Plasma steroid dynamics in Cushing's syndrome. 1978

M Luisi, and F Franchi, and D Drafta, and E Stroe

The dynamics of five plasma steroids were studied by CPB and RIA in twenty patients with Cushing's syndrome of differing etiologies: pituitary induced adrenal hyperplasia (10), recurrence after adrenal surgery or pituitary irradiation (4), adrenal carcinoma (4) and adrenal adenoma (2). Basal mean values of plasma steroids, showed increase of cortisol in hyperplasia and cancer groups, increase of 17-hydroxyprogesterone (17-OH-P) in recurrence and cancer groups and decrease of testosterone in male patients. In hyperplasia, the changes in 11-desoxycortisol and 17-OH-P (respectively by CPB assay and RIA after LH-20-Sephadex separation) were the reverse of those for cortisol 2 h and 24 h after metyrapone administration. Adrenalectomy determined in all but one patients, significant decrease of cortisol and in male patients, parallel gradual increase of testosterone.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011374 Progesterone The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

D002675 Child, Preschool A child between the ages of 2 and 5. Children, Preschool,Preschool Child,Preschool Children
D003480 Cushing Syndrome A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.

D004964 Estriol A hydroxylated metabolite of ESTRADIOL or ESTRONE that has a hydroxyl group at C3, 16-alpha, and 17-beta position. Estriol is a major urinary estrogen. During PREGNANCY, a large amount of estriol is produced by the PLACENTA. Isomers with inversion of the hydroxyl group or groups are called epiestriol.
