Kidney Transplant Program at the Mayo Clinic in Arizona.

Abstract

Since 1999, we have performed 2,302 kidney transplants at the Mayo Clinic in Arizona. Transplant volume has increased by 45% since 2010. Our center performed 269 kidney transplants in 2013. Our growth is related to multiple factors, including an experienced, committed team and strong support from our institution and referring nephrologists. Areas of program innovation at our center include: transplanting deceased donors with acute kidney injury, outcomes in older kidney transplant recipients, alemtuzumab induction with steroid avoidance, living donor paired kidney exchange-3 site experience, and other non-traditional deceased donor kidney transplants. Of the 162 acute kidney injury (AKI) donor transplants done at our program, 71% had severe AKI. The AKI donor kidneys had more delayed graft function; but graft survival, estimated glomerular filtration rate, and biopsy findings at 1 year were not different form the control group. We have transplanted 188 patients ≥ 70 years old at the time of transplantation. Graft survival at 1, 3, and 5 years was similar to that of patients < 70. Since 2008, 778 (37%) patients received alemtuzumab induction, therapy with excellent patient and graft survival. We have used steroid avoidance immunosuppression with excellent outcomes since 2003. Since starting kidney paired donation in 2009, it has resulted in 54 kidney transplants, including 4 compatible pairs. More than half of the deceased donor transplants done at our center are from non-traditional donors such as Public Health Service increased risk, donation after cardiac death, extended criteria donors/high kidney donor profile index, and pediatric en-bloc donors. One- and 3-year graft survival of the non-traditional deceased donor kidney transplants are not different than the traditional deceased donor kidney transplants.
