    Notes: There is controversy about the effect of acid-suppressive therapy on Helicobacter pylori density and the severity of histological gastritis in the corpus.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To evaluate the precise distribution of H. pylori, both on the surface mucus cells and in the surface mucus gel layer, by using Carnoy’s fixation and immunostaining for the detection of bacteria.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:A total of 19 peptic ulcer patients with H. pylori infection were studied. All patients received a 6-week course of treatment with omeprazole (20 mg/day). Before and after the therapy, H. pylori density in Carnoy-fixed tissue sections was examined immunohistochemically. The effect of omeprazole therapy on the severity of gastritis was also evaluated.〈section xml:id="abs1-4"〉〈title type="main"〉Results: H. pylori density and the grade of gastritis significantly decreased in the antrum after omeprazole therapy. In the corpus, however, there were no significant changes in H. pylori density or the severity of gastritis after omeprazole therapy.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion:Carnoy’s fixation and immunostaining was found to be useful for the detection of H. pylori in the surface mucus gel layer as well as on the surface mucus cells in biopsy tissue sections. By using this method, H. pylori density decreased in the antrum, but remained unchanged in the corpus after a 6-week course of omeprazole therapy.

    Notes: : The cytoprotective agent, ecabet sodium, inhibits urease activity and growth of Helicobacter pylori.〈section xml:id="abs1-2"〉〈title type="main"〉Aim: To evaluate the efficacy and safety of ecabet sodium-based eradication of H. pylori infection, compared with a lansoprazole-based regimen, in a randomized multicentre study.〈section xml:id="abs1-3"〉〈title type="main"〉Subjects and methods: A total of 120 H. pylori-positive patients were assigned to one of two treatment regimens for 2 weeks: ecabet sodium 1 g b.d., amoxicillin 500 mg t.d.s. and clarithromycin 400 mg b.d. (EAC: 60 patients); or lansoprazole 30 mg (o.m.) with the same antimicrobial agents (LAC: 60 patients). Cure of infection was assessed by a 13C-urea breath test 1 month after completion of treatment.〈section xml:id="abs1-4"〉〈title type="main"〉Results: One patient in the EAC group and two in the LAC group did not complete therapy because of an adverse event, and three did not undergo the 13C-urea breath test. Cure rates for the intention-to-treat, all-patients-treated and per protocol analysis in the EAC group were 85%, 86% and 88%, respectively, whereas those in the LAC group were 85%, 88% and 91%. There were no significant differences in cure rate or adverse events between the two regimens.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions: Ecabet sodium in combination with amoxicillin and clarithromycin is as effective as lansoprazole-based eradication therapy for H. pylori.
