Objective. We tested the hypothesis that postpartum combined oral contraceptive (COC) treatment would induce oxidative stress via the adenosine deaminase-xanthine oxidase pathway in the kidney. We also sought to determine whether mineralocorticoid receptor (MR) or glucocorticoid receptor (GR ) blockade would suppress the activities of ADA and xanthine oxidase caused by postpartum COC treatment in the kidney. Methods. Twenty-four Wistar dams were randomly assigned to 4 groups ( n = 6 / group ). Dams received vehicle (po), COC (1.0 μg ethinylestradiol and 5.0 μg levonorgestrel; po), COC with GR blockade (mifepristone; 80.0 mg/kg; po), and COC with MR blockade (spironolactone; 0.25 mg/kg; po) daily between 3rd and 11th week postpartum. Results. Data showed that postpartum COC caused increased plasma creatinine and urea, increased renal triglyceride/high-density lipoprotein ratio, free fatty acid accumulation, alanine aminotransferase, gamma-glutamyltransferase, uric acid, and activities of renal XO and ADA. On the other hand, postpartum COC resulted in decreased plasma albumin, renal glutathione, and Na+-K+-ATPase activity with no effect on lactate production. However, MR or GR blockade ameliorated the alterations induced by postpartum COC treatment. The present results demonstrate that MR or GR blockade ameliorates postpartum COC-induced increased activities of ADA and xanthine oxidase and restores glutathione-dependent antioxidative defense. Conclusion. These findings implicate the involvements of GR and MR in renal dysfunctions caused by COC in dams via disrupted glutathione antioxidative barrier.

Androgen-dependent dermopathy, as well as premenstrual syndrome of varying severity in young women, can cause emotional depression, difficulties in social adaptation and even depressive disorders. The aim of the study was to study the safety and efficacy of using a combined oral contraceptive (COC) Dimia® containing 20 μg ethinyl estradiol and 3 mg drospirenone in young women, as well as its therapeutic effects in androgen-dependent dermopathy. Materials and methods. The study included 57 young women aged 23.1±2.2 years with signs of androgen-dependent dermopathy. The evaluation of the change in the character of menstrual bleeding, the anthropometric parameters (body weight, waist circumference and hips), the therapeutic effect of the drug on the symptoms of androgen-dependent dermopathy, as well as the dynamics of arterial pressure, hemoglobin level, serum iron have been studied. The psycho-emotional state was assessed using the SAN questionnaire (well-being-activity-mood). Results. During 6 months of observation, there was no significant change in the body mass index, waist circumference, and hips, and the drug did not affect the blood pressure numbers. Against the background of taking the drug, there was an increase in the parameters of iron metabolism (hemoglobin content, serum iron). After 3 months of taking the contraceptive with drospirenone, the number of patients with a complaint about the abundance of menstruation decreased more than twofold (from 22.8 to 10.5%), and after 6 months of taking the drug no patient noted the profuse nature of menstruation. Before the start of taking COC with drospirenone, 57.9% of women reported painful menstrual bleeding. Against the background of taking the contraceptive within 3 months, this complaint was stopped in all patients. Sufficient efficacy of treatment of androgen dependent dermopathy in young women with the help of a microdosed drospirenone-containing combined oral contraceptive is estimated from the dermatological acne index. The analysis of the SAN questionnaire made it possible to reveal the improvement in the psychoemotional state of patients on the background of taking the drug. The conclusion. The results obtained proved the effectiveness and safety of the microclinized COC Dimia®. The drug has no significant effect on body weight, blood pressure, provides reliable control of the cycle and a decrease in menstrual bleeding, which results in stabilization of iron metabolism in the body. Dimia® is effective in the treatment of androgen-dependent dermopathy and can be recommended to young women for starting contraception.
