Aim : To investigate a repeat treatment regimen with the same antibiotic combination of amoxycillin and metronidazole in patients with continuing Helicobacter pylori infection. Methods : Eighty‐two patients with severe peptic ulcer disease and concurrent Helicobacter pylori infection were treated with a two week regimen of omeprazole (40 mg once daily), amoxycillin (750 mg t.d.s.) and metronidazole (400 mg t.d.s.). Upper gastrointestinal tract endoscopy was performed before, and approximately 2 months after, completion of antibiotic therapy. Biopsies were taken for rapid urease testing and the histological demonstration of H. pylori infection. Patients with persistent H. pylori infection at follow‐up endoscopy were re‐treated with a second and identical antibiotic treatment course. A subsequent endoscopic examination with accompanying biopsies was performed at least 6 weeks after the second treatment course and after a further 6, 18 and 30 months. Results : Eradication of H. pylori was achieved in 69 patients (84%, 95% CI: 75–90%) after the first treatment. Four patients (4/82=5%) were withdrawn from the study because of side‐effects. All of the remaining nine patients had their H. pylori infection eradicated after the second treatment course (95% CI: 70–100%). Seventy‐eight patients had a follow‐up examination after a median 30 months of the initial eradication of H. pylori , and all but one remained free of infection and none had an ulcer relapse. Conclusions : This study demonstrates that patients with persistent H. pylori infection after completing a primary course of omeprazole (40 mg once daily), amoxycillin (750 mg t.d.s.) and metronidazole (400 mg t.d.s.) will probably respond to a repeat course of treatment with the same antibiotic combination.
