AimSystematization of data on the efficacy and safety of butyric acid inclusion in eradication therapy (ET) regimens for Helicobacter pylori infection.MethodsResearch searches were carried out in the electronic databases MEDLINE/PubMed, EMBASE, Cochrane, Google Scholar, the Russian Science Citation Index (RSCI) until November 2020. All controlled studies comparing the efficacy and/or safety of including butyric acid in ET regimens for H. pylori infection were included in the final analysis.ResultsThe meta-analysis included 6 controlled studies (1 Italy, 5 Russia) involving 736 patients (381 in the ET groups with butyric acid; 355 in the comparison groups). The pooled eradication efficiency in the butyric acid groups was 90.23% (95% confidence interval CI 86.73493.069), while in the comparison groups it was 65.69% (95% CI 60.44170.669). Meta-analysis showed that the addition of butyric acid to ET regimens significantly increased the eradication efficiency (odds ratio OR 5.355, 95% CI 3.5048.184; p0.001). There was no significant heterogeneity between results (p=0.1408; I2=42.1%). The addition of butyric acid to ET regimens significantly reduces the risk of diarrhea (OR 0.225, 95% CI 0.09230.549; p=0.001; I2=34.21%) and abdominal distention (OR 0.357, 95% CI 0.1550.818; p=0.015; I2=80.13%) by the end of the 1st week of treatment.ConclusionThe present meta-analysis demonstrated that the inclusion of butyric acid in ET regimens for H. pylori infection significantly increases the effectiveness of treatment and reduce the incidence of side effects. Apparently, the increase in the effectiveness of eradication is due to an increase in patient compliance with treatment due to an improvement in the safety profile of therapy.
