Salvia mirzayanii Rech. f. & Esfand as adjunctive therapy for Helicobacter pylori eradication:a randomized controlled trial

OBJECTIVE: To evaluate the effect of this plant as adjunctive therapy on Helicobacter pylori(H. pylori) eradication. METHODS: The plant capsules were prepared and their physicochemical properties were assessed. In this clinical trial, 99 patients with H. pylori infection were randomized to receive Salvia mirzayanii Rech. f. & Esfand(S. mirzayanii) or placebo capsules for two weeks. All the patients in both groups received clarithromycin-based triple therapy. Both intention to treat and per protocol analyses were performed. Eradication rates, treatment side effects, and medication compliance were evaluated in both groups. RESULTS: H. pylori eradication rate of all the randomized participants was 59.59%. The eradication rate of H. pylori was significantly higher in S. mirzayanii group compared with that in the placebo group for per protocol analysis(84.62%, P = 0.026) but not for intention to treat one(65.31%, P = 0.252). There were no significant differences between the two groups regarding the frequencies of the medications side effects and the patients with poor compliance. CONCLUSION: The use of S. mirzayanii as adjunctive therapy to 14-day clarithromycin-based triple therapy might improve H. pylori eradication rate.
