    Abstract:
    BACKGROUND: Helicobacter pylori (Hp) infection predisposes to malignant and non-malignant diseases warranting eradication. In Belgium, resistance rates for clarithromycin demonstrate regional variations making the use of standard triple therapy (STT) borderline acceptable. According to a recent Belgian survey, STT and bismuth-based quadruple therapy (BQT), are equally frequent prescribed as first line treatment for treatment naïve Hp positive patients. This study aims to evaluate the eradication rates (ER) of BQT versus STT. METHODS: Multicentre, non-blinded randomized, prospective study comparing ER in treatment-naïve Hp positive patients. ER were compared by intention to treat (ITT) and per protocol (PP) analysis. RESULTS: Overall 250 patients were included (STT 126, BQT 124). Seventeen patients were lost to follow-up (6,8%). No significant difference in ER between BQT and STT was observed in ITT (73% vs 68%, p= 0,54) neither in PP analysis (81% vs 75%, p= 0,33). Side effects and endoscopic findings were comparable between groups. Post-hoc analysis showed no differences according to gender or site allocation. CONCLUSION: The numerical advantage of BQT did not translate in a significant improvement of ER when compared with STT. These results question the cost-effectiveness of BQT, while confirming the suboptimal eradication rates on STT. A nationwide monitoring of resistance patterns, maximal investments in treatment adherence as well as a detailed follow-up of the changing treatment landscape are mandatory to continuously optimise Hp ER in Belgium.
