摘要

目的·通过两样本孟德尔随机化（Mendelian randomization，MR）方法探讨乳糜泻（celiac disease，CeD）与桥本甲状腺炎（Hashimoto thyroiditis，HT）及格雷夫斯病（Graves disease，GD）之间的双向因果关系。方法·从公开的全基因组关联研究（Genome-Wide Association Studies，GWAS）数据库中提取与CeD、HT和GD相关的单核苷酸多态性（single nucleotide polymorphism，SNP）数据，作为工具变量。以逆方差加权法（inverse variance weighted，IVW）作为主要分析方法，同时将MR-Egger法、加权中位数法（weighted median，WME）、加权模式法（weighted mode，WMO）3种方法的结果作为参考，评估CeD与HT及GD之间的因果关联。使用不同的GWAS数据进行重复分析，验证结果的稳健性。通过Cochran's Q检验判断异质性，通过MR-Egger截距检验评估多效性，采用留一法（leave-one-out）分析单个SNP对结果的影响程度。结果·IVW分析结果表明，遗传预测的CeD显著增加HT［试验组：OR=1.186 （95%CI 1.114~1.262），P<0.001；验证组：OR=1.218（95%CI 1.090~1.361），P<0.001］和GD［试验组：OR=1.214 （95%CI 1.155~1.276），P<0.001；验证组：OR=1.273（95%CI 1.161~1.396），P<0.001］的风险。反向MR分析中，HT对CeD不存在因果关系，而遗传预测的GD则显著增加CeD［试验组：OR=1.259（95%CI 1.006~1.576），P=0.044；验证组：OR=1.387（95%CI 1.233~1.560），P<0.001］的风险。敏感性分析表明，结果未受水平多效性的影响。结论·CeD可能增加HT和GD的发病风险，而GD可能增加CeD的发病风险，但HT对CeD不存在影响。

Abstract

Objective ·To investigate the bidirectional causal relationships between celiac disease (CeD) and Hashimoto thyroiditis (HT) as well as Graves disease (GD), using a two-sample Mendelian randomization (MR) approach. Methods ·Single nucleotide polymorphisms (SNPs) related to CeD, HT and GD were extracted from publicly available Genome-Wide Association Studies (GWAS) databases and used as instrumental variables. The inverse-variance weighted (IVW) method served as the primary analytical approach, supplemented by MR-Egger, weighted median (WME) and weighted mode (WMO) methods, to evaluate the causal associations between CeD and both HT and GD. Replication analyses using alternative GWAS datasets were conducted to validate the robustness of the results. Heterogeneity was assessed using Cochran's Q test, and pleiotropy was evaluated via MR-Egger intercept test. Leave-one-out analyses were performed to assess the impact of individual SNPs on the results. Results ·The IVW analysis results indicated that genetically predicted CeD significantly increased the risk of HT [discovery group: OR=1.186 (95%CI 1.114‒1.262), P<0.001; replication group: OR=1.218 (95%CI 1.090‒1.361), P<0.001] and GD [discovery group: OR=1.214 (95%CI 1.155‒1.276), P<0.001; replication group: OR=1.273 (95%CI 1.161‒1.396), P<0.001]. However, reverse MR analyses did not provide evidence for a causal relationship between HT and CeD, while genetically predicted GD significantly increased the risk of CeD [discovery group: OR=1.259 (95%CI 1.006‒1.576), P=0.044; replication group: OR=1.387 (95%CI 1.233‒1.560), P<0.001]. Sensitivity analyses suggested that the results were not influenced by horizontal pleiotropy. Conclusion ·CeD may be causally associated with a higher risk of HT and GD, while GD may increase the risk of developing CeD. HT does not appear to have an impact on CeD.
