design, methodology, recruitment, data quality and study population

Background dsd-LIFE is a comprehensive cross-sectional clinical outcome study of individuals with disorders/differences of sex development (DSD). This study focuses on various rare genetic conditions characterized by impaired gonadal or adrenal functionality. Methods/Design The study aims to assess quality of life (QoL) as a measure of psychosocial adaptation, psychosexual and mental health aspects as major outcomes. Health status and functioning, medical and surgical therapies, participants’ views on health care, psychological and social support, sociodemographic factors and their interrelations will be investigated as factors associated with the outcomes. In addition, ethical considerations in the field of DSD are addressed and previous experiences with health care were gathered. One thousand and forty participants with different DSD conditions were recruited by 14 study centres in 6 European countries (France, Germany, the Netherlands, Poland, Sweden and the United Kingdom) from February 2014 until September 2015. The conditions included were: Turner syndrome (n = 301); 45,X0/46,XY conditions (n = 45); Klinefelter syndrome (n = 218); 47,XYY (n = 1); 46,XY gonadal dysgenesis/ovotestes (n = 63); complete androgen insensitivity (CAIS) (n = 71); partial androgen insensitivity (PAIS) (n = 35) and androgen synthesis disorders (n = 20); severe hypospadias (n = 25); other or non-classified 46,XY DSD (n = 8); 46,XX congenital adrenal hyperplasia (CAH) (n = 226); 46,XX gonadal dysgenesis/ovotestis (n = 21); and 46,XX in males (n = 6). For an add-on study, 121 46,XY male-assigned individuals with CAH due to 21-hydroxylase deficiency were recruited. Mean age of participants’ was 32.4 (+/− 13.6 years). Discussion Participation was high in conditions not commonly described as DSD, such as Turner and Klinefelter syndromes or CAH. Recruitment of individuals with XY DSD conditions proved to be more difficult. The data collection of PROs resulted in high data quality. Within medical and physical examination data, more missings and/or inaccurate data were found than expected. The European dsd-LIFE study recruited and evaluated the largest cross-sectional sample of individuals with different conditions classified under the term DSD. The data from this large sample will provide a sufficient basis for evidence-based recommendations for improvement of clinical care of individuals affected by a DSD condition.

Gonadotropin administration to mimic mini-puberty in hypogonadotropic males: pump or injections?

Objective: Newborns with congenital hypogonadotropic hypogonadism (CHH) have an impaired postnatal activation of the gonadotropic axis. Substitutive therapy with recombinant gonadotropins can be proposed to mimic physiological male mini-puberty during the first months of life. The aim of this study was to co mpare the clinical and biological efficacy of two treatment modalities of gonadotropins administration during mini-puberty in CHH neonates. Design: Multicenter retrospective analytical epidemiological study comparing two treatments, pump vs injection, between 2004 and 2019. Methods: Clinical (penile size, testis size, testicular descent) and biological parameters (serum concentrations of testosterone, anti-Müllerian hormone (AMH) and Inhibin B) were compared between the two groups by multivariate analyses. Results: Thirty-five patients were included. A significantly higher incre ase in penile length and testosterone level was observed in the injection group compared to the pump group (+0.16 ± 0.02 mm vs +0.10 ± 0.02 mm per day, P = 0.002; and +0.04 ± 0.007 ng/mL vs +0.01 ± 0.008 ng/mL per day, P = 0.001). In both groups, significant increases in penile length and width, testosterone, AMH, and Inhibin B levels were observed, as well as improved testicular descent (odds ratio of not being in a scrotal position at the end of treatment = 0.97 (0.96; 0.99)). Conclusions: Early postnatal administration of recombinant gonadotropins in CHH boys is effective in stimulating penile growth, Sertoli cell proliferati on, and testicular descent, with both treatment modalities

Experience in Optimising Fertility Outcomes in Men with Congenital Adrenal Hyperplasia due to 21 Hydroxylase Deficiency.

OBJECTIVE: Men with congenital adrenal hyperplasia (CAH) have impaired fertility. We aimed to assess fertility outcomes and the importance of hypogonadotropic hypogonadism, testicular failure and the presence of testicular adrenal rest tumours (TART). DESIGN: Retrospective analysis of men attending an adult CAH clinic in a tertiary centre. PATIENTS: Fifty men with CAH due to 21 hydroxylase deficiency were identified of whom 35 were salt-wasting and 15 were non-salt-wasting. MEASUREMENTS: Review of fertility history and parameters including luteinising hormone (LH), follicle stimulating hormone (FSH), androstenedione, 17-hydroxyprogesterone (17-OHP), semen analysis and the presence of testicular adrenal rest tissue (TART) on ultrasound. RESULTS: TART were detected by ultrasound in 21 (47%) and their presence was associated with an elevated FSH (p=0.01). Severe oligospermia was present in 11/23 (48%), and this was associated with an elevated FSH (p=0.02), suppressed LH (p5 x 10(6) per ml. Of those that desired fertility, 10/17 (59%) required treatment intensification, and 4 underwent in vitro fertilisation. Intensification resulted in a rise in median LH (0.6 to 4.3 IU/L; p=0.01). Live birth rate was 15/17 (88%) with a median (range) time to conception of 8(0-38) months. CONCLUSIONS: Suppressed LH is a marker for subfertility and is often reversible. Testicular failure is closely associated with TART formation. If TART are detected, sperm cryopreservation should be offered given the risk of progression to irreversible testicular failure. Male fertility in CAH can be improved by intensified treatment and assisted reproductive technology. This article is protected by copyright. All rights reserved

Quality of Life in Men With Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is a disorder of adrenal steroid biosynthesis, leading to hypocortisolism, hypoaldosteronism, and hyperandrogenism. Impaired quality of life (QoL) has been demonstrated in women with CAH, but data on men with CAH are scarce. We hypothesized that disease severity and poor treatment control are inversely associated with QoL. In this study, 109 men (16-68 years) with 21OHD were included. The WHOQOL-BREF questionnaire was used to measure self-reported QoL domain scores on a 0-100 scale, where higher scores reflect better QoL. QoL domain scores were compared to published data on healthy and chronically ill reference populations from France, Germany, the Netherlands, and the United Kingdom. Differences in QoL scores among groups of disease severity and treatment control were tested within the study population. Overall, the men with CAH in this study appeared to rate their QoL as good. Median domain scores were 78.6 (IQR: 67.9-85.7) for physical health, 79.2 (IQR: 66.7-87.5) for psychological health, 75.0 (IQR: 58.3-83.3) for social relationships, and 81.3 (IQR: 71.9-90.6) for environment. In general, these scores were similar to WHOQOL-BREF domain scores in healthy references and higher compared to chronically ill reference populations. The domain scores did not differ among genotype groups, but patients with undertreatment or increased 17-hydroxyprogestrone concentrations scored higher on several QoL domains (p<0.05). Patients treated with dexamethasone or prednisone scored higher on the physical health, psychological health, and social relationships domains, but not on the environmental domain. In conclusion, QoL domain scores appeared to be comparable to healthy reference populations and higher compared to patients with a chronic illness. QoL was not influenced by genotype, but undertreatment and use of dexamethasone or prednisone were associated with higher QoL

Health status in 1040 adults with disorders of sex development (DSD): a European multicenter study

Objective: The knowledge about health status in adults with disorder of sex development (DSD) is scarce. Design and methods: A cross-sectional observational study in 14 European tertiary centers recruited 1040 participants (717 females, 311 males, 12 others) with DSD. Mean age was 32.4 +/- 13.6 year (range 16-75). The cohort was divided into: Turner (n = 301), Klinefelter (n = 224), XY-DSD (n = 222), XX-DSD (excluding congenital adrenal hyperplasia (CAH) and 46,XX males) (n = 21), 46,XX-CAH (n = 226) and 45,X/46,XY (n = 45). Perceived and objective health statuses were measured and compared to European control data. Results: In DSD, fair to very good general health was reported by 91.4% and only 8.6% reported (very) bad general health (controls 94.0% and 6.0%, P<0.0001) Longstanding health issues other than DSD and feeling limited in daily life were reported in 51.0% and 38.6%, respectively (controls 24.5% and 13.8%, P< 0.0001 both). Any disorder except DSD was present in 84.3% (controls 24.6%, P< 0.0001). Males reported worse health than females In the subgroup analysis, Klinefelter and 46,XX-DSD patients reported bad general health in 15.7% and 16.7%, respectively (Turner 3.2% and CAH 7.4%). Comorbidities were prevalent in all DSD subgroups but Klinefelter and Turner were most affected. Early diagnosis of DSD and a healthy lifestyle were associated with less comorbidities. Conclusions: Overall, general health appeared to be good but a number of medical problems were reported, especially in Klinefelter and Turner. Early diagnosis of DSD and a healthy lifestyle seemed to be important. Lifelong follow-up at specialized centers is necessary

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 mortal ity, 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 clinic al study centres in 6 European countries which participated in the Europ ean dsd-LIFE study. Male normative data from a healthy and a psychiatric reference population were used for comparison. The validated World Health Organization (WHO) Q OL (WHOQOL)-BREF questionnaire was used to investigate five main domains of quali ty of life (WHOQOL): global, physical, psychological, environment, and social. Results: The QOL physical domain score was lower for men with KS compar ed 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 pop ulation (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 t o be lower in men with Klinefelter syndrome (KS) compared to the healthy referenc e 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 refe rence 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 comp ared to a healthy European reference population. Especially, the presen ce of discrimination, less social activities, and chronic health problems is associat ed with lower physical, psychological, and social QOL. Further studies are necessary to investigate if a multidisciplinary approach may help to provide adequate counsel ling and psychosocial support to improve QOL

Congenital Hypogonadotropic Hypogonadism Due to GNRH Receptor Mutations in Three Brothers Reveal Sites Affecting Conformation and Coupling

Congenital hypogonadotropic hypogonadism (CHH) is characterized by low gonadotropins and failure to progress normally through puberty. Mutations in the gene encoding the GnRH receptor (GNRHR1) result in CHH when present as compound heterozygous or homozygous inactivating mutations. This study identifies and characterizes the properties of two novel GNRHR1 mutations in a family in which three brothers display normosmic CHH while their sister was unaffected. Molecular analysis in the proband and the affected brothers revealed two novel non-synonymous missense GNRHR1 mutations, present in a compound heterozygous state, whereas their unaffected parents possessed only one inactivating mutation, demonstrating the autosomal recessive transmission in this kindred and excluding X-linked inheritance equivocally suggested by the initial pedigree analysis. The first mutation at c.845 C>G introduces an Arg substitution for the conserved Pro 282 in transmembrane domain (TMD) 6. The Pro282Arg mutant is unable to bind radiolabeled GnRH analogue. As this conserved residue is important in receptor conformation, it is likely that the mutation perturbs the binding pocket and affects trafficking to the cell surface. The second mutation at c.968 A>G introduces a Cys substitution for Tyr 323 in the functionally crucial N/DPxxY motif in TMD 7. The Tyr323Cys mutant has an increased GnRH binding affinity but reduced receptor expression at the plasma membrane and impaired G protein-coupling. Inositol phosphate accumulation assays demonstrated absent and impaired Gαq/11 signal transduction by Pro282Arg and Tyr323Cys mutants, respectively. Pretreatment with the membrane permeant GnRHR antagonist NBI-42902, which rescues cell surface expression of many GNRHR1 mutants, significantly increased the levels of radioligand binding and intracellular signaling of the Tyr323Cys mutant but not Pro282Arg. Immunocytochemistry confirmed that both mutants are present on the cell membrane albeit at low levels. Together these molecular deficiencies of the two novel GNRHR1 mutations lead to the CHH phenotype when present as a compound heterozygote

Autoantibodies against type I IFNs in patients with life-threatening COVID-19

Interindividual clinical variability in the course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is vast. We report that at least 101 of 987 patients with life-threatening coronavirus disease 2019 (COVID-19) pneumonia had neutralizing immunoglobulin G (IgG) autoantibodies (auto-Abs) against interferon-w (IFN-w) (13 patients), against the 13 types of IFN-a (36), or against both (52) at the onset of critical disease; a few also had auto-Abs against the other three type I IFNs. The auto-Abs neutralize the ability of the corresponding type I IFNs to block SARS-CoV-2 infection in vitro. These auto-Abs were not found in 663 individuals with asymptomatic or mild SARS-CoV-2 infection and were present in only 4 of 1227 healthy individuals. Patients with auto-Abs were aged 25 to 87 years and 95 of the 101 were men. A B cell autoimmune phenocopy of inborn errors of type I IFN immunity accounts for life-threatening COVID-19 pneumonia in at least 2.6% of women and 12.5% of men
