Hyperandrogenic women appear to demonstrate an exaggerated
17-hydroxyprogesterone (17-HP) response to adrenal stimulation which is not due to the marked
21-hydroxylase deficiency of late-onset adrenal
hyperplasia (LOAH). Furthermore, in
hyperandrogenism the ovary also appears to secrete excessive amounts of 17-HP. It is not clear to what extent the elevated 17-HP levels after
ACTH stimulation are due to extraadrenal production of the
steroid. This investigation was undertaken to assess the adrenal contribution to the elevated 17-HP levels after
ACTH stimulation observed in non-LOAH
hyperandrogenism. One hundred and sixty consecutive unselected women with
hirsutism and/or hyperandrogenic
oligomenorrhea formed the clinical population. Excluded were 4 women with LOAH and all patients with
hyperprolactinemia. For the purpose of investigating the relationship between adrenal response and clinical symptoms, hyperandrogenic patients were divided into 3 subgroups: hirsute only (n = 23), hirsute oligomenorrheic (n = 84), and oligomenorrheic only (n = 24). Subclassification for an additional 29 patients (18%) with hyperandrogenemia was not possible, since their symptomatology was not clearly stated in the record. However, these individuals were included in the patient group as a whole. Controls consisted of 21 healthy, regularly menstruating, nonhirsute female volunteers. Both patients and controls underwent acute adrenal stimulation with 1 mg ACTH-(1-24), and serum was obtained before and 30 min after
ACTH administration. Hyperandrogenic patients had higher mean basal total
testosterone (T),
androstenedione (A),
dehydroepiandrosterone sulfate (DHS), 17-HP, and LH/FSH levels, but not
cortisol (F), compared to normal subjects (P less than 0.02). Oligomenorrheic only women had higher mean A and
progesterone (P) levels than other hyperandrogenic patients (P less than 0.02). No correlation was noted between body mass index (BMI) and the levels of DHS, P, or A, while a weak positive association was noted between the BMI and the mean T (r = 0.31; P less than 0.002) and a weak negative correlation between the mean F and BMI (r = -0.21; P less than 0.05). The mean 17-HP level 30 min after
ACTH administration (17-HP30) was significantly higher in hyperandrogenic women than in normal subjects whether analyzed in separate subgroups or together and was due to the higher basal 17-HP levels. Basal 17-HP correlated with the circulating levels of T, A, and P,
steroids largely of ovarian origin. Alternatively, the net increment in 17-HP from 0-30 min after
ACTH (delta 17-HP30) was not significantly higher in hyperandrogenic women than normal subjects and did not correlate with the basal levels of T, A, and P. Neither the basal level of 17-HP nor its response to
ACTH correlated with circulating DHS levels.(ABSTRACT TRUNCATED AT 400 WORDS)
