Kidney transplant chain

October 23, 2009 about 18 patients who were paired by surgeons as part of a rare transplant chain at UCLA. Each link represented a paired donation in which a donor gives a kidney to a stranger, trusting that another stranger will donate a kidney to his or her loved one in return.

These chains are difficult to build, because of the trust that is needed as well as medical complications. Donors and recipients must have compatible blood types and antibodies. Surgeons usually perform multiple transplants simultaneously in adjacent operating rooms so transplanted kidneys stay healthy and donors do not get sick or back out of the operation and break the chain.

Network officials are developing a national registry that they plan to launch next year with five pilot sites, including UCLA. That could lead to an additional 1,000 to 2,000 kidney transplants annually, according to Dr. Bryan Becker, president of the New York-based National Kidney Foundation.

For now, donor pairs rely on smaller networks, including the National Kidney Registry in Babylon, N.Y., which started keeping a list of paired donors two years ago. UCLA surgeons used the registry to build the latest donor chain, their fifth and one of about a dozen the registry coordinated nationally this year, a spokesman said.

Hospitals generally do not allow members of a transplant chain to meet before their operations in case a donor backs out, however, UCLA surgeons allowed the first few pairs of the latest chain to meet at the hospital the day after the first batch of surgeries.

All are doing well and met for the first time at the hospital on Friday.
