摘要:

文题释义

孟德尔随机化:是一种利用自然遗传变异来模拟随机对照试验的方法,该方法基于全基因组关联研究,使用遗传变异作为工具变量,以推断可改变的暴露与疾病之间的因果关系。
肌肉骨骼疾病:包括一系列身体肌肉、骨骼、韧带及关节损伤的疾病,这些疾病可能导致骨骼系统的结构、功能或代谢的异常,引起一系列症状,包括但不限于疼痛、运动障碍、变形等。

摘要
背景:多项观察性研究表明,端粒长度与肌肉骨骼疾病之间存在潜在的关联,然而它们之间的潜在机制仍不清楚。
目的:利用两样本孟德尔随机化分析来探索端粒长度与肌肉骨骼疾病之间的遗传因果关系。
方法:从英国生物银行中获得端粒长度的全基因组关联研究汇总数据。从FinnGen财团中获得了关于10种常见肌肉骨骼疾病(骨坏死、骨髓炎、骨质疏松、类风湿关节炎、腰痛、椎管狭窄、痛风、肩周炎、强直性脊柱炎和下肢深静脉血栓)的全基因组关联研究汇总数据。使用逆方差加权、孟德尔随机化-Egger和加权中位数方法评估端粒长度与10种肌肉骨骼疾病的因果关系,逆方差加权作为主要的孟德尔随机化分析方法,并进行敏感性分析探讨结果稳健性。
结果与结论:①逆方差加权法结果表明,遗传预测的端粒长度与类风湿关节炎(OR=0.78,95%CI:0.64-0.95,P=0.015)和骨坏死(OR=0.56,95%CI:0.36-0.90,P=0.016)风险之间存在负向因果关系,但未发现端粒长度与其他8种肌肉骨骼疾病之间存在因果关系(P均 > 0.05)。②敏感性分析结果表明因果关系稳健,孟德尔随机化-Egger截距分析未检测到潜在的水平多效性(P均 > 0.05)。③此项孟德尔随机化研究支持端粒长度对类风湿关节炎和骨坏死的保护作用的结论,然而,未来将需要更多的基础和临床研究来验证。

Abstract: BACKGROUND: Multiple observational studies have suggested a potential association between telomere length and musculoskeletal diseases. However, the underlying mechanisms remain unclear. 
OBJECTIVE: To investigate the genetic causal relationship between telomere length and musculoskeletal diseases using two-sample Mendelian randomization analysis. 
METHODS: Genome-wide association study summary data of telomere length were obtained from the UK Biobank. Genome-wide association study summary data of 10 common musculoskeletal diseases (osteonecrosis, osteomyelitis, osteoporosis, rheumatoid arthritis, low back pain, spinal stenosis, gout, scapulohumeral periarthritis, ankylosing spondylitis and deep venous thrombosis of lower limbs) were obtained from the FinnGen consortium. Inverse variance weighting, Mendelian randomization-Egger and weighted median methods were used to evaluate the causal relationship between telomere length and 10 musculoskeletal diseases. Inverse variance weighting was the primary Mendelian randomization analysis method, and sensitivity analysis was performed to explore the robustness of the results.
RESULTS AND CONCLUSION: (1) Inverse variance-weighted results indicated a negative causal relationship between genetically predicted telomere length and rheumatoid arthritis (odds ratio=0.78, 95% confidence interval: 0.64-0.95, P=0.015) and osteonecrosis (odds ratio=0.56, 95% confidence interval: 0.36-0.90, P=0.016). No causal relationship was found between telomere length and the other eight musculoskeletal diseases (all P > 0.05). (2) Sensitivity analysis affirmed the robustness of these causal relationships, and Mendelian randomization-Egger intercept analysis found no evidence of potential horizontal pleiotropy (all P > 0.05). (3) This Mendelian randomized study supports that telomere length has protective effects against rheumatoid arthritis and osteonecrosis. However, more basic and clinical research will be needed to support our findings in the future.
