, with WHZ > 0, to serve as controls. Parents/caregivers of all participants will undergo a series of rehabilitative interventions to improve the child's nutrition and growth.
Receives: Other: Nutritional education
US children with celiac diseaseNo interventionComparative group for the Pakistani WHZ <-2 children who undergo UGI endoscopy and biopsy. Environmental Enteropathy and celiac disease have some shared features therefore we plan to enroll children under the age of 6 years with newly diagnosed celiac disease per endoscopy at CCHMC to assess the extent to which gene signatures and associated biologic pathways for children with celiac disease or environmental enteropathy overlap or differ.
US children with Crohn's diseaseNo interventionComparative group for the Pakistani WHZ <-2 children who undergo UGI endoscopy and biopsy. As some differentially expressed ileal gene signatures for Crohn's disease bear remarkable similarities to individual gene expression patterns previously reported for EE, children under the age of 10 years with newly diagnosed Crohn's disease per endoscopy at CCHMC will be enrolled to study these similarities and any differences
Healthy age-matched US childrenNo interventionComparative group for the Pakistani WHZ <-2 children who undergo UGI endoscopy and biopsy. Number of upper gastrointestinal endoscopies performed in children less than 2 years old are limited in Pakistan, therefore US age-matched controls will be used; healthy children < 3 years old will be enrolled, who will undergo endoscopy at CCHMC as part of a diagnostic workup for digestive symptoms, but whose biopsies and diagnoses are not supportive of eosinophilic esophagitis, celiac disease, or inflammatory bowel disease, and who were not treated with antibiotics ≤ 4 weeks prior to endoscopy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nutritional status in children assessed by measuring parameters of growth at 3-6 months of age

    Our birth cohort will be assessed for nutritional status by measuring parameters of growth, length, weight and height. These measurements will be calculated as Z scores according to WHO tables and children will be divided into the appropriate categories: Stunting as Length for Age Z-score < -2 SD (standard deviation), underweight as Weight-for-Age Z-score < -2 SD and wasting as Weight-for-Length Z-score < -2 SD, or normal-for-age.

    Measured: Approximately 3-6 months after entry into study

  2. Nutritional status in children assessed by measuring parameters of growth at 9 months of age

    Our birth cohort will be assessed for nutritional status by measuring parameters of growth, length, weight and height. These measurements will be calculated as Z scores according to WHO tables and children will be divided into the appropriate categories: Stunting as Length for Age Z-score < -2 SD (standard deviation), underweight as Weight-for-Age Z-score < -2 SD and wasting as Weight-for-Length Z-score < -2 SD, or normal-for-age.

    Measured: At approximately 9 months after entry into study

  3. Association of biomarkers with Environmental Enteropathy at 3-6 months of age

    Serum, stool, and urine biomarkers of EE will be collected and tested in malnourished and well-nourished children

    Measured: Approximately 3-6 months after entry into study

  4. Association of biomarkers with Environmental Enteropathy at 9 months of age

    Serum, stool, and urine biomarkers of EE will be collected and tested in malnourished and well-nourished children

    Measured: At approximately 9 months after entry into study

  5. Association of biomarkers with Environmental Enteropathy at the time of endoscopy and biopsy

    Serum, stool, and urine biomarkers of EE will be collected and tested in those children who are eligible to undergo upper GI endoscopy and biopsy

    Measured: At approximately 15 months after entry into study

  6. The use of UGI biopsy tissue for histopathological and multiomic workup for validation of biomarkers associated with EE

    Biopsy specimens from UGI endoscopy obtained from eligible children will be used for detailed histopathologic and multiomic work up to study the pathophysiology of EE, validate current biomarkers, and generate novel biomarker candidates

    Measured: At approximately 15 months after entry into study
