Abstract

Objective

This meta-analysis was designed to provide new insights into the relationship between Helicobacter pylori (H. pylori) infection and recurrent aphthous stomatitis (RAS).

Materials and methods

We included and evaluated studies on H. pylori infection and RAS from PubMed, EMBASE, Cochrane Library, and Web of Science databases published up to January 31, 2023. The characteristics of these studies were collected, and the quality was evaluated by Newcastle-Ottawa Scale (NOS). The random effects model was used to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). To further explore the sources of heterogeneity, meta-regression analysis and subgroup analyses were performed. Funnel plot, Egger’s test, and Begg’s test were used to assess publication bias.

Results

In total, fifteen case-control studies with 1137 individuals (601 cases and 536 controls) were included. The H. pylori was found to be significantly associated with RAS (OR: 1.83 95% CI: 1.41–2.37, P = 0.001). In the subgroup analyses, studies that used PCR (OR: 2.03 95% CI: 1.31–3.15) or UBT (OR: 1.83 95% CI: 1.13–2.96) yielded a significant positive association, while a non-significant association (OR: 1.12 95% CI: 0.61–2.08) was found from studies that used ELISA method. Sensitivity analyses showed that the results were robust. No significant publication bias was found.

Conclusions

The current evidence does not rule out an association between H. pylori and RAS. The effect of H. pylori on RAS varies in detection methods and sources of sample. Large samples, multiple clinical studies, and improved methods are still needed to determine the exact effect of H. pylori on RAS.

Clinical significance

H. pylori infection may be a risk factor for the pathogenesis of RAS.
