PATIENTS: This randomised controlled clinical trial was conducted on 312 patients with H. pylori infection who had referred to the Taleghani Research Center of Gastroenterology and Liver Disease. METHODS: Patients were randomly divided into two groups. Group A patients (162 patients) received amoxicillin 1g and metronidazole 500 mg b.i.d., bismuth 240 mg b.i.d. and omeprazole 40 mg q.i.d. in two divided doses. Patients in group B (150 patients) received the same regimen plus 500 mg vitamin C per day. All patients received therapy for 2 weeks.
