Researchers from the Netherlands report in the New England Journal of Medicine that they have found a way to increase the chances that kidneys from deceased donors will succeed after transplant, thus sparing patients from expensive follow-up care or even another organ transplant. In the largest and first study of its kind, doctors compared two existing ways of preserving kidneys taken from deceased donors - in cold storage in an ice pack, or via cold perfusion, which involves hooking the kidney up to a machine that pumps a chilled blood-like solution throughout the organ.

...year, 94% of the kidneys that were perfused had survived once transplanted, compared with 90% of the cold-stored kidneys. More significantly, 26% of the cold-stored organs failed to function in the first weeks after transplant, compared with only 21% of the kidneys that were perfused. While the differences were small, say experts, they can be significant when you consider the costs of dialysis and follow-up care for failed transplants. "Four percent may not appear to be a lot, but if this difference persisted across the country, that would be a significant cost benefit on behalf...
Currently, about 62% of kidneys transplanted each year in the U.S. are harvested from deceased donors; many of those organs cannot be transplanted if they aren't correctly preserved. Past studies have shown that a kidney must be transplanted within 24 hours to lessen the risk of failure in its new host. Most organ centers handle kidneys pre-transplant by washing, then submerging them in a preservation solution and melting ice. But recent evidence has suggested that perfusion machines, which have been around since the 1970s, might do a better job of maintaining the organs and perhaps promote survival once...
...trial involving patients from the international organ exchange group called Eurotransplant. Researchers procured a pair of kidneys from 336 deceased donors and, within 24 hours, placed one from each pair in cold storage, and attached the other to a LifePort Kidney Transporter perfusion machine. The kidneys were then transplanted into 672 recipients. Among the patients who received a cold-stored kidney, 89 developed a condition called delayed graft function in which the kidney fails to function immediately after transplant. Only 70 of the machine-preserved kidney patients developed the complication - meaning that the perfused kidneys had 12% better graft survival...
...Three are measured. As the various aid packages were being negotiated, first on Capitol Hill and then this week on the other side of Pennsylvania Avenue, one constant condition Republicans insisted upon was Detroit getting its wages and benefits down to the levels of the so-called transplant workers in states like Alabama, Tennessee, Georgia and Mississippi.
