ABSTRACT=Background: Currently, the management of Helicobacter pylori (H. pylori) infection in elderly patients is controversial. We investigated whether high-dose dual therapy would serve as the first-line therapy in elderly patients.
Methods: This was a single-center, randomized study of 150 elderly patients with H. pylori infection who were randomly assigned to 14-day therapy with pantoprazole 40 mg 3 times daily and either amoxicillin 1,000 mg 3 times daily or amoxicillin 1,000 mg twice daily, clarithromycin 500 mg twice daily and bismuth 220 mg twice daily. H. pylori eradication was evaluated by a 13C-urea breath test 4 weeks after the completion of treatment.
Results: Successful eradication was achieved in 89.3% of the high-dose dual therapy (HT) group in the intention‐to‐treat (ITT) analysis, 91.7% in the modified intention-to-treat (mITT) analysis, and 93.0% for per‐protocol (PP) analysis which was similar to the bismuth-containing quadruple therapy (BQT) group (86.6%, 87.8%, and 90.3%, respectively). There were no significant difference between the HT group and the BQT group in the ITT analysis (p = 0.484), mITT analysis (p = 0.458), or PP analysis (p = 0.403). HT was associated with fewer side effects (10.6% of patients) than BQT (26.6%) (p = 0.026).
Conclusion: In this trial, we found that 14-day HT had a similar eradication rate to BQT but fewer side effects, which may be better for elderly patients.
