OBJECTIVES
Knee osteoarthritis (KOA) and certain inflammatory cytokines (such as interleukin 1 [IL-1] and tumor necrosis factor alpha [TNF-a]) are related; however, the causal relationship remains unclear. Here, we aimed to assess the causal relationship between 41 inflammatory cytokines and KOA using Mendelian randomization (MR).
METHODS
Two-sample bidirectional MR was performed using genetic variation data for 41 inflammatory cytokines that were obtained from European Genome-Wide Association Study (GWAS) data (n=8293). KOA-related genetic association data were also obtained from European GWAS data (n=40,3124). Inverse variance weighting (IVW), MR, heterogeneity, sensitivity, and multiple validation analyses were performed.
RESULTS
Granulocyte colony-stimulating factor (G-CSF) or colony-stimulating factor 3 (CSF-3) levels were negatively associated with the risk of developing KOA (OR: 0.93, 95%CI:0.89-0.99, =0.015). Additionally, macrophage inflammatory protein-1 alpha (MIP-1A/CCL3) was a consequence of KOA (OR: 0.72, 95%CI:0.54-0.97, =0.032). No causal relationship was evident between other inflammatory cytokines and KOA development.
CONCLUSION
This study suggests that certain inflammatory cytokines may be associated with KOA etiology. G-CSF exerts an upstream influence on KOA development, whereas MIP-1A (CCL-3) acts as a downstream factor.
目的
膝关节骨关节炎(KOA)与某些炎性细胞因子(如白细胞介素1 [IL-1]和肿瘤坏死因子α [TNF-α])相关;然而,因果关系仍不明确。在此,我们旨在使用孟德尔随机化(MR)评估41种炎性细胞因子与KOA之间的因果关系。
方法
使用从欧洲全基因组关联研究(GWAS)数据(n = 8293)中获得的41种炎性细胞因子的基因变异数据进行两样本双向MR。KOA相关的基因关联数据也从欧洲GWAS数据(n = 403124)中获得。进行了逆方差加权(IVW)、MR、异质性、敏感性和多重验证分析。
结果
粒细胞集落刺激因子(G-CSF)或集落刺激因子3(CSF-3)水平与发生KOA的风险呈负相关(OR:0.93,95%CI:0.89 - 0.99,P = 0.015)。此外,巨噬细胞炎性蛋白-1α(MIP-1A/CCL3)是KOA的一个结果(OR:0.72,95%CI:0.54 - 0.97,P = 0.032)。其他炎性细胞因子与KOA发展之间未发现明显的因果关系。
结论
本研究表明某些炎性细胞因子可能与KOA病因相关。G-CSF对KOA发展具有上游影响,而MIP-1A(CCL-3)作为下游因子起作用。
