Cytokine and growth factors complex in children with vesico-ureteral reflux

Abstract

In order to reveal the role of cytokines and growth factors in renal scar formation in children with chronic pyelonephritis (CP) and vesico-ureteral reflux (VUR) 360 patients with impaired urodynamics aged from 5 to 15 years were examined. In all of them the 24 hours urine excretion of tumor necrosis factor (TNF-α), interleukins-1, -6, -8, -10 (IL-1, -6, -8, -10) and serum concentration of fibroblast growth factor (FGF), transforming growth factor-β (TGF-β), insulin-like growth factor-1 (IGF-1) have been measured by immunoenzime method. All the children underwent color Doppler ultrasound (CDUS) and nuclear examination of kidneys. Three groups of patients were determined: 1) with VUR and normal X-ray and ultrasound pictures of kidneys (n = 190); 2) with CDUS detected reflux nephropathy (RN) (n = 65); 3) with IVU confirmed reflux nephropathy (n = 85). Patients with CP without VUR (n = 20) were used as controls. As a result, all the patients demonstrated significantly elevated daily urine excretion of cytokines and serum concentration of growth factors in comparison with control (p < 0,05), that may reflect the protraction of covered inflammation in renal parenchyma in remission of CP. The similar dynamics of cytokines and growth factors profile in patients with X-ray confirmed RN and CDUS sings of renal scar formation suggestsing they can be used as early markers of renal tissue damage.
