Will Any Organ Do?

By GRETCHEN REYNOLDS
Last summer at one hospital in Dallas, four people died from rabies,
an unheard-of level of incidence of this rare disease. As it turned
out, each patient was infected by an organ or tissue -- a kidney, a
liver, an artery -- that he or she received in a transplant several
weeks earlier. Their shared donor, William Beed Jr., a young
brain-dead man, had rabies, caught apparently through a bite from a
rabid bat, something the surgeons never suspected. They all thought he
had suffered a fatal crack-cocaine overdose, which can produce
symptoms similar to those of rabies. ''We had an explanation for his
condition,'' says Dr. Goran Klintmalm, a surgeon who oversees
transplantation at Baylor University Medical Center, where the
transplants occurred. ''He'd recently smoked crack cocaine. He'd
hemorrhaged around the brain. He'd died. That was all we needed to
know.''
Since the rabies deaths, recriminations have flown, procedural reviews
have begun and sorrow and regret have dogged the families of the organ
recipients. But the outbreak also exposed a controversy that until
then was roiling only the rarefied world of transplant specialists.
The issue, although freighted with monetary and bio-ethical
complexities, can be boiled down to one deceptively simple question.
Should transplant surgeons be using organs from nearly anyone?
Organ transplanting has become, in fundamental ways, a victim of its
own success. Not long ago, transplant surgery was a dodgy, last-ditch
response to end-stage kidney failure. But with the advent of better
antirejection drugs and surgical techniques, transplantation has
become the treatment of choice for a growing range of conditions,
including chronic kidney failure, end-stage lung or liver disease and
some congestive heart failure. Kidneys are implanted routinely, as are
increasing numbers of livers, hearts and pancreases.
Fifteen years ago, about 20,000 people in the United States were on
waiting lists for organs. Today, about 88,000 are. The number of
donors has not come close to keeping pace. There were about 15,000
transplants completed with organs from cadavers in 1993 and about
20,000 last year. Patients used to wait weeks for an organ. Now they
wait years. On average, 18 people on organ waiting lists die every
day.
Doctors, patients and politicians concerned about transplantation have
responded with proposals for increasing donations. In 2002, the
American Medical Association voted to endorse pilot projects to give
families financial incentives, like cash payments to help cover the
costs of funerals, for donating their deceased loved ones' organs. The
next year, Congress held hearings on the topic. Representative James
Greenwood, Republican of Pennsylvania, introduced a bill that would
have authorized demonstration projects to determine whether offering
financial incentives to families of brain-dead patients would increase
donation rates. There was a public outcry against ''buying'' organs
and the bill died. (A few states offer tax incentives to families who
donate relatives' organs.)
Increasingly desperate people in need of transplants have turned to
highway billboards and Internet sites to solicit donors. Donations
from living people have helped. Today the number of living kidney
donors is greater than the number of dead donors. But living donations
of other organs are rare because they can be dangerous or are
impossible.
All of which has led transplant specialists to quietly begin to relax
the standards of who can donate. As a result, according to surgeons I
spoke with and reports in medical journals, the transplanting of what
doctors refer to as ''marginal'' or ''extended criteria'' organs,
organs that once would have been considered unusable, has increased
considerably in the last several years. The definition of a marginal
organ differs from transplant center to transplant center and also
from one type of organ to another. This makes it difficult to quantify
the increase in the use of these organs. But the expansion is
undeniable and has become a much-discussed issue in the field, a topic
of ethics papers, surgical conferences and soul-searching on the part
of many of the surgeons involved.
Fifteen years ago, William Beed Jr. would not have qualified as an
organ donor. When he died in May 2004, he was 20, unemployed and had
been living with his mother and sister in a bat-infested apartment
building in Texarkana, Ark. Throughout his life, Beed had been in and
out of trouble, his mother acknowledged when I spoke to her recently.
Marijuana and cocaine were found in his urine at the time of his
death, according to a report in The New England Journal of Medicine.
Beed's drug use alone would have disqualified him as a donor. (It
still would keep him from giving blood.) ''What people have to
understand is that donors now, except for the 75-year-olds who die of
intracranial bleeds, are not part of the church choir,'' Klintmalm
told me when I met with him in Dallas earlier this year. ''The ones
who die are the ones you don't want your daughter or your son to
socialize with. They drink. They drive too fast. They use crack
cocaine. They get caught up in drive-bys.''
The donor pool was different in the early days of transplantation.
Beginning in the 60's and through the 80's, a majority of donors were
head-trauma victims, people who had been involved in car accidents,
botched suicides or tumbles off horses or ladders. These donors were
almost all young, between 15 and 45. (In the 80's, few transplant
surgeons would take a 50-year-old organ.) They were of average weight,
with no history of diabetes, cancer, infectious disease, imprisonment,
high blood pressure, cigarette-smoking habits, tattoos (which have
been associated with blood-borne illnesses) or unsafe sexual
behaviors. The chosen organs, said Klintmalm, who has been in practice
for about 25 years, ''were pristine.''
It was easy to adhere to those standards at first. ''We didn't
perceive any shortage of organs back in the day,'' says Dr. Nicholas
Tilney, the Francis D. Moore professor of surgery at Harvard Medical
School and one of the nation's premier kidney-transplant surgeons.
''If a patient had to wait a few weeks for a kidney, that seemed long.
We never foresaw the kind of situation we have today.''
Conditions began to change in the 90's. Seat-belt use was more common
by then, and fewer Americans were dying of head injuries, depriving
transplantation of its most reliable sources of pristine organs. At
the same time, the demand for transplants was growing. Surgeons had
little choice but to start looking to alternative sources for organs.
On April 28, 2004, William Beed Jr. complained to his mother that he
was feeling sick. ''He couldn't swallow,'' his mother, Judy, a
practical nurse, recalled when I spoke with her earlier this year.
They decided he should go to an emergency room, she said, and the
doctors there examined him and sent him home with medication, saying
he was dehydrated. By that evening, he was drooling, throwing up,
shaking and still having difficulty swallowing. His fever was rising.
He started vomiting blood. His father drove him to another E.R.
Diagnosis is often a matter of context. Because of doctor-patient
confidentiality rules, doctors involved with this case would not talk
about it on the record, but a few did say that had Beed not had
cocaine in his blood, the E.R. doctors might have investigated his
symptoms more aggressively instead of assuming he had overdosed.
(Because no autopsy was done, doctors have not been able to establish
whether the rabies or the drugs actually killed him.)
Soon after, Beed fell into a coma and was put on a ventilator. After a
few days, his mother said, the doctors told her and her family that
their son was brain-dead. Transplant surgeons use organs from
brain-dead patients because they still have a heartbeat, and if the
patients are placed on a ventilator, their organs continue to get
oxygen. Without oxygen, the organs degrade within minutes.
According to Judy Beed, a transplant coordinator approached her and
asked whether she would be willing to donate her son's organs. She
agreed, and in the middle of the night on May 4, the parents of Joshua
Hightower received a phone call offering them William Beed's kidney.
Joshua Hightower, who lived in Gilmer, Tex., had had kidney problems
since he was 2. They had grown progressively worse over the years.
''When he was 16, things got really bad,'' said his mother, Jennifer
Hightower, a special education assistant in the public schools, when I
met with her in February. ''He was pale and droopy. He weighed 112
pounds. He was sleeping all the time.'' His teachers at Gilmer High
School walked him up and down the halls between classes to help him
stay awake. A doctor urged his parents to get him on the waiting list
for a kidney. In the meantime, Joshua began daily dialysis at home.
The process, which purified his blood of toxins, required that he be
home every evening by 10. Once there, he was tethered to the dialysis
machine for between 9 and 16 hours. When the Hightowers received the
call from the hospital, they jumped at the opportunity.
It is impossible to know now when the first less-than-pristine organ
was retrieved and transplanted. But over the course of the 90's,
according to surgeons I spoke with, many barriers fell. Age was almost
certainly the first to go. Instead of accepting donors 45 and younger,
some transplant centers began, gradually, to take those who were 48,
49, 50 and then up from there. ''I wrote a paper for The Journal of
the American Medical Association back in 1989,'' Dr. Lewis Teperman,
director of transplantation at New York University Medical Center,
told me when I talked to him earlier in the spring. ''It was looking
at the outcomes of using older donors. By older donors, we meant
someone over 60. That was considered really, really old.'' Recently,
N.Y.U. transplanted a liver from a deceased 80-year-old. A couple of
years ago, a Canadian hospital used a 93-year-old liver from a
deceased donor.
Almost imperceptibly, most of the other traditional prohibitions
evaporated. Surgeons started accepting lungs from people who had
smoked, sometimes for decades. They accepted hearts and kidneys from
those who had had high blood pressure or had been obese. They took
organs from alcoholics and drug users. (Because cocaine is flushed
from the body relatively quickly, it is considered one of the least
problematic drugs in donors.) Infectious disease was no longer an
automatic disqualifier, either. Most surgeons would have once
discarded organs from someone with hepatitis C, for instance, since it
destroys the liver. But the virus, often spread by injected drug use,
is now so common in urban areas that few transplant surgeons will
immediately turn down an organ infected with it. Ideally the surgeons
implant these infected organs into patients who already harbor
hepatitis C. But lately there have been cases in which doctors, as a
last resort, have transplanted infected livers into patients who don't
have hepatitis C. There is little published data yet about the
long-term outcomes for these patients.
The expansion into ''marginal'' or ''extended criteria'' organs has
not been systematic. One transplant surgeon will use a marginal organ
from, say, a morbidly obese donor or a drug user. His patient
survives. Then he will repeat it again and again. At the next big
transplant conference, he will talk to his colleagues about his
success, and they will go back to their own transplant centers and
accept, for the first time, an obese donor or a crack-cocaine user.
''You sometimes have to experiment,'' Klintmalm says.
Klintmalm and other surgeons I spoke with who work in urban areas say
that marginal organs are well on their way to being the majority of
organs they transplant. Klintmalm, though, takes issue with the very
definition of marginal. ''Older organs should not be called
'marginal,''' Klintmalm maintains, referring to donors over age 55.
''They're standard for us.'' But two years ago, when the United
Network for Organ Sharing (UNOS), the private organization that
oversees organ transplantation in the United States, published its
first definition of extended-criteria organs, age was prominent. The
UNOS classification, which applies only to kidneys, defines a marginal
kidney as one that comes from a deceased person over 60 or one over 50
with two of three characteristics: stroke, hypertension or abnormal
kidney function. The definition does not mention smoking, diabetes,
hepatitis, alcoholism, obesity or drug use.
No government agency sets standards for what makes an organ
acceptable. The Department of Health and Human Services contracts with
UNOS to handle the day-to-day logistics of the transplant system
(getting organs to the next person on the list and so on). But the
government's main concerns in policing transplants are that donors and
recipients be matched for blood type and that organs be distributed
primarily based on medical need, not the wealth, race or celebrity of
the recipients. So decisions about whether organs are usable are made
on the spot by individual surgeons.
To date, not many peer-reviewed studies have been published that
examine the long-term outcomes of using marginal organs. The research
that has been done mostly looks at kidneys.
Recent studies of older kidneys (usually defined as over 50), for
instance, have shown that they can function almost as well as younger
ones. They don't work for as long, however. In a report presented by
UNOS, which adjusted for the health of the recipient, among other
things, about a third of extended-criteria kidneys failed within three
years. (About 20 percent of non-extended-criteria organs also failed
within three years.) Transplantation, even under the best of
circumstances, still involves risk. In assessing marginal organs, it
is difficult to know whether a bad outcome -- the recipient's death or
the organ's failure -- was caused by the organ, the surgery or the
fragile health of the recipient.
Except for age-related research, few large-scale studies have yet
investigated the effects of other extended-criteria kidneys. Do
kidneys from diabetics, the obese, alcoholics, smokers or drug users
generally work over the long term? Surgeons and scientists can't say
for sure.
There is even less information about imperfect livers, hearts or
lungs. Surgeons do know that livers, for some reason, don't age at the
same rate as their original owners. Sixty- or 70-year-old livers can
be in fine shape. Hearts and lungs aren't as durable and are more
likely to fail as they get older. But surgeons are using them. A 2003
report by the UNOS-administered Organ Procurement and Transplantation
Network stated: ''The need to more agressively utilize available
organs for the candidate population as a whole competes with the
expectation of each individual.''
And this is, ultimately, the crux of the matter. The marginality of
any given organ is relative. It depends on how sick the waiting
recipient is. There is a kind of mad, desperate arithmetic that goes
into calculating whether to use a marginal organ and when. ''We're all
trying to quantify the risks,'' Lewis Teperman, the N.Y.U. transplant
director, says. ''If we know that there's a 0.7 increase in relative
risk of an extended-criteria organ failing, which is about what we've
seen in kidneys so far, you take that number, look at your patient's
chances for survival, which might be 90 percent with a perfect organ
and 80 percent with an extended-criteria one and. . . . '' He trails
off. ''It sounds very clinical when I put it like that, which isn't
what I want.'' He starts again. ''It's easy enough to come up with
these kinds of calculations. But it's difficult for any of us to apply
them in practice, when we're dealing with very sick people's lives.''
Dr. Marlon Levy, a liver-transplant surgeon in Fort Worth and the
medical director for the Southwest Transplant Alliance, the group that
unwittingly collected and distributed the rabid organs last year, told
me: ''You have this immensely complex weighing of benefits and risks
in each of these cases. Is the recipient sick enough to justify using
any organ, even a really marginal one, to try and save his life and
give him a few more years? Or say you have a slightly healthier
patient, and you think he's doing well enough to pass on a marginal
organ and wait for a better one. Then, suddenly, he develops
complications and dies before another organ becomes available. Were
these decisions wrong?''
It is extremely difficult to predict outcomes. ''The best thought-out
decision doesn't work out all the time,'' Teperman says. ''I have put
in extended-criteria organs that worked perfectly, and the person
walked out the door a week later. Other times, a patient has gotten an
extended-criteria organ and remained hospitalized for months. I've
also waited, thinking a better organ would come along, and the patient
has died in the meantime.''
To some extent, surgeons' hands are tied. In general, the current
system requires that the most desperately ill patient must get the
next organ that comes in, whether it is the best organ for that
patient or not. ''Things would work best if we could put the most
extended-criteria organs into the less critically ill patients and the
healthiest organs into the sickest patients,'' Teperman says.
The calculus may be even more complex from the patient's perspective.
Dr. Grant Campbell, an epidemiologist with the Centers for Disease
Control and Prevention, had a liver transplant in 1990. At that time,
he was chronically ill and knowingly accepted an organ infected with
cytomegalovirus, a common and usually mild disease but one that can be
serious in immunosuppressed transplant patients. Fortunately, he
didn't become sick.
Even the most rational attempts to weigh the risks and benefits of
marginal organs tend to fall apart in the face of truly boundless
human despair. ''We would have taken any lungs,'' said Harry
Littlejohn, 59, of Lewisville, Tex., whose 28-year-old daughter,
Carmen, died in 2001 of cystic fibrosis. She had been No. 1 on the
state waiting list for new lungs for eight weeks by then. None became
available. ''We would have done anything to save her,'' he said,
''anything. But there was nothing we could do.''
Joshua Hightower turned 18 on May 10, 2004, in the transplant recovery
ward at Baylor University Medical Center. Photos from around that time
show him propped up in bed, looking wan, but smiling.
Joshua had been added to the lengthy transplant waiting list the year
before. The doctors said they could not estimate how long the wait
would be, Jennifer Hightower, his mother, told me.
After the Hightowers received the call from the hospital, his mother
recalled, she had wondered about the donor. Anonymity has been crucial
to the workings of the organ-transplant system. Donation is supposed
to be a blind act of altruism. Donor families aren't told at the time
who will receive the organs, and recipients generally are told only
the age and sex of the donor.
''You don't want people coming in and saying, 'I'll only donate to
Italians.' Or 'I only want them to go to someone in the Ku Klux
Klan,''' says Sheldon Zink, director of the program for transplant
policy and ethics at the University of Pennsylvania. You also don't
want recipients turning down organs because of their own biases.
But how much should a surgeon tell a patient who is about to receive a
compromised organ? Should he explain that the new kidney comes from a
retiree, a drug user or an alcoholic, a chain smoker or a member of a
motorcycle gang? Does he have to tell a patient that the organ he is
about to receive is considered marginal?
"I wish we had been told more,'' Jennifer Hightower says. Her son, she
went on to say, would have declined the kidney had they known more
about Beed's background and his death. Joshua, she says, was not so
sick that he couldn't wait. ''I would have made him pass on it.''
Her attitude worries Zink, the ethicist. ''I would question anyone's
motivation in refusing an organ from a drug user,'' she told me.
''They aren't responding to clinical information, because the
available clinical data'' -- the anecdotal reports from doctors --
''indicates that organs from crack-cocaine users are fine, in general.
So they must be responding to preconceptions about that person's
lifestyle. That's only one small step from declining an organ because
the donor is black or Hispanic.''
At the moment, no formal national medical standards dictate what
transplant surgeons should tell their patients about organs other than
kidneys or what they can withhold. Each doctor makes that decision
based on how he feels about the ethics of the situation.
''I believe in erring on the side of telling the patient as much as
possible,'' Teperman says. ''We have a lengthy consent form here at
N.Y.U., and it goes into the use of marginal organs. We ask patients
if they will accept one. You don't want to be calling someone at 2
a.m. and saying: 'You can take this organ we just got in that may not
be very good or you can wait and maybe die. What do you want to do?'
That's an unrealistic burden to put on a patient. We try to have the
conversation early on, when patients are a little more clearheaded.
That's not always an easy conversation to have. Some patients would
rather not think about it. They'd rather the doctor just make the
decision for them.''
Some surgeons insist on making decisions about marginal organs
unilaterally. ''There are transplant surgeons who think they
absolutely know best,'' Zink says. ''They don't bother asking the
patient if he wants a marginal organ because they don't want the
patient having a choice. They make it for him.''
When Zink recently asked surgeons at a major transplant conference how
many of them always tell their patients if they are about to implant a
marginal organ, ''about half said they tell the patient,'' Zink told
me. ''Half said they don't.''
Some surgeons withhold information because they are concerned about
litigation (better to say nothing than to say that an organ might be
compromised, have your judgment proved right and be sued for it).
Others are prodded by compassion. ''There are doctors out there who
think that a patient will recover better if he isn't worrying about
the quality of the organ inside of him,'' Zink says.
Wry pragmatism also plays a role. ''At some large urban transplant
centers, virtually all organs nowadays are extended-criteria organs,''
Zink points out. Why discuss the option of accepting or declining an
imperfect organ? If a patient says he doesn't want one, he'll most
likely never get an organ at all. ''I've had doctors tell me they
don't even tell their patients that they're about to get an organ that
might be infected with hepatitis C because so many of the donated
organs may have it,'' Zink says.
On Friday, May 28, 24 days after his transplant, Joshua Hightower, who
had been released from the hospital, graduated from high school. He
clutched his diploma, climbed up into the stands and threw up,
Jennifer Hightower said. He didn't stop vomiting all through the
celebrations that followed. The next day, he was stumbling, and by the
evening, he was having convulsions. Spit dribbled down his face.
Doctors at the nearest emergency room hurriedly transferred him to the
E.R. at Baylor.
Upstairs in the transplant wing, around the same time, three other
patients who had received donations from William Beed Jr. lay dying,
each with convulsions, delirium or pain. Within two weeks, all but
Joshua were dead. Rabies was confirmed as the cause of death a few
weeks later.
There is no formal system that tracks the short-term fate of
individual organs from a particular donor. Surgeons report raw data
about deaths and severe surgical complications to UNOS. Had all of the
people who received an organ from William Beed Jr. not come back to
the same hospital and died, one after another, their rabies may not
have come to light.
In May, three people died who had received organs from the same donor
in New England. As it turned out, the donor had passed along
lymphocytic choriomeningitis virus, a rare illness transmitted to
humans from rodents like hamsters. Two of the recipients, after
getting ill, went to the same hospital, which helped doctors there
determine that the transplant was the cause.
''I doubt very much that this is the only time'' that rabies has
killed transplant patients, says Charles Rupprecht, the C.D.C.'s
rabies expert about the Beed case. ''And I doubt that it will be the
last.'' In February, doctors in Germany announced that four patients
there had been infected with rabies after receiving organs from a
rabid young woman who had died, they had thought, of a heart attack
associated with an overdose of cocaine and Ecstasy.
''Rabies is a sentinel disease,'' argues Dr. Matthew Kuehnert, the
assistant director for blood safety at the C.D.C., who has studied
outbreaks of disease in transplant recipients. ''It tells us we should
be paying attention, that something needs to change.''
What, though? ''We cannot start testing every donor for rabies or any
of the other once-in-a-lifetime diseases that might crop up,''
Klintmalm says. ''We don't have time. It would cost too much. You
might as well shut down every transplant center. If another case came
in today exactly like that one, a young man who used crack cocaine and
died, I would not demand more explanation. Why? We'll never get the
risk of transplants down to zero. It's stupid to pretend we can. That
young man appeared to be a perfect donor. I wish we had more like
him.''
The broader question is what, if anything, should change in
transplantation as marginal organs become everyday organs? ''We at the
C.D.C. wish that there were more formal disease surveillance and
follow-up of transplant patients,'' Kuehnert said. ''We simply don't
know the risks of using certain types of donors at this point.'' The
C.D.C. has no authority to require such follow-up and study, though.
Only other regulatory agencies within the Department of Health and
Human Services or state agencies can set such mandates.
In June 2004, the New York State Department of Health became the first
regulatory agency in the country to start formally looking into the
growing use of marginal organs and to formulate recommendations about
what patients should be told and what kinds of organs should be
allowed. Its report is due soon.
In the meantime, the United Network for Organ Sharing has created a
designation for patients who say they will accept a marginal kidney.
At the end of February, 42 percent of the adults waiting for a kidney
in the United States said they would take a marginal organ.
A year ago, while Joshua Hightower lay unconscious but alive, the
doctors decided to surgically remove his transplanted kidney. But by
then, rabies (not yet identified as the culprit) was everywhere in
him. His condition worsened. On June 18, a Friday, doctors tested for
brain activity. They found none and declared him brain dead. Stung
with grief, Jennifer Hightower and the rest of her family sat with the
boy through a wrenching weekend while he remained on a ventilator. On
that Monday, his parents agreed to end life support. That afternoon,
with his family watching, doctors turned off the ventilator. His
mother held him as his heart stopped.
It will not be a simple matter in the years ahead to decide how best
to save lives with transplants. At some point this year, the number of
people on transplant waiting lists in the United States will very
likely top 100,000. Unless there is an enormous effort, probably from
the federal government, to increase organ donation, the shortage will
only grow. ''All these kids we see with diabetes,'' Nicholas Tilney
says, ''so many of them will need a new kidney in a few years. Where
are those organs going to come from?''

article for the magazine was about epidemiologists tracking the avian
flu.
