4-day triple therapy with rabeprazole, amoxicillin and clarithromycin in the eradication of Helicobacter pylori in patients with peptic ulcer disease--A pilot study.
BACKGROUND
It is well established that a 7-day triple therapy achieves eradication rates of Helicobacter pylori between 90% and 95%. Due to a lack of highly effective short-term eradication studies the aim of the present pilot study was to investigate the effect of a 4-day triple therapy with the new proton pump inhibitor rabeprazole (20 mg b. i. d.) in combination with clarithromycin (500 mg b. i. d.) and amoxicillin (1 g b. i. d.) without acid-suppressive pre-treatment in patients with H. pylori-related peptic ulcer disease.


METHODS
20 patients (11 men, 9 women) with endoscopically diagnosed peptic ulcers (gastric ulcer: n = 5; duodenal ulcer: n = 9; combined gastric and duodenal ulcer: n = 2, gastric or duodenal ulcer scars: n = 4) and H. pylori infection were consecutively recruited. The Helicobacter pylori status was assessed by means of histology, CLO (urea-) test and C13-urea breath test (C13-UBT) at entry. Treatment success was determined by C13-UBT 35-42 days after end of treatment.


RESULTS
In 18 out of the 20 patients (90%) [77-100%, 95%-CI] a negative test result was found in C13-UBT 35-42 days after treatment. The 2 patients who remained H. pylori-positive had a duodenal ulcer.


CONCLUSIONS
A 4-day triple therapy of rabeprazole in combination with clarithromycin and amoxicillin seems to be highly effective in eradicating H. pylori and well tolerated in patients with gastric and duodenal ulcer disease. The achieved eradication rate of 90% is comparable with the established 7-day triple therapy regimens. On the basis of these results and considering costs, side effects and compliance a large number of patients should be enrolled in a confirmatory 4-day eradication trial.
