    Abstract:
    BACKGROUND: The systematic use of susceptibility testing and tailored first-line treatment for Helicobacter pylori eradication has yet to be established. AIM: To compare 14-day tailored PCR-guided triple therapy to 14-day non-Bismuth concomitant quadruple therapy for first-line Helicobacter pylori eradication. PATIENTS AND METHODS: We performed a multicenter, parallel-group, randomized noninferiority controlled trial. Naive adult patients with Helicobacter pylori infection were treated with 14-day tailored PCR-guided triple therapy (esomeprazole 40 mg and amoxicillin 1000 mg b.d. plus clarithromycin 500 mg or levofloxacin 500 mg b.d. according to clarithromycin susceptibility) or 14-day non-Bismuth concomitant quadruple therapy (esomeprazole 40 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and metronidazole 500 mg b.d.). The primary endpoint was H. pylori eradication. RESULTS: We screened 991 patients for eligibility and randomized 241 patients. The first-line eradication rate was 99.2% in the tailored PCR-guided group and 95.9% in the control group (ITT population; absolute difference of +3.30%, with a lower bound of CI at -0.68%). Both first-line therapies were well tolerated, with a formally significant difference in favor of the tailored PCR-guided group (61.4% vs. 41.2%, p = 0.003). Economic analyses revealed a lower cost of the tailored PCR-guided arm, with a 92% chance of being jointly more effective and less expensive than the control arm in the ITT population. CONCLUSION: In a country with a high level of clarithromycin resistance, the results of our study demonstrated the noninferiority of 14-day tailored PCR-guided triple therapy as a first-line H. pylori eradication therapy compared to 14-day non-Bismuth quadruple therapy (ClinicalTrials.gov NCT02576236).
