Causal relationship between primary biliary cholangitis on osteoporosis: A two-sample Mendelian randomization study

Year: 2025

Type: article

Abstract: This present study aims to investigate the relationship between primary biliary cholangitis (PBC) and osteoporosis (OP) using a two-sample Mendelian randomization (MR) analysis. A two-sample MR study was conducted to explore the association between PBC and OP. The inverse variance weighted test was primarily used to estimate causality. Horizontal pleiotropy was assessed using both MR-PRESSO and MR-Egger regression techniques. Cochran Q test was applied to examine heterogeneity among single nucleotide polymorphisms (SNPs), and a sensitivity analysis was performed to evaluate the impact of each individual SNP on the MR analysis results. The two-sample MR analysis result showed a significant association between PBC and OP, with an inverse variance weighted odds ratio of 1.098 (95% confidence interval: 1.049-1.150,and a P = 5.41e-05). MR-Egger regression indicated no bias due to genetic pleiotropy (intercept = 0.007, SE = 0.022, P = .754). Cochran Q test revealed no significant heterogeneity (Q = 27.494, P = .236). Furthermore, leave-one-out analysis confirmed the robustness of our findings, as the results remained consistent even when individual SNPs were excluded. This study provides evidence supporting the notion that PBC may increase the risk of OP, enhancing our understanding of the association between PBC and OP.
