  • Title: Usefulness of plasma pregnenolone sulfate in testing pituitary-adrenal function in children.
    Author: de Peretti E, Forest MG, Loras B, Morel Y, David M, François R, Bertrand J.
    Journal: Acta Endocrinol Suppl (Copenh); 1986; 279():259-63. PubMed ID: 3022522.
    Abstract:
    In normal subjects, plasma pregnenolone sulfate (PS) levels high at birth, decreased during the first year of life in relation to the pattern of involution of the fetal adrenal zone. Thereafter, PS levels, in contrast with those of DHAS, did not show the abrupt rise characteristic of the adrenarche, but increased very progressively till adulthood. The response of PS to various provocative tests of adrenal and pituitary function (ACTH and Metyrapone stimulation, dexamethasone suppression), has been established in normal subjects. The measurement of plasma PS levels in basal conditions as well as in response to dynamic tests was very useful in the diagnosis of various adrenal and pituitary diseases in children.
