Effects of isotretinoin on body mass index, serum adiponectin, leptin, and ghrelin levels in acne vulgaris patients

INTRODUCTION Isotretinoin has been successfully used for the treatment of acne vulgaris. AIM To investigate the effects of isotretinoin on body mass index (BMI), to determine whether isotretinoin causes any changes in serum adiponectin, leptin, and ghrelin levels in acne vulgaris patients, and to correlate variables. MATERIAL AND METHODS Thirty-two patients were included in this study. Oral isotretinoin was begun at a dose of 0.5-0.6 mg/kg and raised to 0.6-0.75 mg/kg. Pretreatment and posttreatment third-month BMI and adiponectin, leptin, and ghrelin serum levels were measured. RESULTS The pre- and posttreatment BMI values were not significantly different. In addition, serum adiponectin and leptin levels were significantly increased following isotretinoin therapy while serum ghrelin levels were not different. CONCLUSIONS Isotretinoin may exert its anti-inflammatory activity by increasing leptin and adiponectin levels.
