Interaction between Helicobacter pylori infection and untreated coeliac disease on gastric histological pattern.

Abstract OBJECTIVE: Helicobacter pylori infection is the major agent of gastric damage. Coeliac disease may affect the morphology and function of the entire gastrointestinal tract from the stomach to the colon. The aim of this study was to assess the gastric histological pattern in patients with H. pylori and untreated coeliac disease. MATERIAL AND METHODS: We retrospectively enrolled 183 H. pylori-positive patients with (85, group A) and without (98, group B) untreated coeliac disease. The groups were similar for age, gender and smoking habit, and all the patients came from the same geographical area. Histological evaluation of gastric pattern was performed on 4 biopsies (2 in the antrum, 2 in the corpus). Gastric damage was classified according to the modified Sydney System. Diagnosis of H. pylori infection was based on positivity to histology. The chi-square test was used to assess differences between groups. A p-value
