Abstract
BACKGROUND AND AIM: Risk factors for progression of gastric atrophy have not been fully elucidated. The aim of this study was to evaluate the risk factors for the development of atrophic gastritis in patients with Helicobacter pylori (H. pylori ) infection. METHODS: We reviewed 206 H. pylori-infected patients retrospectively. Endoscopic gastric atrophy was classified into closed- and open-type. We conducted univariate and multivariate logistic regression analyses on the contribution of age, sex, body mass index, past history of cancer, the first-degree family history of gastric cancer, habitual smoking and alcohol drinking, and endoscopic findings of gastric ulcer or duodenal ulcer for open-type gastric atrophy. RESULTS: On multivariate analysis, age (odds ratio = 1.079, 95% confidence interval = 1.048-1.11, p < 0.001), family history of gastric cancer (odds ratio = 3.967, 95% confidence interval = 1.414-10.6, p = 0.006) and duodenal ulcer (odds ratio = 0.834, 95% confidence interval = 0.711-0.977, p = 0.024) were the factors independently associated with open-type gastric atrophy. CONCLUSIONS: A first-degree family history of gastric cancer, absence of duodenal ulcer, and old age were independent risk factors for the progression of gastric atrophy among H. pylori-infected patients. Careful examination with upper gastrointestinal endoscopy is necessary in patients with such risk factors.
