摘要:


文题释义:
孟德尔随机化:是一种基于遗传变异的因果推断方法。它利用基因变异作为工具变量,这些基因变异在人群中随机分配,不受环境和生活方式等混杂因素的影响。通过孟德尔随机化方法,研究者可以推断生物学因素对疾病的影响,为医学研究和公共卫生政策的制定提供重要依据。在甲状腺功能和骨质疏松症的研究中,孟德尔随机化方法被用来探究遗传预测的甲状腺功能及其相关疾病与骨质疏松症的潜在因果联系。
中介分析:在孟德尔随机化的基础上,进一步探究生物学暴露因素通过中介变量对疾病结局的间接影响。在甲状腺功能和骨质疏松症的研究中,中介分析被用来揭示治疗药物(如卡比马唑和左旋甲状腺素钠)在甲状腺功能障碍与骨质疏松症发病风险之间的因果关系中的潜在中介效应。通过中介分析,研究者可以更准确地了解疾病的发生机制,并为制定针对性的防治策略提供依据。

背景:多项观察性研究发现甲状腺功能及其相关疾病与骨质疏松症之间存在密切关系,但其因果关系尚不明确。
目的:通过大型汇总遗传数据,采用孟德尔随机化分析来探究遗传预测的甲状腺功能及其相关疾病与骨质疏松症的因果关系。
方法:使用全基因组关联研究汇总数据,以逆方差加权法为主要的孟德尔随机化分析方法,同时采用MR-Egger法、加权中位数法、简单模式法和加权模式法,分析甲状腺功能及其相关疾病与骨质疏松症之间的因果关系;并采用两步法中介孟德尔随机化分析,计算药物介导的甲状腺功能障碍对骨质疏松的中介效应及中介比例,最后进行敏感性分析,使用MR-Egger截距测试和MR-PRESSO检测多效性,Cochran’s Q检验检测异质性,留一法进行敏感性分析。
结果与结论:①逆方差加权法结果显示甲状腺功能对骨密度可产生影响,促甲状腺素、游离三碘甲状腺原氨酸对骨密度、游离甲状腺素、亚临床甲状腺功能亢进症均与骨密度存在因果效应;②此外,中介分析显示卡比马唑在甲状腺功能亢进症与骨质疏松症发病风险之间的因果关系中存在潜在中介效应;左旋甲状腺素钠在甲状腺功能减退症与骨质疏松症发病风险之间的因果关系中存在潜在中介效应;③综上,正常范围内偏高的促甲状腺素能够增加骨密度,而正常范围内偏高的游离三碘甲状腺原氨酸和游离甲状腺素以及亚临床甲状腺功能亢进症会降低骨密度,并且在甲状腺功能障碍药物治疗时,其骨质疏松症发病风险一定程度上是通过服用治疗药物这一中介路径介导的;④此次研究主要聚焦于欧洲人群数据,但鉴于遗传背景的共通性及全基因组数据分析方法的普适性,其对探索中国人群骨质疏松症的发病机制、制定有效干预措施及遗传咨询等方面具有重要的参考和借鉴意义。

Abstract: BACKGROUND: Several observational studies have found a strong association between thyroid function and its related disorders and osteoporosis, but the causal relationship is unclear.
OBJECTIVE: To ascertain the causal relationship between genetically predicted thyroid function and its associated disorders, as well as osteoporosis, through the Mendelian randomization analysis with extensive pooled genetic data.
METHODS: Pooled data from genome-wide association studies were employed to investigate the causal relationship between thyroid function and its associated disorders and osteoporosis. This was achieved through the utilization of the inverse variance weighting method as the primary Mendelian randomization analysis method, in conjunction with the MR-Egger method, weighted median method, simple model method, and weighted model method. A two-step mediated Mendelian randomization analysis was used to calculate the mediating effect of drug-mediated thyroid dysfunction on osteoporosis and the mediating proportion. Subsequently, sensitivity analyses were conducted using the MR-Egger intercept test and MR-PRESSO to detect multiplicity, Cochran’s Q test to detect heterogeneity, and leave-one-out to perform sensitivity analyses.
RESULTS AND CONCLUSION: (1) The results of the inverse variance weighting method showed that thyroid function had an effect on bone mineral density, and that thyrotropin, free triiodothyronine on bone mineral density, free thyroxine, and subclinical hyperthyroidism all had a causal effect on bone mineral density. (2) In addition, mediation analyses revealed a potential mediating effect of carbimazole in the causal relationship between hyperthyroidism and the risk of developing osteoporosis, as well as a potential mediating effect of levothyroxine sodium in the causal relationship between hypothyroidism and the risk of developing osteoporosis. (3) In conclusion, thyrotropin, which is high in the normal range, has been demonstrated to increase bone mineral density. Conversely, free triiodothyronine and free thyroxine, which are also high within the normal range, as well as subclinical hyperthyroidism, have been shown to decrease bone mineral density. The risk of developing osteoporosis is partially mediated by the pathway of taking the therapeutic medication in the context of pharmacologic treatment of thyroid dysfunction. (4) The present study primarily focuses on European population data. However, given the commonality of the genetic background and the generalizability of genome-wide data analysis methods, it is of significant importance to explore the pathogenesis of osteoporosis in the Chinese population, develop effective interventions, and provide genetic counseling.
