The National Kidney Registry (NKR) is a national registry in the United States listing kidney donors and recipients in need of a kidney transplant. NKR facilitates over 450 "Kidney Paired Donation" (KPD) or "Paired Exchange" transplants annually. [1] [2]
More than one-third of potential living kidney donors who want to donate their kidney to a friend or family member cannot because of blood type or antibody incompatibility. [3] Historically, these donors would be turned away and the patient would lose the opportunity to receive a life-saving kidney transplant. KPD overcomes donor-recipient incompatibility by swapping kidneys between multiple donor-recipient pairs, and connecting them in longer chains, as well as taking an altruistic non-directed donor, and start chains of kidney transplants.
What the NKR does is consolidate the incompatible pairs of donors and recipients from transplant centers all over the United States, into a single registry, and facilitate the transplant process.
The NKR was founded in 2007 by the Hil family, after their youngest daughter lost her kidney function at age ten. Both parents were ruled out from donating to their daughter because they were biologically incompatible. After many unsuccessful attempts to find a compatible donor through all of the kidney paired exchange programs in the United States, a compatible donor was found. After this transplant ordeal, the Hil family founded the National Kidney Registry to eliminate the problem of incompatible donors, by building a national kidney paired donation (KPD) program. [4]
The NKR organized its first swap on Valentine's Day in 2008 at Cornell Medical Center in New York City. [5] This first swap was a 3-deep chain that ended with a bridge donor who donated two months later, extending the chain to 5-deep. [6] This chain was broken after the bridge donor reneged following many failed cross matches that required the donor to repeatedly go to the hospital for blood draws.[ citation needed ]
The NKR's second swap started with the shipment of a kidney from Cornell to UCLA School of Medicine. This was the first time a living donor kidney was shipped on a commercial airplane. This second chain crossed the country three times, facilitating eight total transplants at UCLA, Cornell, Stanford University School of Medicine, and California Pacific Medical Center. [7] Ultimately, this chain was broken when the bridge donor reneged.[ citation needed ]
Based on these early experiences, many safeguards were implemented to reduce the risk of broken chains, which dropped the frequency of broken chains from 33% in 2008 to 2% in 2015. [2]
In 2012, the NKR broke the world record for the largest kidney swap by organizing a 30-deep chain involving 60 donors and recipients. This chain was started by Rick Ruzzamenti, a 44-year-old from Riverside, California. The swap took four months to complete and involved 17 different transplant centers across 11 states. [8] Three years later, on March 26, the next record breaking chain was set into motion by Kathy Hart, a 48-year-old attorney from Minneapolis. This swap took two months to complete and involved 26 different transplant centers. [9]
The NKR has facilitated 3214 kidney transplants, as of March 17, 2019. [10]
The rapid growth of KPD transplants in the United States has been driven by the following key NKR innovations.
The NKR's innovations have generated significant media coverage including a front-page story in the New York Times . [27] and nationally televised interviews by Katie Couric with the CBS Evening News . [28] Diane Sawyer from ABC News, [29] and Byron Pitts at Nightline . [30]
Organ donation is the process when a person authorizes an organ of their own to be removed and transplanted to another person, legally, either by consent while the donor is alive, through a legal authorization for deceased donation made prior to death, or for deceased donations through the authorization by the legal next of kin.
Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location. Organs and/or tissues that are transplanted within the same person's body are called autografts. Transplants that are recently performed between two subjects of the same species are called allografts. Allografts can either be from a living or cadaveric source.
Transplant rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue. Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of immunosuppressant drugs after transplant.
Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood, in order to replicate inside a patient and produce additional normal blood cells. HSCT may be autologous, syngeneic, or allogeneic.
Kidney transplant or renal transplant is the organ transplant of a kidney into a patient with end-stage kidney disease (ESRD). Kidney transplant is typically classified as deceased-donor or living-donor transplantation depending on the source of the donor organ. Living-donor kidney transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, depending on whether a biological relationship exists between the donor and recipient. The first successful kidney transplant was performed in 1954 by a team including Joseph Murray, the recipient's surgeon, and Hartwell Harrison, surgeon for the donor. Murray was awarded a Nobel Prize in Physiology or Medicine in 1990 for this and other work. In 2018, an estimated 95,479 kidney transplants were performed worldwide, 36% of which came from living donors.
Canadian Blood Services is a non-profit charitable organization that is independent from the Canadian government. The Canadian Blood Services was established as Canada's blood authority in all provinces and territories except for Quebec in 1998. The federal, provincial and territorial governments created the Canadian Blood Services through a memorandum of understanding. Canadian Blood Services is funded mainly through the provincial and territorial governments.
The United Network for Organ Sharing (UNOS) is a non-profit scientific and educational organization that administers the only Organ Procurement and Transplantation Network (OPTN) in the United States, established by the U.S. Congress in 1984 by Gene A. Pierce, founder of United Network for Organ Sharing. Located in Richmond, Virginia, the organization's headquarters are situated near the intersection of Interstate 95 and Interstate 64 in the Virginia BioTechnology Research Park.
The National Marrow Donor Program (NMDP) is a nonprofit organization founded in 1987 and based in Minneapolis, Minnesota, that operates the Be The Match Registry of volunteer hematopoietic cell donors and umbilical cord blood units in the United States.
The National Organ Transplant Act (NOTA) of 1984 is an Act of the United States Congress that created the framework for the organ transplant system in the country. The act provided clarity on the property rights of human organs obtained from deceased individuals and established a public-private partnership known as Organ Procurement and Transplantation Network (OPTN). The OPTN was given the authority to oversee the national distribution of organs.
Organ trade is the trading of human organs, tissues, or other body products, usually for transplantation. According to the World Health Organization (WHO), organ trade is a commercial transplantation where there is a profit, or transplantations that occur outside of national medical systems. There is a global need or demand for healthy body parts for transplantation, which exceeds the numbers available.

Kidney paired donation (KPD), or paired exchange, is an approach to living donor kidney transplantation where patients with incompatible donors swap kidneys to receive a compatible kidney. KPD is used in situations where a potential donor is incompatible. Because better donor HLA and age matching are correlated with lower lifetime mortality and longer lasting kidney transplants, many compatible pairs are also participating in swaps to find better matched kidneys. In the United States, the National Kidney Registry organizes the majority of U.S. KPD transplants, including the largest swaps. The first large swap was a 60 participant chain in 2012 that appeared on the front page of the New York Times and the second, even larger swap, included 70 participants and was completed in 2014. Other KPD programs in the U.S. include the UNOS program, which was launched in 2010 and completed its 100th KPD transplant in 2014, and the Alliance for Paired Donation.

He is also known for his role in getting the HIV Organ Policy Equity Act signed into law.
Donor-specific antibodies (DSA) are a concept in transplantation medicine and describe the presence of antibodies specific to the Donor's HLA-Molecules. These antibodies can cause antibody-mediated rejection and are therefore considered a contraindication against transplantation in most cases. DSA are a result of B cell and plasma cell activation and bind to HLA and/or non-HLA molecules on the endothelium of the graft. They were first described in 1969 by Patel et al., who found that Transplant recipients who were positively tested for DSA using a complement-dependent cytotoxicity crossmatch assay had a higher risk of transplant rejection. DSA can either be pre-formed or can be formed as a response to the transplantion.

Optimal kidney exchange (OKE) is an optimization problem faced by programs for kidney paired donations (also called Kidney Exchange Programs). Such programs have large databases of patient-donor pairs, where the donor is willing to donate a kidney in order to help the patient, but cannot do so due to medical incompatibility. The centers try to arrange exchanges between such pairs. For example, the donor in pair A donates to the patient in pair B, the donor in pair B donates to the patient in pair C, and the donor in pair C donates to the patient in pair A.
