Background. The activation of pro-coagulation mechanisms associated with the vascular wall’s immune and inflammatory responses wall to injury plays a crucial role in the mechanisms of the induction and progression of atherosclerosis.
Objectives. The aim of this study was to determine the role of protease activated receptors (PaR-1) expressed on the surface of blood platelets in the pathogenesis of chronic peripheral arterial obliterative disease (PaOd) in patients with obliterative atherosclerosis (n = 24) and diabetic macroangiopathy (n = 16), as well as in the controls (n = 12).
Material and Methods. In addition to the expression of PaR-1, serum/plasma concentrations of thrombin-antithrombin complex (TaT), the von Willebrand factor (vWf), the platelet-derived growth factor, monocyte chemotactic protein, the soluble form of the platelet endothelial cell adhesion molecule, thrombin activatable fibrinolysis inhibitor and interleukin 6 (IL-6) were determined.
Results. Compared to the controls, PaOd patients were characterized by significantly higher levels of PaR-1 expression, vWf, TaT and IL-6. Individuals with diabetic macroangiopathy did not differ significantly from individuals with obliterative atherosclerosis in terms of PaR-1 expression. Upon activation with thrombin receptor antagonist peptide (TRaP), the levels of PaR-1 were comparable in all analyzed groups. In patients with diabetic macroangiopathy, a significant association was observed between the expression of PaR-1 on the surface of the platelet and the serum TaT concentration, as well as between TaT and serum IL-6 concentration.
Conclusion. enhanced expression of PaR-1 on the thrombocyte surface in chronic PaOd patients occurs equally in cases of diabetic macroangiopathy and in individuals free from this endocrine pathology.

Key words
