Abstract

THE AIM. To reveal the informative indicators for the prediction of progression of reflux nephropathy in children with vesicoureteral reflux based on the study of the urinary excretion of markers of sclerosis (transforming growth factor-β1), angiotensin II, procalcitonin, β2-microglobulin) and collagenopathy (peptidoglycans and free hydroxyproline). PATIENTS AND METHODS: the study group included 71 (52 girls) the patient at the age of 5.69±0.44 years with vesicoureteral reflux (VUR). Based on the results of DMSA-scintigraphy, all children were divided into 2 groups: the control group 9 children with VUR without foci of sclerosis and a study group included 62 patients with different degrees of reflux nephropathy (RN). The control group consisted of 20 healthy children at the age of 6.24 ± 0.31 years. In all children investigated the urinary excretion of AngII, TGF-β1, PCT, β2-MG, PSH and FH and counted it to the level of creatinine in the urine. RESULTS. Urinary levels of AngII, TGF-β1, PCT, β2-MG, PSH, and FH was significantly higher in groups of children with RN when compared with the control group. The highest level AngII, TGF-β1, PCT was defined in the main group (p<0.05). Patients with a severe degree of RN, the ><0.05). Patients with a severe degree of RN, thelevel of AngII, TGF-β1, PCT in urine was higher when compared with the control group and the group of children without foci of sclerosis (p<0.05). CONCLUSION. Installed direct correlation between the level of excretion AngII, TGF-β1, PCT and the severity of RN in patients with VUR indicates the feasibility and prospects of their inclusion as diagnostic markers predict the severity of reflux nephropathy.
