Heparin-induced thrombocytopenia (HIT) is a profoundly dangerous, potentially lethal, immunologically mediated adverse drug reaction to unfractionated heparin or, less commonly, to low-molecular weight heparin. Some patients with HIT develop serious thrombotic complications like limb ischemia and gangrene, while others may not develop such complications. Current laboratory diagnostic tools incur significant time delays before confirming HIT, therefore upon clinical suspicion, treatment of HIT should start immediately. In this review, the authors highlight heparin-induced thrombocytopenias risk factors, clinical presentation, pathophysiology, diagnostic principles, and treatment.
肝素诱导的血小板减少症(HIT)是一种极其危险、可能致命的、由免疫介导的针对普通肝素或较少见的低分子肝素的药物不良反应。一些HIT患者会出现严重的血栓形成并发症,如肢体缺血和坏疽,而另一些患者可能不会出现此类并发症。目前的实验室诊断工具在确诊HIT之前会导致显著的时间延迟,因此一旦临床怀疑,应立即开始HIT的治疗。在这篇综述中,作者强调了肝素诱导的血小板减少症的危险因素、临床表现、病理生理学、诊断原则和治疗方法。
