Adult female acne: Clinical characteristics and factors significantly associated with polycystic ovary syndrome

Characterizing clinical and hormonal profiles of acne in north African women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the leading endocrine disorder in young women of childbearing age. Dermatological issues, particularly acne, are a major reason for medical consultations. The aim of this study is to determine the prevalence of PCOS in patients presenting with acne as their main dermatological complaint and to compare the metabolic and hormonal clinical characteristics of acne patients with PCOS to those with isolated acne. This was a prospective study with analytical aims, carried out in the Endocrinology Department and the Dermatology Department of Farhat Hached University Hospital in Sousse. The study included patients seeking treatment for acne from January 2023 to January 2024, divided into two groups: those with confirmed PCOS (G1) and those with isolated acne (G2). All patients underwent hormonal assessment and ovarian ultrasound. We conducted a study involving 212 patients. We found that 65.6% of acne patients had been diagnosed with PCOS. Nodular lesions were significantly more frequent in 'PCOS' (p = 0.02). Acne was linked with hirsutism, which was more prevalent in 'PCOS' (94.2% 'PCOS' vs. 67.1% 'isolated acne'), as well as androgenic alopecia (51% 'PCOS' vs. 21.9% 'isolated acne') (p < 10- 3). 'PCOS' showed evidence of biological hyperandrogenism, with a mean testosterone level of 0.72 ± 0.27 ng/mL, significantly higher than in 'isolated acne'. The LH/FSH ratio was greater than 1 in 72.7% of cases in 'PCOS', demonstrating a significant difference compared to 'isolated acne', where it was greater than 1 in 24.7% of cases (p < 10- 3). In our study, acne in 'PCOS' appeared to be more severe and was associated with hypertestosteronemia (p = 0.041) and hyperprolactinemia (p = 0.008). According to our results, phenotype A was the most likely to cause severe acne (p = 0.043). Our work is unique in that it brings to light this hidden aspect of the dermatological impact of PCOS, prompting physicians to screen for this endocrine disorder in all adult women seeking acne treatment.

Cutaneous Hormone Production Is Distinct between Anatomical Sites and between Males and Females

The skin acts as an endocrine organ capable of hormone production and response. Moreover, many skin conditions clinically improve with antiandrogen therapies. Despite their importance, we have an incomplete understanding of the composition of hormones produced by the skin. In this study, we have characterized the hormonal landscape of the skin across anatomical sites and between the sexes through analysis of skin secretions. In this observational pilot study, we collected skin secretions from the antecubital fossa, forehead, back, and axilla of 12 male and 10 female subjects using commercially available adhesive patches. We then developed a method to extract and quantify hormones from these secretions through liquid chromatography-tandem mass spectrometry. We were able to detect seven hormones and observed anatomical site differences in glucocorticoids, cortisone, and 11-deoxycorticosterone. Most notably, we observed marked elevations in dehydroepiandrosterone in the axilla and androstenedione on the forehead. We also detected differences in several sex steroid hormones between male and female subjects, with the majority consistent with known systemic hormone differences. Through this approach, future studies will determine how hormonal composition of skin secretions is altered in skin diseases.

Potential role of endoplasmic reticulum stress in the pathophysiology of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is an endocrine disorder that affects million women worldwide, presenting a complex pathophysiology that has not been fully elucidated yet. Recently, it has been suggested that PCOS triggers the endoplasmic reticulum (ER) stress, thus being associated with unfolded protein response (UPR) activation. Indeed, the UPR response has been associated with several pathological conditions, including in the reproductive system. Several studies demonstrated that ovarian UPR markers are upregulated in PCOS, being associated with worst ovarian outcomes, and this was ameliorated by ER stress inhibition. In this review, we aim to summarize the main findings from previous studies covering this topic, in an attempt to clarify the potential role of ER stress and the UPR response in the pathophysiology of PCOS.
