Which laboratory/ultrasonographic parameters affect the severity of hirsutism?

BACKGROUND AND OBJECTIVES: Hirsutism is associated with other androgen-dependent signs/symptoms. This study was designed with the aim of a comprehensive investigation of laboratory and ultrasonographic findings in hirsute women and their probable association with the "severity" of the disease. PATIENTS AND METHODS: This cross-sectional study included 123 hirsute women. Comprehensive medical history of each patient was recorded, and a broad physical examination was performed by a single dermatologist. Ferriman-Gallwey score was used to evaluate the hirsutism severity. Pelvic ultrasonography was done by a single radiologist for each patient, and serum levels of the follicular stimulating hormone (FSH), luteinizing hormone (LH), LH/FSH ratio, prolactin, thyroid-stimulating hormone, total testosterone, dehydroepiandrosterone sulfate, 17-alpha-hydroxyprogesterone, and cortisol were measured. The association of hirsutism severity and these paraclinical parameters was investigated. RESULTS: A statistically significant association was observed between polycystic ovary disease (PCOD) and the severity of hirsutism. A past medical history of PCOD was found to cause more severe forms of hirsutism in the involved patients as well. The presence of hormonal abnormalities was also significantly associated with the severity of hirsutism. CONCLUSIONS: More than half of the hirsute patients have endocrine abnormalities and/or PCOD. These two disorders are associated with the severity of hirsutism.
