Somatomedin in growth disorders and chronic renal insufficiency in children.
نویسندگان
چکیده
Somatomedin activity was measured using an embryonic chick cartilage assay in 33 normal and short normal children, 23 children with pituitary growth hormone (GH) deficiency, 14 children with sexual precocity, and 13 children with chronic renal insufficiency. In normal children somatomedin activity correlated well with chronological age: low valles in early childhood rose to higher than adult levels at puberty. Children with GH deficiency had significantly lower activities and those with sexual precocity significantly higher activities than normal children. In all three groups somatomedin activity correlated well with bone age. In children with chornic renal insufficiency there was a significant correlation between decreasing somatomedin activity and both a reduced growth velocity and a falling glomerular filtration rate. Somatomedin activity and growth velocity were within normal limits in children with glomerular filtration rates above 30 ml/min/1-73 m2.

Growth retardation in children with chronic renal insufficiency.
The somatomedins are a family of growth hormone-dependent insulin-like peptides which have been postulated to mediate the actions of pituitary growth hormone on skeletal tissue. The somatomedin peptides are part of a larger family of growth factors. Somatomedin has been measured by bioassays, by radioreceptor assays, and recently by a radioimmunoassay. Bioassays are influenced by glucocorticoid...

Sagliker syndrome is a rare form of renal osteodystrophy resulted from untreated secondary hyperparathyroidism. It is described by severe skeletal deformities, high level of PTH in patients with chronic renal failure, and deformed face. This paper reports a 44-year-old male patient with the mentioned characteristics. In addition to the unique clinical features, high levels of ALP and PTH hormon...
