Preoperative treatment of a presensitized kidney transplant recipient with donor-derived transplant acceptance-inducing cells
This report describes the case of patient FR, a 31-year-old recipient of a living-related kidney transplant from a donor against whom he was presensitized. Seventeen days prior to transplantation, a central venous infusion of transplant acceptance-inducing cells (TAICs) was administered to the patient. During the 27-month follow up, the patient experienced no acute rejection episodes under an immunosuppressive regime comprising anti-thymocyte globulin (ATG) induction, corticosteroids and tacrolimus. In a similar manner to the kidney transplant recipients treated preoperatively with TAICs in a previous study, patient FR achieved a state of donor-specific hypo-responsiveness. Most remarkably, the deliberate preoperative exposure of a sensitized patient to the sensitizing alloantigen did not heighten his response; on the contrary, after TAIC treatment and transplantation, HLA-specific antibodies were no longer detectable. The case of patient FR provides further evidence of the safety of pre-transplantation treatment with TAICs.
