title: The hypothalamo-pituitary-growth hormone insulin-like growth factor 1 axis in children with chronic renal failure.
abstract: Growth hormone (GH) levels are high in children with chronic renal failure (CRF), and there is increased hypothalamic sensitivity to the factors that normally modulate GH secretion. GH binding protein (GHBP) is decreased, which may reflect decreased GH receptor activity. IGFBP3 levels are normal in both CRF and transplanted children when measured by immunoradiometric assay, but intact IGFBP3 is low in transplanted children with an excess of small fragments, measured by Western immunoblotting. These fragments may interfere with IGF1 bioactivity.
