摘要

Patients with novel coronavirus pneumonia show increased thrombotic risk. Although hemostatic alterations have been described in novel coronavirus pneumonia patients, case–control studies of von Willebrand factor (VWF), factor VIII (FVIII), and a disintegrin-like and metalloprotease with thrombospondin type I motif, member 13 (ADAMTS13) are lacking. VWF, ADAMTS13, FVIII, d -dimer, C-reactive protein, and routine blood cells and chemistry were measured in 10 novel coronavirus pneumonia patients and 10 non-novel coronavirus pneumonia controls. Hemostatic factors were measured less than 48?h of hospital admission in patients without invasive ventilation. d -Dimer, C-reactive protein, and fibrinogen concentrations, high in both groups, did not differ significantly in novel coronavirus pneumonia vs. non-novel coronavirus pneumonia patients. Median VWF-antigen (324 vs. 153?IU/dl, P ?
