Oxidative Stress in Children and Adolescents with Diabetic Nephropathy

Abstract Background The pathogenesis of diabetic nephropathy (DN) involves multiple factors, and the exact mechanisms remain uncertain. Thus, the aim of the current study is to assess the oxidant/ antioxidant status among children and adolescents with type 1 diabetes(T1D) and diabetic nephropathy (DN). Methods A comparative cross-sectional study including 100 patients with T1D; equally divided into 2 groups according to urinary albumin excretion rate (UAER). Both groups of T1D were compared with age and gender matched healthy controls. To assess oxidant/ antioxidant status, malondialdehyde (MDA) and total antioxidant capacity (TAC) were assessed using colorimetric method. Results The MDA levels were significantly higher in patients with DN (9.24 nmol/ml) compared with patients with normoalbuminuria (1.99 nmol/ml) and healthy controls (0.78 nmol/ml) (P
