EMO-COVID: Hemostatic Profile in Patients Affected by COVID-19
Study Details
Study Description
Brief Summary
Coronavirus disease-2019 (COVID-19), a viral respiratory illness caused by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has been associated with the occurrence of cardiovascular adverse events including acute myocardial injury, acute heart failure, cardiac arrhythmias, and thromboembolic disease. These complications represent an important issue in COVID-19 patients accounting for the increased morbidity and mortality of this syndrome. According to a scoping review, venous thromboembolism and stroke occurred in approximately 20% and 3% of patients, respectively, with higher frequency observed in severely ill patients admitted to intensive care units. Despite the use of pharmacological thromboprophylaxis, the thrombotic risk still remained elevated in severe COVID-19 patients, and the optimal doses and timing of anticoagulation are not yet defined. The pathogenesis of COVID-19 associated thrombosis recognizes a prominent role of endothelial damage induced by both direct viral injury and an excessive and aberrant hyper-inflammatory host immune response associated to an increase in infection-related cytokines and chemokines. The occurrence of a hypercoagulable state in COVID-19 patients associated to a profound endothelial cell activation/dysfunction can result in the pathological phenomenon of immunothrombosis.
In this study, in a prospective cohort of consecutive COVID-19 hospitalized patients, an extensive characterization of the hemostatic alterations were performed, in order to: 1) clarify mechanisms underlying the coagulopathy in these patients; 2) how and to what extent the concomitant infection with SARS-CoV-2 affect this coagulopathy; and 3) identify biomarkers potentially predictive of disease outcome (i.e. any thrombotic recurrence and death).

Outcome Measures
Primary Outcome Measures
- Incidence of mortality among enrolled COVID-19 patients [up to 6 months from the date of the enrollment]
Identification of variables for prediction of mortality derived from review of clinical records. Samples collected from identified participants with COVID19 diagnosis will be assessed to determine thrombotic and inflammatory biomarkers able to prediction of mortality.
- Incidence of thrombosis among enrolled COVID patients [up to 12 months from the date of the enrollment]
Identification of COVID-19 patients with evidence of thrombotic event derived from review of clinical records. Samples collected from identified participants with COVID19 diagnosis will be assessed to determine thrombotic and inflammatory biomarkers.
Secondary Outcome Measures
- Evaluation the role of enoxaparin in the management of Covid-19-associated coagulopathy [Samples collected from identified participants with COVID19 diagnosis will be assessed to determine the effect of thromboprophylaxis on thrombotic and inflammatory biomarkers]
up to 12 months from the date of the enrollment
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Age> 18 years
-
Adult patients admitted with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) positivity (by real time-PCR) from nasal swab or deep respiratory specimen or with clinical signs suggestive of SARS-Cov-2
-
Patients who have signed informed consent. If there is no possibility of obtaining informed consent for the clinical picture (eg adult patients sedated and curarized for acute respiratory failure and consequent mechanical ventilation), the patient's consent will be assumed until the contrary will be manifested.
