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: (1) To evaluate the eradication efficacy of the mHDDT regimen and compare it with the bismuth-containing quadruple therapy (RBMT) in patients with H. pylori-infected gastroduodenal diseases; (2) To investigate the adverse effects and the level of treatment compliance among the patients.
Materials and Methods: A prospective comparative study 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 a 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.
