1 Increased Risk of Venous Thromboembolism and Higher Hypercoagulable State in Patients Recovered in Intensive Care Unit and in Medical Ward for Coronavirus Disease 2019 (COVID-19)

The aim of this study is to verify if patients admitted to hospital in a medical division and in the intensive care unit for a COVID-19 infection are at higher risk of developing a VTE complication and if they actually present an increased hypercoagulable state.

2 Effectiveness of Weight-adjusted Prophylactic Low Molecular Weight Heparin Doses Compared With Lower Fixed Prophylactic Doses to Prevent Venous Thromboembolism in COVID-2019. The Multicenter Randomized Controlled Open-label Trial COVI-DOSE

Worldwide observational studies indicate a significant prothrombogenic effect associated with SARS-CoV-2 infection with a high incidence of venous thromboembolism (VTE), notably life-threatening pulmonary embolism. According to recommendations for acute medical illnesses, all COVID-19 hospitalized patients should be given VTE prophylaxis such as a low molecular weight heparin (LMWH). A standard prophylactic dose (eg. Enoxaparin 4000IU once daily) could be insufficient in obese patients and VTE has been reported in patients treated with a standard prophylactic dose. In COVID-19 patients, guidelines from several international societies confirm the existence of an hypercoagulability and the importance of thromboprophylaxis but the "optimal dose is unknown" and comparative studies are needed. In view of these elements, carrying out a trial comparing various therapeutic strategies for the prevention of VTE in hospitalized patients with COVID-19 constitutes a health emergency. Thus, we hypothesize that an increased prophylactic dose of weight-adjusted LMWH would be greater than a lower prophylactic dose of LMWH to reduce the risk of life-threatening VTE in hospitalized patients. The benefit-risk balance of this increase dose will be carefully evaluated because of bleeding complications favored by possible renal / hepatic dysfunctions, drug interactions or invasive procedures in COVID-19 patients. This multicenter randomized (1:1) open-label controlled trial will randomize hospitalized adults with COVID-19 infection to weight-adjusted prophylactic dose vs. lower prophylactic dose of LMWH.

4 Prevalence and Severity of Venous Thromboembolism in a General Population During the COVID-19 Pandemic

The purpose of this study is to investigate the prevalence of venous thromboembolism in a regional health care system (Region Östergötland, Sweden) before and during the SARS-COV-2 pandemic. In a retrospective observational study, we will review patient data, diagnostic data and treatment data over a three-month period since the onset of the SARS-COV-2 pandemic. This data will be compared with data from the corresponding time frame during the years 2015 to 2019.
