Abstract

肝素(UFH)诱导的血小板减少症(HIT)是一种严重的免疫介导性药物不良反应,其根源在于机体暴露于肝素环境后引起血小板活化,从而促进血小板α-颗粒释放血小板第4因子(PF4)。活化的血小板、内皮细胞、单核细胞及中性粒细胞共同诱发机体血小板减少和血栓形成。本文综述了UFH诱导的HIT发病机制及治疗的最新研究现状与进展。首先,研究发现PF4/UFH超大型复合物(ULCs)通过与IgM结合激活信号通路等方式促使机体产生特异性IgG抗体。其次,超大型IgG抗体复合物(PF4-H-IgG)与血小板、单核细胞、中性粒细胞结合并诱导凝血酶的生成。再次,预测FcγRⅡa受体本身及其细胞活化介质、内皮细胞、PAR-1受体可能成为未来新干预措施的靶点。最后,在目前治疗HIT患者常规替代抗凝方案之外,核酸适配体和脂肪氧化酶抑制剂有望成为新的HIT潜在替代治疗药物。本综述有助于提高HIT的临床诊治水平。.
