AIM: To assess the effect of combined oral contraceptives (COCs) and intrauterine devices (IUDs) on carbohydrate and lipid metabolism and hemostasis in perimenopausal diabetic women. METHODS: The open randomized study included a total of 113 diabetic women using COCs with differentestrogen/progestogen profiles - ethinylestradiol (EE) 20 microg/desogestrel 150 microg, EE 30 microg/desogestrel 150 microg and EE 30 microg/gestodene 75 microg - and levonorgestrel-releasing or copper IUDs. Average daily insulin requirements, levels of glycosylated hemoglobin, total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol, the state of coagulation hemostatis and fibrinolytic activity were determined at baseline and after 3, 6, 9 and 12 months of contraception. The control group was composed of 40 age-matched diabetic women who did not use any methods of contraception. RESULTS: Neither COCs nor IUDs influenced glycosylated hemoglobin and had little or no influence on the elevation in the requirements for insulin preparations. The majority of the preparations did not exert any unfavorable effect on the blood lipid profile. Taking COCs was accompanied by increased intravascular activation of blood platelets and to a lesser degree by alterations in parameters of hemostatic homeostasis. The use of IUDs had a neutral effect on blood coagulation and fibrinolysis systems. CONCLUSION: Comparing lipid levels and hemostatic variables as a function of glycosylated hemoglobin level, we conclude that diabetes control has greater influence on these parameters than the type and dose of steroids involved in the contraceptive devices.
