Aiden and Miles Blomgren are thriving following their liver transplants.

In this file photo from Jan. 4, 2001, two-year-old Miles Blomgren plays with his parents Dan and Jill Blomgren while recovering from a Nov. 2000 transplant operation where he received part of his father's liver.

Miles Blomgren, 10, and his brother, Aiden, 7, are growing by leaps and bounds and are always ready for a new adventure.

That’s pretty typical for boys.

But what makes the Blomgren brothers special is that they have overcome progressive familial intrahepatic cholestasis, an inherited disease that causes progressive jaundice and scarring of the liver.

As toddlers, they were jaundiced, scrawny and couldn’t jump or run.

Both boys received liver transplants at Children’s Memorial Hospital in Chicago. At age 2, Miles received a portion of his dad’s liver. The surgery came in the nick of time because Miles’ original liver was cancerous and had they waited, the cancer might have spread.

At age 3, Aiden received a liver from someone’s deceased loved one. His parents, Dan and Jill, are forever grateful, especially because neither of them were a match for Aiden.

Four years later, the boys are as energetic as ever.

“They wear me out,” Jill said, laughing.

Miles is participating in a groundbreaking study where living donor recipients are gradually taken off anti-rejection drugs. He took his last anti-rejection medicine — which can cause nasty side effects — on Dec. 26, 2007. A year ago, he was getting lab work done every two weeks. Now, he goes in once a month. Aiden’s medications have been significantly reduced since his surgery.

Both have been getting a good bill of health during checkups in Chicago. Jill described the family as happy, energetic and doing great.

Aiden has taken to playing soccer. Meanwhile, Miles like to dabble in a bunch of sports. They still love on their dog, Cocoa, a brown miniature Labradoodle.

“We’ve had no problems at all,” she said. “Life is great.”
