Elevated free testosterone levels in women with acne

Area of Science:

• Endocrinology
• Dermatology

Background:

• Hyperandrogenism is a common concern in female patients presenting with acne.
• Assessing androgen levels is crucial for diagnosing underlying conditions.

Purpose of the Study:

• To investigate if free testosterone is a more sensitive biomarker for hyperandrogenism in women with acne compared to total testosterone.
• To identify potential clinical indicators correlating with elevated free testosterone levels.

Main Methods:

• Studied 24 female patients with acne and 24 age-matched controls.
• Measured both free and total testosterone levels in all participants.
• Assessed for clinical signs of hyperandrogenism such as hirsutism and irregular menstrual cycles.

Main Results:

• 11 out of 24 acne patients had elevated free testosterone, versus only 4 with elevated total testosterone.
• Mean free testosterone was significantly higher in acne patients (1.035 ng/dL) than controls (0.54 ng/dL).
• No clear morphologic clues, apart from hirsutism in three cases, predicted elevated free testosterone.

Conclusions:

• Free testosterone is a more sensitive indicator of hyperandrogenism in female acne patients than total testosterone.
• Elevated free testosterone levels in acne patients do not correlate with acne severity, type, or distribution.
• Further investigation may be needed to understand the clinical implications of elevated free testosterone in acne.
