[Somatocrinin induces growth hormone release in a case of growth hormone deficiency of hypothalamic origin in a child].

Somatocrinin (hp-GRF-44), a growth hormone releasing factor, stimulates acute pituitary response in a 11 years and 4 months old boy, with growth hormone deficiency. The capability of the anterior pituitary to secrete growth hormone in response to an IV injection of somatocrinin (120 micrograms 4 micrograms/kg) was documented, therefore proving the hypothalamic origin of the deficit which had been suspected because of association of diabetes insipidus and hyperprolactinemia.
