INSULIN-LIKE GROWTH FACTOR-1 AFTER ORTHOTOPIC LIVER TRANSPLANTATION IN CHILDREN WITH CONGENITAL AND HEREDITARY DISEASES OF HEPATOBILIARY SYSTEM

Abstract

The research of total and free insulin-like growth factor-1 (IGF-1) in 53 children with with congenital and hereditary diseases of hepatobiliary system was performed before liver transplantation, a month and a year after liver transplantation. Data of our research work revealed reliable decrease of total and free IGF-1 serum concentrations in children with liver cirrhosis and controversy increase of PAPP-A, which regulates IGF-1 bioavailability. In a month after orthotopic liver transplantation the level of both fractions of IGF-1 restored. A year later concentrations of total and free IGF-1, and PAPP-A remained at normal rates. Increase of total and free IGF-1 after liver transplantation may contribute to restoration of endocrine regulation of growth, reparative and anabolic processes, and normal physical development of children.
