J Thromb Haemost:年龄调整后的D-二聚体临界值对静脉血栓栓塞诊断更有效!

2018-03-06 xing.T MedSci原创

由此可见,年龄调整后临界值仍然可以保持较高的灵敏度,特异性适当改善。假阳性结果明显减少,这反映了避免了不必要的影像学检查。这表明年龄调整后临界值对于老年患者静脉血栓栓塞的治疗在临床和经济上都有好处。

近日,血栓和凝血疾病权威杂志Journal of Thrombosis and Haemostasis上发表了一篇研究文章,该研究旨在比较疑似静脉血栓栓塞(VTE)的门诊患者不同的二聚体检测及年龄调整的临界值价值。这种敏感的生物标志物的血浆浓度随凝血功能激活而增加,但也与一些VTE风险增加的情况相关。老年就是一种这样的情况,老年是一个常见的临床问题,许多人不愿意为老年患者检测D-二聚体水平。年龄调整后的临界值已被深静脉血栓形成(DVT)和肺栓塞所证实,以增加其特异性,而无显著降低灵敏度。研究人员评估了四种常见的D-二聚体检测方法,并比较了运用和未运用年龄调整后的临界值来评估VTE。

该前瞻性单中心研究是在940名门诊病人中进行的。研究人员比较了四种自动的D-二聚体检测手段(西门子INNOVANCE®、Roche Tina-quant、medirox MRX和STA®-Liatest® D-Di PLUS)。

所有实验ROC曲线(AUC)下面积>0.9,年龄调整临界值实施后仍可维持其敏感性。特异性增加6-7%,试验所需数量减少<0.3。假阳性结局发生率整体下降了6%,在≥70岁的患者种降低了10-20%。

由此可见,年龄调整后临界值仍然可以保持较高的灵敏度,特异性适当改善。假阳性结果明显减少,这反映了避免了不必要的影像学检查。这表明年龄调整后临界值对于老年患者静脉血栓栓塞的治疗在临床和经济上都有好处。
