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).

Intervention Details:
  • Other: Observational study
    Coagulation factors, Hypercoagulation biomarkers, Endothelial, Fibrinolysis and neutrophil activation biomarkers


Primary Outcome Measures :
  1. Incidence of mortality among enrolled COVID-19 patients [ Time Frame: 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.

  2. Incidence of thrombosis among enrolled COVID patients [ Time Frame: 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 :
  1. Evaluation the role of enoxaparin in the management of Covid-19-associated coagulopathy [ Time Frame: 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


Biospecimen Retention:   Samples Without DNA
Blood samples for hemostasis study are collected from all study subjects at admission. After discarding the first 2-3 mL of blood, peripheral venous blood samples were collected into 6 mL vacuum tubes (BD, Vacutainer ™, Plymouth, UK) containing 3.2% citrate (0.109 mol/L, 1:9 vol./vol.) for coagulation studies, and K3-ethylenediamine tetraacetic acid (K3-EDTA) 7.2mg for the complete blood cell count study.

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
