Blood:APA和D-二聚体或许可作为无诱因VTE患者复发栓塞的独立的预测因子

2018-03-03 MedSci MedSci原创

目前尚不确定抗磷脂抗体(APA)是否会增加首次无诱因的静脉血栓栓塞(VTE)后再次复发的风险。现有研究人员对一前瞻性队列研究的307位首次发生无诱因VTE的患者进行两次(间隔6个月)抗磷脂抗体、抗β2糖蛋白I抗体和狼疮抗凝物检测。研究人员尝试在290位D-二聚体检测阴性而终止抗凝治疗的患者中评估APA是否与复发性血栓形成相关。与无APA的患者相比,一次或多次检测APA阳性的患者占25.9%,其VT

目前尚不确定抗磷脂抗体(APA)是否会增加首次无诱因的静脉血栓栓塞(VTE)后再次复发的风险。

现有研究人员对一前瞻性队列研究的307位首次发生无诱因VTE的患者进行两次(间隔6个月)抗磷脂抗体、抗β2糖蛋白I抗体和狼疮抗凝物检测。研究人员尝试在290位D-二聚体检测阴性而终止抗凝治疗的患者中评估APA是否与复发性血栓形成相关。与无APA的患者相比,一次或多次检测APA阳性的患者占25.9%,其VTE复发的危险比是1.8(95% CI 0.9-3.7;p=0.09),两次检测APA相同的患者占9.0%,其VTE复发的危险比是2.7(95% CI 1.1-6.7;p=0.03),一次或两次检测有两种或三种不同类型的APA的患者占3.8%,其VTE复发的危险比是4.5(95% CI 1.5-13.0;p=0.006)。APA和D-二聚体水平之间无相关性。

综上所述,两次检测到相同类型的APA或一次/多次检测出多种类型的APA,与首次发生无诱因VTE的患者在D-二聚体转阴道停止抗凝治疗后复发栓塞的风险相关。APA和D-二聚体水平似乎可作用无诱因VTE患者复发栓塞的独立的预测因子。
