Twenty days after his kidney transplant, patient Richard Slayman was able to leave the hospital in the United States. The Brazilian doctor was responsible for the operation

Recently, the world was surprised by the news of a man suffering from kidney failure who received a kidney transplant from a genetically modified pig. Twenty days after the operation, this Wednesday, 3, the patient Richard Slayman, 62, has been released from hospital. The surgery took place at Massachusetts General Hospital, in the United States.




Slayman’s statement about his return home was shared on the hospital unit’s social media. In the conversation, the patient said that this moment, of leaving the hospital with one of the cleanest bills of health he’s had in a long time, is something he’s wanted for years.

“Now it’s a reality and one of the happiest moments of my life”completed the transplant. “I am thrilled to once again spend time with my family, friends and loved ones, free from the burden of dialysis which has affected my quality of life for many years. My recovery is progressing smoothly and in this At this moment I ask for respect for privacy.”he concluded.

The Brazilian doctor ordered the pig kidney transplant

The Brazilian Dr. Leonardo Riella He was the doctor responsible for leading Richard Slayman’s transplant in the United States. In a newspaper interview The globeRiella talked a little about her relationship with surgery. “We worked for months to make the transplant successful. I think seeing him leave the hospital, and being able to go home with a functioning kidney, was a great emotion”He said.

Dr. Leonardo Riella, associate professor of medicine at Harvard Medical School and researcher on the mechanisms of immune regulation and on the development of new therapies to promote tolerance of transplanted organs, says he is convinced that xenotransplantation, i.e. the exchange of organs between different species, it is a viable solution to the world’s organ shortage.

Currently in Brazil alone there are around 66 thousand people on the waiting list for an organ. According to the Ministry of Health, according to data from February 2024, half of the total number, i.e. 33 thousand Brazilians, are waiting for a kidney transplant in the national territory.

How did the pig kidney transplant happen?

Although they seem unusual, the size of the pig’s body resembles that of humans, especially considering the head and trunk. The biggest difference between humans and pigs is the size of their extremities. Evidently we humans have longer arms and legs.

Therefore, according to xenotransplantation studies, the idea of ​​transplanting genetically modified organs from pigs to humans would be the most plausible. As Dr. Leonardo Riella said, this would be one of the best ways to reduce the waiting list for organs worldwide.

Patient Richard Slayman, diagnosed with advanced kidney disease, also suffering from type 2 diabetes and hypertension, was undergoing dialysis sessions. He also received a kidney transplant in 2018 which, unfortunately, was rejected by his body five years after the procedure.

For the operation in question, experts removed genes from the pig that could be harmful to the human body or cause infections. In total, there were 69 genetic changes. Finally, on March 16, 2024, the transplant was carried out and, fortunately, successfully.
