Genetically Modified Pig Kidney Keeps Man Alive For Record Nine Months

A genetically modified pig kidney [1]kept a 66-year-old man off dialysis for a record nine months , marking the longest survival yet for a pig kidney transplanted into a living person and the first time such an organ successfully served as a bridge to a later human transplant. The Guardian reports:
> Tim Andrews was seriously ill with end-stage kidney disease caused by type 2 diabetes and had only a 9% chance of receiving a human kidney within five years, against a more than 40% risk of dying or being removed from the waiting list. Kidney transplantation provides the best survival and quality of life for patients with end-stage kidney disease, but global demand for human organs far exceeds supply.

> Surgeons in the US successfully transplanted a kidney from Wilma, a Yucatan miniature pig, into Andrews, after genetically engineering it to be compatible with his immune system. The kidney kept Andrews free of dialysis for a record nine months, the longest period ever recorded, before it began failing and he received one from a dead human donor. It was also the first time a pig's kidney had been used as a temporary "bridge" to a human transplant.
The breakthrough has been [2]detailed in the journal Lancet .
