[10-day triple therapy with esomeprazole 40 mg/12 h vs. quadruple concomitant non-bismuth therapy as first line treatment for Helicobacter pylori infection].

Abstract Introduction Quadruple concomitant non-bismuth therapy has recently become the most widely prescribed first-line treatment for Helicobacter pylori infection in Spain. Whether optimised conventional triple therapy can achieve comparable efficacy rates remains to be seen. Materials and methods Retrospective study comparing the efficacy of triple and quadruple concomitant therapy, and sub-analysis following administration of both for 10 days with esomeprazole 40 mg/12 h. Results A first-line therapy was administered to 657 patients from 1st January 2012 to 31st December 2014. Quadruple therapy (n = 371) showed higher efficacy than triple therapy (n = 248) for both intention-to-treat (85.9% vs. 65.7%; P P P  = .003) and per protocol analysis (92.5% vs.74.6%; P  = .002). Conclusions Quadruple concomitant therapy with high dose proton pump inhibitor (PPI) for 10 days achieves a significantly higher eradication outcome than optimised triple therapy, with rates of over 90% when the PPI prescribed is esomeprazole 40 mg/12 h.
