摘要:


文题释义:

膝骨关节炎:是一种慢性膝关节退行性疾病,好发于中老年人。该病病理特征是关节软骨的慢性磨损。在临床上,膝骨关节炎表现为渐进性的关节疼痛、僵硬、肿胀、活动受限和畸形。
孟德尔随机化:是一种新型的研究方法,使用遗传变异作为工具变量,评估暴露因素与结局之间的因果关系。这种方法利用在受孕时自然发生的等位基因随机分配进行因果推断。特定暴露水平通常独立于其他暴露因素,不受疾病状况的影响。因此,孟德尔随机化研究能够克服观察性研究中残留混杂和反向因果关系的限制。


背景:近年来,流行病学研究显示睡眠特征是骨关节炎的危险因素,但睡眠特征与骨关节炎之间是否存在因果关联仍未知。

目的:探讨7种睡眠表型与骨关节炎的因果关系,以期为临床防治提供理论依据。
方法:从已发表的全基因组关联研究中选择了7个与睡眠相关的特征:睡眠持续时间、早上起床、白天小睡、早起/晚起类型、打鼾、失眠和嗜睡症,提取这些睡眠相关特征的工具变量。膝骨关节炎和髋骨关节炎的工具变量来自公开全基因组关联研究。通过双样本和多变量孟德尔随机化分析,以评估睡眠特征与结局风险的因果关系。采用逆方差加权法作为主要孟德尔随机化分析方法,采用加权中位数、加权模式、孟德尔随机化-Egger回归、孟德尔随机化多效性残差和异常值等方法检测和校正多效性的存在。

结果与结论:①两样本孟德尔随机化的逆方差加权法结果显示,睡眠时间与膝骨关节炎发病风险呈负向因果关联(OR=0.621,95%CI:0.470-0.822,P=0.001),失眠与髋骨关节炎发病风险呈正向因果关联(OR=2.016,95%CI:1.249-3.254,P=0.005)。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(膝骨关节炎:P=0.468,髋骨关节炎:P=0.551)。②多变量孟德尔随机化结果显示,失眠与髋骨关节炎的因果关联没有统计学意义(P=0.715),睡眠时间对膝骨关节炎发病风险有直接的负向因果关联(OR=0.526,95%CI:0.336-0.824,P=0.005)。反向孟德尔随机化结果显示,膝骨关节炎不是睡眠时间的影响因素(P=0.757)。③睡眠时间与膝骨关节炎发病风险呈负相关,纠正短睡眠时间可能减轻膝骨关节炎发病风险。

Abstract: BACKGROUND: In recent years, epidemiological studies have shown that sleep patterns are risk factors for osteoarthritis, but the causal relationship between sleep characteristics and osteoarthritis remains unknown.
OBJECTIVE: To investigate the causal relationship between seven sleep phenotypes and osteoarthritis, thereby providing a theoretical foundation for clinical prevention and intervention of osteoarthritis. 
METHODS: Seven sleep-related features, namely sleep duration, wake-up time, daytime napping, morning/evening preference, snoring, insomnia, and hypersomnia, were selected from published genome-wide association studies. Instrumental variables for these sleep-related features were extracted. Instrumental variables for knee osteoarthritis and hip osteoarthritis were obtained from publicly available genome-wide association studies. Causal relationships between sleep characteristics and outcome risks were evaluated using two-sample and multivariable Mendelian randomization analyses. The inverse variance weighted method was employed as the primary Mendelian randomization approach. Various methods, including weighted median, weighted mode, Mendelian randomization-Egger regression, Mendelian randomization pleiotropy-residual sum and outlier, were utilized to detect and correct for the presence of pleiotropy.
RESULTS AND CONCLUSION: The results of the inverse variance-weighted method in the two-sample Mendelian randomization study revealed a detrimental causal association between the duration of sleep and the incidence risk of knee osteoarthritis [odds ratio (OR)=0.621, 95% confidence interval (CI): 0.470-0.822, P=0.001]. Concurrently, insomnia displayed a positive causal connection with hip osteoarthritis risk (OR=2.016, 95% CI: 1.249-3.254, P=0.005). Sensitivity analysis affirmed the robustness of these causal relationships, and Mendelian randomization-Egger intercept analysis found no evidence of potential horizontal pleiotropy (knee osteoarthritis: P=0.468, hip osteoarthritis: P=0.551). Moreover, the results from the multivariable Mendelian randomization analysis showed that the causal association between insomnia and hip osteoarthritis lacked statistical significance (P=0.715). In contrast, sleep duration exhibited a direct negative causal relationship with the incidence risk of knee osteoarthritis (OR=0.526, 95% CI: 0.336-0.824, P=0.005). Reverse Mendelian randomization analysis indicated that knee osteoarthritis did not influence sleep duration (P=0.757). These findings indicate a negative correlation between sleep duration and incidence risk of knee osteoarthritis, suggesting that correcting insufficient sleep might mitigate the incidence risk of knee osteoarthritis.

Key words: sleeplessness, sleep duration, knee osteoarthritis, Mendelian randomization study, causal association
