Clinical evaluation of four one-week triple therapy regimens in eradicating Helicobacter pylori infection

摘要

AIM: To evaluate clinical efficacy of four one-week triple therapies in eradicating Helicobacter pylori infection. METHODS: In this clinical trial, 132 patients with duodenal ulcer and chronic gastritis were randomly divided into four groups, and received treatment with OAC (omeprazole 20 mg + amoxicillin 1 000 mg + clarithromycin 250 mg), OFC (omeprazole 20 mg + furazolidone 100 mg + clarithromycin 250 mg), OFA (omeprazole 20 mg + furazolidone 100 mg + amoxicillin 1 000 mg) and OMC (omeprazole 20 mg + metronidazole 200 mg + clarithromycin 250 mg), respectively. Each drug was taken twice daily for one week. The ~(13)C urea breath test was carried out 4-8 weeks after treatment to determine the success of H pylori eradication. RESULTS: A total of 127 patients completed the treatment. The eradication rate for H pylori infection was 90.3%, 90.9%, 70.9% and 65.6%, respectively in OAC, OFC OMC and OFA groups. CONCLUSION: A high eradication rate can be achieved with one-week OAC or OFC triple therapy. Thus, one-week triple therapies with OAC and OFC are recommended for Chinese patients with duodenal ulcers and chronic gastritis.
