    Abstract:
    Some children with congenital adrenal hyperplasia (CAH) develop true precocious puberty with early maturation of the hypothalamic-pituitary-gonadal axis. We have seen six such children who had the diagnosis of CAH with late initiation of corticosteroid treatment and/or poor compliance who developed central precocious puberty (CPP). These patients were treated with standard-dose hydrocortisone and fludrocortisone. Administration of depot leuprorelin (3.75 mg subcutaneously every 28 days) for 2 years or longer was effective in arresting the manifestations of puberty, decelerating the pretreatment growth velocity ([GV] 10.8 +/- 1.5 v3.65 +/- 0.95 cm/yr), increasing the predicted adult height ([PAHT] 147.5 +/- 7.8 v 153.4 +/- 8.3 cm), and decreasing the bone age to statural age ratio (1.26 +/- 0.13 v 1.16 +/- 0.09). Analysis of auxanological data during the first 2 years of life showed that linear growth was significantly accelerated and bone age was advanced in patients who developed CPP compared with 11 age-matched patients. It appears that proper glucocorticoid replacement to achieve adequate control of hyperandrogenemia during early life might prevent development of CPP in these patients. Gonadotropin-releasing hormone agonist (GnRHa) therapy can improve the final adult height, bringing it closer to that expected from the genetic potential.
