https://www.selleckchem.com/products/nik-smi1.html Background Acne vulgaris is a common dermatologic disease that causes significant social and psychological morbidity. Isotretinoin, as a vitamin A derivative, is the most effective agent in the treatment of acne. Evidence suggests that isotretinoin's therapeutic function is independent of hormonal mediation; however, the effect of isotretinoin on serum androgens and precursor androgen levels in humans remains unclear. Objective Herein, we aim to investigate the effect of low-dose isotretinoin on androgen levels in women and postulate the role of concomitant anti-androgen therapy (e.g., spironolactone). Methods A total of 36 women, age 18 to 30 years, with moderate-to-severe nodulocystic acne were treated with 20 mg isotretinoin (Roaccutane) daily for 3 months. A hormone panel was obtained at baseline and after completion of the treatment course. The panel included dehydroepiandrosterone (DHEA), 17-hydroxyprogestrone, testosterone, free testosterone, dihydrotestosterone (DHT), luteinizing hormone, follicle stimulating hormone, and prolactin. Results Serum levels of testosterone (p = .015), prolactin (p = .001), and DHT (p = .001) were significantly decreased, while serum levels of DHEA (p = .001) significantly increased after isotretinoin treatment. No significant change was found in the other hormones evaluated. Limitations The distribution of acne was not assessed in our patient population. We did not directly evaluate for associations between elevated DHEA levels and clinical response rates. Conclusion Isotretinoin alone can decrease androgen levels, but increase an important driver of acne pathogenesis (i.e., DHEA). The co-administration of an anti-androgenic agent (e.g., spironolactone) may optimize the therapeutic efficacy of isotretinoin by limiting iatrogenic increases in DHEA and perhaps allow for more widespread use of low-dose isotretinoin. © 2019 Published by Elsevier Inc. on behalf of Women's Dermatologi
