Abstract

To investigate the frequency of Helicobacter pylori and gastritis in asymptomatic adults, 30 healthy volunteers underwent upper endoscopy. Biopsy specimens were obtained from the corporeal and antral mucosa of the stomach. The specimens were examined by light microscopy for gastritis and the occurrence of H. pylori. In 12 subjects signs of gastritis were noted at endoscopy, but only in 7 of them was this diagnosis confirmed histologically. No other abnormalities were observed by the endoscopist. Histologic examination was normal in 17 subjects, but in 13 subjects (43%) inflammation was found in the gastric specimens. Ten had inflammation both in the corpus and in the prepyloric specimens, and in six of these subjects H. pylori was discovered. H. pylori was only found in subjects with inflammation in both the corpus and the antrum. Subjects with gastritis were slightly older than subjects with normal gastric mucosa (median age, 47 versus 37 years; not significant). In the group of subjects with gastritis, persons with H. pylori were older than those without (median age, 53.5 versus 36 years; p = 0.05). The results of our study indicate that gastritis is present before colonization with H. pylori occurs. This could imply that H. pylori is not the cause of gastritis but that the presence of gastritis is a prerequisite for colonization of the bacterium in the stomach.
