Brief Summary

Arterial thrombosis and unusual patterns of thrombotic events in young adults patients with COVID-19 are yet rarely described in this setting and could be underestimated. There is a real need for studies to describe the frequency of unusual thrombotic complications.

Detailed Description

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in Wuhan, China in December of 2019, has become a worldwide pandemic with widespread illness and mortality. Clinical manifestations of Coronavirus disease 2019 (COVID-19) are absent or mild in a substantial proportion of patients who test positive for COVID-19. Although respiratory compromise is the cardinal feature of the disease, early studies have suggested that elevated circulating D-dimer levels are associated with mortality suggesting a distinct coagulation disorder associated with COVID-19. COVID-19 infection is commonly complicated with pro-thrombotic state and endothelial dysfunction.

Recent autopsy studies of COVID-19 patients supported this hypothesis by demonstrating the extensive extracellular fibrin deposition and presence of fibrin thrombi within distended capillaries and small vessels. Observational studies reported an excess of venous thromboembolic events (deep vein thrombosis (DVT), pulmonary embolism (PE)) among patients suffering from Covid-19. Retrospective studies have reported thrombotic rates in excess of 20% to 30%, but the use of prophylactic anticoagulation and duration of treatment were not consistent between studies. Unrecognized PE and pulmonary in situ thrombosis were reported as causes of the high mortality observed among COVID-19 patients. There is currently no clear estimation of the risk of arterial and, in particular, venous thromboembolic complications which depend on local diagnostic and pharmacological preventive strategies. In addition to D-dimer, a prolonged prothrombin time (PT) has been associated with decreased survival and increased need for critical care.

However, arterial thrombosis and unusual patterns of thrombotic events in young adults patients with COVID-19 are yet rarely described in this setting and could be underestimated (9). Thus, there is a real need for studies to describe the frequency of unusual thrombotic complications. Therefore, the purpose of this study will be to explore thromboembolic risk and associated predicting factors in the young adults' cohort of noncritically ill COVID-19 patients which will help to optimize diagnostic, therapeutic, and preventive strategies of COVID-19 related thrombosis.

Primary Outcome Measures
NameTimeMethod
Thrombosis progressionFirst month after diagnosis

Thrombosis progression: Symptomatic extension of a pre-existing thrombus or new symptomatic thrombus not evident on the initial imaging at a second compressive examination.

MortalityFirst month after diagnosis

Bleeding complications of the UTEsFirst month after diagnosis

Bleeding (major, minor bleedings)

I. Major bleeding is defined as frank bleeding contributed to death or associated with a decreasing in hemoglobin ≥2 g/dL, or need a packed red blood cells transfusion ≥2 units, or bleeding at a critical site.

II. Non-major bleeding was defined as any symptom or sign of bleeding that did not fit the criteria of major bleeding but fulfilled at least one of the these criteria: leading to hospitalization, or requiring healthcare professional medical intervention, or spurring a face-to-face assessment.
