Alabama woman who lived with Pig kidneys The organs were removed after her body began rejecting it for a record 130 days and returned to dialysis, doctors announced Friday.
Towana Rooney He recovered steadily from his April 4 removal surgery at Nyu Langone Health and returned to Gadsden, Alabama. In a statement, she thanked the doctors for “an opportunity to participate in this incredible study.”
“The outcome is not something anyone would have wanted, but I know I've learned a lot from pig kidneys since 130 days, and I know this can help and stimulate many others on my journey to overcome kidney disease,” added Rooney.
Scientists are Genetically transforming pigs Therefore, their organs are more human-like to deal with a serious shortage of transplantable human organs. Over 100,000 people are on the US transplant list, most need kidneys, and thousands wait and die.
Before the Rooney's transplant, only four other Americans had undergone an experimental xenograft plant of gene-edited pig organs – Two hearts and Two kidneys It continued within two months. The recipient, who had been seriously ill before the surgery, died.
Now, researchers are trying to transplant these with patients with slightly fewer illnesses, such as Rooney. a New Hampshire Man Those who received pig kidneys in January are doing well, and this summer, a rigorous study of pig kidney transplants has been set up. Chinese researcher He also recently announced the success of a renal xenogenetic transplant.
Rooney has been on dialysis since 2016 and was not eligible for regular transplants. Her body was abnormally prepared to reject human kidneys. There she searched for pig kidneys, and it worked well – she called herself a “superwoman” and lived longer than anyone who had previously gene-edited pig organs from her November 25th until early April, when her body began to reject it.
Dr. Robert Montgomery, a pioneer of the Nyu XenoTransplant, Robert Montgomery, a Rooney surgeon, said the rejection was under investigation. However, he said Rooney and her doctors agreed that removing pig kidneys is less risky than trying to store it with a higher and higher risk rejection drug.
“We did something safe,” Montgomery told The Associated Press. “She's not worse than before (XenoTransplant). She said it was better because she took the last four months' break from dialysis.”
Shortly before rejection began, Rooney suffered from infections related to the previous time-related to dialysis, but immunosuppressive anti-rejection drugs had slightly reduced, Montgomery said. At the same time, her immune system was revitalizing after the transplant. These factors could be combined to damage new kidneys, he said.
Rejection is a common threat after human organ transplantation, and can also cost patients new organs. Doctors face balanced behaviors so that they can suppress the patient's immune system and fight infections while maintaining new organs.
That is an even bigger challenge with xenotransplants. Although these pig organs have been altered to prevent immediate rejection, patients still require immunosuppressive medications. Another xenograft plant pioneer, Dr. Kawakai of Massachusetts General Hospital, said it was best to prevent which drugs differ, and that the subsequent form of rejection was not clear. Different research groups use different combinations, he said.
“If you have more experience, you'll see what kind of immunosuppression is really necessary for xenografts,” Kawai said.
Montgomery said Rooney's experience provides valuable lessons for future clinical trials.
Ultimately making a xenograft would “be a single and double win, rather than swinging for the fence every time you do any of these,” he said.
