[Correlations between clinical signs and hormonal parameters in young women with hirsutism].
Hyperandrogenism is the pathological condition, which clinical signs are "androgendependent dermopathies" (seborrhea, acne, hirsutism, alopecia) and not in every cases evidence with hyperandrogenemia. Free testosterone is the most frequent marker of hyperandrogenism, but its determination routinely not feasible in all laboratories. Therefore, some models for calculating free and bioavailable testosterone have been developed. In women the testosterone sources are not only ovaries and adrenal glands, but also abdominal and peripheral fat. There are many investigations to definite correlations between body mass index, androgens and sex hormone binding globulin.  The aim of this study was to define the correlations between clinical, biochemical markers of hyperandrogenism and body mass index, with regard of abdominal obesity in young women with hirsutism.  83 female adolescents (14-20 year) with hirsutism and 20 female adolescents in control group were included. C-peptide, estradiol, total testosterone, sex hormone binding globulin (SHBG) were measured. Free androgen index (FAI), free (cFT) and bioavailable (Bio-T) testosterone were calculated. The levels of C-peptide and glucose were used to compute Homa-IR (homeostasis model assessment for insulin resistance).  There were detected significant high levels by all hormonal parameters of hyperandrogenism in women with hirsutism, than in control group. In patients with abdominal obesity were also found significant high levels by all calculated parameters of hyperandrogenism and significant low level of steroid-bind globulin, than in patients with central obesity. In two groups by hirsutism degree were not detected any differences between androgen markers.   The findigs of this research suggest, that android obesity in female adolescents with hirsutism can cause harder hyperandrogenism and elevate free androgen index, free and bioavailable testosterone levels. The prophylactic reduction of body mass index may prevent complications.
