Abstract
Immunologic responses of infants and younger children differ from those of adults. Therefore, application of different pretransplant strategies for antibody depletion in younger ABO-incompatible transplant recipients is appropriate. A 12-month-old male infant with end stage renal disease after acute tubular necrosis was scheduled to undergo kidney transplantation from an ABO-incompatible living donor. He did not undergo pretransplant plasmapheresis, as the titer of the anti-ABO antibody was less than 1：4. After kidney transplantation, posttransplant renal function and anti-ABO titers were stable until posttransplant 2 years.
