Abstract: BACKGROUND AND AIM: Tegoprazan, a potassium-competitive acid blocker, can be used as a substitute for proton pump inhibitors in Helicobacter pylori eradication therapy; some studies have reported improved efficacy. In Korea, where clarithromycin resistance rates are high, we aimed to compare the efficacies of tegoprazan-based concomitant and bismuth quadruple therapies. METHODS: We retrospectively analyzed data from patients with H. pylori infection who received either 10-day tegoprazan-based concomitant therapy or 14-day tegoprazan-based bismuth quadruple therapy as first-line treatment. The primary outcome was H. pylori eradication rate, with secondary outcomes including adverse events and insufficient medication rates. RESULTS: Among the 1082 patients included in the study, 620 and 462 were treated with tegoprazan-based concomitant and bismuth quadruple therapies, respectively. Intention-to-treat analysis demonstrated no difference in eradication rates between the tegoprazan-based concomitant and bismuth quadruple therapy groups (74.7% [95% confidence interval-CI, 71.1-78.0%] vs 74.7% [95% CI, 70.6-78.5%], P = 0.999). Per-protocol analysis also showed similar eradication rates between the two groups (88.0% [95% CI, 85.0-90.6%] vs 89.7% [95% CI, 86.3-92.5%], P = 0.424). The overall adverse event rates (49.6% vs 39.2%, P = 0.001) and insufficient medication rates (4.8% vs 2.4%, P = 0.036) were higher in the bismuth quadruple therapy group than in the concomitant therapy group. CONCLUSIONS: The eradication rates of tegoprazan-based 10-day concomitant therapy and 14-day bismuth quadruple therapy were comparable. However, because of its shorter treatment duration, better medical adherence, and lower incidence of adverse events, tegoprazan-based concomitant therapy may be preferable in regions with high rates of clarithromycin and metronidazole resistance.
