Background:The aim of the present study was to estimate the total antioxidant status (TAS) and main antioxidant enzyme activity in children with nephrotic syndrome (NS).Material/Methods:The study was carried out in a group of 82 children with NS, age 4–16 years (mean 7.4). Of these, 59 with a first episode formed group I, and 23 children in remission (>6 months, with no immunosuppressive treatment) formed group II. TAS was estimated using the two-reagent Randox Total Antioxidant Status test in plasma.Results:TAS was significantly reduced in group I compared to controls (0.77±0.14 mmol/l vs. 1.18±0.42 mmol/l; p
