In the USA, a man with a kidney transplanted from a pig lived for a record 9 months.

American Tim Andrews from New Hampshire had a genetically modified pig kidney removed nine months after its transplantation. The organ functioned longer than all previous similar transplants, but it had to be removed due to gradual failure. This was reported on October 27 by The Wired.

"The organ functioned for almost nine months, longer than previous pig organ transplants, before it was removed on October 23," the publication says.

It is noted that the patient had been on dialysis for more than two years due to kidney disease, which had passed into the terminal stage. The genetically edited pig kidney was transplanted on January 25, because a man with a rare blood type could not find a human donor, writes The Wired.

The doctors were able to overcome the acute rejection of the foreign organ, and the kidney functioned for nine months. However, on October 23, she had to be removed due to developing chronic insufficiency.

Despite the removal of the organ, the eGenesis company, which was engaged in genetic modification, considers the operation to be successful, the newspaper reports. The Massachusetts General Hospital plans to perform the next pig kidney transplant to humans before the end of the year.

"Andrews will now resume dialysis and remain on the human kidney donation list," concludes Wired.

How will the introduction of a new diagnostic technique into medical practice make the work of doctors easier?

On October 9, it was reported that scientists had successfully performed liver transplantation from a genetically modified pig to a living human for the first time. The donor liver functioned, supporting the metabolism and synthesis of coagulation factors, and early complications were controlled.

A team of researchers has transplanted an auxiliary liver from a genetically modified pig to a patient with a large liver tumor that cannot be resected. The donor liver was specially modified using 10 targeted genetic modifications, including the removal of xenogens and the introduction of seven human genes responsible for the immune and coagulation systems.
