Moxifloxacine plus amoxicillin and ranitidine bismuth citrate or esomeprazole triple therapies for Helicobacter pylori infection
Abstract
Up to 20% of patients, or even more, will fail to obtain eradication after a standard triple therapy. The aim of this study is to evaluate the efficacy of moxifloxacine-containing regimens in the first-line treatment of Helicobacter pylori. One hundred and twenty H. pylori-positive patients were randomized into four groups to receive one of the following 14-day treatments: ranitidine bismuth citrate (RBC) 400 mg b.d. plus amoxicillin 1 g b.d. and clarithromycin 500 mg b.d. (RAC group, n = 30); RBC 400 mg b.d. plus moxifloxacine 400 mg o.d. and amoxicillin 1,000 mg b.d. (RAM group, n = 30); esomeprazole 40 mg b.d. plus amoxicillin 1,000 mg b.d. plus clarithromycin 500 mg b.d. (EAC group, n = 30); and esomeprazole 40 mg b.d. plus amoxicillin 1,000 mg b.d. plus moxifloxacine 400 mg o.d. (EAM group, n = 30). Eradication was assessed by (13)C urea breath test 8 weeks after therapy. Per-protocol and intention-to-treat eradication was achieved in 23 out of 30 patients (76.7%, 95% confidence interval [CI]: 61-92) in the RAC group, in 20 patients (66.7%, 95% CI: 49-84) in the RAM group, in 16 patients in the EAM group (53.3%, 95% CI: 34-71), and in 19 patients in the EAC group (63.3%, 95% CI: 54-72). Mild or moderate side-effects were significantly more common in the EAM group (70%) compared to the RAC (36.6%), RAM (43.3%), and EAC (56.6%) groups (P = 0.03). From our results, we conclude that moxifloxacine-containing triple therapies have neither eradication nor compliance advantages…
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. Reported size: 30 participants or records.
