One-week triple therapy with omeprazole, amoxycillin and either clarithromycin or metronidazole for cure of Helicobacter pylori infection.
OBJECTIVE
The present study was designed to evaluate the efficacy and tolerability of 1-week triple therapy regimens for Helicobacter pylori.


METHODS
In two consecutive series, 120 patients with proven H. pylori infection and peptic ulcer disease or functional dyspepsia were treated with either omeprazole 20 mg b.d., amoxycillin 1 g b.d. and clarithromycin 250 mg b.d. (OAC; n = 60) or with omeprazole 20 mg b.d., amoxycillin 1 g b.d. and metronidazole 400 mg b.d. over 1 week (OAM; n = 60). H. pylori infection was assessed by rapid urease test, culture and histology before and 4 weeks after cessation of the eradication therapy.


RESULTS
H. pylori eradication succeeded in 53 out of 60 patients by omeprazole-amoxycillin-clarithromycin (OAC) (88%; 95% CI 77-95%) and in 47 out of 60 patients by omeprazole-amoxycillin-metronidazole (OAM) (78%; 95% CI 66-88%) (P = 0.22). Nine patients of each group available for follow-up reported adverse events (15.0 and 15.5%, respectively) without necessity of discontinuation of the study medications. Serious adverse events were not observed.


CONCLUSIONS
Simple and convenient 1-week triple therapies consisting of omeprazole, amoxycillin and either clarithromycin or metronidazole are sufficiently effective in eradicating H. pylori infection.
