Groundbreaking Pig Kidney Transplant Offers Hope to Alabama Woman and Organ Shortage Crisis
In a momentous medical achievement, Towana Looney, a 53-year-old Alabamian suffering from kidney failure, has become the third person in the United States to receive a kidney transplant from a genetically modified pig. This pioneering surgery, carried out by surgeons at NYU Langone Health, was announced on Tuesday after Ms. Looney underwent the procedure just before Thanksgiving, following an exhausting eight-year wait for an organ.
Surgeons revealed that Ms. Looney was in notably better health compared to previous recipients of porcine organs and was able to leave the hospital a mere 11 days post-surgery. However, she has since returned for intravenous infusion treatments because she carries high levels of antibodies which complicate the search for a compatible human donor kidney.
The transplant community is closely observing Ms. Looney's case, as its success could expedite further clinical trials and introduce pig transplants as a viable solution to the pressing organ supply crisis affecting more than 100,000 Americans awaiting organ transplants, particularly kidneys. Of those waiting, over 90,000 are in urgent need of kidneys, driven by a stark organ shortage where fewer than 30,000 are available each year from deceased or living donors.
Post-surgery reports indicate that Ms. Looney's new kidney began functioning immediately; medical tests show it's effectively clearing waste products from her system. Dr. Robert Montgomery, director of the NYU Langone Transplant Institute and one of the lead surgeons, stated that Ms. Looney's condition is critical in evaluating the future of xenotransplantation, where genetically modified organs from animals might become an essential alternative for patients in desperate need.
"I’ve never felt better,” Ms. Looney enthusiastically shared, noting her new-found ability to perform daily household tasks that were once strenuous during her long-term dialysis treatment. She is now eagerly planning trips, including a long-desired visit to Disney World, free from the burden of scheduling dialysis sessions during travel.
Dr. Jayme Locke, who co-led the surgery and previously directed the Incompatible Kidney Transplant Program at the University of Alabama at Birmingham, emphasized the significance of Ms. Looney's case, given the unprecedented nature of kidney transplantation from genetically modified pigs. "This was in many ways her only option,” Dr. Locke remarked, explaining the challenges Ms. Looney faced in securing a compatible human organ due to her unique antibody profile.
This groundbreaking surgery was approved by the Food and Drug Administration (FDA) under its expanded access program, which permits unapproved treatments for life-threatening conditions. The kidney was sourced from a pig that underwent ten genetic modifications to facilitate compatibility with the human immune system, a crucial step in reducing the risk of rejection.
This transplant represents a new chapter in the realm of organ transplantation. While other patients have previously received porcine organs, most have been in dire health conditions and faced grim outcomes shortly after the surgery. In contrast, Ms. Looney has a background as an organ donor herself—having donated a kidney to her mother—establishing a precedence for her high-ranking status on the waiting list for a human organ.
As the medical community holds its breath, the coming weeks will be pivotal in determining the viability of pig kidney transplantation. If it proves successful in the long term, it may indeed open doors for future treatments and solve the organ shortage crisis faced by many across the nation.
