- W1640321703 abstract "To compare the efficacy of two new one-week triple therapies (with omeprazole, metronidazole and clarithromycin or amoxycillin) for the eradication of Helicobacter pylori and healing duodenal ulcer.Randomised therapeutic trial. Eighty-eight consecutive duodenal ulcer patients with H. pylori infection were studied. At endoscopy, biopsies from both gastric antrum and body were obtained for histologic study (H&E). Two different therapies were administered for one week: omeprazole (O) (20 mg b.i.d.) and metronidazole (M) (500 mg b.i.d.) associated with clarithromycin (C) (500 mg b.i.d.) (group OMC, n = 44) or amoxycillin (A) (1 g b.i.d.) (group OMA, n = 44). Endoscopy with biopsies was repeated one month after completing therapy, and a 13C-urea breath test was also performed. Compliance was evaluated by tablet count. Analysis of data: multiple logistic regression, intention-to-treat. Eradication was defined as the absence of H. pylori by all diagnostic methods.Mean age (standard deviation) was 45(14) years, 75% males. Distribution of variables was similar in both therapeutic groups. Forty-two patients in each group completed the protocol. Eradication was achieved in 90.5% (95% CI = 78-96%) in group OMC and in 57% (42-71%) in group OMA (p < 0.001). In the multivariate analysis the type of therapy was the only variable which influenced on H. pylori eradication (OR = 7.1; CI = 2.2-24; p = 0.001). Ulcer healing was demonstrated in 88% (75-95%) of patients in group OMC and in 71% (56-83%) in group OMA (p = 0.1). Ulcer healing was higher when eradication was achieved (90%; 80-95%) than in H. pylori-positive patients (50%; 31-69%) (p < 0.001). Eradication of H. pylori was the only variable which influenced on ulcer healing (OR = 9.3; CI = 2.8-31; p < 0.001).The new triple therapy with omeprazole, metronidazole and clarithromycin (administered in a twice-a-day basis and only for one week) had an excellent efficacy for the eradication of H. pylori, significantly higher than that obtained with amoxycillin instead of clarithromycin. Both therapies achieved a high ulcer healing rate when H. pylori was eradicated, even with omeprazole administered only for one week." @default.
