[Two case reports of long-term treatment of endometriosis with cyproterone acetate].

Endometriosis is a benign, chronic disease with high incidence during the female fertile period. Conservative treatment is dominated by the use of GnRH-analog substances, Gestagens and Danazol. As a case report we present the signs and symptoms, as well as the long term therapeutical strategy in two cases of severe endometriosis. Combined with signs of hyperandrogenism, the long term use of cyproteroneacetate is beneficial.

Efficacy of the combination ethinyl oestradiol and cyproterone acetate on endocrine, clinical and ultrasonographic profile in polycystic ovarian syndrome.

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.

Clinical, endocrine and metabolic effects of metformin added to ethinyl estradiol-cyproterone acetate in non-obese women with polycystic ovarian syndrome: a randomized controlled study.

BACKGROUND: Oral contraceptive pills (OC) are usually the first choice of treatment for polycystic ovarian syndrome (PCOS), when fertility is not desired. However, they do not improve, or may even further induce impairment of insulin sensitivity, which is already impaired in women with PCOS. In this prospective, randomized study, we analysed the additional benefits of adding metformin to the OC treatment in non-obese women with PCOS. METHODS: After a baseline work-up including body mass index (BMI), waist:hip ratio (WHR), Ferriman-Gallwey score, ovarian volume, serum gonadotrophin, androgen and sex hormone-binding globulin (SHBG) levels, and fasting lipid, glucose and insulin levels, 40 non-obese women with PCOS were assigned either to the OC or to the OC + metformin treatment by computer-assisted randomization. At the end of the 4 month follow-up period, subjects were re-evaluated. RESULTS: The two groups were similar at baseline. After treatment, women in the OC + metformin group had significant decreases in BMI and WHR, and a significant increase in insulin sensitivity, in contrast to those in the OC group, who had insignificant changes in these parameters. Adding metformin also caused significant improvements in serum androstenedione and SHBG levels compared with the OC treatment alone. CONCLUSIONS: Adding metformin to the OC treatment may improve the insulin sensitivity, and may further suppress the hyperandrogenaemia in non-obese women with PCOS.
