Failure of Helicobacter pylori eradication has increased over the past decade and is related to increased antibiotic resistance. The aim of this study was to estimate the eradication rates of H. pylori infection over the past 9 years in a single center. MATERIALS AND METHODS: From 2004 to 2013, a total of 5,715 patients were diagnosed with H. pylori infection and were prescribed first line triple regimens. 2,482 patients underwent tests for assessment of eradication by 13C-urea breath test, rapid urease test or histopathological examinations. RESULTS: The overall eradication rate of first line triple regimen was 80.4% and continually decreased during the study period (P=0.011). Among the triple regimens, the eradication rate of two-week and one-week regimens were 90.1% and 79.3%, each. The two-week regimen was superior to the one-week regimen (P=0.000). The overall eradication rates of second line quadruple regimen was 91.4% and there was no significant decrease in the annual eradication rates (P=0.708). The overall eradication rates of both first line and second line therapy were 81.9% and decreased gradually during the study period (P=0.011). Multivariate analysis revealed sex, age, type of proton pump inhibitor, and duration of eradication to be associated with eradication failure. CONCLUSIONS: The eradication rates of first line triple regimen has decreased gradually; however, the eradication rates of second line regimen remains unchanged. Triple regimens of two-weeks seem to be better than one.
