Acute Renal Failure following Immunoglobulin Therapy

Intravenous IgG infusion has infrequently been reported to cause acute renal failure. In almost all these reports, a sucrose containing IgG product was believed to be the cause of renal injury. Sucrose-induced osmotic nephrosis has been well described in the literature. In this report, we describe a case of acute anuric renal failure following a large infusion of intravenous IgG containing sucrose. Urine cytology demonstrated typical osmotic injury to the renal tubular epithelial cells. Early recovery of renal function was achieved by dialytic removal of sucrose from the circulation.
