Long-term outcome after liver transplantation in children

Children (defined as under 18 yr of age) account for approximately 12.5% of all liver transplants in the United States. Even though the annual number of liver transplantation procedures remains relatively constant, the population of long-term survivors of liver transplantation has grown. Presently, the population of long-term survivors of liver transplantation is 10-fold greater then the number of transplantations carried out each year. For long-term survivors of liver transplantation, the goal is to maintain graft function and wellness while decreasing the morbidity associated with long-term immunosuppression. The primary diagnosis leading to liver transplantation in children do not recur in the allograft. Consequently, many of the complications of liver transplantation, both early and long term, relate to the need for immunosuppression. Children may be at increased risk to develop significant end-organ damage as a result of increased serum lipid levels elevated blood pressure, altered glucose metabolism, decreased renal function, cancer, and diminished bone accretion that occur as a result of immunosuppressive therapy or complications of therapy. As survival rates have increased, health care providers have begun to assess health-related quality of life. We will review our current knowledge of long-term outcome following pediatric liver transplantation in children.
