[Plasminogen activators (t-PA and u-PA) and other fibrinolysis parameters in patients with atherosclerosis obliterans and diabetic macroangiopathy].

UNLABELLED

The aim of the study was to evaluate plasminogen activators in compare fibrinolysis parameters in patients with atherosclerosis obliterans (AO) and diabetic macroangiopathy (DM) of lover extremities. The study group consist of 40 patients with AO (mean age 59 years) and 40 with DM (mean age 61 years). All the patients were diagnosed as the II stage in Fontaine scale. Ischemia lover extremities were: aorta-hip, femoral-popliteal and peripheral dependent closure. The control group consist of 30 healthy volunteers (mean age 51 years). Concentration of: tissue plasminogen activator antigen (t-PA:Ag), urokinase plasminogen activator antigen (u-PA:Ag), plasminogen activator inhibitor type 1 antigen (PAI-1:Ag) (ELISA), PAI-1 activity (PAI-1 act.), euglobulin lysis time (ELT) (Kowarzyk-Buluk method), fibrinogen, fibrin degradation products (FDP) (Merskey method) in blood plasma were evaluated. The results shows statistically higher concentrations of: t-PA:Ag, PAI-1:Ag, fibrinogen, and lower concentrations of u-PA:Ag and elongated ELT in blood plasma patients with AO and DM in compare with healthy volunteers. Comparing analysed parameters between patient groups shows higher concentration FDP in patients with AO than patients with DM.

CONCLUSIONS

1. Although elongated ELT in both groups it was shown evidence of the fibrinolysis activation in the shape of elevated FDP concentration. It was probably compensation for hypercoagulability. 2) Elevated t-PA:Ag concentration in patients with AO and DM is an evidence of the higher releasing of the endothelium in AO and DM.
