title: [Lansoprazole versus ranitidine bismuth citrate containing triple regimens for Helicobacter pylori eradication in patients with duodenal ulcer].
abstract: The aim of this study was to compare in an open, controlled and prospective trial the efficacy of one-week regimen using either lansoprazole (2 x 30 mg) + 2 x 500 mg metronidazole + 2 x 250 mg clarithromycin (group I, 60 cases) or ranitidine bismuth citrate (2 x 400 mg) + 2 x 500 mg metronidazole + 2 x 250 mg clarithromycin (group II, 61 cases) on the eradication of Hp infection in duodenal ulcer patients. The diagnosis was stated endoscopically. Hp infection was confirmed from 2 antral + 2 corporeal biopsies by the modified Giemsa stain and rapid urease test. After eradication the patients were given on-demand treatment with 30 mg lansoprazole (group I) or 2 x 150 mg ranitidine (group II). Control 13C-urea breath test was performed 4-6 weeks after eradication. On intention to treat basis, Hp was eradicated in 78.3% (confidence interval, CI: 67.6-89.1%) in group I and 78.7% (CI: 68.1-89.2%) in group II (p > 0.05). Per protocol eradication rates were 92.1% (CI: 84.5-99.7%) in group I and 90.5 (CI: 82.4-98.6%) in group II (p > 0.05). Side effects were recorded in 13.5% in group I and 18.3% of cases in group II. Short term triple therapies using either lansoprazole or ranitidine bismuth citrate + 2 antimicrobials were effective and safe in the eradication of Hp in duodenal ulcer patients.
