Infertility risk assessment with ultrasound in congenital adrenal hyperplasia male patients.

Testicular adrenal rest tumor (TART) is a prevalent complication associated with congenital adrenal hyperplasia (CAH), culminating in gonadal dysfunction and infertility. Early hormonal intervention is preventive, but excessive glucocorticoid poses risks. Developing reliable methods for early TART diagnosis and monitoring is crucial. The present study aims to formulate a scoring system to identify high-risk infertility through analysis of TART ultrasound features. Grayscale and power Doppler ultrasound were employed in this retrospective study to evaluate testicular lesions in male CAH patients. Lesion assessment encompassed parameters such as range, echogenicity, and blood flow, and these were subsequently correlated with semen parameters. Results of 49 semen analyzes from 35 patients demonstrated a notable inverse correlation between lesion scores and both sperm concentration (rs = - 0.83, P < 0.001) and progressive motility (rs = - 0.56, P < 0.001). The ROC curve areas for evaluating oligospermia and asthenozoospermia were calculated as 0.94 and 0.72, respectively. Establishing a lesion score threshold of 6 revealed a sensitivity of 75.00% and specificity of 93.94% for oligospermia and a sensitivity of 53.85% and specificity of 100.00% for asthenozoospermia. These findings underscore the potential utility of incorporating ultrasound into routine CAH patient management, facilitating timely interventions to preserve male fertility.

Cross-Cultural Disparities in Psychosocial Research with Individuals with Classical Congenital Adrenal Hyperplasia: A Scoping Review.

INTRODUCTION: There are increased calls to address psychosocial needs among individuals with classical congenital adrenal hyperplasia (CAH). However, cross-cultural disparities exist in treatment practices and psychosocial outcomes that impact the generalizability of evidence-based recommendations. To date, this disparity has not been quantified. The present scoping review uses a dual approach to contrast rates of CAH diagnosis with CAH psychosocial research rates across countries. METHODS: Six electronic database searches were conducted for: (1) CAH incidence/birth/prevalence rates; and (2) psychosocial research with affected individuals and their families. Two authors reviewed each abstract for inclusion criteria. RESULTS: Sixty-eight and 93 full-text articles, respectively, were evaluated for incidence and country. The countries/regions with the highest reported CAH rates are Thailand, Ghana, and India. Those with the greatest portion of psychosocial publications are the USA, Germany, and the UK. CONCLUSION: A discrepancy exists between those countries with the highest CAH rates and those publishing psychosocial research. Specifically, increased rates of CAH are seen in non-Western countries/regions, whereas most psychosocial research arises out of Western Europe and the USA. Due to cultural differences between these regions, increased global collaboration is needed to both inform psychosocial research and translate findings in ways that are representative worldwide.

Quality of Life in Children and Young People With Congenital Adrenal Hyperplasia-UK Nationwide Multicenter Assessment.

CONTEXT: Quality of life (QoL) has been inconsistently reported in children and young people (CYP) with congenital adrenal hyperplasia (CAH). OBJECTIVE: Assess QoL in CYP with CAH in the UK alongside biometric and androgen profiles. DESIGN: To define the evidence base for health care delivery, we conducted a cross-sectional study in CYP with CAH in the UK. Questionnaire results were compared with normative data and between groups, and modelled for association with sex, height, weight, body mass index, or steroid biomarkers of CAH control. SETTING: Tertiary care in 14 UK centers. PATIENTS: Results from 104 patients, 55% female, mean age 12.7 years (SD 3.0), paired responses from parents. INTERVENTIONS: Strengths and Difficulties questionnaire (SDQ) and pediatric QoL questionnaire. MAIN OUTCOME MEASURE: Total QoL scores as assessed by SDQ and a pediatric QoL questionnaire in comparison to normative data. RESULTS: Total scores were worse in parents than normative data, but similar in patients. Patient QoL was rated better in social functioning but worse in emotional, school, and peer domains by patients, and worse in total scores and domains of peer problems, and psychosocial, emotional, and school functioning by parents. Parents consistently scored QoL of their children lower than their child. Larger height-SD score and lower weight-SD score were associated with better QoL. Girls with lower steroid biomarkers had worse SDQ scores. CONCLUSIONS: In CYP with CAH, reduced height, increased weight, and hormonal biomarkers consistent with overtreatment were associated with worse QoL; addressing these problems should be prioritized in clinical management.Clinical Trials Registration Number: SCH/15/088.

Assessment of the Degree of Clinical Suspicion of 21-Hydroxylase Deficiency Prior to the Newborn Screening Result.

The aim of the study was to analyze the clinical suspicion and where patients were when they received the positive result of the neonatal screening for CAH 21OHD. The present data derived from a retrospective analysis of a relatively large group of patients with classical CAH 21OHD patients nosed by newborn screening in Madrid, Spain. During the period from 1990 to 2015 of this study 46 children were diagnosed with classical 21OHD [36 with the salt-wasting (SW) form and 10 with simple virilizing (SV)]. In 38 patients, the disease had not been suspected before the neonatal screening result (30 SW and 8 SV). Thirty patients (79%) were at home without suspicion of any disease, as healthy children, 3 patients (8%) were at home pending completion of the study due to clinical suspicion of any disease (ambiguous genitalia, cryptorchidism) and 5 patients (13%) were admitted to the hospital for reasons unrelated to CAH (sepsis, jaundice, hypoglycemia). It is relevant to note that 69.4% of patients (25/36) with SW form were at home with potential risk of adrenal crisis. Six females had been incorrectly labeled as male at birth. The most frequent reason for clinical suspicion was genital ambiguity in women followed by family history of the disease. Neonatal screening provided better results than clinical suspicion. In the majority of patients with 21OHD the diagnosis by screening was anticipated to the clinical suspicion of the disease even in female patients with ambiguous genitalia.

Determinación de valores de corte de 17 hidroxiprogesterona ajustados por edad gestacional para la pesquisa neonatal de la hiperplasia suprarrenal congénita / Assessment of gestational age-adjusted 17-hydroxyprogesterone cut-off values for neonatal screening of congenital adrenal hyperplasia

La pesquisa neonatal de hiperplasia suprarrenal congénita se realiza mediante la determinación de 17 hidroxiprogesterona (17OHP) en gotas de sangre seca en papel de filtro. Los bebés prematuros presentan valores más elevados que los bebés de término, siendo de utilidad contar con límites de corte apropiados. Nuestro objetivo fue actualizar los valores de corte de 17OHP ajustados por edad gestacional para la metodología en uso a nivel nacional por las jurisdicciones asistidas por el "Programa Nacional de Fortalecimiento de la Detección Precoz de Enfermedades Congénitas". La 17OHP se determinó utilizando el kit comercial de enzimo-inmunoanálisis (ELISA competitivo), Elizen Neonatal 17OHP Screening (Zentech, Bélgica). Se obtuvieron límites de corte utilizando percentiles de la distribución de los valores de 17OHP para cada edad gestacional. La sensibilidad obtenida fue 100%, especificidad 98,76 %, tasa de falsos positivos 1,24 % y el valor predictivo positivo 1,12 %. Destacamos la importancia de disponer de límites de corte adecuados a la población. La armonización de los mismos permitirá resultados comparables entre los programas regionales de pesquisa neonatal (AU)

Newborn screening for congenital adrenal hyperplasia is performed by the measurement of 17-hydroxyprogesterone (17OHP) in dried blood spots on filter paper. Premature infants have higher values than full-term infants, and appropriate cutoff values are useful. Our aim was to update the cut-off values of 17OHP adjusted for gestational age for the methodology used at a national level in regions assisted by the "National Program for Strengthening the Early Detection of Congenital Diseases". 17OHP was determined using the commercial enzyme-linked immunosorbent assay (competitive ELISA) kit, Elizen Newborn 17OHP Screening (Zentech, Belgium). Cut-off values were obtained using percentiles of the distribution of 17OHP values for each gestational age. Sensitivity was 100%, specificity 98.76%, false positive rate 1.24%, and positive predictive value 1.12%. It is important to have cut-off values that are adjusted to the population. Harmonization will allow for the comparison of results among regional newborn screening programs (AU)

Cost-effective genotyping for classical congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) in resource-poor settings: multiplex ligation probe amplification (MLPA) with/without sequential next-generation sequencing (NGS).

PURPOSE: Genotyping of classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is becoming increasingly significant beyond prenatal counseling in the current era of emerging gene therapy/editing technologies. While the knowledge of common variants helps in designing cost-effective genotyping strategies, limited data are currently available from the Indian subcontinent, especially South India, mainly due to financial constraints. The aim of this study is to assess the genotype of individuals with classic CAH from a South Indian cohort in a cost-effective manner. METHODS: The genotypes of 46 unrelated subjects with classic CAH were studied through initial multiplex ligation-dependent probe amplification (MLPA) using the SALSA MLPA Probe-mix P050 CAH (MRC Holland). Next-generation sequencing (NGS) was done in 10 subjects, as their MLPA was either negative or showed heterozygous variants. RESULTS: The common variants observed in our study population of 46 subjects were large deletions (35.8%), intron 2 variant [c.293-13A/C > G] (35.8%), 8 bp del [c.332_339del p.(Gly111Valfs*21)] (7.7%), and R356W [c.1069 C > T p.(Arg357Trp)] (6.6%). MLPA alone detected pathogenic variants in 78.2% of the initial study samples (36/46). Sequential NGS resulted in a 100% detection rate in our study population. CONCLUSION: MLPA appears to be an effective first genotyping modality for this South Indian cohort due to the high prevalence of large deletions and common variants. MLPA as a first initial screening genotyping test with sequential NGS when required may be a cost-effective and highly sensitive approach to CYP21A2 genotyping in our part of the world and in resource-poor settings.

Caring for a Child with Congenital Adrenal Hyperplasia Diagnosed by Newborn Screening: Parental Health-Related Quality of Life, Coping Patterns, and Needs.

Diagnosing a child by newborn screening with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) causes multiple challenges for the affected parents and the whole family. We aimed to examine the health-related Quality of Life (HrQoL), coping, and needs of parents caring for a child with CAH to develop demand-responsive interventions for improving the psychosocial situation of affected families. In a retrospective cross-sectional design, we assessed HrQoL, coping patterns, and the needs of parents caring for a CAH-diagnosed child using specific questionnaires. Data of 59 families with at least one child diagnosed with CAH were analyzed. The results show that mothers and fathers in this study reached significantly higher HrQoL scores compared to reference cohorts. Decisive for the above-average parental HrQoL were effective coping behaviors and the parental needs being met. These findings verify the importance of helpful coping patterns and rapid fulfillment of parental needs for maintaining a good and stable HrQoL of parents with a child diagnosed with CAH. It is crucial to strengthen the parental HrQoL to build a reasonable basis for a healthy upbringing and improve the medical care of CAH-diagnosed children.

Why do parents recommend clitoral surgery? Parental perception of the necessity, benefit, and cost of early childhood clitoral surgery for congenital adrenal hyperplasia (CAH).

Historically, medical management of Congenital Adrenal Hyperplasia (CAH) in girls typically involved feminising surgery, which meant reducing the size and/or visibility of the enlarged clitoris. This practice may have become less routine but remains a common response to genital differences associated with CAH. Parents typically give permission for the child to undergo surgery in early childhood and recommend other parents facing a similar situation do the same. The current report is based on a qualitative content analysis of interviews with sixteen parents whose daughters with CAH had undergone one of two forms of clitoral surgery. We observed that: (i) some parents were initially unconcerned about their child's genital presentation; (ii) in general, clitoral surgery was considered as a readily available and natural response to the child's bodily difference; (iii) the parents acknowledged that there would be some risk but anticipated various benefits; and (iv) there was an absence of ethical considerations when the parents evaluated the various effects of surgery afterwards. We conclude from our analysis that parents of girls with CAH may not receive psychologically and ethically informed counselling to encourage critical reflections prior to authorizing genital surgery.

Increased Prevalence of Fractures in Congenital Adrenal Hyperplasia: A Swedish Population-based National Cohort Study.

CONTEXT: Low bone mineral density has been reported in individuals with congenital adrenal hyperplasia (CAH), but the prevalence of fractures is unclear. OBJECTIVE: To study the prevalence of fractures in CAH. DESIGN, SETTING, AND PARTICIPANTS: Patients with CAH (n = 714, all 21-hydroxylase deficiency) were compared with controls matched for sex and year and place of birth (n = 71 400). Data were derived by linking National Population-Based Registers. MAIN OUTCOME MEASURES: Number and type of fractures. RESULTS: Mean age was 29.8 ±â€…18.4 years. Individuals with CAH had more fractures compared to controls [23.5% vs 16.1%, odds ratio (OR) 1.61, 95% CI 1.35-1.91], and this was found in both sexes (females: 19.6% vs 13.3%, OR 1.57, 95% CI 1.23-2.02; males: 28.7% vs 19.6%, OR 1.65, 95% CI 1.29-2.12). Fractures were significantly increased in patients born before the introduction of neonatal screening but not in those born afterwards. Any major fracture associated with osteoporosis (spine, forearm, hip, or shoulder) was increased in all individuals with CAH (9.8% vs 7.5%, OR 1.34, 95% CI 1.05-1.72). The highest prevalence of fractures was seen in SV phenotype and I172N genotype while nonclassic phenotype and I2 splice genotype did not show increased prevalence. A transport accident as a car occupant and fall on the same level were more common in patients with CAH, both sexes, than in controls. CONCLUSIONS: Patients with CAH had an increased prevalence of both any fracture and fractures associated with osteoporosis (both sexes) but not for patients neonatally screened. We conclude that fracture risk assessment and glucocorticoid optimization should be performed regularly.

[Newborn screening for congenital hypothyroidism and congenital adrenal hyperplasia: Benefits and costs of a successful public health program]. / Dépistage néonatal de l'hypothyroïdie congénitale et de l'hyperplasie congénitale des surrénales - Bénéfices et coûts d'un programme de santé publique à succès.

Newborn screening is an important public health program and a triumph of preventive medicine. Economic analyses show that the benefits of newborn screening clearly outweigh the costs for certain diseases, but not necessarily for other ones. This is due to the great diversity of the natural history of the diseases detected, to the fact that each of these diseases considered individually is rare, and to differences in the effectiveness of interventions. In addition, the benefit-cost ratio of screening for a particular disorder may differ between countries, specifically between high-income and low- and middle-income countries. The burden of a disorder may also be alleviated by increased clinical awareness and effective clinical services, even in the absence of newborn screening. In this article, we focus on economic analyses of newborn screening for primary congenital hypothyroidism, which has been in place in high-income countries for roughly 40 years, and for classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Screening for the latter is not yet universal, even in high-income countries, although the lack of universal implementation may reflect factors other than economic considerations.

TITLE: Dépistage néonatal de l'hypothyroïdie congénitale et de l'hyperplasie congénitale des surrénales - Bénéfices et coûts d'un programme de santé publique à succès. ABSTRACT: Le dépistage néonatal est un important programme de santé publique et un triomphe de la médecine préventive. Les analyses économiques démontrent que les bienfaits de ce dépistage l'emportent sur les coûts pour certaines maladies, mais pas nécessairement pour toutes. Cela est dû à la grande diversité des maladies dépistées, au fait que chacune d'entre elles, considérée individuellement, est rare, et à des différences d'efficacité des interventions. En outre, le rapport entre les bénéfices et les coûts du dépistage d'une maladie donnée peut varier d'un pays à l'autre, en particulier entre les pays à revenus élevés et les pays à revenus faibles ou intermédiaires. Le fardeau d'une maladie peut être allégé, même en l'absence de dépistage néonatal, par une plus grande connaissance clinique et par des services cliniques efficients. Dans cet article, nous évaluons les arguments et les analyses économiques du dépistage de l'hypothyroïdie congénitale primaire, mis en place dans de nombreux pays depuis environ 40 ans, et celui de l'hyperplasie congénitale des surrénales due à une déficience en 21-hydroxylase. Le dépistage de cette dernière n'est pas encore universel, même dans les pays à revenus élevés, les décisions de sa mise en œuvre pouvant tenir compte de facteurs autres que des considérations économiques.

Assessment of medication adherence in children and adults with congenital adrenal hyperplasia and the impact of knowledge and self-management.

BACKGROUND: Congenital adrenal hyperplasia (CAH) is caused by a deficiency of one of the enzymes required for cortisol biosynthesis. The disease is classified as either classic (severe phenotype), subdivided into simple virilizing (SV) and salt-wasting (SW), or non-classic (NC) CAH. The treatment regime involves life-long glucocorticoid replacement, especially in classic phenotype. OBJECTIVES: We aimed to assess medication adherence, endocrine knowledge and self-management in patients with CAH and to compare patients' and physicians' assessments of medication adherence. METHODS: A prospective cross-sectional study of 108 patients with CAH (52 children and 56 adults) and 45 parents/caregivers. Two adherence measures were used, a self-reported questionnaire named Adherence Starts with Knowledge (ASK-12) with a cut-off level > 22 defined as poor adherence rate, and an assessment by a physician based on growth rate, 17-hydroxyprogesterone profile, and medical history, ranked using a five-point Likert scale. Measurements of the patients'/parents' knowledge and self-management were performed using Endocrine Society Clinical Practice Guidelines. RESULTS: Self-reported medication adherence was good with 74% of the participants reported good adherence with higher adherence in patients with the SW form. The highest endocrine knowledge and self-management were found in parents compared with children and adults with classic CAH. There was 30% discordance between the assessments by a physician and the self-reported ASK-12 scores independent of the severity of CAH. CONCLUSION: Patients and endocrinologists reported high medication adherence, however, discordance was found in 30% of the studied patients. Patients with the more severe form of CAH had higher adherence rates and demonstrated good endocrine knowledge/self-management.

Behavioral assessment of females with congenital adrenal hyperplasia.

PURPOSE: Patients with congenital adrenal hyperplasia (CAH) have an increased risk of psychological/psychiatric symptoms and disorders. This study aimed to assess the behavior of girls with CAH and its independent risk variables. METHODS: This cross-sectional study included 55 girls with CAH due to 21-hydroxylase deficiency (mean age 12.64 ± 1.52 years; salt-wasting (SW) form = 20, simple virilizing (SV) form = 35). Psychiatric interviewing and the Strength and Difficulties Questionnaire (SDQ) (parent-reporting questionnaires) were used to assess behavior. RESULTS: Compared to controls (n = 60), patients had a high total SDQ score (P = 0.001) and emotional, conduct, and hyperactivity-inattention symptoms, peer relationship problems (P = 0.001 for all), and prosocial behavior (p = 0.01) subscale scores, indicating externalizing and internalizing behavioral problems. Severe emotional symptoms and poor disease control were found with SW compared to the SV form. Multiple linear regression showed that bone age (BA) (ß = 0.331, t = 3.608; P = 0.001) and 17-OHP (ß = 0.408, t = 4.220; P = 0.001), testosterone (ß = 0.348, t = 3.220; P = 0.001), and androstenedione (ß = 0.238, t = 2.487; P = 0.015) levels were independently associated with behavioral problems. CONCLUSION: Females with CAH had frequent and severe behavioral symptoms. Excess androgenization, which was in part due to suboptimal steroid therapy, was the cause of the behavioral problems. Therefore, early optimization of CAH management should be stressed to prevent psychological consequences.

Assessment of Facial Morphologic Features in Patients With Congenital Adrenal Hyperplasia Using Deep Learning.

Importance: Congenital adrenal hyperplasia (CAH) is the most common primary adrenal insufficiency in children, involving excess androgens secondary to disrupted steroidogenesis as early as the seventh gestational week of life. Although structural brain abnormalities are seen in CAH, little is known about facial morphology. Objective: To investigate differences in facial morphologic features between patients with CAH and control individuals with use of machine learning. Design, Setting, and Participants: This cross-sectional study was performed at a pediatric tertiary center in Southern California, from November 2017 to December 2019. Patients younger than 30 years with a biochemical diagnosis of classical CAH due to 21-hydroxylase deficiency and otherwise healthy controls were recruited from the clinic, and face images were acquired. Additional controls were selected from public face image data sets. Main Outcomes and Measures: The main outcome was prediction of CAH, as performed by machine learning (linear discriminant analysis, random forests, deep neural networks). Handcrafted features and learned representations were studied for CAH score prediction, and deformation analysis of facial landmarks and regionwise analyses were performed. A 6-fold cross-validation strategy was used to avoid overfitting and bias. Results: The study included 102 patients with CAH (62 [60.8%] female; mean [SD] age, 11.6 [7.1] years) and 59 controls (30 [50.8%] female; mean [SD] age, 9.0 [5.2] years) from the clinic and 85 controls (48 [60%] female; age, <29 years) from face databases. With use of deep neural networks, a mean (SD) AUC of 92% (3%) was found for accurately predicting CAH over 6 folds. With use of classical machine learning and handcrafted facial features, mean (SD) AUCs of 86% (5%) in linear discriminant analysis and 83% (3%) in random forests were obtained for predicting CAH over 6 folds. There was a deviation of facial features between groups using deformation fields generated from facial landmark templates. Regionwise analysis and class activation maps (deep learning of regions) revealed that the nose and upper face were most contributory (mean [SD] AUC: 69% [17%] and 71% [13%], respectively). Conclusions and Relevance: The findings suggest that facial morphologic features in patients with CAH is distinct and that deep learning can discover subtle facial features to predict CAH. Longitudinal study of facial morphology as a phenotypic biomarker may help expand understanding of adverse lifespan outcomes for patients with CAH.

Assessment of the most common CYP21A2 point mutations in a cohort of congenital adrenal hyperplasia patients from Egypt.

Objectives Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is a common autosomal recessive disorder caused by defects in the CYP21A2 gene. We aimed to determine the prevalence of the most commonly reported mutations among 21-OHD Egyptian patients and correlate genotype with phenotype. Methods Molecular analysis of the CYP21A2 gene was performed for the detection of the six most common point mutations (p.P30L, p.I172N, p.V281L, p.Q318X, the splice site mutation Int2 [IVS2-13A/C>G], and the cluster of three mutations [p.I236N, p.V237E, and p.M239K] designed as CL6). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was performed on 47 unrelated Egyptian 21α-OH deficiency patients and their available parents to detect the presence of the six most common point mutations. Results Screening for the six most common point mutations in CYP21A2 gene, revealed mutations in 87.2% (82/94) of the studied alleles corresponding to 47 Egyptian patients. The most common mutation among the studied cases was IVS2-13C/A>G that was found to be presented in a frequency of 46.8% (44/94). The genotype/phenotype correlations related to null, A, and B groups were with PPV of 100, 55.5, and 83.3%, respectively. Conclusions The described method diagnosed CAH in 80.8% of the studied patients. Good correlation between genotype and phenotype in salt wasting and simple virilizing forms is determined, whereas little concordance is seen in nonclassical one. Furthermore, studying the carrier frequency of 21-OHD among the normal population is of great importance.

Clinical Impact and Cost Efficacy of Newborn Screening for Congenital Adrenal Hyperplasia.

OBJECTIVES: To evaluate the clinical impact of a congenital adrenal hyperplasia (CAH) newborn screening program and incremental costs relative to benefits in screened vs unscreened infants. We hypothesized that screening would lead to clinical benefits and would be cost effective. STUDY DESIGN: This was an ambispective cohort study at British Columbia Children's Hospital, including infants diagnosed with CAH from 1988-2008 and 2010-2018. Data were collected retrospectively (unscreened cohort) and prospectively (screened cohort). Outcome measures included hospitalization, medical transport, and resuscitation requirements. The economic analysis was performed using a public payer perspective. RESULTS: Forty unscreened and 17 screened infants were diagnosed with CAH (47% vs 53% male). Median days to positive screen was 6 and age at diagnosis was 5 days (range, 0-30 days) and 6 days (range, 0-13 days) in unscreened and screened populations, respectively. In unscreened newborns, 55% required transport to a tertiary care hospital, 85% required hospitalization, and 35% required a fluid bolus compared with 29%, 29%, and 12% in screened infants, respectively. The cost of care was $33 770 per case in unscreened vs $17 726 in screened newborns. In the screened cohort, the incremental cost-effectiveness ratio was $290 in the best case analysis and $4786 in the base case analysis, per hospital day avoided. CONCLUSIONS: Compared with unscreened newborns, those screened for CAH were less likely to require medical transport and had shorter hospital stays. Screening led to a decrease in hospitalization costs. Although screening did not result in cost savings, it was assessed to be cost effective considering the clinical benefits and incremental cost-effectiveness ratio.

Assessment of health-related quality of life in Egyptian children and adolescents with congenital adrenal hyperplasia.

Background Congenital adrenal hyperplasia (CAH) is a chronic disorder causing adrenal insufficiency and hyperandrogenism affecting the quality of life (QOL). The objective of the study was to assess the health-related QOL (HRQOL) in Egyptian children and adolescents with CAH and to identify factors affecting it. Methods This cross-sectional study included 200 CAH patients (with 21-hydroxylase deficiency [21-OHD]) who were assessed according to their age, sex, clinical phenotype, timing of genitoplasty, hospital admissions within the last year, compliance to treatment, regularity of follow-up, presence of complications and hormonal control. HRQOL was assessed using the World Health Organization (WHO)QOL-BREF questionnaire with four domains analyzed independently including physical, psychological, social and environmental domains, with higher scores indicating better QOL. Results The study included 140 females and 60 males with a mean age of 6.6 ± 4.5 years, and 88% were salt-wasting (SW). Older patients had significantly lower QOL scores (r = - 0.151, p = 0.033). The physical domain correlated significantly with the degree of virilization (r = - 0.491, p = 0.001) and frequency of hospitalization (r = - 0.495, p < 0.001). The psychological domain was affected by age (r = - 0.157, p = 0.026) and timing of genitoplasty (r = - 0.326, p = 0.001), while the social domain was affected by age (r = -0.277, p < 0.005) and pubertal stage (r = - 0.195, p = 0.006). Females had lower scores at the psychological domain (p < 0.001), whereas males had lower scores at the physical domain (p = 0.003). Salt-losing patients had lower scores at the physical domain (p = 0.001). Patients with good hormonal control had higher scores at the physical domain (p = 0.03). Genitoplasty affected both psychological and social domains (p = 0.003 and 0.01, respectively). Patients with hypertension and hirsutism had lower QOL scores (p < 0.05). Conclusions HRQOL was relatively more affected in CAH patients with older age, poor hormonal control, high frequency of hospital admissions and those who developed complications.

ENERGY EXPENDITURE IN 21-HYDROXYLASE CONGENITAL ADRENAL HYPERPLASIA PATIENTS AND COMPARISON WITH PREDICTIVE EQUATIONS.

Objective: To characterize resting energy expenditure (REE) in patients with classic 21-hydroxylase congenital adrenal hyperplasia (21-OH CAH) using indirect calorimetry and compare it to the most commonly used REE predictive equations. Methods: This case-control study comprised 29 post-pubertal 21-OH CAH patients regularly followed at the University of Campinas. Elevated serum 17-hydroxyprogesterone and CYP21 gene molecular analysis confirmed the diagnosis. A healthy control group paired by age, gender, and body mass index was examined. Dual-energy X-ray absorptiometry (DEXA) measured body compositions. A bioimpedance analyzer determined fat-free mass, and indirect calorimetry using a metabolic cart measured REE. Results: Unlike our initial hypothesis, REE was similar between the groups (18.7 ± 3.1 kcal/kg/day in CAH vs. 20.3 ± 3.5 kcal/kg/day in controls; P = .728). No predictive equations reached the stipulated accuracy criteria, thus lacking validity in REE assessment in adults with the characteristics of the group studied. DEXA analysis revealed higher body fat and diminished nonbone lean mass in 21-OH CAH. Anthropometric and bioelectrical impedance parameters were not significantly different. Conclusion: Classic 21-OH CAH is generally followed in reference centers, which may facilitate indirect calorimetry use for REE measurement. Alternatively, considering our REE findings in adult 21-OH CAH patients, nutrition management based on 25 kcal/body weight/day (measured REE × activity factor 1.2 to 1.3) may be reasonable for current body weight maintenance in these patients. Abbreviations: 17-OHP = 17-hydroxyprogesterone; 21-OH CAH = classic 21-hydroxylase deficiency congenital adrenal hyperplasia; BMI = body mass index; REE = resting energy expenditure; VO2 = volume of oxygen; VCO2 = volume of carbon dioxide.

Assessment of retinal thickness as a marker of brain masculinization in children with congenital adrenal hyperplasia: a pilot study.

Objective To investigate the relationship between brain masculinization and retinal thickness in children with congenital adrenal hyperplasia (CAH). Methods Forty-five patients with CAH aged between 4 and 18 years and 30 age-matched healthy controls were included in this prospective study. Macular area was examined with optical coherence tomography (OCT); central subfield thickness (CST), cube volume (CV) and macular retinal thickness (MT) were measured in each subject. A gender identity questionnaire (GIQ) was used for the evaluation of gender happiness index. Results Girls with CAH had a higher CV (p = 0.002) and MT (p = 0.003) than healthy girls. No significant difference was found between boys with CAH and healthy boys regarding the retinal thickness measurements. Mean CST, CV and MT were significantly higher in boys than in girls in the control group (p = 0.013, p < 0.001, respectively), but there was no significant difference in those parameters between girls and boys with CAH. The gender happiness index was not different between healthy boys and boys with CAH, but was significantly lower in girls with CAH than healthy girls (p = 0.01). Conclusions As retina is part of the brain, our finding appears to be a morphological evidence of the excess androgen exposure on brain structures in girls with CAH. In addition, we suggest using retinal thickness measurements as a marker of prenatal excess androgen exposure in future studies.

Initial assessment of a child with suspected disorder of sex development.

Disorders of sex development (DSD) are defined as discrepancy between chromosomal, gonadal and anatomic sex. The basic principles for the management of DSD include a multidisciplinary approach for gender assignment. Clinical assessment includes a detailed history and examination of external genitalia. Most of the disorders with symmetrical gonades indicate hormonal cause while asymmetrical gonades are found in chromosomal DSDs. Karyotyping will indicate a 46XX DSD, 46 XY DSD or mosicism. Internal anatomy is defined by ultrasonography, genitoscopy and laparoscopy. Human chorionic gonadotrophins (hCG) stimulation test is carried out in under-virilised males to see the function of Leydig cells in testes. The Most common cause of 46XX DSD is congenital adrenal hyperplasia (CAH). The decision of gender assignment surgery is to be taken in a multidisciplinary environment and with informed consent of the parents. Most of 46 XX CAH patients, even if markedly virilised, and 46 XY complete androgen insensitivity syndrome are raised as females. Similarly, most of 5-α reductase deficiency and 17-ß hydroxysteroid dehydrogenase deficiency patients are assigned to the male gender. The decision in cases of mixed gondal dysgenesis and ovotesticular DSD is based on the development of external and internal genitalia. Patients with androgen biosynthetic defects, partial androgen insensitivity syndrome are usually assigned to the male gender.
