Brief Summary
An estimated 22% of the global population is at an increased risk of a severe form of COVID-19, while one in four coronavirus patients admitted to intensive care unit will develop a pulmonary embolism. A major public health question remains to be investigated: why COVID-19 is mild for some, critically severe for others and why only a percentage of COVID-19 patients develop thrombosis, despite the disease's proven hypercoagulable state? Patients' intrinsic characteristics might be responsible for the deep variety of disease forms. Our study aims to assess the validity of the hypothesis according to which underlining genetic variations might be responsible for different degrees of severity and thrombotic events risks in the novel coronavirus disease. Moreover, we suspect that prothrombotic genotypes occuring in the genes that encode angiotensin-converting enzyme (ACE-DEL/INS) and angiotensinogen (AGT M235T) are involved in the unpredictable evolution of COVID-19, both in terms of severity and thrombotic events, due to the strong interactions of SARS-CoV-2 with the renin-angiotensin-aldosterone system (RAAS). Therefore, we also aim to assess the validity of the theory according to which there is a pre-existing atypical modulation of RAAS in COVID-19 patients that develop severe forms and/or thrombosis. Our hypothesis is based on various observations. Firstly, there is a substantial similarity with a reasonably related condition such as sepsis, for which there is a validated theory stating that thrombophilic mutations affect patients' clinical response. Secondly, racial and ethnic genetic differences are responsible for significant dissimilar thrombotic risks among various nations. Thirdly, an increase in stroke incidence has been reported in young patients with COVID-19, without essential thrombosis risk factors, favoring the idea that a genetic predisposition could contribute to increase the thrombotic and thromboembolic risk. Fourthly, the plasminogen activator inhibitor (PAI)-1 4G/5G inherited mutation was found to be responsible for a thrombotic state causing post-SARS osteonecrosis.

One year
Secondary Outcomes (1)

One year
Study Arms (3)
COVID-19 patients with proved venous thrombosis
1st group includes COVID-19 patients with proved * venous thrombosis (deep vein thrombosis, pulmonary embolism or venous thrombosis occurring in more atypical places such as in the veins of the brain, liver, kidney, mesenteric vein and the veins of the arms) * or arterial thrombosis (heart attacks, strokes)
Asymptomatic COVID-19 & those with mild or moderate disease
2nd group encompasses asymptomatic patients and those with mild or moderate disease, according to current guidelines, without thrombosis: no symptoms or evidence of lower respiratory disease by clinical assessment or imaging and a SpO2 \> 94%
Severe disease, according to Guidelines, without thrombus
3rd group includes severe disease, according to current guidelines, without thrombosis: respiratory frequency \> 30 breaths per minute, SpO2 \< 94%, PaO2/FiO2 \< 300 mmHg, or lung infiltrates \>50%
Interventions
