RESUMO
Purpose: Transgender and gender diverse (TGD) youth in North American clinical reports are predominantly White with relatively high socioeconomic status suggesting that access to gender-affirming care is inequitable. This study examined whether socioeconomic and social determinant of health discrepancies exist between a clinical population of TGD youth and surrounding communities. Methods: Patient postal codes were used to link the Ontario Marginalization Index (ON-MARG) to a clinic-based TGD youth cohort (n = 298). Using ON-MARG, each patient was assigned a quintile score from 1 (least marginalized) to 5 (most marginalized) on four marginalization measures. Mean quintile scores were compared to background populations. Census-based Toronto neighborhood-level data on ethnic diversity and educational status were also examined. Neighborhoods were categorized as highly represented, less represented, or unrepresented based on representation in the clinic cohort. One-way analysis of covariance was used to determine associations between neighborhood-level variables and the degree of neighborhood representation. Results: ON-MARG data demonstrated that clinic patients hailed from areas with more individuals having paid employment. Patients from Toronto and surrounding areas came, in general, from communities with fewer recent immigrants and visible minorities. Highly represented Toronto neighborhoods had smaller proportions of visible minorities and immigrants compared with less and unrepresented neighborhoods. Educational status, represented by adults with bachelor's degrees, was lower among unrepresented neighborhoods. Conclusion: TGD youth seen in clinic, particularly those from Toronto, are disproportionally White and socioeconomically advantaged. Further research is needed to better understand the underrepresentation of racialized and low-socioeconomic status youth and to inform strategies to improve access to care.
RESUMO
Gender dysphoria (GD) and obesity share commonalities, including associations with mental health comorbidities, disordered eating, body dissatisfaction and may intensify with physical and developmental changes during adolescence. While associations of obesity and gender diversity have been identified, rates of gender diversity among adolescents with obesity remain unclear. The aim was to examine gender diversity among adolescents with obesity in a weight management programme. A single-centre cross-sectional questionnaire study was conducted. Eligible adolescents received the Gender Identity/GD Questionnaire for Adolescents and Adults (GIDYQ-AA), a validated instrument measuring gender diversity and GD. Gender identities, sexual orientations, questionnaire scores, and frequency of GD (GIDYQ-AA score <3) were determined. The relationship of GIDYQ-AA scores and BMI Z-score (BMIz) was assessed. Of 72 consenting youth, 29 assigned females (AF) and 17 assigned males (AM) completed GIDYQ-AA and demographic questions. Seventeen (59%) AF reported non-heterosexual orientations, and 6 (21%) reported non-cisgender identities. One (6%) AM reported non-cisgender identity. Two (4%) AF individuals had GD based on GIDYQ-AA scores. GIDYQ-AA scores did not correlate with BMIz. In conclusion, adolescents with obesity, particularly AF with non-heterosexual orientation, reported high rates of non-cisgender identity and GD. Routine screening for gender-related concerns in weight management settings may be warranted.

CONTEXT: Constitutional delay of puberty (CDP) is highly heritable, but the genetic basis for CDP is largely unknown. Idiopathic hypogonadotropic hypogonadism (IHH) can be caused by rare genetic variants, but in about half of cases, no rare-variant cause is found. OBJECTIVE: To determine whether common genetic variants that influence pubertal timing contribute to CDP and IHH. DESIGN: Case-control study. PARTICIPANTS: 80 individuals with CDP; 301 with normosmic IHH, and 348 with Kallmann syndrome; control genotyping data from unrelated studies. MAIN OUTCOME MEASURES: Polygenic scores (PGS) based on genome-wide association studies for timing of male pubertal hallmarks and age at menarche (AAM). RESULTS: The CDP cohort had higher PGS for male pubertal hallmarks and for AAM compared to controls (for male hallmarks, Cohen's d = 0.85, p = 1 × 10-16; for AAM, d = 0.67, p = 1 × 10-10). The normosmic IHH cohort also had higher PGS for male hallmarks compared to controls, but the difference was smaller (male hallmarks d = 0.20, p = 0.003; AAM d = 0.10, p = 0.055). No differences were seen for the KS cohort compared to controls (male hallmarks d = 0.04, p = 0.45; AAM d = -0.03, p = 0.86). CONCLUSIONS: Common genetic variants that influence pubertal timing in the general population contribute strongly to the genetics of CDP, weakly to normosmic IHH, and potentially not at all to KS. These findings demonstrate that the common-variant genetics of CDP and normosmic IHH are largely but not entirely distinct.
RESUMO
BACKGROUND: Gender clinic and single-item questionnaire-based data report increased co-occurrence of gender diversity and neurodevelopmental conditions. The nuances of these associations are under-studied. We used a transdiagnostic approach, combining categorical and dimensional characterization of neurodiversity, to further the understanding of its associations with gender diversity in identity and expression in children. METHODS: Data from 291 children (Autism N = 104, ADHD N = 104, Autism + ADHD N = 17, neurotypical N = 66) aged 4-12 years enrolled in the Province of Ontario Neurodevelopmental Network were analyzed. Gender diversity was measured multi-dimensionally using a well-validated parent-report instrument, the Gender Identity Questionnaire for Children (GIQC). We used gamma regression models to determine the significant correlates of gender diversity among age, puberty, sex-assigned-at-birth, categorical neurodevelopmental diagnoses, and dimensional neurodivergent traits (using the Social Communication Questionnaire and the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Rating Scales). Internalizing and externalizing problems were included as covariates. RESULTS: Neither a categorical diagnosis of autism nor ADHD significantly correlated with current GIQC-derived scores. Instead, higher early-childhood dimensional autistic social-communication traits correlated with higher current overall gender incongruence (as defined by GIQC-14 score). This correlation was potentially moderated by sex-assigned-at-birth: greater early-childhood autistic social-communication traits were associated with higher current overall gender incongruence in assigned-males-at-birth, but not assigned-females-at-birth. For fine-grained gender diversity domains, greater autistic restricted-repetitive behavior traits were associated with greater diversity in gender identity across sexes-assigned-at-birth; greater autistic social-communication traits were associated with lower stereotypical male expression across sexes-assigned-at-birth. CONCLUSIONS: Dimensional autistic traits, rather than ADHD traits or categorical neurodevelopmental diagnoses, were associated with gender diversity domains across neurodivergent and neurotypical children. The association between early-childhood autistic social-communication traits and overall current gender diversity was most evident in assigned-males-at-birth. Nuanced interrelationships between neurodivergence and gender diversity should be better understood to clarify developmental links and to offer tailored support for neurodivergent and gender-diverse populations.
RESUMO
BACKGROUND: The pan-Canadian Maternal-Infant Research on Environmental Chemicals (MIREC) study was established to determine whether maternal environmental chemical exposures were associated with adverse pregnancy outcomes in 2001 pregnant women. OBJECTIVES: The MIREC-Child Development (CD PLUS) study followed this cohort with the goal of assessing the potential effects of prenatal exposures on anthropometry and neurodevelopment in early childhood. POPULATION: MIREC families with children between the ages of 15 months and 5 years who had agreed to be contacted for future research (n = 1459) were invited to participate in MIREC-CD PLUS which combines data collected from an online Maternal Self-Administered Questionnaire with biomonitoring and neurodevelopment data collected from two in-person visits. PRELIMINARY RESULTS: Between April 2013 and March 2015, 803 children participated in the Biomonitoring visit where we collected anthropometric measures, blood, and urine from the children. The Behavioural Assessment System for Children-2, Behaviour Rating Inventory of Executive Function, MacArthur-Bates Communicative Development Inventories and the Communication subscale of the Adaptive Behaviour Scale from the Bayley Scales of Infant and Toddler Development-III are available on close to 900 children. There were 610 singleton children who completed in-person visits for neurodevelopment assessments including the Social Responsiveness Scale, Wechsler Preschool Primary Scale of Intelligence-III and NEuroPSYchological assessments (NEPSY). Currently, we are following the cohort into early adolescence to measure the impact of early life exposures on endocrine and metabolic function (MIREC-ENDO). CONCLUSIONS: Data collection for the MIREC-CD PLUS study is complete and analysis of the data continues. We are now extending the follow-up of the cohort into adolescence to measure the impact of early life exposures on endocrine and metabolic function (MIREC-ENDO). MIREC-CD PLUS is limited by loss to follow-up and the fact that mothers are predominately of higher socioeconomic status and 'White' ethnicity, which limits our generalizability. However, the depth of biomonitoring and clinical measures in MIREC provides a platform to examine associations of prenatal, infancy and childhood exposures with child growth and development.

CONTEXT: The melanocortin 3 receptor (MC3R) has recently emerged as a critical regulator of pubertal timing, linear growth, and the acquisition of lean mass in humans and mice. In population-based studies, heterozygous carriers of deleterious variants in MC3R report a later onset of puberty than noncarriers. However, the frequency of such variants in patients who present with clinical disorders of pubertal development is currently unknown. OBJECTIVE: This work aimed to determine whether deleterious MC3R variants are more frequently found in patients clinically presenting with constitutional delay of growth and puberty (CDGP) or normosmic idiopathic hypogonadotropic hypogonadism (nIHH). METHODS: We examined the sequence of MC3R in 362 adolescents with a clinical diagnosis of CDGP and 657 patients with nIHH, experimentally characterized the signaling properties of all nonsynonymous variants found and compared their frequency to that in 5774 controls from a population-based cohort. Additionally, we established the relative frequency of predicted deleterious variants in individuals with self-reported delayed vs normally timed menarche/voice-breaking in the UK Biobank cohort. RESULTS: MC3R loss-of-function variants were infrequent but overrepresented in patients with CDGP (8/362 [2.2%]; OR = 4.17; P = .001). There was no strong evidence of overrepresentation in patients with nIHH (4/657 [0.6%]; OR = 1.15; P = .779). In 246 328 women from the UK Biobank, predicted deleterious variants were more frequently found in those self-reporting delayed (aged ≥16 years) vs normal age at menarche (OR = 1.66; P = 3.90E-07). CONCLUSION: We have found evidence that functionally damaging variants in MC3R are overrepresented in individuals with CDGP but are not a common cause of this phenotype.

BACKGROUND: The pituitary gland regulates essential physiological processes such as growth, pubertal onset, stress response, metabolism, reproduction, and lactation. While sex biases in these functions and hormone production have been described, the underlying identity, temporal deployment, and cell-type specificity of sex-biased pituitary gene regulatory networks are not fully understood. METHODS: To capture sex differences in pituitary gene regulation dynamics during postnatal development, we performed 3' untranslated region sequencing and small RNA sequencing to ascertain gene and microRNA expression, respectively, across five postnatal ages (postnatal days 12, 22, 27, 32, 37) that span the pubertal transition in female and male C57BL/6J mouse pituitaries (n = 5-6 biological replicates for each sex at each age). RESULTS: We observed over 900 instances of sex-biased gene expression and 17 sex-biased microRNAs, with the majority of sex differences occurring with puberty. Using miRNA-gene target interaction databases, we identified 18 sex-biased genes that were putative targets of 5 sex-biased microRNAs. In addition, by combining our bulk RNA-seq with publicly available male and female mouse pituitary single-nuclei RNA-seq data, we obtained evidence that cell-type proportion sex differences exist prior to puberty and persist post-puberty for three major hormone-producing cell types: somatotropes, lactotropes, and gonadotropes. Finally, we identified sex-biased genes in these three pituitary cell types after accounting for cell-type proportion differences between sexes. CONCLUSION: Our study reveals the identity and postnatal developmental trajectory of sex-biased gene expression in the mouse pituitary. This work also highlights the importance of considering sex biases in cell-type composition when understanding sex differences in the processes regulated by the pituitary gland.

Extensive evidence supports the role of the immune system in modulating brain function and behaviour. However, past studies have revealed striking heterogeneity in behavioural phenotypes produced from immune system dysfunction. Using magnetic resonance imaging, we studied the neuroanatomical differences among 11 distinct genetically modified mouse lines (n = 371), each deficient in a different element of the immune system. We found a significant and heterogeneous effect of immune dysfunction on the brains of both male and female mice. However, by imaging the whole brain and using Bayesian hierarchical modelling, we were able to identify patterns within the heterogeneous phenotype. Certain structures-such as the corpus callosum, midbrain, and thalamus-were more likely to be affected by immune dysfunction. A notable brain-behaviour relationship was identified with neuroanatomy endophenotypes across mouse models clustering according to anxiety-like behaviour phenotypes reported in literature, such as altered volume in brains regions associated with promoting fear response (e.g., the lateral septum and cerebellum). Interestingly, genes with preferential spatial expression in the most commonly affected regions are also associated with multiple sclerosis and other immune-mediated diseases. In total, our data suggest that the immune system modulates anxiety behaviour through well-established brain networks.

Pediatric endocrinologists often evaluate and treat youth with delayed puberty. Stereotypically, these patients are 14-year-old young men who present due to lack of pubertal development. Concerns about stature are often present, arising from gradual shifts to lower height percentiles on the population-based, cross-sectional curves. Fathers and/or mothers may have also experienced later than average pubertal onset. In this review, we will discuss a practical clinical approach to the evaluation and management of youth with delayed puberty, including the differential diagnosis and key aspects of evaluation and management informed by recent review of the existing literature. We will also discuss scenarios that pose additional clinical challenges, including: (1) the young woman whose case poses questions regarding how presentation and approach differs for females vs males; (2) the 14-year-old female or 16-year-old young man who highlight the need to reconsider the most likely diagnoses, including whether idiopathic delayed puberty can still be considered constitutional delay of growth and puberty at such late ages; and finally (3) the 12- to 13-year-old whose presentation raises questions about whether age cutoffs for the diagnosis and treatment of delayed puberty should be adjusted downward to coincide with the earlier onset of puberty in the general population.

With the declining age at onset of puberty and increasing prevalence of childhood obesity, early breast development in young obese girls has become a more frequent occurrence. Here, we examine available literature to answer a series of questions regarding how obesity impacts the evaluation and management of precocious puberty. We focus on girls as the literature is more robust, but include boys where literature permits. Suggestions include: (1) Age cutoffs for evaluation of precocious puberty should not differ substantially from those used for nonobese children. Obese girls with confirmed thelarche should be evaluated for gonadotropin-dependent, central precocious puberty (CPP) to determine if further investigation or treatment is warranted. (2) Basal luteinizing hormone (LH) levels remain a recommended first-line test. However, if stimulation testing is utilized, there is a theoretical possibility that the lower peak LH responses seen in obesity could lead to a false negative result. (3) Advanced bone age (BA) is common among obese girls even without early puberty; hence its diagnostic utility is limited. (4) Obesity does not eliminate the need for magnetic resonance imaging in girls with true CPP. Age and clinical features should determine who warrants neuroimaging. (5) BA can be used to predict adult height in obese girls with CPP to inform counseling around treatment. (6) Use of gonadotropin-releasing hormone analogues (GnRHa) leads to increased adult height in obese girls. (7) Obesity should not limit GnRHa use as these agents do not worsen weight status in obese girls with CPP.
RESUMO
OBJECTIVES: To promote resource stewardship in thyroid hormone testing at a pediatric tertiary care hospital. STUDY DESIGN: Quality improvement approaches generated 3 change ideas that were implemented simultaneously in the hospital electronic medical record: (1) a reflex free thyroxine (fT4), whereby fT4 is automatically reported if the thyroid-stimulating hormone is outside the normal range; (2) a forced-function for thyroid hormone ordering, whereby a provider must select an appropriate indication for ordering fT4 or triiodothyronine (T3); and (3) a clinical decision support message displayed at the time of ordering thyroid function tests. Laboratory data were audited to determine the mean number of fT4 and T3 tests performed per week as well as indications for testing. RESULTS: The mean number of fT4 and T3 tests processed per week decreased from 154 ± 21 and 11 ± 7, respectively, in the preintervention period, to 107 ± 12 (30% reduction) and 4 ± 3 (66% reduction) postintervention. These reductions were sustained for the full 20-week assessment period. Process and balancing measures revealed no unintended adverse consequences. Approximate cost savings were $43 000 per year. CONCLUSIONS: We describe the successful implementation of electronic medical record-based interventions (reflex fT4, forced-function selection of indication, decision support text) leading to sustained improvements in healthcare use, with significant associated cost-savings.

BACKGROUND: Gender-incongruent youth may present to gender-affirming medical care (GAMC) later in adolescence and puberty when hormone blockers provide less benefit. Factors influencing age of presentation to GAMC have not been described. METHODS: A sequential mixed methods study. Participants were categorized on the basis of age at presentation to GAMC. Youth presenting at ≥15 years comprised the older-presenting youth, whereas those presenting at <15 years comprised the younger-presenting youth. Caregivers were categorized on the basis of the youth's age of presentation. Twenty-four individuals were interviewed, 6 youth and 6 caregivers from each age category. Thematic analysis identified themes related to timing of presentation to GAMC. Themes differentially endorsed between older and younger youth or between caregivers of older and younger youth were used to design a questionnaire distributed to 193 youths and 187 caregivers. Responses were compared between age groups for youths and caregivers. RESULTS: Five themes differed between age groups: validity of gender identity, gender journey barriers, influential networks, perceptions of medical therapy, and health care system interactions. Questionnaires were completed by 121 youths and 121 caregivers. Compared with younger-presenting youth, older-presenting youth recognized gender incongruence at older ages, were less likely to have caregivers who helped them access care or LGBTQ+ (lesbian, gay, bisexual, transgender, queer) family members, more often endorsed familial religious affiliations, and experienced greater youth-caregiver disagreement around importance of GAMC. CONCLUSIONS: Family environment appears to be a key determinant of when youth present to GAMC. Whether this association occurs through affecting transgender identity formation and recognition requires further study.

Maternal environmental exposures, such as high-fat diets, diabetes and obesity, can induce long-term effects in offspring. These effects include increased risk of neurodevelopmental disorders (NDDs) including autism spectrum disorder (ASD), depression and anxiety. The mechanisms underlying these late-life neurologic effects are unknown. In this article, we measured changes in the offspring brain and determined which brain regions are sensitive to maternal metabolic milieu and therefore may mediate NDD risk. We showed that mice exposed to a maternal high-fat diet display extensive brain changes in adulthood despite being switched to a low-fat diet at weaning. Brain regions impacted by early-life diet include the extended amygdalar system, which plays an important role in reward-seeking behaviour. Genes preferentially expressed in these regions have functions related to feeding behaviour, while also being implicated in human NDDs, such as autism. Our data demonstrated that exposure to maternal high-fat diet in early-life leads to brain alterations that persist into adulthood, even after dietary modifications.

OBJECTIVES: Hypoglycemia is the most common acute complication of type 1 diabetes (T1D), and the potential short- and long-term sequelae can cause children and parents to develop significant fear of hypoglycemia (FOH). FOH and associated anxiety can be disruptive to activities of daily living and lead to reduced quality of life. We sought to determine the extent of FOH among parents of children with T1D within our clinic and to identify factors associated with greater FOH. METHODS: Two hundred sixty-four parents of youth (2 to 18 years of age; mean ± standard deviation, 12.4±3.5 years) with T1D completed a survey that included demographic and disease-specific questions, the Spielberger State-Trait Anxiety Inventory and the Hypoglycemia Fear Survey---Parent version (HFS-P). RESULTS: Of the 264 participants, 207 completed the full HFS-P, with a mean score of 67±19 (range, 31 to 119). The most frequent worries related to the child being hypoglycemic while alone or asleep. Higher HFS-P scores were also associated with more frequent and severe hypoglycemic episodes, higher state-trait anxiety scores, use of a continuous glucose monitor and more frequent blood glucose checks. Higher HFS-P scores were also associated with worse parental sleep quality and less parental engagement with treatment plans. CONCLUSIONS: Parents of children with T1D experience FOH, especially during times of high vulnerability. Moreover, FOH could potentially impact clinical care (with parents being reluctant to administer suggested insulin doses) and quality of life (due to parental/child sleep disruption). Further studies are needed to develop and evaluate interventions aimed at reducing FOH in parents of youth with T1D.

BACKGROUND: Carbohydrate counting is an important component of diabetes management, but it is challenging, often performed inaccurately, and can be a barrier to optimal diabetes management. iSpy is a novel mobile app that leverages machine learning to allow food identification through images and that was designed to assist youth with type 1 diabetes in counting carbohydrates. OBJECTIVE: Our objective was to test the app's usability and potential impact on carbohydrate counting accuracy. METHODS: Iterative usability testing (3 cycles) was conducted involving a total of 16 individuals aged 8.5-17.0 years with type 1 diabetes. Participants were provided a mobile device and asked to complete tasks using iSpy app features while thinking aloud. Errors were noted, acceptability was assessed, and refinement and retesting were performed across cycles. Subsequently, iSpy was evaluated in a pilot randomized controlled trial with 22 iSpy users and 22 usual care controls aged 10-17 years. Primary outcome was change in carbohydrate counting ability over 3 months. Secondary outcomes included levels of engagement and acceptability. Change in HbA1c level was also assessed. RESULTS: Use of iSpy was associated with improved carbohydrate counting accuracy (total grams per meal, P=.008), reduced frequency of individual counting errors greater than 10 g (P=.047), and lower HbA1c levels (P=.03). Qualitative interviews and acceptability scale scores were positive. No major technical challenges were identified. Moreover, 43% (9/21) of iSpy participants were still engaged, with usage at least once every 2 weeks, at the end of the study. CONCLUSIONS: Our results provide evidence of efficacy and high acceptability of a novel carbohydrate counting app, supporting the advancement of digital health apps for diabetes care among youth with type 1 diabetes. Further testing is needed, but iSpy may be a useful adjunct to traditional diabetes management. TRIAL REGISTRATION: ClinicalTrials.gov NCT04354142; https://clinicaltrials.gov/ct2/show/NCT04354142.

BACKGROUND: Gender-incongruent (GI) youth have high rates of mental health problems. Although gender-affirming medical care (GAMC) provides psychological benefit, some GI youth present to care at older ages. Whether a relationship exists between age of presentation to GAMC and mental health difficulties warrants study. METHODS: A cross-sectional chart review of patients presenting to GAMC. Subjects were classified a priori as younger presenting youth (YPY) (<15 years of age at presentation) or older presenting youth (OPY) (≥15 years of age). Self-reported rates of mental health problems and medication use were compared between groups. Binary logistic regression analysis was used to identify determinants of mental health problems. Covariates included pubertal stage at presentation, social transition status, and assigned sex. RESULTS: Of 300 youth, there were 116 YPY and 184 OPY. After presentation, more OPY than YPY reported a diagnosis of depression (46% vs 30%), had self-harmed (40% vs 28%), had considered suicide (52% vs 40%), had attempted suicide (17% vs 9%), and required psychoactive medications (36% vs 23%), with all P < .05. After controlling for covariates, late puberty (Tanner stage 4 or 5) was associated with depressive disorders (odds ratio 5.49; 95% confidence interval [CI]: 1.14-26.32) and anxiety disorders (odds ratio 4.18 [95% CI: 1.22-14.49]), whereas older age remained associated only with psychoactive medication use (odd ratio 1.31 [95% CI: 1.05-1.63]). CONCLUSIONS: Late pubertal stage and older age are associated with worse mental health among GI youth presenting to GAMC, suggesting that this group may be particularly vulnerable and in need of appropriate care.

CONTEXT: Clinicians, researchers, and global health advocates often include pubertal development in outcomes. However, assessments of pubertal stage can be challenging because of the sensitive nature and feasibility of clinical examinations, especially in larger settings. OBJECTIVE: To determine the accuracy of self-assessed Tanner staging when compared with physically assessed Tanner stages by a clinician. DATA SOURCES: MEDLINE, PubMed, Embase, Web of Science, Scopus, the Cochrane Library, CINAHL. STUDY SELECTION: Studies were included if they reported 5â ×â 5 tables of self-assessment compared to clinician-assessment for the 5-stage Tanner scale. DATA EXTRACTION: We extracted data to generate complete 5â ×â 5 tables for each study, including any subgroup eligible for the analysis, such as overweight/obese youth. DATA SYNTHESIS: After screening, 22 studies representing 21,801 participants met our inclusion criteria for the meta-analysis. Overall agreement was moderate or substantial between the 2 assessments, with breast stage 1, female pubic hair 1, male pubic hair 1, and male pubic hair 5 having the highest agreement. When stages were collapsed into pre- (Tanner stage 1), in (stages 2,3), and completing (stages 4,5) puberty, levels of agreement improved, especially for pre- and completing pubertal development. Most included studies comprised Caucasian youth. More studies are needed which include a broader range of geographic and socioeconomic settings, as well as a greater diversity of racial/ethnic groups. CONCLUSIONS: Self-assessment of puberty is most accurate when identifying Tanner stage 1, Tanner stage 5 and when development is categorized into prepuberty, in, and completing puberty phases. Use of self-assessment data should be structured accordingly. PROTOCOL REGISTRATION: PROSPERO # CRD42018100205.

CONTEXT: Screening for and diagnosing non classic congenital adrenal hyperplasia (NCCAH) uses serum 17-hydroxyprogesterone (17OHP) thresholds established from immunoassay data; however, a new liquid-chromatography tandem mass spectrometry (LC-MS/MS) method results in lower 17OHP values. The evolution of immunoassays is also challenging our diagnostic cut-off for glucocorticoid insufficiency and few data re-evaluate the utility of testing for glucocorticoid insufficiency in NCCAH. OBJECTIVE: (1) Evaluate the 17OHP threshold that predicts NCCAH in children using LC-MS/MS, and (2) determine the prevalence of glucocorticoid insufficiency in NCCAH. METHODS: A retrospective chart review of pediatric patients who underwent ACTH stimulation tests with cortisol and 17OHP measurements from 2011 to 2018 for assessment of NCCAH. Other adrenal pathologies were excluded. A cortisol <â 415 nmol/L defined glucocorticoid insufficiency. Published correlation data determined a 17OHP of 3.3 nmol/L by LC-MS/MS was equivalent to 6 nmol/L by immunoassay. Data analysis was by measures of diagnostic accuracy. RESULTS: Of 188 patients included, 23 (12%) had NCCAH (21/23 had genetic confirmation); the remaining 2 had peak 17OHP >â 30 nmol/L. Baseline 17OHP ≥â 6 nmol/L most accurately screened for NCCAH-sensitivity and specificity 96%. Almost all genetically confirmed NCCAH (20/21) had peak 17OHP >â 30 nmol/L; all subjects with other diagnoses peaked <â 30 nmol/L. Glucocorticoid insufficiency was present in 55% with NCCAH. CONCLUSIONS: Despite the increased specificity of LC-MS/MS, a baseline 17OHP ≥â 6 nmol/L most accurately screened for NCCAH; this supports current practice guidelines. This threshold identified all with glucocorticoid insufficiency, notably prevalent in our cohort and for whom glucocorticoid stress dosing should be considered.
