SARS-CoV-2 infection is associated with hypercoagulability which predisposes to venous thromboembolism (VTE). We analyzed platelet and neutrophil activation in COVID-19 patients and their association with VTE. Methods Hospitalized COVID-19 patients and age- and sex-matched healthy controls were studied. Platelet and leukocyte activation, neutrophil extracellular traps (NETs), and matrix metalloproteinase-9 (MMP-9), a neutrophil-released enzyme, were measured. Four patients were re-studied after recovery. The activating effect of … Continue reading #Neutrophil more than #platelet activation associates with #thrombotic complications in #COVID-19 patients
