Successful Helicobacter pylori eradication incorporating a one-week antibiotic regimen.
BACKGROUND
The optimum regimen for the eradication of Helicobacter pylori remains unclear. The aim of this study was to determine the efficacy and tolerability of omeprazole 40 mg daily given for 2 weeks, plus amoxycillin 500 mg t.d.s. and metronidazole 400 mg t.d.s. given for the first 7 days, in the treatment of H. pylori associated peptic ulcer disease.


RESULTS
One hundred and thirty-two consecutive patients with peptic ulcer disease were entered into the study (89 male, 41 female; median age 47 years; inter-quartile range: 36-58 years). H. pylori was eradicated successfully in 109 of 130 patients (intention-to-treat: 83%; 95% confidence limits: 76-89%); per protocol: 85% (95% CI: 78-91%)). Ninety per cent of patients completed the full course of therapy. Only four patients (3%) stopped treatment as a result of side effects although these occurred in 41% of patients. One patient developed pseudomembranous colitis requiring hospital admission.


CONCLUSIONS
Omeprazole combined with one week of treatment of amoxycillin and metronidazole is an effective and well tolerated Helicobacter eradication regimen. Occasional severe side effects remain a risk, even when the duration of antibiotic exposure is reduced.
