Helicobacter pylori and chronic antral gastritis in elderly patients

Fifty-five elderly patients with chronic antral gastritis (CAG) were studied to assess the relationship between Helicobacter pylori (H. pylori) status and CAG subtypes as specified in the Sydney System for Gastritis Classification. Twenty-eight patients (51%) were H. pylori positive and 27 (49%) H. pylori negative. H. pylori-positive patients had a significantly greater association with features of severe active CAG (chronic inflammation and polymorph activity) than H. pylori-negative patients. No association was apparent between H. pylori and more advanced stages of CAG (atrophy and intestinal metaplasia) thought to carry pre-malignant potential. The recognized association between dyspeptic symptoms in elderly people and an H. pylori-positive gastritis was confirmed. Use of NSAIDs correlated with a predominantly H. pylori-negative gastritis which was relatively asymptomatic.
