Use of the NuvaRing® hormone-releasing system in late reproductive-age women with type 1 diabetes mellitus

Abstract

Aim. To evaluate the effect of the vaginally inserted hormone-releasing system NuvaRing® on carbohydrate and lipid metabolism and the hemostasis system, over 6 months of use, in late reproductive-age women with type 1 diabetes mellitus (DM).Methods. The open randomized study included a total of 25 women with type 1 DM using NuvaRing. Average daily insulin requirements, levels of glycosylated hemoglobin (HbA1c), 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 and 6 months of contraception. The control group was composed of 20 age-matched women with type 1 DM using no methods of contraception, as well as 20 apparently healthy women using the NuvaRing device.Results. Use of the NuvaRing contraceptive system in type 1 DM women in the late reproductive period was shown to exert no clinically significant effect on carbohydrate and lipid metabolism on the background of persistent and satisfactory compensation of carbohydrate metabolism (HbA1c ≤ 7.5%), with a neutral impact on the hemostasis system.Conclusion. The NuvaRing hormone-releasing system proved to be a reliable and safe means of contraception for late reproductive-age women with type 1 DM.
