Abstract:
Disseminated intravascular coagulation (DIC) is an acquired syndrome that can lead to catastrophic thrombosis and hemorrhage. In DIC, an uncontrolled release of pro-inflammatory mediators activates tissue factor-dependent coagulation. These changes cause endothelial dysfunction and increased depletion of platelets and clotting factors needed to control bleeding, which results in excessive bleeding. The clinical manifestations are microvascular thrombosis and hemorrhage, which cause severe organ dysfunction and worsening of organ failure. Its clinical management is challenging. Coronavirus disease 2019 (COVID-19) is characterized mainly by respiratory manifestations. In severe cases, however, systemic inflammatory response syndrome can develop with cytokine release that leads to coagulopathy and DIC. Among patients with COVID-19, this complication occurs rarely, leading to death in the majority of cases. We describe the case of a 67-year-old woman with asthma and class 1 obesity, hospitalized with respiratory insufficiency after diagnosis of COVID-19, in whom DIC developed with hemorrhagic manifestations on Day 4 of hospitalization. In spite of poor prognosis and multiple complications throughout the 87 days of hospitalization, including 62 days in the ICU, this patient survived.

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
