Abstract

Background & Aims: Antibiotic resistance is a major issue in anti-Helicobacter pylori treatment. This study was aimed at assessing the efficacy of 2 therapies in patients with resistant H pylori infection. Methods: Patients who had failed 1 or more eradication regimens underwent upper gastrointestinal endoscopy and 2 antral and 2 corpus biopsy specimens were taken for histology and culture. Metronidazole, clarithromycin, and amoxicillin resistance were determined by E-test. Patients were randomly assigned to 2 therapies: 1 group received pantoprazole 40 mg, amoxicillin 1 g, levofloxacin 250 mg, all twice daily for 10 days, and the other group was treated with omeprazole 20 mg twice daily for the first week and omeprazole 20 mg twice daily, tetracycline 250 mg 4 times daily, metronidazole 500 mg twice daily, and bismuth subcitrate 240 mg twice daily for the second week. Therapeutic success was evaluated by 13C urea breath test after 4 weeks of treatment. Results: We enrolled 44 patients in the levofloxacin-based regimen and 46 patients in the quadruple therapy. The former was successful in 31 of 44 (70%; 95% confidence interval: 53-87) and the latter in 17 of 46 (37%; 95% confidence interval: 23-47) patients, using intention-to-treat (ITT) analysis (P
