Intestinal villous atrophy in chronic active hepatitis
Scandinavian Journal of Gastroenterology
|January 1, 1979
Summary
Three chronic active hepatitis (CAH) patients showed villous atrophy, linked to lower albumin and higher IgG. A genetic link to HLA-B8 suggests coeliac disease may play a role, prompting gluten-free diet trials.
Area of Science:
- Gastroenterology
- Hepatology
- Immunology
Background:
- Chronic active hepatitis (CAH) is an inflammatory liver disease.
- Intestinal mucosal abnormalities can occur in various systemic conditions.
- The association between CAH and coeliac disease is not fully understood.
Purpose of the Study:
- To investigate the prevalence of intestinal villous atrophy in patients with chronic active hepatitis (CAH).
- To explore potential links between intestinal mucosal changes, serum markers, and genetic factors in CAH.
- To evaluate the implications for dietary interventions in CAH.
Main Methods:
- Suction biopsies of the upper jejunum were performed on 16 patients with CAH.
- Serum albumin and IgG levels were measured.
- HLA-B8 typing was conducted for patients with villous atrophy.
Main Results:
- Three out of 16 CAH patients (19%) exhibited total or subtotal villous atrophy.
- Patients with villous atrophy had lower serum albumin and higher IgG levels compared to those without.
- All three patients with villous atrophy carried the HLA-B8 genetic marker.
Conclusions:
- Intestinal villous atrophy may be present in a subset of CAH patients.
- A genetic predisposition, possibly involving HLA-B8, may link CAH and coeliac disease.
- Gluten-free diet trials are warranted for CAH patients with intestinal villous atrophy.
