  • Title: Effect of chronic renal failure and prednisolone on the growth hormone-insulin-like growth factor axis.
    Author: Kapila P, Jones J, Rees L.
    Journal: Pediatr Nephrol; 2001 Dec; 16(12):1099-104. PubMed ID: 11793109.
    Abstract:
    Abnormalities of the growth hormone (GH)/ insulin-like growth factor (IGF) axis have been reported in children with chronic renal failure (CRF) and post-transplant, and are thought to contribute to poor growth. This study examined the effect of CRF and steroid therapy (given post-transplant and to children with normal renal function) on the GH-IGF axis in children with normal and abnormal growth. Thirty-one children with CRF, ten on dialysis, 26 with renal transplants and ten taking steroid therapy but with normal renal function, were studied. IGF-I, measured by radioimmunoassay, was normal but IGF bioactivity was low in groups with a decreased glomerular filtration rate (P<0.05). Transplanted children growing at a subnormal growth rate had lower IGF bioactivity than those growing at a normal rate (P=0.03), but there was no such difference in bioactivity in children with CRF. There was no correlation between IGF bioactivity and prednisolone treatment. There was no correlation between IGF binding proteins 1, 2 or 3 and growth.
