Stroke:中性粒细胞胞外陷阱标志物循环DNA与癌症相关卒中

2019-08-11 xing.T MedSci原创

由此可见,循环DNA水平升高与癌症相关的卒中相关,表明NET是癌症相关卒中的分子机制之一。需要在大型队列中进行进一步的长期随访研究,以确认NET特异性生物标志物的作用。

循环中性粒细胞胞外陷阱(NETs)对癌症相关卒中的作用尚不清楚。近日,心血管疾病领域权威杂志Stroke上发表了一篇研究文章,研究人员进行了一项前瞻性队列研究,以评估NETs在癌症相关卒中中是否增加以及NETs水平升高是否与使用D-二聚体水平(≥2μg/ mL)进行衡量的凝血功能障碍相关。

研究人员将血浆DNA和核小体作为评估NET的特异性生物标志物,总共招募了138名患者; 38名患者患有癌症相关性卒中(活动性癌症和急性隐源性栓塞性卒中),33名患者为健康对照者,27名患者为癌症对照者(活动性癌症但无卒中),40名患者为卒中对照者(急性缺血性卒中但没有癌症)。

癌症相关卒中患者的血浆DNA和核小体水平显著高于健康对照者(P<0.05)。血浆DNA和核小体水平与D-二聚体水平相关(P<0.01)。在多元回归分析中,调整可能的混杂因素后,血浆DNA水平升高(最高四分位数的比值比=11.65; 95%CI为3.199-42.46)和D-二聚体水平≥2μg/mL(最高四分位数比值比=19.09 ; 95%CI为4.143-87.95)与癌症相关的卒中相关。 

由此可见,循环DNA水平升高与癌症相关的卒中相关,表明NET是癌症相关卒中的分子机制之一。需要在大型队列中进行进一步的长期随访研究,以确认NET特异性生物标志物的作用。
