Abstract

Campylobacter pylori may cause gastritis and has been proposed as an etiologic factor in the development of peptic ulcer. However, it may be an acidsensitive microbe and before it can be implicated in the pathogenesis of peptic ulcer, it should be consistently found in ulcer patients with normal acid secretion. Thirty-six patients with C. pylori by Warthin-Starry stain underwent gastric analysis; 25 were normochlorhydric and 11 hypochlorhydric. Ulcers were present in 19 normochlorhydric patients (10, gastric; 9, duodenal) and 2 hypochlorhydric patients (gastric). Median basal acid output was higher for those with duodenal ulcer (38 mmol/h) than gastric ulcer (28 mmol/h) or miscellaneous endoscopic features (33 mmol/h). The hypergastrinemia seen in 12 patients with negative secretin provocation tests was believed to be due to various nongastrinoma conditions. Campylobacter pylori was found in 6 normogastrinemic patients with elevated acid output and in 1 gastrinoma patient with marked acid hypersecretion. Histologic chronic gastritis was present in all subjects and 29 had active chronic gastritis. Twenty-three patients were taking H2-receptor antagonists at the time of diagnosis which did not seem to interfere with culture results. Using standard acid secretory tests, we conclude that C. pylori can survive in a wide range of acid conditions.
