There are 5 clinical trials
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.
Description: the cumulative proportion of any distal or proximal deep venous thrombosis or of symptomatic pulmonary embolism
Measure: the cumulative proportion of any distal or proximal deep venous thrombosis or of symptomatic pulmonary embolism Time: 28 daysDescription: the cumulative proportion of any distal or proximal deep venous thrombosis or of symptomatic pulmonary embolism plus the asymptomatic incidentally detected pulmonary embolism
Measure: the cumulative proportion of any distal or proximal deep venous thrombosis or of symptomatic pulmonary embolism plus the asymptomatic incidentally detected pulmonary embolism Time: 28 daysWorldwide 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.
Description: Risk of deep vein thrombosis or pulmonary embolism or venous thromboembolism-related death
Measure: Venous thromboembolism Time: 28 daysDescription: Risk of major bleeding defined by the ISTH
Measure: Major bleeding Time: 28 daysDescription: Risk of Major Bleeding and Clinically Relevant Non-Major Bleeding Defined by the ISTH
Measure: Major Bleeding and Clinically Relevant Non-Major Bleeding Time: 28 daysDescription: Risk of Venous Thromboembolism and Major Bleeding
Measure: Net Clinical Benefit Time: 28 days and 2 monthsDescription: Risk of venous thrombosis at other sites: e.g. superficial vein, catheters, hemodialysis access, ECMO, splanchnic, encephalic, upper limb
Measure: Venous Thromboembolism at other sites Time: 28 daysDescription: Risk of arterial thrombosis at any sites
Measure: Arterial Thrombosis Time: 28 daysDescription: Risk of all-cause mortality
Measure: All-Cause Mortality Time: 28 days and 2 monthsDescription: Identification of associations between the risk of venous thromboembolism and clinical (eg. past medical history of thrombosis, cardiovascular risk factors, treatments, severity of COVID-19) and laboratory variables (e.g. D-dimers, fibrinogen, CRP) collected in the eCRF
Measure: Factors associated with the risk of venous thromboembolism Time: 28 daysSevere COVID-19 patients at a high risk of venous thromboembolism. We studied patients in 2 intensive care units of university hospitals in Barcelona and Badalona, Spain. We performed a cut-off screening of deep venous thrombosis (DVT) with bilateral duplex ultrasound to 230 patients.
Description: Patients with symptomatic pulmonary embolism confirmed on the CT-angiography and those with a swollen limb and confirmed deep venous thrombosis on compression ultrasound were considered to have "symptomatic venous thromboembolisms". The remaining patients with positive limb ultrasound or CT-angiography were considered to have "asymptomatic venous thrombembolism"
Measure: Venous thromboembolisms Time: 7 daysDescription: Deaths from all causes during the follow-up
Measure: Deaths Time: 7 daysThe 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.
This is a multicenter, open-label, 2x2 factorial, randomized-controlled trial in critically-ill patients with novel coronavirus disease 2019 (COVID-19) evaluating the efficacy and safety of full-dose vs. standard prophylactic dose anticoagulation and of antiplatelet vs. no antiplatelet therapy for prevention of venous and arterial thrombotic events.
Description: Hierarchical composite: Death due to venous or arterial thrombosis, pulmonary embolism, clinically evident DVT, type 1 MI, ischemic stroke, systemic embolism or acute limb ischemia, or clinically silent DVT
Measure: Primary endpoint: Venous or arterial thrombotic events Time: 28 days or until hospital discharge, whichever earlierDescription: Hierarchical composite: Death due to venous or arterial thrombosis, pulmonary embolism, clinically evident DVT, type 1 MI, ischemic stroke, systemic embolism or acute limb ischemia
Measure: Key secondary endpoint: Clinically evident venous or arterial thrombotic events Time: 28 days or until hospital discharge, whichever earlier
