RESUMEN
Introduction- Corona virus disease 2019 (COVID-19), first identified in Wuhan, China in December of 2019, has become a worldwide pandemic. It was declared by (WHO) World health organization as Public health emergency on 30th January 2020. Although respiratory compromise is the cardinal feature of the disease, early studies have suggested that elevated circulating D-dimer levels are associated with mortality, 1, 2 suggesting a distinct coagulation disorder associated with COVID-19 Materials And Methods- All patients aged ≥18 years with confirmed COVID-19 (defined as a positive SARS-CoV-2 reverse-transcriptase polymerase chain reaction test by nasopharyngeal/oropharyngeal swab or sputum specimen) were included in the study. The incidence of bleeding and thrombotic events in COVID-19 patients was assessed. Pulmonary embolism (PE) and deep vein thrombosis (DVT) were confirmed radiographically. Results of 6 routinely drawn coagulation-based laboratory parameters (PT, international normalized ratio [INR], activated partial thromboplastin time [aPTT], D-dimer, fibrinogen, and platelet count), 2 laboratory measures of inflammation (C-reactive protein [CRP], and erythrocyte sedimentation rate [ESR]), were evaluated and compared between patients with thrombotic complications (composite of venous thromboembolism, arterial thromboembolism, and clinically significant non-vessel thrombotic complications), patients with bleeding complications, and patients without bleeding or thrombotic complications. Result- In this study, we report the haemostatic manifestations and bleeding and thrombotic complications of 100 COVID-19 patients. In a population managed with standard doses of prophylactic anticoagulation, we found a radiographically confirmed venous thromboembolic rate of 4.8% (7.6% in critically ill patients) Conclusion- In conclusion, we observed that COVID-19 was associated with similar rates of thrombosis and bleeding as seen in hospitalized patients with similar degrees of critical illness. Elevated D-dimer levels at initial presentation predicted bleeding complications, thrombotic complications, critical illness, and death. Beyond D-dimer, thrombosis was primarily associated with inflammatory markers rather than coagulation parameters. We additionally found that elevations in D-dimer on admission predicted critical illness and death, as well as bleeding and thrombotic complications. Inflammatory markers, including CRP and ESR, were also associated with thrombosis.
