Other potential contraindications would include psychosocial contraindications. If the patient, for example, is an active alcoholic or an active intravenous drug abuser or any type of recreational drug user, then those patients are typically not considered for a liver transplantation.
VAREN BLACK: Let's talk briefly now about the actual process of signing up for a liver transplant.
MICHAEL ABECASSIS, MD: When a patient is evaluated at a transplant center and deemed to be a potential recipient for liver transplantation, then that transplant center will list the patient with a national organization called UNOS, United Network for Organ Sharing. The patient will be listed with this national organization, but they will be listed at a local level. There are 60-odd organ procurement organizations in the country that divide up the country. There are 11 regions. So the 60-odd OPOs, as they are called, would be within these 11 regions.
VAREN BLACK: From the time a patient signs up until the actual time that he gets a liver transplant, how much time are we talking about here on average?
MICHAEL ABECASSIS, MD: The waiting time is a major problem. It depends on a lot of factors, which include the blood type, the severity of illness. To a certain extent, it includes the size of the recipient.
One of the biggest controversies today has to do with the federal government requiring that geography should not be a part of it, and that it should be entirely based on severity of illness. That has been a raging controversy between the transplant community and the federal government.
So to get back to your question about what happens when a patient gets listed. The patient gets listed with UNOS, and then depending on the level of severity, will get an organ allocated whenever their name comes up on this national, computerized list.
VAREN BLACK: We're talking years in some cases?
MICHAEL ABECASSIS, MD: Depending on the severity of illness. If the patient is moribund in the intensive care unit and has less than a week to live, then that patient may get a liver allocated within that week. Oftentimes, the patients will die before a liver becomes available. So in that status, for example, waiting times could be as long as a month.
If patients are stable and have no real need for an urgent liver transplant, the waiting time could be as long as two or three years.
VAREN BLACK: It can be discouraging for some patients, the waiting?
MICHAEL ABECASSIS, MD: It can be discouraging. About 20-30 percent of patients waiting for a liver transplant will die waiting for liver transplant.
