Hirsutism in women is defined as an excess of body hair in the androgen-sensitive skin regions. The different genetic backgrounds of various populations may affect the causes of hirsutism. In fact, the most important reason for investigation is to identify those women with androgen-secreting tumors, since they require different therapy. Hirsutism may have various causes, such as polycystic ovary syndrome, enzyme defects in adrenal steroid biosynthesis, Cushing's syndrome, acromegaly, ovarian or adrenal tumors, or it may be idiopathic. In most patients, hirsutism is associated with hyperandrogenemia and the most common cause of androgen excess is polycystic ovary syndrome. Androgen-secreting tumors should be suspected when the onset and progression of hirsutism is rapid and/or when it is associated with virilization. Patients should be informed about the type and duration of therapy. The selection of drug/drugs depends on the severity of the hirsutism, associated conditions such as menstrual irregularities, systemic disorders such as diabetes mellitus, hypertension and any contraindication to possible therapeutic agents. Diane® 35 is the most common drug used for the suppression of ovarian androgen production. Peripheral blockade of androgen actions, by using spironolactone, finasteride or flutamide on the skin, is also effective in the treatment of hirsutism.

<b><i>Introduction:</i></b> IL-1β, a cytokine from the innate immune response, is well known for its proinflammatory effects and stimulating activity on the hypothalamus-pituitary-adrenal axis, leading to the pituitary synthesis of adrenocorticotropic hormone followed by cortisol (and dehydroepiandrosterone – DHEA) release by the adrenal gland. While IL-1β modulates the adrenal steroidogenesis at the central level, it is unclear whether it also exerts an effect on the adrenal gland. <b><i>Method:</i></b> We studied the effect of IL-1β on adrenal steroid production and steroidogenic enzyme RNA expression in the human cell line NCI-H295R. We also explored eventual changes in the microRNA (miRNA) profile from IL-1β-treated NCI-H295R cells. <b><i>Results:</i></b> Transcripts encoding IL-1β receptors 1 and 2 were noticeable in the cell line, with cortisol and DHEA production showing a subtle increase after cytokine treatment. Transcripts from key enzymes in the steroidogenic pathway were analyzed, with no noticeable changes on them. The miRNA profile was modified by IL-1β treatment to an extent which bears some relationship with the regulatory mechanisms underlying adrenal steroid production. Since orphan nuclear receptors NR4As have emerged as potential key factors for coordinating inflammatory and metabolic responses, cell expression studies were also carried out to show an NR4As transcript augmentation following IL-1β treatment. <b><i>Discussion/Conclusions:</i></b> The subtle increase in adrenal steroid production in response to IL-1β stimulation without any modification in the transcription of the steroidogenic enzymes analyzed suggests an additional inflammatory/anti-inflammatory loop, wherein NR4As receptors may participate. Besides its physiological role, this process might be implied in pathological states accompanied by an unbalanced immune-endocrine relationship.
