Background: Intestinal metaplasia is a precancerous lesion. Helicobacter pylori is identified as an important cause of gastric cancer. This study is aimed at assessing the intestinal metaplasia and Helicobacter pylori infection and their relation in patients with chronic gastritis. Patients and methods: Study includes 75 patients with chronic gastritis diagnosed by clinical, endoscopic and histopathological criteria. Intestinal metaplasia is diagnosed by HE stain. Hp infection is tested by CLO-test from Viet A Ltd. Results: Hp infecton rate in this study is 66.67% and is highest in patients with antral gastritis. Intestinal metaplasia is found in 29.33% of patients with chronic gastritis with the predominance of complete intestinal metaplasia. The rate of intestinal metaplasia is the highest in the group with chronic atrophic gastritis. There is a significant relationship between intestinal metaplasia and Hp ìnfection. Conclusion: Hp and intestinal metaplasia are found at significant rates in chronic gastritis. The rate of intestinal metaplasia is clearly higher in the group with Hp-positive chronic gastritis.
