title: High effectiveness and safety of one-week antibiotic regimen in Helicobacter pylori eradication.
abstract: BACKGROUND
  Helicobacter pylori is strongly associated with peptic ulcer: H. pylori eradication markedly decreases the recurrence rate of duodenal and gastric ulcer, but the optimum length of antibiotic therapy in the eradication of H. pylori is still unclear.
  
  
  OBJECTIVE
  To verify the effectiveness and side-effect profile of an eradicating regimen consisting of omeprazole 20 mg daily for 4 weeks and, during the first week, combination antimicrobial treatment with tinidazole 500 mg b.d. plus clarithromycin 250 mg b.d. in patients with active duodenal and gastric ulcer.
  
  
  METHODS
  One hundred and ninety-six duodenal ulcer patients and 27 gastric ulcer patients with H. pylori infection were admitted into an open prospective study. Compliance was assessed by an accurate interview.
  
  
  RESULTS
  Overall, H. pylori was successfully eradicated in 201 of 223 patients (intention-to-treat 90.1%; 95% CI = 85-94%): 176 of 196 duodenal ulcer patients became H. pylori-negative (89.8%; CI = 85-94%) as well as 25 of 27 gastric ulcer patients (92.6%; CI = 76-99%). Compliance was excellent in 221 of 223 (99.1%) patients evaluated as having taken all the medication as prescribed. Sixteen patients (7.2%) developed mild side effects during treatment.
  
  
  CONCLUSIONS
  This combination treatment had excellent results with almost absolute compliance and a very low rate of minor side effects.
