Abstract
Background Previous studies showed inconsistent results regarding associations between inflammatory bowel disease (IBD) and risk of ischemic heart disease (IHD) and diabetes. The present study aimed to make a meta-analysis to assess the risk of IHD and diabetes in IBD.
Methods We searched for articles published before February 2020 in the databases as follows: PubMed, Web of Science, Medline, EMBASE, and Google Scholar. We computed odds ratio (OR) or relative risk (RR) and 95 % confidence intervals (CI) regarding the association between IBD and risk of IHD or diabetes by using STATA 13.0 software.
Results The present meta-analysis showed that IBD was associated with higher risk of IHD (OR/RR = 1.26, 95 % CI 1.20 to 1.32, I2 = 88.3 %, p < 0.0001). Additionally, both ulcerative colitis (UC) and Crohn’s disease (CD) were associated with higher risk of IHD (UC: OR/RR = 1.19, 95 % CI 1.13 to 1.26, I2 = 65.6 %, p = 0.001; CD: OR/RR = 1.33, 95 % CI 1.17 to 1.51, I2 = 89.5 %, p < 0.0001). The study showed that IBD was associated with elevated risk of diabetes (OR/RR = 1.26, 95 % CI 1.03 to 1.53, I2 = 92.1 %, I2 = 92.1 %, p < 0.0001). Additionally, both UC and CD were associated with higher risk of diabetes (UC: OR/RR = 1.33, 95 % CI 1.03 to 1.71, I2 = 93.8 %, p < 0.0001; CD: OR/RR = 1.39, 95 % CI 1.10 to 1.76, I2 = 76.7 %, p = 0.002).
Conclusion In conclusion, patients with IBD are at increased risk of IHD and diabetes. Thus, regular monitoring of biomarkers of IHD and blood glucose levels should be considered for the early detection of IHD and diabetes in IBD patients.
