Brief Summary

The aim of this study was to evaluate the effect of gut microbiota after high-dose dual therapy combined with probiotics for Helicobacter pylori eradication

Detailed Description

The combination of vonoprazan (VPZ) and amoxicillin (VA therapy) has been shown to achieve notable eradication rates for Helicobacter pylori (H. pylori). Patients who receive this treatment are prone to adverse reactions, such as diarrhea, abdominal distention. We plan to combine probiotic therapy with the above treatment. However, it is not clear what changes in gut microbiota and metabolism may result from this therapy.
