LIVER CENTER
Diagnosed shortly after
birth,
biliary atresia
Eleanor
doesn’t look sick. She doesn’t act sick either.
Ballet, art lessons and gymnastics occupy regular time slots
on her busy schedule. In a sea of preschoolers, the talkative
4-year-old capped in blonde curls would be the last child
pegged as the one with a mysterious and incurable disease.
Yet each minute of Eleanor’s ballet practice and every day
she spends in preschool bring her closer to her presumable
fate – a liver transplant.
“Eleanor will need a liver transplant before she is in her
teens or early twenties because of her condition,” said
Saul J. Karpen, M.D., Ph.D., chief of service at
Texas Children’s Liver Center
and Biliary Atresia
Clinic at Texas Children’s Hospital.
That condition is biliary atresia, a progressive liver
disease characterized by the liver’s inability to drain
itself of bile. In a healthy liver, bile drains into the
small intestine through a network of tubes and ducts where it
aids in digestion.
With biliary atresia, the ducts and tubes begin to wither and
disappear, trapping bile inside the liver. Without the
ability to drain bile, the liver saturates beyond its
capacity and causes scarring and eventual death of the liver
cells.
Simply put, Eleanor’s liver is slowly poisoning itself.
Two days after Eleanor was born, an alert pediatrician
noticed she was slightly jaundiced; further tests indicated a
more serious condition.
“Biliary atresia in its early stages can be mistaken for
newborn jaundice because of the yellow skin,” explained
Karpen.
However, biliary atresia doesn’t go away – and is fatal if
not properly diagnosed within two months of life. On average,
biliary atresia occurs in one out of every 8,000 to 15,000
live births and affects mostly females; it is the leading
cause of cirrhosis (liver scarring) and the most common
reason for liver transplantation in children. The only
long-term treatment option for biliary atresia is a liver
transplant.
In the United States, approximately 300 to 500 new cases are
reported annually yet its cause remains unknown, said Karpen.
A liver biopsy confirmed the devastating news that Eleanor
had biliary atresia.
“When we asked where to go to get the best treatment – and we
would have gone anywhere in the world – we were told Texas
Children’s Hospital," said Eleanor’s mother, Harriet.
“Fortunately for us, it was in our backyard.”
At six weeks old, Eleanor underwent the Kasai surgical
procedure to attach the small intestine to the liver to drain
the excess bile. The Kasai procedure isn’t a cure – just a
potential way to keep the disease from progressing. It
successfully slows the effects of biliary atresia in about 80
percent of children who undergo the procedure, said Karpen.
Four years after her Kasai procedure, Eleanor lives a normal
life. Her biliary atresia still slowly progresses, but her
parents and physicians carefully manage it.
In spite of all preventive care, Eleanor’s liver continues to
harden and develop scar tissue. When scar tissue develops to
a certain point, explained Karpen, the liver can no longer
function.
For children like Eleanor, a liver transplant is the closest
thing to a cure.
Eleanor will receive her liver transplant when keeping her
own liver is more dangerous to her health than surgery to
receive a new one, Karpen said.
As a national leader in liver transplants, Texas Children’s
Liver Center survival rates rank among the nation’s best at
94 percent. The national average is 85 percent, according to
John Goss, M.D., director of pediatric liver transplant
service at Texas Children’s Liver Center and associate
professor of liver transplant surgery at Baylor College of
Medicine.
Next to the skin, the liver is the human body’s largest
organ. From its perch just under the diaphragm, on the right
side of the abdomen, the liver is the body’s “multi-tasker,”
performing more than 500 functions including:
-
Cleansing the blood of poisons and
waste.
-
Synthesizing important proteins
contained in blood plasma, including clotting agents and some
antibodies.
-
Producing globin, one of two
components of hemoglobin, the substance that allows red blood
cells to carry oxygen.
-
Regulating the levels of many
chemicals found in the blood.
-
Storing reserves of vitamins and
nutrients.
-
Producing bile, a key fluid in the
digestion of fats.
-
Regulating water distribution
between the blood and tissues.
-
Storing and releasing energy in the
form of glucose, the key blood sugar that fuels our cells.
