This illustrated review discusses the haemostatic changes seen in patients with severe coronavirus disease 2019 (COVID-19) infection and their possible causes. We discuss the crosstalk between inflammation and coagulation resulting in high levels of acute-phase proteins, very high levels of D-dimers, and absence of disseminated intravascular coagulation seen in patients with severe COVID-19. There appear to be high rates of venous thromboembolism and also, what has been poorly described before in acute lung injury, a high rate of pulmonary immunothrombosis (thrombosis secondary to inflammation).
本图文综述讨论了2019年冠状病毒病(COVID-19)重症患者出现的止血变化及其可能原因。我们探讨了炎症与凝血之间的相互作用,这种相互作用导致重症COVID-19患者出现高水平的急性期蛋白、极高水平的D-二聚体,以及无弥散性血管内凝血。重症COVID-19患者似乎有较高的静脉血栓栓塞发生率,而且在急性肺损伤中之前描述较少的是,有较高的肺免疫血栓形成发生率(炎症继发的血栓形成)。
