The aim of research was to study the levels of thrombomodulin (TM) and von Willebrand factor (VWF) in the serum and urine of patients with chronic kidney disease (CKD)as diagnostic markers of endothelial dysfunction. The study involved 140 patients with CKD. The clinical diagnosis was determined based on standard methods of patients examination according to the kidney diseases classification and protocols of CKD patients management. The concentrations of TM and VWF in serum and urine were quantified by ELISA. A generalized endothelial dysfunction in the vessels of the whole body, including the kidneys and high concentration of TM and FVF in the serum and urine of patients with a diabetic nephropathy have been found. The concentration of TM and VWF in the serum of patients with a chronic glomerulonephritis was at the same level as in the serum of healthy individuals, while those in urine significantly exceeded the control values, indicating endothelial damage in the glomeruli of the kidneys due to exposure to pro-inflammatory cytokines. In our opinion, the studied markers will contribute to the timely diagnosis of endothelial dysfunction in patients with CKD and to the development of criteria for prescribing antiplatelet agents in glomerular kidney disease.
