AbstractRecipients of primary transplants from donation after cardiac death (DCD) donors (n = 40) performed from January 2005 to December 2009 were retrospectively reviewed and compared with recipients of primary transplants from donation after brain death (DBD) donors (n = 142). Patients received rabbit antithymocyte globulin induction and rapid steroid taper (RST; steroids stopped 5 days after surgery). Maintenance immunosuppression included tacrolimus and mycophenolate mofetil. Protocol kidney biopsies, creatinine (Cr), and measured glomerular filtration rate (mGFR; determined by cold iothalamate or 24-h creatinine clearance) were obtained at 1, 4, 12, and 24 months. Kidney biopsies for cause were conducted for unexplained elevated Cr, decline in mGFR, or new proteinuria. Biopsies were graded for rejection according to the Banff criteria. Graft survival at 3 years was 90.0% for DCD recipients and 86.6% for DBD recipients (P = NS). Rejection of any grade diagnosed on any biopsy through the first 2 years occurred in 18 DCD (45%) and 50 DBD (35%) recipients. Rejection of a grade more than Banff borderline occurred in 12.5% DCD and 12.7% DBD recipients. At 2 years, the mean ± SEM Cr and mGFR for DCD recipients with rejection were 1.8 ± 0.29 mg/dL and 59.2 ± 8.5 mL/min versus 1.3 ± 0.11 mg/dL and 67.0 ± 7.8 ml/min for those without rejection. For DBD recipients with rejection, Cr and mGFR at 2 years were 1.7 ± 0.12 mg/dL and 54.0 ± 4.4 mL/min versus 1.4 ± 0.11 mg/dL and 66.6 ± 3.3 ml/min for those without rejection (P = NS). Comparing DCD to DBD, there was no statistical difference in mean Cr or mGFR outcomes. Regardless of group, grafts with delayed graft function had lower 3-year survival. DCD primary kidney transplant recipients treated with rabbit antithymocyte induction and RST have short-term graft survival and function equivalent to DBD recipients. RST appears to be acceptable immunosuppression for DCD recipients.Copyright © 2013 Elsevier Inc. All rights reserved.
