In a previous study we demonstrated that, in children affected with isolated GH deficiency, an acute high-dose human recombinant GH (hrGH) treatment increases the 11-deoxycortisol and induces an IGF-I responsiveness to ACTH. The aim of the present study was to reevaluate, in the same children, the adrenal and IGF-I responsiveness to ACTH after a chronic replacement-dose GH therapy. Ten children (seven males and three females, mean age 7 years) affected with isolated GH deficiency underwent a synthetic ACTH 1-17 test before and after sc administration of human recombinant GH at a dose of 0.6 UI/kg/week for 3 months. After therapy, the 11-deoxycortisol responsiveness to ACTH significantly decreased compared with that observed after acute treatment (P < 0.001), and so it returned to baseline. No differences were detected in the responsiveness to ACTH of cortisol, dehydroepiandrosterone-sulphate, D4-androstenedione, and 17-hydroxyprogesterone. On the other hand, the chronic treatment induced an IGF-I responsiveness to ACTH (P < 0.001). In conclusion, our study demonstrates that, in isolated GH deficiency, replacement doses of hrGH do not modify the adrenal steroid basal levels or its responsiveness to ACTH, whereas both replacement and high doses of hrGH induce an IGF-I responsiveness to ACTH.

The effect of human growth hormone (hGH) on adrenal androgen secretion was assessed in 7 patients (5 males, 2 females) with GH deficiency but normal ACTH-cortisol function. Patients ranged in age from 9 5/12 to 14 8/12 years (median 12 years). Plasma concentrations of dehydroepiandrosterone-sulfate (DHEA-S) and urinary excretion of 17-ketosteroids (17-KS) and free cortisol were determined before, during short-term (2 U/day X 3) and after long-term (6 months) treatment with hGH. No significant change was noted in the plasma concentration or urinary excretion of steroids during the short-term administration of hGH. Despite a significant increase in growth velocity during 6 months of hGH therapy (8.2 vs. 4.5 cm/year, p less than 0.01), the plasma concentrations of DHEA-S and the urinary 17-KS and free cortisol levels were unchanged. These results fail to substantiate a role for hGH in the physiologic control of adrenal androgen secretion. Thus, the low plasma levels of adrenal androgens sometimes seen in GH-deficient patients are not due to the absence of GH per se.

Two brothers showed ichthyosis, bilateral cryptorchidism, hypogenitalism and mental retardation. In addition, the younger brother had short stature associated with disorders of secretions of insulin, ACTH and GH. This is the third reported case of the syndrome of ichthyosis and hypogonadism.

Short stature is a common complication of inflammatory bowel disease. Recently McCaffery, Nasr, Lawrence, and Kirsner (1970) concluded, from blood growth hormone (GH) levels obtained during insulin-hypoglycaemic provocation, that GH deficiency contributed to the retardation in growth observed in subjects with inflammatory bowel disease. Although it was not possible to eliminate the possibility of partial hypopituitarism, this study does not confirm the existence of GH deficiency in six subjects with short stature complicating inflammatory bowel disease. The nyctohemeral (night and day) serum GH is described, and the insulin and glucose levels in these subjects and normal sleep-related GH rises in all are demonstrated. This finding is not compatible with growth hormone deficiency. In one subject the response to arginine provocation was blunted. Three subjects manifested hyperinsulinism and evidence for ;insulin resistance'. These findings are unexplained but suggest that insulin resistance may contribute to a blunted GH response to insulin-induced hypoglycaemia. Blunted GH response to both arginine and insulin-induced hypoglycaemia may also result from continuous secretion and reduced pituitary storage of growth hormone. This possibility is suggested by the pattern of raised blood GH levels in one of the subjects.
