Abstract
OBJECTIVE
The purpose of our study was to further understand interrelationships between insulin, androgens, obesity, and apolipoprotein metabolism.
STUDY DESIGN
In this University cross-sectional observational study for hypothesis generation, 53 women with hirsutism-hyperandrogenism were ternately divided according to body mass index into the following groups: 22 to 28 (n = 17), 29 to 36 (n = 19), 37 to 61 (n = 17), and 16 controls. Mean hormone and clinical parameters were compared by using the Student t test, analysis of variance, and Pearson correlation.
RESULTS
Dehydroepiandrosterone sulfate correlated negatively with fasting insulin (r = 0.4, p < 0.05) and reached significance in those most obese. Unbound testosterone concentrations were 24.7, 38.9, and 31.9 ng/dl, respectively. Dehydroepiandrosterone sulfate concentrations were 2.8, 2.3, and 2.3 micrograms/dl, respectively; their ratios were 13.4, 18.6, and 20.4, respectively, even though mean fasting insulin concentrations (reflecting insulin resistance) were 13.0, 20.4, and 42.6 microU/ml, respectively. Although more atherogenic apolipoprotein profiles and higher fasting insulin concentrations were found with greater body weight, lipid-insulin interrelationships may reflect dehydroepiandrosterone sulfate interaction.
CONCLUSIONS
We hypothesize that dehydroepiandrosterone sulfate dampens the effect of insulin resistance, which in turn is reflected in apolipoprotein profiles in women with hirsutism/hyperandrogenism.
