Gynecomastia and Its Management In Boys With Partial Androgen Insensitivity Syndrome.

INTRODUCTION: Partial androgen insensitivity syndrome (PAIS) is a rare condition that is reported to be commonly associated with gynecomastia in males. OBJECTIVES: To assess the management of gynecomastia in male PAIS. MATERIALS AND METHODS: Retrospective review of males with PAIS over the age of 10 years in the I-DSD registry. RESULTS: Of the 205 eligible cases, information was available for 57 from 13 centers. An androgen receptor gene variant was confirmed in 45 (79%) with a median age at first presentation of 1.0 year (range 0.1, 26.0). Of the 45 genetically confirmed cases, gynecomastia was present in 41 (91%) with a median age at the time of gynecomastia development of 13.5 years (11.0, 29.0). In the other 4 (9%) with no gynecomastia, the median age at last assessment was 15.7 years (10.6, 17.0). In 30 cases with information available, micropenis was present at the time of gynecomastia development in 23 (77%). Of the 35 with information available, 2 (6%) exhibited spontaneous resolution between the ages of 15 and 21 years and 25 (71%) had breast surgery at a median age of 15.7 years (14.0, 23.0). Of these 25, 9 (26%) had previously received medical therapy. The median clinician score of effectiveness for medical therapy was 3 (1, 8) compared to 10 (3, 10) for surgery (P < .0001). In 31 with information available, 13 (42%) had received psychology support. CONCLUSION: Gynecomastia is common in PAIS but not universal. Surgical management may be more effective than medical therapy, but there is a need for further standardized and systematic studies.

New liquid chromatography tandem mass spectrometry reference data for estradiol show mini-puberty in both sexes and typical pre-pubertal and pubertal patterns.

CONTEXT: Reliable estradiol (E2) reference intervals (RIs) are crucial in pediatric endocrinology. OBJECTIVES: This study aims to develop a sensitive ultra-performance liquid chromatographic tandem mass spectrometry (UPLC-MS/MS) method for E2 in serum, to establish graphically represented RI percentiles and annual RIs for both sexes, and to perform a systematic literature comparison. METHODS: First, a UPLC-MS/MS method for E2 was developed. Second, graphically represented RI percentiles and annual RIs covering 0-18 years were computed (cohort of healthy children [1181 girls and 543 boys]). Subsequently, RIs were compared with published data by systematic searches. RESULTS: Lower limit of quantification was 11 pmol/L, indicating high sensitivity. Estradiol first peaked during mini-puberty in both sexes (girls up to 192 pmol/L; boys up to 225 pmol/L). As could be expected, girls showed higher pubertal E2 (up to 638 pmol/L). However, boys' RIs (up to 259 pmol/L) overlapped considerably. We found 4 studies in the literature that also used LC-MS/MS to determine E2 and published RIs for the complete pediatric age range. Reference intervals varied considerably. Pre-pubertal and pubertal phases were present in all studies. Higher E2 during the time of mini-puberty in both sexes was documented in 3 studies including ours. CONCLUSIONS: Variability of RIs for E2 between studies illustrates the importance of laboratory-specific RIs despite using a LC-MS/MS reference method. In boys, the striking E2 peak during mini-puberty as well as high pubertal E2 without phenotypic estrogenization in regular male puberty indicates that the role of E2 in children and, especially in boys, requires better functional understanding.

The Endocrine Phenotype Induced by Pediatric Adrenocortical Tumors Is Age- and Sex-Dependent.

CONTEXT: Adrenocortical carcinomas are very rare malignancies in childhood associated with poor outcome in advanced disease. Most adrenocortical tumors (ACT) are functional, causing signs and symptoms of adrenal hormone excess. In most studies, endocrine manifestations were reported 4 to 6 months prior to diagnosis. OBJECTIVE: We sought to extend knowledge on endocrine manifestations with regard to age and sex to facilitate early diagnosis. METHODS: We retrospectively analyzed features of adrenal hormone excess in children and adolescents with ACT registered with the GPOH-MET studies between 1997 and 2022. Stage of puberty was defined as prepubertal in females < 8 years of age and males < 9 years. RESULTS: By December 2022, 155 patients (110 female, 45 male) with data on endocrine manifestations had been reported. Median age at ACT diagnosis was 4.2 years [0.1-17.8], median interval from first symptoms was 4.2 months [0-90.7]. In 63 girls of prepubertal age, the most frequently reported manifestations were pubarche (68.3%), clitoral hypertrophy (49.2%), and weight gain (31.7%); in 47 pubertal female patients, the most frequent manifestations were excessive pubic hair (46.8%), acne (36.2%), and hypertension (36.2%). Leading symptoms in 34 boys of prepubertal age were pubarche (55.9%), penile growth (47.1%), and acne (32.4%), while in 11 pubertal male patients, leading symptoms were weight gain (45.5%), hypertension (36.4%), excessive pubic hair (27.3%), and cushingoid appearance (27.3%). In pubertal patients, symptoms of androgen excess were mainly unrecognized as part of pubertal development, while symptoms of Cushing syndrome were more frequently apparent. CONCLUSION: The endocrine phenotype induced by pediatric ACT is age- and sex-dependent.

Predictors of surgical complications in boys with hypospadias: data from an internationa registry.

Background: Complications are frequently reported after hypospadias repair and there is a need to understand the factors that influence their occurrence. Methods: Data from boys with hypospadias born between 2000 and 2020 were obtained from the International Disorders of Sex Development (I-DSD) Registry. Logistic regressions, fisher's exact tests and spearman's correlation tests were performed on the data to assess associations between clinical factors and complication rates. Results: Of the 551 eligible boys, data were available on 160 (29%). Within the cohort, the median (range) External Masculinization Score (EMS) was 6 (2, 9). All presented with one or more additional genital malformation and 61 (38%) presented with additional extragenital malformations. Disorders of androgen action, androgen synthesis and gonadal development were diagnosed in 28 (18%), 22 (14%) and 9 (6%) boys, respectively. The remaining 101 (62%) patients were diagnosed as having non-specific 46,XY Disorders of Sex Development. Eighty (50%) boys had evidence of abnormal biochemistry, and gene variants were identified in 42 (26%). Median age at first hypospadias surgery was 2 years (0, 9), and median length of follow-up was 5 years (0, 17). Postsurgical complications were noted in 102 (64%) boys. There were no significant associations with postsurgical complications. Conclusions: Boys with proximal hypospadias in the I-DSD Registry have high rates of additional comorbidities and a high risk of postoperative complications. No clinical factors were significantly associated with complication rates. High complication rates with no observable cause suggest the involvement of other factors which need investigation.

Locally Advanced Adrenocortical Carcinoma in Children and Adolescents-Enigmatic and Challenging Cases.

BACKGROUND: Locally advanced tumors account for approximately 50% of children and adolescents with adrenocortical carcinoma (ACC), and of these, up to 50% relapse. We explored the five-item microscopic score and the pS-GRAS score for guiding management. METHODS: Data from children and adolescents with COG stage II and III ACC registered in the MET studies were included. The five-item and pS-GRAS score were retrospectively calculated. RESULTS: By December 2021, 55 patients with stage II and III (stage II n = 18, stage III n = 37) had been reported. Median age was 4.3 years [0.1-17.8], median duration of follow-up 6.0 years [0-16.7]. 3-year event-free survival (EFS) rate was 76.5% and 49.8% (p = 0.088), respectively. In stage II tumors, neither the five-item score (p = 0.872) nor pS-GRAS grouping (p = 0.218) had any effect as prognostic factors. In stage III patients, EFS was impaired in tumors with unfavorable histology according to the five-item score (100% vs. 30.8%, p = 0.018). No difference was observed for pS-GRAS groups (p = 0.798). CONCLUSIONS: In patients with COG stage III, but not stage II, the five-item score affected EFS. Further studies are needed to identify patients at risk in COG stage II.

Pilot study shows suppression of mineralocorticoid precursors under high-dose glucocorticoid therapy in pediatric acute lymphoblastic leukemia.

Glucocorticoids represent a key element in the treatment of pediatric acute lymphoblastic leukemia (ALL) and lead to adrenal suppression. We aimed to assess the differential response profile of adrenal steroids in children with ALL during BFM (Berlin-Frankfurt-Münster) induction treatment. Therefore, we performed liquid chromatography tandem-mass spectrometry (LC-MS/MS)-based steroid profiling of up to seven consecutive leftover morning serum samples derived from 11 patients (pts) with ALL before (day 0) and during induction therapy at days 1-5, 6-12, 13-26, 27-29, 30-35 and 36-40. 17-hydroxyprogesterone (17OHP), 11-deoxycortisol (11S), cortisol, 11-deoxycorticosterone (DOC), corticosterone and aldosterone were determined in parallel. Subsequently, steroid concentrations were normalized by multiples of median (MOM) to adequately consider pediatric age- and sex-specific reference ranges. MOM-cortisol and its precursors MOM-11S and MOM-17OHP were significantly suppressed by glucocorticoid treatment until day 29 (P < 8.06 × 10-10, P < 5.102 × 10-5, P < 0.0076, respectively). Cortisol recovered in one of four pts at days 27-29 and in two of five pts at days 36-40. Among the mineralocorticoids, corticosterone was significantly suppressed (P < 3.115 × 10-6). Aldosterone and DOC showed no significant changes when comparing day 0 to the treatment time points. However, two ALL patients with ICU treatment due to the sepsis showed significantly lower MOM-DOC (P = 0.006436) during that time and almost always the lowest aldosterone compared to all other time points. Suppression of mineralocorticoid precursors under high-dose glucocorticoid therapy suggests a functional cross talk of central glucocorticoid regulation and adrenal mineralocorticoid synthesis. Our data should stimulate prospective investigation to assess potential clinical relevance.

Formin-mediated nuclear actin at androgen receptors promotes transcription.

Steroid hormone receptors are ligand-binding transcription factors essential for mammalian physiology. The androgen receptor (AR) binds androgens mediating gene expression for sexual, somatic and behavioural functions, and is involved in various conditions including androgen insensitivity syndrome and prostate cancer1. Here we identified functional mutations in the formin and actin nucleator DAAM2 in patients with androgen insensitivity syndrome. DAAM2 was enriched in the nucleus, where its localization correlated with that of the AR to form actin-dependent transcriptional droplets in response to dihydrotestosterone. DAAM2 AR droplets ranged from 0.02 to 0.06 µm3 in size and associated with active RNA polymerase II. DAAM2 polymerized actin directly at the AR to promote droplet coalescence in a highly dynamic manner, and nuclear actin polymerization is required for prostate-specific antigen expression in cancer cells. Our data uncover signal-regulated nuclear actin assembly at a steroid hormone receptor necessary for transcription.

Age at menarche relates to depression in adolescent girls: Comparing a clinical sample to the general pediatric population.

CONTEXT: The timing of puberty, physical features of pubertal development, and hormones are closely intertwined but may also individually contribute to the risk for depression and depression severity. Additionally, their effects on mood may depend on depression severity, but previously this has only been studied in mostly subclinical depression. METHODS: In 184 girls from a single psychiatric hospital with significant depressive symptoms (Beck Depression Inventory-II score > 13), the relationship between depression severity and age at menarche (AAM), pubertal status, and gonadal/adrenal hormones (estradiol, progesterone, DHEA-S, androstenedione, testosterone, dihydrotestosterone) was investigated. Moreover, AAM in depressed girls was compared to that from a representative sample of German adolescents without a psychiatric disorder (N = 1674). Androgen levels were compared to those of age- and sex-matched controls (N = 59). RESULTS: AAM but not pubertal stage or biochemical parameters related to depression. Girls with AAM at the lower normative range of pubertal development were 61 % more likely to develop depression and scored 4.9 points higher on the depression scale than girls experiencing menarche at the population average. Androstenedione levels were increased in the psychiatric sample, but neither androgen nor gonadal hormone levels were associated with depression severity. LIMITATIONS: The study is cross-sectional. CONCLUSIONS: These observations confirm previous studies in mostly subclinical depression and highlight the importance of AAM for adolescent depression. Thus, AAM could be considered a prognostic factor for a clinical risk score assessing the probability of adolescent depression. Moreover, these findings suggest fostering efforts that address risk factors that contribute to an earlier AAM.

Metabolic effects of estradiol versus testosterone in complete androgen insensitivity syndrome.

PURPOSE: To study differences in metabolic outcomes between testosterone and estradiol replacement in probands with complete androgen insensitivity syndrome (CAIS). METHODS: In this multicentre, double-blind, randomized crossover trial, 26 women with CAIS were included of whom 17 completed the study. After a two-months run in phase with estradiol, probands either received transdermal estradiol followed by crossover to transdermal testosterone or vice versa. After six months, differences in lipids, fasting glucose, insulin, hematocrit, liver parameters and blood pressure between the treatment phases were investigated. RESULTS: Linear mixed models adjusted for period and sequence did not reveal major group differences according to treatment for the investigated outcomes. In each treatment group, there were however significant uniform changes in BMI and cholesterol. BMI increased significantly, following six months of estradiol ( + 2.7%; p = 0.036) as well as testosterone treatment ( + 2.8%; p = 0.036). There was also a significant increase in total ( + 10.4%; p = 0.001) and LDL-cholesterol ( + 29.2%; p = 0.049) and a decrease in HDL-cholesterol (-15.8%; p < 0.001) following six months of estradiol as well as six months of testosterone treatment (total cholesterol: + 14.6%; p = 0.008; LDL-cholesterol: + 39.1%; p = 0.005, HDL-cholesterol: -15.8%; p = 0.004). Other parameters remained unchanged. CONCLUSION: Transdermal estradiol as well as testosterone treatment in women with CAIS results in worsening in lipid profiles. Given the relatively small sample size, subtle group differences in other metabolic parameters may have remained undetected.

Genomic variants reducing expression of two endocytic receptors in 46,XY differences of sex development.

Transporter-dependent steroid hormone uptake into target cells was demonstrated in genetically engineered mice and fruit flies. We hypothesized that mutations in such transporters may cause differences in sex development (DSD) in humans. Exome sequencing was performed in 16 genetically unsolved cases of 46,XY DSD selected from an anonymized collection of 708 lines of genital fibroblasts (GF) that were taken from individuals with incomplete virilization. Selection criteria were based on available biochemical characterization of GF compatible with reduced androgen uptake. Two unrelated individuals were identified with mutations in LDL receptor-related protein 2 (LRP2), a gene previously associated with partial sex steroid insensitivity in mice. Like Lrp2-/- mice, affected individuals had non-descended testes. Western blots on GF confirmed reduced LRP2 expression, and endocytosis of sex hormone-binding globulin was reduced. In three unrelated individuals, two with undescended testes, mutations in another endocytic receptor gene, limb development membrane protein 1 like (LMBR1L), were detected. Two of these individuals had mutations affecting the same codon. In a transfected cell model, mutated LMBR1L showed reduced cell surface expression. Our findings suggest that endocytic androgen uptake in complex with sex hormone-binding globulin is relevant in human. LMBR1L may play a similar role in androgen uptake.

Outcome for Pediatric Adreno-Cortical Tumors Is Best Predicted by the COG Stage and Five-Item Microscopic Score-Report from the German MET Studies.

Background: Adrenocortical tumors (ACTs) encompassing the adrenocortical adenoma (ACA), carcinoma (ACC), and tumors of undetermined malignant potential (ACx) are rare endocrine neoplasms with a poor prognosis. We report on pediatric ACT patients registered with the Malignant Endocrine Tumor studies and explore the EXPeRT recommendations for management. Patients: Data from the ACT patients (<18 years) were analyzed. For the risk prediction, the patients were retrospectively assigned to the COG stages and the five-item score. Results: By December 2021, 161 patients with ACT (ACA n = 51, ACx n = 19, and ACC n = 91) had been reported (the median age at the diagnosis was 4.3 years with a range of 0.1−17.8), with lymph node and distant metastases in 10.7% and 18.9% of the patients with ACC/ACx. The mean follow-up was 4.5 years (with a range of 0−16.7). The three-year overall (OS) and event-free survival (EFS) rates were 65.5% and 50.6%. In the univariate analyses, the OS was impaired for patients aged ≥ 4 years (p = 0.001) with the initial biopsy (p = 0.016), tumor spillage (p = 0.028), incomplete tumor resection (p < 0.001), unfavorable histology (p = 0.047), and COG stages III/IV (p = 0.002). Multivariate analysis revealed COG stages III/IV and an unfavorable five-item score as independent negative prognostic factors for the EFS and OS. Conclusions: Age defines the clinical presentation and prognosis in pediatric ACTs. The outcome is best predicted by the COG stage and five-item score.

New Insights Into Extended Steroid Hormone Profiles in Transwomen in a Multi-Center Setting in Germany.

BACKGROUND: Little information is available on steroid hormone profiles in transwomen on the day of gender affirming surgery (GAS) after gender affirming hormone therapy (GAHT). AIM: We compared extended serum steroid hormone profiles of 77 transwomen with 3 different treatment regimens in order to get more insight on how GAHT changes the hormone system. METHODS: Samples were obtained from 3 independent clinics. Individuals in clinic A (n = 13) and B (n = 51) discontinued GAHT 4-6 weeks and 2 weeks before GAS, individuals in clinic C (n = 13) continued treatment. Testicular tissue, blood samples and questionnaires on age, weight, height, and medication use were received from each patient. Steroid hormones were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS), 6 sex hormones were determined by immunofluorometric assays, and ELISA. Spermatogenesis was scored using the Bergman/Kliesch score. OUTCOMES: Participants were not different with regard to age, BMI, treatment duration, and dosage. Feminized blood serum levels with low LH, low FSH and low testosterone, however, were achieved in persons taking GAHT until GAS. Significantly reduced cortisone levels were seen after stopping GAHT before GAS. RESULTS: GAHT had marked effects on the sex-steroid profile in each person. Factor analysis provided a model explaining 78% of the variance and interdependency of sex steroid levels. Stopping treatment was inversely associated with intactness of the corticosteroid-axis with adrenal steroidogenesis as well as it was inversely associated with pituitary-gonadal hormone production. CLINICAL IMPLICATIONS: Transwomen generally did not have elevated cortisone levels but differed significantly depending on and when GAHT was stopped. STRENGTHS & LIMITATIONS: This is the first study examining the steroid hormone profiles of transgender persons on the day of GAS in a multi-center setting. Additional studies (including follow ups before and after GAS and stress questionnaires) will be necessary to assess these conflicting results about the possible psychological impact on persons undergoing GAS to improve care. CONCLUSION: Concerning feminized blood serum levels, continued GAHT seems the better alternative, however stopping treatment 4-6 weeks prior to surgery was associated with reduced cortisone levels.

Gonadectomy in conditions affecting sex development: a registry-based cohort study.

OBJECTIVES: To determine trends in clinical practice for individuals with DSD requiring gonadectomy. DESIGN: Retrospective cohort study. METHODS: Information regarding age at gonadectomy according to diagnosis; reported sex; time of presentation to specialist centre; and location of centre from cases reported to the International DSD Registry and who were over 16 years old in January 2019. RESULTS: Data regarding gonadectomy were available in 668 (88%) individuals from 44 centres. Of these, 248 (37%) (median age (range) 24 (17, 75) years) were male and 420 (63%) (median age (range) 26 (16, 86) years) were female. Gonadectomy was reported from 36 centres in 351/668 cases (53%). Females were more likely to undergo gonadectomy (n = 311, P < 0.0001). The indication for gonadectomy was reported in 268 (76%). The most common indication was mitigation of tumour risk in 172 (64%). Variations in the practice of gonadectomy were observed; of the 351 cases from 36 centres, 17 (5%) at 9 centres had undergone gonadectomy before their first presentation to the specialist centre. Median age at gonadectomy of cases from high-income countries and low-/middle-income countries (LMIC) was 13.0 years (0.1, 68) years and 16.5 years (1, 28), respectively (P < 0.0001) with the likelihood of long-term retention of gonads being higher in LMIC countries. CONCLUSIONS: The likelihood of gonadectomy depends on the underlying diagnosis, sex of rearing and the geographical setting. Clinical benchmarks, which can be studied across all forms of DSD will allow a better understanding of the variation in the practice of gonadectomy.

Transition from gynaecomastia to lipomastia in pubertal boys.

OBJECTIVE: Gynaecomastia is frequent in pubertal boys and is regarded as a self-limiting abnormality. However, longitudinal studies proving this hypothesis are scarce. DESIGN: Longitudinal follow-up study (median 2.4, range 1.0-4.8 years). METHODS: The regression of breast diameter was analysed in 31 pubertal boys aged 11.7-16.1 (median 13.2) years with gynaecomastia. Furthermore, weight changes (as BMI-SDS) and pubertal stage, oestradiol [E2], oestriol, oestrone, androstenedione, testosterone [T], dihydrotestosterone, gonadotropins, IGF-1, and IGFBP-3 serum concentrations determined at first clinical presentation were related to breast diameter regression determined by palpation and disappearance of breast glandular tissue in ultrasound in follow-up to identify possible predictors of breast regression. RESULTS: During the observation period, the breast diameter decreased (in median -1 (interquartile range [IQR] -5 to +1) cm). At follow-up, 6% of boys had no breast enlargement any more, and 65% developed lipomastia. Gynaecomastia was still present in 29%. None of the analysed hormones was related significantly to breast diameter regression or disappearance of breast glandular tissue. In multiple linear regression analyses adjusted for observational period, as well as age and BMI-SDS at first presentation, changes in BMI-SDS (ß-coefficient 6.0 ± 2.3, p = .015) but not the E2/T ratio or any other hormone determined at baseline was related to changes in breast diameter. CONCLUSIONS: Breast diameter regression seems not to be predictable by a hormone profile in pubertal boys with gynaecomastia. In pubertal boys presenting with gynaecomastia, conversion to lipomastia of smaller volume is common. The reduction of weight status was the best predictor of breast diameter regression.

Sex Hormone Profile in Pubertal Boys With Gynecomastia and Pseudogynecomastia.

CONTENT: Gynecomastia (defined by proliferation of glandular elements) and pseudogynecomastia (defined by adipose tissue) are frequent in pubertal boys. An association with sex hormones and the growth hormone axis has been discussed. OBJECTIVE: The objective of this work is to compare sex hormones, insulin-like growth factor 1 (IGF-1), and insulin-like growth factor binding protein 3 (IGFBP-3) between boys with gynecomastia and pseudogynecomastia (separation by ultrasound). DESIGN: An observational study was performed. SETTING: The setting of this study was an outpatient clinic. PARTICIPANTS: A total of 124 pubertal boys (mean age 14 ±â€…2 years) with breast enlargement and 84 healthy boys (mean age 14 ±â€…2 years) without breast enlargement participated in this study. INTERVENTIONS: No interventions were performed. MAIN OUTCOME MEASURES: Measurements were taken for sex hormones (progesterone, estradiol [E2], estriol, estrone, androstendione, testosterone [T], dihydrotestosterone) measured by liquid chromatography-tandem mass spectrometry, as well as gonadotropins, prolactin, IGF-1, and IGFBP-3. RESULTS: Eighty-six boys suffered from gynecomastia and 38 from pseudogynecomastia. In boys with gynecomastia, the E2/T ratio (median 22, interquartile range [IQR] 8-75) was significantly (P < .05) higher compared to boys with pseudogynecomastia (median 12, IQR 5-21) or healthy controls without breast enlargement (median 18, IQR 6-44) even after adjustment for testes volume. T concentrations were significantly (P < .05) lower in boys with gynecomastia (median 1.8, IQR 0.7-4.2 nM/L) compared to boys with pseudogynecomastia (median 4.3, IQR 1.4-6.9 nM/L) or healthy controls without breast enlargement (median 3.1, IQR 0.6-7.6 nM/L). Boys with gynecomastia did not differ from boys with pseudogynecomastia according to other sex hormones, prolactin, IGF-1, or IGFBP-3 concentrations. CONCLUSIONS: True gynecomastia is characterized by a relative T deficiency to E2 concentrations in contrast to pseudogynecomastia.

Clinical but Not Histological Outcomes in Males With 45,X/46,XY Mosaicism Vary Depending on Reason for Diagnosis.

CONTEXT: Larger studies on outcomes in males with 45,X/46,XY mosaicism are rare. OBJECTIVE: To compare health outcomes in males with 45,X/46,XY diagnosed as a result of either genital abnormalities at birth or nongenital reasons later in life. DESIGN: A retrospective, multicenter study. SETTING: Sixteen tertiary centers. PATIENTS OR OTHER PARTICIPANTS: Sixty-three males older than 13 years with 45,X/46,XY mosaicism. MAIN OUTCOME MEASURES: Health outcomes, such as genital phenotype, gonadal function, growth, comorbidities, fertility, and gonadal histology, including risk of neoplasia. RESULTS: Thirty-five patients were in the genital group and 28 in the nongenital. Eighty percent of all patients experienced spontaneous pubertal onset, significantly more in the nongenital group (P = 0.023). Patients were significantly shorter in the genital group with median adult heights of 156.7 cm and 164.5 cm, respectively (P = 0.016). Twenty-seven percent of patients received recombinant human GH. Forty-four patients had gonadal histology evaluated. Germ cells were detected in 42%. Neoplasia in situ was found in five patients. Twenty-five percent had focal spermatogenesis, and another 25.0% had arrested spermatogenesis. Fourteen out of 17 (82%) with semen analyses were azoospermic; three had motile sperm. CONCLUSION: Patients diagnosed as a result of genital abnormalities have poorer health outcomes than those diagnosed as a result of nongenital reasons. Most patients, however, have relatively good endocrine gonadal function, but most are also short statured. Patients have a risk of gonadal neoplasia, and most are azoospermic, but almost one-half of patients has germ cells present histologically and up to one-quarter has focal spermatogenesis, providing hope for fertility treatment options.

Management of Gonads in Adults with Androgen Insensitivity: An International Survey.

BACKGROUND: Complete and partial androgen insensitivity syndrome (CAIS, PAIS) are associated with an increased risk of gonadal germ cell cancer (GGCC). Recent guidelines recommend gonadectomy in women with CAIS in late adolescence. Nevertheless, many adult women prefer to retain their gonads. AIMS: This study aims to explore attitudes towards gonadectomy in AIS in centres around the world, estimate the proportion of adults with retained gonads and/or who developed GGCC, and explore reasons for declining gonadectomy. METHODS: A survey was performed among health care professionals who use the International DSD Registry (I-DSD). RESULTS: Data were provided from 22 centres in 16 countries on 166 women (CAIS) and 26 men (PAIS). In CAIS, gonadectomy was recommended in early adulthood in 67% of centres; 19/166 (11.4%) women refused gonadectomy. Among 142 women who had gonadectomy, evidence of germ cell neoplasm in situ (GCNIS), the precursor of GGCC, was reported in 2 (1.4%) out of 8 from whom pathology results were formally provided. Nine out of 26 men with PAIS (34.6%) had retained gonads; 11% of centres recommended routine gonadectomy in PAIS. CONCLUSION: Although development of GGCC seems rare, gonadectomy after puberty is broadly recommended in CAIS; in PAIS this is more variable. Overall, our data reflect the need for evidence-based guidelines regarding prophylactic gonadectomy in AIS.

Oestrogen versus androgen in hormone-replacement therapy for complete androgen insensitivity syndrome: a multicentre, randomised, double-dummy, double-blind crossover trial.

BACKGROUND: Women with complete androgen insensitivity syndrome (CAIS) after gonadectomy have complained about reduced psychological wellbeing and sexual satisfaction. The aim of this study was to compare the effectiveness of hormone-replacement therapy with either androgen or oestrogen in women with 46,XY karyotype and CAIS after gonadectomy. METHODS: This national, multicentre, double-blind, randomised crossover trial was performed at three university medical centres and three specialised treatment institutions in Germany. Eligible participants were women aged 18-54 years with 46,XY karyotype, genetically diagnosed CAIS, and removed gonads. Participants were randomly assigned (14:12) by a central computer-based minimisation method to either oestradiol 1·5 mg/day for 6 months followed by crossover to testosterone 50 mg/day for 6 months (sequence A) or to testosterone 50 mg/day for 6 months followed by crossover to oestradiol 1·5 mg/day for 6 months (sequence B). Participants also received oestradiol or testosterone dummy to avoid identification of the active substance. All participants received oestradiol 1·5 mg/day during a 2 months' run-in phase. The primary outcome was mental health-related quality of life, as measured with the standardised German version of the SF-36 questionnaire. Secondary outcomes were psychological wellbeing, as measured with the Brief Symptom Inventory (BSI), sexual function, as measured with the Female Sexual Function Index (FSFI), and somatic effects, such as signs of virilisation and effects on metabolic blood values. The primary analysis included all patients who were available at least until visit 5, even if protocol violations occurred. The safety analysis included all patients who received at least oestradiol during the run-in phase. This trial is registered with the German Clinical Trials Register, number DRKS00003136, and with the European Clinical Trials Database, number 2010-021790-37. FINDINGS: We enrolled 26 patients into the study, with the first patient enrolled on Nov 7, 2011, and the last patient leaving the study on Jan 23, 2016. 14 patients were assigned to sequence A and 12 were assigned to sequence B. Ten participants were withdrawn from the study, two of whom attended at least five visits and so could be included in the primary analysis. Mental health-related quality of life did not differ between treatment groups (linear mixed model, p=0·794), nor did BSI scores for psychological wellbeing (global severity index, p=0·638; positive symptom distress index, p=0·378; positive symptom total, p=0·570). For the FSFI, testosterone was superior to oestradiol only in improving sexual desire (linear mixed model, p=0·018). No virilisation was observed, and gonadotrophin concentrations remained stable in both treatment groups. Oestradiol and testosterone concentrations changed substantially during the study in both treatment groups. 28 adverse events were reported for patients receiving oestradiol (23 grade 1 and five grade 2), and 38 adverse events were reported for patients receiving testosterone (34 grade 1, three grade 2, and one grade 3). One serious adverse event (fibrous mastopathy) and 20 adverse events (16 grade 1 and four grade 2) were reported during the run-in phase, and 12 adverse events during follow-up (nine grade 1 and three grade 2). INTERPRETATION: Testosterone was well tolerated and as safe as oestrogen for hormone-replacement therapy. Testosterone can be an alternative hormone substitution in CAIS, especially for woment with reduced sexual functioning. FUNDING: German Federal Ministry of Education and Research.

Epigenetic Repression of Androgen Receptor Transcription in Mutation-Negative Androgen Insensitivity Syndrome (AIS Type II).

Context: Inactivating mutations within the AR gene are present in only ~40% of individuals with clinically and hormonally diagnosed androgen insensitivity syndrome (AIS). Previous studies revealed the existence of an AR gene mutation-negative group of patients with AIS who have compromised androgen receptor (AR) function (AIS type II). Objective: To investigate whether AIS type II can be due to epigenetic repression of AR transcription. Design: Quantification of AR mRNA and AR proximal promoter CpG methylation levels in genital skin-derived fibroblasts (GFs) derived from patients with AIS type II and control individuals. Setting: University hospital endocrine research laboratory. Patients: GFs from control individuals (n = 11) and patients with AIS type II (n = 14). Main Outcome Measure(s): Measurement of AR mRNA and AR promoter CpG methylation as well as activity of AR proximal promoter in vitro. Results: Fifty-seven percent of individuals with AIS type II (n = 8) showed a reduced AR mRNA expression in their GFs. A significant inverse correlation was shown between AR mRNA abundance and methylation at two consecutive CpGs within the proximal AR promoter. Methylation of a 158-bp-long region containing these CpGs was sufficient to severely reduce reporter gene expression. This region was bound by the runt related transcription factor 1 (RUNX1). Ectopic expression of RUNX1 in HEK293T cells was able to inhibit reporter gene expression through this region. Conclusions: Aberrant CpGs methylation within the proximal AR promoter plays an important role in the control of AR gene expression and may result in AIS type II. We suggest that transcriptional modifiers, such as RUNX1, could play roles therein offering new perspectives for understanding androgen-mediated endocrine diseases.

Multiples of Median-Transformed, Normalized Reference Ranges of Steroid Profiling Data Independent of Age, Sex, and Units.

BACKGROUND/AIMS: The high complexity of pediatric reference ranges across age, sex, and units impairs clinical application and comparability of steroid hormone data, e.g., in congenital adrenal hyperplasia (CAH). We developed a multiples-of-median (MoM) normalization tool to overcome this major drawback in pediatric endocrinology. METHODS: Liquid chromatography tandem mass spectrometry data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to > 16 years) from 2 previous datasets were MoM transformed across age and sex. Twenty-three genetically proven CAH patients were included (21-hydroxylase deficiency [21OHD], n = 19; 11ß-hydroxylase deficiency [11OHD], n = 4). MoM cutoffs for single steroids predicting 21OHD and 11OHD were computed and validated through new, independent patients (21OHD, n = 8; adrenal cortical carcinoma, n = 6; obesity, n = 40). RESULTS: 21OHD and 11OHD patients showed disease-typical, easily recognizable MoM patterns independent of age, sex, and concentration units. Two single-steroid cutoffs indicated 21OHD: 3.87 MoM for 17-hydroxyprogesterone (100% sensitivity and 98.83% specificity) and 12.28 MoM for 21-deoxycortisol (94.74% sensitivity and 100% specificity). A cutoff of 13.18 MoM for 11-deoxycortisol indicated 11OHD (100% sensitivity and 100% specificity). CONCLUSIONS: Age- and sex-independent MoMs are straightforward for a clinically relevant display of multi-steroid patterns. In addition, defined single-steroid MoMs can serve alone as predictors of 21OHD and 11OHD. Finally, MoM transformation offers substantial enhancement of routine and scientific steroid hormone data exchange due to improved comparability.
