Effectiveness of 7-Day and 14-Day Moxifloxacin-Dexlansoprazole Based Triple Therapy and Probiotic Supplement for Helicobacter Pylori Eradication in Thai Patients with Non-Ulcer Dyspepsia: A Double-Blind Randomized Placebo-Controlled Study
Abstract
Background: Helicobacter pylori (H. pylori) is important cause of peptic ulcer and gastric cancer. Moxifloxacin is effective antibiotic for treatment for H. pylori. However, there were limited studies as first line therapy. Probiotics had been shown to decrease therapy-related side-effect and increase eradication rate. Aim of this study was to evaluate the efficacy of moxifloxacin-dexlansoprazole based triple therapy with probiotic for H. pylori treatment in Thailand. Methods: Patients with H. pylori infected gastritis were randomized to receive 7- or 14-day moxifloxacin-dexlansoprazole based triple therapy with probiotic or placebo. Regimen consisted of 60 mg dexlansoprazole twice daily, 400mg moxifloxacin once daily, 1g clarithromycin MR once daily. Probiotic used in this study was 282.5mg Saccharomyces boulardii (S. boulardii) in capsule prescribed twice daily. CYP2C19 genotyping, antibiotic susceptibility tests, and CagA genotyping were also done. Successful eradication was defined as a negative 13C-urea breath test at least 4 weeks after treatment. Results: Total of 108 subjects was enrolled (27 each to 7- and 14-day regimens with probiotic or placebo). Antibiotic susceptibility tests showed 29% fluoroquinolone, 19% metronidazole and 4% clarithromycin resistance. CYP2C19 genotyping demonstrated 43%, 47% and 11% were rapid, intermediate and poor metabolizers, respectively. CagA genes were positive in all patients. Eradication rates of 7-day and 14-day regimens with…
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: 108 participants or records.
