Intravenous gammglobulin-associated acute renal failure

Intravenous gammaglobulins are used for the treatment of various auto-immune hematological disorders. Renal failure is a relatively rare, but an increasingly recognized side effect of gammaglobulin therapy. Although the renal failure is usually reversible, renal replacement therapy is required occasionally. A high index of suspicion, early recognition and appropriate intervention can prevent this complication. We herewith describe two patients with an immune hematological disorder, who developed acute renal failure after treatment with intravenous gammaglobulins. A brief review of the possible risk factors, pathophysiology and management of this complication is provided.
