ABSTRACT
BACKGROUND:
Non-bismuth containing quadruple therapy (concomitant therapy) is an alternative treatment for Helicobacter pylori (H. pylori) eradication with increasing clarithromycin-resistant strains over times. This study compared the efficacies of non-bismuth containing quadruple therapy (concomitant therapy) in the treatment of first-line anti-Helicobacter Pylori between two time intervals (January 2013 to June 2014 and June 2016 to December 2017).METHODS:
H. pylori-infected patients were recruited in the intention-to-treat (ITT analysis) and divided into EACM-A group (enrolled from January 2013 to June 2014, N = 98) and EACM-B group (enrolled from June 2016 to December 2017, N = 99). Patients were prescribed with 7-day esomeprazole 40 mg bid., clarithromycin 500 mg bid., amoxicillin 1 g bid. and metronidazole 500 mg bid. Ninety patients and 93 patients were analyzed in the per protocol (PP) analysis (8 and 6 patients lost follow-up in each group). Urea breath tests were performed 4-8 weeks thereafter.RESULTS:
The eradication rates for EACM-A and EACM-B groups were 87.8% (95% confidence interval [CI] = 79.7%-93.5%) and 84.8% (95% CI = 76.2%-91.2%) (p = 0.55) in intention-to-treat (ITT) analysis; 95.6% (95% CI = 89.1%-98.8%) and 90.3% (95% CI = 82.4%-95.5%) (p = 0.17) in per protocol (PP) analysis. The adverse event rates were 16.7% vs. 10.8% in the 2 groups (p = 0. 0.24). The antibiotic resistance rates between the 2 groups were amoxicillin (0%), tetracycline (0%); clarithromycin (11.8% vs. 17.8%, p = 0.46); metronidazole (32.4% vs. 33.3%, p = 0.93) and levofloxacin (14.7% vs. 37.8%, p = 0.02).CONCLUSION:
The success rate of 7-days concomitant therapy encountered an approximately 5% decrease across 4-year time interval (2013-2017) with the changes of clarithromycin resistance from 11.8% to 17.8% in Taiwan.Palabras clave
