Helicobacter pylori in normal gastric mucosa.

ABSTRACT

Since the discovery of Helicobacter pylori (H. pylori) in 1983 several studies have established relationship of H. pylori with gastritis, duodenal ulcer disease and gastric carcinoma. H. pylori infection is widely prevalent and exposure occurs at younger age in our country. Several Western studies have shown prevalence of H. pylori in normal gastric mucosa to range from 0-25%. As similar information is not available from our country we estimated the prevalence of H. pylori in histologically normal gastric mucosa. Of the 50 asymptomatic volunteers studied, 33 showed histological evidence of gastritis and 28 of these were H. pylori. We conclude that histological gastritis is very common in young asymptomatic Indians and H. pylori infection is noticed in almost 25% subjects with histologically normal gastric mucosa.
