We present a putative link between maternal COVID-19 infection in the peripartum period and rapid maternal deterioration with early organ dysfunction and coagulopathy. The current pandemic with SARS-CoV-2 has already resulted in high numbers of critically ill patients and deaths in the non-pregnant population, mainly due to respiratory failure. During viral outbreaks, pregnancy poses a uniquely increased risk to women due to changes to immune function, alongside physiological adaptive alterations, such as increased oxygen consumption and edema of the respiratory tract. The laboratory derangements may be reminiscent of HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome, and thus knowledge of the COVID-19 relationship is paramount for appropriate diagnosis and management. In addition to routine measurements of D-dimers, prothrombin time, and platelet count in all patients presenting with COVID-19 as per International Society on Thrombosis and Haemostasis (ISTH) guidance, monitoring of activated partial thromboplastin time (APTT) and fibrinogen levels should be considered in pregnancy, as highlighted in this report. These investigations in SARS-CoV-2-positive pregnant women are vital, as their derangement may signal a more severe COVID-19 infection, and may warrant pre-emptive admission and consideration of delivery to achieve maternal stabilization.
我们提出了母体在围产期感染 COVID-19 与早期器官功能障碍和凝血功能障碍的快速母体恶化之间的假定联系。当前由 SARS-CoV-2 引起的大流行已经在非孕妇人群中导致了大量重症患者和死亡,主要是由于呼吸衰竭。在病毒爆发期间,由于免疫功能的改变以及生理适应性改变,例如耗氧量增加和呼吸道水肿,妊娠会给妇女带来独特的更高风险。实验室异常可能与 HELLP(溶血、肝酶升高、血小板计数低)综合征相似,因此了解 COVID-19 的关系对于进行适当的诊断和管理至关重要。除了按照国际血栓形成和止血学会 (ISTH) 的指南对所有出现 COVID-19 的患者进行常规的 D-二聚体、凝血酶原时间和血小板计数测量外,本报告强调,在妊娠期间还应考虑监测活化部分凝血活酶时间 (APTT) 和纤维蛋白原水平。对 SARS-CoV-2 阳性孕妇进行这些检查至关重要,因为它们的异常可能表明 COVID-19 感染更严重,可能需要提前入院并考虑分娩以实现母体稳定。
