Popis: Background and objectives: Cushing’s syndrome (CS) is associated with an increased cardiovascular mortality and morbidity. Chronic endogenous and exogenous hypercortisolism frequently induce a hypercoagulable and thrombotic condition. Little is known about hemostatic features of patients with CS. To our knowledge, plasma tissue factor pathway inhibitor (TFPI) and thrombin-activatable fibrinolysis inhibitor (TAFI) levels in these patients have not been investigated. Therefore, the main purpose of this study was to evaluate the markers of endogenous coagulation/fibrinolysis, including TFPI and TAFI, and to investigate the relationships between cortisol and these hemostatic parameters and serum lipid profile in patients with CS. Design and methods: Twenty-four patients with CS and 24 age-matched healthy controls were included in the study. Prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, factors V, VII, VIII, IX, and X activities, von Willebrand factor (vWF), antithrombin III (AT III), protein C, protein S, tissue plasminogen activator (t-PA), tissue plasminogen activator inhibitor-1 (PAI-1), TFPI and TAFI, as well as common lipid variables, were measured. The relationships between serum cortisol and these hemostatic parameters were examined. Results: Compared with the control subjects, platelet count, PT, fibrinogen, AT-III and PAI-1 were significantly increased in patients with CS (p
