OBJECTIVE: To study the effect of non-ionic contrast medium on renal function in children with cardiovascular disease. METHODS: Analysis of renal function in 98 children with cardiovascular disease before and after the use of Iopamidol, Iohexol, and Ioversol was done for angiography. Serum creatinine (s-Cre), urinary N-acetyl-beta-D-glucosaminase (u-NAG), urinary beta 2-microglobulin (u-BMG), and urinary alpha 1-microglobulin (u-AMG) levels were evaluated. RESULTS: Although s-Cre levels remained unchanged, u-NAG/Cre, u-AMG/Cre and u-BMG/Cre significantly increased 12 hours after angiography. Levels of u-NAG/Cre, u-BMG/Cre, and u-AMG/Cre after angiography were significantly higher in neonates and infants (age< 12-months, n=32) than in children (age>1-year, n=61), in patients with more than 5 ml/kg of contrast medium (n=25) than in those with less than 5 ml/kg (n=70) and in cyanotic patients (n=13) than in non-cyanotic (n=80) patients. CONCLUSION: Transient renal tubular dysfunction occurred in all of these three non-ionic contrast mediums. Although renal tubular function was intact on a long-term basis, one should be careful of contrast medium-induced nephropathy, especially in neonates and infants, in patients receiving more than 5 ml/kg of contrast mediums in total, and in patients with cyanotic heart disease in using non-ionic contrast mediums.
