title: Effective treatment after failure of omeprazole plus amoxycillin to eradicate Helicobacter pylori infection in peptic ulcer disease.
abstract: METHODS
  Fifty patients with relapsing or complicated Helicobacter pylori positive duodenal (n = 41) or gastric ulcer disease (n = 9) and failure of a combined treatment with omeprazole plus amoxycillin to eradicate H. pylori infection were re-treated with either oral triple therapy (bismuth subsalicylate, metronidazole, tetracycline) plus ranitidine [group I: n = 22] or high-dose omeprazole (40 mg b.d. to t.d.s.) plus amoxycillin (1 g t.d.s.) [group II: n = 28].
  
  
  RESULTS
  Patients of group I and II had similar demographic and clinical characteristics. The overall proportion of eradication of H. pylori infection was 81.8% in group I and 78.6% in group II (P = N.S.) as judged from negative bacterial findings by means of an urease test, specific culture and histology after modified Giemsa stain. Ulcer healing was observed in all patients after a maximum duration of 10 weeks. Ten patients on triple therapy and only one patient on omeprazole plus amoxycillin (45.5% vs. 3.6%; P < 0.001) complained of side effects without necessity of discontinuation of the study medication in either group. Twenty patients (group I: n = 10; group II: n = 10) with relapsing duodenal ulcer disease and successful cure were prospectively followed for one year without any evidence of ulcer relapse or H. pylori re-infection.
  
  
  CONCLUSIONS
  Oral triple therapy plus ranitidine or high-dose omeprazole plus amoxycillin remain highly effective in eradicating H. pylori infection in patients with peptic ulcer disease and treatment failure of omeprazole/amoxycillin, but the omeprazole enhanced antibiotic monotherapy seems to be superior with regard to side effects. Thus, high-dose omeprazole/amoxycillin is recommended as the treatment of first choice in these selected patients. Triple therapy should be reserved for patients intolerant of amoxycillin.
