About this study
Official title: Comparing the Efficacy and Impact on Gastrointestinal Microbiota of Reverse Hybrid Therapy and Concomitant Therapy in Helicobacter Pylori Eradication
Reverse hybrid therapy achieves a higher eradication rate than concomitant therapy remains unanswered.
Read the detailed description
A 14-day hybrid therapy invented by our study group appears very promising in H. pylori eradication, achieving excellent eradication rates of 99% and 97% according to per-protocol and intention-to-treat analyses, respectively. Recently, the investigators demonstrated that the eradication rate of reverse hybrid therapy was higher than that of standard triple therapy. However, whether reverse hybrid therapy achieves a higher eradication rate than concomitant therapy remains unanswered.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants in Which H. Pylori Was Eradicated
To assess eradication efficacy,repeated endoscopy with rapid urease test, histological examination and culture or Urea breath test.
Measured: sixth week after the end of anti- H. pylori therapy
