Oxidative stress in children with kidney disease.

The aim of this work was to study the dynamics of oxidative stress in the blood and urine of children with kidney diseases: glomerulonephritis (GN), pyelonephritis (PN), renal failure (RF), and lower urinary tract infections (LUTI). The concentration of conjugated dienes is increased in blood: GN 4 times and RF up to 2 times; and extremely increased in urine: GN 12 times and RF 4 times. The concentration of thiobarbituric acid reactive substances in urine shows a similar trend: GN 7 times, PN 2 times, RF 1.
