Association between Helicobacter pylori infection and irritable bowel syndrome: A systematic review and meta-analysis


Main idea: The study suggests that Helicobacter pylori may have a positive effect on the development of IBS. Although the differences were not statistically significant, there were significant differences among subgroups of patients.


In recent years, the incidence of IBS has gradually increased, and it is considered one of the most common functional gastrointestinal diseases. However, the etiology of IBS is still unclear, and expectations are rising for more targeted treatments. Many clinical trials have explored the link between Helicobacter pylori (H pylori) and IBS with different conclusions. Therefore, we conducted a meta-analysis to explore whether there is an association between H pylori and IBS, which is of great significance for targeted treatment of IBS.

Eight studies, including 1861 patients, assessed the association between H pylori infection and IBS. The OR of H pylori in IBS patients compared to controls was 1.32 (95% CI: 0.94-1.87; P = 0.11).
