BACKGROUND: Helicobacter pylori eradication reduces the recurrence of duodenal ulcers. It is unclear why duodenal ulcers rarely recur in the absence of reinfection with H. pylori or NSAID treatment.
METHODS: Basal, gastrin-releasing peptide- and pentagastrin-stimulated peak acid outputs in patients with ulcer relapse after H. pylori eradication were measured, and compared with patients without ulcer relapse after H. pylori eradication.
RESULTS: Pentagastrin-stimulated peak acid output was significantly higher in H. pylori-positive patients with duodenal ulcers than in H. pylori-negative controls, and fell significantly after H. pylori eradication. In H. pylori-negative patients with recurrent duodenal ulcers, pentagastrin-stimulated peak acid output was significantly higher than in controls and similar to H. pylori-positive patients with duodenal ulcers.
CONCLUSIONS: These findings suggest that duodenal ulcer relapse after eradication of H. pylori may be related to high pentagastrin-stimulated peak acid output. In this subset of patients with duodenal ulcers, maintenance anti-secretory treatment may be necessary to prevent relapse.
