IVIG-Induced Acute Kidney Injury Mechanism and Prevention

Introduction to IVIG-Induced AKI

• IVIG carries a black box warning for acute renal failure, indicating FDA recognition of this serious complication, and the FDA label specifically lists nephrotic syndrome as a rare but documented adverse reaction to IVIG administration 1, 2

High-Risk Patient Populations

• Age >65 years represents an independent risk factor for IVIG-induced AKI 3
• Pre-existing renal insufficiency (creatinine clearance <60 mL/min) dramatically increases susceptibility 3
• Diabetes mellitus increases risk through baseline microvascular compromise 3
• Concomitant nephrotoxic medications (NSAIDs, contrast agents, aminoglycosides) compound renal injury 4

Prevention and Monitoring Strategies

• Avoid concomitant nephrotoxic agents (contrast media, NSAIDs, aminoglycosides) to reduce AKI risk 4
• Monitor serum creatinine and BUN closely during and after IVIG infusion, particularly in high-risk patients 2
• Watch for clinical signs of volume overload, especially in cardiac transplant or heart failure patients 2
