OBJECTIVE: To study the effects of the slightly estrogen-dominant monophasic low-dose oral contraceptive (OC) Diane-35 (Schering AG, Berlin, Germany) (35 micrograms ethinyl estradiol [EE2] + 2 mg cyproterone acetate, a 17 alpha-hydroxyprogesterone derivative [17-OHP]) on glucose and insulin metabolism. DESIGN: Seven healthy young women were investigated by using the euglycemic hyperinsulinemic glucose clamp technique (insulin delivery rate = 100 mU/kg per hour for 120 minutes). This test was performed, after an overnight fast, during the last 7 days of a spontaneous cycle and within the last 5 days of pill intake during the sixth and twelfth cycle of a continuous treatment with Diane-35 in each subject. RESULTS: The three indexes measuring the insulin-induced glucose disposal during the clamp (glucose infusion rate, glucose metabolic clearance rate, and glucose infusion rate divided by plasma insulin plateau levels) were not significantly affected by Diane-35. In contrast, the metabolic clearance rate of the exogenous insulin infused during the clamp tended to be slightly increased with Diane-35 (significant after 6 but not after 12 cycles). CONCLUSION: These results suggest that a 1-year treatment with the OC Diane-35, which contains EE2 + a 17-OHP rather than a 19-nortestosterone derivative as the progestogen compound, does not significantly alter peripheral (presumably muscular) insulin sensitivity but slightly increases insulin (presumably hepatic) clearance.

To investigate the effects of two slightly estrogen-dominant, monophasic, low-dose oral contraceptives on carbohydrate metabolism, 40 healthy young women were randomly allocated to receive either 30 micrograms of ethinyl estradiol + 150 micrograms of desogestrel, a 19-nortestosterone-derived progestin (Marvelon; n = 21) or 35 micrograms of ethinyl estradiol + 2 mg of cyproterone acetate, a 17-acetoxyprogesterone derivative (Diane-35; n = (19) for a prospective observation period of 1 year. At baseline, 6, and 12 months, blood glucose, plasma insulin, and plasma C-peptide levels were measured during an oral glucose tolerance test. Although the changes were absent (Marvelon) or minimal (Diane-35) at 6 months, both groups had a slight increase in blood glucose levels at 12 months; overall glucose tolerance remaining, however, within the normal range. Plasma insulin levels remained unchanged in the Diane-35-group, which suggested increased insulin resistance, but were significantly decreased in the Marvelon group despite significant rises in plasma C-peptide levels. Comparison of plasma C-peptide and insulin changes suggests enhanced pancreatic insulin secretion and increased hepatic insulin metabolism with both Marvelon and Diane-35. [less ▲]
