Abstract
OBJECTIVE This study aimed to elucidate the genetic aspects of the relationship between sex hormones and cutaneous melanoma risk, providing valuable insights into this complex association. METHODS In this study, we used estradiol, bioavailable testosterone, sex hormone-binding globulin, and total testosterone as the exposure and melanoma as the outcome for two-sample Mendelian randomization analysis. In this study, a random-effects inverse-variance weighting (IVW) model was used as the main analysis model, and the corresponding weighted median, simple mode, weighted mode, and Mendelian randomization‒Egger methods were used as supplementary methods. We assessed both heterogeneity and horizontal pleiotropy in our study, scrutinizing whether the analysis results were affected by any individual single nucleotide polymorphism. RESULTS The random-effects IVW method indicated that estradiol [odds ratio (OR), 1.000; 95% confidence interval (CI), 0.998-1.003; P = 0.658], bioavailable testosterone (OR = 1.001, 95% CI, 0.999-1.003; P = 0.294), sex hormone-binding globulin (IVW: OR, 1.000; 95% CI, 0.998-1.003; P = 0.658), and total testosterone (IVW: OR, 1.002; 95% CI, 0.999-1.005; P = 0.135) were not genetically linked to cutaneous melanoma. No analyses exhibited heterogeneity, horizontal pleiotropy, or deviations. CONCLUSION We were unable to find genetic evidence for a causal relationship between sex hormones and the occurrence of cutaneous melanoma in this study. These results are limited by sample size and population, so the causal relationship between sex hormones and cutaneous melanoma needs to be further studied.

Abstract
Males and females exhibit profound differences in immune responses and disease susceptibility. However, the factors responsible for sex differences in tissue immunity remain poorly understood. Here, we uncovered a dominant role for type 2 innate lymphoid cells (ILC2s) in shaping sexual immune dimorphism within the skin. Mechanistically, negative regulation of ILC2s by androgens leads to a reduction in dendritic cell accumulation and activation in males, along with reduced tissue immunity. Collectively, our results reveal a role for the androgen-ILC2-dendritic cell axis in controlling sexual immune dimorphism. Moreover, this work proposes that tissue immune set points are defined by the dual action of sex hormones and the microbiota, with sex hormones controlling the strength of local immunity and microbiota calibrating its tone.

Sardana K, Muddebihal A, Sehrawat M, Bansal P, Khurana A. An updated clinico-investigative approach to diagnosis of cutaneous hyperandrogenism in relation to adult female acne, female pattern alopecia & hirsutism a primer for dermatologists. Expert Rev Endocrinol Metab 2024; 19:111-128. [PMID: 38205927 DOI: 10.1080/17446651.2023.2299400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 12/21/2023] [Indexed: 01/12/2024]
Abstract
INTRODUCTION Hyperandrogenism is a clinical state consequent to excess androgen production by the ovary, adrenals, or increased peripheral conversion of androgens. The varied manifestations of hyperandrogenism include seborrhea, acne, infertility, hirsutism, or overt virilization of which adult female acne, hirsutism, and female pattern hair loss are of clinical relevance to dermatologists. AREAS COVERED We limited our narrative review to literature published during period from 1 January 1985 to Dec 2022 and searched PubMed/MEDLINE, Web of Science (WOS), Scopus, and Embase databases with main search keywords were 'Hyperandrogenism,' 'Female,' 'Biochemical,' 'Dermatological', and 'Dermatology.' We detail the common etiological causes, nuances in interpretation of biochemical tests and imaging tools, followed by an algorithmic approach which can help avoid extensive tests and diagnose the common causes of hyperandrogenism. EXPERT OPINION Based on current data, total testosterone, sex hormone binding globulin, DHEAS, prolactin, free androgen index, and peripheral androgenic metabolites like 3-alpha diol and androsterone glucuronide are ideal tests though not all are required in all patients. Abnormalities in these biochemical investigations may require radiological examination for further clarification. Total testosterone levels can help delineate broadly the varied causes of hyperandrogenism. Serum AMH could be used for defining PCOM in adults.

Abstract
In vitro studies show that 5α-androstane-3,17-dione (5α-A) is an important intermediate in the formation of dihydrotestosterone (DHT) from androstenedione (A) in women and men. Many studies involving hyperandrogenism, hirsutism, and polycystic ovary syndrome (PCOS) have measured A, testosterone (T), and DHT, but not 5α-A due to lack of a readily available assay to quantify this androgen. We have developed a specific and sensitive radioimmunoassay to measure 5α-A levels, together with A, T, and DHT, in both serum and genital skin. The present study involves 2 cohorts. Cohort 1 included 23 mostly postmenopausal women who provided both serum and genital skin to measure those androgens. In cohort 2, serum androgen levels were compared between women with PCOS and non-PCOS controls. Tissue-to-serum ratios were significantly higher for 5α-A and DHT as compared to A and T. None of the androgens showed a significant correlation between serum and genital tissue. In serum, 5α-A was significantly correlated with A, T, and DHT. In cohort 2, A, T, and DHT were significantly higher in the PCOS group compared to the control group. In contrast, 5α-A levels were similar between the 2 groups. Our findings support the view that 5α-A is an important intermediate in DHT formation in genital skin. Also, the relatively low levels of 5α-A in PCOS women suggest that it may play a more important intermediate role in the conversion of A to androsterone glucuronide.

Abstract
Hirsutism, which is characterized by excessive growth of terminal hair in a male pattern, may result from various causes including polycystic ovary syndrome (PCOS), non-classic congenital adrenal hyperplasia, adrenal or ovarian tumors or it may be idiopathic. Idiopathic hirsutism is currently defined as hirsutism associated with normal ovulatory function, normal serum androgen levels and normal ovarian morphology, however, the pathogenesis of idiopathic hirsutism is not clear. The androgens are the main hormones to stimulate growth of body hair, therefore, there should be any form of increased androgen effect irrespective of normal serum androgen levels in any patient with hirsutism. In accordance to this scientific truth, we have previously shown that, although within normal limits, patients with idiopathic hirsutism have relatively higher serum androgen levels (relative hyperandrogenemia) in comparison to healthy subjects which let as to think that is idiopathic hirsutism really idiopathic? In addition to relative hyperandrogenemia, we have previously shown that, in comparison to healthy subjects, women with idiopathic hirsutism demonstrated higher expression of steroid sulphatase and 17-beta hydroxysteroid dehydrogenase mRNA both in the subumbilical region and arm skin, which contributes to local androgen metabolism. Those results support the idea that, in some patients, although the adrenals or ovaries do not secrete increased amount of androgens leading to hyperandrogenemia, pilocebaceous unit locally produce increased amount of androgens leading to hirsutism without ovulatory dysfunction. Upon the demonstration of relative hyperandrogenemia and possible increase in local androgen synthesis in patients with idiopathic hirsutism, we think that idiopathic hirsutism is not idiopathic and it may be named as “normoandrogenic hirsutism”. Furthermore, it may not be a different entity but may be an early stage of hyperandrogenic disorders such as PCOS. Clinically, this can be find out by following-up patients with idiopathic hirsutism prospectively.

Abstract
The association between acne and insulin resistance has not been investigated as thoroughly in males as it has been in women, despite the fact that in adult men, acne prevalence has grown. On the face, sebaceous glands produce and secrete sebum, which lubricates the skin and protects it from friction. Metformin, an insulin-sensitizing medication, may modify the association between acne vulgaris and insulin resistance (IR). Individuals with IR, metabolic syndrome or with impaired glucose tolerance are sometimes treated 'off label' with Metformin. In these conditions, IR may be a leading factor in the pathogenesis of acne, and in men, Metformin treatment may reduce the Global Acne Grading System (GAGS) score by enhancing insulin sensitivity. However, additional clinical studies are required to corroborate these assumptions.

Abstract
The challenge for the treatment of severe traumas poses an urgent clinical need for the development of biomaterials to achieve rapid hemostasis and wound healing. In the past few decades, active inorganic components and their derived composites have become potential clinical products owing to their excellent performances in the process of hemorrhage control and tissue repair. In this review, we provide a current overview of the development of inorganic-based biomaterials used for hemostasis and wound healing. We highlight the methods and strategies for the design of inorganic-based biomaterials, including 3D printing, freeze-drying, electrospinning and vacuum filtration. Importantly, inorganic-based biomaterials for rapid hemostasis and wound healing are presented, and we divide them into several categories according to different chemistry and forms and further discuss their properties, therapeutic mechanisms and applications. Finally, the conclusions and future prospects are suggested for the development of novel inorganic-based biomaterials in the field of rapid hemostasis and wound healing.

Abstract
This study aimed to develop microemulsions using poloxamer 124 as a surfactant to improve the skin penetration of finasteride and to investigate the skin penetration pathways of these microemulsions by colocalization techniques using confocal laser scanning microscopy (CLSM). The prepared finasteride-loaded microemulsions had average particle sizes ranging from 80.09 to 136.97 nm with particle size distributions within acceptable ranges and exhibited negative surface charges. The obtained microemulsions could significantly increase the skin penetration of finasteride compared to a finasteride solution. According to the skin penetration pathway evaluation conducted with CLSM, the microemulsions were hair follicle-targeted formulations due to penetration via the transfollicular pathway as a major skin penetration pathway. Additionally, this study found that the microemulsions also penetrated via the intercluster pathway more than via the intercellular pathway and transcellular pathway. The intercluster pathway, intercellular pathway, and transcellular pathway were considered only minor pathways.

Abstract
Androgenic alopecia (AGA) is a common disease that negatively affects patients’ physical and mental health. AGA can be treated with drugs that improve the perifollicular microenvironment, such as 5α-reductase inhibitors (e.g., dutasteride [DUT]), androgen receptor blockers, and minoxidil. However, the efficacy of these treatments is limited. Therefore, this study aimed to show that nanoparticles are effective as stable carriers with high curative benefits and little adverse effects. The in vitro study showed that PLGA-DUT/siAR@DPCM NPs could deliver both DUT and siAR to dermal papilla cells. They could successfully suppress 5α-reductase and knock down androgen receptor, respectively, and thereby promote cell proliferation. In the in vivo study, PLGA-DUT/siAR@DPCM NPs showed a significant therapeutic effect in an AGA mouse model. They successfully penetrated the stratum corneum and showed a clear targeting effect on hair follicles and surrounding tissues. PLGA-DUT/siAR@DPCM NPs could enable the targeted delivery of DUT and siAR through percutaneous penetration, enhancing phagocytosis and decreasing adverse effects. Thus, they have great potential in the clinical treatment of AGA.

Abstract
BACKGROUND Melanoma is associated with poor prognosis in its advanced stages. Potential influence of estrogen and its metabolites on melanoma growth has been suggested. AIMS The objective of this review was to provide an overview on the evidence related to estrogen in malignant melanoma. MATERIALS AND METHODS Literature search using PubMed, Google Scholar and relevant cross-references of the retrieved articles was performed to review relevant published articles related to estrogen and its effects in malignant melanoma. RESULTS Effect of estrogen signaling on a tissue largely depends on the relative expression of estrogen receptors (ER) α and β. Gender differences in melanoma may be explained by the difference in expression of these receptors. ERβ is the principal ER in melanoma. DISCUSSION Although there is uncertainty about role of estrogen in pathogenensis and progression of melanoma, evidence suggests that its growth and metastasis are influenced by estrogen stimulation. Role ER on the proliferation of melanoma cells is well described. CONCLUSION There is a need of safe and effective therapy for melanoma, especially for advanced cases. After the establishment of specific role of estrogen and its receptor, analysis of specific genetic mutation can be performed for proper utilization of targeted therapies.

Abstract
Skin being the largest organ of the body, is equipped with numerous functional properties. Over the past few years, intricate research into the biology of skin has led to a gamut of discoveries. Skin is now regarded as one of the most vital endocrine organs. The skin contains equivalents of the hypothalamo-pituitary-adrenal axis, hypothalamo-pituitary-thyroid axis and the appendages produce multiple hormones such as Vitamin D, sex steroids, retinoids and opioids. In this article, we will explore the role of skin as a target and source of some of the hormones of the human body, and briefly touch on the clinical applications.

[PMID: 35328552 PMCID: PMC8955788 DOI: 10.3390/ijms23063132] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 03/09/2022] [Accepted: 03/11/2022] [Indexed: 12/23/2022] Open
Abstract
The skin exerts several fundamental functions that are the first physical, chemical and immune barriers to the human body. Keratinocytes, the main cell type of the epidermis, provide mechanical defense, support skin integrity and actively endorse cutaneous immune responses. Not surprisingly, considering these crucial activities, alterations in keratinocyte functions are associated with different inflammatory skin diseases. Recent findings indicate that the skin should not only be regarded as a target for hormones but that it should also be considered as an endocrine peripheral organ that is directly involved in the synthesis and metabolism of these chemical messengers. Sex hormones have multiple effects on the skin, attributed to the binding with intracellular receptors expressed by different skin cell populations, including keratinocytes, that activate downstream signaling routes that modulate specific cellular functions and activities. This review is aimed at reorganizing the current knowledge on the role exerted by sex hormones on keratinocyte function in five different inflammatory skin diseases: Hidradenitis suppurativa; Acne vulgaris; Atopic dermatitis; progesterone hypersensitivity; psoriasis. The results of our work aim to provide a deeper insight into common cellular mechanisms and molecular effectors that might constitute putative targets to address for the development of specific therapeutic interventions.

Abstract
The intense pulsed light (IPL) therapy has three mechanisms of action in acne vulgaris: photochemical, photoimmunological, and photothermal. In this clinical trial, 47 patients with facial inflammatory acne lesions, ages ranging from 15 to 40 years, were enrolled. Patients were categorized into two groups: (a) 20 patients in Group A treated with IPL for 3 sessions, 3 weeks apart, (b) and 27 patients in Group B treated with benzoyl peroxide (BPO) 2.5% gel daily at night for 9 weeks. Follow up was done at 3 weeks after the end of treatment. The effect of treatment was evaluated objectively according to total lesion counting and digital photographic assessment and subjectively according to the patients' satisfaction. IPL is an effective and well-tolerated method for the treatment of inflammatory facial acne like BPO. Therefore, the IPL can be used as a standard therapy for inflammatory acne vulgaris.

Abstract
Hidradenitis suppurativa is a cutaneous chronic inflammatory disease that is estimated to affect about 1% of the population and caused pain, malodorous discharge, disfigurement, and poor quality of life with psychosocial problems. The typical features are recurrent painful nodules, abscesses, and sinus tracts on the axillae, groins, gluteal areas, and anogenital regions since postpuberty. Smoking and obesity are two major triggering factors of hidradenitis suppurativa. Women are prone to have hidradenitis suppurativa than men in Western countries, but the male-to-female ratio is reversed in oriental countries. The disease severity can be affected by menstruation, pregnancy, and menopause. Furthermore, the phenotypes are different among men and women with hidradenitis suppurativa. Men are prone to have buttock involvement while women are prone to have axillary, groins, and submammary lesions. This review introduces the skin appendages and pathophysiology of hidradenitis suppurativa and then focuses on the sex difference and the effects of sex hormones on hidradenitis suppurativa and current hormone-associated treatments.

Abstract
INTRODUCTION The efficacy of clascoterone cream was demonstrated in two phase three vehicle-controlled clinical trials that enrolled over 1,400 subjects. Its safety profile allowed it to be approved for treating patients as young as 12 years old. During clinical trials, the occurrence of local skin reactions (edema, erythema, pruritus, dryness) was similar to treatment with vehicle alone. AREAS COVERED All publications describing the clinical development of clascoterone cream (cortexolone 17α-propionate) are reviewed and discussed in relation to with existing topical and systemic therapies for acne vulgaris. EXPERT OPINION Clascoterone 1% cream is a novel first-in-class topical androgen receptor inhibitor for the treatment of acne vulgaris. Topical clascoterone 1% cream represents the first new type of therapy for acne treatment in almost 40 years and may become first-line therapy.

Abstract
BACKGROUND Mechanisms involved in hair metabolism are diverse, and the availability of ingredients that normalize dysfunctions or mitigate the effects of extrinsic stress suffered daily is greatly desired by consumers to improve the aesthetic appearance of hair. AIMS In this work, we carried out a preclinical exploratory approach to evaluate the effects of a complex of nanoencapsulated active ingredients (AcPi), as well as a cosmetic formulation containing AcPi (ShPi and HtPi) in mechanisms involving hair loss and follicular aging. METHODS Human hair follicle dermal papilla cells and human scalp culture were treated with AcPi, ShPi, or HtPi and stimulated with UV radiation or testosterone for further measurement of mitochondrial biogenesis, reactive oxygen species (ROS), β-catenin, dyhidrotestosterone (DHT), collagen XVIIα1 (COL17A1), and cutaneous permeation. RESULTS Our results demonstrated that AcPi prevents oxidative stress and balances mitochondial activity disturbed by exposure to UV radiation. AcPi also promoted an enrichment of WNT/β-catenin signaling pathway, stimulating hair growth, and lengthening the anagen phase of hair cycle. ShPi and HtPi were able to prevent hair aging, minimizing the excessive degradation of COL17A1 in hair follicle exposed to UV radiation, in addition to controlling androgenic metabolism by reducing DHT production. CONCLUSION The integral effects of AcPi have not been completely elucidated; however, these results, associated with clinical evidences, allow us to infer that this ingredient prevents follicular aging, miniaturization, and consequently hair loss by mechanisms involving energetic homeostasis maintenance, antioxidant, and anti-androgenic actions.

Abstract
BACKGROUND Although some studies in the literature report that autologous and homologous platelet-rich plasma (PRP) can be employed in the treatment of androgenic alopecia (AGA), no study, to the authors' knowledge, has examined the estrogen concentration of prepared PRP. OBJECTIVES The authors aimed to determine the presence of estrogen in PRP and to investigate the effect of estrogen concentration of PRP on AGA treatment. METHODS Between 2017 and 2018, 30 male patients with hair loss complaints were included in this prospective study. Autologous PRP was injected in patients in Group 1. Homologous PRP with high estrogen levels was injected in the patients in Group 2. PRP was injected in both groups 4 times at 0, 1, 3, and 6 months. The obtained photographs were evaluated and hair densities of each patient at controls were calculated. RESULTS The mean estrogen level measured in PRP was statistically significantly higher in Group 2. In both groups, the increase in hair density was observed from the first month, but this increase was statistically significantly higher in all controls in Group 2. In Group 2, there was a statistically significant increase in the 1st and 3rd months compared with the previous control, but there was no difference between the 6th and 12th months and the 3rd month. CONCLUSIONS Increased hair density is greater and earlier in the group receiving estrogen-rich PRP than in the group utilizing autologous PRP. The authors think that estrogen-rich PRP may be employed in the treatment of AGA in the presence of an appropriate donor. LEVEL OF EVIDENCE: 2

Abstract
Acne vulgaris is a very common pilosebaceous inflammatory disease occurring primarily on the face and also rare on the upper arms, trunk, and back, which is caused by Propionibacterium, Staphylococcus, Corynebacterium, and other species. Pathophysiology of acne comprises of irregular keratinocyte proliferation, differentiation, increased sebum output, bacterial antigens and cytokines induced inflammatory response. Treatment of acne requires proper knowledge on the pathophysiology then only the clinician can come out with a proper therapeutic dosage regimen. Understanding the pathophysiology not only includes the mechanism but also involvement of receptors. Thus, this review is framed in such a way that the authors have focused on the disease acne vulgaris, pathophysiology, transcription factors viz. the Forkhead Box O1 (FoxO1) Transcription Factor, hormones like androgens and receptors such as Histamine receptors, Retinoic receptor, Fibroblast growth factor receptors, Toll like receptor, Androgen receptor, Liver X-receptor, Melanocortin receptor, Peroxisome proliferator-activated receptor and epidermal growth factor receptors involvement in the progression of acne vulgaris.

Abstract
BACKGROUND Excessive androgenesis in the skin promotes sebaceous hyperproduction which is the onset of acne vulgaris pathogenesis. Free fatty acids and lipid accumulation in the glandular infundibulum culminates in microbiota imbalance, triggering inflammatory response and follicular hyperkeratinization. AIMS The purpose of this work was to present an alternative cosmetic treatment for acne skin care, focusing on the prevention of sebaceous gland dysregulation. METHODS Insulin-stimulated human sebocytes were treated with noncytotoxic concentrations of a DTRW cosmetic formulation. After 6 days of incubation, cell lysates were collected for testosterone, 5α-reductase, and dyhidrotestosterone (DHT) quantitation. In parallel, cells were stained with Oil Red O to measure sebum production. RESULTS Human sebocytes were incubated with insulin to mimic a seborrheic microenvironment with overproduction of intracellular lipids and fatty acids. Concomitant incubation of cell cultures with DRTW was able to promote a 52.97% reduction in intracellular lipid content. The anti-androgenic properties of DRTW had been proved by the reductions of testosterone (↓59.90%), 5α reductase (↓59.34%), and DHT (↓55.98%) levels in sebocyte cultures also stimulated with insulin. CONCLUSION The results indicate a promising action of DRTW cosmetic formulation in preventing the development of acne lesions by mechanisms involving the modulation of cutaneous androgenesis and consequently the control of sebum overproduction, considered one of the leading causes of acne.

Abstract
Sweat secretion keeps feet and insoles humid and rich in nutrients, which are the conditions needed to maintain abundant microbial growth. Analyzing the diversity and function of microorganisms in the insole is of great significance in the development of functional insoles and prediction of human foot hygiene condition. In this study, pure culture method, MiSeq high-throughput sequencing technology, and PICRUSt gene function prediction were used to analyze the diversity and function of the bacterial community from insoles of healthy population of different sexes and age groups. Staphylococcus, Micrococcus, and Brevibacterium are present in all insole samples, and there is no significant difference between sexes of the same age group. However, a significant difference in insole microbial population was obtained among age groups. For community function, all six samples expressed similarity in the preliminary metabolism, but in samples from the elderly, many specific catabolic genes were associated with human disease and drug resistance. This study provides a reference for the development of multi-function insoles and other sanitary products for disease prediction in a healthy population.

Abstract
BACKGROUND Hidradenitis suppurativa/acne inversa is a disease with deep-seated chronic painful nodules, abscesses, and draining sinus tracts, which manifests on the apocrine gland-rich skin areas of the body. Observational findings demonstrate that the disease usually appears after puberty, exhibits pre-menstrual flares in women, improves in pregnancy, and worsens post-partum, which indicates a role of hormones and particularly of androgens in its pathophysiology. Because increased androgen levels in serum have not been widely reported, an end-organ androgen hypersensitivity has been postulated. OBJECTIVE The aim of this systematic review was to identify and present evidence for antiandrogen therapeutic options for the treatment of hidradenitis suppurativa/acne inversa. METHODS A literature search was conducted in different medical electronic databases using the keywords "hidradenitis", "suppurativa", "acne inversa", and "antiandrogen" on 1 December, 2018. The main therapeutic options were subsequently used as separate keywords with the disease terms in a separate search. RESULTS The main therapeutic options yielded were cyproterone acetate, spironolactone, finasteride, and metformin. One randomized controlled crossover trial and seven case series were identified following use of a standard extraction form for eligibility. CONCLUSION The existing studies do not allow a robust evidence-based recommendation for the use of antiandrogens in the treatment of hidradenitis suppurativa/acne inversa. Further randomized controlled trials are needed to define the role of hormonal treatment as an alternative or concomitant therapy together with antibiotics or biologics.

Abstract
BACKGROUND Bimagrumab is a human monoclonal antibody inhibitor of activin type II receptors (ActRII), with anabolic action on skeletal muscle mass by blocking binding of myostatin and other negative regulators of muscle growth. Bimagrumab is under evaluation for muscle wasting and associated functional loss in hip fracture and sarcopenia, and in obesity. Bimagrumab also blocks other endogenous ActRII ligands, such as activins, which act on the neurohormonal axes, pituitary, gonads and adrenal glands. AIM To evaluate the effect of bimagrumab on the pituitary-gonadal and pituitary-adrenal axes in humans. METHODS Healthy men and women, aged 55 to 75 years, received bimagrumab intravenously 10 mg/kg or placebo on Day 1 and Day 29. Pituitary-gonadal and pituitary-adrenal functions were evaluated with basal hormone measurement and standard gonadotropin-releasing hormone (GnRH) and adrenocorticotropic hormone (ACTH) stimulation tests at baseline, Week 8 and at the end of study (EOS)-Week 20. RESULTS At Week 8, follicle-stimulating hormone (FSH) levels were reduced by 42.16 IU/L (P < .001) and luteinizing hormone (LH) levels were increased by 2.5 IU/L (P = .08) over placebo in response to bimagrumab in women but not in men. Effects that were reversible after bimagrumab was cleared. Gonadal and adrenal androgen levels were not affected by exposure to bimagrumab. CONCLUSION Bimagrumab alters the function of pituitary gonadotroph cells, consistent with blockade of activin on local ActRII. This effect is reversible with clearance of bimagrumab. Bimagrumab did not impact gonadal and adrenal androgen secretion.

Beyond sexual functions, androgens exert their action in skin physiology and pathophysiology. Skin cells are able to synthesize most active androgens from gonadal or adrenal precursors and the enzymes involved in skin steroidogenesis are implicated both in normal or pathological processes. Even when the role of androgens and androgen receptor (AR) in skin pathologies has been studied for decades, their molecular mechanisms in skin disorders remain largely unknown. Here, we analyze recent studies of androgens and AR roles in several skin-related disorders, focusing in the current understanding of their molecular mechanisms in androgenetic alopecia (AGA). We review the molecular pathophysiology of type 2 5α-reductase, AR coactivators, the paracrine factors deregulated in dermal papillae (such as TGF-β, IGF 1, WNTs and DKK-1) and the crosstalk between AR and Wnt signaling in order to shed some light on new promising treatments.

Abstract
Acne is a multifactorial and inflammatory disease of pilosebaceous follicles, which affects most adolescents. Recent epidemiological data revealed a difference in adults affected by this disease. Women have a high prevalence and incidence when compared with men, especially after 25 years of age. In contrast to what was initially thought, most of these patients do not present endocrinopathy capable of leading to the development of the lesions. When present, polycystic ovarian syndrome is the main cause. However, in these cases, acne is rarely the only dermatological manifestation; hirsutism and acanthosis nigricans are often present. The majority of the normoandrogenic acne patients present a history since adolescence, but in many cases the lesion distribution and intensity change with time. There is often a typical localization of the lesions in the lower third of the face and lateral region of the neck. Another interesting feature is related to the impact on quality of life (QoL), which is always intense. Often there are signs of depression, even when the lesions are mild. As most adult patients are women, in addition to the conventional options, there is also hormone treatment. Combined oral contraceptives and spironolactone are good options. Knowing more about the particularities in etiopathogenesis, impact on QoL, and specific treatment options is important to all dermatologists who face the challenge of treating acne in adults.

Abstract
Cortexolone-17α-propionate (CP) is a topically active antiandrogen useful in the treatment of skin disorders. In the solid state, three anhydrous forms of this drug (CPI, CPII and CPIII) occur, together with one hydrated crystal (CPW). The single crystal structure of the monohydrated phase, CPW, compared with that of the anhydrous form CPIII, shows a markedly different solid state behavior. These latter pseudopolymorphic forms have also been fully characterized by spectroscopic methods.

Abstract
The treatment of acne, especially severe acne, remains a challenge to dermatologists. Therapies include retinoids, antibiotics, hormones, lights, lasers, and various combinations of these modalities. Acne is currently considered a chronic rather than an adolescent condition. The appropriate treatment depends on the patient and the severity of disease. The purpose of this study was to review current therapies for acne of all severities and to introduce the 650-μs 1064-nm laser for the treatment of acne.

Abstract
INTRODUCTION Despite the impressive increase of knowledge on acne etiology accumulated during the last 20 years, few efforts have been overtaken to introduce new therapeutic regiments targeting the ideal treatment of acne. The increasing emergence of microbial resistance associated with antibiotics, teratogenicity, particularly associated with systemic isotretinoin, and the need for an adverse drug profile, which can be tolerated by the patient, make the need of new pathogenesis relevant anti-acne agents an emerging issue. Areas covered: A search for phase 1 and 2 acne treatment trials in the US National Institutes of Health database of clinical trials and the European Medicines Agency database with the key words 'acne' and 'treatment' was carried out, on 6 January 2017. Expert opinion: The detected trials mostly investigate topical agents that may act via sebosuppressive effects, antimicrobial properties or anti-inflammatory actions. The compounds under investigation include olumacostat glasaretil, cortexolone 17α-propionate, stearoyl-CoA desaturase 1 inhibitors, agents affecting the melanocortin system, omiganan, and minocycline. Systemic studied anti-acne drugs include finasteride, biologics, low dose anti-inflammatory antibiotics, and leukotriene B4 inhibitors.

Abstract
BACKGROUND Gender is one of the most significant factors that influence facial anatomy and behavior, both key factors in the aging process. OBJECTIVE To review male facial anatomy, physiology, and behavior and how it contributes to sexual dimorphism in facial aging. METHODS A MEDLINE search was performed for publications on gender differences in facial anatomy, aging, cutaneous physiology, and behavior. RESULTS There are differences in both intrinsic and extrinsic aging factors in men. Men have a thicker epidermis and dermis with more active cutaneous appendages including hair growth. Male skin has a reduced antioxidant capacity and increased ultraviolet-induced immunosuppression. The male face is larger and has a unique square shape with less subcutaneous soft tissue, especially at the medial cheek. Men are also more prone to smoking and exhibiting poor sun-protective behavior. The differences in intrinsic and extrinsic aging factors contribute to poor facial aging in men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss. CONCLUSION This review provides insight into the factors contributing to accelerated male facial aging. Understanding gender differences in aging will help physicians tailor cosmetic treatments for men and minimize extrinsic aging factors.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is characterized by a combination of hormonal and metabolic disturbances, such as insulin resistance, glucose intolerance, anovulation and hyperandrogenism. Clinical phenotypes of PCOS show different patterns of steroid hormones that have been investigated to some extent. This study aimed to establish a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantification of salivary testosterone and androstenedione and to describe the salivary testosterone-to-androstenedione (T/A4) ratio as a new tool for the assessment of hyperandrogenism and metabolic health. MATERIAL AND METHODS Saliva and serum samples of 274 patients with PCOS and 51 healthy women were used for the quantification of steroid hormones. A comprehensive clinical and metabolic assessment was performed. Salivary testosterone and androstenedione were measured via LC-MS/MS. The salivary T/A4 ratio was calculated and correlated with hormones and metabolic parameters. RESULTS Salivary testosterone (P < 0·001), androstenedione (P < 0·001) and the salivary T/A4 ratio (P < 0·001) were significantly higher in patients with patients compared to healthy women. In patients with PCOS, a high salivary T/A4 ratio was associated with an adverse metabolic phenotype, that is glucose intolerance (P = 0·019), insulin resistance (P < 0·001), metabolic syndrome (P < 0·001), obesity (P < 0·001) and oligo-/anovulation (P = 0·001). Significant correlations of the salivary T/A4 ratio with adverse metabolic parameters were found. CONCLUSION Quantification of salivary androgens provides an attractive alternative to serum analysis and helps in characterizing metabolic health in women with PCOS. Our data show a strong link between a high salivary T/A4 ratio and an adverse metabolic phenotype in patients with PCOS.

Abstract
BACKGROUND Gender disparity in melanoma outcome is consistently observed, suggesting that gender is as an important prognostic factor. However, the source of this gender disparity in melanoma remains unclear. OBJECTIVE This article reviews advances in our understanding of gender differences in melanoma and how such differences may contribute to outcomes. METHODS A broad literature search was conducted using the PubMed database, with search terms such as 'gender differences in melanoma' and 'sex differences in melanoma.' Additional articles were identified from cited references. RESULTS Herein, we address the gender-linked physiologic differences in skin and melanoma. We discuss the influence of estrogen on a woman's risk for melanoma and melanoma outcomes with regard to pregnancy, oral contraceptives, hormone replacement therapy, and UV tanning. CONCLUSIONS The published findings on gender disparities in melanoma have yielded many advances in our understanding of this disease. Biological, environmental, and behavioral factors may explain the observed gender difference in melanoma incidence and outcome. Further research will enable us to learn more about melanoma pathogenesis, with the goal of offering better treatments and preventative advice to our patients.

Abstract
PCOS is a clinical heterogeneous entity of female androgen excess diagnosed by exclusion of other disorders responsible for androgen excess. The concept of secondary PCOS implies that there is a primary well-defined cause leading to the PCOS phenotype with underlying androgen overproduction, regardless of the origin. In these cases, we presume the term of 'secondary PCOS' could be used. In all these conditions, the potential complete recovery of the hyperandrogenemic state as well as the remission of the PCOS phenotype should follow the removal of the cause. If accepted, these concepts could help clinicians to perform in-depth investigations of the potential factors or disorders responsible for the development of these specific forms of secondary PCOS. Additionally, this could contribute to develop further research on factors and mechanisms involved in the development of the classic and the nonclassic PCOS phenotypes.

Abstract
Cholesterol and sex steroid hormones including androgens and estrogens play a critical role in the development and progression of urological diseases such as prostate cancer. This disease remains the most commonly diagnosed malignant tumor in men and is the leading cause of death from different cancers. Attempts to understand the role of cholesterol and steroid metabolism in urological diseases have been ongoing for many years, but despite this, our mechanistic and translational understanding remains elusive. In order to further evaluate the problem, we have taken an interest in metabolomics; a discipline dedicated to the systematic study of biologically active metabolites in cells, tissues, hair and biofluids. Recently, we provided evidence that a quantitative measurement of cholesterol and sex steroid metabolites can be successfully achieved using hair of human and mouse models. The overall goal of this short review article is to introduce current metabolomic technologies for the quantitative biomarker assay development and also to provide new insight into understanding the underlying mechanisms that trigger the pathological condition. Furthermore, this review will place a particular emphasis on how to prepare biospecimens (e.g., hair fiber), quantify molecular profiles and assess their clinical significance in various urological diseases.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder of unknown etiology. The role of hormones in HS remains unclear, but the observation of premenstrual flares, female predominance, and improvement during pregnancy suggest a hormonal/metabolic background. The reported positive effects of antiandrogen therapy supports a possible role of androgens. The predominant onset of the disease years after puberty may indicate a metabolic disorder. Obesity contributes significantly to HS pathogenesis; diabetes, dyslipidemia, the metabolic syndrome, and polycystic ovarian syndrome are among the commonest comorbidities. More studies are required to clarify a potential hormonal dysregulation in HS.

Abstract
Acne vulgaris is a common skin condition associated with multiple factors. Although mostly presenting alone, it can likewise present with features of hyperandrogenism and hormonal discrepancies. Of note, hormonal therapies are indicated in severe, resistant-to-treatment cases and in those with monthly flare-ups and when standard therapeutic options are inappropriate. This article serves as an update to hormonal pathogenesis of acne, discusses the basics of endocrinal evaluation for patients with suspected hormonal acne, and provides an overview of the current hormonal treatment options in women.

Abstract
The skin is an important extra-gonadal steroidogenic organ, capable of metabolizing various hormones from their precursors, as well as of synthesizing de novo a broad palette of sex steroids and glucocorticoids from cholesterol. In this manuscript, we review the major steroidogenic properties of human skin and we suggest steroidogenesis' impairment as a cardinal factor for various pathological conditions such as acne, rosacea, atopic dermatitis, and androgenic alopecia.

Abstract
OBJECTIVE Hirsutism results from hyperandrogenemia and/or exaggerated androgen responsiveness. Among various causes of hirsutism, some patients do not exhibit androgen excess which is called idiopathic hirsutism (IH). The pathogenesis of IH could not so far be clearly established. DESIGN To investigate the mRNA expression of aromatase enzyme and the other enzymes having functional roles in the steroidogenic pathway, in freshly obtained skin tissue from subumbilical skin and the arm of the patients with IH and healthy women. METHODS Twenty-one women with IH and 15 healthy women were included in the study. We aimed to determine mRNA expressions of genes associated with local androgen synthesis and metabolism (CYP11A1, STS, CYP19A1, SRD5A1, SRD5A2, HSD3B1, AR, COMT, ESR1, ESR2, HSD3B2, CYP17A1, SULT2A1, SULT1E1, HSD17B2, IL6, TGFB1, TNFA) from skin biopsy and blood samples of patients with IH and the data compared with healthy subjects. RESULTS Patients with IH exhibit significantly lower interleukin 6 (IL6) mRNA expression and higher steroid sulphatase (STS) and hydroxysteroid (17beta) dehydrogenase 2 (HSD17B2), gene mRNA expression, respectively, in the subumbilical region skin biopsies. Similarly, patients with IH exhibit significantly lower IL6 mRNA expression and higher STS and HSD17B2 gene mRNA expression, respectively, in the arm skin compared to healthy women's subumbilical region. CONCLUSIONS In both arm and subumbilical skin biopsy of patients with IH, we observed an up-regulation of HSD17B2 and STS, decreased IL6 mRNA expression, probably determining an increase in the local amount of active androgens, which could then be used as substrate for other androgen metabolic routes.

Synthesis of methoxycarbonylpyrazolylandrostene derivatives, and their potential inhibitory effect on androgen biosynthesis and cell proliferation. Steroids 2015; 98:143-52. [PMID: 25804762 DOI: 10.1016/j.steroids.2015.03.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2014] [Revised: 02/16/2015] [Accepted: 03/12/2015] [Indexed: 10/23/2022]
Abstract
The Claisen condensations of 3β-acetoxypregn-5-en-20-one (1) and 3β-acetoxypregna-5,16-diene (7) with dimethyl oxalate are known to lead to 3β-hydroxy-21-methoxalylpregn-5-en-20-one (2) and 3β-hydroxy-21-methoxalylpregna-5,16-dien-20-one (8), respectively. The reactions of 2 with p-substituted phenylhydrazines afford pyrazol-5-yl derivatives (5) as main, and 3-yl regioisomers (4) as minor products. The corresponding reactions of 16-ene analogue 8 afford only pyrazol-5-yl regioisomer 9. Oppenauer oxidation of the pyrazolyl compounds yields the corresponding Δ(4)-3-ketosteroids. We investigated the antiandrogenic effects of new methoxycarbonylpyrazolyl compounds through determination of their in vitro inhibition of the activities of rat testicular C17,20-lyase, Δ(5)-3β-hydroxysteroid dehydrogenase (Δ(5)-3β-HSD) and 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3). A Δ(5)-3β-hydroxy compound in the D-ring-saturated androst-5-ene series bearing an unsubstituted phenyl group on the pyrazolyl heterocycle (5a) proved to be a potent inhibitor of Δ(5)-3β-HSD. The 4-methoxyphenyl derivative (5e) and the 3-oxo counterpart (6a) of 5a also displayed substantial inhibition. The other tested compounds exerted only weak inhibitory action against the enzymes investigated. The newly synthetized compounds were evaluated in vitro by means of MTT assays for antiproliferative activity against Hela (cervical carcinoma), A431 (skin epidermoid carcinoma) and MCF7 (breast adenocarcinoma) cells. In all four groups (3β-hydroxy- and 3-ketosteroids with saturated or unsaturated ring D), the most potent analogs contain a 4-tolyl or 4-methoxyphenyl group. Compound 5d exhibited substantial antiproliferative action against the three cell lines investigated, whereas 9d inhibited the growth of Hela cells markedly. The most noteworthy inhibition was exerted by 6a against A431 cells.
