Abstract :

Objectives: Patients with chronic kidney disease (CKD) are at higher risk of incidence of thromboembolic events. The effect of continuous loss of function of nephrons is a progressive accumulation of uremic toxins. Indoxyl sulfate (IS) is an aggressive uremic toxin exerting proinflammatory and prooxidative properties, which affects multiple signaling pathways. Aim: We examined the association between indoxyl sulfate and activation of the coagulation system in predialysis patients with CKD. Methods: Studies have been conducted on a group of 53 patients with CKD on conservative treatment and 18 healthy volunteers. For the determination of parameters of coagulation ELISA-immuno-enzymatic kits were used, whereas the IS levels were determined by HPLC. The hematological and biochemical parameters were assessed using standard laboratory methods. Results: IS concentration was about three-fold higher in CKD patients compared to controls (p<0,0001). Parameters of coagulation: Von Willebrand factor (vWF), thrombomodulin (TM), tissue factor (TF) and its inhibitor-tissue factor pathway inhibitor (TFPI), prothrombin fragment 1+2 (F1+2) in uremic group were significantly higher than in control group (all p<0,0001). IS levels were positively correlated both with CKD markers and all mentioned above coagulation factors, and these results were also statistically significant (all p<0,0001, r�0,45). Moreover, we found inverse correlation between IS and some hematological parameters (HCT, HGB, WBC, LIM and RBC). Conclusions: The results demonstrate a strong relationship between indoxyl sulfate and coagulation parameters in CKD patients. It opens a new idea that IS can play a crucial role in the occurrence of thromboembolic events in CKD patients.
