Prevalence of esophagitis in H. pylori-positive peptic ulcer disease and the impact of eradication therapy.
OBJECTIVE
There have been recent reports of reflux esophagitis apparently occurring de novo after cure of H. pylori in peptic ulcer disease. The possibility that this phenomenon might be explained, at least in part, by unmasking of coexistent disease has not been assessed. The aim of this study was to assess the prevalence of esophagitis in H. pylori-positive peptic ulcer disease and examine the short-term impact of H. pylori therapy on the esophagus.


METHODS
Esophagitis was systematically graded and the presence of hiatal hernia was noted in 244 peptic ulcer patients (duodenal 223; gastric 21) before and at least four weeks after triple therapy. H. pylori status was assessed using CLO test and histology, and esophagitis grade was assigned without knowledge of H. pylori status.


RESULTS
Of the 244 patients, 49 (20%) had esophagitis which was grade 2 or more in over two-thirds. The prevalence of esophagitis was similar in duodenal and gastric ulcer patients. The presence of hiatal hernia was strongly associated with the finding of esophagitis (P < 0.001). Of 241 patients evaluable after therapy, 215 (89%) were H. pylori-negative and 26 remained H. pylori-positive. Esophagitis tended to improve or remain stable after H. pylori therapy and worsened in only 2 of the 49 patients (4%). Of 192 patients with a normal esophagus at baseline endoscopy, 14 (7%) showed evidence of esophagitis after therapy. The presence of hiatal hernia, but not cure of H. pylori, was significantly associated with the development of esophagitis.


CONCLUSIONS
Our results indicate that esophagitis can coexist with peptic ulcer disease and persists after cure of H. pylori. Development of de novo esophagitis seems uncommon in the short-term after H. pylori therapy. Esophagitis in peptic ulcer disease is strongly associated with the presence of hiatal hernia.
