RESUMO
Intravenous immunoglobulin (IVIG) therapy is associated with a number of complications, including rare acute renal failure (ARF). Although the cause of IVIG-associated ARF is unknown, it may be related to the stabilizing agent used in IVIG preparations. ARF following IVIG infusion has not been previously described in children. We report a 4-year-old girl with Kawasaki disease who suffered from ARF following IVIG containing maltose. The previously healthy child had no underlying renal disease. She was given a 2g/kg body weight of IVIG (I.V.-Globulin S, Green Cross, IgG:maltose=1:2) for 10 hours. From the second day of IVIG administration, a gradual reduction of daily urine output was observed with an increase of BUN and creatinine levels, which by the fourth day of treatment reached 43.8mg/dL and 4.7mg/dL, respectively. A conservative ARF treatment resulted in a gradual increase in urine output, together with a decrease in BUN and creatinine levels, which after 7 days returned to normal levels. In view of the increasing use of IVIG in medicine, it is imperative that clinicians be aware of this unusual form of renal injury.
