Higher Body Fat but Similar Phase Angle Values in Patients with the Classical Form of Congenital Adrenal Hyperplasia in Comparison to a Control Group. Nutrients 2022; 14:nu14235184. [PMID: 36501213 PMCID: PMC9739276 DOI: 10.3390/nu14235184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 11/28/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022] Open
Abstract
This study aimed to compare phase angle (PhA) and bioelectrical impedance vector analysis (BIVA) values between adult patients with congenital adrenal hyperplasia caused by 21-hydroxylase deficiency (CAH21OHD) and a control group. A total of 22 patients (15 women, 22.9 ± 3.7 years) were compared with 17 controls (11 women, 27.0 ± 2.5 years). Body composition was determined by dual-energy X-ray absorptiometry. Bioelectrical impedance was used to calculate PhA, and BIVA was performed using specific software. Student’s t-test and analysis of covariance were used to compare groups. Hedges’ G and partial n2 were calculated for the effect estimates. Hotelling’s t2 test was used to compare the mean impedance vectors between the groups. The Mahalanobis test was used to determine the distance between confidence ellipses. Patients with CAH21OHD had a higher fat mass percentage than that of the control group (both sexes). There was no significant difference in PhA values between groups (CAH21OHD vs. control) in females (6.9° vs. 6.3°, p = 0.092) and males (8.2° vs. 8.1°, p = 0.849), after adjusting for covariates (age and height). BIVA analysis showed a significant difference in the mean impedance vectors between the female groups (T2 = 15.9, D = 1.58, p = 0.003) owing to the higher reactance/height (Δ = 8.5; p < 0.001) of the patients. The PhA did not significantly differ between the groups. Female patients had significantly higher reactance values. However, further studies are needed to determine the usefulness of bioimpedance parameters in evaluating the hydration status and cellular integrity of patients with CAH21OHD.

Abstract
OBJECTIVE To assess the current medical practice in Europe regarding prenatal dexamethasone (Pdex) treatment of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. DESIGN AND METHODS A questionnaire was designed and distributed, including 17 questions collecting quantitative and qualitative data. Thirty-six medical centres from 14 European countries responded and 30 out of 36 centres were reference centres of the European Reference Network on Rare Endocrine Conditions, EndoERN. RESULTS Pdex treatment is currently provided by 36% of the surveyed centres. The treatment is initiated by different specialties, that is paediatricians, endocrinologists, gynaecologists or geneticists. Regarding the starting point of Pdex, 23% stated to initiate therapy at 4-5 weeks postconception (wpc), 31% at 6 wpc and 46 % as early as pregnancy is confirmed and before 7 wpc at the latest. A dose of 20 µg/kg/day is used. Dose distribution among the centres varies from once to thrice daily. Prenatal diagnostics for treated cases are conducted in 72% of the responding centres. Cases treated per country and year vary between 0.5 and 8.25. Registries for long-term follow-up are only available at 46% of the centres that are using Pdex treatment. National registries are only available in Sweden and France. CONCLUSIONS This study reveals a high international variability and discrepancy in the use of Pdex treatment across Europe. It highlights the importance of a European cooperation initiative for a joint international prospective trial to establish evidence-based guidelines on prenatal diagnostics, treatment and follow-up of pregnancies at risk for CAH.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders that occur due to defects in the steroidogenesis pathway. Approximately 90% of CAH cases can be diagnosed by the measurement of serum 17-hydroxyprogesterone alone. However, the quantification of six additional steroids could significantly improve CAH laboratory diagnosis. Using dried blood spot (DBS) as specimen of choice can further improve patient care due to the small sample volume required for CAH diagnosis in neonates. METHODS An optimized DBS sample preparation method was employed for steroids quantification without the need of derivatization. A LC-MS/MS assay was developed and optimized using a reverse phase-ultra high-pressure liquid chromatography (RP-UHPLC) system combined with triple quadrupole mass spectrometry using positive electrospray ionization mode. RESULTS The assay was validated according to CLSI analytical guidelines, including lower limit of quantification (LLOQ), linearity, precision, accuracy, carryover, and method comparison. The analytical measuring range of the method for all steroids was 2.5, 5, or 10 ng/ml to 250 ng/ml in DBS, r2 ≥ 0.995. The LLOQ, intra-day and inter-day precision were 0.11-1.8 ng/ml, 1.2-6.4 ng/ml, 1.8-11.5%, and 5.3-13.8%, respectively. CONCLUSIONS Our LC-MS/MS assay simultaneously detects 7 steroids for the diagnosis of CAH and can be readily implemented in clinical laboratories to provide superior analytical performance over traditional immunoassays.

Abstract
BACKGROUND Patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH21OHD) have increased fat mass and metabolic alterations. The bioelectrical impedance phase angle (PhA) is an indicator of cellular integrity in several diseases. This study aimed to determine the influence of adiposity levels, sex, CAH21OHD, pubertal development, body composition, and treatment on the PhA of patients with CAH21OHD. METHODS Forty girls and 30 boys with CAH21OHD aged 15.3 ± 5.8 years were evaluated. Sexual maturation was assessed by a pediatrician. The PhA was assessed using bioelectrical impedance, percentage of fat mass (% FM), and lean soft tissue (LST) with dual-energy X-ray absorptiometry. Adiposity levels were compared using % FM tertiles and body mass index (BMI). Glucocorticoid dosage was converted using hydrocortisone dose equivalent (HDE). RESULTS No differences were found in the PhA values among the clinical form (p = 0.103), BMI (p = 0.498), and % FM (p = 0.654) groups. High PhA values were observed in boys (p = 0.011) and postpubertal (p < 0.001) patients. LST, HDE, and height in girls (r2 = 0.68, p < 0.001) and age, HDE, and FM in boys (r2 = 0.82, p < 0.001) determined the PhA variations. BMI explained 14% (p = 0.032) of the PhA variations, whereas LST, height, HDE, and FM (kg) explained 66% (p < 0.001) in the prepubertal, pubertal, and postpubertal groups, respectively. CONCLUSION LST determined the PhA variations in girls and the postpubertal group. Age and BMI were determinants in boys and the pre- and pubertal groups, respectively.

Abstract
Adrenal-derived glucocorticoids mediate the physiological response to stress. Chronic disturbances in glucocorticoid homeostasis, i.e. in Addison's and Cushing's disease patients, predispose to the development of atherosclerotic cardiovascular disease. Here we review preclinical and clinical findings regarding the relation between changes in plasma glucocorticoid levels and the atherosclerosis extent. It appears that, although the altered glucocorticoid function can in most cases be restored in the different patient groups, current therapies do not necessarily reverse the associated risk for atherosclerotic cardiovascular disease. In our opinion much attention should therefore be given to the development of a Cushing's disease mouse model that can (1) effectively replicate the effect of hypercortisolemia on atherosclerosis outcome observed in humans and (2) be used to investigate, in a preclinical setting, the relative impact on atherosclerosis susceptibility of already available (e.g. metyrapone) and potentially novel (i.e. SR-BI activity modulators) therapeutic agents that target the adrenal glucocorticoid output.

Abstract
PURPOSE Testicular adrenal rests tumor (TART) is a rare kind of benign tumor in the testis. It usually occurred secondary to congenital adrenal hyperplasia (CAH), a hormonal disorder caused by hydroxylase deficiency. As the first-line examination method, ultrasound provides crucial diagnostic information for TART, although misdiagnosis to malignancy is quite common because of its rare prevalence. We aimed to summarize the sonographic manifestations of TART to improve the diagnostic accuracy and specificity. METHODS Eight CAH patients with TART identified by ultrasound in our medical center were retrospectively reviewed. Clinical and hormonal profile, semen analysis and treatment choices were collected. Sonographic examinations were performed at the first evaluation and interpreted by experienced radiologists individually. All patients received regular follow-up, and 5 patients undertook repeated scrotal ultrasound. A literature review of TART in CAH patients was conducted, with 123 patients from 23 articles since 1990 included. RESULTS A total of 8 patients aged between 4 to 27 years old were enrolled. 7 of 8 (87.5%) patients exhibited bilateral testicular lesions. The sizes of the testicular lesions were between 0.18 ml to 5.68 ml, and all showed a clear boundary. 10/15 (66.7%) lesions were homogenously hypoechoic, 4/15 (26.7%) were heterogeneously iso-hypoechoic, and 1/15 (6.7%) were homogenously isoechoic. 10/15 (66.7%) lesions were hyper-vascular. The longitudinal follow-up of 5 patients showed testicular lesions changed in terms of size, echogenicity, and vascularity after steroid treatment. A potential correlation may exist between ACTH levels and tumor size (p = 0.066). From the literature review, 100/123 (81%) patients got bilateral lesions, and 95% of them were located near the mediastinum. 80/103 (78%) lesions exhibited a clear boundary, and predominant lesions (74%) were hypoechogenic. Vascularity was with great diversity. Seventy-nine lesions of 44 patients were followed-up by scrotal ultrasound, among which 29 (37%) remained unchanged, 29(37%) shrank, and 21(27%) disappeared. CONCLUSIONS Key sonographic characteristics of TART are: resembled lesions on both testes, located near the mediastinum, clear boundary, and changed in size or echogenicity after steroid treatment. These features can help radiologists to make an accurate diagnosis of TART.

Abstract
Androgen excess (hyperandrogenism) is a common endocrine disorder affecting women of reproductive age. The potential causes of androgen excess in women include polycystic ovary syndrome, congenital adrenal hyperplasia (CAH), adrenal tumors, and racial disparity among many others. During pregnancy, luteoma, placental aromatase deficiency, and fetal CAH are additional causes of gestational hyperandrogenism. The present report reviews the various phenotypes of hyperandrogenism during pregnancy and its origin, pathophysiology, and the effect of hyperandrogenism on the fetal developmental trajectory and offspring consequences.

Abstract
BACKGROUND The objective of the study was to describe the prevalence, clinical characteristics and aetiological diagnosis in children with disorders of sex development (DSDs) presenting to a tertiary referral centre. METHODS This is a retrospective review of all cases of DSD referred to the Paediatric Endocrine Unit in Inkosi Albert Luthuli Central Hospital (IALCH) from January 1995 to December 2014. RESULTS A total of 416 children (15.1%; CI: 13.8%-16.5%) were diagnosed with DSD. The aetiological diagnosis based on the current classification [Lawson Wilkins Paediatric Endocrine Society (LWPES) and European Society for Paediatric Endocrinology (ESPE)] was sex chromosome DSD in 9.5% (n=33), 46 XX DSD in 33% (n=114) and 46 XY DSD in 57.5% (n=199). The most common diagnoses in descending order were a disorder in androgen synthesis and action (not classified) in 53% (n=182), ovotesticular DSD in 22% (n=75) and congenital adrenal hyperplasia (CAH) in 10% (n=36). Overall the median age of presentation was 10 months (IQR: 1 month-4.5 years). There was a significant relationship (p<0.001) between the age of presentation and aetiological diagnosis. The majority (97%) of African patients had a diagnosis of 46 XX DSD. Prematurity was present in 47% (n=83) of children with 46 XY DSD (p<0.001). CONCLUSIONS DSD is not an uncommon diagnosis in African patients in sub-Saharan Africa. The most common aetiological diagnosis is 46 XY DSD in androgen synthesis and action, followed by ovotesticular DSD. CAH is only the third most common disorder.

Abstract
PURPOSE Steroid 21-hydroxylase deficiency (21-OHD) is the common type of congenital adrenal hyperplasia (CAH) caused by defects in the CYP21A2 gene, as an autosomal recessive disease, genetic analysis has a prominent role in its diagnosis. Our objectives were to determine the prevalence of common mutations in a group of Egyptian patients with 21-OHD and their families using rapid methods, and also to detect the rate of deletion, duplication and conversions in CYP21A2 gene. METHODS Rapid detection methods were used: allele-specific PCR for c.293-13A>G (g.659A>G), c.518T>A (p.I172N) variants and c.332_339del (8-bp deletion in exon 3), and real-time, quantitative PCR assay was used to detect deletion in the CYP21A2 gene. 29 Egyptian patients, 38 family members, and 20 healthy controls were all included in the study. RESULTS The frequency of c.293-13A>G splice mutation was reported in 96.6 % cases, G allele had 2.5-folds higher risk to develop CAH than other alleles. The c.518T>A mutation was reported in 69 % cases, children carrying the mutant allele were 2.1 times more risk. The most frequent combined mutations detected were c.293-13A/C>G/c.518T>A in 58.6 % cases. CONCLUSION The genetic analysis of the splice site mutation c.293-13A>G and c.518T>A variant can be used as good biomarkers for early detection of cases and carriers in 21-OHD CAH Egyptian children, since the methods used have rapid turnaround time.

Abstract
A 79-year-old woman, presented with increased hair growth in the chin and the upper lip but no in other androgen-dependent areas of her body. Hormonal evaluation showed markedly elevated serum testosterone level (>1.7 ng/ml) and normal DHEA-S, androstenedione, 17-hydroxyprogesterone, cortisol and TSH levels. The diagnosis of probable pure testosterone secreting tumor was made. Transvaginal ultrasound and magnetic resonance image revealed a 16 mm × 12 mm nodular formation indicative of an atypical adenoma in the left adrenal gland and a tube-shaped, fluid-filled, thin-walled image measuring 28 mm × 14 mm suggestive of a hydrosalpinx in the right ovary. Differential diagnosis between the coexistence of an androgen-producing ovarian tumor (occult) associated with a finding of an adrenal image (Incidentaloma) or an adrenal tumor secreting testosterone only was done. Since cortisol levels went down, but total testosterone inhibition did not occur after suppression with dexamethasone. An ovarian androgen secreting tumour was suspected and surgery was performed. Histological examination showed a Leydig cells hyperplasia. After the operation testosterone returned to normal with regression of clinical symptoms.

Abstract
AIMS to confirm the diagnosis of 21-hydroxylase deficiency (21-OHD) by the analysis of CYP21A2 gene in infants with clinical and/or biochemical features of 21-OHD in order to clarify which patients to submit to genetic analysis; to analyze the genotype-phenotype concordance in these infants. SUBJECTS AND METHODS We studied 25 children with clinical and/or biochemical features of 21-OHD. All of them and their parents were submitted to genetic analysis of CYP21A2. Patients were classified in 3 groups according to mutations' severity: severe (group A), moderate (group B) or mild (group C). RESULTS CYP21A2 gene mutations were found in 17 children. Whereas all infants of groups A and B presented a classical form of 21- OHD, children of group C had a non-classical form of 21-OHD. Four infants resulted heterozygotes and 4 children were wildtype. A girl clinically presenting a non-classical form of 21-OHD resulted compound heterozygote with one of the mutations not described in literature (R25W) and whose residual enzymatic activity is not already known. All affected children presented a 17-OHP level after ACTH stimulation greater than 100 nmol/l. We found an optimal concordance between 17-OHP levels after ACTH test and genotype. CONCLUSIONS CYP21A2 analysis permitted to confirm the diagnosis of 21-OHD in 68% of our children. To improve this percentage we suggest to perform the CYP21A2 analysis only when 17-OHP after ACTH test is greater than 100 nmol/l. Moreover, we found an optimal genotype-phenotype concordance in the 21-OHD patients.

Abstract
OBJECTIVE: The purpose of this study was to identify factors that might interfere with reaching the final height in patients with 21-hydroxylase deficiency (21-OHD). SUBJECTS AND METHODS: Thirty-one patients with classical 21-OHD who reached their FH in our Institution were evaluated in order to compare the Z score for final height (FHZ) with: (1) the target height, (2) the standard height for the population, and (3) the hydrocortisone treatment schedule. RESULTS: The FHZ of -2.13 ± 1.11 had a significant negative correlation with the hydrocortisone doses used throughout the period of study. Patients who reached FH within the normal population range were those who received lower doses of hydrocortisone, as compared to those whose FH remained below -2 SDS. CONCLUSION: We conclude that careful treatment adjustments have a major influence on growth of children with CAH, and that the dose range for hydrocortisone replacement that does not lead to side effects is relatively narrow. The better height outcome was achieved in 21-OHD patients who received lower doses of hydrocortisone.

Abstract
Congenital adrenal hyperplasia consists of a heterogenous group of inherited disorders
due to enzymatic defects in the biosynthetic pathway of cortisol and/or aldosterone. This
results in glucocorticoid deficiency, mineralocorticoid deficiency, and androgen excess.
95% of CAH cases are due to 21-hydroxylase deficiency. Clinical forms range from the
severe, classical CAH associated with complete loss of enzyme function, to milder,
non-classical forms (NCAH). Androgen excess affects the pilosebaceous unit, causing
cutaneous manifestations such as acne, androgenetic alopecia and hirsutism. Clinical
differential diagnosis between NCAH and polycystic ovary syndrome may be difficult. In
this review, the evaluation of patients with suspected CAH, the clinical presentation of
CAH forms, with emphasis on the cutaneous manifestations of the disease, and available
treatment options, will be discussed.

Abstract
There is considerable controversy about the origins of sex differences in cognitive abilities, particularly the male superiority in spatial abilities. We studied effects of early androgens on spatial and mechanical abilities in adolescents and young adults with congenital adrenal hyperplasia (CAH). On tests of three-dimensional mental rotations, geography, and mechanical knowledge, females with CAH scored higher than their unaffected sisters, and males with CAH scored lower than their unaffected brothers. Exploratory regression analyses suggest that androgens affect spatial ability in females directly and through male-typed activity interests. Findings indicate that early androgens influence spatial and mechanical abilities, and that androgen effects on abilities may occur in part through effects on sex-typed activity interests.

Abstract
There is considerable interest in understanding women's underrepresentation in science, technology, engineering, and mathematics careers. Career choices have been shown to be driven in part by interests, and gender differences in those interests have generally been considered to result from socialization. We explored the contribution of sex hormones to career-related interests, in particular studying whether prenatal androgens affect interests through psychological orientation to Things versus People. We examined this question in individuals with congenital adrenal hyperplasia (CAH), who have atypical exposure to androgens early in development, and their unaffected siblings (total N=125 aged 9 to 26 years). Females with CAH had more interest in Things versus People than did unaffected females, and variations among females with CAH reflected variations in their degree of androgen exposure. Results provide strong support for hormonal influences on interest in occupations characterized by working with Things versus People.

Abstract
CONTEXT Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH) because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH), luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.

Abstract
Interest in biological substrates of sex-related variations in psychological and physiological characteristics has led to a search for biomarkers of prenatal hormone exposure that can be measured postnatally. There has been particular interest in digit ratio, the relative lengths of the second and fourth fingers (2D:4D), but its validity as a measure of prenatal androgen has not been established. We report the strongest evaluation of the value of 2D:4D as a biomarker for early androgen exposure. Individuals with 46,XY karyotype but no effective prenatal androgen exposure due to complete androgen insensitivity syndrome had digit ratios that were feminized: they were higher than those of typical men and similar to those of typical women. Nevertheless, the effect was modest in size, and there was considerable within-group variability and between-group overlap, indicating that digit ratio is not a good marker of individual differences in prenatal androgen exposure.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) due 21-hydroxylase deficiency (21-OHD) is a common autosomal recessive disorder. It is caused by defects in the CYP21A2 gene. OBJECTIVE Our aim was to determine the frequency of common gene mutations and to evaluate genotype-phenotype correlations in Turkish 21-OHD patients. METHODS Molecular analysis of the CYP21A2 gene was performed for the detection of the eight most common point mutations [p.P30L, IVS2-13C>G (IVS-2), p.I172N, exon 6 mutation cluster (p.I236N, p.V237E, p.M239K), p.V281L, p.Q318X, p.R356W, 8-bp-deletion], of large deletion and conversion by southern blotting, allele specific semi-quantitative PCR/enzyme restriction method and sequencing, in 56 patients with 21-OHD, from 52 families. RESULTS Disease-causing mutations were identified in 77 out of 91 alleles (84.6%) of the patients. Mutations were found in 34 of 43 alleles (79.1%) in salt wasting (SW; n=26), 32 of 36 alleles (88.8%) in simple virilizing (SV; n=24) and 11 of 12 alleles (91.6%) in non-classical (NC; n=6) form of CAH. The most frequent mutations were IVS-2 (22.0%), large conversion (14.3%), p.I172N (9.9%) p.R356W (8.8%), and large deletion (6.6%). In the SW form, the most frequent genotypes were homozygous for IVS-2 (11.5%) and homozygous for large conversion of the gene (11.5%). In the SV form, the most frequent genotype was homozygous for IVS-2 (20%), followed by compound heterozygous for p.I172N/8-bp del (10%). Homozygous for p.V281L (16.7%) was most common in NC. In most cases there was good correlation between genotype and phenotype. In the SW and NC forms, genotypes of all the patients correlated with their phenotypes. CONCLUSIONS This is the first comprehensive study on the molecular basis of CAH patients in the Turkish population. Based on these results, we propose a modified screening strategy to facilitate molecular testing of CAH patients in our population.

Abstract
Human steroid 21-hydroxylase (CYP21) and steroid 17alpha-hydroxylase/17,20-lyase (CYP17) are two closely related cytochrome P450 enzymes involved in the steroidogenesis of glucocorticoids, mineralocorticoids, and sex hormones, respectively. Compounds that inhibit CYP17 activity are of pharmacological interest as they could be used for the treatment of prostate cancer. However, in many cases little is known about a possible co-inhibition of CYP21 activity by CYP17 inhibitors, which would greatly reduce their pharmacological value. We have previously shown that fission yeast strains expressing mammalian cytochrome P450 steroid hydroxylases are suitable systems for whole-cell conversion of steroids and may be used for biotechnological applications or for screening of inhibitors. In this study, we developed a very simple and fast method for the determination of enzyme inhibition using Schizosaccharomyces pombe strains that functionally express either human CYP17 or CYP21. Using this system we tested several compounds of different structural classes with known CYP17 inhibitory potency (i.e. Sa 40, YZ5ay, BW33, and ketoconazole) and determined IC50 values that were about one order of magnitude higher in comparison to data previously reported using human testes microsomes. One compound, YZ5ay, was found to be a moderate CYP21 inhibitor with an IC50 value of 15 microM, which is about eight-fold higher than the value determined for CYP17 inhibition (1.8 microM) in fission yeast. We conclude that, in principle, co-inhibition of CYP21 by CYP17 inhibitors cannot be ruled out.

Abstract
Experimental studies in animals indicate that androgen exposure in fetal or neonatal life largely accounts for known sex differences in brain structure and behavior. Clinical research in humans suggests similar influences of early androgen concentrations on some behaviors that show sex differences, including play behavior in childhood and sexual orientation in adulthood. Available research also suggests that sex steroid hormone exposure may contribute to sex differences in the risk of autism and affective disorders in schizophrenia. However, findings have been inconsistent for other characteristics that show sex differences, including aggression and spatial ability. Moreover, social and environmental factors may modulate some of the associations observed. This article reviews the evidence that early-life exposure to sex steroid hormones contributes to sexually dimorphic behavior and cognitive abilities in humans.

Abstract
Congenital adrenal hyperplasia could provide a promising model for the study of the effects of hormones on cognition. The aim of this study was to assess sexual dimorphic abilities related to oral language, spatial abilities, and verbal fluency and to determine the existence of learning disabilities in 11 congenital girls with adrenal hyperplasia compared with 11 healthy girls. Both groups underwent a neuropsychological evaluation using the Child Neuropsychological Assessment battery for Spanish-speaking children. Results showed that the congenital adrenal hyperplasia group had a significantly lower performance than the control group in the repetition and expression domains, right-left comprehension task, and verbal semantic fluency task. A higher incidence of learning disabilities (predominantly reading related) in the patient group compared with their controls was also evident. Thus, the presence of weak verbal areas along with a high incidence of learning disabilities related primarily, though not exclusively, to reading was documented in these girls.

Abstract
OBJETIVO: Avaliar o padrão de crescimento de pacientes com hiperplasia adrenal congênita com a forma clássica da deficiência da 21-hidroxilase (21-OH), em relação ao controle hormonal e ao uso de corticóide no tratamento. MÉTODOS: Análise retrospectiva dos prontuários de 45 pacientes. Como padrão de crescimento, foi utilizado o ganho ou não de altura, avaliando-se a diferença entre o escore Z da estatura na última consulta (para idade óssea) em relação ao escore Z da estatura no início do tratamento (para a idade cronológica). Foram avaliadas todas as concentrações de 17-OH progesterona (17-OHP), androstenediona e renina, sendo considerados bem controlados os pacientes com 50% ou mais das dosagens normais. Em relação ao corticóide, foram analisados o tipo e a dose. RESULTADOS: A idade na última consulta variou de 2,8 a 26,6 anos (12,6+5,8 anos), sendo 31 do sexo feminino, 30 com a forma perdedora de sal; 62% foram considerados bem controlados para 17-OHP, 75% para androstenediona e 78% para renina. A hidrocortisona foi usada por 41 pacientes (20,2+2,6 mg/m²/dia) e, por 40, em associação com a 9a-fludrocortisona. Encontrou-se 14 pacientes com ganho, 20 com manutenção e 11 com perda estatural. Os pacientes perdedores de sal (p=0,01) e os bem controlados (p=0,0005) para 17-OHP e androstenediona apresentaram associação significativa com o ganho de estatura. CONCLUSÕES: Nesta amostra de pacientes com a forma clássica da deficiência da 21-OHD, o melhor crescimento apresentou associação com o bom controle laboratorial da 17-OHP e da androstenediona e com a forma perdedora de sal.

Abstract
Testicular adrenal rests are encountered in ACTH hypersecretion syndromes, most often in congenital adrenal hyperplasia attributable to a deficit in 21-hydroxylase. They are discovered clinically or on systematic sonography, generally in the young adult. On sonography, they appear as confluent hypoechogenic masses, often bilateral, that have developed in the region of the testicular hilum. At a late stage, they take on a highly suggestive attenuating aspect. In color Doppler, they have a regular vascular architecture. They generally regress or stabilize with replacement glucocorticosteroid treatment. They can sometimes progress, which then poses the problem of the type of lesion. Biopsy or spermatic vein samples are not reliable. MRI contributes very little more than sonography. Diagnosis comes with follow-up or, as a last resort, orchidectomy.

Abstract
OBJETIVOS: Analisar a freqüência de indivíduos afetados e das formas clínicas da doença, de acordo com o gênero e a taxa de consangüinidade, em famílias com hiperplasia adrenal congênita (HAC) por deficiência da enzima 21-hidroxilase, forma clássica (HAC-D21-OHC). MÉTODOS: A casuística foi composta por 58 famílias com 79 indivíduos afetados (67 vivos e 12 mortos) com pais normais e pelo menos um filho afetado vivo com diagnóstico comprovado da doença. A freqüência de indivíduos afetados foi avaliada pelas técnicas de Haldane e Hogben, com análise por seleção truncada. Também foram avaliadas a história parental de consangüinidade e a freqüência de homozigose de mutações no gene CYP21A2, bem como a forma clínica da doença e a distribuição por gênero. RESULTADOS: Dez famílias apresentaram história de consangüinidade entre os pais e mais cinco com homozigose no estudo molecular. A freqüência de indivíduos afetados nas irmandades avaliadas foi de 23,5%, semelhante à esperada de 25%; no entanto, com distribuição heterogênea. Quanto às formas clínicas, 56 (70%) eram perdedores de sal (25M:31F) e 23 (30%) virilizantes simples (10M:13F), não sendo observada diferença na distribuição entre os gêneros. CONCLUSÕES: Estes dados confirmam que a HAC-D21-OHC apresenta padrão de herança monogênica autossômica recessiva, com freqüência de 23,5% na irmandade de indivíduos afetados, elevada taxa de consangüinidade e proporção semelhante entre os gêneros, porém com distribuição heterogênea no número de casos nas irmandades e predomínio da forma clínica perdedora de sal.

Abstract
Seven Chinese patients (5 males and 2 females) with vaccination-induced acute metabolic crisis were reported. Only one male with 21-hydroxylase deficiency had been diagnosed before vaccination. In the remaining six patients, the preexisting diagnoses were not confirmed before the vaccination. Acute metabolic crisis occurred in seven patients between 3 and 12 hours after the administration of Japanese encephalitis, diphtheria, and tetanus toxoids and acellular pertussis, hepatitis B, or measles vaccines. Patients 1 and 2 displayed acute adrenal insufficiencies at the ages of 5 years and 3 months, respectively. Patient 3 had presented with mild motor retardation previously. Patients 4 to 7 were previously healthy, but suffered from fever, seizures, coma, acidosis, and hypoglycemia after being vaccinated. Glutaric aciduria type 1 was evident in case 4. Leigh syndromes were present in Patients 5, 6, and 7. They all died from respiratory failure before 2 years of age. Symmetric foci, cystic cavitations with neuronal loss, and vascular proliferation were observed by postmortem examination. Among the seven patients, although the vaccines were not the primary cause of the acute metabolic crisis, the severe acute episodes occurred coincidentally.

Abstract
This article reviews the literature on studies and case reports on gender identity and gender identity problems, gender dysphoria, and gender change in chromosomal females with congenital adrenal hyperplasia, raised male or female. The large majority (94.8%) of the patients raised female (N= 250) later developed a gender identity as girls and women and did not feel gender dysphoric. But 13 (5.2%) patients had serious problems with their gender identity. This percentage is higher than the prevalence of female-to-male transsexuals in the general population of chromosomal females. Among patients raised male, serious gender identity problems were reported in 4 (12.1%) out of 33 patients. From these observations, we conclude that the assignment to the female gender as a general policy for 46,XX patients with CAH appears justified, even in severely masculinized 46,XX newborns with CAH (Prader stage IV or V).

Abstract
AIMS To evaluate the incidence of congenital adrenal hyperplasia (CAH) in the Northern Italian population and the efficiency of the North-Eastern Italy screening program. To adjust cut-off levels for 17-hydroxyprogesterone (17-OHP) in relation to gestational age and birth weight, comparing the benefits in terms of reduction of recall rates with the two approaches and ultimately choosing the better of the two. SUBJECTS AND METHODS Since September 2001, blood samples from neonates born in North-Eastern Italy have been screened with a fluoroimmunoassay method for 17-OHP determination (DELFIA). A preliminary cut-off level of > or = 30 nmol/l was set both for term and preterm newborns. The values of 17-OHP were analysed using statistical methods in relation to gestational age and birth weight in order to modify the cut-off on the basis of our data. RESULTS After 33 months of screening we screened 128,282 newborns and detected 6 affected babies. During the first 8 months of screening among the recalled babies, 89.6 and 78.1% were preterm and low-birth-weight newborns, respectively, with a recall rate of 2.59% for premature neonates and of 4.94% for babies with birth weights < 2,500 g. We chose a new cut-off value of 50 nmol/l for preterm newborns only and, after 4 months, the recall rate was reduced to 0.83% for these infants and to 1.83% for low-birth-weight infants. CONCLUSION After 33 months of screening for CAH in North-Eastern Italy, we report an incidence of 1:21,380. In 5 out of 6 affected babies, the diagnosis was established only after a positive screening test, which prevented a severe salt-wasting crisis in these babies. The cut-off level related to gestational age led to a significant reduction in the number of false-positives among preterm babies.We therefore intend to continue with the screening program for CAH in North-Eastern Italy, keeping a gestational-age-related cut-off in the hope that our data may encourage a national screening program for CAH.

Abstract
A calico-colored domestic shorthair cat was examined because of possible cryptorchidism. The cat had a fully formed penis, prepuce, and scrotum, but no descended testes, and exploratory laparotomy revealed a grossly normal female internal genital tract (ie, 2 ovaries, 2 uterine horns, and uterine body). Chromosomal analysis revealed a normal female (38,XX) karyotype. Four months later, the cat was examined because of polyuria, polydipsia, and inappropriate urination. Serum cortisol and aldosterone concentrations were low, and results of an ACTH stimulation test were suggestive of decreased adrenal gland function. Serum ACTH, testosterone, androstenedione, progesterone, 17-hydroxyprogesterone, 11-deoxycortisol, and deoxycorticosterone concentrations were high, and a diagnosis of congenital adrenal hyperplasia secondary to 11beta-hydroxylase deficiency was made. Treatment with prednisone diminished clinical signs but had a variable effect on corticosteroids hormone concentrations. To the author's knowledge, this is the first report of congenital adrenal hyperplasia in a cat.

Abstract
This study evaluated the degree of femininity and masculinity at different developmental stages in a group of adult women, some of whom were exposed to elevated prenatal adrenal androgens as a result of congenital adrenal hyperplasia (CAH) due to 21 hydroxylase (21-OH) deficiency. Women who had presented to the Johns Hopkins Hospital Pediatric Endocrine Clinic for treatment of CAH due to 21-OH deficiency were included. The control group consisted of sisters of CAH participants and women referred for evaluation of polycystic ovary syndrome. Study participants were given a questionnaire asking them to indicate their degree of masculinity and femininity during childhood, adolescence, and adulthood. In addition, participants were asked questions related to their play behavior during childhood, including playmate preferences, toy preferences, and admiration of male or female characters during fantasy play. Across participant groups, self-reported femininity decreased in a dose response manner, according to prenatal androgen exposure. For all groups, femininity increased through developmental stages. Women with salt-losing CAH remained less feminine than controls into adulthood. Conversely, self-reported masculinity increased in a dose-response manner, according to prenatal androgen exposure, across participant groups. Women with CAH showed a decrease in masculinity across developmental stages, such that by adulthood, there were no significant differences in masculinity between controls and the women with CAH. Women with salt-losing CAH were more likely to recall preferences for boy playmates, male-typical toys, and admiration for male characters during childhood than other study participants. Our data support the effect of both prenatal androgen exposure and socialization on gender role behavior in adult women with CAH due to 21-OH deficiency.

Abstract
OBJECTIVE To review one physician's management of glucocorticoid replacement therapy in adult patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency and to determine the efficacy and the range of effective doses of dexamethasone in managing the clinical and biochemical consequences of this disorder. METHODS We conducted a retrospective clinical practice audit of nine patients treated by a single physician for 21-hydroxylase deficiency during the period from March 1998 to January 2002. We documented biochemical control and clinical features of glucocorticoid excess or deficiency for various doses of dexamethasone. RESULTS The final dosage of dexamethasone needed to normalize serum 17-hydroxyprogesterone levels, to arrest progression of hirsutism, and to eliminate the symptoms and signs of adrenocortical insufficiency while avoiding manifestations of glucocorticoid excess ranged from 0.0625 to 0.875 mg/day, with a mean dosage of 0.4 mg/day. Seven patients had adequate control during the observation period with use of dosages of dexamethasone of 0.5 mg/day or less. CONCLUSION Adequate control of 21-hydroxylase can be achieved with relatively low doses of dexamethasone; thus, the long-held notion that 0.75 mg of dexamethasone is "equivalent" in glucocorticoid effect to the estimated daily production of cortisol is challenged. These data suggest that physicians should evaluate the doses of glucocorticoids used in their patients with CAH and other forms of primary and central adrenocortical insufficiency because considerable decreases in glucocorticoid doses may be in order.

Abstract
Prednisolone has unknown growth-suppressing effects relative to other steroids. We retrospectively studied 9 children (6 with congenital adrenal hyperplasia, CAH) receiving hydrocortisone replacement after switching to prednisolone (dose ratio, 1:5). Growth velocity and, in patients with CAH, 17-OHP decreased significantly. Dose reduction reversed these effects. Roughly, growth suppression relative potency for prednisolone:hydrocortisone was 15:1.

Abstract
21-hydroxylase deficiency (P450 CYP21) accounts for 90% of cases of congenital adrenal hyperplasia (CAH), which is associated with abnormally low cortisol and high production of androgen precursors and is the most common cause of ambiguous genitalia. Increased androgen causes in utero virilization of the fetus, consisting of clitoral enlargement, an urogenital sinus, and labioscrotal enlargement and fusion. This is the first case in an experience covering more than 30 years, of a 46,XX patient raised as a boy. The authors report a case of a Pakistani patient born of a consanguineous union, who came to medical attention at age 3 because of severe genital ambiguity; genetic analyses showed that the child was a compound heterozygote for CAH. The surgical management of this patient consisted of (1) staged hypospadias repairs preceded by testosterone therapy, (2) creation of a bladder graft neourethra, (3) removal of müllerian structures, (4) correction of bifid prepenile scrotum, and (5) insertion of testicular prostheses. The commitment to raise a 46,XX child as a boy is a very rare event. With a series of staged complex surgical procedures and careful steroid replacement, normal secondary sexual characteristics can be achieved in these children.

Abstract
The purpose of this study was to investigate the prevalence of testicular adrenal rest tumours in patients with congenital adrenal hyperplasia (CAH), and to describe sonographic and MR features of these lesions. Seventeen postpubertal male CAH patients underwent scrotal sonography, with colour Doppler, and in 16 of them pre- and postcontrast enhanced T1- and T2-weighted MR images of the testes were obtained. Ultrasound revealed lesions in 16 of 17 patients (94%), bilateral in 10 patients and unilateral in 6 patients. The lesions were typically located adjacent to the mediastinum testis. The maximal diameter of the lesions varied from 2 to 40 mm. Margins were blurred in 11 of 31 lesions. Seventeen of the 20 lesions smaller than 2 cm in diameter were hypoechoic, whereas all 11 lesions larger than 2 cm showed hyperechoic reflections. On MR all lesions were isointense on T1- and hypointense on T2-weighted images and lesion margins were clearly defined. Enhancement of the lesions after intravenous contrast was seen in 13 of 15 patients. In our series the prevalence of testicular adrenal rest tumours in postpubertal CAH patients is much higher than in other reported studies. The lesions may develop from some small, hypoechoic, and multifocal nodules and coalesce to large hypoechoic lesions with hyperechoic reflections on ultrasound. As our results suggest that ultrasonography and MR show the lesions equally well, ultrasonography should be the method of first choice for detection and follow-up of these lesions, because it is the cheapest and quickest imaging technique. In case of a partial orchiectomy, MR is recommended because it shows lesion margins optimally.

Abstract
To address questions about sex assignment in children with ambiguous genitalia, we studied gender identity in girls with congenital adrenal hyperplasia (CAH) in relation to characteristics of the disease and treatment, particularly genital appearance and surgery. A 9-item gender identity interview was administered to 43 girls with classical CAH ranging in age from 3-18 yr, 7 tomboys, and 29 sister control girls. Groups were compared on total score and on individual items. Results showed that, on the total gender identity score, 88% of girls with CAH had scores overlapping those of control girls, but the average score was intermediate between control girls and tomboys. On individual items of gender identity (discomfort as a girl, wish to be a boy), girls with CAH were similar to control girls. Gender identity in girls with CAH was not related to degree of genital virilization or age at which genital reconstructive surgery was done. Thus, moderate androgen excess early in development appears to produce a small increase in the risk of atypical gender identity, but this risk cannot be predicted from genital virilization.

Abstract
OBJECTIVE We investigated adrenal steroidogenic function relevant to 3beta-hydroxysteroid dehydrogenase (HSD3B2) activity in vivo and HSD3B2 genotype in clinically normal family members of patients with HSD3B2 genotype-proven HSD3B2 deficiency congenital adrenal hyperplasia (CAH) to determine whether genotype-proven carriers for HSD3B2 deficiency exhibit decreased enzyme activity analogous to the mildly decreased adrenal 21-hydroxylase activity in the carriers of CYP21 gene mutation. DESIGN/PATIENTS Nineteen adult family members (ages median/range: 37/19-56 years) including 13 females and six males of six unrelated patients with HSD3B2 genotype-proven HSD3B2 deficiency were studied. MEASUREMENTS All family members had HSD3B2 DNA analysis and an ACTH stimulation test (Cortrosyn 0.25 mg IV bolus) for determination of adrenal HSD3B activity. RESULTS Ten of 13 females and five of six males were carriers of a proven or predictably deleterious mutation in one allele of the HSD3B2 gene, which was identified in the probands. ACTH-stimulated levels of 17-hydroxypregnenolone (delta5-17P), 17-hydroxyprogesterone (17-OHP), cortisol (F), dehydroepiandrosterone (DHEA) and androstenedione (delta4-A) and ratios of delta5-17P to 17-OHP, delta5-17P to F and DHEA to delta4-A, as well as increments of delta5-17P and DHEA values (ACTH-stimulated - baseline) in the genotype-proven female carriers (age, mean +/- SD: 36 +/- 6.7 years) and male carriers (age, mean +/- SD: 37 +/- 6.7 years) did not differ significantly from age-matched normal females (35 +/- 5.4 years, n = 20) and normal males (35 +/- 6 years, n = 10), respectively. There were no significant differences in any of the ACTH-stimulated hormonal levels or ratios between the female carriers with a seriously deleterious genotype (n = 5) and the female carriers with mildly deleterious genotypes (n = 5). These hormonal levels and ratios in three genotype-normal females and one genotype-normal male overlapped with those of the carriers. CONCLUSION These data suggest that normal adrenal HSD3B2 activity is maintained in the genotype-proven carriers because heterodimers of mutant and wild-type HSD3B2 enzymes may be stable and exhibit similar activity compared to homodimers of wild-type enzymes, possibly by a relatively rate-unlimited effect of haplo-wild-type enzyme activity. However, we cannot preclude entirely the possibility of a limited expression of another HSD3B activity under ACTH stimulation contributing to the normal adrenal HSD3B activity in vivo in the HSD3B2 genotype-proven heterozygotes. Which mechanism plays a role in maintaining normal enzyme activity in the heterozygotes remains to be elucidated. The hormone findings in the genotypic-proven carriers for HSD3B2 deficiency also indicate that carriers for this disorder cannot be detected by a hormone test and can only be detected by HSD3B2 genotype study.

Abstract
We report a 3-month-old boy who suffered an out-of-hospital cardiac arrest. During resuscitation, the medical team was informed that he was receiving hydrocortisone treatment. The possibility of adrenal insufficiency with hyperkalemic cardiac arrest prompted the administration of calcium, which resulted in the return of spontaneous circulation. The infant's diagnosis of congenital adrenal hyperplasia was not spontaneously mentioned by the parents. This case illustrates the importance of obtaining adequate parental information and considering hyperkalemia as a possible cause of cardiac arrest.

Abstract
Three different new mutations were found after CYP21 gene sequencing in three unrelated patients with the classical form of the 21-hydroxylase deficiency. These mutations were also screened in their affected relatives. In one patient and her brother, both affected with the simple virilizing form and in their aunt, with the nonclassical form, an AG>GG transition was found in the acceptor site of intron 2. In another patient with the salt wasting form, we found a 1003 1004 insA, in exon 4, that altered the reading frame and created a stop codon in codon 297. In the third patient and his sister, we found a C>T transition in codon 408. This transition led to the substitution of arginine by cysteine (R408C) in a conserved region where arginine is conserved in at least four different species. These siblings with the R408C mutation, both affected with the salt wasting form, have the IVS2-13A/C>G mutation in the other allele, suggesting that the R408C should lead to complete impairment of enzymatic activity. To rule out the possibility of polymorphism, R408C was screened through allele specific PCR, and it was not found in 100 normal alleles. The screening of these three new mutations by allele-specific PCR or enzymatic restriction in 212 CAH patients disclosed their presence in 2.3% (9/387) of the alleles. All three new mutations were found in compound heterozygous state with previously known mutations. Microsatellite studies, using markers flanking CYP21 gene, revealed that each new mutation presents the same haplotype, suggesting a gene founder effect, similar to what was previously observed with the G424S mutation also described in our population. Although microconversion events are the main cause of mutations in the CYP21 gene, random mutations with a common origin can also be the cause of 21-hydroxylase deficiency.

Abstract
Abstract
Background: Congenital adrenal hyperplasia (CAH) is a frequent autosomal recessive disease, with a wide range of clinical manifestations, most commonly attributable to mutations in the 21-hydroxylase gene (CYP21). Large gene deletions, large gene conversions, a small 8-basepair deletion, and eight point mutations in CYP21 account for ∼95% of all enzyme deficiencies. We developed a new strategy for a rapid CYP21 analysis.
Methods: DNA samples from 40 CAH patients previously genotyped by direct DNA sequencing were reanalyzed by allele-specific amplification of the functional CYP21 gene followed by a multiplex minisequencing reaction using 13 primers. In addition, a second PCR that amplified a part of exon 3 was used to demonstrate the presence or absence of at least one functional gene.
Results: The assay detected the P453S mutation and nine of the most common mutations (P30L, intron 2 splice, Δ8bp, I172N, exon 6 cluster, V281L, F306+t, Q318X, and R356W) caused by microconversions from the CYP21P pseudogene. The concordance was 100% for detecting these mutations, including gene deletions and large gene conversions. The 40 patient DNA samples were analyzed in 1.5 working days by one technician (actual hands-on time, 3.5 h). The material cost for analyzing one sample was approximately €10.00 (US $9.00).
Conclusions: This novel mutation screening strategy rapidly detects 90–95% of all mutations associated with CAH and appears applicable as a tool for confirmation of increased 17-hydroxyprogesterone found in neonatal CAH screening.

Abstract
Cognition in patients with CAH has not been as well studied as other aspects of psychologic function. Nevertheless, it is possible to make some conclusions and to offer a number of hypotheses for further study (Table 1). First, patients with CAH do not seem to have an overall intellectual advantage as a direct consequence of the disease. The high IQs reported in some groups of patients with CAH are also reported in their siblings and probably reflect sampling bias. Second, it is possible that, on average, patients with salt-wasting CAH have lower overall ability than patients with the simple-virilizing form, but both groups are well within the normal range, and there is considerable variability among both groups. Third, the evidence to date does not confirm that patients with CAH are more likely to have diagnosable learning disabilities when compared with their unaffected relatives, but this issue has not been well studied with the appropriate psychoeducational assessments. It is unlikely that patients with CAH are at substantially increased risk for frank learning disabilities, but they may be likely to have problems in specific areas. Fourth, females with CAH seem to have enhanced spatial ability as a result of exposure to high levels of androgens early in development. The neural substrate of this advantage is unknown but a subject of active research. It is unclear whether when compared with their unaffected siblings, females with CAH are better in other abilities that are typically performed best by males or worse in abilities typically performed best by females. Fifth, it is likely that patients with CAH have other cognitive changes as a consequence of disease characteristics (besides androgens) and of the treatment of the disease. Some evidence suggests that patients with CAH are more likely to have white-matter brain changes produced by the disease and its treatment. This has not been well studied but should be because of the potential clinical implications. It is reasonable to hypothesize that there will be cognitive changes that reflect effects of undertreatment (e.g., ACTH effects on attention) and other changes that reflect effects of overtreatment (e.g., glucocorticoid effects on memory). Some of these effects may be transient, reflecting acute brain changes, whereas others may become chronic as a result of permanent brain changes with repeated exposure. There is need for continuing study of cognition in patients with CAH. Such studies will provide basic information about hormonal effects on cognition and the neural mechanisms that mediate those effects. They will also provide important clinical information to guide psychologic and medical treatment of patients.
