1 Dynamics of Hemostatic Parameters in COVID-19 and Comparison of Intervention Strategies Through Adaptive Clinical Trial

Hypercoagulability has been demonstrated in COVID-19, leading to respiratory distress and increased mortality. This is adaptive clinical trial to compare effectiveness and safety of four therapeutic strategies in hospital mortality in patients with COVID-19: standard prophylaxis, therapeutic dose anticoagulation, inhaled UFH associated with standard prophylaxis and ASA associated with standard prophylaxis.

2 CoV-Hep Study: Randomized and Paired Clinical Trial Comparing Regional Anticoagulation Modalities in Continuous Venous Venous Hemodialysis in Patients With COVID-19

Since the emergence of the new strain of betacoronavirus (SARS-CoV-2) and its important clinical repercussions, it has been described that patients with its associated pneumonia (COVID-19) have high rates of thrombotic events, including reduction in the dialyzers patency when undergoing renal replacement therapy. Several strategies for preventing the early loss of dialysers are described, and regional anticoagulation based on citrate is the preferred modality for preventing this complication. On the other hand, in patients with SARS-CoV-2 there are already descriptions of endothelial inflammation and activation of the coagulation cascade, including studies demonstrating the benefit of heparinization of these patients. Thus, this study aims to compare two different anticoagulation strategies in patients infected with COVID-19 with continued venovenous hemodialysis (CVVHD). From the indication of CVVHD, patients will be screened according to eligibility criteria and, if they fit these parameters, they will be randomized into two groups: Group A - Standard regional anticoagulation based on Citrate associated with infusion of low doses of unfractionated heparin 10ui/kg/hour and Group B - Standard regional anticoagulation based on Citrate only. Patients will be randomized in blocks and followed for 72 hours. The primary endpoint is dialyzer patency at the end of 72 hours of clinical follow-up. Secondary objectives will be mortality, bleeding rate, drop in hematimetric indices, urea sieving, filter time in hours, down time of therapy, system and dialyser pressures (PBE and PTM). All patients will undergo a standard procedure with a prescribed dose of 30mL/Kg/H, blood flow of 150mL/minute and polysulfone dialyzer.
