Esomeprazole/Vonoprazan Combined With High-dose Amoxicillin Dual Therapy for Primary Eradication of Helicobacter Pylori Infection

Esomeprazole / Vonoprazan Combined With High-dose Amoxicillin Dual Therapy for Primary Eradication of Helicobacter Pylori Infection: a Multi-center, Prospective, Open-label, Randomized Controlled Clinical Trial

This study intends to collect the clinical data of patients with Helicobacter pylori infection, and to observe and count the high-dose double therapy and the traditional quadruple / triple therapy ( i.e., esomeprazole + amoxicillin double high-dose double therapy and esomeprazole + amoxicillin + clarithromycin + colloidal bismuth tartrate traditional quadruple therapy or Vonoprazan + amoxicillin double high-dose double therapy and Vonoprazan + amoxicillin + clarithromycin triple therapy ). The eradication rate of Helicobacter pylori was compared between the two different regimens respectively, and the efficacy, safety and compliance of different regimens were compared. It provides a new reference for clinical treatment of Helicobacter pylori, and has great clinical value and significance for simplifying the anti-Helicobacter-pylori treatment plan, increasing patient compliance, and exploring efficient anti-Helicobacter-pylori therapy suitable for the Chinese population.
