Abstract PURPOSE: The aim of this study was to assess and compare the efficacies of proton pump inhibitor-based triple therapy and bismuth-based quadruple therapy as first-line treatments for Helicobacter pylori eradication in Korean children. METHODS: We retrospectively reviewed the data of children who had been diagnosed with H. pylori infection at the Seoul National University Bundang Hospital from March 2004 to August 2012. The patients were randomly assigned to receive either triple therapy consisting of omeprazole, amoxicillin, and clarithromycin for 2 weeks (OAC group) or quadruple therapy comprising omeprazole, amoxicillin, metronidazole, and bismuth salts for 1 week (OAMB group). The patients were evaluated for eradication of H. pylori infection at 4 weeks after the completion of the treatment. RESULTS: Of the 129 children enrolled in this study, 118 (91.5\%) were included in the final analysis. The eradication rates in OAC and OAMB groups were 67.7\% (42/62) and 83.9\% (47/56), respectively, which were significantly different between the 2 treatment groups (p=0.041). The eradication rates in the OAMB group during the periods 2004-2006, 2007-2009, and 2010-2012 were superior to those in the OAC group. CONCLUSION: This study indicated that the 1-week bismuth-based quadruple therapy, compared with the standard 2-week triple therapy, was significantly more successful in eradicating H. pylori infection in Korean children.
