[Thrombin activatable fibrinolysis o inhibitor-TAFI- in dialyzed patients with diabetic nephropathy].

Patients with end-stage renal disease dialyzed due to diabetic nephropathy are at higher risk of death due to cardiovascular complications than dialyzed non-diabetic patients. Disturbances in hemostasis may play a role in the vascular complications of diabetes mellitus. It has been postulated that TAFI-Thrombin Activatable Fibrinolysis Inhibitor, newly described glycoprotein, couples two opposite systems: coagulation and fibrinolysis. The aim of the work was to study TAFI concentration in hemodialyzed and peritoneally dialyzed diabetic and non-diabetic patients. We assessed: TAFI concentration, markers of ongoing coagulation: thrombin-antithrombin complexes, prothrombin fragments 1 + 2 (markers of TAFI activation), a marker of ongoing fibrinolysis: plasmin-antiplasmin complexes, a marker of TAFI cataliser to TAFIa-thrombomodulin using commercially available kits. All four groups studied did not differ in regard to fibrinogen, thrombomodulin, plasmin-antiplasmin complexes, and TAFI concentration. Both groups of dialyzed diabetic patients have higher concentration of markers of ongoing coagulation when compared to dialyzed non-diabetic patients. Hypercoagulable state observed in dialyzed diabetic patients may contribute to the higher cardiovascular mortality in these population.
