study on the efficacy and safety of berberine, minocycline, esomeprazole, and colloidal bismuth quadruple therapy in the initial treatment of helicobacter pylori.

Conditions: Helicobacter Pylori Infection; Chronic Gastritis

Summary: the aim of this study is to evaluate the efficacy and safety of a quadruple therapy consisting of berberine hydrochloride, minocycline, esomeprazole, and colloidal bismuth tartrate for the first phase eradication of helicobacter pylori. assuming that the quadruple therapy of berberine hydrochloride, minocycline, esomeprazole, and colloidal bismuth tartrate is no less effective than the bismuth containing quadruple therapy of amoxicillin and clarithromycin. patients diagnosed with helicobacter pylori infection will be randomly assigned to one of the aforementioned treatments. during the 6-week follow-up, urea breath test, rapid urease test, or helicobacter pylori fecal antigen test will be performed to confirm eradication. the aim of this study is to evaluate the efficacy and safety of a quadruple therapy consisting of berberine hydrochloride, minocycline, esomeprazole, and colloidal bismuth tartrate for the first phase eradication of helicobacter pylori. assuming that the quadruple therapy of berberine hydrochloride, minocycline, esomeprazole, and colloidal bismuth tartrate is no less effective than the bismuth containing quadruple therapy of amoxicillin and clarithromycin. patients diagnosed with helicobacter pylori infection will be randomly assigned to one of the aforementioned treatments. during the 6-week follow-up, urea breath test, rapid urease test, or helicobacter pylori fecal antigen test will be performed to confirm eradication.

screening: this phase will last a maximum of 14 days and subjects eligibility will be evaluated after signing informed consent. one of urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed in addition to the baseline routine evaluations. treatment: subjects are randomly assigned to treatment and will be treated for 14 days. a randomization visit will take place on day 0 and an end-of-treatment visit will take place between day 13 and 17. follow-up: includes one visits. approximately 28 days after the end of treatment. eradication of h. pylori will be confirmed by one of urea breath test，rapid urease test or helicobacter pylori stool antigen test.
