When a Gift From the Heart Is a Kidney
However, there is a critical shortage of donor organs, and many people who need a new kidney languish for as long as five years on waiting lists, making the idea of nondirected donation worth considering. In addition, advances in surgical techniques and in drugs that prevent the recipient's body from rejecting an organ from a nonrelated donor have made the surgery more successful.
"There has been an evolution of thought," Matas tells WebMD. "Twenty years ago our argument was that there are risks to the donor operation and that there would be no advantage to a living unrelated donor vs. a cadaver donor, therefore there's no justification to put the donor through those risks. Over the last two decades we've learned that the results of living unrelated donor [kidney] transplants are similar to living related donor transplants, and it sort of changes the equation in terms of risks and benefits, because now you have the same risks as we're putting the related donors through and in fact the same benefits."
Although accepting the sacrifice of healthy organs from altruistic individuals could help to ease the growing shortage of donor organs -- already at critical levels, transplant surgeons say -- it could also be the start of a slippery slope toward the competition and commercialization of organ procurement, some observers warn. And there is also the fear among some people that there may be an unintentional tendency to downplay the risk of donation in order to get an organ.
"The program as described from Minnesota strikes me as well put together and reasonable, but my concern is that they will not be the only transplantation program to institute this way of getting living donors [for kidney transplantation]," Norman Levinsky MD, tells WebMD. "In a competitive environment where it's important to a program to shorten the wait of their recipients to less than three, four, or five years -- in other words to get some of their most needy recipients to the head of the line -- there might be shadings of meaning or body English, which are totally unintended but which minimize the risks of discomfort at the least, and the remote but not zero risk of death," says Levinsky, professor of medicine at Boston University Medical Center, who wrote an editorial accompanying the article.
"It's a gray area, but I think if you look at it both from an ethics perspective, and perhaps from a basic science perspective, it's not a surprise, and it's something that people have been thinking and talking about for a long time," bioethicist Mary Faith Marshall, PhD, tells WebMD. "I actually have seen it as something inevitable and I don't see it as a bad thing. From a moral perspective I see nothing wrong with [nondirected donation] as long as there are procedural safeguards in place, and especially psychological ones, for the people who are involved." Marshall is director of the Program in Bioethics at Medical University of South Carolina in Charleston.
