Triple regimens using lansoprazole or ranitidine bismuth citrate for Helicobacter pylori eradication
Abstract
BACKGROUND: A combination of an antisecretory agent with two antibiotics is considered the 'gold standard' for Helicobacter pylori eradication.
OBJECTIVES: To compare the eradication rates and the safety profile of two short-term triple therapies containing lansoprazole (L) or ranitidine bismuth citrate (RBC) as antisecretory agents.
METHODS: One hundred and twelve H. pylori-positive patients either with peptic ulcer (56 duodenal ulcers: 25 active and 31 with a history of ulcer; 13 gastric ulcers: nine active and four with a history of ulcer) or gastritis (43) were included in an open, randomized, controlled trial. H. pylori infection was initially detected by CLO-test and histology on antral and corpus biopsies. H. pylori-positive patients were randomized to receive L plus clarithromycin (C) 250 mg b.d. plus tinidazole (T) 500 mg b.d. (LCT) or RBC plus C 250 mg b.d. and T 500 mg b.d. for 7 days (RbcCT). L or RBC were administered for a further 3 weeks in patients with active peptic ulcers. A second endoscopy was performed at least 6 weeks after the end of therapy for the assessment of H. pylori infection by CLO-test and histology. Eradication was assumed if all the tests were negative for H. pylori.
RESULTS: Forty-eight patients in the LCT group and 4 5 in the RbcCT group were assessed for H. pylori eradication. The eradication rates, according to intention-to-treat (ITT) and per protocol (PP) analyses were, respectively, 76.8% and 89.5% for the LCT group, and 73.2% and…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
