Pig Kidney Transplanted into Human for First Time: Richard Slayman's Story Offers Hope to Hundreds of Thousands with Failed Kidneys

Boston, Massachusetts United States of America
On March 21, 2024, a pig kidney was successfully transplanted into a living person for the first time. The patient is Richard Slayman of Weymouth, Massachusetts who had previously received a donated human kidney in 2018 but it failed and he went back on dialysis for over a year before being offered an experimental solution of pig organ transplant.
This breakthrough offers hope to hundreds of thousands of Americans whose kidneys have failed.

  • Deception (50%)
    The article is deceptive in several ways. Firstly, the title implies that this is a medical milestone when it's not entirely accurate as there have been previous successful transplants of genetically modified pigs into humans. Secondly, the author uses sensationalism by stating that if kidneys from genetically engineered animals can be transplanted on a large scale, dialysis will become obsolete which is an exaggeration and not supported by any scientific evidence.
    • The title implies this is a medical milestone when it's not entirely accurate as there have been previous successful transplants of genetically modified pigs into humans.
  • Fallacies (85%)
    The article contains several fallacies. The first is an appeal to authority when it states that the surgery was a medical milestone without providing any evidence or context for this claim. Additionally, there are two instances of inflammatory rhetoric: 'Organs from genetically engineered pigs one day may make dialysis obsolete' and 'End-stage kidney disease is three times more common among Black Americans than among white people'. The article also contains a dichotomous depiction when it states that the patient's condition continues to improve, but then mentions that he is still on dialysis. Finally, there are several examples of informal fallacies such as 'If kidneys from genetically modified animals can be transplanted on a large scale, dialysis will become obsolete'.

Firstly, the author claims that this is a first transplant of a genetically modified kidney from a pig into a living human when it has been done before. Secondly, the author states that doctors thought Slayman's new kidney could last years but also acknowledges there are many unknowns in animal-to-human transplants. Thirdly, the article quotes Dr Parsia Vagefi stating this is a significant medical milestone when it has not been proven to be effective or safe for humans yet. Lastly, the author states that xenotransplantation could solve an organ shortage but does not provide any evidence of its effectiveness.
          • The article claims that this is a first transplant of a genetically modified kidney from a pig into a living human when it has been done before. This statement is deceptive because the author did not do their research and failed to mention previous successful xenotransplants.
          • The author states that doctors thought Slayman's new kidney could last years but also acknowledges there are many unknowns in animal-to-human transplants. This statement is deceptive because it implies a level of certainty and safety when the long term effects of xenotransplantation are not yet known.

              The article is deceptive in several ways. Firstly, the author claims that previous genetically engineered porcine donors have been clinically ready for xenotransplantation into Old World monkeys (OWMs), but this is not true as they are not suitable for human application due to their heart and kidney sizes being too large. Secondly, the author states that these donors lacked glycans necessary for a human-compatible porcine donor, but in fact, renal grafts derived from these animals have been tested in OWMs with short survival times or not all human transgenes expressed. Lastly, the article claims that PERV sequences present a zoonotic risk as they can transmit to human cells and integrate into their genome. However, this is misleading as there are currently no known cases of PERV transmission from animal-to-human in xenotransplantation.

Firstly, the author uses an appeal to authority by stating that main xenotransplantation may offer a transformative solution to the worldwide organ shortage crisis without providing any evidence or citation for this claim. Secondly, the author commits a false dilemma by presenting only two options for creating clinically ready porcine donors: either eliminating growth hormone receptor gene expression or designing them specifically for testing in Old World monkeys (OWMs). The article fails to consider other potential solutions that may be more effective. Thirdly, the author uses inflammatory rhetoric by stating that a human-compatible porcine donor should ideally have all three glycans eliminated without providing any evidence or citation for this claim.
