Background and study aimsChronic infection caused by Helicobacter pylori (H. pylori) is associated with chronic gastritis, peptic ulcer disease, and gastric cancer. Eradication of H. pylori reduces morbidity of chronic gastritis and incidence of gastric cancer in high-risk population. We aimed at testing the efficacy of clarithromycin-based triple therapy and bismuth-based quadruple therapy for eradicating H. pylori in patients with chronic gastritis in Kuwait.Patients and methodsA total of 218 dyspeptic patients from different countries who were proved to have chronic gastritis by endoscopy and gastric biopsy were enroled. All of them were naïve to H. pylori eradication therapy. They were randomised into two groups: group A, received triple therapy (omeprazole, amoxicillin, and clarithromycin) for 10days; and group B, received quadruple therapy (omeprazole, bismuth subcitrate potassium, tetracycline, and metronidazole) for 10days. All patients were tested for eradication of H. pylori by carbon-13 urea breath test 4weeks after treatment.ResultsTotal response rate of eradication therapy in both groups was 77.5% (n=169). However, group B (n=100) had a higher eradication rate (88%) than group A (n=118) (68.6%). H. pylori eradication rate was significantly higher in males (84.2%) than females (70.2%) in both groups (p<0.01). There were no differences in eradication rates with regard to median age or nationality.ConclusionBismuth-based quadruple therapy is more effective as a first-line therapy than clarithromycin-based triple therapy for eradicating H. pylori in patients with H. pylori-related chronic gastritis in Kuwait.
