Background: The use of human intravenous immunoglobulin gamma (IVIG) is associated with thromboembolic events as a complication. There are few reported cases of renal infarction during IVIG use in the general population, but transplant kidney may be more susceptible to thromboembolic events following IVIG use.
Case presentation: A 41-year-old woman visited with fever and pain at the transplant kidney. Six years ago, she underwent kidney transplantation from a deceased donor. Laboratory and radiologic findings were compatible to septic condition, secondary to acute pyelonephritis. We started antibiotics, inotropics, and IVIG. The patient abruptly developed gross hematuria and urine output decreased to 100 cc/day during IVIG administration. Renal doppler and pathologic findings revealed renal infarction. Oliguria and azotemia persisted and she is undergoing maintenance hemodialysis.
Conclusion: Our case shows that infarction of transplant kidney can be caused by IVIG use in a patient with severe infection. Thus, when using IVIG for kidney transplant patients with high risk of thromboembolic events, we may be careful to prevent the thromboembolic events.
