PURPOSE: To investigate renal toxicity of high-dose intravenous immunoglobulin(IVIG) in children with Kawasaki disease and idiopathic thrombocytopenic purpura. METHODS: 23 children with Kawasaki disease and 7 children with idiopathic thrombocytopenic purpura who were treated with high-dose IVIG(2 g/kg) were evaluated for the change of urine output, blood urea nitrogen(BUN), serum creatinine(Scr), creatinine clearance(Ccr), tubular reabsorption of phosphorus(TRP), fractional excretion of sodium(FENa), 24hour urine b2-microg1obuin/creatinine(b2MG/cr) ratio and urine microalbumin/creatinine(MA/cr) ratio at post-IVIG 1 and 3 day. RESULTS: There was no significant change of urine output, BUN, Scr, Ccr, TRP, 24hour urine b2MG/cr and MA/cr ratio after high-dose IVIG treatment. Transient increase of FENa at post-IVIG 1 day was the only significant change.
CONCLUSION
There was no significant renal toxicity of high-dose IVIG in children with Kawasaki disease and idiopathic thrombocytopenic purpura who had normal renal function.
