NUNZIUM

A significant leap forward in xenotransplantation has been made by surgeons at the New York University Langone Transplant Institute in the United States. For the first time ever, a pig kidney has been successfully transplanted into a human body and functioned normally for over a month. This medical milestone represents the longest a pig kidney has ever functioned in a human body.

The unique opportunity for this revolutionary procedure was presented when the family of Maurice "Mo" Miller, a 57-year-old man who passed away suddenly, generously donated his body for scientific use. The pig kidney used in the transplant was genetically modified to eliminate a gene that produces biomolecules usually attacked and rejected by the human immune system. This innovative approach has addressed the long-standing issue of immune system rejection in xenotransplantation, the process of transplanting organs from animals to humans.

This medical breakthrough brings hope to the over 103,000 people in the US currently awaiting organ transplants, of which 88,000 are in need of kidneys. Thousands lose their lives each year while on the waiting list, and the successful use of genetically modified pig organs could significantly decrease this number. The potential of xenotransplantation is such that the US Food and Drug Administration (FDA) is considering permitting small, selective studies of pig heart and kidney transplants in volunteer patients.

This achievement follows a similar success by the University of Alabama at Birmingham, which reported a successful transplantation of a pair of pig kidneys into a donated body, functioning without issue for seven days. However, challenges and uncertainties remain in the field of xenotransplantation. Last year, a gene-edited pig heart transplant performed by surgeons at the University of Maryland resulted in the recipient surviving only two months before the organ failed. The reactions of a live patient to a pig organ and the longevity of such experiments remain unclear and reliant on the stability of the donated body.

The successful operation involved doctors Adam Griesemer and Jeffrey Stern traveling hundreds of miles to retrieve kidneys from genetically modified pigs housed by Revivicor Inc., a Virginia-based company. The pig's thymus was attached to the transplanted kidney to increase human tolerance of the organ, and the team used standard immune-suppressing drugs employed in current transplant procedures.

In conclusion, xenotransplantation stands on the threshold of a new era. The successful transplantation of a pig kidney into a human body, functioning for over a month, is a beacon of hope for those awaiting organ transplants. As the potential to save lives using animal organs becomes more tangible, a new wave of optimism washes over the medical community and beyond.
