Neurology:NfL是帕金森病严重程度和进展的生物标志物

2019-08-17 xing.T MedSci原创

由此可见,血浆NfL水平与PD患者运动和认知功能的疾病严重程度和进展相关。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,该研究旨在评估血浆神经丝轻链(NfL)水平是否与帕金森病(PD)患者的运动和认知进展相关。

这项前瞻性随访研究纳入了178名参与者,其中116名参与者患有PD,22名参与者患有多系统萎缩(MSA),40名为健康对照者。研究人员采用电化学发光免疫测定法测量血浆NfL水平。PD患者在基线和3年平均随访间隔时接受运动和认知评估。研究人员采用统一帕金森病评定量表(UPDRS)第III部分运动评分和简易精神状态检查评分的变化来评估运动和认知进展。

MSA组血浆NfL水平显著高于PD组和健康组(分别为35.8±6.2、17.6±2.8和10.6±2.3 pg/mL,p<0.001)。在PD组中,Hoehn-Yahr分期为晚期并有痴呆的患者NfL水平显著升高(p<0.001)。NfL水平与UPDRS第III部分评分适度相关(r=0.42,95%置信区间为0.46-0.56,p<0.001)。在平均随访3.3±1.2年后,针对年龄、性别、疾病持续时间和基线运动或认知状态调整的Cox回归分析显示较高的基线NfL水平与运动或认知进展的较高风险相关(分别有p=0.029和p=0.015)。

由此可见,血浆NfL水平与PD患者运动和认知功能的疾病严重程度和进展相关。
