Hope Transplant

Bumping along on a Big Wheel tricycle, 4-year-old Garrett LaRue roared out of UCLA Medical Center on Tuesday and pedaled for home, his fragile body cleansed of a rare genetic disorder that probably would have killed him before his 10th birthday.

The Oxnard boy, whose immune system has been wiped out by chemotherapy in the past two months and reborn with a cutting-edge blood cell transplant, was clearly ready to be rid of the hospital. He wanted nothing more than to go home and gobble down a big bowl of his favorite meal: macaroni and cheese.

Garrett may be headed home, but he’s far from home free.

The next few months will be key as doctors carefully monitor Garrett’s progress to see if the blood cells that have been planted in his young body multiply and flourish.

For the boy’s parents, Scott and Theresa LaRue, the waiting is nothing new. Their youngest son, Blayke, successfully underwent the same procedure a year ago to cure the same disorder.

“It’s definitely a different feeling than when we left with Blayke,” said Theresa LaRue, holding 20-month-old Blayke in one arm while a mob of camera crews recorded the family’s departure Tuesday afternoon.

“When we left the first time we knew we would still have to come back with Garrett,” she said. “Now we’re feeling like it’s almost finished.”

It has been a long, hard road to the finish. The boys suffer from a disease known as X-linked lymphoproliferative, a genetic disorder that disables the body’s immune system.

The condition is so rare that only about 300 cases have been reported worldwide since it was discovered in the late 1960s.

Unfortunately for the LaRues, three of those cases involved their sons. In 1995, before they realized their children were carrying the disease, it killed their 13-month-old son, Layne.

Later that year, the LaRues learned that Blayke and Garrett also had the disease, which only afflicts boys and can only be cured with a blood cell transplant.

It was then that the Oxnard couple launched a desperate drive to save their children, scrambling to find suitable bone-marrow donors. The couple eventually settled on a new procedure--similar to a bone-marrow transplant--in which donated blood, rich with stem cells, is given to the patient.

The stem cells, which develop the body’s immune system, come from placental blood extracted from an umbilical cord. By early last year, only about 160 transplants using stored blood from umbilical cords had been done worldwide.

Using a donor from a New York blood bank, doctors at UCLA performed the procedure for their first time on Blayke, completely replacing his compromised immune system last February.

That worked so well that the LaRues decided to try it with Garrett. He underwent the transplant on Jan. 13. “When we saw how well Blayke did we wanted Garrett to have the same chance,” Theresa said. “We were very fortunate to find two matches for our kids.”

Of course, they had plenty of help along the way.

Firefighters at the Alhambra Fire Department, where Scott LaRue is a paramedic, have covered all his shifts for more than a year and raised money for the family. Meanwhile, officers with the Los Angeles Police Department--where the boys’ grandfather, Ron LaRue, is a lieutenant in the North Hollywood Division--helped organize donor drives.

Although donors for both boys were ultimately found outside California, those drives added more than 6,000 names to the national donor bank.

Doctors are hopeful that the transplants will allow both boys to live healthy, normal lives. If Blayke is any indication, there is a good chance of that happening.

When he left the hospital, he was weak and bald from a barrage of chemotherapy leading up to the procedure. Now a toddler, Blayke is alert and has a full head of curly, blond hair. He has just learned to walk and had his catheter removed earlier this month, which means no more drugs.

“I think this has helped us deal with the loss of our son,” Scott LaRue said of the potentially lifesaving treatment administered to his two other boys.

“This is the beginning of a lot of stuff for a whole year, but the hardest part is over.”
