    Abstract:
    Little is known about the relationship between H. pylori infection and reflux esophagitis. To evaluate whether or not H. pylori plays a protective role in the pathogenesis of reflux esophagitis, the prevalence rates of reflux esophagitis depending on H. pylori status in consecutively diagnosed duodenal ulcer or benign gastric ulcer patients were evaluated. In addition, the incidence rates of reflux esophagitis depending on H. pylori status were evaluated for those patients who received follow-up endoscopy at least 6 months after eradication treatment. The prevalence rates of reflux esophagitis were 8.0% (2 patients) in the 25 H. pylori-negative duodenal ulcer group patients and 6.5% (36 patients) in the 555 H. pylori-positive duodenal ulcer group patients, and there was no statistical difference. Similarly, that of gastric ulcer patients was 9.4% (32 patients) in the 340 H. pylori-positive group patients, slightly higher than that in the 41 H. pylori-negative group patients 4.9% (2 patients), but without statistical significance. After eradication treatment the reflux esophagitis incidence rates were 2.5% (2 patients) in the 81 H. pylori-eradicated duodenal ulcer group patients and 7.7% (3 patients) in the 39 noneradicated duodenal ulcer group patients, and there was no statistical difference. Similarly, those of gastric ulcer patients were 6.8% (3 patients) in the 44 H. pylori-eradicated and 8.7% (2 patients) in the 23 noneradicated group patients again without statistical difference. These results suggest that H. pylori does not play a protective role in the pathogenesis of reflux esophagitis in patients with duodenal or gastric ulcer in Korea.
