Cardiometabolic Aspects of Congenital Adrenal Hyperplasia.

Treatment of classic congenital adrenal hyperplasia (CAH) is directed at replacing deficient hormones and reducing androgen excess. However, even in the era of early diagnosis and lifelong hormonal substitution, the presence of CAH is still associated with numerous complications and also with increased mortality. The aim of this article was to create an authoritative and balanced review concerning cardiometabolic risk in patients with CAH. The authors searched all major databases and scanned reference lists of all potentially eligible articles to find relevant articles. The risk was compared with that in other forms of adrenal insufficiency. The reviewed articles, most of which were published recently, provided conflicting results, which can be partially explained by differences in the inclusion criteria and treatment, small sample sizes and gene-environmental interactions. However, many studies showed that the presence of CAH is associated with an increased risk of weight gain, worsening of insulin sensitivity, high blood pressure, endothelial dysfunction, early atherosclerotic changes in the vascular wall and left ventricular diastolic dysfunction. These complications were more consistently reported in patients with classic than non-classic CAH and were in part related to hormonal and functional abnormalities associated with this disorder and/or to the impact of over- and undertreatment. An analysis of available studies suggests that individuals with classic CAH are at increased cardiometabolic risk. Excess cardiovascular and metabolic morbidity is likely multifactorial, related to glucocorticoid overtreatment, imperfect adrenal hormone replacement therapy, androgen excess and adrenomedullary failure. Cardiometabolic effects of new therapeutic approaches require future targeted studies.

46,XX males with congenital adrenal hyperplasia: a clinical and biochemical description.

Introduction: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) or 11-hydroxylase deficiency (11OHD) is characterized by underproduction of cortisol and overproduction of adrenal androgens. These androgens lead to a variable degree of virilization of the female external genitalia in 46,XX individuals. Especially in developing countries, diagnosis is often delayed and 46,XX patients might be assigned as males. This study aims to describe the clinical and biochemical characteristics of a unique cohort of untreated male-reared 46,XX classic CAH patients from Indonesia and discusses treatment challenges. Methods: Nine untreated classic CAH patients with 46,XX genotype and 21OHD (n=6) or 11OHD (n=3), aged 3-46 years old, were included. Biometrical parameters, clinical characteristics, and biochemical measurements including glucocorticoids, renin, androgens, and the pituitary-gonadal axis were evaluated. Results: All patients had low early morning serum cortisol concentrations (median 89 nmol/L) without significant increase after ACTH stimulation. Three patients with salt wasting 21OHD reported one or more periods with seizures and/or vomiting in their past until the age of 6, but not thereafter. The remaining patients reported no severe illness or hospitalization episodes, despite their decreased capacity to produce cortisol. In the 21OHD patients, plasma renin levels were elevated compared to the reference range, and in 11OHD patients renin levels were in the low-normal range. All adult patients had serum testosterone concentrations within the normal male reference range. In 21OHD patients, serum 11-oxygenated androgens comprised 41-60% of the total serum androgen concentrations. Glucocorticoid treatment was offered to all patients, but they refused after counseling as this would reduce their endogenous androgen production and they did not report complaints of their low cortisol levels. Discussion: We describe a unique cohort of untreated classic 46,XX male CAH patients without overt clinical signs of cortisol deficiency despite their cortisol underproduction and incapacity to increase cortisol levels after ACTH stimulation. The described adolescent and adult patients produce androgen levels within or above the normal male reference range. Glucocorticoid treatment will lower these adrenal androgen concentrations. Therefore, in 46,XX CAH patients reared as males an individual treatment approach with careful counseling and clear instructions is needed.

Free cortisol and free 21-deoxycortisol in the clinical evaluation of congenital adrenal hyperplasia.

CONTEXT: Some patients with classic congenital adrenal hyperplasia (CAH) survive without glucocorticoid treatment. Increased precursor concentrations in these patients might lead to higher free (biological active) cortisol concentrations by influencing the cortisol-protein binding. In 21-hydroxylase deficiency (21OHD), the most common CAH form, accumulated 21-deoxycortisol (21DF) may further increase glucocorticoid activity. Both mechanisms could explain the low occurrence of symptoms in some untreated classic CAH patients. OBJECTIVE: Develop and validate an LC-MS/MS method for free cortisol and free 21DF to quantify these steroids in untreated patients with classic CAH (n=29), non-classic CAH (NCCAH, n=5), other forms of adrenal insufficiency (AI, n=3), and controls (n=11) before and 60 minutes after Synacthen® administration. RESULTS: Unstimulated total cortisol concentrations of untreated classic CAH patients (median 109 nmol/L) were lower than in untreated NCCAH patients (249 nmol/L, p=0.010) and controls (202 nmol/L, p=0.016), but free cortisol concentrations were similar. Basal free 21DF concentrations were high in 21OHD patients (median 5.32 nmol/L) and undetectable in AI patients and controls (<0.19 nmol/L). After Synacthen® administration, free 21DF concentrations increased in 21OHD patients, while free cortisol concentrations did not change. CONCLUSIONS: Free cortisol concentrations in classic CAH patients were similar to those in controls and NCCAH patients, indicating comparable cortisol availability. Additionally, 21OHD patients produce high concentrations of 21DF, possibly explaining the low occurrence of symptoms in some classic 21OHD patients. Free cortisol and 21DF levels should be considered in evaluating adrenal insufficiency in patients with CAH.

Experience in a PHTS Expertise Centre: Yield of Thyroid Ultrasound Surveillance in Children with PTEN Hamartoma Tumor Syndrome.

Objective: Children with PTEN hamartoma tumor syndrome (PHTS) are at increased risk for developing thyroid abnormalities, including differentiated thyroid carcinoma (DTC). The Dutch PHTS guideline recommends ultrasound surveillance starting from age 18. Since the literature describes PHTS patients who developed DTC before age 18, the Dutch PHTS expertise centre has initiated annual ultrasound surveillance starting from age 12. The purpose of this study was to identify the yield of thyroid ultrasound surveillance in children. Methods: A retrospective single centre cohort study was conducted. Pediatric PHTS patients who received thyroid ultrasound surveillance before age 18 between 2016-2023 were included. Patients' medical records have been reviewed. Primary outcomes included prevalence and time to develop thyroid nodules ≥10mm, nodular growth, goiter, thyroiditis and DTC. Descriptive statistics and Kaplan-Meier analyses were performed. Results: Forty-three patients were included. Two patients (5%) were diagnosed with DTC at ages 12 and 17. Both DTCs were identified as minimally invasive follicular carcinoma at stages pT3NxMx and pT1NxMx respectively. A total of 84% were diagnosed with thyroid abnormalities at a median age of 12 years (range 9-18). Most common findings were benign, including nodular disease (74%), goiter (30%) and autoimmune thyroiditis (12%). Nodular growth was observed in 14 patients (33%) resulting in (hemi)thyroidectomy in 7 patients (16%). Conclusion: Thyroid ultrasound surveillance resulted in the detection of DTC in 2/43 PHTS patients before age 18. These findings support the recommendation to initiate thyroid ultrasound surveillance in children at least from age 12, preferably within an expertise centre.

Reference intervals for serum 11-oxygenated androgens in children.

OBJECTIVE: Classic androgens such as dehydroepiandrosterone, androstenedione, and testosterone are generally measured for diagnosis and treatment monitoring in children and adolescents with hyperandrogenism, as can occur in congenital adrenal hyperplasia, premature pubarche, or polycystic ovarian syndrome. However, adrenally-derived 11-oxygenated androgens also contribute to the androgen pool and should therefore be considered in clinical management. Nevertheless, paediatric reference intervals are lacking. Therefore, we developed a serum assay to establish reference intervals for four 11-oxygenated androgens in addition to four classic androgens. DESIGN: Reference interval study for serum 11-oxygenated androgens in children. METHODS: We developed and validated a sensitive LC-MS/MS assay and quantified eight serum androgens, including four 11-oxygenated androgens, in serum of 256 healthy children (aged 0-17 years old). An age-dependency for all androgens was observed, and therefore we divided the cohort based on age (prepubertal (n=133; 94 boys, 39 girls) and pubertal (n=123; 52 boys, 71 girls)) to compute reference intervals (2.5th - 97.5th percentiles). RESULTS: In the prepubertal group, there was no significant sex-difference for any of the measured androgens. In the pubertal group, androstenedione, testosterone, and dihydrotestosterone showed a significant difference between boys and girls. In contrast, adrenal androgens dehydroepiandrosterone, 11-hydroxyandrostenedione, 11-ketoandrostenedione, 11-hydroxytestosterone, and 11-ketotestosterone did not. CONCLUSIONS: We developed and validated an assay for 11-oxygenated androgens, in addition to four classic androgens and established reference intervals. This enables a comprehensive evaluation of serum androgen status in children with clinical symptoms of hyperandrogenism.

Evaluation of Ex Vivo Adrenocorticotropic Hormone Responsiveness of Human Fetal Testis.

Testicular adrenal rest tumors (TARTs), commonly occurring in males with congenital adrenal hyperplasia, may arise from chronic stimulation of adrenocorticotropic hormone (ACTH)-sensitive cells in the testes. It is not yet established whether the human fetal testis (HFT) is responsive to ACTH. To investigate this, we cultured HFT tissue with and without ACTH for up to 5 days, and quantified adrenal steroid hormones and expression of adrenal steroidogenic enzymes. Fetal testis and adrenal tissue produced high levels of testosterone and cortisol, respectively, indicating viability. In contrast to fetal adrenal tissues, the expression of ACTH receptor MC2R was either absent or expressed at extremely low levels in ex vivo HFT tissue and no clear response to ACTH in gene expression or steroid hormone production was observed. Altogether, this study suggests that the HFT is unresponsive to ACTH, which would indicate that a TART does not arise from fetal testicular cells chronically exposed to ACTH in utero.

Hormonal control during infancy and testicular adrenal rest tumor development in males with congenital adrenal hyperplasia: a retrospective multicenter cohort study.

IMPORTANCE: Testicular adrenal rest tumors (TARTs), often found in male patients with congenital adrenal hyperplasia (CAH), are benign lesions causing testicular damage and infertility. We hypothesize that chronically elevated adrenocorticotropic hormone exposure during early life may promote TART development. OBJECTIVE: This study aimed to examine the association between commencing adequate glucocorticoid treatment early after birth and TART development. DESIGN AND PARTICIPANTS: This retrospective multicenter (n = 22) open cohort study collected longitudinal clinical and biochemical data of the first 4 years of life using the I-CAH registry and included 188 male patients (median age 13 years; interquartile range: 10-17) with 21-hydroxylase deficiency (n = 181) or 11-hydroxylase deficiency (n = 7). All patients underwent at least 1 testicular ultrasound. RESULTS: TART was detected in 72 (38%) of the patients. Prevalence varied between centers. When adjusted for CAH phenotype, a delayed CAH diagnosis of >1 year, compared with a diagnosis within 1 month of life, was associated with a 2.6 times higher risk of TART diagnosis. TART onset was not predicted by biochemical disease control or bone age advancement in the first 4 years of life, but increased height standard deviation scores at the end of the 4-year study period were associated with a 27% higher risk of TART diagnosis. CONCLUSIONS AND RELEVANCE: A delayed CAH diagnosis of >1 year vs CAH diagnosis within 1 month after birth was associated with a higher risk of TART development, which may be attributed to poor disease control in early life.

Quality of life in men with Klinefelter syndrome: a multicentre study.

Background: Klinefelter syndrome (KS) is associated with an increased risk of lower socioeconomic status and a higher risk for morbidity and mortality, which may have a significant impact on quality of life (QOL). The objective of this study is to investigate QOL in a large European cohort of men with KS. Design: Cross-sectional multicentre study. Methods: Two-hundred-eighteen men with KS were recruited from 14 clinical study centres in 6 European countries which participated in the European dsd-LIFE study. Male normative data from a healthy and a psychiatric reference population were used for comparison. The validated World Health Organization (WHO) QOL (WHOQOL)-BREF questionnaire was used to investigate five main domains of quality of life (WHOQOL): global, physical, psychological, environment, and social. Results: The QOL physical domain score was lower for men with KS compared to the healthy reference population (KS: 66.9; s.d. 19.4, n = 193; healthy reference population: 76.5; s.d. 16.2, n = 1324, P < 0.001) but higher compared to the psychiatric reference population (54.6; s.d. 20.6; n = 77, P < 0.001). The WHOQOL-psychological domain score was lower for men with KS compared to the healthy reference population (KS: 63.6; s.d. 17.8, n = 193; healthy reference population: 67.8; s.d. 15.6, n = 1324, P < 0.05) but higher compared to the psychiatric reference population (45.9; s.d. 26.0), n = 77, P < 0.001). The social domain score on the WHOQOL questionnaire was found to be lower in men with Klinefelter syndrome (KS) compared to the healthy reference population (KS: 60.0; s.d. 21.6, n = 193; healthy reference population: 68.2; s.d. 13.8, n = 1324, P < 0.001). However, this score was similar to that of the psychiatric reference population (61.0; s.d. 17.0, n = 77, P = 0.5). The WHO environment domain score of men with KS (70.0; s.d. 15.0, n = 193) was similar to the healthy reference population (70.5; s.d. 20.7, n = 1324) but higher compared to the psychiatric reference population (61.9; s.d. 20.8, n = 77, P = 0.002). Experienced discrimination, less social activities, and the presence of chronic health problems were associated with significantly decreased QOL in men with KS. Conclusion: Overall QOL in European men with KS is significantly worse compared to a healthy European reference population. Especially, the presence of discrimination, less social activities, and chronic health problems is associated with lower physical, psychological, and social QOL. Further studies are necessary to investigate if a multidisciplinary approach may help to provide adequate counselling and psychosocial support to improve QOL.

[Children and adolescents with gender questions: dilemmas in the hormonal treatment by multidisciplinary teams]. / Jongeren met genderincongruentie.

In the Netherlands but also in many other countries, there is an increasing social discussion about gender identity and gender diversity, and an increasing number of children and adolescents are seeking medical help because of questions about their gender identity. The cause of this increase is still unknown. Gender questions are diverse and require an individual approach by a multidisciplinary team. A number of adolescents have additional problems such as mood problems, autistiform symptoms and systemic problems. Diagnosis and treatment takes place in accordance with the quality standard for transgender care somatic and psychological. Hormonal treatment can help to reduce gender dysphoria and improve mental health.

The clinical characteristics and quality of life of 248 pediatric and adult patients with Congenital Adrenal Hyperplasia.

Background: Congenital Adrenal Hyperplasia (CAH) is a chronic disease that requires lifelong treatment. Patients may face stigmatization, which may affect their quality of life (QoL). Therefore, we assessed the clinical characteristics and QoL of patients with CAH in the Middle East. Methods: This case-control study included patients with CAH aged >5 years from two tertiary centers (2020-2021). The patients were matched to a healthy control group and were then divided into pediatric and adult groups. Data were collected from their electronic medical records. Additionally, the EQ-5D-5L QoL questionnaire was completed by both the patients and control group to assess five domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). Results: The study included 248 patients with CAH (females: 58.8%), with a family history of the condition (57.3%) and/or parental consanguinity (68.1%). The most frequently reported gene defect was CYP21A2, while the most commonly reported symptoms/signs were ambiguous genitalia and obesity. Almost all female patients had received corrective surgery. The questionnaire response rate was 86.3% (n=214/248). The CAH patient group's mean total QoL score was 85.2 compared with 99.8 in the control. Further, CAH patients had lower QoL scores in all domains compared to those in the control group (p ≤ 0.0001-0.0023). The pain/discomfort and anxiety/depression domains were affected significantly more than the other domains were, with 47.7% and 44.4% participants, respectively, p<0.0001. Additionally, obesity was found to be a predictor of reduced mobility following a logistic regression analysis (p ≤ 0.04, OR (0.18-0.98)). Conclusion: Patients with CAH reported lower QoL overall, particularly in the pain/discomfort and anxiety/depression domains. Based on this, we recommend the early involvement of psychologists in a multidisciplinary team approach, pre-marital screening, and the implementation of awareness programs for people diagnosed with CAH in communities with high consanguineous mating.

Novel likely pathogenic variant in NR5A1 gene in a Tanzanian child with 46,XY differences of sex development, inherited from the mosaic father.

Summary: Pathogenic variants in the nuclear receptor subfamily 5 group A member 1 gene (NR5A1), which encodes steroidogenic factor 1 (SF1), result in 46,XY and 46,XX differences of sex development (DSD). In 46,XY individuals with a pathogenic variant in the NR5A1 gene a variable phenotype ranging from mild to severe is seen, including adrenal failure, testis dysgenesis, androgen synthesis defects, hypospadias and anorchia with microphallus and infertility. We report the clinical, endocrinological and genetic characteristics of a patient with 46,XY DSD with a novel likely pathogenic missense variant in the NR5A1 gene. A retrospective evaluation of the medical history, physical examination, limited endocrinological laboratory analysis and genetic analysis with DSD gene panel testing was performed. A 1.5-month-old individual was referred with ambiguous genitalia. The karyotype was 46,XY. The endocrinological analyses were within normal male reference including a normal response of cortisol within an adrenocorticotropic hormone test. A novel heterozygous missense variant c.206G>C p.(Arg69Pro) in the NR5A1 gene was detected. This variant was present in mosaic form (~20%) in his unaffected father. Because another missense variant at the same position and other missense variants involving the same highly conserved codon have been reported, we consider this NR5A1 variant in this 46,XY DSD patient as likely pathogenic in accordance with the ACMG/AMP 2015 guidelines causing ambiguous genitalia but no adrenal insufficiency. This variant was inherited from the apparently unaffected mosaic father, which might have implications for the recurrence risk in this family. Learning points: The importance of performing trio (patient and parents) sequencing is crucial in pointing out the origin of inheritance. In a 46,XY differences of sex development patient, a normal adrenal function does not rule out an NR5A1 mutation. With the support of a dedicated overseas institute partnership, we could solve this complex clinical case by molecular diagnosis in a resource-limited setting.

Measuring steroids in hair opens up possibilities to identify congenital adrenal hyperplasia in developing countries.

OBJECTIVE: Patients with congenital adrenal hyperplasia (CAH) in developing countries have limited access to appropriate laboratory facilities for diagnosis and follow-up. The aim of this study is to evaluate steroid measurement in hair as a diagnostic tool to identify and monitor CAH in these patients. DESIGN: A method was developed to measure steroids in hair, the stability of steroids in hair was assessed, and the concentration range in healthy volunteers was determined. Hair samples of patients, before and after starting therapy, were transported at ambient temperature to The Netherlands for analysis. PATIENTS: Twenty-two Indonesian CAH patients and 84 healthy volunteers participated. MEASUREMENTS: Cortisol, 17-hydroxyprogesterone (17OHP), androstenedione, and testosterone in hair were measured by liquid chromatography with tandem mass spectrometry. RESULTS: Steroids in hair could be measured and remained stable (<4.9% deviation) for at least 3 weeks at 4°C and 30°C. In each of the untreated patients, hair concentrations of 17OHP (9.43-1135 pmol/g), androstenedione (36.1-432 pmol/g), and testosterone (2.85-69.2 pmol/g) were all above the upper limit of the corresponding range in healthy volunteers; 5.5 pmol/g, 13 pmol/g, and 1.8 pmol/g, respectively. After starting glucocorticoid treatment, the steroid concentrations in the hair of CAH patients decreased significantly for androstenedione (73%) and testosterone (59%) after 6 months. CONCLUSIONS: CAH could be confirmed in Indonesian patients based on the concentration of 17OHP, androstenedione, and testosterone in hair, and a treatment effect was observed. These findings open up opportunities to diagnose and/or monitor CAH in developing countries with a simple noninvasive technique.

Challenges in treatment of patients with non-classic congenital adrenal hyperplasia.

Congenital adrenal hyperplasia (CAH) due to 21α-hydroxylase deficiency (21OHD) or 11ß-hydroxylase deficiency (11OHD) are congenital conditions with affected adrenal steroidogenesis. Patients with classic 21OHD and 11OHD have a (nearly) complete enzyme deficiency resulting in impaired cortisol synthesis. Elevated precursor steroids are shunted into the unaffected adrenal androgen synthesis pathway leading to elevated adrenal androgen concentrations in these patients. Classic patients are treated with glucocorticoid substitution to compensate for the low cortisol levels and to decrease elevated adrenal androgens levels via negative feedback on the pituitary gland. On the contrary, non-classic CAH (NCCAH) patients have more residual enzymatic activity and do generally not suffer from clinically relevant glucocorticoid deficiency. However, these patients may develop symptoms due to elevated adrenal androgen levels, which are most often less elevated compared to classic patients. Although glucocorticoid treatment can lower adrenal androgen production, the supraphysiological dosages also may have a negative impact on the cardiovascular system and bone health. Therefore, the benefit of glucocorticoid treatment is questionable. An individualized treatment plan is desirable as patients can present with various symptoms or may be asymptomatic. In this review, we discuss the advantages and disadvantages of different treatment options used in patients with NCCAH due to 21OHD and 11OHD.

Transcriptional comparison of testicular adrenal rest tumors with fetal and adult tissues.

Background: Testicular adrenal rest tumors (TART) are a common complication of unknown cellular origin in patients with congenital adrenal hyperplasia (CAH). These benign tumors have both adrenal and testicular characteristics and are hypothesized to either derive from cells of adrenal origin from the fetal adrenogonadal primordium or by atypical differentiation of adult Leydig-progenitor cells. Objective: This study aims to unravel the identity and etiology of TART. Methods: Co-expression of adrenal-specific CYP11B1 and Leydig cell-specific HSD17B3 in TART was studied using immunohistochemistry. We studied the possibility of TART being derived from atypical differentiation of adult Leydig-progenitor cells by the quantification of adrenal-specific enzyme expression upon adrenocorticotrophic hormone (ACTH)-like stimulation of ex vivo cultured platelet-derived growth factor receptor alpha-positive cells. By comparing the transcriptome of TART (n = 16) with the transcriptome of fetal adrenal (n = 13), fetal testis (n = 5), adult adrenal (n = 11), and adult testis (n = 10) tissues, we explored the identity of TART. Results: We demonstrate co-expression of adrenal-specific CYP11B1 and testis-specific HSD17B3 in TART cells, indicating the existence of a distinct TART cell exhibiting both adrenal and testicular characteristics. Ex vivo cultured adult Leydig-progenitor cells did not express the ACTH-receptor MC2R but did express CYP11B1 upon stimulation. Unsupervised clustering of transcriptome data showed that TART was most similar to adult adrenal tissue, followed by adult testis tissue, and least similar to either fetal tissue. Conclusion: Our data suggest that TART is induced - most likely via activation of a cAMP/protein kinase A-dependent receptor - from a progenitor cell into a unique mature adrenal-like cell type, sometimes exhibiting both adrenal and testicular features.

Identification of a Novel CYP11B2 Variant in a Family with Varying Degrees of Aldosterone Synthase Deficiency.

Isolated aldosterone synthase deficiency is a rare autosomal recessive disorder caused by pathogenic variants in CYP11B2, resulting in impaired aldosterone synthesis. We report on a neonate with isolated aldosterone synthase deficiency caused by a novel homozygous CYP11B2 variant Chr8:NM_000498.3:c.400G>A p.(Gly134Arg). The patient presented shortly after birth with severe signs of aldosterone deficiency. Interestingly, segregation analysis revealed that the patient's asymptomatic father was also homozygous for the CYP11B2 variant. Biochemical evaluation of the father indicated subclinical enzyme impairment, characterized by elevated aldosterone precursors. Apparently, this homozygous variant led to different clinical phenotypes in two affected relatives. In this manuscript we elaborate on the performed biochemical and genetic work-up and describe potential pitfalls of CYP11B2 sequencing due to its homology to CYP11B2.

The impact of Klinefelter syndrome on socioeconomic status: a multicenter study.

Klinefelter syndrome (KS) is associated with an increased risk of neuropsychological morbidity, such as learning disabilities, which may have a significant impact on socioeconomic status (SES). The objective of this study was to investigate the SES in men with KS and to associate this outcome with social participation, age at diagnosis, testosterone therapy and physical and mental health status. Men with KS were recruited in 14 clinical study centers in six European countries which participated in the European dsd-LIFE study. Two hundred five men with KS were eligible for inclusion. Male normative data from the European Social Surveys (ESS) were used for comparison. Data related to education, occupation, satisfaction with income and householding were collected. Compared to the ESS reference population, fewer men with KS achieved a high level of education (13% vs 25%, P < 0.001). There was a significant difference in having a paid job (55% vs 66%, P < 0.001), and the percentage of absence by sickness or disability was higher among men with KS (10% vs 3%, P < 0.001). Furthermore, satisfaction with current household's income was lower (32% vs 42%, P < 0.01). Lower scores for subjective general health were associated with lower scores for these outcomes. Men with KS achieve on average lower levels of education, occupation and report less satisfaction with income compared to the ESS reference population. The presence of health problems and lower scores of subjective general health was related to lower levels of occupation and lower satisfaction with income in men with KS.

Management of Acute Adrenal Insufficiency-Related Adverse Events in Children with Congenital Adrenal Hyperplasia: Results of an International Survey of Specialist Centres.

INTRODUCTION: There is wide variation in reported rates of acute adrenal insufficiency (AI)-related adverse events (sick day episodes and adrenal crises) between centres. This study aimed to evaluate the level of consensus on criteria considered essential for defining and managing these events in children with Congenital Adrenal Hyperplasia. METHODS: Active users of the International Congenital Adrenal Hyperplasia and International Disorders of Sex Development (I-CAH/I-DSD) Registries (n = 66), non-active users of I-CAH/I-DSD (n = 35), and the EuRRECa e-Reporting Registry (n = 10) were approached to complete an online survey. RESULTS: Fifty-six centres from 27 countries responded to the survey; the response rates for the three groups were 42 (65%), 11 (31%), and 3 (30%), respectively. Steroid management plans, one to one patient education, and contact details of health care staff were provided by over 90% of centres in high-income countries. All 56 centres advised glucocorticoid stress dosing in the event of fever. Less common indications for sick day dosing included vaccination and mild afebrile intercurrent illness, recommended by 17 (30%) and 9 (16%) centres, respectively. The most frequently reported stress dosing regimens were tripling the total daily dose of hydrocortisone and administering 3 times daily and doubling or tripling the largest daily hydrocortisone dose depending on the nature of the trigger and administering 3 times daily, recommended by 24 (43%) and 21 (38%) centres, respectively. Vomiting was the most common indication for intramuscular hydrocortisone injection, reported by 34 (61%) centres. Over 50% of respondents indicated that essential clinical criteria for adrenal crisis should include fatigue and nausea or vomiting and over 60% indicated that hypotension, hyponatraemia, hyperkalaemia, and clinical improvement following parenteral glucocorticoids were essential criteria. In the event of an adrenal crisis, 47 (84%) reported that the majority of patients were admitted to hospital. For the management of an adrenal crisis, a bolus parenteral injection of hydrocortisone was the most frequently administered medication, reported by 50 (89%) centres. CONCLUSION: Although there is variation in the definition and management of AI-related adverse events in children amongst centres, there is also a good level of consensus on specific aspects that can lead to greater benchmarking of care.

How to manage puberty and prevent fertility disorders in men with CAH?

Gonadal dysfunction is an adverse outcome in patients with congenital adrenal hyperplasia (CAH), which may become apparent already during puberty. In males, gonadal dysfunction can be caused by primary gonadal failure due to testicular adrenal rest tumours (TART), and by secondary gonadal failure due to poor hormonal control.  Yearly evaluation for TART using ultrasonography is recommended from the start of puberty or even earlier when poor hormonal control is present. We recommend yearly evaluation of gonadal function by measuring LH, FSH, testosterone, and inhibin B. When TART is present, cryopreservation of semen should be considered as soon as possible.

Treatment of congenital adrenal hyperplasia in children aged 0-3 years: a retrospective multicenter analysis of salt supplementation, glucocorticoid and mineralocorticoid medication, growth and blood pressure.

Objectives: International guidelines recommend additional salt supplementation during infancy in classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. The influence of corticoid medication and growth has not been assessed. Aim: To investigate the current use of salt supplementation, fludrocortisone (FC) and hydrocortisone (HC) dosage as well as weight, height, BMI and blood pressure (BP) in CAH children aged 0-3 years. Methods: Retrospective multicentre analysis using data from the I-CAH registry. Salt-treated (ST) and non-salt-treated (NST) children were compared regarding FC and HC dosage, weight, height and BP at 0, 3, 6, 9, 12, 18, 24, 30, and 36 months. Results: We analysed 2483 visits of 331 patients born after year 2000 in 13 countries (male, n = 145) with 203 ST patients (61%). NST children had significantly higher FC dosages at 1.5-4.5 months and higher HC dosages until 1.5 months of age. No differences in weight, length and BP between subgroups were observed. Children of the whole cohort showed increased BMI-SDS during the study period and about half of the reported BP readings were >P95. Conclusion: In children treated with additional salt supplementation, FC and HC dosages are lower during the first months of life but without differences in weight, length and BP until 3 years of age compared to NST children. All children showed an increase in BMI-SDS and a high rate of BP readings >P95 until 3 years, indicating the start of weight gain and negative effects on blood pressure already in very early life.
