Popis: Hybrid therapy is a recommended first-line anti-H. pylori treatment option in the American College of Gastroenterology guidelines, the Bangkok Consensus Report on H. pylori management, and the Taiwan H. pylori Consensus Report. However, the cure rates of eradication therapy in some countries are suboptimal, and the factors affecting the treatment efficacy of hybrid therapy remain unclear. The aim of this study is to identify the independent risk factors predicting eradication failure of hybrid therapy in the first-line treatment of H. pylori infection. A retrospective cohort study was conducted on 589 H. pylori-infected patients who received 14-day hybrid therapy between September 2008 and December 2021 in ten hospitals in Taiwan. The patients received a hybrid therapy containing a dual regimen with a proton pump inhibitor (PPI) plus amoxicillin for an initial 7 days and a quadruple regimen with a PPI plus amoxicillin, metronidazole and clarithromycin for a final 7 days. Post-treatment H. pylori status was assessed at least 4 weeks after completion of treatment. The relationships between eradication rate and 13 host and bacterial factors were investigated via univariate and multivariate analyses. In total, 589 patients infected with H. pylori infection were included in the study. The eradication rates of hybrid therapy were determined as 93.0% (95% confidence interval (CI): 90.9–95.1%), 94.4% (95% CI: 93.8–97.2%) and 95.5%% (95% CI: 93.8–97.2%) by intention-to-treat, modified intention-to-treat and per-protocol analyses, respectively. Univariate analysis showed that the eradication rate of clarithromycin-resistant strains was lower than that of clarithromcyin-susceptible strains (83.3% (45/54) vs. 97.6%% (280/287); p < 0.001). Subjects with poor drug adherence had a lower cure rate than those with good adherence (73.3% (11/15) vs. 95.5% (534/559); p = 0.005). Other factors such as smoking, alcohol drinking, coffee consumption, tea consumption and type of PPI were not significantly associated with cure rate. Multivariate analysis revealed that clarithromcyin resistance of H. pylori and poor drug adherence were independent risk factors related to eradication failure of hybrid therapy with odds ratios of 4.8 (95% CI: 1.5 to 16.1; p = 0.009) and 8.2 (95% CI: 1.5 to 43.5; p = 0.013), respectively. A 14-day hybrid therapy has a high eradication rate for H. pylori infection in Taiwan, while clarithromycin resistance of H. pylori and poor drug adherence are independent risk factors predicting eradication failure of hybrid therapy.
