The rates of chronic kidney disease and end-stage renal disease have provoked a growing need for kidney transplantation, and the increasing prevalence of other diseases affecting the kidney, such as diabetes mellitus and hypertension, are likely to exacerbate this need.1 The availability of suitable donor organs, however, remains well below need. Of the approximately 100,000 patients on the waiting list in 2016, only 19,000 received a transplant.1,2 Efforts in facilitating donor-recipient matches have focused on improved histocompatibility testing and immunosuppressive therapies, and new initiatives have tested expanding the criteria for donor organs deemed suitable for transplant.3 Another strategy known as paired donation or paired exchange brings together pairs of living donors and recipients in hopes of improving the odds of identifying suitable transplant matches. The approach requires a high degree of care team and medical system coordination yet may offer the best outcomes for patients.1,5
In paired donation, a kidney donor and intended but unmatched recipient agree to participate in a chain of coordinated transplants involving other incompatible donor-recipient pairs. The donor’s organ goes to another patient, and the original intended recipient receives a kidney from another new but matching donor. Paired donation also leverages the improved outcomes and rates of survival associated with living-donor transplants. At 1 year postprocedure, the survival rate for all kidney transplant patients is about 90%, but at 5 years, survival is 65% for those who’d received deceased-donor kidneys compared to 80% among those receiving organs from living donors.5
Use of living-donor kidneys can shorten wait times for transplant recipients, and paired donation can minimize the risk of “orphaned” or unmatched donor kidneys.5,6 It may also encourage living-organ donation since identifying compatible donors can present challenges, even for patients with willing donors. Living-donor transplants, in fact, have decreased over the last decade with the largest decrease occurring among kidney transplants employing living, related donors.1,5
Each donation in paired exchange programs has been shown to generate an additional 2 donors, creating a chain of donated organs to those in the program. While paired-donation chains usually contain about 5 donations or fewer,6 they have been able to facilitate procedures for a remarkable number of patients. The University of Minnesota Health transplant program was recently among the medical centers participating in a chain of 35 nondirected transplants, among the largest in the United States.
The University of Minnesota Health transplant program has long supported living donor and paired exchange transplant efforts. It was the first in the United States to perform a kidney transplant from a nondirected living donor, and its paired exchange program PEP! has performed 150 paired donations through July 2019. University of Minnesota Health physicians also have researched improved surgical procedures and drug regimens for transplant patients7,8 and new approaches to promoting immune system tolerance of transplanted organs.9 The transplant program was among the first cohort selected to participate in COIIN, a consortium launched to improve transplant procedures and expand access to transplant through a re-evaluation of criteria for viable donor organs.3 A new presidential Executive Order encouraging further research into treatments for advanced kidney disease may speed development of therapies, reduce transplant-associated costs, and support development of an artificial kidney, once funding is established.10
The University of Minnesota Health transplant program has more than 50 years of experience in the care of organ and cell transplant patients, including care for those receiving kidney, heart, lung, liver, islet, and pancreas transplants, among others. We manage one of the longest-established programs in the world and have cared for more than 12,000 transplant patients. A participant in the National Kidney Registry, Alliance for Paired Donation, and UNOS Kidney Paired Donation Programs, the University of Minnesota Health Incompatible Kidney Transplant Program is among the most active in the country. Our teams are highly skilled at treating patients who have disorders involving more than one organ, and our nephrology group has been consistently ranked as a top provider by national organizations.
Our kidney transplant program has pioneered kidney transplants in children and in patients with diabetes, and it has transplanted kidneys in patients with concomitant diseases and in those requiring retransplantation. We have performed more than 9,000 kidney transplants. Our program also has experience in living-donor transplants, which can be done before a patient requires dialysis and provides better results. Our established paired exchange program PEP! is an option for those whose donors are not a match. The program has led to more than 150 paired donations to date. We also offer desensitization therapy for patients when identifying a precise donor match is difficult. Our experience and long-established nondirected donor program enabled us to participate in the longest multichain kidney transplantation in the United States. Our pioneering research and health care have dramatically improved transplant survival rates and post-transplant quality of life.
