STATUS OF PRO- AND ANTICOAGULANT COMPONENTS OF HEMOSTASIS IN PATIENTS WITH STAGE VD CKD DEPENDING ON RESIDUAL RENAL FUNCTION.

OBJECTIVE The aim: To study the status of pro- and anticoagulant components of hemostasis in patients with stage VD CKD depending on residual renal function. PATIENTS AND METHODS Materials and methods: 88 patients with stage VD CKD were studied, 16 of them had preserved residual renal function (RRF). Hemostatic parameters - soluble fibrin, D-dimer and protein C - were determined in the patients. RESULTS Results: Significant increase in soluble fibrin and fibrinogen levels along with depressive reaction of D-dimer and protein C were found in patients with stage VD CKD having lost RRF. Preserved RRF in those patients had positive influence on hemostatic profile, decreasing the degree of hypercoagulation. CONCLUSION Conclusions: 1. In long term dialysis patients with stage VD CKD and lost RRF, significantly increased levels in soluble fibrin and fibrinogen along with decreased D-dimer concentration were found, being a key factor in the development of thrombotic complications. 2. There was significant decrease in protein C activity in patients with lost RRF. 3. Preserved RRF in patients with stage VD CKD had positive influence on hemostatic profile.
