title: Combined test of hypothalamic-pituitary function in growth-retarded children treated with growth hormone. II. Secretion of LH, FSH, TSH, prolactin and ACTH.
abstract: A total number of 23 patients treated with human growth hormone were retested by use of a combined pituitary stimulation test. Plasma concentrations of GH, FSH, LH, TSH, T4, T3, prolactin (PRL), ACTH and cortisol were measured before and after stimulation with hypoglycemia, TRH and LHRH. The test was performed in patients with persistent GH deficiency (group A) and patients with transitory GH deficiency (group B). In group A a normal pubertal development was found in three patients, whereas in prepubertal subjects the FSH/LH responses were smaller than those of prepubertal patients in group B. Also plasma ACTH increase was less pronounced in group A patients than in group B. In contrast, the plasma TSH and PRL responses were more sustained in group A than in group B. The secretory pattern of TSH and PRL was comparable in the two groups of patients. Thus, in patients with persistent GH deficiency additional multiple disturbances of the hypothalamic-pituitary function often appeared whereas in most patients with transitory GH deficiency the combined pituitary test was normal at the reinvestigation.
