Gout and Rheumatoid arthritis (RA) are two prevalent non-infectious inflammatory joint diseases that can occur independently or concurrently. The effects and mechanisms related to antibody-mediated immune responses and both Gout and RA remain unclear. The research seeks to investigate the potential causal association and offer a novel perspective for their prevention and treatment strategies.
The study employed the bidirectional two-sample Mendelian randomization (MR) analysis for investigation. Datasets comprising 46 antibody-mediated immune responses, as well as those for Gout and RA, were curated from published genome-wide association studies (GWAS). For the causality analysis, methods such as Inverse Variance Weighted (IVW), Weighted Median, Simple Mode, MR-Egger, and Weighted Mode were utilized. We chose MR pleiotropy residual sum and outlier (MR-PRESSO), IVW, MR-Egger, and Leave-one-out for sensitivity analysis to enhance the reliability of the results.
We meticulously excluded the results that exhibited pleiotropy and instability. Finally, four antibody-mediated immune responses have been found as causal factors in the development of Gout: Anti-chlamydia trachomatis IgG seropositivity, Anti-human herpes virus 6 IE1B IgG seropositivity, Helicobacter pylori GroEL antibody levels, and Polyomavirus 2 JC VP1 antibody levels; Two antibody-mediated immune responses influence RA causally: BK polyomavirus VP1 antibody levels, and Helicobacter pylori Catalase antibody levels. In the reverse analysis, three antibody-mediated immune responses could be influenced by Gout: BK polyomavirus VP1 antibody levels, Chlamydia trachomatis tarp-D F2 antibody levels, and Varicella zoster virus glycoproteins E and I antibody levels; Two antibody-mediated immune responses could be causally affected by RA: Anti-human herpes virus 7 IgG seropositivity, and Merkel cell polyomavirus VP1 antibody levels.
The research indicated that antibody-mediated immune responses establish a causal link with this two non-infectious inflammatory joint diseases: Gout and RA, offering new avenues and perspectives for the future prophylaxis and treatment of diseases from an immunological standpoint.
痛风和类风湿关节炎(RA)是两种常见的非感染性炎性关节疾病,可单独或同时发生。与抗体介导的免疫反应以及痛风和RA相关的影响和机制仍不清楚。本研究旨在调查潜在的因果关联,并为其预防和治疗策略提供新的视角。
本研究采用双向两样本孟德尔随机化(MR)分析进行调查。从已发表的全基因组关联研究(GWAS)中整理出包含46种抗体介导的免疫反应以及痛风和RA的数据集。在因果关系分析中,使用了逆方差加权(IVW)、加权中位数、简单模式、MR-Egger和加权模式等方法。我们选择MR多效性残差和异常值(MR-PRESSO)、IVW、MR-Egger和留一法进行敏感性分析,以提高结果的可靠性。
我们精心排除了表现出多效性和不稳定性的结果。最终,发现四种抗体介导的免疫反应是痛风发生的因果因素:抗沙眼衣原体IgG血清阳性、抗人疱疹病毒6 IE1B IgG血清阳性、幽门螺杆菌GroEL抗体水平和多瘤病毒2 JC VP1抗体水平;两种抗体介导的免疫反应对RA有因果影响:BK多瘤病毒VP1抗体水平和幽门螺杆菌过氧化氢酶抗体水平。在反向分析中,三种抗体介导的免疫反应可能受痛风影响:BK多瘤病毒VP1抗体水平、沙眼衣原体tarp-D F2抗体水平和水痘带状疱疹病毒糖蛋白E和I抗体水平;两种抗体介导的免疫反应可能受RA因果影响:抗人疱疹病毒7 IgG血清阳性和默克尔细胞多瘤病毒VP1抗体水平。
该研究表明,抗体介导的免疫反应与这两种非感染性炎性关节疾病——痛风和RA建立了因果联系,从免疫学角度为未来疾病的预防和治疗提供了新的途径和视角。
