Abstract
Background: Modified high-dose dual therapy (mHDDT), consisting of a proton pump inhibitor and amoxicillin, utilizes fewer drugs while maintaining efficacy for H. pylori eradication, particularly in regions with low amoxicillin resistance. Objectives: This study aimed to evaluate the eradication efficacy of mHDDT (rabeprazole-amoxicillin) compared to bismuth-containing quadruple therapy (RBMT) in patients with H. pylori-infected gastroduodenal diseases and to assess adverse effects, treatment adherence, clinical symptom improvement, and endoscopic outcomes. Materials and Methods: A randomized controlled trial was conducted at the University of Medicine and Pharmacy Hospital, Hue University, from April 2022 to August 2023. A total of 103 H. pylori-infected patients were randomly assigned to either the mHDDT group or the RBMT group. Results: Based on intention-to-treat analysis, the eradication rates were 80.0% for the mHDDT group and 81.1% for the RBMT group (p = 0.810). Per-protocol analysis showed rates of 81.6% and 86.0%, respectively (p = 0.555). Notably, the incidence of adverse events was significantly lower in the mHDDT group (30.6%) compared to the RBMT group (84.0%) (p < 0.001). Treatment adherence was higher in the mHDDT group (91.8% vs. 78.0%), although this difference did not reach statistical significance (p = 0.055). Conclusion: The mHDDT regimen is an simple treatment option, offering comparable efficacy to RBMT for H. pylori eradication and improvements in clinical symptoms and gastroduodenal mucosal healing with significantly fewer side effects.
