Effects of two estroprogestins containing ethynilestradiol 30g and drospirenone 3mg and ethynilestradiol 30g and chlormadinone 2mg on skin and hormonal hyperandrogenic manifestations

Hyperandrogenic manifestation in women, such as seborrhea, acne and increased hair growth are common reasons of psychological distress. Skin appearance is very important for young women. This study evaluated the hormonal and skin effects of two estroprogestins (EPs) containing ethinyl-estradiol (EE) 30g associated with drospirenone (DRSP) 3mg or chlormadinone acetate (CMA) 2mg, respectively. Fifty-five women with signs and symptoms of hyperandrogenism (seborrhea, acne and increased hair growth) were enrolled in the study; randomly, 30 women were treated with EE 30g + DRSP 3mg and 25 with EE 30g + CMA 2mg. Follicle-stimulating hormone (FSH), luteinising hormone (LH), 17-hydroxyprogesterone (17OHP), androstenedione (A), testosterone (T), dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG) and free androgen index (T100/SHBG, FAI) were assessed at baseline, and after 3 and 6 months of treatment with EPs. Effects on seborrhea, acne and increased hair growth (as Ferriman-Gallwey score) were also evaluated at the same time points. Finally, skin hydration, transepidermal water loss (TEWL) and skin homogeneity were studied with non-invasive technique during the study. Treatment for 6 months with both EPs decreased significantly the circulating androgen levels (A, T, DHEAS) and FAI, and increased SHBG levels; also skin pattern was improved. EP containing EE and DRSP was better than EP containing EE and CMA as for skin changes, as seborrhea, acne, increased hair, hydration, homogeneity and overall quality of the skin; moreover, hormonal changes (as FAI) under therapy were more pronounced with EE/DRSP than EE/CMA. These effects may be considered in EP choice and could be important in improving patient's compliance and quality of life in hyperandrogenic women.
