Prolonged immunosuppression preserves nonsensitization status after kidney transplant failure.

Background When kidney transplants fail, transplant medications are discontinued to reduce immunosuppression-related risks. However, retransplant candidates are at risk for allosensitization which prolonging immunosuppression may minimize. We hypothesized that for these patients, a prolonged immunosuppression withdrawal after graft failure preserves nonsensitization status (PRA 0%) better than early immunosuppression withdrawal.
