Serum concentrations of the adrenal androgen, dehydroepiandrosterone sulfate, were measured by radioimmunoassay in normal infants and children, in sick premature and full-term newborn infants, and in patients undergoing evaluation of the hypothalamic-pituitary-gonadal and -adrenal systems. Premature infants had significantly greater (p less than 0.001) levels of DHAS (263 +/- 40)[SE]migrong/dl) than did full-term infants (58.9 +/- 5.2) during the first ten days of life; further increments occurred in stressed "sick" infants. A gradual age- and maturity-related rise in serum concentrations of DHAS was observed during childhood with the earliest increase occurring prior to the onset of pubertal production of gonadal steroids. Serum levels of DHAS rose following administration of ACTH and were increased in patients with congenital adrenal hyperplasia, in whom rapid decrements followed treatment with dexamethasone. hCG or LH-RH treatment did not alter DHAS concentrations. These data suggest that direct secretion of DHAS by the adrenal gland and/or peripheral sulfation of DHA, rather than gonadal secretion, accounts for the majority of DHAS production. The involvement of adrenal androgens in the pubertal maturation of the reproductive endocrine system thus may be evaluated by quantitation of serum DHAS.
采用放射免疫分析法测定了正常婴幼儿、患病早产儿和足月儿以及接受下丘脑 - 垂体 - 性腺和肾上腺系统评估的患者血清中肾上腺雄激素硫酸脱氢表雄酮(DHAS)的浓度。早产儿在出生后的头十天内,其DHAS水平(263±40[标准误]μg/dl)显著高于足月儿(58.9±5.2)(p<0.001);在处于应激状态的“患病”婴儿中,DHAS水平进一步升高。在儿童期观察到血清DHAS浓度随年龄和成熟度逐渐升高,最早的升高发生在青春期性腺类固醇产生之前。给予促肾上腺皮质激素(ACTH)后,血清DHAS水平升高,先天性肾上腺皮质增生症患者的血清DHAS水平也升高,这些患者在用地塞米松治疗后迅速下降。人绒毛膜促性腺激素(hCG)或促黄体生成素释放激素(LH - RH)治疗并未改变DHAS浓度。这些数据表明,肾上腺直接分泌DHAS和/或DHA的外周硫酸化,而非性腺分泌,是DHAS产生的主要原因。因此,可通过定量血清DHAS来评估肾上腺雄激素在生殖内分泌系统青春期成熟过程中的作用。
