    [Maximal androgen deprivation with abiraterone acetate in hormone sensitive prostate cancer.]
    Arch Esp Urol 2018 03;71(3):267-275
    Servicio de Urología. Hospital Universitario 12 de Octubre. Madrid. España.
    Objectives: The treatment of metastatic prostate cancer has remained unchanged for more than 70 years, based on androgen deprivation therapy (ADT). In 2015, following the CHAARTED and STAMPEDE trials, it was established that the addition of 6 cycles of docetaxel to ADT was associated with significantly increased survival. In June 2017, the LATITUDE trial and the G arm of the STAMPEDE trial showed that the addition of Abiraterone with Prednisone (5 mg/day) to ADT was also associated with a significant increase in survival in metastatic patients.

    Contemporary approaches to the management of polycystic ovary syndrome.
    Ther Adv Endocrinol Metab 2018 Apr 7;9(4):123-134. Epub 2018 Feb 7.
    University Alma Mater Studiorum of Bologna, Via Santo Stefano 38, 40125 Bologna, Italy.
    Polycystic ovary syndrome (PCOS) is a common disorder in women in their reproductive years and is characterized by androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. It is also associated with several metabolic abnormalities, particularly insulin resistance and obesity, which play an important role in the pathophysiology of PCOS and, in particular, negatively influence ovarian function and fertility. This review article summarizes the available treatment for women with PCOS. Read More

    Ontogeny and reversal of brain circuit abnormalities in a preclinical model of PCOS.
    JCI Insight 2018 Apr 5;3(7). Epub 2018 Apr 5.
    Androgen excess is a hallmark of polycystic ovary syndrome (PCOS), a prevalent yet poorly understood endocrine disorder. Evidence from women and preclinical animal models suggests that elevated perinatal androgens can elicit PCOS onset in adulthood, implying androgen actions in both PCOS ontogeny and adult pathophysiology. Prenatally androgenized (PNA) mice exhibit a robust increase of progesterone-sensitive GABAergic inputs to gonadotropin-releasing hormone (GnRH) neurons implicated in the pathogenesis of PCOS.

    A Klinefelter boy with congenital adrenal hyperplasia: too much or too little androgens?
    Ital J Pediatr 2018 Apr 3;44(1):43. Epub 2018 Apr 3.
    Department of Pediatrics, Institute for Maternal and Child Health IRCCS, "Burlo Garofolo", Via dell' Istria 65/1, Trieste, Italy.
    Background: The simultaneous occurrence of Klinefelter Syndrome (KS) and Congenital Adrenal Hyperplasia (CAH) is an exceptional event: there are just three case reports (two children and a 51 years old man) describing males affected by both KS and 21OHD (21-hydroxylase deficiency) CAH, the first causing androgen deficiency, the latter leading to androgen excess.

    Case Report: We report the 4th case of association of KS and CAH in a young man with CAH with good androgen control and with normal secondary sex characteristics, whose Klinefelter syndrome was diagnosed because of reduced testicular volume. He was the first reported case of association of KS and CAH who started androgen replacement therapy in the pubertal age and whose pubertal development was described and followed up step by step.

    Polycystic ovary syndrome, androgen excess, and the risk of nonalcoholic fatty liver disease in women: A longitudinal study based on a United Kingdom primary care database.
    PLoS Med 2018 Mar 28;15(3):e1002542. Epub 2018 Mar 28.
    Institute of Applied Health Research, University of Birmingham, Birmingham, United Kingdom.
    Background: Androgen excess is a defining feature of polycystic ovary syndrome (PCOS), which affects 10% of women and represents a lifelong metabolic disorder, with increased risk of type 2 diabetes, hypertension, and cardiovascular events. Previous studies have suggested an increased risk of nonalcoholic fatty liver disease (NAFLD) in individuals with PCOS and implicated androgen excess as a potential driver.

    Methods And Findings: We carried out a retrospective longitudinal cohort study utilizing a large primary care database in the United Kingdom, evaluating NAFLD rates in 63,120 women with PCOS and 121,064 age-, body mass index (BMI)-, and location-matched control women registered from January 2000 to May 2016.

    Estrogen: The necessary evil for human health, and ways to tame it.
    Biomed Pharmacother 2018 Mar 21;102:403-411. Epub 2018 Mar 21.
    Department of Botany, Berhampur University, Berhampur, Odisha, 760007, India.
    Estrogen is a pivotal enzyme for survival and health in both genders, though their quantum, tropism, tissue-specific distribution, and receptor affinity varies with different phases of life. Converted from androgen via aromatase enzyme, this hormone is indispensable to glucose homeostasis, immune robustness, bone health, cardiovascular health, fertility, and neural functions. However, estrogen is at the center of almost all human pathologies as well-infectious, autoimmune, metabolic to degenerative. Read More

    Polycystic ovary syndrome: definition, aetiology, diagnosis and treatment.
    Nat Rev Endocrinol 2018 May 23;14(5):270-284. Epub 2018 Mar 23.
    Department of Endocrinology and Nutrition, Hospital Universitario Ramón y Cajal, Madrid, Spain.
    Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders in premenopausal women. Heterogeneous by nature, PCOS is defined by a combination of signs and symptoms of androgen excess and ovarian dysfunction in the absence of other specific diagnoses. The aetiology of this syndrome remains largely unknown, but mounting evidence suggests that PCOS might be a complex multigenic disorder with strong epigenetic and environmental influences, including diet and lifestyle factors.

    A Major Population of Functional KLRG1 ILC2s in Female Lungs Contributes to a Sex Bias in ILC2 Numbers.
    Immunohorizons 2018 Feb;2(2):74-86
    Arthritis and Clinical Immunology Program, Oklahoma Medical Research Foundation, Oklahoma City, OK 73104.
    Humans show significant sex differences in the incidence and severity of respiratory diseases, including asthma and virus infection. Sex hormones contribute to the female sex bias in type 2 inflammation associated with respiratory diseases, consistent with recent reports that female lungs harbor greater numbers of GATA-3-dependent group 2 innate lymphoid cells (ILC2s). In this study, we determined whether sex hormone levels govern sex differences in the numbers, phenotype, and function of ILC2s in the murine lung and bone marrow (BM). Read More

    Maternal androgen excess and obesity induce sexually dimorphic anxiety-like behavior in the offspring.
    FASEB J 2018 Mar 22:fj201701263RR. Epub 2018 Mar 22.
    Department of Physiology and Pharmacology, Karolinska Institutet, Stockholm, Sweden.
    Maternal polycystic ovary syndrome (PCOS), a condition associated with hyperandrogenism, is suggested to increase anxiety-like behavior in the offspring. Because PCOS is closely linked to obesity, we investigated the impact of an adverse hormonal or metabolic maternal environment and offspring obesity on anxiety in the offspring. The obese PCOS phenotype was induced by chronic high-fat-high-sucrose (HFHS) consumption together with prenatal dihydrotestosterone exposure in mouse dams. Read More

    Dehydroepiandrosterone-induced activation of mTORC1 and inhibition of autophagy contribute to skeletal muscle insulin resistance in a mouse model of polycystic ovary syndrome.

    Congenital adrenal hyperplasia: clinical symptoms and diagnostic methods.
    Acta Biochim Pol 2018 15;65(1):25-33. Epub 2018 Mar 15.
    Department of Pediatrics, Pediatric Endocrinology and Diabetes, Medical Faculty, University of Rzeszów, Rzeszów, Poland.
    The aim of this paper is a straightforward presentation of the steroidogenesis process and the most common type of congenital adrenal hyperplasia (CAH) - 21-hydroxylase deficiency - as well as the analytical diagnostic methods that are used to recognize this disease. CAH is a family of common autosomal recessive disorders characterized by impaired adrenal cortisol biosynthesis with associated androgen excess due to a deficiency of one or more enzymes in the steroidogenesis process within the adrenal cortex. The most common and prototypical example of the CAH disorders group (90-95%) is caused by 21-hydroxylase deficiency. Read More

    Long-term urinary symptoms in adolescent and adult women with congenital adrenal hyperplasia.
    J Pediatr Urol 2018 Feb 7. Epub 2018 Feb 7.
    Gynaecology Department, Royal Children's Hospital, Melbourne, Australia; Department of Paediatrics, University of Melbourne, Melbourne, Australia. Electronic address:
    Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition resulting in excess androgen production. Females are typically born with ambiguous genitalia and often undergo feminising genitoplasty in infancy or childhood. Recently, there has been considerable international debate as to whether distressing urinary symptoms in CAH patients are truly present and, if so, whether these urinary problems are a consequence of the feminising genitoplasty.

    An ovarian Leydig cell tumor of ultrasound negative in a postmenopausal woman with hirsutism and hyperandrogenism: A case report.
    Medicine (Baltimore) 2018 Mar;97(10):e0093
    Department of Endocrinology, the First Affiliated Hospital, College of Medicine, Zhejiang University.
    Rationale: The incidence of severe hyperandrogenism associated with masculinity in women is very low. While rare and difficult to diagnose, androgen secreting tumors should be suspected in women with hyperandrogenism and hirsutism, especially in the postmenopausal population. Herein we present one case of ovarian Leydig cell tumor (LCT) with markedly elevated serum testosterone levels and frank hirsutism. Read More

    Antiandrogen Treatment Ameliorates Reproductive and Metabolic Phenotypes in the Letrozole-Induced Mouse Model of PCOS.
    Endocrinology 2018 Apr;159(4):1734-1747
    Department of Reproductive Medicine, Center for Reproductive Science and Medicine, University of California, San Diego, La Jolla, California.
    Polycystic ovary syndrome (PCOS), the most common endocrinopathy in women of reproductive age, is characterized by hyperandrogenism, anovulation, and polycystic ovaries. Although its etiology is unknown, excess androgens are thought to be a critical factor driving the pathology of PCOS. We previously demonstrated that continuous exposure to the aromatase inhibitor letrozole (LET) in mice produces many hallmarks of PCOS, including elevated testosterone (T) and luteinizing hormone, anovulation, and obesity.

    MANAGEMENT OF ENDOCRINE DISEASE Hyperandrogenic states in women: pitfalls in laboratory diagnosis.
    Eur J Endocrinol 2018 Apr 16;178(4):R141-R154. Epub 2018 Feb 16.
    Laboratoire d'Hormonologied'Endocrinologie Moléculaire et des Maladies Rares, Groupement Hospitalier Est, Hospices Civils de Lyon, Bron, France.
    Measuring total testosterone level is the first-line approach in assessing androgen excess in women. The main pitfalls in measuring testosterone relate to its low concentration and to the structural similarity between circulating androgens and testosterone, requiring accurate techniques with high specificity and sensitivity. These goals can be achieved by immunoassay using a specific anti-testosterone monoclonal antibody, ideally after an extraction step. Read More

    Medicine and Surgery, University of Milano-Bicocca, Milano, Italy.
    Metabolic syndrome (MetS) is highly correlated with cardiovascular diseases. Although an excess of body fat is a determinant factor for MetS development, a reduced level of testosterone plays a fundamental role in its regulation. Low testosterone level is highly related to insulin resistance, visceral obesity and MetS. Read More

    Insulin signaling displayed a differential tissue-specific response to low-dose dihydrotestosterone in female mice.
    Am J Physiol Endocrinol Metab 2018 Apr 19;314(4):E353-E365. Epub 2017 Dec 19.
    Division of Pediatric Endocrinology, Johns Hopkins School of Medicine , Baltimore, Maryland.
    Hyperandrogenemia and hyperinsulinemia are believed to play prominent roles in polycystic ovarian syndrome (PCOS). We explored the effects of low-dose dihydrotestosterone (DHT), a model of PCOS, on insulin signaling in metabolic and reproductive tissues in a female mouse model. Insulin resistance in the energy storage tissues is associated with type 2 diabetes. Read More

    Causes, Patterns, and Severity of Androgen Excess in 1205 Consecutively Recruited Women.
    J Clin Endocrinol Metab 2018 Mar;103(3):1214-1223
    Institute of Metabolism and Systems Research, University of Birmingham, Birmingham, United Kingdom.
    Context: Androgen excess in women is predominantly due to underlying polycystic ovary syndrome (PCOS). However, there is a lack of clarity regarding patterns and severity of androgen excess that should be considered predictive of non-PCOS pathology.

    Objective: We examined the diagnostic utility of simultaneous measurement of serum dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4), and testosterone (T) to delineate biochemical signatures and cutoffs predictive of non-PCOS disorders in women with androgen excess. Read More

    Children with premature pubarche: is an alterated neonatal 17-Ohp screening test a predictive factor?
    Ital J Pediatr 2018 Jan 16;44(1):10. Epub 2018 Jan 16.
    Pediatric Division, Department of Pediatrics, University Hospital of Verona, Verona, Italy.
    Background: Neonatal screening for 21 hydroxylase deficiency is designed to detect classical form of congenital adrenal hyperplasia (CAH). It is still unclear whether newborns who result false positives at neonatal screening might later develop signs of androgen excess. The aim of this study is to verify whether a slightly elevated 17-OHP at newborn screening is a predictive factor for premature pubarche. Read More

    Mitotane treatment in patients with metastatic testicular Leydig cell tumor associated with severe androgen excess.
    Eur J Endocrinol 2018 Mar 12;178(3):K21-K27. Epub 2018 Jan 12.
    Institute of Metabolism and Systems ResearchUniversity of Birmingham, Birmingham, UK
    Mitotane (o,p'DDD) is established in the adjuvant and advanced-stage treatment of adrenocortical carcinoma and counteracts both tumor growth and tumor-related steroid production. Both the adrenal glands and the gonads are steroidogenically active organs and share a common embryogenic origin. Here, we describe the effects of mitotane in two patients with metastatic Leydig cell tumor (LCT) of the testes and associated severe androgen excess (serum testosterone 93 and 88 nmol/L, respectively; male reference range 7-27 nmol/L). Read More

    Premature Adrenarche.
    Pediatr Ann 2018 Jan;47(1):e7-e11
    Adrenarche is when a child's adrenal cortex starts to secrete adrenal androgen precursors. Dehydroepiandrosterone (DHEA) is the most abundant product of the adrenal cortex, and is a weak androgen agonist thought to be responsible for the clinical signs of pubarche by conversion to more potent androgens, testosterone, and dihydrotestosterone. DHEA's extra-adrenal sulfation product, dehydroepiandrosterone sulfate, is a stable marker for adrenal androgenic activity. Read More

    Anogenital distance in newborn daughters of women with polycystic ovary syndrome indicates fetal testosterone exposure.
    J Dev Orig Health Dis 2018 Jan 9:1-8. Epub 2018 Jan 9.
    9Department of Preventive Medicine,Icahn School of Medicine at Mount Sinai,New York,NY,USA.
    Polycystic ovary syndrome (PCOS) affects ~7% of reproductive age women. Although its etiology is unknown, in animals, excess prenatal testosterone (T) exposure induces PCOS-like phenotypes. While measuring fetal T in humans is infeasible, demonstrating in utero androgen exposure using a reliable newborn biomarker, anogenital distance (AGD), would provide evidence for a fetal origin of PCOS and potentially identify girls at risk. Read More

    Suspected ontogeny of a recently described hypo-androgenic PCOS-like phenotype with advancing age.
    Endocrine 2018 Mar 6;59(3):661-676. Epub 2018 Jan 6.
    The Center for Human Reproduction, New York, NY, 10021, USA.
    Background: A recent report described a new PCOS-like phenotype in lean older infertile women, and was characterized by high age-specific anti-Müllerian hormone (AMH) but hypo- rather than the expected hyper-androgenism. The hypo-androgenism was, furthermore, characterized of, likely, adrenal origin and autoimmune etiology.

    Patients And Methods: We extracted data on 708 consecutive infertility patients, and separated them into three age-strata, <35, 36-42, and >42 years. Read More

    Combined oral contraceptives and/or antiandrogens versus insulin sensitizers for polycystic ovary syndrome: a systematic review and meta-analysis.
    Hum Reprod Update 2017 Dec 27. Epub 2017 Dec 27.
    Department of Endocrinology & Metabolism, Hospital Universitario Ramón y Cajal & Universidad de Alcalá, E-28034 Madrid, Spain.
    Background: Androgen excess is a key pathogenetic mechanism in polycystic ovary syndrome (PCOS), although hyperinsulinism also contributes to androgen secretion. Therapeutic approaches for adult patients not seeking fertility include combined oral contraceptives (COC), antiandrogens (AA) and/or insulin sensitizers, although these practices are supported by limited high-quality evidence.

    Objective And Rationale: We aimed to assess the efficacy and safety of these common treatments for PCOS by conducting a meta-analysis of RCTs with the following review questions: Which is the more appropriate therapeutic approach for hyperandrogenic symptoms, hyperandrogenemia, and ovulatory dysfunction in adult women with PCOS not seeking fertility; What is the impact on classic cardiometabolic risk factors of the more common treatments used in those women; Does the combination of the antiandrogenic therapy plus metformin have any impact on efficacy or cardiometabolic profile?

    Search Methods: We searched PubMed and EMBASE for articles published up to 16 September 2017. Read More

    Management of adult patients with classic congenital adrenal hyperplasia (CAH) is challenging and often complicated by obesity, metabolic syndrome, and adverse cardiovascular risk. Alterations in weight can influence cortisol kinetics. A 19-year-old woman with classic CAH and morbid obesity experienced persistent elevations of androgen levels while receiving oral glucocorticoid therapy. Read More

    Developmental Programming: Impact of Prenatal Testosterone Excess on Steroidal Machinery and Cell Differentiation Markers in Visceral Adipocytes of Female Sheep.

    Prenatal testosterone (T)-treated female sheep manifest reduced adipocyte size and peripheral insulin resistance. The small adipocyte phenotype may reflect defects in adipogenesis and its steroidal machinery. To test whether prenatal T treatment from gestational days 30 to 90 alters the visceral adipose tissue (VAT) steroidal machinery and reduces adipocyte differentiation, we examined expression of the steroidogenic enzymes, steroid receptors, and adipocyte differentiation markers at fetal day 90 and postnatal ages 10 and 21 months.

    Do Different Diagnostic Criteria Impact Polycystic Ovary Syndrome Diagnosis for Adolescents?
    J Pediatr Adolesc Gynecol 2017 Dec 9. Epub 2017 Dec 9.
    Division of Adolescent Medicine, Department of Pediatrics, Hacettepe University Faculty of Medicine, Ankara, Turkey.
    Study Objective: Although early diagnosis of polycystic ovary syndrome (PCOS) in adolescents might allow for earlier treatment and prevention of chronic disorders, incorrect or premature diagnosis carries risks of unnecessary treatment and psychological distress. There is no consensus concerning which diagnostic criteria to use for adolescents and current criteria vary. The objective of this study was to determine whether using different diagnostic criteria will affect PCOS diagnosis in adolescents. Read More

    The Role of Androgen Excess in Metabolic Dysfunction in Women : Androgen Excess and Female Metabolic Dysfunction.

    Polycystic ovary syndrome (PCOS) is characterized by the association of androgen excess with chronic oligoovulation and/or polycystic ovarian morphology, yet metabolic disorders and classic and nonclassic cardiovascular risk factors cluster in these women from very early in life. This chapter focuses on the mechanisms underlying the association of PCOS with metabolic dysfunction, focusing on the role of androgen excess on the development of visceral adiposity and adipose tissue dysfunction.

    The in-depth characterization of sex differences relevant to human physiology requires the judicious use of a variety of animal models and human clinical data. Nonhuman primates (NHPs) represent an important experimental system that bridges rodent studies and clinical investigations. NHP studies have been especially useful in understanding the role of sex hormones in development and metabolism and also allow the elucidation of the effects of pertinent dietary influences on physiology pertinent to disease states such as obesity and diabetes.

    Molecular Modifiers of Hormone Receptor Action: Decreased Androgen Receptor Expression in Mismatch Repair Deficient Endometrial Endometrioid Adenocarcinoma.
    Int J Gynecol Pathol 2017 Nov 28. Epub 2017 Nov 28.
    Department of Pathology, The University of Texas M.D. Anderson Cancer Center, Houston, Texas.
    Endometrial endometrioid carcinoma is related to estrogen excess and expression of estrogen and progesterone receptors. Epidemiological evidence suggests that exposure to elevated androgens, as in polycystic ovarian syndrome, increases the risk of endometrial cancer. Factors impacting androgen receptor (AR) expression are not well studied. Read More
