Objective: To evaluate the therapeutic effects of a GnRH agonist (GnRH-a), leuprolide acetate (LA) plus a pill containing ethinyl E2 plus cyproterone acetate (CPA) in a group of women with severe hirsutism who were unresponsive to oral contraceptive (OC) therapy.
Design: Twenty-four patients suffering from severe hirsutism secondary to polycystic ovary disease (PCOD) were treated for 12 months with 3.75 mg IM LA every 28 days in association with 0.035 mg/d ethinyl E2 plus 2 mg/d CPA (Diane; Schering, Berlin, Germany) for 21 d/mo.
Setting: Patients were recruited in the Institute of Obstetrics and Gynecology, St. Bambino Hospital, University of Catania, Catania, Italy. Hormonal assays were performed in the Hormone Laboratories of St. Bambino Hospital, University of Catania, Catania, Italy.
Main outcome measures: Every 3 months the hirsutism score was evaluated. Mean serum concentrations of LH, FSH, E2, total and free T, androstenedione (A), sex hormone-binding globulin (SHBG), and DHEAS were determined. Every 6 months a vaginal ultrasound examination was performed.
Results: In all patients after 6 and 12 months of treatment with LA plus OC, the hirsutism score improved significantly. Serum levels of LH, FSH, E2, total and free T, A, and DHEAS decreased significantly, whereas SHBG showed a marked increase. A significant reduction in the ovarian size was observed.
Conclusion: Gonadotropin-releasing hormone agonist, associated with a pill containing CPA, reduced the hirsutism in severely affected women with PCOD who are unresponsive to OC treatment alone.
