7-day versus 14-day tegoprazan-based triple therapy to treat Helicobacter pylori infection: Real-world evidence
Abstract
BACKGROUND AND AIM: Potassium-competitive acid blockers (P-CABs) can be used to eradicate Helicobacter pylori infection. We aimed to evaluate the impact of treatment duration (7 vs 14 days) on successful H. pylori eradication with P-CAB-based triple therapy in Korea, where clarithromycin resistance rate is high.
METHODS: We retrospectively reviewed the data of patients who received first-line treatment for H. pylori infection with tegoprazan-based triple therapy (50 mg tegoprazan + 1000 mg amoxicillin + 500 mg clarithromycin twice daily for 1 or 2 weeks). The primary endpoint was the eradication rate in intention-to-treat (ITT) analysis.
RESULTS: Of the 948 patients included in the study, 435 and 513 received 7-day and 14-day tegoprazan-based triple therapy, respectively. The eradication rate was higher in the 14-day therapy group than in the 7-day therapy group (ITT, 63.9%; 95% confidence interval [CI], 59.3-68.3%] vs 78.6% [95% CI, 74.9-81.9%], respectively, P < 0.001; per-protocol, 70.5% [95% CI, 65.8-74.8%] vs 85.1% [81.7-88.1%], respectively, P < 0.001). Overall adverse event rates did not differ between the two groups. Although six patients in the 14-day treatment group discontinued the prescribed medications due to adverse events, four of them (67%) discontinued the medication within 4 days.
CONCLUSIONS: The 14-day tegoprazan-based triple therapy showed a superior eradication rate and acceptable adverse events compared with the 7-day tegoprazan-based triple therapy. A…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 948 participants or records.
