Neurology:自发性脑动脉夹层患者血浆原纤维蛋白-1水平的价值!

2018-02-01 xing.T MedSci原创

由此可见,血浆原纤维蛋白-1是诊断急性sCeAD的良好生物标志物,并对病变严重程度分级和影像学预后判断具有潜在价值。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,该研究旨在探讨血浆原纤维蛋白-1水平在自发性脑动脉夹层(sCeAD)患者中的价值。

该单中心前瞻性队列研究在2013年2月至2015年12月期间纳入了99例连续就诊的sCeAD患者,以及年龄和性别匹配115例非sCeAD缺血性卒中患者和20例经常规体格检查证实的健康参与者。研究人员采用ELISA检测了受试者血浆中原纤蛋白-1水平,并在3组间进行比较。研究人员分析了原纤维蛋白-1与sCeAD部位、敏锐度和解剖严重程度以及患者的临床和影像学预后之间的相关性。

研究人员从99例sCeAD患者中收集了109份血浆标本,从疾病对照患者中收集了115份标本和从健康对照者收集了20份血浆标本。sCeAD组受试者血浆原纤维蛋白-1水平(平均85.56ng/mL[95%可信区间为81.53-89.59])显著高于非sCeAD缺血性卒中组受试者(77.13ng/mL[73.64-80.63],P=0.015)或健康对照者(73.04ng/mL[65.94-80.13],P=0.029)。这种差异在急性期最为突出(分别为97.64ng/mL[91.64-103.64]、74.39ng/mL [68.95-79.84]和73.04ng/mL[65.95-80.13])。确定临界值为88.455ng/mL,以区分急性夹层和非夹层性卒中,敏感性为0.778,特异性为0.800。解剖影像学检查结果更严重的受试者具有较高的原纤维蛋白-1水平(P<0.001),而基线时原纤维蛋白-1浓度较低的患者在随访影像学检查中获得了更好的形态学恢复(P=0.003)。

由此可见,血浆原纤维蛋白-1是诊断急性sCeAD的良好生物标志物,并对病变严重程度分级和影像学预后判断具有潜在价值。
