An Updated Meta-Analysis on the Association Between Celiac Disease and Cardiovascular Diseases

Abstract

Objectives: Research on the relationship between celiac disease (CD) and cardiovascular disease (CVD) is still ongoing, and different studies have reported contradictory findings. To carry out a meta-analysis and systematic review to look into the connection between CD and CVD risk. Methods: A thorough search was conducted in PubMed, Scopus, and Google Scholar databases up to February 19, 2024. Relevant articles were extracted, and the titles, abstracts, and full texts of the related articles were screened. The quality of the studies was assessed using the Joanna Briggs Institute critical appraisal tools. Results: Nine cohort and one case-control studies involving 49,621,333 individuals were included in the meta-analysis. The pooled analysis revealed a 7% increased risk of CVD in CD patients compared to controls (OR: 1.07, 95% CI: 1.03-1.10, P < 0.05). Significant heterogeneity was observed among studies (I2 = 76%, P < 0.001). Conclusion: This meta-analysis provides evidence of a modest but significant increase in CVD risk in patients with CD. The results highlight the importance of considering cardiovascular health in CD treatment and the need for further research to elucidate the mechanisms underlying this association and to develop targeted prevention strategies.
