J Thromb Haemost:高风险抗磷脂综合征患者血小板减少症!

2018-01-09 xing.T MedSci原创

该研究结果显示高危APS患者血小板减少症患病率较低。在所有恶化为灾难性疾病的患者中均可观察到血小板计数下降。高危APS患者血小板计数下降应被视为疾病进展至CAPS的警示信号。

血小板减少症是抗磷脂综合征(APS)患者最常见的非标准性血液学特征。这种疾病在严重APS(CAPS)中更常见。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,研究人员评估了一系列APS高危患者血小板减少症的患病率,并且评估CAPS患者血小板计数的情况。

这是一项横断面研究,研究人员分析了同组高危APS患者(三联症阳性)的血小板计数。其中6名患者发展为疾病的灾难性阶段,并在发病前、急性期和恢复期记录了血小板计数。

119名高危三联症阳性患者平均血小板计数为210×109/L。考虑到血小板减少症的临界值为100×109/L,血小板减少症的患病率为6%(7例患者)。研究人员发现主要APS和次要APS之间没有差异。在CAPS患者中,血小板计数从基础(212×109/L±51)到诊断时(60×109/L±33)显著下降。完全缓解时血小板计数恢复正常(220×109/L±57)。血小板计数下降总是先于整个临床情况变化。

该研究结果显示高危APS患者血小板减少症患病率较低。在所有恶化为灾难性疾病的患者中均可观察到血小板计数下降。高危APS患者血小板计数下降应被视为疾病进展至CAPS的警示信号。
