Helicobacter pylori may have a protective effect against inflammatory bowel disease (IBD). We integrated epidemiological data to identify the correlation between IBD and H. pylori. Moreover, we analyzed whether IBD medication and classification affect H. pylori, and whether eradication of H. pylori leads to recurrence of IBD. ⋯ H. pylori prevalence was negatively correlated to IBD and H. pylori had a protective effect against IBD. Furthermore, eradication of H. pylori can lead to recurrence of IBD.
