摘要:


文题释义:

孟德尔随机化:是一种用于研究因果关系的方法,它通过利用遗传变异作为工具变量来评估暴露因素对特定结局的因果关系。这一方法的基本原理是,由于基因型的随机分配性质,可以将遗传变异视为自然的随机分配,从而模拟一种随机化实验。通过选择与暴露因素相关的遗传变异,可以推断出暴露因素对结局的因果性影响。
骨坏死:又被称为骨缺血性坏死或骨无菌性坏死,是一种骨骼组织疾病,通常由血液供应中断或减少引起。


背景:多项临床研究观察表明血清微量元素和营养素与骨坏死之间存在密切关系,但血清微量元素和营养素与骨坏死之间是否存在遗传因果效应尚不清楚。

目的:通过孟德尔随机化方法探讨血清微量元素与营养素对骨坏死的因果效应。
方法:暴露因素血清微量元素和维生素的单核苷酸多态性来自已发表的UK Biobank数据库以及全基因组关联研究公开数据库。结局事件骨坏死全基因组关联研究数据来自FinnGen Biobank数据库。采用孟德尔随机化方法探讨7种微量元素和3种营养素与骨坏死之间的因果关系。利用逆方差加权、MR-Egger 和加权中位数等方法进行因果推断,计算F值统计量以确保工具变量的稳健性,采用Cochran’s Q统计法和留一法进行异质性检验,采用MR-Egger回归法、MR-PRESSO进行水平多效性检验。使用PhenoScanner数据库剔除具有水平多效性的单核苷酸多态性,以确保结果的可靠性。

结果与结论:经过孟德尔随机化分析发现,血清硒、磷酸盐以及维生素C、维生素E与骨坏死之间存在明显的因果关系。血清硒、维生素C、维生素E对骨坏死有保护作用,磷酸盐摄入过多会增加骨坏死的风险。研究过程中没有发现异质性和水平多效性,孟德尔随机化统计效力(Power值> 80%)显示上述4项结果可靠,研究结果对于开发有针对性的预防及治疗骨坏死的措施具有重要临床意义。

Abstract: BACKGROUND: Multiple clinical observational studies have suggested a close relationship of serum trace elements and nutrients with osteonecrosis, but it remains unclear whether there is a genetic causal effect between serum trace elements and nutrients on osteonecrosis. 
OBJECTIVE: To investigate the causal effects of serum trace elements and nutrients on osteonecrosis using the Mendelian randomization approach. 
METHODS: The exposure factors of serum trace elements and vitamins with mononucleotide polymorphisms were obtained from the published UK Biobank database and publicly available databases of genome-wide association studies. The outcome event of osteonecrosis was derived from the FinnGen Biobank database. Mendelian randomization methods were employed to explore the causal relationship between seven trace elements and three nutrients with osteonecrosis. Causal inference was conducted using inverse variance weighting, MR-Egger, and weighted median methods. F-statistic was calculated to ensure the robustness of instrumental variables. Cochran's Q test and leave-one-out method were used for heterogeneity testing. MR-Egger regression and MR-PRESSO were employed for horizontal pleiotropy testing. PhenoScanner database was utilized to remove mononucleotide polymorphisms with horizontal pleiotropy to ensure the reliability of the results.
RESULTS AND CONCLUSION: Causal relationships were found between serum selenium, phosphate, vitamin C, vitamin E, and osteonecrosis through Mendelian randomization analysis. Serum selenium, vitamin C, and vitamin E were found to have a protective effect on osteonecrosis, while excessive intake of phosphate increased the risk of osteonecrosis. No heterogeneity or horizontal pleiotropy was observed during the study, and Mendelian randomization statistical power (Power value > 80%) indicated the reliability of the aforementioned four results. These findings have important clinical implications for the development of targeted preventive and therapeutic measures for osteonecrosis.
