Should parents pay a blood bank to hive away the blood from their newborn babe & # 8217 ; s

umbilical cord and placenta, in instance that kid or another household member of all time

demands it to handle malignant neoplastic disease or leukaemia? Anticipant parents are being urged to make so

by companies that have sprung up during the past few old ages to sell cord-blood

banking as a signifier of “ biological insurance ” against such awful

diseases. The pitch is based on studies in medical diaries, such as a major

survey published last hebdomad in the New England Journal of Medicine, demoing that

cord blood can sometimes be used in topographic point of a bone marrow graft. Like bone

marrow, cord blood is rich in root cells, which can churn out many different

types of cells to reconstruct a patient & # 8217 ; s blood supply and immune system after high

doses of radiation and chemotherapy.

And a patient & # 8217 ; s ain cord blood, or that

from a comparative, is more likely than cord blood from an unrelated giver to be a

good tissue lucifer and to be accepted by the receiver & # 8217 ; s organic structure. Some experts in

bone-marrow organ transplant and blood banking scowl on the cord-blood concern,

reasoning that people are being frightened into blowing money on a service they

will likely ne’er necessitate. Furthermore, private companies are turning in tandem with

public Bankss, and some scientists worry that private banking will restrict public

entree to cord blood. They are concerned because the cord blood in private Bankss

remains the belongings of the donor household and is non available to patients

seeking a compatible giver. But the companies say that nevertheless remote the

possibility that the blood will be needed, people who choose to bank their ain

cord blood have a right to make so. In most instances their cord blood would be thrown

off in the bringing room if they did non pay to bank it. There are merely a few

cord-blood Bankss in the United States, and most infirmaries do non hold specially

trained staff members to roll up the blood. Like bone marrow, cord blood must be

matched to the receiver by trials for six familial traits that determine an

single & # 8217 ; s tissue type. Cord blood does non hold to be as exactly matched as

bone marrow, but still, the closer the lucifer, the better the odds of success.

The weaker the lucifer, the more likely it is that the receiver & # 8217 ; s organic structure will

reject the graft, or the graft will assail the receiver & # 8217 ; s tissues, in

a dangerous reaction called transplant versus host disease. The companies that

freezing cord blood and bank it point out that a individual & # 8217 ; s ain cord blood is a

perfect lucifer, and a sibling & # 8217 ; s cord blood a more likely lucifer than a specimen

from a alien. And so, the statement goes, the best manner to protect an full

household from the unthinkable is to salvage the neonates & # 8217 ; cord blood. Promotional

literature for one company, Cord Blood Registry, in San Bruno, Calif. ,

emphasizes that people with malignant neoplastic disease in the household may hold a particular involvement in

cord-blood banking, along with those who have the hardest clip happening lucifers,

which includes members of racial minorities, particularly households in which the

parents are of different races. Harmonizing to a spokeswoman, Scoti Kaesshaefer,

the company reaches parents-to-be by advancing itself to physicians, nurses and

childbearing pedagogues, and by go forthing information at infirmaries. Among the

promotional stuffs the company provided to the New York Times were transcripts of

articles from other newspapers proposing that malignant neoplastic disease among kids is on the

rise. The company besides has a Web site and an 800 figure with a recorded salutation

that instructs companies to hold their recognition cards ready. The thought of salvaging

one & # 8217 ; s ain cord blood seems to be catching on. Cord Blood Registry, which

describes itself as the largest private cord-blood banking house in the United

States, has stored 10,000 samples during the past three old ages: 1,500 in 1995,

R / & gt ;

3,000 in 1996 and 6,000 in 1997. The company charges an initial fee of $ 1,200 to

roll up a sample and freezing it, and so $ 95 a twelvemonth to maintain it stored in liquid

N at the blood bank at the University of Arizona. Customers include

people with absolutely healthy kids, who merely want excess peace of head, as

good as some households who have lost a kid to leukemia or another disease and

fright for the wellness of their other kids. In its three old ages of operation,

eight clients have retrieved their cord blood for usage in medical intervention,

said Kaesshaefer. All eight samples were used for siblings or relations, she

said. By contrast, the largest public-access bank of cord blood, at the New York

Blood Center in Manhattan, has collected merely 8,686 specimens in six old ages. But

about 800 of those samples have been used to handle patients, many of them

kids, in the United States and overseas. Critics of private cord-blood

companies point out that even if a individual with banked cord blood does necessitate a

graft later, the stored blood may non be the best pick. Dr. Pablo

Rubinstein, who directs the cord-blood plan at the New York Blood Center,

said there was a compelling medical statement against utilizing a patient & # 8217 ; s ain cord

blood in some instances. In some immature kids with leukaemia, he said, malignant

cells were already present at birth in the cord blood, and instilling those

cells back into the kid subsequently might lend to a backsliding. In add-on, he

said, bone marrow from a giver could assist destruct morbid cells, an consequence

known as transplant versus leukaemia. A individual & # 8217 ; s ain cord blood might non hold that

consequence, and in some instances even a sibling & # 8217 ; s might non. Dr. John Wagner, associate

manager of bone marrow organ transplant at the University of Minnesota in

Minneapolis, said that for a kid being treated late, he intentionally

rejected cord blood from a sibling in favour of a well-matched unit from an

unrelated giver, trusting to take advantage of its antileukemic consequence. Dr.

Robertson Parkman, manager of bone marrow organ transplant at Children & # 8217 ; s

Hospital in Los Angeles, said he saw no point in banking cord blood for most

households. “ It & # 8217 ; s motivated by fright, ” he said. But in households with an

sick kid who might necessitate a bone-marrow graft, he said, it makes sense to

collect cord blood from any siblings born subsequently and salvage it. Medical centres

with transplant plans will frequently execute that service, he said. So will some

of the private companies, without a fee. When a bone-marrow giver could non be

found for 4-year-old Joshua Kelton, who was enduring from leukaemia, his

parents, stationed at a military base in Honolulu, conceived another kid in

the hope that the babe & # 8217 ; s tissues would fit Joshua & # 8217 ; s. They did, and Cord Blood

Register collected the cord blood at birth, stored it in Arizona for a month,

and so, when Joshua was ready for the process, transported it to a medical

centre at Stanford University. Joshua was treated with his baby brother & # 8217 ; s cord

blood in August, and has been declared free of leukaemia. “ Right now, he & # 8217 ; s

100 per centum, ” his male parent said in a telephone interview, “ a normal

kid, the manner he was before this happened. ” But the Keltons & # 8217 ; experience is

barely representative. That the household was certain it would necessitate the cord blood

sets it apart from most households that store the blood. Wagner is wary of the

hard sell of some of the cord-blood companies. “ My concern is that it be

presented reasonably to expectant female parents, who are already reasonably vulnerable, ”

he said. “ I have a batch of accoucheurs and parents naming me and

kicking it & # 8217 ; s excessively late, they missed the chance. Others call stating,

& # 8216 ; Should I make this? & # 8217 ; It & # 8217 ; s difficult to reply. I don & # 8217 ; t want to bias them. We have

person now who takes the calls for me because it got to be overpowering. ”
