摘要:

目的 探讨脂蛋白相关磷脂酶A2(Lp-PLA2)联合MRI总负荷评分对脑小血管病(CSVD)患者认知障碍的预测价值。方法 纳入178例CSVD患者并根据蒙特利尔认知评估量表(MoCA)将其分为认知正常组(MoCA≥26分)89例和认知障碍组(MoCA<26分)89例,采用3.0 T MRI评价CSVD影像学总负荷评分。比较2组患者基线资料、Lp-PLA2水平、MRI总负荷,Logistic回归分析CSVD患者认知障碍的影响因素,受试者工作特征(ROC)曲线评估Lp-PLA2水平联合MRI总负荷评分对CSVD患者认知障碍的预测价值。结果 与认知正常组相比,认知障碍组Lp-PLA2水平、MRI总负荷评分、白细胞介素(IL)-6水平均升高(P<0.05),多因素Logistic回归分析结果显示,Lp-PLA2水平、MRI总负荷升高为CSVD患者认知障碍的危险因素(P<0.05),ROC曲线分析结果显示,Lp-PLA2水平联合MRI总负荷评分预测CSVD患者认知障碍的曲线下面积为0.905(95%CI:0.861~0.948),敏感度为86.5%,特异度为79.8%。结论 认知障碍患者的Lp-PLA2水平、MRI总负荷评分升高,两者联合可作为CSVD患者认知障碍的早期预测指标。

Abstract:

Objective To investigate the predictive value of lipoprotein-associated phospholipase A2 (Lp-PLA2) combined with the total burden of magnetic resonance imaging (MRI) scores on cognitive impairment in patients with cerebral small vessel disease (CSVD). Methods A total of 178 CSVD patients admitted to Gansu Wuwei Tumour Hospital (Gansu Province Wuwei Academy of Medical Sciences) from January 2023 to June 2024 were divided into the normal cognition group (n= 89, MoCA≥26) and the cognitive impairment group (n=89, MoCA<26 points). The CSVD total burden of MRI scores was evaluated by 3.0T MRI. The baseline data, Lp-PLA2 level and the total burden of MRI scores were compared between the two groups. Logistic regression was applied to analyze influencing factors of cognitive impairment in CSVD patients. The predictive value of Lp-PLA2 level combined with the total burden of MRI scores on cognitive impairment in CSVD patients were analyzed by receiver operating characteristic (ROC) curve. Results Compared with the normal cognition group, Lp-PLA2 levels, the total burden of MRI scores and IL-6 were significantly increased in the cognitive impairment group (P<0.05). Results of multivariate Logistic regression analysis showed that increased Lp-PLA2 and the total burden of MRI scores were risk factors for cognitive impairment in patients with CSVD (P<0.05). The area under curve (AUC) of Lp-PLA2 levels combined with the total burden of MRI scores for predicting cognitive impairment in patients with CSVD was 0.905 (95%CI:0.861-0.948), the sensitivity was 86.5% and the specificity was 79.8%. Conclusion Lp-PLA2 levels and the total burden of MRI scores are increased in patients with cognitive impairment, and the combination of both can serve as an early predictor of cognitive impairment in patients with CSVD.
