Objective: To compare the effectiveness of finasteride and flutamide in the treatment of hirsutism in patients with polycystic ovary syndrome (PCOS) and with idiopathic hirsutism. Design: Randomized study. Patients: One hundred and ten hirsute patients were selected: 64 women with PCOS and 46 with idiopathic hirsutism. Methods: Patients were assigned randomly to receive 5 mg finasteride once daily or 250 mg of flutamide twice daily, for 12 consecutive months. Hirsutism was evaluated at 12 months of therapy, with the Ferriman-Gallwey score and with measurement of the terminal hair diameters (mm) taken from four different body areas. Blood samples were taken for assessment of endocrine and hematochemical parameters. Side effects were monitored during the treatment. Results: Both finasteride and flutamide induced a significant decrease in the hirsutism scores and hair diameters at the end of 12 months. Finasteride reduced the Ferriman-Gallwey score by 31.4% in the PCOS cases and by 34.2% in the idiopathic hirsutism cases, and hair diameter by 27.0-34.1% in PCOS and by 29.6-37.9% in idiopathic hirsutism. Flutamide reduced the Ferriman-Gallwey score by 56.7% in PCOS and by 50.9% in idiopathic hirsutism, and hair diameter by 50.3-60.0% in PCOS and by 47.7-56.5% in idiopathic hirsutism. Flutamide did not induce hormone variations, while finasteride increased testosterone levels by 40% in PCOS and by 60% in idiopathic hirsutism and decreased 3a-androstanediol glucuronide (3a-diolG) by 66.7% in PCOS and by 69.5% in idiopathic hirsutism. No important side effects or changes in the hematochemical parameters were observed with finasteride, while two patients (3.6%) in the flutamide group expressed abnormal transaminase levels after 6 months of treatment. Dry skin also appeared significantly more with flutamide (67.3%) than with finasteride (23.6%). Conclusions: Both drugs are effective in the treatment of hirsutism but flutamide is more effective than finasteride.

This study shows the effect of a long-term treatment (60 cycles) with the ethinyl oestradiol/cyproterone acetate pill, and the follow-up after 6 months from cessation, in polycystic ovarian syndrome. The 140 studied women had polycystic ovaries and moderate or severe acne, 108 also presented hirsutism. The endocrine profile significantly modified after six cycles (P < 0.001), with a further significant decrease of gonadotrophins, oestrogens and androgens after 12 cycles, and a greater increase of sex hormone-binding globulins and insulin-like growth factor-binding globulins. Between the 12th and 60th cycle there was only a significant reduction of dehydroepiandrosterone sulphate (P < 0.05). Acne disappeared in all patients within 12-24 cycles, but hirsutism was still present in 30.6% after 60 cycles. Mild-moderate hirsutism disappeared in 36-60 cycles, whereas severe hirsutism substantially decreased, but persisted. Ovarian volume, microcyst numbers and stroma percentage significantly decreased (P < 0.01). After 6 months from the end of the therapy, endocrine parameters were identical to the starting ones, acne and hirsutism reappeared, whereas ovarian morphology was between the initial and final condition. Ovaries were polycystic in 42 (30%) patients and multifolliculars in 98 (70%). Our results show the effectiveness of this combination on androgenic symptoms, especially on acne, and suggest that acne and hirsutism are induced by different peripheral mechanisms.

Results show a clinical spectrum that includes AN and FHA and suggest the necessity to treat FHA with a multidisciplinary approach for both organic and psychological aspects.
