- BACKGROUND: Hypospadias (aberrant opening of the urethra on the underside of the penis) occurs in 1 per 300 newborn boys. It has been previously unknown whether this common malformation is associated with increased psychiatric morbidity later in life. Studies of individuals with hypospadias also provide an opportunity to examine whether difference in androgen signaling is related to neurodevelopmental disorders. To elucidate the mechanisms behind a possible association, we also studied psychiatric outcomes among brothers of the hypospadias patients. METHODS: Registry study within a national cohort of all 9,262 males with hypospadias and their 4,936 healthy brothers born in Sweden between 1973 and 2009. Patients with hypospadias and their brothers were matched with controls by year of birth and county. The following outcomes were evaluated (1) any psychiatric (2) psychotic, (3) mood, (4) anxiety, (5) eating, and (6) personality disorders, (7) substance misuse, (8) attention-deficit hyperactivity disorder (ADHD), (9) autism spectrum disorders (ASD), (10) intellectual disability, and (11) other behavioral/emotional disorders with onset in childhood. RESULTS: Patients with hypospadias were more likely to be diagnosed with intellectual disability (OR 3.2; 95% CI 2.8-3.8), ASD (1.4; 1.2-1.7), ADHD (1.5; 1.3-1.9), and behavioral/emotional disorders (1.4; 1.2-1.6) compared with the controls. Brothers of patients with hypospadias had an increased risk of ASD (1.6; 1.3-2.1) and other behavioral/emotional disorders with onset in childhood (1.2; 0.9-1.5) in comparison to siblings of healthy individuals. A slightly higher, although not statistically significant, risk was found for intellectual disability (1.3; 1.0-1.9). No relation between other psychiatric diagnosis and hypospadias was found. CONCLUSIONS: This is the first study to identify an increased risk for neurodevelopmental disorders in patients with hypospadias, as well as an increased risk for ASD in their brothers, suggesting a common familial (genetic and/or environmental) liability.

- Congenital adrenal hyperplasia (CAH) is a chronic condition and individuals are exposed to elevated androgen levels in utero as a result of the endogenous cortisol deficiency. Prenatal androgen exposure has been suggested to influence mental health, but population based studies on psychiatric morbidity among girls and women with CAH are lacking. Therefore, we performed a cohort study based on Swedish nationwide registers linked with the national CAH register. Girls and women with CAH due to 21-hydroxylase deficiency (n=335) born between January 1915 and January 2010 were compared with aged-matched female (n=33500) and male controls (n=33500). Analyses were stratified by phenotype [salt wasting (SW), simple virilizing (SV), and non-classical type (NC)] and by CYP21A2 genotype subgroups (null, I2splice, I172N, and P30L). Results are presented as estimated risks (OR, 95%CI) of psychiatric disorders among girls and women with CAH compared with age-matched controls. Any psychiatric diagnoses were more common in CAH females compared with female and male population controls [1.9 (1.4-2.5), and 2.2 (1.7-2.9)]. In particular, the risk of alcohol misuse was increased compared with female and male population controls [2.8 (1.7-4.7) and 2.1 (1.2-3.5)], and appeared most common among the girls and women with the most severe null genotype [6.7 (2.6-17.8)]. The risk of stress and adjustment disorders was doubled compared with female population controls [2.1 (1.3-3.6)]. Girls and women with CAH have an increased risk of psychiatric disorders in general and substance use disorders in particular compared with unexposed females, with the highest risk among those with the most severe genotype. Prenatal androgen exposure and deficient endogenous cortisol and/or adrenaline production may provide explanations for these findings, but other factors related to CAH cannot be excluded.

- CONTEXT: Congenital adrenal hyperplasia (CAH) is lethal in its most severe forms if not treated with glucocorticoids. However, glucocorticoids may increase the risk of cardiovascular and metabolic morbidity. OBJECTIVE: This study aimed to study cardiovascular and metabolic morbidity in CAH. DESIGN, SETTING, AND PARTICIPANTS: Patients with CAH due to 21-hydroxylase deficiency (n = 588; >80% with known CYP21A2 mutations) were compared with controls matched for sex, year, and place of birth (n = 58 800). Data were obtained by linking national population-based registers. Subgroup analyses were performed regarding sex, clinical severity (salt wasting, simple virilizing, nonclassic), CYP21A2 genotype (null, I2 splice, I172N, P30L), and stratified by the introduction of neonatal screening, age groups, and nonobesity. MAIN OUTCOME MEASURES: To study cardiovascular and metabolic morbidity in CAH. RESULTS: In CAH, both any cardiovascular and metabolic disorders (OR [odds ratio], 3.9; 95% CI [confidence interval], 3.1-5.0), and cardiovascular disease (OR, 2.7; 95% CI, 1.9-3.9) were increased. Separate analyses of the individual diseases showed higher frequencies in CAH of hypertension, hyperlipidemia, atrial fibrillation, venous thromboembolism, obesity, diabetes (mainly type 2), obstructive sleep disorder, thyrotoxicosis, and hypothyroidism. Similar results were seen in the stratified groups. On the subgroup level, females were generally more affected (especially I172N and the nonclassic group), as were males with the null genotype. CONCLUSIONS: CAH was associated with excess cardiovascular and metabolic morbidity but the mechanism is not certain as the glucocorticoids were not assessed. Hypothyroidism and obesity may be an effect of close observation. However, more severe conditions were presumably detected equally in patients and controls. Screening for diabetes and other metabolic disorders that increase cardiovascular risk is important.

- Context: Reports on mortality in patients with congenital adrenal hyperplasia (CAH) are lacking. Objective: To study mortality and causes of death in CAH. Design, Setting and Participants: We studied patients with CAH (21-hydroxylase deficiency, n=588; CYP21A2 mutations known, >80%), and compared them with controls (n=58800). Data were derived through linkage of national population-based registers. Main Outcome Measures: Mortality and causes of death. Results: The mean age of death was 41.2±26.9 years in CAH patients and 47.7±27.7 years in controls (P<0.001). Among CAH patients 23 (3.9%) had deceased compared to 942 (1.6%) of controls. The hazard ratio (and 95% confidence interval) of death was 2.3(1.2-4.3) in CAH males and 3.5(2.0-6.0) in CAH females. Including only patients born 1952-2009, gave similar total results but only patients with salt-wasting or with unclear phenotype had an increased mortality. The causes of death in CAH patients were adrenal crisis (42%), cardiovascular (32%), cancer (16%), and suicide (10%). There were seven additional deaths in CAH individuals with incomplete or reused personal identification number that could not be analyzed using linkage of registers. Of the latter all except one were deceased before the introduction of neonatal screening in 1986 and most of them in the first weeks of life, probably in an adrenal crisis. Conclusions: CAH is a potentially lethal condition and was associated with excess mortality due to adrenal crisis. The salt-wasting phenotype seemed to have worse outcome also in children and adults due to adrenal crisis and not only before the introduction of neonatal screening.

- Context:Reports on psychiatric morbidity in males with congenital adrenal hyperplasia (CAH) are lacking.Objective:To study psychiatric disorders in CAH males.Design, Setting and Participants:We studied males with CAH (21-hydroxylase deficiency, n=253; CYP21A2 mutations known, n=185), and compared them with controls (n=25300). Data were derived through linkage of national population-based registers. We assessed the subgroups of CYP21A2 genotype separately (null, I2splice, I172N, P30L and NC), as well as outcomes before and after the introduction of national neonatal screening in 1986.Main Outcome Measures:Psychiatric disorders including attempted and completed suicide (suicidality).Results:Psychiatric disorders (suicidality not included), suicidality and alcohol misuse were increased in CAH males compared with controls (OR 1.5, 2.3, and 1.9; 95%CI 1.1-2.2, 1.1-5.0, and 1.0-3.5). In the null genotype group, no increased rates were seen; in the I2splice group, psychiatric disorders, personality disorders and alcohol misuse were increased; in the I172N group suicide attempt and drug misuse were increased; and in the P30L and NC group psychotic disorders were increased. In CAH males born before the neonatal screening, the rate of psychiatric disorders and suicidality were increased, but only psychotic disorders in those born after. There was no increased risk for any neurodevelopmental disorder.Conclusions:CAH males have an increased psychiatric morbidity. Psychiatric morbidity was not raised in the most severe genotype group. Late diagnosis of CAH may explain some of the findings. Those born before the introduction of neonatal screening were more affected, which may be explained by the higher age.

- Both prenatal and circulating testosterone and other androgens have been suggested to influence the individual's propensity to commit crime, but empirical evidence is limited and inconsistent. Congenital Adrenal Hyperplasia (CAH) and Polycystic Ovary Syndrome (PCOS) are both hyperandrogenic conditions but with an important difference; whereas subjects with CAH are exposed to high concentrations of androgens in utero, women with PCOS are subjected to high androgens in adulthood. Comparing these groups can therefore yield important insights of androgenic effects on behavior. In the current study, information on medical diagnoses and convicted crimes were gathered from Swedish population-based registers. The associations between diagnoses of CAH or PCOS and any crime, violent crime or sex crime were estimated with conditional logistic regression. Results showed that CAH in women and men did not predict criminality, whereas an increased risk for any crime and violent crime was found in PCOS women. Our findings indicate that female hyperandrogenism in adulthood, but not prenatal hyperandrogenism, is associated with risk for criminal behavior. Further research into hyperandrogenic conditions holds opportunities to deepen our understanding of the etiology of crime and psychopathology. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

- Background: Congenital adrenal hyperplasia (CAH) is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000. About one in 70 individuals in the general population are carriers of a severe CYP21A2 mutation. It has been suggested that this confers a survival advantage, perhaps as a result of increased activity in the hypothalamic–pituitary–adrenal axis. We investigated vulnerability to psychological stress in obligate carriers. Method: The Swedish CAH Registry encompasses more than 600 patients. Parents, that is obligate carriers of the CYP21A2 mutation, were identified through the Multigeneration Register. The diagnosis of the child was used as the psychological stressor. Psychiatric diagnoses before and after the birth of a child with CAH were compared to those of controls derived from (i) the general population, (ii) parents of children with hypospadias and (iii) parents of children with diabetes mellitus type 1 (T1DM). Results: Parents of children with CAH had less risk of being diagnosed with any psychiatric disorder (OR, 0 6), an affective disorder (OR, 0 5) or substance misuse (OR, 0 5) after the diagnosis of the child, compared to the general population. Their risk was also decreased compared to parents of a child with hypospadias (OR, 0 6, 0 4 and 0 2, respectively) and parents of a child with T1DM (OR 0 7, 0 6 and 0 2, respectively). The CYP21A2 carriers had a lower risk of developing mood and stress-related disorders after the diagnosis of the child. Conclusion: Obligate CYP21A2 carriers had a reduced risk of a psychiatric diagnosis and were less vulnerable to a psychologically stressful situation, at least with respect to receiving a psychiatric diagnosis. This indicates a better ability to cope with psychological stress among heterozygous carriers of severe CYP21A2 mutations, which may contribute to the apparent survival advantage

- CONTEXT: Females with congenital adrenal hyperplasia (CAH) due to a CYP21A2 deficiency are exposed to androgens during fetal development, resulting in virilization of the external genitalia. Little is known about how these women feel that the disease has affected their lives regarding surgery and psychosexual adaptation. OBJECTIVE: Our objective was to investigate the correlation between the surgical results, the self-perceived severity of the disease, and satisfaction with sexual life and relate the results to the CYP21A2 genotype. DESIGN AND PARTICIPANTS: Sixty-two Swedish women with CAH and age-matched controls completed a 120-item questionnaire, and a composite score for sexual function was constructed. The surgical outcome, including genital appearance and clitoral sensitivity, was evaluated by clinical examination. The patients were divided into four CYP21A2 genotype groups. RESULTS: The sexual function score, but not for genital appearance, was higher in the patients satisfied with their sexual life. This was also true of the patients who were satisfied with the surgical result. There were discrepancies between the patients' perception of the impact of the condition on their sexual life and what health professionals would assume from clinical examination. The patients in the null genotype group scored lower on sexual function and satisfaction with their sexual life and had more surgical complications, also compared with the slightly less severe I2-splice genotype group. CONCLUSION: Our data show that the null genotype group was considerably more affected by the condition than the other groups and should be regarded as a subgroup, both psychologically and from a surgical perspective. Genotyping adds clinically valuable information.

Hypospadias as a novel feature in spinal bulbar muscle atrophy

Tidskriftsartikel (refereegranskat)abstract
- Spinal and bulbar muscle atrophy (SBMA) is an X-linked neuromuscular disorder caused by CAG repeat expansions in the androgen receptor (AR) gene. The SBMA phenotype consists of slowly progressive neuromuscular symptoms and undermasculinization features as the result of malfunction of the AR. The latter mainly includes gynecomastia and infertility. Hypospadias is also a feature of undermasculinization with an underdeveloped urethra and penis; it has not been described as part of the SBMA phenotype but has been suggested to be associated with a prolonged CAG repeat in the AR gene. This study includes the first epidemiologic description of the co-occurrence of hypospadias and SBMA in subjects and their male relatives in Swedish population-based health registers, as well as an additional clinical case. One boy with severe hypospadias was screened for mutations in the AR gene and was found to have 42 CAG repeats in it, which is in the full range of mutations causing SBMA later in life. We also detected a maximum of four cases displaying the combination of SBMA and hypospadias in our national register databases. This is the third case report with hypospadias in association with CAG repeat expansions in the AR gene in the full range known to cause SBMA later in life. Our findings suggest that hypospadias may be an under diagnosed feature of the SBMA phenotype and we propose that neurologists working with SBMA further investigate and report the true prevalence of hypospadias among patients with SBMA.

- PURPOSE: We present data on long-term functional and cosmetic results after hypospadias surgery. MATERIALS AND METHODS: Males older than 18 years with hypospadias treated in Sweden were asked to participate in the study, as well as age matched controls and circumcised men. All participants answered questionnaires, and a subgroup was examined during an outpatient visit. Relationships with outcome were analyzed using analysis of variance and regression analysis. RESULTS: A total of 167 patients with a mean age of 34 years and 169 controls with a mean age of 33 years answered the questionnaire. Of the patients 63% had distal, 24% mid and 13% proximal hypospadias. A total of 46 patients and 49 controls presented for physical examination. Patients were significantly less satisfied with the penile cosmetic outcome regarding all parameters of the Penile Perception Score. There was a difference in penile length between patients and controls (mean 9.7 vs 11.6 cm, p <0.001). More patients than controls reported voiding dysfunction symptoms (p = 0.003). Patients had a lower maximum urinary flow rate than controls (p = 0.001). These differences were most prominent between patients with proximal hypospadias and controls. CONCLUSIONS: Men operated on for hypospadias were less satisfied with the cosmetic result than controls, and had a shorter penile length. Patients presented with more symptoms of voiding dysfunction and displayed a lower maximum urinary flow rate. Patients with proximal hypospadias were more affected than those with milder hypospadias. Our results indicate that patients with hypospadias can be subgrouped and that those with severe phenotypes should be followed more closely during childhood as well as later in adulthood.
