ABSTRACT
BACKGROUND:
Coronavirus Disease 2019 (COVID-19) is associated with Coagulopathy (CAC) and Venous Thromboembolism (VTE). These are well-reported complications of COVID-19 infection. Earlier publications have shown that CAC and thromboembolism are predictors of mortality among COVID-19 patients with severe disease. MATERIALS ANDMETHODS:
A prospective study was conducted in the Intensive Care Unit (ICU) where all confirmed COVID-19 patients were enrolled and followed until death or ICU discharge. CAC, VTE, along with all comorbidities, were recorded. Predictors of mortality were determined by univariate and multivariate regression.RESULTS:
Among 261 patients with COVID-19, 48.3% survived and 51.7% died. CAC was present in 53.2% and 76.3% of the survivors and non-survivors, respectively (p<0.001); 89 patients (31.4%) had VTE (p=0.36) and 11 patients (4.2%) had arterial thrombosis (p=0.76) among survivors and nonsurvivors. Age between 71-80 years (p=0.009), male gender (p=0.045), CAC (p<0.001), comorbidities like chronic kidney disease (CKD, p=0.013), chronic obstructive pulmonary disease (COPD, p=0.001) and asthma (p=0.046), were significant predictors of mortality.CONCLUSION:
A severe complication of COVID-19 is CAC, such as sepsis-induced coagulopathy, overt disseminated-coagulopathy and VTE. Old age, various comorbidities (e.g., COPD, CKD, or asthma), CAC, VTE (pulmonary embolism) and coagulation parameters with critical severity score (D-dimers, platelets, prothrombin time) and the SOFA (Sequential Organ Failure Assessment) score were significant predictors of mortality among COVID-19 patients.Keywords
