title: [Ulcer healing through the elimination of Helicobacter pylori: is a week of therapy enough?].
abstract: OBJECTIVE
  To test whether one week's triple therapy with omeprazole and two antibiotics is enough to induce healing of a peptic (gastric and/or duodenal) ulcer.
  
  
  METHODS
  112 Patients (73 males, 39 females; median age 55 [18-88] years) proven by culture or histology to have an Helicobacter (H.) pylori infection and uncomplicated peptic (gastroduodenal) ulcer. For one week they received omeprazole (20 mg once or twice daily) plus two antibiotics (clarithromycin/metronidazole, clarithromycin/tetracycline, clarithromycin/amoxycillin or amoxycillin/metronidazole) to eradicate H. pylori. No further anti-ulcer treatment was given subsequently. Healing of the ulcer and H. pylori status were checked by the urease test, culture and histology (endoscopic biopsy) 4 weeks later.
  
  
  RESULTS
  The 5-week ulcer healing rate was 94.6% (95% confidence interval: 89-98%). Persisting ulcers (n = 6) were associated with either treatment with aspirin or nonsteroidal antiinflammatory drugs (n = 3), persistent H. pylori infection (n = 2) or persistent H. pylori infection plus treatment with aspirin (n = 1). The ulcer healing rate was significantly higher in patients with eradicated infection than in those with posttherapy persistence of H. pylori (97.0 vs. 76.9%; P = 0.02). There were no significant differences after 5 weeks between patients with duodenal and those with gastric ulcer (97.4 vs. 89.3%).
  
  
  CONCLUSIONS
  One-week effective eradication treatment is adequate to induce healing of H. pylori-positive peptic ulcers. Anti-ulcer treatment after eradication of H. pylori should be considered only if the patient is receiving treatment with ulcerogenic drugs or continues to have symptoms.
