Extract

New technologies are changing our lives radically and quickly. New biotechnologies are moving to commercial uses faster than government regulators or private citizens can monitor. This tension manifests itself in the current debates over xenotransplantation technologies in medicine. The possibility of removing cells, tissues, and organs from animals and transplanting them into human beings is startling and unnerving. Natural immunesystem barriers between species, and even between individuals within a species, are formidable. Typically, transplantation results in violent rejection and death of the grafted organ. But despite the natural barriers to transplantation, xenotransplantation aims specifically to overcome them.

In this paper, I will discuss applications of xenograft technology, which raises clinical risks, ethical concerns, and policy issues. I conclude with a set of specific recommendations. As a recent letter to the journal Nature puts it, there is a “split between those who want to get it right, and those who want to get it right now.” No one knows what all the risks, benefits, and unintended consequences of xenotransplantation will be.

CDC's animal virus expert Chapman tells the following. In 1993, she was asked to consider the possibility of new germs passing into the human population through xenotransplants, and she thought the question silly, not deserving the expenditure of public dollars. But as she looked into xenotransplants, she changed her mind. She now spends most of her professional time on xenotransplant issues, because it is now known that a number of viruses, including some retroviruses (like HIV) and endogenous viruses can and do move between species.Google Scholar
Simian immune viruses (SIVs), which are present in any simian species, do not apparently affect their hosts. They are thought, however, to be the origin of HIV-1 (from chimpanzees), and HIV-2 (from sooty mangebey monkeys). SIV infection of humans has been documented in a person working in a primate lab. An outbreak in Germany in 1967 of Marburg virus (from lab monkeys) infected 31 people and was 23 percent fatal. Ebola, a filovirus, infected at least 220 people in Zaire in 1976, with an 88 percent fatality rate. A shepherd in Pakistan underwent surgery while infected with a type of hemorrhagic fever from domestic animals, thus exposing 17 people with a 24 percent fatality rate.

Known zoonoses detected by laboratory tests include salmonella, herpes B virus of monkeys, and toxoplasmosis.

Goodman, N., Letter, “This is Where I Start to Draw the Line,” British Medical Journal, 313 (1996): 696. Neville Goodman says this: Shows how blinkered some human beings can be. The problem of viral infection was seen as a risk—which might be worth taking ‘in the quest to end human suffering.’ As if human suffering, in the global sense, has anything to do with a lack of organs. It makes me uneasy to think that many doctors do not seem to even think about these things. If they did, they might at least modify their rhetoric and stop inflating the importance of their interests. Id.Google Scholar
Note that the same sort of confusion and disagreement exists in later discussion of life patenting and xenotransplant, about which the commissioner of the Patent and Trademark Office has felt impelled to speak out on an application of chimera xenografting processes made by antibiotech activists, when technically and presumably morally equivalent patents have already been approved. These include technology to get cows to produce in their mammary glands the drug AAT (to treat cystic fibrosis); a xenograft process to move human immune complements into pigs, thereby making pigs' organs less “foreign” to human organ recipients' immune systems; a process to produce a blood-clot regulator in goats; and one to make a tissue plasminogen activator.Google Scholar
