OBJECTIVES: To determine the long-term outcomes in terms of Helicobacter pylori and ulcer recurrence after second-line eradication with bismuth-containing quadruple regimens in Korea. METHODS: Sixty-seven patients with peptic ulcer disease after successful eradication using second-line quadruple therapies were prospectively followed up 1 month after treatment and then every 6 months or when dyspeptic symptoms reappeared to ascertain H. pylori and ulcer status. RESULTS: Three patients were lost during follow-up. The median duration of follow-up of the remaining 64 patients was 26.8 months. H. pylori recurrence occurred in 11 of these 64 patients (17.2%), giving a calculated reinfection rate of 6.0% per patient-year. Only one of the 11 patients was reinfected by 12 months after treatment completion. Four of 11 patients (36.4%) who became reinfected experienced peptic ulcer recurrence, but none of 53 patients who were not reinfected experienced recurrence. No evidence was obtained to indicate that the reinfection rate depended on the age, sex, ulcer location, or eradication regimens. The relapse of dyspeptic symptoms was the only factor predictive of H. pylori recurrence. CONCLUSION: This study suggests that the recurrence rate of H. pylori at 1 year after second-line, bismuth-containing quadruple therapy is low, but the annual reinfection rate is as high as 6%. Surveillance for H. pylori reinfection facilitating peptic ulcer recurrence may be warranted even after a second eradication, especially when dyspeptic symptoms reappear in Korea.
