title: Failure of dehydroepiandrosterone enanthate to promote growth.
abstract: Adrenal androgens may promote pubertal growth. To assess this possibility, we administered dehydroepiandrosterone (DHEA) enanthate in monthly im injections in a dose of 70 mg/m2 for 1 yr to five boys with constitutional short stature (aged 11-13 4/12 yr) and one boy (aged 13 4/12 yr) with panhypopituitarism (coincidentally receiving T4 and human GH). All had bone age delay of at least 3 yr and subnormal levels of DHEA and DHEA sulfate (DHEA-S) for their chronological age. Pretreatment growth velocity ranged from 3-5 cm/yr. After DHEA enanthate injection, plasma DHEA levels were increased 10-fold after 8 days, 2.6-fold after 15 days, and 1.8-fold after 22 days. At the same times, plasma DHEA-S concentrations were 14-, 6-, and 4-fold increased, respectively. There was no rise in plasma testosterone and delta 4-androstenedione, which remained at prepubertal levels. During the year of therapy and for 1 yr after therapy, there was no significant change in growth velocity, and the rate of skeletal maturation assessed by x-ray was not affected. Three of the five boys with constitutional short stature entered puberty within 1 yr after discontinuation of therapy. These results demonstrate that this long-acting form of DHEA administered for 1 yr did not raise plasma testosterone above prepubertal levels and did not accelerate either growth or skeletal maturation. These findings do not support the possibility that DHEA plays a role in normal growth.
