Association of Immunosuppressive Maintenance Regimens With Posttransplant Lymphoproliferative Disorder in Kidney Transplant Recipients

Association of Immunosuppressive Maintenance Regimens With Posttransplant Lymphoproliferative Disorder in Kidney Transplant Recipients: Background. The association of immunosuppressive regimens (ISRs) with posttransplant lymphoproliferative disorder (PTLD) may be related with the Epstein-Barr virus (EBV) recipient serostatus.
Methods. We selected primary kidney transplant recipients from Organ Procurement Transplant Network/United Network for Organ Sharing database (2000–2009) who were discharged with a functioning graft and were receiving an ISR including an antiproliferative drug and a calcineurin inhibitor as follows: mycophenolate mofetil (MMF)/mycophenolate sodium+tacrolimus (TAC), MMF+cyclosporine A (CsA); mammalian target of rapamycin inhibitor (mTORi)+TAC; and mTORi+CsA. Adjusted risks of PTLD, rejection, death, and graft failure were examined in all recipients and compared between EBV+ and EBV− recipients.

Kidney Transplantation With Minimized Maintenance: Alemtuzumab Induction With Tacrolimus Monotherapy-An Open Label, Randomized Trial

Kidney Transplantation With Minimized Maintenance: Alemtuzumab Induction With Tacrolimus Monotherapy-An Open Label, Randomized Trial: Background. Immunosuppressive regimens for kidney transplantation which reduce the long-term burden of immunosuppression are attractive, but little data are available to judge the safety and efficacy of the different strategies used. We tested the hypothesis that the simple, cheap, regimen of alemtuzumab induction combined with tacrolimus monotherapy maintenance provided equivalent outcomes to the more commonly used combination of interleukin-2 receptor monoclonal antibody induction with tacrolimus and mycophenolate mofetil combination maintenance, both regimens using steroid withdrawal after 7 days.
