Coronavirus 2019 disease (COVID-19) is associated with coagulation dysfunction that predisposes patients to an increased risk for both arterial (ATE) and venous thromboembolism (VTE) and consequent poor prognosis; in particular, the incidence of ATE and VTE in critically ill COVID-19 patients can reach 5% and 31%, respectively. The mechanism of thrombosis in COVID-19 patients is complex and still not completely clear. Recent literature suggests a link between the presence of antiphospholipid antibodies (aPLs) and thromboembolism in COVID-19 patients. However, it remains uncertain whether aPLs are an epiphenomenon or are involved in the pathogenesis of the disease.
新型冠状病毒病(COVID-19)与凝血功能障碍相关,使患者发生动脉血栓栓塞(ATE)和静脉血栓栓塞(VTE)的风险增加,并导致预后不良;特别是,危重症 COVID-19 患者的 ATE 和 VTE 发生率分别可达 5%和 31%。COVID-19 患者的血栓形成机制复杂,目前尚不完全清楚。最近的文献提示 COVID-19 患者存在抗磷脂抗体(aPLs)与血栓栓塞之间存在关联。但是,目前仍不确定 aPLs 是一种伴随现象还是参与了疾病的发病机制。
