Abstract
Background: Coronavirus disease 2019 (COVID-19) has spread globally. However, the association between COVID-19 and disseminated intravascular coagulation (DIC) has been scarcely addressed. We aimed to systematically characterize the clinical features and examine risk factors for DIC development in COVID-19 patients. Methods: In this single-centered, retrospective, and observational study, all patients with DIC (N=59) and 270 patients without DIC were matched by propensity score matching based on age, sex, and comorbidities. Demographic data, symptoms, radiological, laboratory examinations, and clinical outcomes were compared between patients with and without DIC. Furthermore, univariable and multivariable logistic regression were used to explore the risk factors associated with DIC development in COVID-19 patients. Findings: Higher proportion of patients with DIC and COVID-19 (54 of 59 [91·53%]) developed into death than non DIC patients (58 of 270 [21·48%]). Patients with DIC presented aggravated inflammation responses, liver damage, and especially coagulation dysfunction. Moreover, in addition to previously reported coagulation-related markers, such as FDP, D-dimer, and platelet, we also identified several novel risk factors associated with DIC development, including decreased fibrinogen (OR=0·476, 95%CI=0·380-0·596, P Interpretation: Patients with DIC and COVID-19 were predisposed to poor clinical outcomes. These risk factors identified may be helpful for early surveillance of disease progression and making standardized treatment strategies.
