title: Growth in disorders of adrenal hyperfunction.
abstract: This article reviews how growth is affected in disorders of adrenal hyperfunction. Growth is disturbed by adrenal hypersecretion of androgens or cortisol. Adrenal androgens, when in excess, lead to advanced linear growth and skeletal maturation, and prolonged hypercortisolemia leads to the suppression of growth hormone (GH) secretion and inhibition of somatomedin C and other growth factor effects on their target tissues. In virilizing adrenal tumors height is increased at diagnosis, but after surgical cure the final height is usually in the normal range. In congenital adrenal hyperplasia height is usually compromised by advanced skeletal maturation or by suppressed growth, particularly in the first years of life, due to excess glucocorticoid treatment. The final height is reduced in both clinical forms (salt wasting and simple virilizing) and sexes in patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Growth impairment is also the hallmark of Cushing syndrome of whatever etiology when it occurs in children and growing adolescents, and the final height of these patients, even after surgical cure, remains compromised. This is apparently due to direct or indirect growth impairment by the hypercortisolism during the disease, followed by inadequate catch-up growth. Although it seems that GH treatment might be beneficial for improving final height both in patients with congenital adrenal hyperplasia who have poor height predictions and in patients with Cushing disease and GH deficiency, a larger number of studies is needed to confirm this suggestion.
