Gluten-induced mucosal changes in subjects without overt small-bowel disease
Lancet (London, England)
|March 7, 1981
Summary
Excessive gluten intake can trigger jejunal mucosal changes, even in individuals without overt celiac disease. This study highlights gluten
Area of Science:
- Gastroenterology
- Immunology
- Nutrition
Background:
- Celiac disease is an autoimmune disorder triggered by gluten.
- Susceptibility to gluten-induced changes may extend beyond diagnosed celiac patients.
Purpose of the Study:
- To investigate the effects of a high-gluten diet on jejunal mucosa in individuals with varying gluten sensitivity.
- To assess mucosal architecture, intraepithelial lymphocytes, and xylose absorption.
Main Methods:
- A six-week high-gluten diet (40g/day) was administered to normal volunteers, relatives of celiac patients, and patients with altered immunity.
- Jejunal mucosal biopsies were analyzed for architectural changes and intraepithelial lymphocyte counts.
- Xylose absorption tests were performed before and after the gluten challenge.
Main Results:
- Significant jejunal mucosal architectural changes, including villous atrophy, were observed in relatives and patients with altered immunity.
- Increased intraepithelial lymphocytes were noted in relatives and normal volunteers.
- Reduced xylose absorption occurred in relatives and normal volunteers.
- Diarrhea was reported in some participants, resolving upon diet normalization.
Conclusions:
- Excessive gluten consumption can induce significant jejunal mucosal alterations in susceptible individuals, including those without diagnosed celiac disease.
- These findings suggest a broader spectrum of gluten sensitivity than previously recognized.
- Further research is warranted to understand the mechanisms and long-term implications.
