D. Cibula et al., The best correlation of the new index of hyperandrogenism with the grade of increased body hair, EUR J ENDOC, 143(3), 2000, pp. 405-408
Objective: Hyperandrogenemia is the most frequent endocrine disorder in fer
tile women causing a variety of negative metabolic disturbances. Establishi
ng the diagnosis of androgen overproduction has important implications for
the follow-up and treatment of patients. The aim of our study was to identi
fy the optimal laboratory marker of androgen production by correlating the
markers to the presence or grade of increased body hair as a clinical sign
of hyperandrogenism.
Design: Prospective observational study.
Methods: A total of 62 women with acne were included into the study. The se
rum concentrations of testosterone, androstenedione, dehydroepiandrosterone
(DHEA), DHEA sulfate (DHEAS) and sex hormone-binding globulin (SHBG) were
evaluated. The index of free testosterone (IFT) and a new index of hyperand
rogenism (IHA) were calculated. The monitored laboratory markers were corre
lated to the presence or grade of increased body hair using several statist
ical methods.
Results: The statistical significance of differences between the average le
vels of laboratory markers between hirsute and non-hirsute women decreased
in the following order: IHA, androstenedione and DHEA. Of all the above lab
oratory markers, only increased IHA was present significantly more often in
hirsute women. The significance of correlation between the grade of increa
sed body hair and the tested variables decreased in the following order: IH
A, IFT, DHEA, androstenedione, DHEAS and testosterone.
Conclusions: The clinical marker of hyperandrogenism correlates most closel
y to IHA, reflecting the levels of all commonly determined androgens or and
rogen precursors and SHBG, Its simple calculation makes IHA a suitable tool
for determining total production of androgens in clinical practice, especi
ally in cases with borderline elevations of values.
