Stroke:糖尿病患者血清神经丝轻链水平与卒中

2019-05-29 xing.T 网络

由此可见,血清NfL水平可预测卒中事件并显著增加Framingham卒中风险评分在中老年糖尿病患者中的区分能力。

有效的卒中预防取决于准确的卒中风险预测。近日,血管疾病领域权威杂志Stroke上发表了一篇研究文章,研究人员旨在确定神经丝轻链(NfL)水平在7年随访期间用于区分发生和未发生卒中的糖尿病患者的辨别能力。

研究人员从先前完成ACCORD试验(控制血管风险因素行动糖尿病)中选择参与者进行了病例对照研究。病例均为ACCORD受试者,他们在入组时无卒中,并在随访期间发生卒中(n=113)。对照受试者(n=250)为随机选择的在随机化前或后没有发生卒中事件的ACCORD参与者。研究人员使用单分子阵列技术(Quanterix)测量了基线样品中NfL水平。

在调整年龄、种族、血压、体重和Framingham卒中风险评分后,与对照组相比,卒中受试者的基线NfL水平更高。在调整种族和Framingham卒中风险评分后,相对于NfL水平最低五分位数的受试者,第2至第5五分位数受试者的卒中发生率分别为3.91(1.45-10.53)、4.05(1.52-10.79)、5.63(2.16-14.66)和9.75 (3.84-27.71)。将NfL水平纳入已包括种族和Framingham卒中风险评分的预测评分中,其将评分的C统计量从0.71(95%CI为0.66-0.77)增加至0.78(95%CI为0.73-0.83),P <0.001。年龄较大,非白人种族,收缩压较高,肾小球滤过率<60,血红蛋白A1C较高是该队列血清NfL的独立预测因子,但舒张压、高血压糖尿病持续时间以及血脂水平均未降低。总体而言,心血管疾病风险因素解释了基线NfL水平变异性的19.2%。 

由此可见,血清NfL水平可预测卒中事件并显著增加Framingham卒中风险评分在中老年糖尿病患者中的区分能力。
