Spironolactone therapy in hypertrichosis

Spironolactone might be a desirable immunologic and hormonal intervention in autism spectrum disorders

Multiple studies now demonstrate that autism is medically characterized, in part, by immune system dysregulation, including evidence of neuroglial activation and gastrointestinal inflammation. This neuroglial process has further been characterized as neuroinflammation. In addition, a subset of autistic children exhibit higher than average levels of androgens. Spironolactone is an aldosterone antagonist and potassium-sparing diuretic with a desirable safety profile. It possesses potent anti-inflammatory and immune modifying properties that might make it an excellent medical intervention for autism spectrum disorders. Furthermore, spironolactone demonstrates substantial anti-androgen properties that might further enhance its appeal in autism, particularly in a definable subset of hyperandrogenic autistic children. One case report is briefly reviewed demonstrating objective clinical improvements in an autistic child after spironolactone administration. Additional research in controlled trials is now needed to further define the risks and benefits of spironolactone use in children with autism.

Functional hyperandrogenism detected by corticotropin and GnRH-analogue stimulation tests in women affected by apparently idiopathic hirsutism

The etiologic diagnosis of hirsutism is often difficult. Previous studies have reported normal basal androgen and SHBG concentrations in 33-50% of hirsute women, suggesting the presence of an "idiopathic" form of hirsutism as the most frequent cause of this problem. The recent use of GnRH-analogues together with the corticotropin stimulation test allows better understanding of whether the cause of hirsutism is androgen excess and, if so, whether the origin of the latter is ovarian, adrenal or both. The present study evaluated adrenal and ovarian function in 48 young hirsute women as well as in 78 normal women matched for body mass index and age, who acted as control group. To determine ovarian function, a single 100-microg dose of GnRH analogue triptorelin was injected s.c.; thereafter, gonadotropins, 17-hydroxyprogesterone (17-OHP), delta4-androstenedione (delta4), total testosterone (T) and estradiol were determined. To better understand the adrenal function, 250 microg of 1,24 ACTH were administrated as i.v. infusion for 5 h, and plasma cortisol (F), 17-OHP, A4, DHEAS, T, 11-desossicortisol were measured. The combined use of these two stimulation tests was able to detect mild to moderate abnormalities in the steroidogenesis of ovaries alone (23%), adrenals alone (16.6%), or both (35.4%) in most hirsute women (75%) with otherwise normal baseline androgen concentrations. In particular, patients showed significantly increased responses of 17-OHP, delta4, total T, 11-desossicortisol, and F to 1,24-ACTH administration. Moreover, they also had significantly higher 17-OHP and T responses to triptorelin. In conclusion, milder forms of functional ovarian and/or adrenal hyperandrogenism, similar to those found in clearly hyperandrogenic women, were observed and could be an underlying mechanism of idiopathic hirsutism.

Polycystic ovary syndrome

Polycystic ovary syndrome is a syndrome and not a disease. It reflects multiple potential etiologies and variable clinical presentations that are reviewed in this article. In addition to menstrual dysfunction and hyperandrogenism, women with polycystic ovary syndrome also may have hypothalamic-pituitary abnormalities, polycystic ovaries on pelvic ultrasonography, infertility, obesity, and insulin resistance. A familial pattern occurs in some cases, suggesting a genetic component to the disorder. The three major pathophysiologic hypotheses that have been proposed to explain the clinical findings of the disorder as well as treatment options are reviewed in this article.

Hyperandrogenism in the adolescent female

Hirsutism in adolescent girls commonly starts as an esthetic problem in young women and is later complicated by the development of infertility and polycystic ovary syndrome, which are frequent consequences of prolonged hyperandrogenism. To ascertain whether particular prepubertal clinical manifestations may predict the development of adolescent hirsutism, we followed 70 girls with precocious pubarche (PP) with or without prepubertal hypertrichosis (PH) until 3 years (mean age 14.8 +/- 0.9 years) after menarche. Similar follow-up was carried out in six girls with PP secondary to 21 hydroxylase deficiency (NC-CAH), treated with hydrocortisone. In addition, a retrospective study on the incidence of precocious pubarche was performed in 139 hirsute teenagers (mean age 17 +/- 1.8 years). Testosterone, androstenedione, dehydroepiandrosterone sulphate, 17 alpha-hydroxyprogesterone (basal and after ACTH), luteinizing hormone and follicle-stimulating hormone were evaluated by radioimmunoassay or immunoradio metric assay in the early follicular phase, in cycling subjects. Pelvic ultrasonography was also performed. In the 139 hirsute teenagers, 29 had a history of PP (21% vs. 0.6% in the general Italian population). Of these 139 patients, NC-CAH was diagnosed in 8 (6%), 5 of whom (63%) had PP. Of the 70 girls with PP, hirsutism was present in 44 (63%). PH was present in 37 of 44 patients (84%) with hirsutism, but only in 9 of 26 (35%) without hirsutism. Our results showed that 1) PP represents a risk factor for the development of postpubertal hirsutism; 2) the association with PH seems to increase the risk probability; and 3) patients with hirsutism due to NC-CAH have a higher incidence of PP compared with other hirsute patients, but glucocorticoid treatment in such patients prevents the development of hirsutism. Whether early treatment in the other PP patients may prevent the development of hirsutism remains to be established.
