Bangladesh Environmental Enteric Dysfunction (BEED) study: protocol for a community-based intervention study to...

Area of Science:

• Gastroenterology and Nutrition
• Pediatric Health
• Biomarker Discovery

Background:

• Environmental enteric dysfunction (EED) is a small intestinal condition linked to over 40% of stunting cases.
• Current diagnostic and treatment protocols for EED are not standardized.
• The Bangladesh Environmental Enteric Dysfunction (BEED) study addresses these gaps.

Purpose of the Study:

• To validate non-invasive biomarkers for EED against small intestinal biopsy.
• To elucidate the pathogenesis of EED.
• To identify potential therapeutic targets for EED and stunting interventions.

Main Methods:

• Community-based intervention recruiting stunted children, at-risk children, and malnourished adults.
• Collection of fecal, urine, and plasma samples to measure candidate EED biomarkers.
• Upper gastrointestinal endoscopy with biopsy for non-responders to nutritional therapy, followed by histopathological scoring and correlation with various health indicators.

Main Results:

• Biomarker validation against histopathological findings is ongoing.
• Correlation analysis between biomarkers, nutritional status, and microbial community structure is being performed.
• Data on pathogenesis and therapeutic targets are being generated.

Conclusions:

• The BEED study is establishing a framework for EED biomarker validation and pathogenesis research.
• Findings are expected to inform the development of novel diagnostic and therapeutic strategies for EED and stunting.
• This research has the potential to significantly impact child health outcomes in affected regions.
