摘要:


文题释义:
免疫细胞:是指参与机体免疫反应或与免疫相关的细胞,如淋巴细胞、巨噬细胞等,它们能够识别和抵御病原体,维护机体的免疫平衡与健康。
代谢性骨病:是指由于机体代谢紊乱(包括激素、维生素、矿物质等代谢异常)导致骨组织的代谢障碍而引发的一类骨疾病。代谢性骨病的发病机制复杂,常见的病因包括内分泌失调、营养缺乏、免疫因素等。

背景:免疫细胞与多种代谢性骨病具有相关性,但具体的免疫学机制和因果关系尚不明确。
目的:运用两样本孟德尔随机化方法探讨免疫细胞与代谢性骨病风险的因果关系。
方法:从公开数据库中获取731种免疫细胞、代谢性骨病(骨坏死、骨软化症、骨质疏松、骨质疏松合并病理性骨折)的GWAS数据,使用免疫细胞的遗传变异作为工具变量。将逆方差加权法作为主分析方法,同时采用MR-Egger和加权中位数法评价免疫细胞与代谢性骨病风险的因果关系。运用MR-PRESSO、MR-Egger回归、Cochran’s Q检验和留一法评价工具变量的基因多态性、异质性,并运用MR Steiger法排除反向因果关系。
结果与结论:①IgD- CD38dim%B细胞、HLA DR on CD14+ CD16-单核细胞、HLA DR on CD14+单核细胞与骨质疏松风险增加存在显著因果关系
(P < 6.8×10-5),并且敏感性分析显示结果可靠,具有稳定性。此外,共发现28种免疫细胞与骨坏死、23种免疫细胞与骨软化症、46种免疫细胞与骨质疏松、45种免疫细胞与骨质疏松合并病理性骨折具有潜在因果关系(P < 0.05)。②该研究全面评估免疫细胞对代谢性骨病因果影响,阐释免疫因素在骨质疏松为代表的代谢性骨病发病机制中的重要作用,为深入认识免疫性状与骨代谢的关系提供参考。该研究采用国际数据库对欧洲群体进行分析,为中国生物医学在代谢性骨病领域的研究提供借鉴,有助于开展针对中国人群的相关研究,促进代谢性骨病防治水平的提升。

Abstract: BACKGROUND: Immune cells are correlated with various metabolic bone diseases, yet the specific immunological mechanisms and causal relationships remain elusive.
OBJECTIVE: To investigate the causal relationship between immune cells and the risk of metabolic bone diseases through two-sample Mendelian randomization. 
METHODS: Genome-wide association study (GWAS) data on 731 immune cells and metabolic bone diseases (osteonecrosis, osteomalacia, osteoporosis, and osteoporosis combined with pathological fracture) were obtained from publicly available databases. Genetic variants related to immune cells were employed as instrumental variables. The inverse variance weighting method was utilized as the primary analytical approach, while MR-Egger and weighted median methods were applied to assess the causal relationships between immune cells and the risk of metabolic bone diseases. In addition, MR-PRESSO, MR-Egger regression, Cochran’s Q test, and the leave-one-out method were implemented to evaluate genetic polymorphisms and the heterogeneity of instrumental variables, and MR Steiger method was used to exclude reverse causality.
RESULTS AND CONCLUSION: (1) The analysis revealed that IgD- CD38dim%B cells, HLA DR on CD14+ CD16- monocytes, and HLA DR on CD14+ monocytes were significantly and causally associated with an increased risk of osteoporosis (P < 6.8×10-5). Sensitivity analyses confirmed the reliability and stability of these results. Furthermore, among the immune cell types studied, 28 demonstrated potential causal associations with osteonecrosis, 23 with osteomalacia, 46 with osteoporosis, and 45 with the combined condition of osteoporosis and pathologic fracture (P < 0.05). (2) This study provides a comprehensive assessment of the causal influence of immune cells on metabolic bone diseases, highlighting the significant role of immune factors in the pathogenesis of these conditions, particularly osteoporosis. The findings contribute valuable insights into the relationship between immune traits and bone metabolism, laying a foundation for future research in this domain. This study utilized an international database to analyze the European population, which offers a reference for Chinese biomedical research in the realm of metabolic bone diseases, and facilitates the conduction of relevant studies for the Chinese population, thereby promoting the enhancement of the prevention and treatment of metabolic bone diseases.
