Sexuality and fertility in women with Addison's disease

Androgen Inhibition of Reproductive Neuroendocrine Function in Females and Transgender Males

Ovarian function is controlled by pituitary secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH), which in turn are governed by gonadotropin releasing hormone (GnRH) secreted from the brain. A fundamental principle of reproductive axis regulation is negative feedback signaling by gonadal sex steroids back to the brain to fine-tune GnRH and gonadotropin secretion. Endogenous negative feedback effects can be mimicked by exogenous steroid treatments, including androgens, in both sexes. Indeed, a growing number of clinical and animal studies indicate that high levels of exogenous androgens, in the typically male physiological range, can inhibit LH secretion in females, as occurs in males. However, the mechanisms by which male-level androgens inhibit GnRH and LH secretion still remain poorly understood, and this knowledge gap is particularly pronounced in transgender men (individuals designated female at birth but identifying as male). Indeed, many transgender men take long-term gender-affirming hormone therapy that mimics male-level testosterone levels. The impact of such gender-affirming testosterone on the reproductive axis, both at the ovarian and neuroendocrine level, is a long-understudied area that still requires further investigation. Importantly, the few concepts of androgen actions in females mostly come from studies of polycystic ovary syndrome, which does not recapitulate a similar androgen milieu or a pathophysiology of inhibited LH secretion as occurs in testosterone-treated transgender men. This review summarizes clinical evidence indicating that exogenous androgens can impair neuroendocrine reproductive function in both female individuals and transgender men and highlights emerging experimental data supporting this in recently developed transgender rodent models.

Fertility issues in hypopituitarism

Women with hypopituitarism have lower fertility rates and worse pregnancy outcomes than women with normal pituitary function. These disparities exist despite the use of assisted reproductive technologies and hormone replacement. In women with hypogonadotropic hypogonadism, administration of exogenous gonadotropins can be used to successfully induce ovulation. Growth hormone replacement in the setting of growth hormone deficiency has been suggested to potentiate reproductive function, but its routine use in hypopituitary women remains unclear and warrants further study. In this review, we will discuss the clinical approach to fertility in a woman with hypopituitarism.

Endocrine factors associated with infertility in women: an updated review

INTRODUCTION

Infertility is defined as the inability to conceive after unprotected sexual intercourse for at least 12 consecutive months. Our objective is to present an updated narrative review on the endocrine causes of infertility in women.

AREAS COVERED

A comprehensive review was conducted using Scielo, Scopus, and EMBASE databases, comprising 245 articles. The pathophysiology of infertility in women was described, including endocrinopathies such as hypothalamic amenorrhea, hyperprolactinemia, polycystic ovary syndrome, primary ovarian insufficiency, obesity, thyroid dysfunction, and adrenal disorders. The diagnostic approach was outlined, emphasizing the necessity of hormonal studies and ovarian response assessments. Additionally, the treatment plan was presented, commencing with non-pharmacological interventions, encompassing the adoption of a Mediterranean diet, vitamin supplementation, moderate exercise, and maintaining a healthy weight. Subsequently, pharmacological treatment was discussed, focusing on the management of associated endocrine disorders and ovulatory dysfunction.

EXPERT OPINION

This comprehensive review highlights the impact of endocrine disorders on fertility in women, providing diagnostic and therapeutic algorithms. Despite remaining knowledge gaps that hinder more effective treatments, ongoing research and advancements show promise for improved fertility success rates within the next five years. Enhanced comprehension of the pathophysiology behind endocrine causes and the progress in genetic research will facilitate the delivery of personalized treatments, thus enhancing fertility rates.

AOP key event relationship report: Linking decreased androgen receptor activation with decreased granulosa cell proliferation of gonadotropin-independent follicles

We recently proposed to formally recognize Key Event Relationships (KERs) as building blocks of Adverse Outcome Pathways (AOPs) that can be independently developed and peer-reviewed. Here, we follow this approach and provide an independent KER from AOP345, which describes androgen receptor (AR) antagonism leading to decreased female fertility. This KER connects AR antagonism to reduced granulosa cell proliferation of gonadotropin-independent follicles (KER2273). We have developed both the KER and the two adjacent Key Events (KEs). A systematic approach was used to ensure that all relevant supporting evidence for KER2273 was retrieved. Supporting evidence for the KER highlights the importance of AR action during the early stages of follicular development. Both biological plausibility and empirical evidence are presented, with the latter also assessed for quality. We believe that tackling isolated KERs instead of whole AOPs will accelerate the AOP development. Faster AOP development will lead to the development of simple test methods that will aid screening of chemicals, endocrine disruptor identification, risk assessment, and subsequent regulation.

Adrenal insufficiency and pregnancy

INTRODUCTION

Adrenal insufficiency is a disorder characterized by the failure of adrenocortical function because of distorted function of hypothalamic-pituitary- adrenal (HPA) axis. Pregnancy is a state of a physiological glucocorticoid excess as the HPA axis is functioning at a higher level.

PURPOSE OF REVIEW

The aim of the present review was to shed light on current evidence of adrenal insufficiency management during pregnancy, along with maternal and neonatal outcomes.

RECENT FINDINGS

A recent multicenter study under the auspices of the European Network for the Study of Adrenal Tumours (ENSAT) presented real-life data of pregnant women with adrenal insufficiency documenting an increased use of hydrocortisone (or mineralocorticoids when needed according to the level of disorder) replacement treatment, increased rates of caesarean section, preterm delivery and adrenal crises along with peripartum and postpartum complications but no maternal or neonatal fatality. These data were in agreement with those obtained from previously published studies.

CONCLUSION

The limited published evidence is in line with the present guidelines as real-life data did not document any increased fatality among pregnant women or newborns. Prospective data with prolonged follow-up are needed to shed more light on appropriate dose adjustments to avoid the risks of under-replacement or over-replacement of glucocorticoid and/or mineralocorticoid drugs and their sequelae.

SUMMARY

A recent multicenter study by ENSAT presented real-life data of pregnant women with adrenal insufficiency documenting an increased use of hydrocortisone as replacement treatment during pregnancy, along with an increased rate of caesarean section and preterm delivery, adrenal crises, peripartum and postpartum complications but no maternal or neonatal fatality. These data are in agreement with those of a previously published study and also confirm the statements made by the recent guidelines. Prospective data are needed aiming to develop precise therapeutic protocols during each trimester of pregnancy according to the different causes of adrenal insufficiency.

Sexual dysfunctions in Sheehan's syndrome

BACKGROUND

Sheehan's syndrome (SS) is not an uncommon cause of hypopituitarism in developing countries. Lack of sex-steroids both from ovaries and adrenals could lead to sexual dysfunction in SS. Sexual function is a neglected aspect of health in women in developing countries, though it contributes greatly towards quality of life and feeling of well being. Objective documentation of sexual function in SS is limited.

MATERIALS AND METHODS

Thirty two subjects with SS on conventional therapy (except Growth Hormone) were evaluated. SS was diagnosed as per standard criteria. Sexual function was assessed by validated questionnaires using Female Sexual Function Index (FSFI). Thirty healthy women of similar age range and socio-economic background were included as comparators.

RESULTS

Mean age (±SD) of study population and healthy controls were 39.9 (±8.6) and 38.2 (±6.8) years respectively. Median (IQR) interval between inciting event and diagnosis of SS was 8.3 (5.2-13.5) years. Thirty subjects were active sexually. Twenty eight (93%) had sexual dysfunction i.e. FSFI score ≤ 26.55. Median total FSFI scores in SS and controls were 20.8 and 29.05 respectively (p=0.001). There was statistically significant difference for individual parameter of sexual function i.e. desire, arousal, lubrication, orgasm and satisfaction between SS and controls. However pain during intercourse was not different. FSFI score in SS was not correlated with any of the endocrine parameters or duration of the disease since diagnosis.

CONCLUSION

Sexual dysfunction is very common affecting more than 90% of subjects with SS.

Female Sexual Dysfunction in Primary Adrenal Insufficiency

Purpose. No data are currently available on female sexual dysfunction (FSD) in primary adrenal insufficiency (PAI) and the possible impact of replacement therapy. The aim of this study was to evaluate the prevalence of FSD and sexual distress (SD), and to evaluate the possible impact of replacement therapy on sexuality in women with PAI. Methods. Female Sexual Function Index-6 (FSFI-6) and Sexual Distress Scale (SDS) questionnaires were administered to 22 women with PAI and 23 healthy women matched for age as controls. Results. The prevalence of sexual symptoms measured by FSFI-6 (total score < 19) was significantly higher in women with PAI (15/22; 68.2%) compared to the controls (2/23; 8.7%; p = 0.001). Regarding the questionnaire items, significantly different scores were found for desire (p < 0.001), arousal (p = 0.0006), lubrication (p = 0.046) and overall sexual satisfaction (p < 0.0001) in women with PAI compared to the controls. The rate of FSD (FSFI < 19 with SDS >15) was 60% in patients with PAI. A significant inverse correlation was found between FSFI-6 total scores and SD (r = −0.65; p = 0.0011), while a significant direct correlation was found between FSFI-6 total scores and serum cortisol levels (r = 0.55; p = 0.035). Conclusions. A higher prevalence of FSD was found in women affected by PAI compared to healthy women. Desire seems to be the most impaired aspect of sexual function. Moreover, sexual dysfunction in this population seems to be related to sexual distress and cortisol levels.

Primary Ovarian Insufficiency in Women With Addison's Disease

CONTEXT

Primary ovarian insufficiency (POI) is defined by menopause before 40 years of age. POI prevalence is higher among women with autoimmune Addison's disease (AAD) than in the general population, but their clinical characteristics are insufficiently studied.

OBJECTIVE

To assess the prevalence of POI in a large cohort of women with AAD and describe clinical, immunological, and genetic characteristics.

METHODS

An observational population-based cohort study of the Norwegian National Addison Registry. The Norwegian Prescription Database was used to assess prescription of menopausal hormone replacement therapy (HRT). A total of 461 women with AAD were studied. The primary outcome measure was prevalence of POI. Secondary outcomes were clinical characteristics, autoantibodies, and genome-wide single nucleotide polymorphism variation.

RESULTS

The prevalence of POI was 10.2% (47/461) and one-third developed POI before 30 years of age. POI preceded or coincided with AAD diagnosis in more than half of the women. The prevalence of concomitant autoimmune diseases was 72%, and AAD women with POI had more autoantibodies than AAD women without (≥2 autoantibodies in 78% vs 25%). Autoantibodies against side-chain cleavage enzyme (SCC) had the highest accuracy with a negative predictive value for POI of 96%. HRT use was high compared to the age adjusted normal population (11.3 % vs 0.7%).

CONCLUSION

One in 10 women with AAD have POI. Autoantibodies against SCC are the most specific marker for autoimmune POI. We recommend testing women with AAD <40 years with menstrual disturbances or fertility concerns for autoantibodies against SCC.

Portable Chemiluminescence-Based Lateral Flow Assay Platform for the Detection of Cortisol in Human Serum

In this study, we developed the portable chemiluminescence (CL)-based lateral flow assay (LFA) platform for the detection of cortisol in human serum. Cortisol is well-known as a stress hormone due to its high relevancy for human mental and physical health, such as hypertension or depression. To date, a number of optical devices have provided the sensitive determination of levels of analytes. However, this modality type still requires costly optical modules. The developed CL platform is simply composed of two detection modules along with a loading part for the LFA strip. The LFA membrane contains gold nanoparticle probes conjugated with antibodies against cortisol and horseradish peroxidase (HRP), which can also efficiently increase the luminescent signal by providing many areas for anti-cortisol antibody and HRP. The measured voltage signals coming from the photodiode in a CL reader were compared with a standard microplate reader for the evaluation of accuracy. The linear range observed for cortisol was measured to be 0.78–12.5 μg/dL (R² = 0.99) with a limit of detection (LOD) of 0.342 μg/dL. In addition, the CL-LFA reader showed a high correlation (R² = 0.96) with the standard cortisol console (COBAS 8000, Roche), suggesting that our developed CL-based LFA platform can be usable in situ.

Adrenal insufficiency

Adrenal insufficiency (AI) is a condition characterized by an absolute or relative deficiency of adrenal cortisol production. Primary AI (PAI) is rare and is caused by direct adrenal failure. Secondary AI (SAI) is more frequent and is caused by diseases affecting the pituitary, whereas in tertiary AI (TAI), the hypothalamus is affected. The most prevalent form is TAI owing to exogenous glucocorticoid use. Symptoms of AI are non-specific, often overlooked or misdiagnosed, and are related to the lack of cortisol, adrenal androgen precursors and aldosterone (especially in PAI). Diagnosis is based on measurement of the adrenal corticosteroid hormones, their regulatory peptide hormones and stimulation tests. The goal of therapy is to establish a hormone replacement regimen that closely mimics the physiological diurnal cortisol secretion pattern, tailored to the patient's daily needs. This Primer provides insights into the epidemiology, mechanisms and management of AI during pregnancy as well as challenges of long-term management. In addition, the importance of identifying life-threatening adrenal emergencies (acute AI and adrenal crisis) is highlighted and strategies for prevention, which include patient education, glucocorticoid emergency cards and injection kits, are described.

Fertility and pregnancy in women with primary adrenal insufficiency

Primary adrenal insufficiency (PAI) occurs in ~1/5000-1/7000 individuals and is in most cases caused by autoimmune Addison's disease (AAD). Around 10-20% of women with AAD develop premature ovarian insufficiency (POI) before the age of 40 years. 21-Hydroxylase autoantibodies (21OHAb) are the best single immune marker to classify AAD among PAI patients and autoimmune POI in hypergonadotropic hypogonadic women. In AAD, detection of steroid-cell autoantibodies (StCA) predicts future development of POI. AAD-related autoimmune POI is characterized by a selective destruction of theca cells with preservation of primary follicles and granulosa cells of secondary and tertiary follicles. Women with AAD show reduced fertility and parity. Patients with well-managed disease are generally expected to have uneventful pregnancies with favorable outcome, but increased risk of maternal and neonatal complications has been reported. Hence, AAD pregnant women must be carefully monitored by skilled staff which is familiar with the disorder and specific attention must be given to the substitutive therapy.

Autoimmune Addison's disease

Primary adrenal insufficiency (PAI) occurs in 1/5000-1/7000 individuals in the general population. Autoimmune Addison's disease (AAD) is the major cause of PAI and is a major component of autoimmune polyendocrine syndrome type 1 (APS1) and type 2 (APS2). Presence of 21-hydroxylase autoantibodies (21OHAb) identifies subjects with ongoing clinical or pre-clinical adrenal autoimmunity. AAD requires life-long substitutive therapy with two-three daily doses of hydrocortisone (HC) (15-25 mg/day) or one daily dose of dual-release HC and with fludrocortisone (0.5-2.0 mg/day). The lowest possible HC dose must be identified according to clinical and biochemical parameters to minimize long-term complications that include osteoporosis and cardiovascular and metabolic alterations. Women with AAD have lower fertility and parity as compared to age-matched healthy controls. Patients must be educated to double-triple HC dose in the case of fever or infections and to switch to parenteral HC in the case of vomiting, diarrhoea or acute hypotension.

Epidemiology, pathogenesis, and diagnosis of Addison's disease in adults

BACKGROUND

Addison's disease (AD) is a rare disorder and among adult population in developed countries is most commonly caused by autoimmunity. In contrast, in children genetic causes are responsible for AD in the majority of patients.

PURPOSE

This review describes epidemiology, pathogenesis, genetics, natural history, clinical manifestations, immunological markers and diagnostic strategies in patients with AD. Standard care treatments including the management of patients during pregnancy and adrenal crises consistent with the recent consensus statement of the European Consortium and the Endocrine Society Clinical Practice Guideline are described. In addition, emerging therapies designed to improve the quality of life and new strategies to modify the natural history of autoimmune AD are discussed.

CONCLUSIONS

Progress in optimizing replacement therapy for patients with AD has allowed the patients to lead a normal life. However, continuous education of patients and health care professionals of ever-present danger of adrenal crisis is essential to save lives of patients with AD.

Feedback on LH in Testosterone-Clamped Men Depends on the Mode of Testosterone Administration and Body Composition

Context

Quantitative studies of the short-term feedback of testosterone (T) on luteinizing hormone (LH) secretion in healthy men are relatively rare. Such studies require the shutting down of endogenous T secretion and the imposition of experimentally controlled IV T addback.

Objective

To evaluate whether pulsatile and continuous T delivery confers equivalent negative feedback on LH secretion.

Design

This was a placebo-controlled, blinded, and prospectively randomized crossover study comprising 16 healthy men [age range 23 to 54 years and a body mass index (BMI) between 22.3 and 34.2 kg/m²]. Subjects received ketoconazole to block endogenous T secretion and received continuous or 90-minute pulses of IV T addback.

Setting

The study was performed in a Clinical Translational Research Unit.

Interventions

Subjects underwent 14 hours of blood sampling at 10-minute intervals, with a bolus IV injection of 33 ng/kg gonadotropin-releasing hormone (GnRH).

Main Outcome Measures

Log-transformed LH and T concentration ratios before and after GnRH administration.

Results

Despite higher T concentrations during pulsatile T feedback, LH concentrations and secretion rates, whether driven by endogenous or exogenous GnRH, were similar to those during continuous T infusion, indicating diminished pulsatile T feedback. Feedback correlated negatively with BMI. Under controlled T feedback, basal but not pulsatile LH secretion correlated negatively with CT-estimated visceral fat mass.

Conclusion

Feedback by pulsatile T delivery has diminished inhibitory strength compared with continuous infusion. Feedback is negatively correlated with BMI.

Treatment of Addison's disease during pregnancy

Addison’s disease, or primary adrenocortical insufficiency, is a long-term, potentially severe, rare endocrine disorder. In pregnancy, it is even rarer. We report the case of a 30-year-old pregnant patient with Addison’s disease, referred to Obstetrics-Endocrinology specialty consult at 14 weeks gestation. She had been to the emergency department of her local hospital various times during the first trimester presenting with a clinical scenario suggestive of glucocorticoid under-replacement (nausea, persistent vomiting and hypotension), but this was interpreted as normal pregnancy symptoms. Hydrocortisone dose was adjusted, and the patient maintained regular follow-up. No complications were reported for the remainder of gestation and delivery. Pregnant patients with Addison’s disease should be monitored during gestation and in the peripartum period by multidisciplinary teams. Adjustments in glucocorticoid and mineralocorticoid replacement therapy are often necessary, and monitoring should be based mainly on clinical findings, which becomes increasingly difficult during pregnancy. Patient education and specialized monitoring are key to avoiding complications from under- or over-replacement therapy in this period.

MANAGEMENT OF ENDOCRINE DISEASE: Fertility, pregnancy and lactation in women with adrenal insufficiency

With the introduction of hormonal substitution therapy in the 1950s, adrenal insufficiency (AI) has been turned into a manageable disease in pregnant women. In fact, in the light of glucocorticoid replacement therapy and improved obstetric care, it is realistic to expect good maternal and fetal outcomes in patients with AI. However, there are still a number of challenges such as establishing the diagnosis of AI in pregnant women and optimizing the treatment of AI and related comorbidities prior to as well as during pregnancy. Clinical and biochemical diagnoses of a new-onset AI may be challenging because of overlapping symptoms of normal pregnancy as well as pregnancy-induced changes in cortisol values. Physiological changes occurring during pregnancy should be taken into account while adjusting the substitution therapy. The high proportion of reported adrenal crisis in pregnant women with AI highlights persistent problems in this particular clinical situation. Due to the rarity of the disease, there is no prospective data-guiding management of pregnancy in patients with known AI. The aim of this review is to summarize the maternal and fetal outcomes based on recently published case reports in patients with AI and to suggest a practical approach to diagnose and manage AI in pregnancy.

Ovulation, a sign of health

The concept of the ovarian continuum can be understood as a process that occurs during a woman's lifetime and begins during intrauterine life with fertilization. Women start their reproductive years with approximately five hundred thousand follicles containing oocytes, of which only around five hundred will be released during ovulation. Ovulation has been recognized as an event linked with reproduction; however, recent evidence supports the role of ovulation as a sign of health. The use of biomarkers that help women recognize ovulation enables them to identify their health status. This knowledge helps medical healthcare providers in the prevention, diagnosis, and treatment of different pathologies related with endocrine disorders, gynecological abnormalities, autoimmune, genetic, and neoplastic diseases, as well as pregnancy-related issues. The knowledge of the ovarian continuum and the use of biomarkers to recognize ovulation should be considered a powerful tool for women and medical professionals.

Summary

The ovarian continuum is a process that occurs during a woman's lifetime. It begins during intrauterine life with fertilization and ends with menopause. This process can be greatly affected by different conditions such as changes in hormonal levels and illnesses. Therefore, understanding and promoting the knowledge and use of biomarkers of ovulation in women is a key aspect to consider when evaluating their health status. The knowledge and education about the ovarian continuum should be taken into account as a powerful tool for women and medical professionals.

Glucocorticoids and Reproduction: Traffic Control on the Road to Reproduction

Glucocorticoids are steroid hormones that regulate diverse cellular functions and are essential to facilitate normal physiology. However, stress-induced levels of glucocorticoids result in several pathologies including profound reproductive dysfunction. Compelling new evidence indicates that glucocorticoids are crucial to the establishment and maintenance of reproductive function. The fertility-promoting or -inhibiting activity of glucocorticoids depends on timing, dose, and glucocorticoid responsiveness within a given tissue, which is mediated by the glucocorticoid receptor (GR). The GR gene and protein are subject to cellular processing, contributing to signaling diversity and providing a mechanism by which both physiological and stress-induced levels of glucocorticoids function in a cell-specific manner. Understanding how glucocorticoids regulate fertility and infertility may lead to novel approaches to the regulation of reproductive function.

Update on adrenal insufficiency: diagnosis and management in pregnancy

PURPOSE OF REVIEW

Adrenal insufficiency in pregnancy, although relatively rare, has significant clinical implications on both maternal and fetal outcomes. Hypothalamo-pituitary-adrenal axis dynamics and physiological changes are complex, thus diagnosis and management of adrenal insufficiency in pregnancy remain challenging.

RECENT FINDINGS

Studies consistently demonstrate a rise in total serum cortisol with pregnancy, but less data are available on free cortisol levels. Salivary cortisol values have been measured in normal pregnancy and in a few studies using healthy nonpregnant women controls. Although this adds to our current knowledge of hypothalamo-pituitary-adrenal axis changes in pregnancy, clear-cut cortisol reference ranges are yet to be established. Serum cortisol and the cosyntropin stimulation test (albeit with higher peak cortisol thresholds) are currently the diagnostic tests of choice. Hydrocortisone is the preferred glucocorticoid replacement in pregnancy as it is inactivated by placental 11-β-hydroxysteroid dehydrogenase 2; dose titration may be required, but should be individualized depending on clinical course and mode of delivery.

SUMMARY

Further studies on the long-term effects of maternal glucocorticoid regimens on the fetus and potential modulators of fetal glucocorticoid sensitivity and placental 11-β-hydroxysteroid dehydrogenase 2 are needed and will be useful in guiding clinical management strategies in pregnant women with adrenal insufficiency.

The effect of ovarian cancer screening on sexual activity and functioning: results from the UK collaborative trial of ovarian cancer screening RCT

Background:

To examine the impact of multimodal (MMS) and ultrasound (USS) screening on the sexual activity and functioning of 22 966 women in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) RCT.

Methods:

Fallowfield's Sexual Activity Questionnaire (FSAQ) was completed prior to randomisation, then annually in a random sample (RS) of women from MMS, USS and control groups. Any women in the study who required repeat screening due to unsatisfactory results formed an Events Sample (ES); they completed questionnaires following an event and annually thereafter.

Results:

Over time in the RS (n=1339) there was no difference between the MMS and USS groups in sexual activity compared with controls. In the ES there were significant differences between the USS group (n=10 156) and the MMS group (n=12 810). The USS group had lower pleasure scores (mean difference=−0.14, P=0.046). For both groups women who had ⩾2 repeat screens, showed a decrease in mean pleasure scores compared with their annual scores (mean difference=−0.16, P=0.005). Similarly mean pleasure scores decreased following more intensive screens compared with annual screening (mean difference=−0.09, P=0.046).

Conclusions:

Ovarian cancer screening did not affect sexual activity and functioning unless a woman had abnormal results and underwent repeated or higher level screening.

New PCOS-like phenotype in older infertile women of likely autoimmune adrenal etiology with high AMH but low androgens

How anti-Müllerian hormone (AMH) and testosterone (T) interrelate in infertile women is currently largely unknown. We, therefore, in a retrospective cohort study investigated how infertile women with high-AMH (AMH ≥75th quantile; n=144) and with normal-AMH (25th-75th quantile; n=313), stratified for low-T (total testosterone ≤19.0ng/dL), normal-T (19.0-29.0ng/dL) and high-T (>29.0ng/dL) phenotypically behaved. Patient age, follicle stimulating hormone (FSH), dehyroepiandrosterone (DHEA), DHEA sulphate (DHEAS), cortisol (C), adrenocorticotrophic hormone (ACTH), IVF outcomes, as well as inflammatory and immune panels were then compared between groups, with AMH and T as variables. We identified a previously unknown infertile PCOS-like phenotype, characterized by high-AMH but, atypically, low-T, with predisposition toward autoimmunity. It presents with incompatible high-AMH and low-T (<19.0ng/dL), is restricted to lean PCOS-like patients, presenting delayed for tertiary fertility services. Since also characterized by low DHEAS, low-T is likely of adrenal origina, and consequence of autoimmune adrenal insufficiency since also accompanied by low-C and evidence of autoimmunity. DHEA supplementation in such patients equalizes low- to normal-T and normalizes IVF cycle outcomes. Once recognized, this high-AMH/low-T phenotype is surprisingly common in tertiary fertility centers but, currently, goes unrecognized. Its likely adrenal autoimmune etiology offers interesting new directions for investigations of adrenals control over ovarian function via adrenal androgen production.

MANAGEMENT OF ENDOCRINE DISEASE: Epidemiology, quality of life and complications of primary adrenal insufficiency: a review

In this article, we review published studies covering epidemiology, natural course and mortality in primary adrenal insufficiency (PAI) or Addison's disease. Autoimmune PAI is a rare disease with a prevalence of 100-220 per million inhabitants. It occurs as part of an autoimmune polyendocrine syndrome in more than half of the cases. The patients experience impaired quality of life, reduced parity and increased risk of preterm delivery. Following a conventional glucocorticoid replacement regimen leads to a reduction in bone mineral density and an increase in the prevalence of fractures. Registry studies indicate increased mortality, especially evident in patients diagnosed with PAI at a young age and in patients with the rare disease autoimmune polyendocrine syndrome type-1. Most notably, unnecessary deaths still occur because of adrenal crises. All these data imply the need to improve the therapy and care of patients with PAI.

[Addison's disease : Primary adrenal insufficiency]

Adrenal insufficiency, a rare disorder which is characterized by the inadequate production or absence of adrenal hormones, may be classified as primary adrenal insufficiency in case of direct affection of the adrenal glands or secondary adrenal insufficiency, which is mostly due to pituitary or hypothalamic disease. Primary adrenal insufficiency affects 11 of 100,000 individuals. Clinical symptoms are mainly nonspecific and include fatigue, weight loss, and hypotension. The diagnostic test of choice is dynamic testing with synthetic ACTH. Patients suffering from chronic adrenal insufficiency require lifelong hormone supplementation. Education in dose adaption during physical and mental stress or emergency situations is essential to prevent life-threatening adrenal crises. Patients with adrenal insufficiency should carry an emergency card and emergency kit with them.

The importance of adrenal hypoandrogenism in infertile women with low functional ovarian reserve: a case study of associated adrenal insufficiency

BACKGROUND

Low testosterone (T), whether due to ovarian and/or adrenal insufficiency, usually results in poor follicle maturation at small growing follicle stages. The consequence is a phenotype of low functional ovarian reserve (LFOR), characterized by poor granulosa cell mass, low anti-Müllerian hormone and estradiol but rising follicle stimulating hormone. Such hypoandrogenism can be of ovarian and/or adrenal origin. Dehydroepiandrosterone sulfate (DHEAS) is exclusively produced by adrenals and, therefore, reflects adrenal androgen production in the zona reticularis. We here determined in a case study of infertile women with LFOR the presence of adrenal hypoandrogenism, its effects on ovarian function, and the possibility of presence of concomitant adrenal insufficiency (AI), thus reflecting insufficiency of all three adrenal cortical zonae.

METHODS

We searched our center's anonymized electronic research database for women with LFOR, who were also characterized by peripheral adrenal hypoandrogenemia (total testosterone < 16.9 ng/dL) and low DHEAS (<76.0 μg/dL). Among 225 women with LFOR, we identified 29 (12.9 %). The adrenal function of so identified women were further investigated with morning cortisol and ACTH levels and/or standard ACTH stimulation tests. We also determined the prevalence of classical AI (insufficiency glucocorticoid production by zona fasciculata) in hypoandrogenic women with LFOR, and impact of adrenal hypoandrogenism on ovaries.

RESULTS

Among 14/28 women with adrenal hypoandrogenism due to insufficiency of the zona reticularis available for follow up, 4 (28.6 %) also demonstrated previously unrecognized classical primary, secondary or tertiary AI due to insufficiency of the zona fasciculata. An additional patient with presenting diagnosis of seemingly primary ovarian insufficiency (POI), demonstrated extremely low T and DHEAS levels, a diagnosis of Addison's disease, and was on glucocorticoid but not androgen supplementation. As her dramatic improvement in ovarian function criteria after androgen supplementation confirmed, her correct diagnosis, therefore, was actually secondary ovarian insufficiency (SOI) due to adrenal hypoandrogenism.

CONCLUSIONS

Women with LFOR, characterized by low T and DHEAS, are also at risk for AI, while women with AI may be at risk for adrenal induced hypoandrogenism and, therefore, SOI. A currently undetermined percentage of POI patients actually are, likely, affected by SOI, a for prognostic reasons highly significant difference in diagnosis.

Associations between peripheral androgens and cortisol in infertile women

Testosterone has in recent years been proven essential for normal growth and maturation of small growing follicles. Concomitantly, low functional ovarian reserve (LFOR), characterized by a small growing follicle pool, has been associated with low testosterone levels, which can be of ovarian and/or adrenal origin. In this study we, therefore, investigated whether peripheral sex steroid precursors and testosterone levels potentially reflect on adrenal function. In a retrospective cohort study of 355 consecutive infertile women, who presented to an academically affiliated fertility center in New York City, we investigated in a series of statistical models whether low peripheral sex steroid precursors and testosterone are associated with peripheral cortisol (C) levels, reflecting adrenal function. To determine potential correlations, we investigated the dehydroepiandrosterone (DHEA), DHEA sulfate (DHEAS), androstenedione (AD), total testosterone (TT), free testosterone (FT); sex hormone binding globulin (SHBG), anti-Müllerian hormone (AMH), thyroid stimulating hormone (TSH) and C in a series of multivariate and logistic regression analyses, utilizing C either as a continuous variable or with cut off <5.0μg/dL, and TT only as a continuous variable. Practically all models demonstrated significant predictability of peripheral sex hormone precursors for C levels, with DHEA demonstrating the strongest and most consistent predictability as an individual parameter and as part of the DHEAS/DHEA ratio. We conclude that in infertile women peripheral sex hormone precursors, especially DHEA, reflect C levels and, therefore, adrenal function. In infertile women, at all ages low levels of sex hormone precursors, therefore, should be considered indications for further adrenal assessments.

Infertility and Reproductive Function in Patients with Congenital Adrenal Hyperplasia: Pathophysiology, Advances in Management, and Recent Outcomes

Individuals with congenital adrenal hyperplasia have reduced fertility. However, reproductive outcomes have improved over the years. This review provides an update on the multiple pathologic processes that contribute to reduced fertility in both sexes, from alterations of the hypothalamic-pituitary-gonadal axis to the direct effect on gonadal function by elevated circulating adrenal androgens. In addition, elevated serum progesterone concentrations may hinder ovulation and embryo implantation in women, whereas in men testicular adrenal rest tumors can be a major cause of infertility. Suppression of adrenal androgen secretion represents the first line of therapy toward spontaneous conception in both sexes.

Genetics of androgen metabolism in women with infertility and hypoandrogenism

Hypoandrogenism in women with low functional ovarian reserve (LFOR, defined as an abnormally low number of small growing follicles) adversely affects fertility. The androgen precursor dehydroepiandrosterone (DHEA) is increasingly used to supplement treatment protocols in women with LFOR undergoing in vitro fertilization. Due to differences in androgen metabolism, however, responses to DHEA supplementation vary between patients. In addition to overall declines in steroidogenic capacity with advancing age, genetic factors, which result in altered expression or enzymatic function of key steroidogenic proteins or their upstream regulators, might further exacerbate variations in the conversion of DHEA to testosterone. In this Review, we discuss in vitro studies and animal models of polymorphisms and gene mutations that affect the conversion of DHEA to testosterone and attempt to elucidate how these variations affect female hormone profiles. We also discuss treatment options that modulate levels of testosterone by targeting the expression of steroidogenic genes. Common variants in genes encoding DHEA sulphotransferase, aromatase, steroid 5α-reductase, androgen receptor, sex-hormone binding globulin, fragile X mental retardation protein and breast cancer type 1 susceptibility protein have been implicated in androgen metabolism and, therefore, can affect levels of androgens in women. Short of screening for all potential genetic variants, hormonal assessments of patients with low testosterone levels after DHEA supplementation facilitate identification of underlying genetic defects. The genetic predisposition of patients can then be used to design individualized fertility treatments.

Diagnosis and management of adrenal insufficiency

Adrenal insufficiency continues to be a challenge for patients, their physicians, and researchers. During the past decade, long-term studies have shown increased mortality and morbidity and impaired quality of life in patients with adrenal insufficiency. These findings might, at least partially, be due to the failure of glucocorticoid replacement therapy to closely resemble physiological diurnal secretion of cortisol. The potential effect of newly developed glucocorticoid drugs is a focus of research, as are the mechanisms potentially underlying increased morbidity and mortality. Adrenal crisis remains a threat to lives, and awareness and preventative measures now receive increasing attention. Awareness should be raised in medical teams and patients about adrenal insufficiency and management of adrenal crisis to improve clinical outcome.

Is DHEA replacement beneficial in chronic adrenal failure?

Although dehydroepiandrosterone (DHEA) and its sulphate ester dehydroepiandrosterone sulphate (DHEAS) are the most abundant steroid hormones in the human circulation, its exact physiological role is not yet fully understood. In patients with adrenal insufficiency, secretion of DHEA is impaired, leading to decreased circulating DHEA and DHEAS levels, and to androgen deficiency in women. Replacement of DHEA in patients with adrenal insufficiency positively influence mood, sexuality and subjective health status. These effects are generally moderate and show high inter-individual variability. Limited evidence exists for immunomodulatory effects of DHEA. Although an increase of IGF-I levels has been documented, relevant effects on body composition, metabolic or cardiovascular parameters has not been observed in patients with adrenal insufficiency receiving DHEA. Larger-scale phase III studies are still lacking; therefore, initiation of DHEA replacement is decided on an individual basis, focussing on those patients with impaired well-being associated with signs and symptoms of androgen deficiency.

Reproductive outcomes and nononcologic complications after radioactive iodine ablation for well-differentiated thyroid cancer

BACKGROUND

Radioactive iodine (RAI) ablation is frequently performed after initial surgery for well-differentiated thyroid cancer (WDTC). We examined the frequency and timing of childbirth as well as nononcologic complications after RAI ablation for WDTC on a population level.

METHODS

A retrospective cohort study of 25,333 patients (18,850 women) with WDTC was performed using the California Cancer Registry and California Office of Statewide Health Planning and Development database, 1999-2008. The primary outcomes were birthrate and median time to first live birth among women of childbearing age. Secondary outcomes were nononcologic diagnoses occurring outside the acute setting (>30 days) after ablation.

RESULTS

RAI ablation did not affect birthrate among women in the full dataset. However, in subgroup analyses, birthrate among women age 35-39 was significantly decreased in those who received RAI versus those who did not (11.5 versus 16.3 births per 1000 woman-years, p<0.001). Median time to first live birth after diagnosis of WDTC was prolonged among women who received RAI compared to those who did not (34.5 versus 26.1 months; p<0.0001). When 5-year age groups were examined individually, delay to first live birth was observed in women age 20-39 (p<0.05). This remained significant after adjustment for tumor characteristics, socioeconomic status, and marital status. The only nononcologic, nonreproductive adverse effect associated with RAI ablation was an increased rate of nasolacrimal stenosis (RR 3.44, p<0.0001).

CONCLUSIONS

RAI ablation is associated with delayed childbearing in women across most of the reproductive lifespan, and with decreased birthrate in the late reproductive years. The underlying mechanism likely involves physician recommendation to delay pregnancy, as well as a potential impact of RAI on both reproductive choice and reproductive health. Further investigation is merited.

Health-related quality of life in primary and secondary adrenal insufficiency

Adrenal insufficiency (AI) is characterized by a deficient production of glucocorticoids with or without associated mineral corticoid and/or adrenal androgen deficiencies. Despite the low prevalence of AI, its impact on the affected patient is very high, and can be life-threatening disease if not adequately treated. Several glucocorticoid treatment regimens are available, but none is capable of perfectly imitating the cortisol circadian rhythm. Cortisol rhythmicity and treatment of other possible concomitant conditions often associated (e.g., autoimmune disorders and panhypopituitarism) are essential to improve outcome of AI. Morbidity often present in treated AI include an unhealthy metabolic profile, bad quality of sleep, infertility, sexual dysfunction and worse health-related quality of life. This review focuses on psychological morbidity and impaired quality of life in patients with primary or secondary AI of any origin, including a special section devoted to congenital adrenal hyperplasia.

Adrenal diseases during pregnancy: pathophysiology, diagnosis and management strategies

: Adrenal diseases--including disorders such as Cushing's syndrome, Addison's disease, pheochromocytoma, primary hyperaldosteronism and congenital adrenal hyperplasia--are relatively rare in pregnancy, but a timely diagnosis and proper treatment are critical because these disorders can cause maternal and fetal morbidity and mortality. Making the diagnosis of adrenal disorders in pregnancy is challenging as symptoms associated with pregnancy are also seen in adrenal diseases. In addition, pregnancy is marked by several endocrine changes, including activation of the renin-angiotensin-aldosterone system and the hypothalamic-pituitary-adrenal axis. The aim of this article was to review the pathophysiology, clinical manifestation, diagnosis and management of various adrenal disorders during pregnancy.

Involvement of androgens in ovarian health and disease

In women, ovary and adrenal gland produce androgens. Androgens are essential drivers of the primordial to antral follicle development, prior to serving as substrate for estrogen production in the later stages of folliculogenesis. Androgens play a crucial role in the follicular-stromal intertalk by fine tuning the extracellular matrix and vessel content of the ovarian stroma. Local auto-and paracrine factors regulate androgen synthesis in the pre-antral follicle. Androgen excess is a hallmark of polycystic ovary syndrome and is a key contributor in the exaggerated antral follicle formation, stromal hyperplasia and hypervascularity. Hyperandrogenaemia overrides the follicular-stromal dialog, resulting in follicular arrest and disturbed ovulation. On the other hand, androgen deficiency is likely to have a negative impact on fertility as well, and further research is needed to examine the benefits of androgen-replacement therapy in subfertility.

Adrenal insufficiency in pregnancy: challenging issues in diagnosis and management

Adrenal insufficiency (AI) in pregnancy is relatively rare, but it is associated with significant maternal and fetal morbidity and mortality if untreated during gestation or in the puerperium. Hence, timely diagnosis and decisive treatment by the clinician are critical. However, due to pregnancy-induced metabolic and endocrine changes and the resemblance of symptomatology of AI to those of pregnancy, the diagnosis is often difficult to recognize and challenging to confirm. Normal pregnancy is a state of glucocorticoid excess particularly in the latter stages, and normative values for serum cortisol levels are not well-established. Furthermore, testing the hypothalamic-pituitary-adrenal axis using validated stimulation tests during pregnancy are lacking. Therefore, it is the aim of the present review to discuss and to summarize the current knowledge, focussing on the challenges in recognizing AI in pregnancy and interpreting the diagnostic tests, and to propose a clinical approach for optimizing the management of AI in women diagnosed before or during pregnancy.

Global gene expression analysis in human uterine epithelial cells defines new targets of glucocorticoid and estradiol antagonism

In preparation for embryo implantation and pregnancy, the uterine epithelium undergoes a genomic and biological transition that mediates adhesion and invasion of the blastocyst. These events resemble an inflammatory response, and the immune system likely takes an active role in the establishment and maintenance of pregnancy. Although glucocorticoids are primary mediators of the immune system, the functional role of glucocorticoid signaling in the uterine epithelium is not well defined. To investigate the dynamic relationship between glucocorticoids and reproductive hormones, we performed whole-genome microarray analysis in a human uterine endometrial cancer cell line (ECC1 cells) treated with the synthetic glucocorticoid dexamethasone (Dex) alone or in combination with estradiol (E₂). Over 10,000 genes were significantly regulated in the presence of Dex and/or E₂. Surprisingly, unique targets of Dex and E₂ together represented the largest group of regulated genes. Ingenuity pathway analysis found both overlapping and independent regulated networks for each hormone. Several hundred genes were found to be coregulated by Dex and E₂, including several that were antagonistically regulated. The effects of glucocorticoids and E₂ are mediated primarily through the glucocorticoid receptor (NR3C1) and estrogen receptor (ESR1), respectively. In silico promoter analysis revealed that NR3C1 and ESR1 response elements are enriched in antagonistically regulated genes, and signaling through these receptors was required for antagonism. Glucocorticoid and E₂ antagonism of target genes may represent a critical junction between the immune system and female reproductive system. Moreover, identification and ontology analysis of glucocorticoid-regulated genes in a uterine epithelial-like cell line suggests that glucocorticoid signaling regulates important biological functions, including immune cell trafficking and embryonic development.

Multisteroid LC-MS/MS assay for glucocorticoids and androgens, and its application in Addison's disease

OBJECTIVE

Liquid chromatography-mass spectrometry (LC-MS/MS) offers superior analytical specificity compared to immunoassays, but is not available in many regions and hospital due to expensive instrumentation and tedious sample preparation. Thus, we developed an automated, high-throughput LC-MS/MS assay for simultaneous quantification of 10 endogenous and synthetic steroids targeting diseases of the hypothalamo-pituitary-adrenal-axis and gonads.

METHODS

Deuterated internal standards were added to 85µl serum and processed by liquid-liquid-extraction. Cortisol, cortisone, prednisolone, prednisone, 11-deoxycortisol, dexamethasone, testosterone, androstenedione and progesterone were resolved by ultra-high pressure chromatography on a reversed-phase column in 6.1 minutes, and detected by triple-quadrupole MS. The method was used to assess steroid profiles in women with Addison's disease (AD, n=156) and blood donors (BD, n=102).

RESULTS

Precisions ranged 4.5-10.1% RSD, accuracies 95-108%, and extraction recoveries 60-84%. The method was practically free of matrix effects and robust to individual differences in serum composition. Most postmenopausal AD women had extremely low androstenedione below 0.14 nmol/L and median testosterone 0.15 nmol/L [interquartile range 0.00-0.41], considerably lower than postmenopausal BD (1.28 nmol/L [0.96-1.64] and 0.65 nmol/L [0.56-1.10], respectively). AD women in fertile years had androstenedione 1.18 nmol/L [0.71-1.76] and testosterone 0.44 nmol/L [0.22-0.63], approximately half of levels found in BD of corresponding age.

CONCLUSION

This LC-MS/MS assay provides highly sensitive and specific assessments of glucocorticoids and androgens with low sample volumes, and is suitable for endocrine laboratories and research. Its utility was demonstrated in a large cohort of women with AD, and the data suggest that women with AD are particularly androgen deficient after menopause.

Drug prescription patterns in patients with Addison's disease: a Swedish population-based cohort study

CONTEXT

There are no published data on drug prescription in patients with Addison's disease (AD).

OBJECTIVE

Our objective was to describe the drug prescription patterns in Swedish AD patients before and after diagnosis compared with population controls.

DESIGN AND SETTING

We conducted a population-based cohort study in Sweden.

PATIENTS

Through the Swedish National Patient Register and the Swedish Prescribed Drug Register, we identified 1305 patients with both a diagnosis of AD and on combination treatment with hydrocortisone/cortisone acetate and fludrocortisone. Direct evidence of the AD diagnosis from patient charts was not available. We identified 11 996 matched controls by the Register of Population.

MAIN OUTCOME MEASURE

We determined the ratio of observed to expected number of patients treated with prescribed drugs.

RESULTS

Overall, Swedish AD patients received more prescribed drugs than controls, and 59.3% of the AD patients had medications indicating concomitant autoimmune disease. Interestingly, both before and after the diagnosis of AD, patients used more gastrointestinal medications, antianemic preparations, lipid-modifying agents, antibiotics for systemic use, hypnotics and sedatives, and drugs for obstructive airway disease (all P values < .05). Notably, an increased prescription of several antihypertensive drugs and high-ceiling diuretics was observed after the diagnosis of AD.

CONCLUSION

Gastrointestinal symptoms and anemia, especially in conjunction with autoimmune disorders, should alert the physician about the possibility of AD. The higher use of drugs for cardiovascular disorders after diagnosis in patients with AD raises concerns about the replacement therapy.

What is the best diagnostic and therapeutic management strategy for an Addison patient during pregnancy?

A new diagnosis of primary adrenal insufficiency (PAI) during pregnancy is extremely rare and difficult to recognize as signs and symptoms such as nausea, fatigue and hypotension may resemble features of normal pregnancy. However, if the diagnosis is overlooked and steroid replacement delayed, subsequent adrenal crisis triggered by hyperemesis gravidarum, fever or delivery can cause severe maternal and foetal morbidity and even mortality. In case of clinical suspicion of PAI, we recommend to measure paired samples of cortisol and ACTH and, if clinically feasible, a short synacthen test. We propose trimester-specific pass cut-offs for the short synacthen test that take into account the rise of total and also free cortisol during pregnancy. Empirical hydrocortisone treatment should never be delayed if the clinical suspicion is high. All pregnant women with PAI should be monitored by a team of endocrine and obstetric specialists. The third trimester is physiologically associated with a rise not only in total but also free cortisol and thus requires regular adjustment of the glucocorticoid dose. Mineralocorticoid requirements may change during pregnancy due to the anti-mineralocorticoid properties of progesterone. As plasma renin physiologically increases in pregnancy, monitoring is limited to clinical assessment including blood pressure and serum electrolytes. It is crucial that a pregnant woman with PAI and her partner are well educated regarding the adjustment of glucocorticoid dose in intercurrent illness and that both are trained in hydrocortisone emergency injection techniques. The obstetric staff should be provided with clear and written guidance for hydrocortisone cover during labour and delivery. With the appropriate replacement therapy, PAI patients can expect to have an uneventful pregnancy and deliver a healthy infant.

Chronic systemic administration of serotonergic ligands flibanserin and 8-OH-DPAT enhance HPA axis responses to restraint in female marmosets

BACKGROUND

Flibanserin, a novel serotonin (5-HT)(1A) agonist and 5-HT(2A) antagonist, has been shown to increase sexual desire and reduce distress in women with Hypoactive Sexual Desire Disorder (HSDD). In marmoset monkeys, flibanserin has demonstrated pro-social effects on male-female pairmates, while the classic 5-HT(1A) agonist 8-OH-DPAT suppresses female sexual behavior and increases aggressive interactions between pairmates. Activation of 5-HT(1A) and 5-HT(2A) receptors is known to stimulate the hypothalamic-pituitary-adrenal (HPA) axis. This study aims to characterize the effects of repeated flibanserin and 8-OH-DPAT administration on the marmoset HPA axis and to elucidate endocrine correlates of altered marmoset pair behavior.

METHODS

Adrenocorticotropic hormone (ACTH) and cortisol were examined at baseline and during 5-HT(1A) agonist and restraint challenges in 8 female marmoset monkeys receiving daily flibanserin (15mg/kg) and an additional 8 female marmosets receiving 8-OH-DPAT (0.1mg/kg) for 15-16weeks. Corresponding vehicle treatments were administered in a counterbalanced, within-subject design. All females were housed in stable male-female pairs. Treatment-induced changes in ACTH and cortisol levels were correlated with previously assessed marmoset pair behavior.

RESULTS

While morning basal cortisol levels and HPA responses to a 5-HT(1A) agonist challenge were not altered by chronic flibanserin or 8-OH-DPAT, both treatments increased the responsiveness of the marmoset HPA axis to restraint. Enhanced ACTH responses to restraint correlated with reduced sexual receptivity and increased aggression in 8-OH-DPAT-, but not in flibanserin-treated female marmosets.

CONCLUSIONS

Unaltered HPA responses to a 5-HT(1A) agonist challenge after chronic flibanserin and 8-OH-DPAT treatments indicate little or no de-sensitization of the HPA axis to repeated 5-HT(1A) manipulation. Chronic 8-OH-DPAT, but not flibanserin, leads to aggravated ACTH responses to stress that may contribute to anti-sexual and anti-social behavior between 8-OH-DPAT-treated females and their male pairmates. Despite similar flibanserin and 8-OH-DPAT induced ACTH responses to restraint stress, flibanserin-treated females show unchanged cortisol profiles. This is possibly due to flibanserin's regional selectivity in 5-HT(1A) activation and concurrent 5-HT(2A) inhibition. The contrasting restraint-related cortisol responses emulate contrasting behavioral phenotypes of diminished pair-bond of 8-OH-DPAT-treated females compared to the more affiliative pair-bond of flibanserin-treated females.

Adrenal disorders in pregnancy

Pregnancy is marked by alterations in a number of endocrine systems, including activation of the renin-angiotensin-aldosterone system and the hypothalamic-pituitary-adrenal axis. The placenta, the fetal adrenal glands and the liver constitute an interactive endocrine entity, known as the fetoplacental unit. In the fetoplacental unit, the fetal adrenal glands are the primary source of dehydroepiandrosterone sulphate, which is further metabolized by the fetal liver and placenta to produce a variety of oestrogens. Several disorders can affect both the fetal and maternal adrenal glands during pregnancy. The most common fetal adrenal disorder, steroid 21-hydroxylase deficiency, leads to abnormalities in sexual development and can be life threatening for the neonate. Although rare, maternal adrenal disorders are associated with considerable maternal mortality and morbidity if not promptly recognized and treated. However, diagnosis is often difficult to establish because of the endocrine changes occurring during normal pregnancies and the lack of reference values for the majority of the adrenal steroids. This Review provides an overview of adrenal steroid metabolism during pregnancy and focuses on diagnosis and treatment of the most common fetal and maternal adrenal disorders.

Sexual dysfunctions in men affected by autoimmune Addison's disease before and after short-term gluco- and mineralocorticoid replacement therapy

INTRODUCTION

There is evidence suggesting that autoimmune Addison's disease (AD) could be associated with sexual dysfunctions probably caused by gluco- and mineralocorticoid deficiency; however, no study has yet treated this subject in males.

AIM

To evaluate male sexuality and psychological correlates in autoimmune AD before and after gluco- and mineralocorticoid replacement therapy.

METHODS

Twelve subjects with a first diagnosis of autoimmune AD were studied before (baseline) and 2 months after (recovery phase) initiating hormone replacement therapy.

MAIN OUTCOME MEASURES

Erectile function (EF), orgasmic function (OF), sexual desire (SD), intercourse satisfaction (IS), overall satisfaction (OS), depression, and anxiety were studied using a number of questionnaires (International Index of Erectile Function, Beck Depression Inventory, and Spielberger State-Trait Anxiety Inventory); clinical, biochemical, and hormone data were included in the analysis.

RESULTS

At baseline, low values were found for EF, OF, SD, IS, and OS and high values for depression and anxiety; all of these parameters improved significantly in the recovery phase compared with baseline. EF variation between the two phases correlated significantly and positively with the variation of serum cortisol, urinary free cortisol, systolic blood pressure, and diastolic blood pressure and inversely with that of upright plasma renin activity. Multiple linear regression analysis using EF variation as dependent variable confirmed the relationship of the latter with variation of serum cortisol, urinary free cortisol, and upright plasma renin activity but not with variation of systolic and diastolic blood pressure.

CONCLUSIONS

Our study showed that onset of autoimmune AD in males is associated with a number of sexual dysfunctions, all reversible after initiating replacement hormone therapy; cortisol and aldosterone deficiency seems to play an important role in the genesis of erectile dysfunction although the mechanism of their activity is not clear.

What is the best long-term management strategy for patients with primary adrenal insufficiency?

Primary adrenal insufficiency is treated with glucocorticoid and mineralocorticoid replacement therapy. Recent data revealed that health-related quality of life in adrenal insufficiency is impaired in many patients and that patients with adrenal insufficiency are also threatened by an increased mortality and morbidity. This may be caused by inadequate glucocortiocid therapy and adrenal crisis. Therefore, the optimization of hormone replacement therapy remains one of the most challenging tasks in endocrinology because it is largely based on clinical grounds because of the lack of objective assessment tools. This article provides answers to the important daily clinical questions, such as correct dose finding, dose adaptation in special situations, e g, pregnancy, improvement of quality of life and measures for protection from adrenal crisis. Other important aspects discussed are side effects of glucocortiocid replacement therapy and interactions with other drugs.
