Helicobacter Pylori Eradication Clinical Trial
Official title:
Optimal Recheck Time for Helicobacter Pylori Eradication: A Prospective, Single-center, Open-label, Randomized Controlled Trial
Although Urea breath test has been commonly used to recheck the efficiency of Helicobacter pylori eradication, there has been no randomized trials comparing the accuracy of Urea breath test results at different times after eradication. The investigators aim to assess the accuracy and influence factors of post-therapy test at different times and follow up the cut off samples to optimize the best time to recheck.
The investigators plan to conduct a single-center, open-label, randomized controlled study in Zhejiang, China. Treatment-naive H. pylori-positive participants (n = 900) were randomly assigned to three groups in a 1:1:1 ratio with the same eradication regimen: amoxicillin 1000 mg, clarithromycin 500mg, rabeprazole 10mg, and colloidal bismuth 200 mg each given twice a day for 14 days. Urea breath tests were administered at different times after the treatment: 4 to 6 weeks, 6 to 8 weeks, and 8 to 10 weeks, respectively, for different groups. ;
