The effect of the administration of a biphasic oral contraceptive containing ethinyloestradiol and desogestrel on the distribution and composition of serum lipoproteins was studied in a group of 17 healthy female volunteers. The women were treated for a period of 6 months and compared with a control group of ten untreated volunteers. The serum lipoproteins were fractionated by density gradient ultracentrifugation into very low density lipoproteins (VLDL), low density lipoproteins (LDL), and into the high density lipoprotein (HDL) subfractions 2 and 3 (HDL2, HDL3). Lipids and apolipoproteins were assayed in the various fractions. No modification of either the lipid or apolipoprotein concentrations was observed in the control group. In the treated group, sex hormone-binding globulin (SHBG) and cortisol-binding globulin (CBG), and the serum content of cholesterol, triglycerides, HDL-cholesterol, apolipoprotein A-I (apo A-I) and apolipoprotein A-II (apo A-II) increased significantly after 3 and 6 months. The cholesterol and apolipoprotein B (apo B) content of VLDL increased significantly after 3 and 6 months, but remained unchanged in LDL. High density lipoprotein subfraction 2 (HDL2)-cholesterol was significantly increased after 3 and 6 months but apo A-I only after 6 months. Since apo A-II did not change, the apo A-I/A-II ratio increased significantly after 6 months of treatment. In the HDL3 fraction, the apo A-I increase was significant after 3 and 6 months, while the increase of apo A-II was significant after 6 months. The apo A-I/A-II ratio remained constant.(ABSTRACT TRUNCATED AT 250 WORDS)
