Abstract
Congenital adrenal hyperplasia is a group of autosomal recessive disorders encompassing enzyme deficiencies in the adrenal steroidogenesis pathway that lead to impaired cortisol biosynthesis. Depending on the type and severity of steroid block, patients can have various alterations in glucocorticoid, mineralocorticoid, and sex steroid production that require hormone replacement therapy. Presentations vary from neonatal salt wasting and atypical genitalia, to adult presentation of hirsutism and irregular menses. Screening of neonates with elevated 17-hydroxyprogesterone concentrations for classic (severe) 21-hydroxylase deficiency, the most common type of congenital adrenal hyperplasia, is in place in many countries, however cosyntropin stimulation testing might be needed to confirm the diagnosis or establish non-classic (milder) subtypes. Challenges in the treatment of congenital adrenal hyperplasia include avoidance of glucocorticoid overtreatment and control of sex hormone imbalances. Long-term complications include abnormal growth and development, adverse effects on bone and the cardiovascular system, and infertility. Novel treatments aim to reduce glucocorticoid exposure, improve excess hormone control, and mimic physiological hormone patterns.

Abstract
Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders of adrenal steroidogenesis. Disorders in steroid 21-hydroxylation account for over 95% of patients with CAH. Clinically, the 21-hydroxylase deficiency has been classified in a broad spectrum of clinical forms, ranging from severe or classical, to mild late onset or non-classical. Known allelic variants in the disease causing CYP21A2 gene are spread among different sources. Until recently, most variants reported have been identified in the clinical setting, which presumably bias described variants to pathogenic ones, as those found in the CYPAlleles database. Nevertheless, a large number of variants are being described in massive genome projects, many of which are found in dbSNP, but lack functional implications and/or their phenotypic effect. In this work, we gathered a total of 1,340 GVs in the CYP21A2 gene, from which 899 variants were unique and 230 have an effect on human health, and compiled all this information in an integrated database. We also connected CYP21A2 sequence information to phenotypic effects for all available mutations, including double mutants in cis. Data compiled in the present work could help physicians in the genetic counseling of families affected with 21-hydroxylase deficiency.

Abstract
Scrotal hair is a clinical condition that occurs rarely in infancy. Its prevalence is not known. We present a retrospective analysis of six patients referred to our pediatric endocrinology clinic. Except for scrotal hair development, all physical examinations were normal. Underlying pathologic hyperandrogenism was excluded in each case. Clinical regression was observed in all four infants with documented follow-up visits. Scrotal hair in infancy is not well known to most pediatricians and dermatologists and can cause parental anxiety. Our cases are typical of the benign course of isolated scrotal hair.

Abstract
The steroid hormone 17α-hydroxylprogesterone (17-OHP) is a biomarker for congenital adrenal hyperplasia and hence there is considerable interest in development of sensors for this compound. We used computational protein design to generate protein models with binding sites for 17-OHP containing an extended, nonpolar, shape-complementary binding pocket for the four-ring core of the compound, and hydrogen bonding residues at the base of the pocket to interact with carbonyl and hydroxyl groups at the more polar end of the ligand. Eight of 16 designed proteins experimentally tested bind 17-OHP with micromolar affinity. A co-crystal structure of one of the designs revealed that 17-OHP is rotated 180° around a pseudo-two-fold axis in the compound and displays multiple binding modes within the pocket, while still interacting with all of the designed residues in the engineered site. Subsequent rounds of mutagenesis and binding selection improved the ligand affinity to nanomolar range, while appearing to constrain the ligand to a single bound conformation that maintains the same "flipped" orientation relative to the original design. We trace the discrepancy in the design calculations to two sources: first, a failure to model subtle backbone changes which alter the distribution of sidechain rotameric states and second, an underestimation of the energetic cost of desolvating the carbonyl and hydroxyl groups of the ligand. The difference between design model and crystal structure thus arises from both sampling limitations and energy function inaccuracies that are exacerbated by the near two-fold symmetry of the molecule.

Abstract
The study explored differences in the steroidogenic pathway between obese and nonobese women with polycystic ovary syndrome (PCOS) using liquid chromatography-tandem mass spectrometry (LC-MS/MS). 1044 women with PCOS (including 350 lean, 312 overweight and 382 obese) and 366 control women without PCOS (including 203 lean, 32 overweight and 131 obese) were enrolled. The differences in steroid hormones were amplified in lean PCOS versus lean controls compared with obese PCOS versus obese controls. Compared with obese PCOS, lean PCOS demonstrated increased dehydroepiandrosterone sulfate (P = 0.015), 17-hydropregnenolone (P = 0.003), 17-hydroprogesterone (17-OHP) (P < 0.001), progesterone (P < 0.001) and estrone (P < 0.001) levels. Enzyme activity evaluation showed that lean PCOS had increased activity of P450c17 (17-hydropregnenolone/pregnenolone, P < 0.001), P450aro (P < 0.001), 3βHSD2 (progesterone/ pregnenolone and 17-OHP/17-hydropregnenolone, both P < 0.001) and decreased activity of P450c21(11-deoxycorticorsterone/progesterone and 11-deoxycortisol/17-OHP, P < 0.001). Moreover, we found higher frequencies of CYP21A2- (encoding P450c21) c.552 C > G (p. D184E) in lean PCOS compared with obese PCOS patients (P = 0.006). In conclusion, this study demonstrated for the first time that the adrenal-specific enzyme P450c21 showed decreased activity in lean PCOS patients, and that the adrenal androgen excess may play different roles in lean and obese PCOS patients, which represents as different enzyme activity in the steroidogenic pathway.

Abstract
BACKGROUND The aim of this study was to describe the gray-scale and color Doppler ultrasonography (US) and magnetic resonance (MR) imaging features of testicular adrenal rest tumors (TART) in patients with congenital adrenal hyperplasia. MATERIAL/METHODS Forty-one patients with congenital adrenal hyperplasia were evaluated by gray-scale and color Doppler ultrasonography. Totally eighteen adrenal rest tumors in 9 patients were diagnosed TART on US and MR imaging. Gray-scale and color Doppler US and MR findings of the patients were documented. RESULTS A total of eighteen masses were evaluated in nine patients. The mean age of these patients was 14.3±4.5 (range 10.1-23.3) years. US revealed hypoechoic lesions around the mediastinum testis with hypervascularity dispersing in ten patients and hypovascularity in two patients. In six patients, the lesions were hyperechoic with poor vascularity. Lesions exhibited homogeneous (n=8) and heterogeneous (n=10). Testicular microlithiasis was present in 4 of 9 patients with TART. Doppler ultrasound showed normal testicular vessels passing through the mass which were undisturbed, not displaced and not change in caliber. MRI features were the following: all lesions were hypointense on T2- and hyperintense (n=12) and isointense (n=6) on T1-weighted images. All masses revealed homogeneous contrast enhancement on postcontrast T1-weighted images. CONCLUSIONS Ultrasonography and MRI are good methods for detecting and monitoring TART. US is the first preferable modality because it is quick and cheap than MRI. Bilateral mostly hypoechoic lesions depicted around the mediastinum testis with no mass effect is highly suggestive for the diagnosis of testicular adrenal rest tissues on ultrasonography. Normal testicular vessels coursing through the lesions undisturbed and not change in caliber is described specific for this kind of tumors.

Abstract
During pregnancy, cell-free DNA (cfDNA) in maternal blood encompasses a small percentage of cell-free fetal DNA (cffDNA), an easily accessible source for determination of fetal disease status in risk families through non-invasive procedures. In case of monogenic heritable disease, background maternal cfDNA prohibits direct observation of the maternally inherited allele. Non-invasive prenatal diagnostics (NIPD) of monogenic diseases therefore relies on parental haplotyping and statistical assessment of inherited alleles from cffDNA, techniques currently unavailable for routine clinical practice. Here, we present monogenic NIPD (MG-NIPD), which requires a blood sample from both parents, for targeted locus amplification (TLA)-based phasing of heterozygous variants selectively at a gene of interest. Capture probes-based targeted sequencing of cfDNA from the pregnant mother and a tailored statistical analysis enables predicting fetal gene inheritance. MG-NIPD was validated for 18 pregnancies, focusing on CFTR, CYP21A2, and HBB. In all cases we could predict the inherited alleles with >98% confidence, even at relatively early stages (8 weeks) of pregnancy. This prediction and the accuracy of parental haplotyping was confirmed by sequencing of fetal material obtained by parallel invasive procedures. MG-NIPD is a robust method that requires standard instrumentation and can be implemented in any clinic to provide families carrying a severe monogenic disease with a prenatal diagnostic test based on a simple blood draw.

Abstract
The advent of mass spectrometry into the clinical laboratory has led to an improvement in clinical management of several endocrine diseases. Liquid chromatography tandem mass spectrometry found some of its first clinical applications in the diagnosis of inborn errors of metabolism, in quantitative steroid analysis, and in drug analysis laboratories. Mass spectrometry assays offer analytical sensitivity and specificity that is superior to immunoassays for many analytes. This article highlights several areas of clinical endocrinology that have witnessed the use of liquid chromatography tandem mass spectrometry to improve clinical outcomes.

Abstract
Female androgen excess and male androgen deficiency manifest with an overlapping adverse metabolic phenotype, including abdominal obesity, insulin resistance, type 2 diabetes mellitus, non-alcoholic fatty liver disease and an increased risk of cardiovascular disease. Here, we review the impact of androgens on metabolic target tissues in an attempt to unravel the complex mechanistic links with metabolic dysfunction; we also evaluate clinical studies examining the associations between metabolic disease and disorders of androgen metabolism in men and women. We conceptualise that an equilibrium between androgen effects on adipose tissue and skeletal muscle underpins the metabolic phenotype observed in female androgen excess and male androgen deficiency. Androgens induce adipose tissue dysfunction, with effects on lipid metabolism, insulin resistance and fat mass expansion, while anabolic effects on skeletal muscle may confer metabolic benefits. We hypothesise that serum androgen concentrations observed in female androgen excess and male hypogonadism are metabolically disadvantageous, promoting adipose and liver lipid accumulation, central fat mass expansion and insulin resistance.

Abstract
These pediatric hypertension guidelines are an update to the 2004 "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents." Significant changes in these guidelines include (1) the replacement of the term "prehypertension" with the term "elevated blood pressure," (2) new normative pediatric blood pressure (BP) tables based on normal-weight children, (3) a simplified screening table for identifying BPs needing further evaluation, (4) a simplified BP classification in adolescents ≥13 years of age that aligns with the forthcoming American Heart Association and American College of Cardiology adult BP guidelines, (5) a more limited recommendation to perform screening BP measurements only at preventive care visits, (6) streamlined recommendations on the initial evaluation and management of abnormal BPs, (7) an expanded role for ambulatory BP monitoring in the diagnosis and management of pediatric hypertension, and (8) revised recommendations on when to perform echocardiography in the evaluation of newly diagnosed hypertensive pediatric patients (generally only before medication initiation), along with a revised definition of left ventricular hypertrophy. These guidelines include 30 Key Action Statements and 27 additional recommendations derived from a comprehensive review of almost 15 000 published articles between January 2004 and July 2016. Each Key Action Statement includes level of evidence, benefit-harm relationship, and strength of recommendation. This clinical practice guideline, endorsed by the American Heart Association, is intended to foster a patient- and family-centered approach to care, reduce unnecessary and costly medical interventions, improve patient diagnoses and outcomes, support implementation, and provide direction for future research.

Gu C, Tan H, Yang J, Lu Y, Ma Y. Congenital adrenal hyperplasia due to 11-hydroxylase deficiency-Compound heterozygous mutations of a prevalent and two novel CYP11B1 mutations. Gene 2017; 626:89-94. [PMID: 28514642 DOI: 10.1016/j.gene.2017.05.029] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2017] [Revised: 03/31/2017] [Accepted: 05/11/2017] [Indexed: 02/05/2023]
Abstract
11β-hydroxylase deficiency (11β-OHD) occurs in about 5-8% of congenital adrenal hyperplasia (CAH). In this study, we identified three CYP11B1 (encoding Cytochrome P450 11B1) heterozygous mutations: c.1358G>C (p.R453Q), c.1229T>G (p.L410R) and c.1231G>T (p.G411C) in a Chinese CAH patient due to classic 11β-OHD. His parents were healthy and respectively carried the prevalent mutation c.1358G>C (p.R453Q), and the two novel mutations c.1229T>G (p.L410R) and c.1231G>T (p.G411C). In vitro expression studies, immunofluorescence demonstrated that wild type and mutant (L410R and G411C) proteins of CYP11B1 were correctly expressed on the mitochondria, and enzyme activity assay revealed the mutant reduced the 11-hydroxylase activity to 10% (P<0.001) for the conversion of 11β-deoxycortisol to cortisol. Subsequently, three dimensional homology models for the normal and mutant proteins were built by using the x-ray structure of the human CYP11B2 as a template. Interestingly, in the heme binding site I helix, a change from helix to loop in four amino acide took place in the mutant model. In conclusion, this study expands the spectrum of mutations in CYP11B1 causing to 11β-OHD and provides evidence for prenatal diagnosis and genetic counseling. In addition, our results confirm the two novel CYP11B1 mutations led to impaired 11-hydroxylase activity in vitro.

The steroid metabolome in women with premenstrual dysphoric disorder during GnRH agonist-induced ovarian suppression: effects of estradiol and progesterone addback. Transl Psychiatry 2017; 7:e1193. [PMID: 28786978 PMCID: PMC5611719 DOI: 10.1038/tp.2017.146] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2016] [Revised: 05/05/2017] [Accepted: 05/26/2017] [Indexed: 01/08/2023] Open
Abstract
Clinical evidence suggests that symptoms in premenstrual dysphoric disorder (PMDD) reflect abnormal responsivity to ovarian steroids. This differential steroid sensitivity could be underpinned by abnormal processing of the steroid signal. We used a pharmacometabolomics approach in women with prospectively confirmed PMDD (n=15) and controls without menstrual cycle-related affective symptoms (n=15). All were medication-free with normal menstrual cycle lengths. Notably, women with PMDD were required to show hormone sensitivity in an ovarian suppression protocol. Ovarian suppression was induced for 6 months with gonadotropin-releasing hormone (GnRH)-agonist (Lupron); after 3 months all were randomized to 4 weeks of estradiol (E2) or progesterone (P4). After a 2-week washout, a crossover was performed. Liquid chromatography/tandem mass spectrometry measured 49 steroid metabolites in serum. Values were excluded if >40% were below the limit of detectability (n=21). Analyses were performed with Wilcoxon rank-sum tests using false-discovery rate (q<0.2) for multiple comparisons. PMDD and controls had similar basal levels of metabolites during Lupron and P4-derived neurosteroids during Lupron or E2/P4 conditions. Both groups had significant increases in several steroid metabolites compared with the Lupron alone condition after treatment with E2 (that is, estrone-SO4 (q=0.039 and q=0.002, respectively) and estradiol-3-SO4 (q=0.166 and q=0.001, respectively)) and after treatment with P4 (that is, allopregnanolone (q=0.001 for both PMDD and controls), pregnanediol (q=0.077 and q=0.030, respectively) and cortexone (q=0.118 and q=0.157, respectively). Only sulfated steroid metabolites showed significant diagnosis-related differences. During Lupron plus E2 treatment, women with PMDD had a significantly attenuated increase in E2-3-sulfate (q=0.035) compared with control women, and during Lupron plus P4 treatment a decrease in DHEA-sulfate (q=0.07) compared with an increase in controls. Significant effects of E2 addback compared with Lupron were observed in women with PMDD who had significant decreases in DHEA-sulfate (q=0.065) and pregnenolone sulfate (q=0.076), whereas controls had nonsignificant increases (however, these differences did not meet statistical significance for a between diagnosis effect). Alterations of sulfotransferase activity could contribute to the differential steroid sensitivity in PMDD. Importantly, no differences in the formation of P4-derived neurosteroids were observed in this otherwise highly selected sample of women studied under controlled hormone exposures.

Abstract
CONTEXT Patients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes. OBJECTIVE To identify biomarkers of disease control and long-term complications in 21OHD. SETTING AND PARTICIPANTS Cross-sectional study of 114 patients (70 males), ages 2 to 67 years (median, 15 years), seen in a tertiary referral center. METHODS We correlated a mass-spectrometry panel of 23 steroids, obtained before first morning medication, with bone age advancement (children), adrenal volume (adults), testicular adrenal rest tumors (TART), hirsutism, menstrual disorders, and pituitary hormones. RESULTS Total adrenal volume correlated positively with 18 steroids, most prominently 21-deoxycortisol and four 11-oxygenated-C19 (11oxC19) steroids: 11β-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11ketoA4), 11β-hydroxytestosterone (11OHT), and 11-ketotestosterone (11ketoT) (r ≈ 0.7, P < 0.0001). Nine steroids were significantly higher (P ≤ 0.01) in males with TART compared with those without TART, including 11OHA4 (6.8-fold), 11OHT (4.9-fold), 11ketoT (3.6-fold), 11ketoA4 (3.3-fold), and pregnenolone sulfate (PregS; 4.8-fold). PregS (28.5-fold) and 17-hydroxypregnenolone sulfate (19-fold) levels were higher (P < 0.01) in postpubertal females with menstrual disorders. In males, testosterone levels correlated positively with all 11oxC19 steroids in Tanner stages 1 and 2 (r ≈ 0.7; P < 0.001) but negatively in Tanner stage 5 (r = -0.3 and P < 0.05 for 11ketoA4 and 11ketoT). In females, testosterone level correlated positively with all four 11oxC19 steroids across all Tanner stages (r ≈ 0.8; P < 0.0001). CONCLUSION 11oxC19 steroids and PregS might serve as clinically useful biomarkers of disease control and long-term complications in 21OHD.

Abstract
PURPOSE OF REVIEW Acne vulgaris is a global disease with increasing prevalence in adolescents. It has a profound impact on their quality of life, especially when endocrine disorders are also involved. Recent concerns regarding antibiotic stewardship, failures with antibiotic usage, and the development of antibiotic-resistant Propionibacterium acnes have led clinicians to consider other therapeutic options for acne treatment. The present review explores hormonal therapies for the treatment of acne vulgaris. RECENT FINDINGS There are now four different combined oral contraceptive pills that are FDA approved for the treatment of acne since its first introduction in 1960. Recent literature has provided more information on the efficacy of different generations of combined oral contraceptive pills, their side-effects, and cancer risks. Furthermore, spironolactone has been gaining wider use among dermatologists in adolescents with endocrine dysfunction. New diagnostic guidelines and treatment recommendations have also been suggested. SUMMARY Hormonal therapies are effective and well tolerated options for the treatment of acne vulgaris in adolescents with and without endocrine disorders. They can be used as monotherapy or in conjunction with benzoyl peroxide, topical retinoic acid, or antibiotics.

Abstract
Congenital adrenal hyperplasia (CAH) refers to a group of autosomal recessive disorders due to single-gene defects in the various enzymes required for cortisol biosynthesis. CAH represents a continuous phenotypic spectrum with more than 95% of all cases caused by 21-hydroxylase deficiency. Genotyping is an important tool in confirming the diagnosis or carrier state, provides prognostic information on disease severity, and is essential for genetic counseling. In this article, the authors provide an in-depth discussion on the genetics of CAH, including genetic diagnosis, molecular analysis, genotype-phenotype relationships, and counseling of patients and their families.

Abstract
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder mainly caused by defects in the steroid 21-hydroxylase gene (CYP21A2). Most of CYP21A2 mutations result from intergenic recombinations between CYP21A2 and closely linked CYP21A1P pseudogene. Rare mutations not generated by gene conversion account for 5-10% of 21-hydroxylase deficiency alleles. Intronic variants represent only a little part of these but their effect on the protein is generally deleterious. The aim of this paper is to provide a comprehensive literary review regarding all intronic CYP21A2 pathological variants reported to date. In addition, we describe three novel causing disease variants in our patients affected by the classic form of CAH: IVS4-1G>A, IVS5-8T>A, IVS8-2A>G. In silico analysis revealed that all these substitutions affect the splicing process leading to a non-functional protein. Based on these results, we are able to classify them as pathological variants according to the patient's phenotype.

Abstract
Bone age (BA) advancement in prepubertal children may be associated with earlier onset of puberty and obesity. This study aimed to define the effects of adrenal androgen levels on the advancement of BA in prepubertal children, independent of obesity. During July and August 2011, we examined BA in 200 prepubertal children aged 7-9 years who were part of the Ewha Birth & Growth Cohort Study. BA was assessed by the Greulich-Pyle method. An index of BA advancement was calculated as the ratio of BA to chronological age (CA) (BA/CA), and this ratio was classified into 3 tertiles. We analyzed the relationship between BA advancement and anthropometric characteristics and adrenal hormone levels. The number of overweight children increased from the first group to the third group (P(Trend) = 0.03). The levels of adrenal androgens showed a significant positive correlation with the tertile groups after adjusting for age and sex (testosterone: r = 0.26, P < 0.001; dehydroepiandrosterone: r = 0.21, P < 0.001; androstenedione: r = 0.20, P < 0.001). Further, after controlling for body mass index (BMI), sex, and age, the BA/CA was found to be positively correlated with androstenedione (β = 0.04, R² = 3.7%) and testosterone levels (β = 0.05, R² = 4.7%). Based on our results, it is suggested that adrenal androgen levels are associated with BA advancement independent of BMI.

Abstract
After the introduction of replacement therapy with glucocorticoids and mineralocorticoids in the 1950s, congenital adrenal hyperplasia (CAH) is no longer a life-limiting condition. However, due to the successful introduction of medical steroid hormone replacement, CAH has become a chronic condition, with associated comorbidities and long-term health implications. The aim of treatment is the replacement of mineralocorticoids and glucocorticoids and the normalisation of elevated androgen concentrations. Long-term consequences of the condition and current treatment regimens include unfavourable changes in the cardiovascular risk profile, impaired growth, testicular adrenal rest tumours (TART) in male and subfertility in both male and female patients with CAH. Optimising replacement therapy in patients with CAH remains challenging. On one hand, treatment with supraphysiological doses of glucocorticoids might be required to normalise androgen concentrations and decrease size or presence of TARTs. On the other hand, treatment with supraphysiological doses of glucocorticoids is associated with an increased prevalence of unfavourable cardiovascular and metabolic risk profiles as well as impaired longitudinal growth and gonadal function. Therefore, treatment of children and adults with CAH requires an individualised approach. Careful monitoring for early signs of complications is already warranted during paediatric healthcare provision to prevent and reduce the impact of comorbidities in later life.

Abstract
Testicular tumor of adrenogenital syndrome is a rare and benign anomaly usually presenting as bilateral testicular masses. It is the most important cause of infertility in adult male congenital adrenal hyperplasia. Distinction between testicular tumors of adrenogenital syndrome and Leydig cell tumors can be problematic; it is based on clinical, histopathologic, immunohistochemical and endocrine features. Biopsy is advised in cases of longstanding tumors in infertile patients and when surgery is indicated. Fertility preservation is a key management goal in testicular tumor of adrenogenital syndrome. In stages 2 and 3, intensified glucocorticoid treatment is recommended as a first step treatment. Sparing surgical approach is preferred for tumors of stage 4 and steroid unresponsive masses. Magnetic resonance imaging is recommended before surgery. The only indication of surgery in stage 5 is testicular pain.

Abstract
Introduction Androstenedione (A4) is an adrenal and gonadal steroid biomarker, useful in the assessment of children in whom steroidogenic disorders are suspected. The first key step in the evaluation of a diagnostic test resides on confident reference intervals (RI). The lack of updated A4-RI with current methods in pediatrics may mislead A4 results and limit its diagnosis accuracy. Aim To provide A4 reference ranges in healthy children. Methods Prospective, descriptive study. 283 children aged 4 days to 18 years were included. In children < 1 yr, A4 was measured directly in serum (NE-A4) and postorganic solvent extraction (E-A4) for the assessment of interfering steroids. The influence of chronological age (CA), gender, and Tanner stage (T) were investigated. Results In the neonatal period, E-A4 was significantly lower than NE-A4; boys had higher NE-A4; sexual dimorphism disappeared after extraction procedure. In children older than 4 months, A4 concentration remained low until the age of 5 years. Thereafter, A4 increased significantly in association with CA and T (r2 = 0.65; p < 0.001), obtaining the highest concentrations in children within pubertal ages without sexual dimorphism. Conclusion We recommend to perform solvent extraction in neonates and to take into account age and sexual development to properly interpret A4 results in childhood.

Abstract
BACKGROUND High level of androgens found in congenital adrenal hyperplasia (CAH) seems to have a deleterious effect on heart function. We therefore evaluate cardiac function of children with CAH in comparison with a healthy group. METHODS We carried out a case-control study in the single endocrinology unit of the Mother and Child Center of Chantal Biya's Foundation. Cases were matched for age and genotypic sex to 2 healthy controls. We analyzed the ejection fraction (LVEF), fractional shortening and left ventricular mass; output and cardiac index; E and A waves velocities, E/A ratio and the mitral deceleration time and diameter of the left atrium; tricuspid annular plane systolic excursion and pulmonary artery systolic pressure were also measured. RESULTS We included 19 patients with a median age of 6.26 ± 3.75 years and 38 controls stackable distribution. The left ventricular mass of cases was greater than that of controls. A case of reversible cardiomyopathy on hormone replacement therapy was found. For the cases, the average ejection fraction was 71.95 ± 7.88%; the average fractional shortening was 40.67 ± 7.02%. All these values were higher than those of controls, although the difference was not statistically significant. Diastolic left ventricular function was more impaired among the cases. Right ventricular function was similar in both groups. These abnormalities were highly correlated to the late age at diagnosis and duration of treatment. CONCLUSION This study shows an altered cardiac function in CAH compared to healthy control and highlights importance of an early diagnosis of cases, a tight control of androgens levels and a regular monitoring of cardiac function.

Variations in the 3'UTR of the CYP21A2 Gene in Heterozygous Females with Hyperandrogenaemia. Int J Endocrinol 2017; 2017:8984365. [PMID: 28487735 PMCID: PMC5405599 DOI: 10.1155/2017/8984365] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2016] [Revised: 10/25/2016] [Accepted: 12/20/2016] [Indexed: 01/18/2023] Open
Abstract
Heterozygosity for CYP21A2 mutations in females is possibly related to increased risk of developing clinical hyperandrogenism. The present study was designed to seek evidence on the phenotype-genotype correlation in female children, adolescents, and women with CYP21A2 mutations and variants in the 3'UTR region of the gene. Sixty-six patients out of the 169 were identified as carriers of CYP21A2 mutations. Higher values of stimulated 17 hydroxyprogesterone (17-OHP) levels were found in the carriers of the p.Val281Leu mutation compared to the carriers of other mutations (mean: 24.7 nmol/l versus 15.6 nmol/l). The haplotype of the ∗52C>T, ∗440C>T, and ∗443T>C in the 3'UTR was identical in all heterozygous patients with p.Val281Leu and the haplotype of the ∗12C>T and ∗52C>T was identical in all heterozygous patients with the p.Gln318∗. In conclusion, hyperandrogenaemic females are likely to bear heterozygous CYP21A2 mutations. Carriers of the mild p.Val281Leu mutation are at higher risk of developing hyperandrogenism than the carriers of more severe mutations. The identification of variants in the 3'UTR of CYP21A2 in combination with the heterozygous mutation may be associated with the mild form of nonclassic congenital adrenal hyperplasia and reveal the importance of analyzing the CYP21A2 untranslated regions for the appropriate management of this category of patients.

Abstract
UNLABELLED Patients with congenital adrenal hyperplasia (CAH) appear to have adverse cardiovascular risk profile and other long-term health problems in adult life, but there are limited data in young CAH patients. We aim to evaluate the cardio-metabolic risk factors in adolescents and young adults with classical 21-hydroxylase deficiency (21-OHD). We performed a cross-sectional study of 21 patients (17 females) with classic CAH detected clinically and not through newborn screening, aged 15.2 ± 5.8 years, and 21 healthy matched controls. Anthropometric, biochemical, inflammatory markers, and body composition using dual-energy X-ray absorptiometry were measured. Obesity was observed in 33% of the CAH patients. The waist/hip ratio and waist/height ratio were significantly higher in CAH patients. Five out of 21 patients (24%) had elevated blood pressure. Silent diabetes was diagnosed in one patient (4.8%), but none in the control group. Serum leptin and interleukin-6 levels were not different between groups, but hs-CRP levels tended to be higher in CAH patients. Other metabolic profiles and body composition were similar in CAH and controls. CONCLUSION Adolescents and young adults with CAH appear to have an increased risk of obesity and cardio-metabolic risk factors. Close monitoring, early identification, and secondary prevention should be implemented during pediatric care to improve the long-term health outcomes in CAH patients. What is Known: • Lifelong glucocorticoid (GC) replacement is the main treatment modality in patients with congenital adrenal hyperplasia which predispose to an adverse metabolic profile. • Adult CAH patients have adverse cardiovascular risk profile and other long-term health problems. What is New: • Adolescents and young adults with CAH appear to have an increased risk of obesity and cardio-metabolic risk factors.

Abstract
Steroid 21-hydroxylase deficiency is the most prevalent form of congenital adrenal hyperplasia (CAH), accounting for approximately 95% of cases. With the advent of newborn screening and hormone replacement therapy, most children with CAH survive into adulthood. Adolescents and adults with CAH experience a number of complications, including short stature, obesity, infertility, tumor, osteoporosis, and reduced quality of life. Transition from pediatric to adult care and management of long-term complications are challenging for both patients and health-care providers. Psychosocial issues frequently affect adherence to glucocorticoid treatment. Therefore, the safe transition of adolescents to adult care requires regular follow-up of patients by a multidisciplinary team including pediatric and adult endocrinologists. The major goals for management of adults with 21-hydroxylase deficiency are to minimize the long-term complications of glucocorticoid therapy, reduce hyperandrogenism, prevent adrenal or testicular adrenal rest tumors, maintain fertility, and improve quality of life. Optimized medical or surgical treatment strategies should be developed through coordinated care, both during transition periods and throughout patients' lifetimes. This review will summarize current knowledge on the management of adults with CAH, and suggested appropriate approaches to the transition from pediatric to adult care.

Abstract
The abundant adrenal C19 steroid 11β-hydroxyandrostenedione (11OHA4) has been written off as a dead-end product of adrenal steroidogenesis. However, recent evidence has demonstrated that 11OHA4 is the precursor to the potent androgenic 11-oxygenated steroids, 11-ketotestosterone and 11-ketodihydrotestosterone, that bind and activate the human androgen receptor similarly to testosterone and DHT. The significance of this discovery becomes apparent when considering androgen dependent diseases such as castration resistant prostate cancer and diseases associated with androgen excess, e.g. congenital adrenal hyperplasia and polycystic ovary syndrome. In this review we describe the production and metabolism of 11-oxygenated steroids. We subsequently discuss their androgenic activity and highlight the putative role of these androgens in disease states.

Abstract
Congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency is a rare autosomal recessive genetic disorder. It is caused by reduced or absent activity of 11β-hydroxylase (CYP11B1) enzyme and the resultant defects in adrenal steroidogenesis. The most common clinical features of 11 beta-hydroxylase deficiency are ambiguous genitalia, accelerated skeletal maturation and resultant short stature, peripheral precocious puberty and hyporeninemic hypokalemic hypertension. The biochemical diagnosis is based on raised serum 11-deoxycortisol and 11-deoxycorticosterone levels together with increased adrenal androgens. More than 100 mutations in CYP11B1 gene have been reported to date. The level of in-vivo activity of CYP11B1 relates to the degree of severity of 11 beta-hydroxylase deficiency. Clinical management of 11 beta-hydroxylase deficiency can pose a challenge to maintain adequate glucocorticoid dosing to suppress adrenal androgen excess while avoiding glucocorticoid-induced side effects. The long-term outcomes of clinical and surgical management are not well studied. This review article aims to collate the current available data about 11 beta-hydroxylase deficiency and its management.

Abstract
11β-Hydroxylase deficiency is the second most frequent type of congenital adrenal hyperplasia and is more common in those of Turkish descent than in other populations. The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish patients with 11β-hydroxylase deficiency. Twenty-eight patients from 24 families, ages ranging from 0.1 to 7 years, were included in the study. Clinical diagnosis was based on virilization and high levels of 11-deoxycortisol. Twenty-six cases exhibited the classical and 2 cases the non-classical form. Mutation screening of 9 CYP11B1 exons was performed by direct DNA sequence analysis, specifically amplifying CYP11B1 gene fragments while avoiding simultaneous amplification of homologous CYP11B2 gene sequences. Seventeen different mutations were detected, 6 of which are novel (p.Gln189Hisfs*70, p.Glu198Gly, p.Thr318Lys, p.Gly446Ser, IVS8+5G>C and exon 3-5 del). All of the identified mutations resulted in the classical form with severe virilization, except for the p.Gly446Ser mutation, which caused a late-onset type of 11β-hydroxylase deficiency. The c.954G>A;p.Thr318Thr mutation was the most common in our cohort, with an allele frequency of 14.6%.Of the CYP11B1 gene mutations detected, 75% were found in exons 3, 5 and 7 and the half of the mutations were nonsense, splice site, deletion or insertion mutations, causing severe virilization in female patients. The findings are important for genetic counseling and the prenatal diagnosis of Turkish patients with 11β-hydroxylase deficiency.

Abstract
Abstract. The digit ratio is a putative biomarker for evaluating the organizational effects of prenatal testosterone. This evaluation was performed by relating postnatal traits to digit ratio. We examined the relationship among digit ratio, depression, and positive/negative affect. A total of 335 university students who completed a set of questionnaires had both of their hands scanned, and the digit ratios were measured using a computer program. All the studied variables were insignificantly related to the right-hand digit ratio. The variables remained insignificant even when the data for males and females were analyzed separately. Furthermore, a meta-analysis, including a previous study combined with current data, showed no association between digit ratio and depression, although the current sample size of 355 could detect r = 0.2 at α = 0.05, and β = 0.2. The lack of association between digit ratio and depression was common, and the present results corroborated those of previous studies, which showed no association between digit ratio and depression. This nil result would be least likely attributable to an inadequate sample size, considering that the current sample size of 335 allowed the detection of r = 0.2 at α = 0.05 and β = 0.2, nor idiosyncratic results, given that the meta-analysis with previous relevant studies also concluded the same results. We extensively reviewed the relevant literature and evaluated the use of digit ratio as a biomarker for prenatal testosterone exposure in seven different perspectives. Nearly all the analysis showed the problems of using digit ratio as a biomarker for evaluating the organizational effect of prenatal hormones.

Abstract
Congenital adrenal hyperplasia (CAH) refers to a group of inherited genetic disorders involving deficiencies in enzymes that convert cholesterol to cortisol within the adrenal cortex. There are five key enzymes involved in the production of cortisol. Of these key enzymes, deficiency of 21-hydroxylase is the most commonly defective enzyme leading to CAH representing more than 90% of cases. The low adrenal cortisol levels associated with CAH affects the hypothalamic-pituitary-adrenal negative feedback system leading to increased pituitary adrenocorticotropic hormone (ACTH) production, which overstimulates the adrenal cortex in an attempt to increase cortisol production resulting in a hyperplastic adrenal cortex. The deficiency of enzyme 21-hydroxylase results from mutations or deletions in the CYP21A2 gene found on chromosome 6p. The disorder is transmitted as an autosomal recessive pattern and specific mutations may be correlated to enzymatic compromise of varying degrees, leading to the clinical manifestation of 21-hydroxylase deficiency (21-OHD) CAH.

Abstract
CYP21A2 mutation analysis of congenital adrenal hyperplasia (CAH) is challenging because of the genomic presence of a homologous CYP21A2 pseudogene and the significant incidence of pseudogene conversion and large deletions. The objective of this study was to accurately analyze the CYP21A2 genotype in Korean CAH patients using a combination of complementary methods. Long-range PCR and restriction fragment length polymorphism analyses were performed to confirm valid amplification of CYP21A2 and to detect large gene conversions and deletions before direct sequencing. Multiple ligation-dependent probe amplification (MLPA) analysis was conducted concurrently in 14 CAH-suspected patients and six family members of three patients. We identified 27 CYP21A2 mutant alleles in 14 CAH-suspected patients. The c.293-13A>G (or c.293-13C>G) was the most common mutation, and p.Ile173Asn was the second, identified in 25% and 17.9% of alleles, respectively. A novel frame-shift mutation of c.492delA (p.Glu 164Aspfs*24) was detected. Large deletions were detected by MLPA in 10.7% of the alleles. Mutation studies of the six familial members for three of the patients aided in the identification of haplotypes. In summary, we successfully identified CYP21A2 mutations using both long-range PCR and sequencing and dosage analyses. Our data correspond relatively well with the previously reported mutation spectrum analysis.

Abstract
21-hydroxylase deficiency (21-OHD) is the most common type of congenital adrenal hyperplasia. In addition to the clinical problems caused by adrenal insufficiency and androgen excess, a risk for obesity and metabolic syndrome during young adulthood is a major ramification of the disease. Although glucocorticoid therapy is very likely to be one of the contributory factors, the precise causes of the metabolic status of adult 21-OHD patients remain to be clarified. Previously we reported that 21-OHD patients developed early onset AR, a condition which might create a risk for obesity and metabolic syndrome in adulthood. In order to elucidate the association between the onset of AR and factors during the fetal period to early infancy, we conducted a retrospective longitudinal analysis of 29 21-OHD patients (male: 14 cases, female: 15 cases, salt wasting type: 16, simple virilizing type: 13), who were identified by newborn screening and followed up at least until the age 10 years. Body size at birth, lower body weight, and lower BMI were found to precipitate the timing of AR. On the other hand, no significant association was observed between the timing of AR and sex, gestational age, treatment regimen (including cumulative dose of HDC), and disease severity (the type of the disease, the value of DHEA-S and 17-OHP). There are two points to consider: first, in 21-OHD patients treated with glucocorticoid substitution therapy, the risk for early AR cannot be reduced by adjusting the dose of glucocorticoid; second, fetal factors might affect the metabolic status of 21-OHD patients.

Abstract
Congenital Adrenal Hyperplasia (CAH) is a common autosomal recessive disorder of the adrenal steroidogenic pathway. The most common form of CAH is due to mutations in CYP21A2 gene. The incidence of mutations in the CYP21A2 gene and the genotype-phenotype correlations vary among different populations. Therefore, the aim of the study was to establish the spectrum of mutations and to evaluate genotype-phenotype correlation in Indian CAH population. Molecular defects were investigated in 110 alleles (55 patients) in the present study. Notably, we identified disease causing mutations in 106 of 110 (96.4%) alleles whereas the frequency of undetectable mutations was 3.6%. The i2g mutation (20%) was found to be the most common in CAH patients. The second most common mutation was p.R356W (14.5%). p.I172N and 8-bp deletion in exon 3 accounted for 12.7% of the mutated alleles. In descending order, the other mutations present were p.Q318X (9%), E6 Cluster (5.4%), p.V281L (3.6%) and large gene deletion (3.6%). Additionally, p.P267L and frameshift mutation (L307fs/F306+T) were also detected in the Indian cohort with frequency of 1.8% and 5.4% respectively.rare mutation/rare mutations in the CYP21A2 gene were detected viz., p.D234D (NCBI accession number - KF812549), p.F306V (NCBI accession number - KF534754), p.P357P (NCBI accession number - KF692099) and p.H365N (NCBI accession number - KF447378). The genotypes of the patients were categorized into four groups null, A, B and C. Of note, correlation between genotype and phenotype is sufficiently strong, to be of clinical significance in the genetic counseling.

Abstract
Congenital adrenal hyperplasia (CAH) due to steroid 21-hydroxylase (21-OH) deficiency (21-OHD) is an autosomal recessive disorder, in which CYP21A2 mutations or deletions result in underproduction of glucocorticoid and mineralocorticoid, and overproduction of androgens. Patients with CAH are treated with oral steroid supplementation, but optimal control of blood steroid levels remains difficult. Thus, new therapeutic approaches are still needed. Previously, adenovirus-mediated administration of human CYP21A2 to adrenal glands rescued the phenotype of a mouse model of 21-OHD. In this study, we examined whether transduction of murine Cyp21a1 in extra-adrenal tissues could rescue steroid metabolism in 21-OHD mice. We transduced primary fibroblasts obtained from 21-OHD mice with a retroviral vector containing Cyp21a1. In vitro assays demonstrated that Cyp21a1-expressing fibroblasts can uptake progesterone from the culture media, convert it to deoxycorticosterone (DOC), and subsequently release DOC back into the media. Autotransplantation of Cyp21a1-expressing fibroblasts into the subcutaneous tissues of the back resulted in a significant reduction in the serum progesterone/DOC ratio in four of six 21-OHD mice at 4 weeks after injection. We also directly injected an adeno-associated viral vector containing Cyp21a1 into the thigh muscles of 21-OHD mice. Serum progesterone/DOC ratios were markedly reduced in all four animals at 4 weeks after injection. These results indicate that extra-adrenal induction of Cyp21a1 ameliorates steroid metabolism in 21-OHD mice. This study suggests a novel therapeutic strategy for congenital adrenal hyperplasia, which warrants further investigations.

Abstract
Mast cells are present in the human adult adrenal with a potential role in the regulation of aldosterone secretion in both normal cortex and adrenocortical adenomas. We have investigated the human developing adrenal gland for the presence of mast cells in parallel with steroidogenic enzymes profile and serotonin signaling pathway. RT-QPCR and immunohistochemical studies were performed on adrenals at 16-41 weeks of gestation (WG). Tryptase-immunopositive mast cells were found from 18 WG in the adrenal subcapsular layer, close to 3βHSD- and CYP11B2-immunoreactive cells, firstly detected at 18 and 24 WG, respectively. Tryptophan hydroxylase and serotonin receptor type 4 expression increased at 30 WG before the CYP11B2 expression surge. In addition, HDL and LDL cholesterol receptors were expressed in the subcapsular zone from 24 WG. Altogether, our findings suggest the implication of mast cells and serotonin in the establishment of the mineralocorticoid synthesizing pathway during fetal adrenal development.

Abstract
BACKGROUND Glucocorticoid replacement therapy in congenital adrenal hyperplasia (CAH) is challenging, especially in children, because both over- and under-dosing may have profound and long-lasting adverse effects. Clinical follow-up parameters are largely nonspecific and slow to develop. Steroid concentrations in scalp hair may be a useful monitoring tool, as it provides information on both long-term steroid precursor and glucocorticoid exposure. AIM We aimed to evaluate scalp hair steroid precursor concentrations as a monitoring tool for treatment follow-up in children with CAH. METHODS Scalp hair 17-hydroxyprogesterone (17-OHP) and androstenedione concentrations, measured by LC-MS/MS, of children with CAH (N = 26) were correlated with concentrations in serum and saliva, and compared to scalp hair concentrations in patient controls with adrenal insufficiency (AI) (N = 12) and healthy controls (N = 293). RESULTS Hair cortisol concentrations were higher in children with CAH, compared to both healthy controls (P < 0·001) and patient controls (P = 0·05), and did not differ significantly between patient controls with AI and healthy controls. Concentrations of androstenedione in scalp hair were strongly correlated with concentrations in serum (ρ = 0·72, P < 0·001) and saliva (ρ = 0·82, P = 0·002). This was also seen for 17-OHP in hair with serum (ρ = 0·94, P < 0·001) and saliva (ρ = 0·69, P = 0·009). Both hair 17-OHP and androstenedione were higher in CAH patients (mean concentration 17-OHP 2·9 pg/mg; androstenedione 1·3 pg/mg), when compared to healthy controls (17-OHP 0·44 pg/mg; androstenedione 0·65 pg/mg) and when compared to patients with AI (17-OHP 0·12 pg/mg; androstenedione 0·32 pg/mg). CONCLUSION This study shows that scalp hair 17-hydroxyprogesterone and androstenedione concentrations seem to be a promising parameter for treatment monitoring in patients with CAH.

Abstract
OBJECTIVE In contrast to the high incidence of testicular adrenal rest tumors in adult male patients with congenital adrenal hyperplasia (CAH), ovarian adrenal rest tumors (OARTs) in female CAH patients are rare. In this case report, we describe a case of bilateral OART in a female patient with CAH due to 21-hydroxylase deficiency. METHODS We present a detailed case report with the clinical, imaging, and laboratory findings of the patient. The pertinent literature is also reviewed. RESULTS A 17-year-old patient was known to have CAH due to 21-hydroxylase deficiency. Since the second month of her gestational age, her mother was treated with cortisone-replacement therapy. The patient was treated with hydrocortisone and fludrocortisone since the neonatal period. Her pertinent history included a bilateral adrenalectomy at the age of 13 years in 2006, and for 3 years she led a normal puberty life with no complaint with hormonal replacement therapy. Nevertheless, in 2009, she developed a virilizing syndrome. Subsequently, she underwent surgery in December 2009 for right adnexectomy. However, the regression of the masculinizing mass was not complete and worsened several months after the surgery. A new pelvic magnetic resonance image showed the activation of a contralateral ovarian mass, necessitating a left adnexectomy in August 2010. CONCLUSION This case demonstrates some interesting features of OART that pose challenges to its management. If an OART is detected early enough and glucocorticoid therapy is received, it is possible that the OART will decrease in size following suppression of adrenocorticotropic hormone levels.

Abstract
PURPOSE OF REVIEW In recent years, important steps have been taken to improve the treatment of congenital adrenal hyperplasia (CAH), a relatively stagnant area for decades. In this review, we summarize these advances and propose future lines of investigation. RECENT FINDINGS The two main goals of CAH treatment are to replace the deficient hormones when necessary and to dampen the adrenocorticotropin activation and the ensuing adrenal androgen excess. Glucocorticoids have been the mainstay of CAH treatment, but available preparations only partially meet the clinical needs. Recent efforts have focused on improving the delivery of glucocorticoid replacement agents, to closer mimic the physiologic secretion pattern. Examples include modified release oral glucocorticoids and continuous subcutaneous hydrocortisone pumps. Furthermore, nonglucocorticoid approaches to address the androgen excess have emerged, such as inhibition of key androgenic enzymes and adrenocorticotropin secretion blockade by corticotropin-releasing hormone receptor antagonists. SUMMARY The promising recent progress made in CAH treatment brings new perspectives for individualized care in this complex disease.

Abstract
Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

Abstract
OBJECTIVE To comprehensively characterize androgens and androgen precursors in classic 21-hydroxylase deficiency (21OHD) and to gain insights into the mechanisms of their formation. DESIGN Serum samples were obtained from 38 patients (19 men) with classic 21OHD, aged 3-59, and 38 sex- and age-matched controls; 3 patients with 11β-hydroxylase deficiency; 4 patients with adrenal insufficiency; and 16 patients (8 men) undergoing adrenal vein sampling. Paraffin-embedded normal (n = 5) and 21OHD adrenal tissues (n = 3) were used for immunohistochemical studies. METHODS We measured 11 steroids in all sera by liquid chromatography-tandem mass spectrometry. Immunofluroescence localized 3β-hydroxysteroid dehydrogenase type 2 (HSD3B2) and cytochrome b5 (CYB5A) within the normal and 21OHD adrenals. RESULTS Four 11-oxygenated 19-carbon (11oxC19) steroids were significantly higher in male and female 21OHD patients than in controls: 11β-hydroxyandrostenedione, 11-ketoandrostenedione 11β-hydroxytestosterone, and 11-ketotestosterone (3-4-fold, P < 0.0001). For 21OHD patients, testosterone and 11-ketotestosterone were positively correlated in females, but inversely correlated in males. All 11oxC19 steroids were higher in the adrenal vein than in the inferior vena cava samples from men and women and rose with cosyntropin stimulation. Only trace amounts of 11oxC19 steroids were found in the sera of patients with 11β-hydroxylase deficiency and adrenal insufficiency, confirming their adrenal origin. HSD3B2 and CYB5A immunoreactivities were sharply segregated in the normal adrenal glands, whereas areas of overlapping expression were identified in the 21OHD adrenals. CONCLUSIONS All four 11oxC19 steroids are elevated in both men and women with classic 21OHD. Our data suggest that 11oxC19 steroids are specific biomarkers of adrenal-derived androgen excess.

Abstract
Background: Congenital adrenal hyperplasia (CAH) due to mutations in the gene encoding 21-hydroxilase is one of common disease with an autosomal recessive form. In this study, our aim is to detect the prevalence of eight common mutations in nonclassical congenital adrenal hyperplasia (NCAH). Materials and Methods: A total of 30 patients with clinical and laboratory evidence of NCAH was selected. Gene-specific polymerase chain reaction (PCR) without contamination of pseudogene was carried out, and PCR product of this step was used to amplification-refractory mutation system PCR on eight common mutations in CYP21A2 gene. Results: Two heterozygote patients for I2G mutation and six heterozygote patients for Q318X mutation is reported in our study. These mutations associated with the classic form of CAH, and heterozygotes presented with NC symptom, including premature pubarche and hirsutism. Conclusion: There are some data about the association of the mutation with the clinical form of CAH including classic (salt-wasting and simple virilizing) and NC form. I2G and Q318X mutations were reported in classic form in homozygote state, but the heterozygote form associated with NC form. CAH diagnosis with NC symptom and with measurement of 17-hydroxyprogestrone as NCAH is not a trusted assessment and require to molecular analysis for accurate diagnosis.

Abstract
Steroid 21-hydroxylase deficiency (21-OHD) caused by the CYP21A2 gene mutations accounts for more than 90% of congenital adrenal hyperplasia (CAH) cases. In this study, molecular defects of 230 patients with 21-OHD were investigated. Point mutations of CYP21A2 gene were analyzed by Sanger sequencing, and large gene deletions were detected by multiplex ligation-dependent probe amplification (MLPA). Nine micro-conversions and 18 spontaneous mutations accounted for 74.6% of alleles, while large gene deletions and large gene conversions accounted for 25.4% of alleles. The most frequent micro-conversion was c.292-13A/C>G (I2G) (35%), followed by p.I173N (14.3%), p.R357W (5.9%) and p.Q319* (4.6%). Nine novel mutations were identified in these patients, which were predicted to hamper the 21-hydroxylase protein function in varying degrees. Genotype and phenotype correlated well in 89.6% of our patients, but disparity in phenotypic appearance also appeared in a small portion of the patients. 16.1% of the patients carried homozygous genotypes while 83.9% of patients carried compound heterozygous mutations. We concluded that the frequency of CYP21A2 mutations in our study was slightly different from those reported for other ethnic groups. Micro-conversions were the main category of the mutation spectrum, while large deletions and large gene conversions could also cause 21-OHD. A large portion of different types of the compound heterozygous genotypes may partially contribute to the discordance in genotype-phenotype comparison. This study expanded the CYP21A2 mutation spectrum of Chinese patients and could be helpful in prenatal diagnosis and genetic counseling for 21-OHD patients.

A Case of Bilateral Testicular Tumors Subsequently Diagnosed as Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2016; 9:574-80. [PMID: 26985347 PMCID: PMC4793180 DOI: 10.22074/ijfs.2015.4618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2014] [Accepted: 09/16/2014] [Indexed: 11/28/2022]
Abstract
21-hydroxylase deficiency (21-OHD) caused congenital adrenal hyperplasia (CAH) is a
group of autosomal recessive genetic disorders resulting from mutations in genes involved
with cortisol (CO) synthesis in the adrenal glands. Testicular adrenal rest tumors (TARTs)
are rarely the presenting symptoms of CAH. Here, we describe a case of simple virilizing
CAH with TARTs, in a 15-year-old boy. The patient showed physical signs of precocious
puberty. The levels of blood adrenocorticotropic hormone (ACTH), urinary 17-ketone
steroids (17-KS), dehydroepiandrosterone sulfate (DHEA-S), and serum progesterone
(PRGE) were elevated, whereas those of follicle-stimulating hormone (FSH), luteinizing
hormone (LH), and CO were reduced. Computed tomography (CT) of the adrenal glands
and magnetic resonance imaging (MRI) of the testes showed a soft tissue density (more
pronounced on the right side) and an irregularly swollen mass (more pronounced on the
left side), respectively. Pathological examination of a specimen of the mass indicated
polygonal/circular eosinophilic cytoplasm, cord-like arrangement of interstitial cells, and
lipid pigment in the cytoplasm. Immunohistochemistry results precluded a diagnosis of
Leydig cell tumors. DNA sequencing revealed a hackneyed homozygous mutation, I2g,
on intron 2 of the CYP21A2 gene. The patient’s symptoms improved after a three-month
of dexamethasone therapy. Recent radiographic data showed reduced hyperplastic adrenal nodules and testicular tumors. A diagnosis of TART should be considered and prioritized in CAH patients with testicular tumors. Replacement therapy using a sufficient
amount of dexamethasone in this case helps combat TART.

Single-Dose Study of a Corticotropin-Releasing Factor Receptor-1 Antagonist in Women With 21-Hydroxylase Deficiency. J Clin Endocrinol Metab 2016; 101:1174-80.

Abstract
CONTEXT Treatment of 21-hydroxylase deficiency (21OHD) is difficult to optimize. Normalization of excessive ACTH and adrenal steroid production commonly requires supraphysiologic doses of glucocorticoids. OBJECTIVES We evaluated the safety and tolerability of the selective corticotropin releasing factor type 1 (CRF1) receptor antagonist NBI-77860 in women with classic 21OHD and tested the hypothesis that CRF1 receptor blockade decreases early-morning ACTH and 17α-hydroxyprogesterone (17OHP) in these patients. PARTICIPANTS The study enrolled eight classic 21OHD females, ages 18-58 years, seen at a single tertiary referral university setting. DESIGN This was a phase Ib, single-blind, placebo-controlled, fixed-sequence, single-dose trial. During three treatment periods separated by 3-week washout intervals, patients sequentially received placebo, NBI-77860 300 mg, and NBI-77860 600 mg at 10 pm; glucocorticoid therapy was withheld for 20 hours. We evaluated ACTH, 17OHP, androstenedione, and testosterone as well as NBI-77860 pharmacokinetics over 24 hours. RESULTS Dose-dependent reductions of ACTH and/or 17OHP were observed in six of eight subjects. Relative to placebo, NBI-77860 led to an ACTH and 17OHP reduction by a mean of 43% and 0.7% for the 300 mg dose, respectively, and by 41% and 27% for the 600 mg dose, respectively. Both NBI-77860 doses were well tolerated. CONCLUSION The meaningful reductions in ACTH and 17OHP following NBI-77860 dosing in 21OHD patients demonstrate target engagement and proof of principle in this disorder. These promising data provide a rationale for additional investigations of CRF1 receptor antagonists added to physiologic doses of hydrocortisone and fludrocortisone acetate for the treatment of classic 21OHD.

Abstract
The term congenital adrenal hyperplasia (CAH) covers a group of autosomal recessive disorders caused by defects in one of the steroidogenic enzymes involved in the synthesis of cortisol or aldosterone from cholesterol in the adrenal glands. Approximately 95% of all CAH cases are caused by 21-hydroxylase deficiency encoded by the CYP21A2 gene. The disorder is categorized into classical forms, including the salt-wasting and the simple virilizing types, and nonclassical forms based on the severity of the disease. The severity of the clinical features varies according to the level of residual 21-hydroxylase activity. Newborn screening for CAH is performed in many countries to prevent salt-wasting crises in the neonatal period, to prevent male sex assignment in affected females, and to reduce long-term morbidities, such as short stature, gender confusion, and psychosexual disturbances. 17α-hydroxyprogesterone is a marker for 21-hydroxylase deficiency and is measured using a radioimmunoassay, an enzyme-linked immunosorbent assay, or a fluoroimmunoassay. Recently, liquid chromatography linked with tandem mass spectrometry was developed for rapid, highly specific, and sensitive analysis of multiple analytes. Urinary steroid analysis by gas chromatography mass spectrometry also provides qualitative and quantitative data on the excretion of steroid hormone metabolites. Molecular analysis of CYP21A2 is useful for genetic counseling, confirming diagnosis, and predicting prognoses. In conclusion, early detection using neonatal screening tests and treatment can prevent the worst outcomes of 21-hydroxylase deficiency.

Abstract
PURPOSE 11β-Hydroxylase deficiency (11OHD) represents the second most common cause of congenital adrenal hyperplasia. It is caused by mutations in the CYP11B1 gene localized about 40 kb from the CYP11B2 gene with which it shares a homology of 95 %. The asymmetric recombination of these two genes is involved both in 11OHD and in glucocorticoid-remediable aldosteronism (GRA). Our objective was to set up an easy and rapid method to detect these hybrid genes and other kinds of deletions, to improve the molecular diagnosis of 11OHD. METHODS A set of 8 specific probes for both the CYP11B1 and the CYP11B2 genes to be used for multiplex ligation-dependent probe amplification (MLPA) analysis was designed to detect rearrangements of these genes. RESULTS The method developed was tested on 15 healthy controls and was proved to be specific and reliable; it led us to identify a novel chimeric CYP11B2/CYP11B1 gene in one patient that carried the known A306V mutation on the other allele. Specific amplification and sequencing of the hybrid gene confirmed the breakpoint localization in the second intron. CONCLUSIONS The MLPA kit developed enables the detection of deletions, duplications or chimeric genes and represents an optimal supplement to DNA sequence analysis in patients with 11OHD. In addition, it can also be used to show the presence of the opposite chimaera associated with GRA.
