Effects of a low-estrogen, desogestrel-containing oral contraceptive on lipid and carbohydrate metabolism.
Fasting serum lipids, lipoproteins and apolipoproteins, and fasting plasma glucose, insulin and C-peptide were measured in 107 non-users and 83 users of an oral contraceptive containing the progestin desogestrel, combined with 20 micrograms ethinyl estradiol. Plasma glucose, insulin and C-peptide concentrations during an oral glucose tolerance test (OGTT) were measured in a subgroup of 69 non-users and 39 users. Compared with non-users, users had higher concentrations of total, high density lipoprotein (HDL), HDL subfraction 3 and very low density lipoprotein (VLDL) cholesterol, total triglycerides, VLDL triglycerides, apolipoproteins AI and AII and fasting plasma insulin. There were no differences in HDL subfraction 2, low density lipoprotein cholesterol and apolipoprotein B. OGTT glucose was 60% higher in the users and OGTT insulin response 19% higher. The OGTT C-peptide response did not differ. The effects of 20 micrograms ethinyl estradiol combined with 150 micrograms desogestrel on lipid, lipoprotein, glucose and insulin metabolism are similar to those described previously with a 30 micrograms ethinyl estradiol combination containing the same dose of desogestrel. The relatively favourable metabolic profile associated with the higher estrogen dose desogestrel combination is maintained at the lower dose.
