A kidney chain starts with an altruistic donor who decides to donate a kidney to a stranger instead of to a friend or relative. The altruistic donor gives to a person waiting for a transplant, and that recipient is willing, but incompatible, the donor gives it to another person who is waiting for a kidney, etc. Kidney Donor Chain Creates Opportunities for Endless Donor-Recipient Pairings. It starts with an altruistic donor, someone who wants to donate a kidney out of the goodness of their heart.
That kidney is transplanted to a recipient who had a donor willing to donate a kidney, but it was not compatible. To keep the chain going, the incompatible donor delivers a kidney to a patient unknown to him or her who has been identified as compatible, essentially paying for it. Specialized software connects donors and recipients from all over the country. Paired kidney donation (KPD) is a strategy to help patients with incompatible donors, 3-7 With KPD, 2 or more incompatible couples are paired with other incompatible partners so that multiple compatible transplants can be performed.
Paired kidney donation, also known as closed-circuit kidney exchange, can occur with any number of couples participating in 2-, 3-, or multi-way exchanges, being possible. Variations of KPD incorporate non-directed donors (NDD) to start a chain of compatible transplants. 8 NDDs are willing to donate a kidney without the expectation that someone they know will receive a kidney in exchange. When NDDs initiate chains that result in multiple transplants occurring simultaneously and the chain ends up on the deceased donor waiting list (DDWL), these are called domino paired donor exchanges.
When the “bridge donor”, the last donor in a concurrent transplant group that is still waiting to donate, is used to initiate another group of transplants, these linked groups are considered to be part of an extended non-simultaneous altruistic donor chain 9 Since 1988, it is estimated that 953 NDD (385 blood groups were donated O , 386 blood groups A, 140 blood groups B and 42 blood groups AB), and the numbers increased significantly over the past decade (Figure. I encourage anyone considering donating their kidney to think about the impact they can have on someone else's life. On July 20, Barbara Graybeal from Scottsboro, Alabama, and Betty Griffin from Eufaula, Alabama, became recipients of kidney number 99 and 100, respectively, as part of the UAB Renal Chain. No chain broke in the last 15 months, and all recipients whose incompatible donors donated received a kidney.
The National Kidney Foundation (NKF) is the largest, most comprehensive and oldest organization dedicated to the awareness, prevention and treatment of kidney disease. It starts with a person in need, Recipient A, and someone who wants to donate a kidney to them; maybe a loved one or a friend, but who has been considered an incompatible donor. Williamson's kidney went to Hoover, Alabama, resident Jay Ernst, a 34-year-old husband and father of two who had battled kidney disease for nearly 20 years. That young mother, Allison Nelson from Louisiana, shared her lifelong battle with polycystic kidney disease and how her new kidney would allow her to be there for her children.
Wanda then became what is known as a bridging donor, meaning she would donate her kidney at a later time. Paired kidney donation, or KPD, also called kidney exchange, gives transplant candidate another option. Family members were immediately tested to see if anyone was compatible with donating a kidney to Chelsie, but the search was unsuccessful. Surgery is the beginning of what is called a kidney chain, an interconnected chain of people who need a kidney transplant.
There are approximately 100,000 people on the kidney transplant waiting list from deceased donors, many of whom wait 5 to 10 years before being called by name to receive a kidney. Of the 77 chains initiated by NDT, 4 chains, 10, 2, 1 and 2 long transplants at the end of the study period, remained open and had 1 bridging donor of blood type B, 1 of blood type AB, 1 of blood type O and 1 of blood type O, respectively, still willing to donate their kidney to further extend their chains. We were sure that once the problem of anaemia was resolved, Wanda would donate her kidney to that intended recipient again. .
