Egg-protein-induced villous atrophy
Journal of Pediatric Gastroenterology and Nutrition
|January 1, 1982
Summary
Egg protein causes damage to the small intestine in infants with intolerance. Ingestion led to villous atrophy and impaired nutrient absorption, confirming egg protein as a cause of infant flat mucosa.
Area of Science:
- Pediatric Gastroenterology
- Immunology
- Nutrition Science
Background:
- Investigating the impact of food protein intolerance in infants.
- Understanding the specific effects of egg protein on infant gastrointestinal health.
Observation:
- A 9-month-old infant with a known egg protein intolerance was studied.
- The infant ingested egg protein, and effects on the small bowel mucosa were monitored within 24 hours.
Findings:
- Marked villous atrophy of the small intestine was observed.
- Depletion of mucosal oligosaccharidases and impaired xylose absorption occurred.
- Depressed serum complement levels were also noted post-ingestion.
Implications:
- Egg protein is identified as a cause of 'flat mucosa' in infants.
- Highlights the significant gastrointestinal and immunological effects of food protein intolerance.
- Underscores the need for careful dietary management in infants with food sensitivities.
