title: Eradication of Helicobacter pylori reduces the rate of duodenal ulcer rebleeding: a long-term follow-up study.
abstract: OBJECTIVE
  The long-term efficacy of Helicobacter pylori eradication to reduce the rate of recurrence of peptic ulcer bleeding is still uncertain. We evaluated the rate of duodenal ulcer rebleeding for 48 months after H. pylori eradication.
  
  
  METHODS
  Thirty-two male patients with H. pylori infection and duodenal ulcer bleeding were treated with omeprazole (40 mg/day for 4 wk), colloidal bismuth (480 mg/day for 2 wk), amoxicillin (2 g/day for 1 wk), and metronidazole (750 mg/day for 1 wk), and followed up for 48 months. Endoscopy and tests for H. pylori infection were repeated every year.
  
  
  RESULTS
  Ulcer healed in all patients, but H. pylori infection persisted or recurred in 11 patients. Within 48 months, rebleeding occurred in nine (81.8%) of these patients, whereas the 21 patients who were persistently negative for H. pylori infection remained asymptomatic without rebleeding (0/ 21 = 0%, p < 0.002) during the whole follow-up.
  
  
  CONCLUSIONS
  Eradication of H. pylori can reduce the rate of duodenal ulcer rebleeding for at least 4 yr, thus potentially modifying the natural history of the disease.
