Assessment of serum hormone levels in female patients with acne vulgaris

Introduction: Acne is a chronic inflammatory disorder of the pilosebaceous unit with differential pathogenesis. And hormone plays a part role in the pathogenesis of acne. The objective of this study was valuation of the serum testosterone, estradiol, progesterone levels in women with acne vulgaris. 

Methods: We conducted a cross-sectional study and 175 women with acne vulgaris were examined, their serum estradiol, progesterone, testosterone were analyzed by chemiluminescence technique and compared with the healthy control group. 

Results: Increased serum hormone levels in women with acne vulgaris were accounted for 29.7%, and hyperandrogenism was accounted for 16.0% of cases. We found significant differences in testosterone levels (mean value, 55.67±25.56 versus 38.37±10.16 ng/dL, p<0.05) respectively in the acne group and the control group. However, the estradiol level of the acne group (323.15±93.31 pmol/L) was lower than the control group (370±58.88 pmol/L) with p<0.05). No statistically significant differences were found for progesterone (0.60±0.38 versus 0.50±0.15 ng/mL, p>0.05) levels. Moreover, we did not find the relationship between serum hormone levels and the severity of acne vulgaris. 

Conclusion: This study showed that the female acne vulgaris patients may have high serum testosterone levels and low serum estradiol levels compared with those of female controls. However, hormone alterations had no correlation with the acne grades.
