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,筛选与暴露因素具有强相关的遗传变异作为工具变量,排除潜在混杂因素的影响,从而更准确地推断暴露与结局之间的因果关系。
骨关节炎:是一种以关节肿胀、晨僵、慢性疼痛、活动受限为临床特征的退行性关节疾病。

背景:尽管肥胖与骨关节炎之间存在关联,但作为肥胖关键因素的内脏脂肪组织与骨关节炎之间的因果关系尚不明确。
目的:采用两样本孟德尔随机化方法探讨内脏脂肪组织与骨关节炎的因果关系。
方法:从大规模全基因组关联分析(GWAS)中筛选出221个与内脏脂肪组织强相关且无连锁不平衡的单核苷酸多态性。骨关节炎的汇总数据来自一项大型全基因组关联分析,纳入了来自9个不同人群多达826 690名受试者(177 517名骨关节炎患者和649 173名对照)。采用两样本孟德尔随机化评估内脏脂肪组织与早期任意部位骨关节炎(45岁之前)、任意部位骨关节炎、膝骨关节炎、髋骨关节炎、膝/髋骨关节炎、脊柱骨关节炎、拇指骨关节炎、手指骨关节炎之间的因果关联。以逆方差加权为主要方法进行孟德尔随机化分析,同时将加权中位数法、
MR-Egger法用于补充说明。
结果与结论:①逆方差加权分析结果显示,内脏脂肪组织对早期任意部位骨关节炎(OR=1.91,95%CI:1.64-2.24,P=6.04×10-16)、任意部位骨关节炎(OR=1.44,95%CI:1.38-1.49,P=3.65×10-75)、膝骨关节炎(OR=1.87,95%CI:1.75-2.00,P=1.29×10-79)、髋骨关节炎(OR=1.34,95%CI:1.24-1.45,P=2.84×10-14)、膝/髋骨关节炎(OR=1.71,95%CI:1.62-1.80,P=2.97×10-83)、脊柱骨关节炎(OR=1.42,95%CI:1.31-1.54,P=8.89×10-17)、拇指骨关节炎(OR=1.26,95%CI:1.10-1.44,P=6.21×10-4)、手指骨关节炎(OR=1.29,95%CI:1.13-1.49,P=2.68×10-4)具有正向因果效应;②敏感性分析结果显示,内脏脂肪组织对8种骨关节炎的因果效应没有异质性、多效性或异常值;③结果提示内脏脂肪组织是骨关节炎的风险因素,过多的内脏脂肪组织可能会增加患骨关节炎的风险。

Abstract: BACKGROUND: Although obesity is associated with osteoarthritis, it remains unclear whether visceral adipose tissue has a causal relationship with osteoarthritis. 
OBJECTIVE: To investigate the causal relationship between visceral adipose tissue and osteoarthritis using two-sample Mendelian randomization methods. 
METHODS: A total of 221 single nucleotide polymorphisms strongly associated with visceral adipose tissue without linkage disequilibrium were screened from the genome-wide association study (GWAS). Pooled data for osteoarthritis were derived from a large genome-wide association analysis that included up to 826 690 subjects (177 517 osteoarthritis patients and 649 173 controls) from nine different populations. We conducted two-sample Mendelian randomization analyses to assess the causal associations between visceral adipose tissue and early-onset any-site osteoarthritis (before age 45), any-site osteoarthritis, knee osteoarthritis, hip osteoarthritis, knee or hip osteoarthritis, spinal osteoarthritis, thumb osteoarthritis, and finger osteoarthritis. Inverse variance weighting was employed as the primary Mendelian randomization analysis method, with weighted median and MR-Egger methods used for supplementary clarification. 
RESULTS AND CONCLUSION: Inverse variance weighting results revealed a positive causal effect of visceral adipose tissue on eight types of osteoarthritis: early-onset any-site osteoarthritis [odds ratio (OR)=1.91, 95% confidence interval (CI): 1.64-2.24, P=6.04×10-16], any-site osteoarthritis (OR=1.44, 95% CI: 1.38-1.49, P=3.65×10-75), knee osteoarthritis (OR=1.87, 95% CI: 1.75-2.00, P=1.29×10-79), hip osteoarthritis (OR=1.34, 95% CI: 1.24-1.45, P=2.84×10-14), knee or hip osteoarthritis (OR=1.71, 95% CI: 1.62-1.80, P=2.97×10-83), spinal osteoarthritis (OR=1.42, 95% CI: 1.31-1.54, P=8.89×10-17), thumb osteoarthritis (OR=1.26, 95% CI: 1.10-1.44, P=6.21×10-4), and finger osteoarthritis (OR=1.29, 95% CI: 1.13-1.49, P=2.68×10-4). Sensitivity analyses showed no heterogeneity, pleiotropy, or outliers in the causal effects of visceral adipose tissue on the eight types of osteoarthritis. These findings indicate that visceral adipose tissue is a risk factor of osteoarthritis, and excessive visceral adipose tissue may increase the risk of osteoarthritis.
