Abstract
Background
Diabetes, a growing global public health issue, is often associated with autoimmune liver diseases (AILD), such as autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC), in both type 1 diabetes (T1DM) and type 2 diabetes (T2DM). However, the causal relationship between these conditions remains unclear.
Methods
We used two-sample bidirectional Mendelian randomization (MR) to explore causal links between AILD and diabetes. Genetic variants identified from genome-wide association studies were used as instruments. Sensitivity and multivariable analyses adjusted for potential confounders were performed to assess the robustness of findings.
Results
Genetically predicted PBC (OR 1.41, 95% CI 1.19–1.67) and PSC (OR 1.39, 95% CI 1.14–1.68) were associated with an increased risk of T1DM. PBC (OR 1.03, 95% CI 1.01–1.05) was also linked to a higher risk of T2DM. In reverse MR analysis, genetically predicted T1DM was associated with an increased risk of PBC (OR 1.28, 95% CI 1.09–1.50), PSC (OR 1.27, 95% CI 1.14–1.41), and AIH (OR 1.13, 95% CI 1.06–1.19). Multivariable MR confirmed the causal effect of PBC and PSC on T1DM, but the link between PBC and T2DM weakened after adjusting for BMI and inflammatory bowel disease.
Conclusions
This study identifies bidirectional causal relationships between PBC/PSC and T1DM, suggesting shared pathogenesis, and T1DM also raises the risk for AIH. Although the link between PBC and T2DM weakened after adjusting for confounders, it highlights the complexity of genetic and environmental interactions, underscoring the importance of diabetes screening in AILD patients and guiding potential targeted therapies.
期刊介绍:
Journal of Diabetes Investigation is your core diabetes journal from Asia; the official journal of the Asian Association for the Study of Diabetes (AASD). The journal publishes original research, country reports, commentaries, reviews, mini-reviews, case reports, letters, as well as editorials and news. Embracing clinical and experimental research in diabetes and related areas, the Journal of Diabetes Investigation includes aspects of prevention, treatment, as well as molecular aspects and pathophysiology. Translational research focused on the exchange of ideas between clinicians and researchers is also welcome. Journal of Diabetes Investigation is indexed by Science Citation Index Expanded (SCIE).
