- Despite limited and ambiguous empirical data, substance use-related problems have been assumed to be rare among patients with autism spectrum disorders (ASD). Using Swedish population-based registers we identified 26,986 individuals diagnosed with ASD during 1973-2009, and their 96,557 non-ASD relatives. ASD, without diagnosed comorbidity of attention deficit hyperactivity disorder (ADHD) or intellectual disability, was related to a doubled risk of substance use-related problems. The risk of substance use-related problems was the highest among individuals with ASD and ADHD. Further, risks of substance use-related problems were increased among full siblings of ASD probands, half-siblings and parents. We conclude that ASD is a risk factor for substance use-related problems. The elevated risks among relatives of probands with ASD suggest shared familial (genetic and/or shared environmental) liability.

- Objective: To assess the risk of psychiatric disorders and suicide attempts in children with type 1 diabetes and their healthy siblings. Research Design and Methods: We performed a population-based case cohort study of individuals born in Sweden between 1973 and 2009. Children with type 1 diabetes (n=17,122) and their healthy siblings (n=18,847) were identified and followed until their 18th birthday. Their risk of psychiatric disorders was compared with matched controls. Results: The risk of psychiatric morbidity in children with type 1 diabetes compared to the general population was tripled within 6 months after the onset of diabetes (hazard ratio, HR 3.0, 95% confidence interval, CI 2.7-3.4) and doubled within the total observation period (HR 2.1, CI 2.0-2.2). An increased risk was noted in suicide attempts (HR 1.7, CI 1.4-2.0) and in most categories of psychiatric disorders. The risk of psychiatric disorders in probands declined from HR 2.7 (CI 2.2-3.3) for those in the cohort born 1973-1986 to 1.9 (CI 1.8-2.0) in those born 1997-2009. The risk for any psychiatric disorders among siblings of patients with type 1 diabetes was estimated to be HR 1.1 (CI 1.0-1.1) and there was no increased risk in any of the specific category of disorders. Conclusions: Children with type 1 diabetes are at high risk of psychiatric disorders, which seems to be a consequence of the disease rather than due to a common familial etiology. The results support recommendations on comprehensive mental health surveillance in children with type 1 diabetes, especially in recently diagnosed children.

- Response to lithium varies widely between individuals with bipolar disorder (BD). Polygenic risk scores (PRSs) can uncover pharmacogenomics effects and may help predict drug response. Patients (N = 2,510) with BD were assessed for long-term lithium response in the Consortium on Lithium Genetics using the Retrospective Criteria of Long-Term Treatment Response in Research Subjects with Bipolar Disorder score. PRSs for attention-deficit/hyperactivity disorder (ADHD), major depressive disorder (MDD), and schizophrenia (SCZ) were computed using lassosum and in a model including all three PRSs and other covariates, and the PRS of ADHD (β = -0.14; 95% confidence interval [CI]: -0.24 to -0.03; p value = 0.010) and MDD (β = -0.16; 95% CI: -0.27 to -0.04; p value = 0.005) predicted worse quantitative lithium response. A higher SCZ PRS was associated with higher rates of medication nonadherence (OR = 1.61; 95% CI: 1.34-1.93; p value = 2e-7). This study indicates that genetic risk for ADHD and depression may influence lithium treatment response. Interestingly, a higher SCZ PRS was associated with poor adherence, which can negatively impact treatment response. Incorporating genetic risk of ADHD, depression, and SCZ in combination with clinical risk may lead to better clinical care for patients with BD.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- Studies of how gender-diverse individuals experience pregnancy, childbirth, and nursing remain few, mainly focus on the US and contain scarce information about mental health concerns peri-partum. This hinders informed reproductive health decisions and counseling. We used in-depth interviews to examine how gestational gender-diverse individuals in Sweden experience the process of planning and undergoing pregnancy, delivery, and nursing. In total, 12 participants, identifying on the masculine side of the gender spectrum or as non-binary, who had attended Swedish antenatal care and delivered a live birth, were included in the study. Data were analyzed using qualitative thematic content analysis. The analysis resulted in one overarching theme: sustaining gender congruence during pregnancy and three main categories: (1) considering pregnancy; (2) undergoing pregnancy and childbirth; and (3) postnatal reflections. The association between childbearing and being regarded as female permeated narratives. Participants renegotiated the feminine connotations of pregnancy, accessed gender-affirming treatment, and concealed their pregnancy to safeguard their gender congruence. Mis-gendering and breast enlargement triggered gender dysphoria. Social judgment, loneliness, information shortages, hormonal influence and cessation of testosterone increased gender dysphoria and strained their mental health. Depression exacerbated gender dysphoria and made it harder to claim one's gender identity. Dissociation was used to handle a feminized body, vaginal delivery, and nursing. Pregnancy was easier to envision and handle after masculinizing gender-affirming treatments. The results deepen the understanding of gender dysphoria and may be used to inform reproductive counseling and healthcare development. Research outcomes on mental health concerns provide a basis for further research.

- Background: A sterilization requirement to change legal gender was removed from Swedish law in 2013, facilitating pregnancy in trans masculine individuals. The limited number of studies investigating pregnancy and childbirth among trans masculine individuals indicate increased gender dysphoria and negative experiences of pre- and post-natal healthcare, highlighting a need to improve care. Research focusing on Europe or contexts where sterilization to change legal gender was previously required by national law remains minimal.Aims: This study aimed to investigate how trans masculine individuals experience healthcare encounters in connection with pregnancy, delivery and nursing, in a setting where mandatory sterilization to change legal gender was recently removed.Methods: In-depth face-to-face interviews were conducted with 12 trans masculine individuals who attended Swedish prenatal care and delivered a child after the law on legal gender recognition was amended. Thematic content analysis was used.Results: Providers in gender clinics, antenatal care and delivery were perceived to regard a masculine gender identity and pregnancy as incompatible. The main categories encompassed expectations and experiences of pregnancy related care and participant responses to it. Participants took charge of their care to ensure that their needs were fulfilled. The quality of care was inconsistent.Discussion: A lack of knowledge, narrow gender norms and the legacy of the former legal sterility requirement limited access to diagnostic evaluation of gender dysphoria, information on reproduction and gender-affirming treatment. Medical safety during pregnancy, childbirth and nursing was impeded, gender dysphoria increased, and participants experienced minority stress. Attempts to avoid microaggressions guided healthcare encounters and birth wishes. Navigating healthcare required considerable attention, personal resources and energy, leaving particularly vulnerable individuals at risk of a lower quality of care. The paper concludes with clinical recommendations.

- 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.
