reduced hydrocortisone dose, and fludrocortisone) can normalize growth in children with congenital adrenal hyperplasia.\n\nThe study will take 60 children, boys and girls and divide them into 2 groups based on the medications given. Group one will receive the new four- drug combination. Group two will receive the standard treatment for congenital adrenal hyperplasia (hydrocortisone and fludrocortisone).\n\nThe boys in group one will take the medication until the age of 14 at which time they will stop taking the four drug combination and begin receiving the standard treatment for congenital adrenal hyperplasia. Girls in group one will take the four drug combination until the age of 13, at which time they will stop and begin receiving the standard treatment for congenital adrenal hyperplasia plus flutamide. Flutamide will be given to the girls until six months after their first menstrual period.\n\nAll of the children will be followed until they reach their final adult height. The effectiveness of the treatment will be determined by measuring the patient's adult height, body mass index, and bone density. <TAB>...", "DetailedDescription"=>"To test the hypothesis that the regimen of flutamide (an antiandrogen), testolactone or letrozole (an inhibitor of androgen-to-estrogen conversion), and reduced hydrocortisone dose can normalize the growth and adult stature of children with congenital adrenal hyperplasia, and can avoid the complications of supraphysiologic glucocorticoid dosage, 60 children with this disorder will be randomized to receive either the above regimen or conventional treatment until they have reached age 13 years in a girl or age 14 in a boy. After these ages boys will receive the conventional treatment and girls will receive conventional treatment plus flutamide. In girls, flutamide will be continued until 6 months after menarche. All children will be followed until they have attained final adult height.
