Abstract
INTRODUCTION: Suppression of gastric acid secretion with proton-pump inhibitors (PPI) is an integral part of the treatment of Helicobacter pylori infection. Esomeprazole has been shown to be superior to other PPIs when used in the context of triple therapy; however, comparative data for PPI efficacy in quadruple therapy are lacking. Current guidelines recommend H. pylori eradication with quadruple therapy in areas with high clarithromycin resistance. OBJECTIVE: To determine whether esomeprazole is more effective than other PPIs in the context of quadruple therapy for H. pylori eradication. METHODS: We retrospectively identified 25- to 60-year-old subjects with a positive 13C-urea breath test and no prior laboratory or endoscopic test for H. pylori infection. Pharmacy dispensation data were retrieved. RESULTS: A total of 7,896 subjects including 2,856 (36.2%) males, aged 40.4 ± 10.6 years, were identified. Of those, 78.1% received omeprazole, 20.1% received lansoprazole, 1.5% received esomeprazole, and 0.34% received pantoprazole together with antibiotics for H. pylori eradication. Esomeprazole was associated with a greater proportion of successful eradication (85.0 vs. 77.5%, esomeprazole vs. omeprazole, OR 1.64; 95% CI 0.99-2.72; p = 0.05). A nonsignificant trend favored esomeprazole over omeprazole among subjects receiving quadruple therapy (90.0 vs. 82.0%, respectively, OR 1.98; 95% CI 0.68-5.72; p = 0.16). Independent predictors of treatment success included older age and quadruple therapy. CONCLUSION: Esomeprazole is more beneficial than other PPIs for H. pylori eradication. Studies with larger subgroups are necessary to confirm our findings among subjects receiving quadruple therapy.
