Androgen and lipid profiles in adolescents with polycystic ovary syndrome who were treated with two forms of combined oral contraceptives.
OBJECTIVE: To compare the effects of cyproterone acetate and desogestrel, as part of combined oral contraceptives, on lipid metabolism and hirsutism of adolescents with polycystic ovary syndrome (PCOS). DESIGN: Prospective randomized clinical trial. SETTING: Outpatient gynecology clinic (referral center) of a university. PATIENT(S): Twenty-eight adolescent girls with clinical and biological hyperandrogenism and six or less menses during the past 12 months. INTERVENTION(S): Group A (n = 14) received 0.15 mg of desogestrel plus 0.030 mg of ethinyl estradiol daily. Group B (n = 14) received 2 mg of cyproterone acetate plus 0.035 mg of ethinyl estradiol daily. Treatment was given for 21 days followed by a 7-day rest for a period of 12 months. MAIN OUTCOME MEASURE(S): Hirsutism and lipid profile were evaluated before initiation and at 3, 6, 9, and 12 months of treatment. Androgen profile was evaluated before and at 12 months of treatment. RESULT(S): A significant decline of the Ferriman-Gallway hirsutism score was observed from the sixth month of therapy in both groups. During therapy, the levels of testosterone, free testosterone, Delta(4)-androstenedione, and 17OH-progesterone decreased significantly, whereas sex hormone-binding globulin (SHBG) increased significantly in both groups. The level of total cholesterol and low density lipoprotein (LDL) cholesterol increased significantly, whereas high density lipoprotein (HDL) cholesterol and apolipoprotein A-I increased significantly from the third month of therapy in both groups. Total cholesterol/HDL cholesterol and LDL cholesterol/HDL cholesterol ratios remained unchanged. The levels of triglycerides increased significantly in the cyproterone acetate-treated group after the third month. CONCLUSION(S): Treatment of adolescent girls with PCOS with the two studied formulations is comparably effective in decreasing hirsutism and androgen levels. Both combined oral contraceptives are associated with an increase of total cholesterol, LDL cholesterol, and HDL cholesterol levels and no change of the total cholesterol/HDL cholesterol and LDL cholesterol/HDL cholesterol ratios. Treatment with the cyproterone acetate combined oral contraceptive is associated with a tendency toward increasing the levels of triglycerides.[1]References
