BACKGROUND: Bismuth quadruple (BQ) therapy is known to have poor patient compliance and a complex dosing method, and no appropriate third-line regimen exists if second-line BQ therapy fails. In Korea, some alternative regimens have shown unsatisfactory eradication rates. Therefore, we investigated the success rates of the second-line moxifloxacin-rifabutin triple (MRT) regimen and compared it with BQ regimen in subgroup analysis of peptic ulcer patients.
MATERIALS AND METHODS: This study was a retrospective study of 71 patients who underwent a second-line MRT for Helicobacter pylori after failing to clarithromycin triple regimen. To compare the eradication rate in gastric ulcer patients, 51 patients in the MRT group and 132 patients in BQ group were included. After age and sex propensity matching, 45 patients were included in each group (the alpha value and power were set at 0.05% and 77%, respectively).
RESULTS: The eradication rate in the MRT group was 69.0% (49/71) in the intention-to-treat (ITT) analysis and 77.8% (49/63) in the per-protocol (PP) analysis. These were significantly lower than the eradication rate in the BQ group (82.5%, p = 0.019 in the ITT analysis; 89.3%, p = 0.022 in the PP analysis). In subgroup analysis of peptic ulcer patients, the success rate of BQ group was significantly higher than that of MRT group in both ITT and PP populations (81.8% (108/132) vs. 60.8% (31/51) in the ITT populations, p = 0.004; and 90.0% (108/120) vs. 72.1% (31/43) in the PP populations, p = 0.010). Among the 14 patients with MRT therapy failure, 10 were eradicated with BQ as the third-line regimen. The eradication rate of the third-line BQ after the second-line MRT failure was 90.0% (9/10).
CONCLUSION: Second-line MRT therapy was not as effective as BQ therapy, so it should be considered for limited use only when BQ is not available.
