Association between type 1 diabetes mellitus and esophageal varices: a Mendelian randomization study

Introduction Esophageal varices (EV) are dilated submucosal veins in the distal esophagus connecting the portal vein to the systemic circulation. Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease associated with a variety of cardiovascular and peripheral vascular diseases. The aim of t...

description Introduction Esophageal varices (EV) are dilated submucosal veins in the distal esophagus connecting the portal vein to the systemic circulation. Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease associated with a variety of cardiovascular and peripheral vascular diseases. The aim of this study was to investigate the causal relationship between T1DM and EV from a genetic perspective. Material and methods We performed a genome-wide association study of the causal relationship between T1DM and EV using pooled data from the GWAS database. Firstly, we conducted a two-sample Mendelian randomization (MR) study of these two diseases. Next, we used multivariate Mendelian randomization (MVMR) to further confirm the effect of type 1 diabetes on esophageal varices after excluding confounding factors such as cirrhosis and immune system disorders associated with type 1 diabetes mellitus. Sensitivity analyses were performed using Cochran’s Q test, MR-Egger intercept, MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) methods, leave-one-out analysis and funnel plots. Results In all two-sample MR analyses, the p -values of the IVW were all 1, and the directions of the IVW and MR-Egger assays were consistent. No horizontal pleiotropy was found for the MR-Egger intercept, and leave-one out analysis showed that the results remained stable after the removal of individual SNPs. MVMR analysis showed that the causal relationship between type 1 diabetes mellitus and esophageal varices persisted after exclusion of immune-related confounders. Conclusions The results of the MR analysis supported a causal relationship between T1DM and EV risk.
