Activities of protein C, free-protein S and antithrombin, activated protein C resistance, levels of fibrinogen. D-dimer, thrombin-antithrombin complex (TAT), prothrombin fragments 1+2 (PF1+2), and von Willebrand factor antigen (vWAg) and its activity (RiCof) were investigated in acute and recovery phases of HSP and controls. Fibrinogen, D-dimer, TAT, PF1+2, vWAg, and RiCof levels in patients with HSP during the acute phase were significantly higher than those of recovery phase and of the controls. A significant correlation was detected between severity of disease and TAT, PF1+2, vWAg, and D-dimer levels.en10.1080/08880010590896251info:eu-repo/semantics/closedAccessChildHenoch-Schönlein purpuraHypercoagulabilityArticle221414815770830Q3
