Adrenal androgens in children with short stature. Academic Article uri icon

Overview

abstract

  • Recent data suggest that adolescent individuals with growth hormone (GH) deficiency have subnormal levels of adrenal androgens (AA). In order to determine the developmental pattern of AA in GH deficiency and to assess whether AA levels can help identify children with GH deficiency, we measured plasma concentrations of dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), delta 4-androstenedione (delta 4A), and cortisol in the basal state and during prolonged adrenocorticotropin (ACTH) infusion (8 h) in a group of 34 individuals, 26 males and 8 females, with short stature. Their chronological ages (CA) ranged from 1.75 to 17.5 years (median 10.35 years). The subjects were grouped into two categories according to the results of pituitary testing: group 1 = short, non-GH-deficient (n = 16), and group 2 = GH-deficient, ACTH-sufficient (n = 18). Patients in groups 1 and 2 had similar bone ages (BA: 7.2 +/- 0.7 vs. 7.5 +/- 1.0 years) and Z scores for height (-3.0 +/- 0.2 vs. -3.2 +/- 0.3 units) and height velocity (-2.5 +/- 0.4 vs. -2.6 +/- 0.2 units). For both groups there were significant increases from basal to peak levels for DHEA, DHEA-S, delta 4A and cortisol following prolonged ACTH infusion. Although both basal and peak levels of DHEA-S overlapped in groups 1 and 2 for all CA and BA, levels in group 2 tended to be lower, especially for BA greater than 10 years.(ABSTRACT TRUNCATED AT 250 WORDS)
