- The first baboon-to-human liver transplant looks successful
- so far
-
-
- Protesters outside the University of Pittsburgh Medical
- Center carried signs reading animals are not expendable. But for
- the 35-year-old man recovering inside, the choice had been
- between life and death. In an 11-hour operation, the unidentified
- patient received a new liver to replace his own, ravaged by
- hepatitis B. Since the virus would have also destroyed a
- replacement human liver, doctors transplanted the organ from a
- baboon.
-
- It was hardly the first time a human had received an
- animal transplant; kidneys and hearts have been shifted from
- chimpanzees, baboons and monkeys into people for decades, though
- never successfully. What may make the difference this time is
- an experimental antirejection drug known as FK-506; doctors hope
- it will keep the recipient's immune system from attacking the
- new liver as a foreign object. Though the patient had symptoms
- of a mild rejection reaction by week's end, it wasn't considered
- serious. Otherwise, said a hospital spokeswoman, "he's doing
- really well. It's almost scary."
-
- If this works, it may lead to more widespread use of
- animal organs. Dr. Thomas Starzl, who pioneered animal-human
- transplants and supervised this operation, acknowledged the
- concerns of animal-rights activists but said, "Our passion and
- our commitment is to human beings."
