    Abstract:
    To investigate the relationship between changes in plasma concentrations of polymorphonuclear elastase (PMN-E) and haemostatic effects during haemodialysis (HD), changes in the plasma concentrations of elastase-alpha 1 proteinase inhibitor complex (E-alpha 1 PI) and fibrinogen (Fbg), cross-linked fibrin degradation products (XDP), thrombin-antithrombin III complex (TAT), plasmin-alpha 2 plasmin inhibitor complex (PIC) and soluble thrombomodulin (TM) in 49 patients with end-stage chronic glomerulonephritis maintained on chronic HD were measured. Plasma concentrations of TAT, PIC, TM and E-alpha 1 PI significantly increased during a single HD. There was a statistically significant correlation between change in plasma E-alpha 1 PI concentration and changes in plasma concentrations of TAT, PIC and TM during a single HD, as well as between changes in plasma concentrations of TM and TAT during a single HD. These observations suggested that activation of coagulation and fibrinolysis, endothelial cell damage, and activation of polymorphonuclear cells occur during HD. Activation of polymorphonuclear cells may induce activation of coagulation and fibrinolysis, leading to endothelial cell damage, augmented by release of proteases such as elastase.
