Posttransplant lymphoproliferative disorder (PTLD) can be resolved in many transplant patients by the reduction or cessation of immunosuppression, after which many grafts continue to function as the result of a form of operational tolerance. When graft function deteriorates, retransplantation may be an option. Cytokines such as interleukin (IL)-10 and IL-18 may play a role in PTLD tolerance induction and tumor regression. We report long-term follow-up on the duration of graft tolerance and the course of retransplantation in a series of patients who underwent kidney transplantation and demonstrated PTLD, and in whom we were able to perform IL-18 analyses.
