J Clin Endocrinol Metab 2024; 109:e1175-e1184. [PMID: 37862468 PMCID: PMC10876393 DOI: 10.1210/clinem/dgad624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 10/05/2023] [Accepted: 10/18/2023] [Indexed: 10/22/2023]
Abstract
CONTEXT It has been suggested that injuries and accidents are increased in females with congenital adrenal hyperplasia (CAH), but the prevalence is unclear. OBJECTIVE To study the prevalence of injuries and accidents in females and males with CAH. DESIGN, SETTING, AND PARTICIPANTS Patients with CAH (n = 714, all 21-hydroxylase deficiency) were compared with matched controls (n = 71 400). Data were derived by linking National Population-Based Registers. MAIN OUTCOME MEASURES Prevalence of injuries and accidents. RESULTS Mean age was 29.8 ± 18.4 years. Injuries were more prevalent in patients with CAH than in controls (relative risk, 1.34; 95% CI, 1.24-1.44), and this was found in both sexes (females: 1.43; 1.29-1.58; males: 1.25; 1.12-1.38). In the classical phenotype, the prevalence of injuries was higher, especially in females but not in the nonclassic phenotype. In the genotype groups, injuries were mainly increased in females. Head injuries were increased in all patients with CAH and in the different phenotypes and were mainly driven by females. More patients with CAH born before the introduction of neonatal screening had had an injury compared with controls (1.48; 1.35-1.62); this was seen in both sexes. In patients with CAH born after the introduction of screening, the prevalence of injuries was overall increased (1.20; 1.07-1.35), and in females with CAH but not in males. Accidents showed a similar pattern to injuries in all comparisons. CONCLUSION Patients with CAH had an increased prevalence of both injuries and accidents, especially in females and in those born before the neonatal screening program. Patients with nonclassic phenotype were hardly affected.

Abstract
PURPOSE Congenital adrenal hyperplasia (CAH) has been associated with adrenal tumors (ATs) but the relationship is still unclear. The aim was to investigate if CAH was more common in patients with adrenal tumors and their characteristics. METHODS Using national registers all patients with an AT diagnosis (cases) and selected matched controls without AT diagnosis were included from 1st January 2005 to 31st December 2019. The patients with a CAH diagnosis were scrutinized in detail. RESULTS ATs were diagnosed in 26,573 individuals and in none of 144,124 controls. In 20 patients with ATs and 1 control, a CAH diagnosis was present. The odds for having CAH in patients with ATs was 109 (95% CI 15-809; P < 0.0001). Among cases, 5 had a CAH diagnosis before the discovery of ATs and 15 afterwards. Half were females and two had been screened for CAH neonatally. The mean age when the ATs was discovered was 55.6 years. Adrenalectomy was performed in seven patients. Five patients had unilateral adrenalectomy before the CAH diagnosis and did not have any glucocorticoid protection. After the CAH diagnosis, 15 were initiated on glucocorticoids and 6 on mineralocorticoids. The majority diagnosed with CAH before index date had classic CAH. In individual diagnosed after index date, only three had classic CAH. The rest had nonclassical CAH. During the follow-up time of 9 years, six deceased, two of them in an adrenal crisis. CONCLUSIONS The prevalence of CAH was greater in patients with ATs than in patients without. In all patients with ATs, CAH should be considered.

Abstract
A plethora of negative long-term outcomes have been associated with congenital adrenal hyperplasia (CAH). The causes are multiple and involve supra-physiological gluco- and mineralocorticoid replacement, excess adrenal androgens both intrauterine and postnatal, elevated steroid precursor and adrenocorticotropic hormone levels, living with a congenital condition as well as the proximity of the cytochrome P450 family 21 subfamily A member 2 (CYP21A2) gene to other genes. This review aims to discuss the different long-term outcomes of CAH.

Abstract
The term CAH-X was coined to describe a subset of patients with 21-hydroxylase deficiency displaying a phenotype compatible with the hypermobility type of Ehlers Danlos syndrome. The genetic defect is due to the monoallelic presence of a CYP21A2 deletion extending into the gene encoding tenascin X (TNXB), a connective tissue extracellular matrix protein. The result is a chimeric TNXA/TNXB gene causing tenascin-X haploinsufficiency. The prevalence of CAH-X was estimated to be around 14-15% in large cohorts of patients with 21-hydroxylase deficiency. However, population studies are still scarce and the clinical picture of the syndrome has yet to be fully defined. In this review, we discuss the current knowledge regarding the genetic and clinical profile of the CAH-X syndrome.

Abstract
Adrenal insufficiency in paediatric patients is mostly due to congenital adrenal hyperplasia (CAH), a severe monogenic disease caused by steroid 21-hydroxylase deficiency (21-OHD, encoded by the CYP21A2 gene) in 95% of cases. CYP21A2 genotyping requires careful analyses that guaranty gene-specific PCR, accurate definition of pseudogene-gene chimeras, gene duplications and allele dropout avoidance. A small panel of well-established disease-causing alterations enables a high diagnostic yield in confirming/discarding the disorder not only in symptomatic patients but also in those asymptomatic with borderline/positive results of 17-hydroxyprogesterone. Unfortunately, the complexity of this locus makes it today reluctant to high throughput techniques of massive sequencing. The strong relationship existing between the molecular alterations and the degree of enzymatic deficiency has allowed genetic studies to demonstrate its usefulness in predicting/classifying the clinical form of the disease. Other aspects of interest regarding molecular studies include its independence of physiological variations and analytical interferences, its usefulness in the diagnosis of simple virilizing forms in males and its inherent contribution to the genetic counseling, an aspect of great importance taking into account the high carrier frequency of CAH in the general population. Genetic testing of CYP21A2 constitutes an irreplaceable tool to detect severe alleles not just in family members of classical forms but also in mild late-onset forms of the disease and couples. It is also helpful in areas such as assisted reproduction and preimplantation diagnosis. Molecular diagnosis of 21-OHD under expert knowledge definitely contributes to a better management of the disease in every step of the clinical course.

[PMID: 35288842 PMCID: PMC8920443 DOI: 10.1007/s12022-022-09710-8] [Citation(s) in RCA: 78] [Impact Index Per Article: 39.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/12/2022] [Indexed: 12/13/2022]
Abstract
The new WHO classification of adrenal cortical proliferations reflects translational advances in the fields of endocrine pathology, oncology and molecular biology. By adopting a question-answer framework, this review highlights advances in knowledge of histological features, ancillary studies, and associated genetic findings that increase the understanding of the adrenal cortex pathologies that are now reflected in the 2022 WHO classification. The pathological correlates of adrenal cortical proliferations include diffuse adrenal cortical hyperplasia, adrenal cortical nodular disease, adrenal cortical adenomas and adrenal cortical carcinomas. Understanding germline susceptibility and the clonal-neoplastic nature of individual adrenal cortical nodules in primary bilateral macronodular adrenal cortical disease, and recognition of the clonal-neoplastic nature of incidentally discovered non-functional subcentimeter benign adrenal cortical nodules has led to redefining the spectrum of adrenal cortical nodular disease. As a consequence, the most significant nomenclature change in the field of adrenal cortical pathology involves the refined classification of adrenal cortical nodular disease which now includes (a) sporadic nodular adrenocortical disease, (b) bilateral micronodular adrenal cortical disease, and (c) bilateral macronodular adrenal cortical disease (formerly known primary bilateral macronodular adrenal cortical hyperplasia). This group of clinicopathological entities are reflected in functional adrenal cortical pathologies. Aldosterone producing cortical lesions can be unifocal or multifocal, and may be bilateral with no imaging-detected nodule(s). Furthermore, not all grossly or radiologically identified adrenal cortical lesions may be the source of aldosterone excess. For this reason, the new WHO classification endorses the nomenclature of the HISTALDO classification which uses CYP11B2 immunohistochemistry to identify functional sites of aldosterone production to help predict the risk of bilateral disease in primary aldosteronism. Adrenal cortical carcinomas are subtyped based on their morphological features to include conventional, oncocytic, myxoid, and sarcomatoid subtypes. Although the classic histopathologic criteria for diagnosing adrenal cortical carcinomas have not changed, the 2022 WHO classification underscores the diagnostic and prognostic impact of angioinvasion (vascular invasion) in these tumors. Microscopic angioinvasion is defined as tumor cells invading through a vessel wall and forming a thrombus/fibrin-tumor complex or intravascular tumor cells admixed with platelet thrombus/fibrin. In addition to well-established Weiss and modified Weiss scoring systems, the new WHO classification also expands on the use of other multiparameter diagnostic algorithms (reticulin algorithm, Lin-Weiss-Bisceglia system, and Helsinki scoring system) to assist the workup of adrenal cortical neoplasms in adults. Accordingly, conventional carcinomas can be assessed using all multiparameter diagnostic schemes, whereas oncocytic neoplasms can be assessed using the Lin-Weiss-Bisceglia system, reticulin algorithm and Helsinki scoring system. Pediatric adrenal cortical neoplasms are assessed using the Wieneke system. Most adult adrenal cortical carcinomas show > 5 mitoses per 10 mm2 and > 5% Ki67. The 2022 WHO classification places an emphasis on an accurate assessment of tumor proliferation rate using both the mitotic count (mitoses per 10 mm2) and Ki67 labeling index which play an essential role in the dynamic risk stratification of affected patients. Low grade carcinomas have mitotic rate of ≤ 20 mitoses per 10 mm2, whereas high-grade carcinomas show > 20 mitoses per 10 mm2. Ki67-based tumor grading has not been endorsed in the new WHO classification, since the proliferation indices are continuous variables rather than being static thresholds in tumor biology. This new WHO classification emphasizes the role of diagnostic and predictive biomarkers in the workup of adrenal cortical neoplasms. Confirmation of the adrenal cortical origin of a tumor remains a critical requirement when dealing with non-functional lesions in the adrenal gland which may be mistaken for a primary adrenal cortical neoplasm. While SF1 is the most reliable biomarker in the confirmation of adrenal cortical origin, paranuclear IGF2 expression is a useful biomarker in the distinction of malignancy in adrenal cortical neoplasms. In addition to adrenal myelolipoma, the new classification of adrenal cortical tumors has introduced new sections including adrenal ectopia, based on the potential role of such ectopic tissue as a possible source of neoplastic proliferations as well as a potential mimicker of metastatic disease. Adrenal cysts are also discussed in the new classification as they may simulate primary cystic adrenal neoplasms or even adrenal cortical carcinomas in the setting of an adrenal pseudocyst.

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

Abstract
Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders affecting cortisol biosynthesis. Reduced activity of an enzyme required for cortisol production leads to chronic overstimulation of the adrenal cortex and accumulation of precursors proximal to the blocked enzymatic step. The most common form of CAH is caused by steroid 21-hydroxylase deficiency due to mutations in CYP21A2. Since the last publication summarizing CAH in Endocrine Reviews in 2000, there have been numerous new developments. These include more detailed understanding of steroidogenic pathways, refinements in neonatal screening, improved diagnostic measurements utilizing chromatography and mass spectrometry coupled with steroid profiling, and improved genotyping methods. Clinical trials of alternative medications and modes of delivery have been recently completed or are under way. Genetic and cell-based treatments are being explored. A large body of data concerning long-term outcomes in patients affected by CAH, including psychosexual well-being, has been enhanced by the establishment of disease registries. This review provides the reader with current insights in CAH with special attention to these new developments.

Abstract
BACKGROUND Undiagnosed congenital adrenal hyperplasia (CAH) can cause adrenal incidentalomas, but the frequency is unclear. OBJECTIVES This study aimed to investigate the prevalence of CAH in a population with adrenal incidentalomas and report the clinical characterization. MATERIAL AND METHODS This was a prospective study performed at a regional hospital from 2016 to 2021. Patients with adrenal incidentalomas were investigated with an adrenocorticotropic hormone (ACTH)-stimulation test in addition to hormonal workup. Serum cortisol and 17-hydroxyprogesterone (17OHP) were analyzed. Individuals with a basal or stimulated 17OHP ≥30 nmol/L were classified as suspicious non-classic CAH, and a CYP21A2-gene analysis was performed in these subjects. RESULTS In total, 320 individuals with adrenal incidentalomas were referred to the center, and of these individuals, an ACTH-stimulation test was performed in 222 (median age, 67 (24-87) years; 58.6% women; and 11.7% with bilateral lesions). None of the individuals presented a basal 17OHP ≥30 nmol/L, but there were 8 (3.6%) who did after ACTH stimulation. Four of these subjects (50%) presented bilateral lesions, and the tumor size was larger compared to that of the individuals with a stimulated 17OHP <30 nmol/L (median, 38 (19-66) vs. 19 (11-85) mm, p=0.001). A CYP21A2 variation (p.Val282Leu) was detected in one of the eight subjects with a stimulated 17OHP ≥30 nmol/L, i.e., the patient was a heterozygotic carrier. None of the eight subjects presented with cortisol insufficiency or clinical signs of hyperandrogenism. CONCLUSIONS The prevalence of non-classic CAH in an adrenal incidentaloma cohort was 3.6% based on stimulated 17OHP and 0% based on gene analysis. CAH should be considered in AI management in selected cases and confirmed by genetic analysis.

Abstract
Adrenal myelolipomas are benign, lipomatous tumours with elements of myeloid cells, most of which present as adrenal incidentalomas and comprise 3·3-6·5% of all adrenal masses. Adrenal myelolipomas are usually unilateral (in 95% of cases), variable in size, most often found during midlife, and affect both sexes almost equally. On imaging, adrenal myelolipomas show pathognomonic imaging features consistent with the presence of macroscopic fat. Large adrenal myelolipomas can cause symptoms of mass effect, and can occasionally be complicated by haemorrhage. In the event of a concomitant adrenal cortical adenoma or hyperplasia, adrenal hormone excess might be detected in patients with adrenal myelolipoma. Patients with congenital adrenal hyperplasia exhibit a higher prevalence of adrenal myelolipomas than other patient groups, and are at risk of developing large and bilateral lesions. This Review discusses the pathogenesis, clinical presentation, and management of adrenal myelolipomas.

Abstract
INTRODUCTION Heterozygotes (HZs) for 21-hydroxylase deficiency (21OHD) are highly prevalent, ranging from 1:60 to 1:11 for classic and nonclassic (NC) forms, respectively. Detection of HZ and asymptomatic NC by CYP21A2 genotyping is valuable for genetic counselling, but costly, complex and narrowly available. Adrenocorticotropic hormone (ACTH)-stimulated serum 17-hydroxyprogesterone (17P) and 21-deoxycortisol (21DF) discriminate 21OHD phenotypes effectively, notably if measured simultaneously by liquid chromatography-tandem mass spectrometry (LC-MS/MS). OBJECTIVE This study was performed to reassess former LC-MS/MS-defined post-ACTH 21DF, 17P and cortisol (F) cutoffs in family members at risk for 21OHD. DESIGN AND PATIENTS Prospective study in which we screened 58 asymptomatic relatives from families with 21OHD patients and compared post-ACTH steroid phenotypes with subsequent genotypes. RESULTS Post-ACTH 21DF, 17P, F and (21DF + 17P)/F ratio segregate NC, HZ and wild-type (WT) phenotypes (subsequently genotyped) with some overlap. New receiver operating characteristic curve-defined cutoffs for post-ACTH 21DF, 17P and (21DF + 17P)/F ratio are 60 ng/dl, 310 ng/dl and 12 (unitless). Twenty-six of 33 HZ and all 6 NC (82.1%) had post-ACTH 21DF > 60 and 17P > 310 ng/dl, whereas 17/19 WT (89.5%) had values below cutoffs. Post-ACTH 21DF and 17P had a strong positive correlation (r = .9558; p < .001). A (21DF + 17P)/F ratio > 12 correctly identified 36 of 39 HZ plus NC (92.3% sensitivity) with 84.2% specificity (16 of 19 WT). Given the high frequency of 21OHD HZ, the negative prediction of ratio values below 12 excludes heterozygosity in 99.8% and 99.1% for classic and NC mutations, respectively. CONCLUSIONS Reassessed ACTH-stimulated 21DF and 17P cutoffs by LC-MS/MS (60 and 310 ng/dl, respectively) correctly recognised 82.5% HZ plus NC, but combined precursor-to-product ratio ([21DF + 17P]/F) cutoff of 12 was superior, identifying 92.3% HZ plus NC. Since one WT subject is an outlier (potential HZ), these values would be somewhat better reinforcing their utility for screening asymptomatic relatives at risk for 21OHD.

Abstract
BACKGROUND 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder with an incidence of 1:10,000-1:20,000 and is the result of various mutations in the CYP21A2 gene. 21OHD has been described in many different populations, but it has not been studied in Roma individuals so far. The aim of the study was to analyse the genotype in Roma patients with 21OHD and the prevalence of the disease in the Roma population of North Macedonia. METHODS Molecular analysis of the nine most frequent CYP21A2 mutations in all known Roma patients with CAH in North Macedonia, relatives and healthy individuals of Roma ancestry, using the PCR/ACRS method. RESULTS Ten Roma patients with 21OHD were identified, of which nine had the salt-wasting and one had the simple virilizing form. Calculated incidence of 21OHD in the North Macedonian Roma population was 1:3375. Interestingly, 9/10 patients (90%) were homozygous for the In2G splicing mutation (293-13A/C > G). Standard therapy with hydrocortisone and fludrocortisone had been introduced according to the guidelines. In 16 healthy relatives investigated for CYP21A2 mutations, heterozygosity for the In2G mutation was detected in 13/32 (40.6%) alleles. In 100 healthy Roma individuals, none related to the analysed families, no CYP21A2 mutations were detected. CONCLUSION The Roma population in North Macedonia had a very high incidence of classic 21OHD. Almost all patients had the severe salt-wasting form and the In2G/In2G genotype.

Abstract
Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a complicated condition genetically, clinically, and treatment wise. Genetically, there are numerus mutations with different effect on enzyme activity that make genetic diagnosis a challenge. Clinically, there are a wide range of presentations from asymptomatic patients to the severe life-threatening classic CAH. Both an asymptomatic heterozygote and a mildly affected non-classical patient can carry a 'severe' mutation and endow it to their offspring. We present a case of non-classic CAH and discuss the problematic relations between biochemical and genetic diagnosis. By integrating the seemingly contradicting literature, we provide a new simple tool to assess the risk of such patients to give birth to a child with classic CAH.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder of adrenal steroidogenesis with a broad spectrum of clinical presentations, ranging from the severe classical salt-wasting (SW) and simple-virilizing (SV) form, to the mild nonclassical form. A large variety of CYP21A2 genotypes in correlation with phenotype have been described. MATERIALS AND METHODS DNA samples from a 14-day-old male newborn with clinical and laboratory signs of SW CAH and family members were subjected for molecular analysis of the nine most common point CYP21A2 mutations by ACRS/PCR method. Direct DNA sequencing of the whole CYP21A2 gene was performed to detect the second mutant allele in the patient. The in silico predicting analysis and the crystal structure analysis of the mutated CYP21A2 protein have been performed. RESULTS Molecular analysis confirmed that the patient was compound heterozygote carrying p.Q318X mutation inherited from the mother and a novel c.1271_1279delGTGCCCGCG (p.G424_R426del) variant in exon 10 inherited from the father. The in silico predicting software tools classified the novel mutation as pathogenic. Crystal structure analysis showed that the three residues affected by the novel in-frame deletion form several hydrogen bonds that could lead to impaired stability and function of the CYP21A2 protein. These findings were concordant with the patient's phenotype. The need of several molecular methods to elucidate the genotype in this patient has also been discussed. CONCLUSIONS A novel 9 bp deletion in CYP21A2 gene with predicted pathogenic effect on the enzyme activity was detected in neonatal patient causing severe SW 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
PURPOSE OF REVIEW The introduction of synthetic glucocorticoids 70 years ago made survival possible in classic 21-hydroxylase deficiency (21OHD). The currently used glucocorticoid therapy may lead to unphysiological dosing with negative consequencies on health in addition to the problems that may arise due to androgen over-exposure. RECENT FINDINGS Fertility in females with 21OHD seemed to be impaired, especially in the salt-wasting (SW) phenotype but when pregnancies did occur there was a higher risk for gestational diabetes and cesearean section. Increased fat mass, body mass index, insulin resistance and frequency of autoimmune disorders as well as impaired echocardiographic parameters and lower bone mineral density were found in 21OHD compared to controls. Negative effects on cognitive functions have been identified. Adrenal tumors, especially myelolipomas, were prevalent. Increased knowledge on steroid metabolism in 21OHD and urine steroid profiling may improve assessment of treatment efficacy. Nevanimibe, abiraterone acetate and anastrozole may have a place in the future management of 21OHD. Long-acting glucocorticoids may be a less favorable, especially dexamethasone. SUMMARY The various clinical outcomes need regular monitoring. Negative consequencies are to large extent the result of the unphysiological glucocorticoid replacement. Modern management with improved follow-up and future addition of new drugs may improve outcomes.

Abstract
BACKGROUND AND OBJECTIVE Congenital adrenal hyperplasia involves a series of autosomal recessive disorders where adrenal steroidogenesis is affected. We present a detailed molecular investigation of 13 newborns affected from the severe form of congenital adrenal hyperplasia related to 21-hydroxylase deficiency. METHODS All patients were diagnosed with classical congenital adrenal hyperplasia in the neonatal period due to adrenal crisis and/or ambiguous genitalia presentation. None of the infants was identified through a congenital adrenal hyperplasia newborn screening program. A molecular analysis of the CYP21A2 gene and a familiar segregation analysis were performed. RESULTS Adrenal crisis was the most severe manifestation in the male salt-wasting newborns while all female patients presented with atypical genitalia. Newborns were correctly genotyped and no genotype-phenotype divergences were found. Two novel severe genotypes, not previously reported, were identified. The novel CYP21A2 frameshift mutations (c.793delG and c.297dupG) were added to the other 45 variants recently reported in the literature, leading to a total count of 279 pathogenic variants affecting the gene. CONCLUSIONS We have successfully genotyped 13 infants diagnosed with classical congenital adrenal hyperplasia after birth. Our molecular approach led to the identification of two novel frameshift CYP21A2 pathogenic variants related to the salt-wasting form of congenital adrenal hyperplasia.

Abstract
Steroid 21-hydroxylase deficiency accounts for 95% of congenital adrenal hyperplasia (CAH) cases. Newborn screening has allowed for early detection of the disease, and currently, molecular analysis can identify the genotypes of these patients. Phenotype-genotype correlation has been well described in previous studies. In Costa Rica, there is no data about the genetic background of these patients, nor their phenotypic correlation. Design Observational, retrospective, descriptive study based on the review of patient records who had a diagnosis of CAH and were performed molecular analysis using gene sequencing or MLPA during the period from 2006 to 2018 (N = 58). Objective To describe the clinical and genetic characteristics of CAH patients due to 21-hydroxylase deficiency at the National Children's Hospital “Dr. Carlos Sáenz Herrera”, Caja Costarricense de Seguro Social (CCSS) in Costa Rica. Results 53% (31/58) of the patients were male and 80% (37/46) were born full term; 72% (42/58) had salt wasting phenotype, 9% (5/58) simple virilizing phenotype and 19% (11/58) non-classic phenotype. The most frequent variants were c.292+5G>A in 26% (15/58) of patients and Del/Del in 21% (12/58) of them. Conclusions The most frequent mutation in our study population was the c.292+5G>A, which was found in 15/58 patients. This rare variant has only been reported in three other studies so far but as an infrequent mutation in CAH patients. The genetic characteristics of Costa Rican patients differ from what has been documented worldwide and could respond to a founder effect.

Abstract
BACKGROUND There are several studies that show a good genotype-phenotype correlation in congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD). However, there is well-documented evidence of inconsistency in some cases. OBJECTIVES To determine if there is a correlation between the identified mutations and the clinical manifestations of 21OHD in the Cuban population. METHODS A cross-sectional descriptive study of all patients referred for a molecular diagnosis of 21OHD in Cuba from January 2000 to December 2018. The clinical manifestations of each patient were identified and classified according to the phenotype. The CYP21A2 gene was analyzed for the presence of 5 point mutations involved in the pathogenesis of 21OHD (intron 2, deletion of 8bp, I172N, P30L, and Q318X); correlation was sought between the phenotypic characteristics and the frequencies of point mutations in the patients using the Spearman test. RESULTS A total of 55 patients underwent direct analysis of the CYP21A2 gene in order to determine the presence of the 5 point mutations. Point mutations were identified in 31 patients, which corresponded to 56%. A statistically significant genotype-phenotype correlation was found. CONCLUSIONS The correlation between the detected molecular defect and the clinical expression of 21OHD was reasonable in the Cuban population, which could allow phenotypic predictions to be made from the genotype.

Abstract
Substantial research has been performed during the last decades on the clinical and genetic variability of congenital adrenal hyperplasia (CAH) and its most common form, 21-hydroxylase deficiency (21OHD). CAH is one of the most prevalent autosomal recessive diseases in humans, and it can be divided into classic-further subdivided into salt wasting (SW) and simple virilizing (SV)-and non-classic (NC) forms. Pathogenic variants of CYP21A2 gene, encoding the 21-hydroxylase enzyme, have been reported with variable prevalence in different populations. NM_000500.9:c.293-13C/A>G (In2G) variant represents the most common CYP21A2 gene changes related to the classic 21OHD form. However, the phenotype of In2G carriers is variable depending on the variant homozygous/heterozygous status and combination with other CYP21A2 pathogenic variants. In addition, identical genotypes, harboring the homozygous In2G variant, can present with variable phenotypes including the SW and SV or rarely NC form of the disease. Here, we analyze and present the clinical aspects, genotype/phenotype correlations, and other characteristics related to the CYP21A2 In2G variant.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) is an autosomal recessive group of diseases. 21-Hydroxylase deficiency (21OHD) accounts for between 95 and 99% of all CAH cases. OBJECTIVES To characterize the genotype of patients clinically diagnosed with 21OHD and to identify the most frequent mutations in the Cuban population. METHODS Cross-sectional descriptive study that included all patients diagnosed with 21OHD from January 2000 to December 2018. For the molecular analysis of the CYP21A2 gene, a protocol was used that used the polymerase chain reaction in 2 stages; in the first stage genomic DNA was amplified and 5 point mutations were detected in the second stage (Intron 2, Deletion of 8 bp, G318X, I172N and P30L). RESULTS The 5 point mutations were identified in 31 of the 55 (56%) studied patients, 16/21 (76%) in the salt-wasting, 12/18 (67%) in the simple virilizing and 3/16 (19%) in the nonclassical form. The Intron 2 mutation was the most frequent, followed by G318X and 8 bp deletion. Compound heterozygotes were found in 10 patients, all corresponded to classic forms of the disease. CONCLUSIONS The causal CYP21A2 gene mutation was detected in 56% (72% in classic CAH), which makes the method encouraging. The most frequent mutations observed were Intron 2 and G318X. The detection of mutations offers confirmation of diagnosis, prediction of phenotype and genetic counseling.

Abstract
OBJECTIVE The prevalence of adrenal tumors in congenital adrenal hyperplasia (CAH) is uncertain. Our objective was to estimate the prevalence and characteristics of adrenal tumors and myelolipoma in CAH, and investigate clinical features of this population. METHODS We carried out systematic searches in Medline Ovid and Embase for articles published until January, 2020. Studies with confirmed CAH, biochemically and/or genetically, were included. The two authors independently extracted data from each study. RESULTS Six cohort studies were included in the prevalence calculation. In addition, 32 case reports on adrenal myelolipomas and CAH were included. The prevalence of adrenal tumors in CAH was 29.3%. When only studies with genetically verified cytochrome P450, Family 21, subfamily A, polypeptide 2 gene (CYP21A2) mutations were included the prevalence was 23.6%. The prevalence of myelolipoma in CAH was 7.4% (verified CYP21A2 mutations 8.6%). The proportion of myelolipoma in the adrenal tumors was 25.4% (genetically verified 36.6%). The median (range) age at tumor diagnosis was 36.0 (12 to 60) years and there were more tumors in males than in females (37.9% versus 22.1%; P<.05). In patients with myelolipomas, 93.5% had an undiagnosed or poorly managed CAH. CONCLUSION Patients with CAH had a high prevalence of adrenal tumors, particularly myelolipomas. Those with myelolipomas had a high frequency of late-diagnosed or poorly controlled CAH. Adrenal imaging may be considered in patients with CAH, especially if abdominal pain is present.

Abstract
Newborn screening for 21-hydroxylase deficiency (21OHD), the most common form of congenital adrenal hyperplasia, has been performed routinely in the United States and other countries for over 20 years. Screening provides the opportunity for early detection and treatment of patients with 21OHD, preventing salt-wasting crisis during the first weeks of life. However, current first-tier screening methodologies lack specificity, leading to a large number of false positive cases, and adequate sensitivity to detect all cases of classic 21OHD that would benefit from treatment. This review summarizes the pathology of 21OHD and also the key stages of fetal hypothalamic-pituitary-adrenal axis development and adrenal steroidogenesis that contribute to limitations in screening accuracy. Factors leading to both false positive and false negative results are highlighted, along with specimen collection best practices used by laboratories in the United States and worldwide. This comprehensive review provides context and insight into the limitations of newborn screening for 21OHD for laboratorians, primary care physicians, and endocrinologists.

Abstract
Congenital adrenal hyperplasia (CAH) was the fourth disorder added to the national Swedish neonatal screening program in 1986, and approximately 115,000 newborns are screened annually. Dried blood spot (DBS) screening with measurement of 17-hydroxyprogesterone (17OHP) is also offered to older children moving to Sweden from countries lacking a national DBS screening program. Here, we report an update on the CAH screening from January 2011 until December 2019. Results: During the study period, 1,030,409 newborns and 34,713 older children were screened. In total, 87 newborns were verified to have CAH, which gives an overall positive predictive value (PPV) of 11% and 21% for term infants. Including the five missed CAH cases identified during this period, this gives an incidence of 1:11,200 of CAH in Sweden. Among the older children, 12 of 14 recalled cases were found to be true positive for CAH. All patients were genotyped as part of the clinical follow-up and 70% of the newborns had salt wasting (SW) CAH and 92% had classic CAH (i.e., SW and simple virilizing (SV) CAH). In the group of 12 older children, none had SW CAH and two had SV CAH. Conclusion: The incidence of classic CAH is relatively high in Sweden. Early genetic confirmation with CYP21A2 genotyping has been a valuable complement to the analysis of 17OHP to predict disease severity, make treatment decisions and for the follow-up and evaluation of the screening program.

Abstract
Despite numerous studies in the field of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, some clinical variability of the presentation and discrepancies in the genotype/phenotype correlation are still unexplained. Some, but not all, discordant phenotypes caused by mutations with known enzyme activity have been explained by in silico structural changes in the 21-hydroxylase protein. The incidence of P30L mutation varies in different populations and is most frequently found in several Central and Southeast European countries as well as Mexico. Patients carrying P30L mutation present predominantly as non-classical CAH; however, simple virilizing forms are found in up to 50% of patients. Taking into consideration the residual 21-hydroxulase activity present with P30L mutation this is unexpected. Different mechanisms for increased androgenization in patients carrying P30L mutation have been proposed including influence of different residues, accompanying promotor allele variability or mutations, and individual androgene sensitivity. Early diagnosis of patients who would present with SV is important in order to improve outcome. Outcome studies of CAH have confirmed the uniqueness of this mutation such as difficulties in phenotype classification, different fertility, growth, and psychologic issues in comparison with other genotypes. Additional studies of P30L mutation are warranted.

Abstract
PURPOSE Newborn screening laboratories are challenged to develop reporting algorithms that accurately identify babies at increased risk for congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD). Screening algorithms typically use cutoff values for a key steroid(s) and include considerations for covariates, such as gestational age or birth weight, but false-positive and false-negative results are still too frequent, preventing accurate assessments. Principal component analysis (PCA) is a statistical method that reduces high-dimensional data to a small number of components, capturing patterns of association that may be relevant to the outcome of interest. To our knowledge, PCA has not been evaluated in the newborn screening setting to determine whether it can improve the positive predictive value of 21OHD screening. METHODS PCA was applied to a data set of 920 newborns with measured concentrations of 5 key steroids that are known to be perturbed in patients with 21OHD. A decision tree for the known outcomes (confirmed 21OHD cases and unaffected individuals) was created with 2 principal components as predictors. The effectiveness of the PCA-derived decision tree was compared with the current algorithm. RESULTS PCA improved the positive predictive value of 21OHD screening from 20.0% to 66.7% in a retrospective study comparing the current algorithm to a tree-based algorithm using PCA-derived variables. The streamlined PCA-derived decision tree, comprising only 3 assessment points, greatly simplified the 21OHD reporting algorithm. CONCLUSIONS This first report of PCA applied to newborn screening for 21OHD demonstrates enhanced detection of affected individuals within the unaffected population.

Abstract
Molecular genetic testing for congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is offered worldwide and is of importance for differential diagnosis, carrier detection and adequate genetic counseling, particularly for family planning. In 2008 the European Molecular Genetics Quality Network (EMQN) for the first time offered a European-wide external quality assessment scheme for CAH (due to 21-OH deficiency). The interest was great and over the last years at about 60 laboratories from Europe, USA and Australia regularly participated in that scheme. These best practice guidelines were drafted on the basis of the extensive knowledge and experience got from those annually organized CAH-schemes. In order to obtain the widest possible consultation with practicing laboratories the draft was therefore circulated twice by EMQN to all laboratories participating in the EQA-scheme for CAH genotyping and was updated by that input. The present guidelines address quality requirements for diagnostic molecular genetic laboratories, as well as criteria for CYP21A2 genotyping (including carrier-testing and prenatal diagnosis). A key aspect of that article is the use of appropriate methodologies (e.g., sequencing methods, MLPA (multiplex ligation dependent probe amplification), mutation specific assays) and respective limitations and analytical accuracy. Moreover, these guidelines focus on classification of variants, and the interpretation and standardization of the reporting of CYP21A2 genotyping results. In addition, the article provides a comprehensive list of common as well as so far unreported CYP21A2-variants.

Abstract
CONTEXT Patients with classic congenital adrenal hyperplasia (CAH) are treated postnatally with lifelong glucocorticoid (GC) replacement therapy. Previous results on general cognitive ability in individuals with CAH have been conflicting. OBJECTIVE To evaluate long-term cognitive effects of GC replacement therapy and the impact of early diagnosis in children with CAH. DESIGN AND SETTING Observational study with patients from a single research institute. PATIENTS 32 children with CAH (mean age 11.5 years) identified through the Swedish national neonatal screening program for CAH and 52 matched population controls (mean age 10.7 years). Eleven (6 female) children with CAH who were treated prenatally with dexamethasone (DEX), (CAH-DEX) (mean age 11.7 years). INTERVENTION GC replacement therapy, neonatal screening for CAH. MEASURES Cognitive abilities assessed with standardized neuropsychological tests (Wechsler scales, Span Board Test, Stroop Interference Test, NEPSY list learning). RESULTS Children with CAH (not prenatally treated) performed equally well as population controls on a series of tests assessing general intellectual ability and executive functions. No significant differences were observed in cognitive performance between patients with different genotypes (null, non-null). Patients with salt-wasting CAH performed poorer than patients with simple virilizing CAH in a test assessing visuo-spatial working memory (P = 0.039), although the performance was within the normal range for the population. Prenatally DEX-treated girls with CAH had lower verbal intellectual ability compared with CAH girls not exposed to prenatal treatment (P = 0.037). CONCLUSION Children and adolescents with CAH who were diagnosed early via a neonatal screening program and treated with hydrocortisone had normal psychometric intelligence and executive functions.

Abstract
Considerable researches on sex steroids and insulin action have suggested a mutual interaction between hyperandrogenemia and insulin resistance (IR). The objective of present study was to evaluate the androgens levels in young females with emphasis on the association of 17OHP with IR. Serum concentrations of glucose, insulin, and androgens in 80 young females were measured by standard routine procedures. Total testosterone (TT), dihydrotestosterone (DHT), dehydroepiandrosterone sulfate (DHEAS), androstenedione (ASD), and 17-hydroxyprogesterone (17OHP) levels were higher in patients with IR compared to healthy controls (p < .05). 17OHP was associated with IR and other androgens tested in young females. According to the results, androgen excess was associated with IR in young females and TT appeared to be independent predictor of IR in these patients. These data may suggest that simultaneous quantification of an androgen profile including at least TT, DHT, and 17OHP can present useful clinical information for assessment of androgen excess.

Abstract
CONTEXT Congenital adrenal hyperplasia (CAH) is a common monogenic recessive disorder. It has been suggested that CYP21A2 deficiency is common because carriers may have a survival advantage, 1 in 15,000 in most populations. Carriers of CYP21A2 mutations typically do not have clinical symptoms but have a defined phenotype with a more prompt cortisol response to ACTH. OBJECTIVE We investigated whether the mortality was lower, and determined the cause of death in carriers and population controls. DESIGN A total of 1143 obligate carriers of a CYP21A2 mutation (561 men) were identified from the Swedish National CAH Registry, encompassing >700 patients and the Multi-Generation Registry to identify their parents. The mortality and cause of death were identified through the Swedish Cause of Death Registry. The hazard ratios (HRs) and 95% CIs were calculated. The results were compared with controls from the general population, matched for sex and age. RESULTS The overall mortality was lower in carriers of a CYP21A2 mutation compared with the controls (HR 0.79; 95% CI, 0.678 to 0.917; P = 0.002). The difference was more marked among carriers of a more severe mutation. Infection as the cause of death was significantly lower (HR 0.65; 95% CI, 0.48 to 0.87; P < 0.01), particularly for death in pneumonia (HR 0.22; 95% CI, 0.06 to 0.88; P = 0.03). The lower overall mortality among women compared with men in the general population was confirmed among both carriers and controls. CONCLUSION Obligate CYP21A2 carriers of a classic mutation had a reduced mortality. Specifically, a possible reduced mortality due to pneumonia was seen.

Wisconsin's Screening Algorithm for the Identification of Newborns with Congenital Adrenal Hyperplasia. Int J Neonatal Screen 2019; 5:33.

Abstract
Newborn screening for congenital adrenal hyperplasia (CAH) has one of the highest false positive rates of any of the diseases on the Wisconsin panel. This is largely due to the first-tier immune assay cross-reactivity and physiological changes in the concentration of 17-hydroxyprogesterone during the first few days of life. To improve screening for CAH, Wisconsin developed a second-tier assay to quantify four different steroids (17-hydroxyprogesterone, 21-deoxycortisol, androstenedione, and cortisol) by liquid chromatography-tandem mass spectrometry (LC-MSMS) in dried blood spots. From validation studies which included the testing of confirmed CAH patients, Wisconsin established its own reporting algorithm that incorporates steroid concentrations as well as two different ratios-the birth weight and the collection time-to identify babies at risk for CAH. Using the newly developed method and algorithm, the false positive rate for the CAH screening was reduced by 95%. Patients with both classical forms of CAH, salt-wasting and simple virilizing, were identified. This study replicates and expands upon previous work to develop a second-tier LC-MSMS steroid profiling screening assay for CAH. The validation and prospective study results provide evidence for an extensive reporting algorithm that incorporates multiple steroids, birth weight, and collection times.

Abstract
OBJECTIVE To describe the results obtained in a neonatal screening program after its implementation and to assess the clinical and molecular profiles of confirmed and suspicious congenital adrenal hyperplasia cases. METHODS A cross-sectional study was conducted. Newborns with suspected disease due to high 17-hydroxyprogesterone levels and adjusted for birth weight were selected. Classical congenital adrenal hyperplasia (salt-wasting and simple virilizing forms) was diagnosed by an increase in 17-hydroxyprogesterone levels as confirmed in the retest, clinical evaluation, and genotype determined by SNaPshot and multiplex ligation-dependent probe amplification. RESULTS After 24 months, 15 classic congenital adrenal hyperplasia cases were diagnosed in a total of 217,965 newborns, with an estimated incidence of 1:14,531. From 132 patients, seven non-classical and 14 heterozygous patients were screened for CYP21A2 mutations, and 96 patients presented false positives with wild type CYP21A2. On retest, increased 17-hydroxyprogesterone levels were found in classical congenital adrenal hyperplasia patients and showed significant correlation with genotype-related classical genital adrenal hyperplasia. The most frequent mutations were IVS2-13A/C>G followed by gene deletion or rearrangement events in the classical form. In non-classical and heterozygous diseases, p.Val282Leu was the most common mutation. CONCLUSIONS The results underscore the effectiveness of congenital adrenal hyperplasia neonatal screening in the public health system and indicate that the adopted strategy was appropriate. The second sample collection along with genotyping of suspected cases helped to properly diagnose both severe and milder cases and delineate them from false positive patients.

Abstract
Management of congenital adrenal hyperplasia (CAH) requires both glucocorticoid replacement and suppression of adrenal androgen synthesis. It is recommended that children with CAH be treated with hydrocortisone, but the appropriate glucocorticoid regimen in adults is uncertain. In order to review the outcomes of different glucocorticoid regimens in the management of CAH, a systematic search of PubMed/MEDLINE and Web of Science was conducted, including reports published up to 25 February 2019. Studies that compared at least two types of glucocorticoid preparation were included. The following information was extracted from each study: first author, year of publication, number and characteristics of patients and control subjects, types and doses of glucocorticoid regimen used, study design and outcomes [e.g., biochemical tests, weight, height, body mass index (BMI), bone mineral density (BMD)]. A total of 23 studies were included in the qualitative synthesis, with 19 included in the quantitative synthesis. Dexamethasone was associated with the greatest degree of adrenal suppression; there was no significant difference in 17-hydroxyprogesterone (17OHP) and androstenedione levels between patients treated with hydrocortisone or prednisolone. Patients treated with dexamethasone had the lowest BMD and the highest BMI. Although dexamethasone therapy is associated with significantly lower 17OHP and androstenedione levels, it is also associated with more adverse effects. There do not appear to be significant differences between hydrocortisone and prednisolone therapy, and the choice of agent should be based on individual patient factors.

Abstract
Context The prevalence of autoimmune disorders in individuals with 21-hydroxylase deficiency (21OHD) is unclear. The gene responsible, CYP21A2, is located in a highly immunologically active region. Objective To study the prevalence of autoimmune disorders in individuals with 21OHD. Design, Setting, and Participants Patients with 21OHD (n = 714) were compared with controls matched for sex, year, and place of birth (n = 71,400). Data were derived by linking National Population-Based Registers. Subgroup analyses were performed regarding phenotype and CYP21A2 genotype. Main Outcome Measures Number and type of autoimmune disorders. Results Mean age (± SD) was 29.8 ± 18.4 years. Individuals with 21OHD had more autoimmune disorders than did controls [7.4% vs 5.1%, P < 0.01; relative risk (RR) 1.47 (95% CI, 1.13 to 1.91)], especially male patients [6.8% vs 4.1%, P < 0.05; RR, 1.64 (95% CI, 1.08 to 2.49)], whereas it did not reach significance for female patients [7.9% vs 5.8%, P = 0.068; RR, 1.37 (95% CI, 0.98 to 1.92)]. Among the specific autoimmune groups and disorders, autoimmune endocrine disorders and autoimmune thyroid disorders, including Graves disease, were significantly increased in the entire cohort of patients and for male and female patients separately. Inflammatory bowel disease (IBD) and systemic connective tissue disorders did not reach significant levels for the entire cohort (P = 0.075 and 0.05, respectively), but male patients were more affected by IBD (P = 0.022). The groups with milder phenotypes and genotypes seemed to be more affected by autoimmune disorders. Conclusions 21OHD was associated with an increased prevalence of autoimmune disorders. The relatively young age of the patient cohort and possible protective effects by glucocorticoid treatment may have underestimated the risk.

Abstract
PURPOSE 3β-hydroxysteroid dehydrogenase type 2 deficiency (3βHSD2D) is a very rare variant of congenital adrenal hyperplasia (CAH) causing less than 0.5% of all CAH. The aim was to review the literature. METHODS PubMed was searched for relevant articles. RESULTS 3βHSD2D is caused by HSD3B2 gene mutations and characterized by impaired steroid synthesis in the gonads and the adrenal glands and subsequent increased dehydroepiandrosterone (DHEA) concentrations. The main hormonal changes observed in patients with 3βHSD2D are elevated ratios of the Δ5-steroids over Δ4-steroids but molecular genetic testing is recommended to confirm the diagnosis. Several deleterious mutations in the HSD3B2 gene have been associated with salt-wasting (SW) crisis in the neonatal period, while missense mutations have been associated with a non-SW phenotype. Boys may have ambiguous genitalia, whereas girls present with mild or no virilization at birth. The existence of non-classic 3βHSD2D is controversial. In an acute SW crisis, the treatment includes prompt rehydration, correction of hypoglycemia, and parenteral hydrocortisone. Similar to other forms of CAH, glucocorticoid and mineralocorticoid replacement is needed for long-term management. In addition, sex hormone replacement therapy may be required if normal progress through puberty is failing. Little is known regarding possible negative long-term consequences of 3βHSD2D and its treatments, e.g., fertility, final height, osteoporosis and fractures, adrenal and testicular tumor risk, and mortality. CONCLUSION Knowledge is mainly based on case reports but many long-term outcomes could be presumed to be similar to other types of CAH, mainly 21-hydroxylase deficiency, although in 3βHSD2D it seems to be more difficult to suppress the androgens.

Abstract
OBJECTIVE The purpose of this narrative review was to summarize available data on testosterone levels in normal, healthy adult males and females, to provide a physiologic reference framework to evaluate testosterone levels reported in males and females with conditions that elevate androgens, such as disorders of sex development (DSD), and to determine the separation or overlap of testosterone levels between normal and affected males and females. METHODS A literature review was conducted for published papers, from peer reviewed journals, reporting testosterone levels in healthy males and females, males with 46XY DSD, and females with hyperandrogenism due to polycystic ovary syndrome (PCOS). Papers were selected that had adequate characterization of participants, and description of the methodology for measurement of serum testosterone and reporting of results. RESULTS In the healthy, normal males and females, there was a clear bimodal distribution of testosterone levels, with the lower end of the male range being four- to fivefold higher than the upper end of the female range(males 8.8-30.9 nmol/L, females 0.4-2.0 nmol/L). Individuals with 46XY DSD, specifically those with 5-alpha reductase deficiency, type 2 and androgen insensitivity syndrome testosterone levels that were within normal male range. Females with PCOS or congenital adrenal hyperplasia were above the normal female range but still below the normal male range. CONCLUSIONS Existing studies strongly support a bimodal distribution of serum testosterone levels in females compared to males. These data should be considered in the discussion of female competition eligibility in individuals with possible DSD or hyperandrogenism.

Abstract
Prenatal treatment of congenital adrenal hyperplasia with dexamethasone (DEX) has been in use since the mid-1980s and has proven effective at reducing virilization of external genitalia in affected girls. However, multiple experimental studies on animals and clinical studies on humans show that prenatal administration of glucocorticoids may cause unwanted adverse effects which have raised concerns about the long-term safety of the treatment. The long-term outcome of prenatal DEX treatment on cognition has been investigated, but the results are still conflicting. Overall, most of the evidence points towards a negative effect on executive functions where girls seem to be more susceptible than boys. Some effects on social behavior have been observed, but results are still contradictory and treated children are mostly well adapted. Cardiovascular, renal, and metabolic function are still areas to be investigated. Larger studies are warranted to investigate areas other than cognition and behavior and to be able to draw more definitive conclusions about prenatal DEX treatment.

Abstract
PURPOSE Congenital adrenal hyperplasia (CAH) has been shown to potentially affect psychological adjustment. However, most research has focused on females, and knowledge about psychological challenges in males remains sparse. The aim of this systematic review was therefore to assess these in males with CAH. METHODS We systematically searched the OVID Medline, PsycINFO, CINAHL, and Web of Science databases, for articles published up to April 20, 2018, investigating psychological adjustment in males with CAH. RESULTS Eleven studies were included in the review. Three main health domains were identified: psychological and psychiatric health, quality of life (QoL), and self-perceptions of reproductive health. Some studies covered more than one health domain. Seven studies explored psychological adjustment and/or the presence of psychiatric symptoms or disorders. Results indicated that males with CAH had more problems related to internalizing behaviors (negative behaviors directed toward the self) and more negative emotionality compared to reference groups. Six studies examined QoL, five of them reporting reduced QoL compared to reference groups. Three studies explored the impact of fertility and sexual health issues on psychological health with varying results from impaired to normal sexual well-being. CONCLUSIONS CAH seems to have an impact on males' psychological health. However, the number of identified studies was limited, included few participants, and revealed divergent findings, demonstrating the need for larger studies and highlighting a number of methodological challenges that should be addressed by future research.

Abstract
We present a family with 2 members who received long-term steroid treatment for presumed classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, until molecular testing revealed nonclassic CAH, not necessarily requiring treatment. A 17-year-old male presented to our clinic on glucocorticoid and mineralocorticoid treatment for classic CAH. He was diagnosed at 4 years of age based on mild-moderate elevations of 17-hydroxyprogesterone (17-OHP) and adrenocorticotropic hormone (ACTH), but without evidence of precocious adrenarche/puberty. Due to his diagnosis, his clinically asymptomatic 3-year-old sister was tested and also found to have elevated ACTH and 17-OHP levels and was started on glucocorticoids for classic CAH. Family history revealed a healthy sibling who had no biochemical evidence of CAH and consanguineous healthy parents. We questioned the diagnosis of classic CAH and performed an ACTH1-24 stimulation test, which showed a level of 17-OHP in the borderline range between classic and nonclassic CAH. Molecular testing, using sequencing and multiplex ligation-dependent probe amplification analysis of CYP21A2, revealed that both affected siblings were compound heterozygotes for a whole-gene deletion and a, likely pathogenic (nonclassical), sequence variant, p.R124C. The asymptomatic father had the same genotype, while the mother showed one deleted copy and 2 active copies, making her an asymptomatic carrier. Our report demonstrates the importance of molecular testing in atypical cases of CAH, as well as the importance of both sequencing and deletion analysis. The results of molecular testing should be interpreted in clinical context, and treatment should be prescribed according to guidelines when available.

Abstract
RATIONALE Adrenal incidentaloma is sometimes complicated with 21-hydroxylase deficiency (21-OHD). Latent nonclassical 21-OHD in incidentaloma is difficult to diagnose. Although adrenalectomy in 21-OHD has been conducted when malignancy could not be excluded, adrenal insufficiency sometimes occurs, and it might not be observed immediately after operation. Here, we report a case of a 71-year-old man who experienced adrenal insufficiency over 2 decades postadrenalectomy, leading to a diagnosis of latent nonclassical 21-OHD. PATIENT CONCERNS A 71-year-old man was admitted to the hospital due to difficulty in movements and a sodium level of 119 mEq/L. His medical history revealed precocious puberty and left adrenalectomy because of an incidentaloma at 49 years of age, diagnosed pathologically as an adenoma. He did not attend follow-up visits because he did not have any symptoms. In 2017, 3 months before hospitalization, he experienced general fatigue. A few days before admittance, he complained of difficulty in moving and visual hallucination of small animals. DIAGNOSES Laboratory evaluations revealed a high level of adrenocorticotropic hormone (ACTH) and low cortisol level. ACTH-stimulating test revealed a low basal level and low response for cortisol, and a high basal level and low response for 17-hydroxyprogesterone. We analyzed large gene deletion or conversion and the 9 most common micro mutations in the CYP21A2 gene by polymerase chain reaction; micro mutation of I172N and heterozygous large gene deletion or conversion were detected leading to the diagnosis of nonclassical 21-OHD. INTERVENTIONS Immediately, 100 mg hydrocortisone was administered, followed by daily hydrocortisone and saline. The symptoms and hyponatremia improved in a few days. He was discharged from the hospital on day 34 with a daily dose of 15 mg hydrocortisone. LESSONS Clinicians should be aware of late onset of adrenal insufficiency after adrenalectomy. In such cases, clinicians should not overlook the latent nonclassical 21-OHD.

MacKay D, Nordenström A, Falhammar H. Bilateral Adrenalectomy in Congenital Adrenal Hyperplasia: A Systematic Review and Meta-Analysis. J Clin Endocrinol Metab 2018; 103:1767-1778. [PMID: 29554355 DOI: 10.1210/jc.2018-00217] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2018] [Accepted: 03/09/2018] [Indexed: 02/04/2023]
Abstract
CONTEXT Management of congenital adrenal hyperplasia (CAH) involves suppression of the hypothalamic-pituitary-adrenal axis using supraphysiological doses of exogenous glucocorticoids. This can pose a challenge, with Cushing syndrome a frequent complication of adequate suppression. Bilateral adrenalectomy, with subsequent replacement of glucocorticoids and mineralocorticoids at physiological doses, has been proposed as an alternative therapeutic strategy. OBJECTIVE To review the outcomes after bilateral adrenalectomy for CAH. DATA SOURCES A systematic search of PubMed/MEDLINE and Web of Science, identifying relevant reports published up to 10 January 2018. STUDY SELECTION Case reports or case series were included if they reported individual patient data from patients with CAH who had undergone bilateral adrenalectomy. DATA EXTRACTION Information regarding the following was extracted: first author, country, sex, age at adrenalectomy, year of adrenalectomy, diagnosis, molecular abnormality, pre- and postoperative biochemistry, pre- and postoperative medications, pre- and postoperative body mass index, indication for adrenalectomy, surgical technique, gross and microscopic adrenal characteristics, follow-up duration, and short- and long-term postoperative outcomes. DATA SYNTHESIS We identified 48 cases of bilateral adrenalectomy for CAH, with patients aged from 4 months to 56 years at surgery. The most common indication for surgery was the inability to control hyperandrogenism/virilization and/or Cushing syndrome (n = 30; 62%). Most patients (n = 34; 71%) reported symptomatic improvement postoperatively, with some cases of short-term (n = 5; 10%) and long-term (n = 13; 27%) adverse outcomes. CONCLUSIONS Bilateral adrenalectomy for CAH appears to be a reasonable therapeutic option for carefully selected patients who have had unsatisfactory outcomes with conventional medical management.

Abstract
OBJECTIVE The knowledge about health status in adults with disorder of sex development (DSD) is scarce. DESIGN AND METHODS A cross-sectional observational study in 14 European tertiary centers recruited 1040 participants (717 females, 311 males, 12 others) with DSD. Mean age was 32.4 ± 13.6 year (range 16-75). The cohort was divided into: Turner (n = 301), Klinefelter (n = 224), XY-DSD (n = 222), XX-DSD (excluding congenital adrenal hyperplasia (CAH) and 46,XX males) (n = 21), 46,XX-CAH (n = 226) and 45,X/46,XY (n = 45). Perceived and objective health statuses were measured and compared to European control data. RESULTS In DSD, fair to very good general health was reported by 91.4% and only 8.6% reported (very) bad general health (controls 94.0% and 6.0%, P < 0.0001). Longstanding health issues other than DSD and feeling limited in daily life were reported in 51.0% and 38.6%, respectively (controls 24.5% and 13.8%, P < 0.0001 both). Any disorder except DSD was present in 84.3% (controls 24.6%, P < 0.0001). Males reported worse health than females. In the subgroup analysis, Klinefelter and 46,XX-DSD patients reported bad general health in 15.7% and 16.7%, respectively (Turner 3.2% and CAH 7.4%). Comorbidities were prevalent in all DSD subgroups but Klinefelter and Turner were most affected. Early diagnosis of DSD and a healthy lifestyle were associated with less comorbidities. CONCLUSIONS Overall, general health appeared to be good but a number of medical problems were reported, especially in Klinefelter and Turner. Early diagnosis of DSD and a healthy lifestyle seemed to be important. Lifelong follow-up at specialized centers is necessary.

Abstract
Despite ethnic variation, 11 β-hydroxylase deficiency (11β-OHD) has generally been considered the second most common subtype of congenital adrenal hyperplasia (CAH). We report a high rate of novel mutations in this gene (CYP11B1) in patients from Saudi Arabia. We studied 16 patients with 11β-OHD from 8 unrelated families. DNA was isolated from peripheral blood. The 9 exons and exon-intron boundaries of CYP11B1 were PCR-amplified and directly sequenced. The novel mutations were functionally characterized using subcloning, in vitro mutagenesis, cell transfection and 11-deoxycortisol: cortisol conversion assays. Six mutations were found in these 8 unrelated families. Three of these mutations are completely novel and two have just been recently described as novel mutations from the same population. These include a single nucleotide insertion mutation in codon 18 (c.53_54insT) leading to frameshift and truncation in 4 siblings, a novel mutation (c.1343G>C, p.R448P) in 3 unrelated families, a novel mutation (c.1394A>T, p.H465L) in 2 siblings, a novel mutation (c.617G>T, p.G206V) in 1 patient, and a recently described non-sense novel mutation (c.780G>A, p.W260X) in another patient. Out of the 6 mutations described in this report, only one mutation (p.Q356X) was reported previously. In vitro functional testing of the 3 missense and nonsense novel mutations revealed complete loss of the 11 hydroxylase activity. We conclude that 11 β-OHD in Saudi Arabia has a unique genotype with a high rate of novel mutations. The novel p. R448P mutation is the most common mutation in this highly inbred population.

Abstract
The effects of long-term replacement therapy of adrenal insufficiency (AI) are still a matter of controversy. In fact, the established glucocorticoid replacement regimens do not completely reproduce the endogenous hormonal production and the monitoring of AI treatment may be a challenge for the lack of reliable clinical and biochemical markers. Consequently, several AI patients are frequently exposed to relative glucocorticoid excess potentially leading to develop chronic complications, such as diabetes mellitus, dyslipidemia, hypertension and fragility fractures with consequent impaired QoL and increased mortality risk. This review deals with the pathophysiological and clinical aspects concerning the over-replacement therapy of primary and secondary AI.

Abstract
CONTEXT Fertility in males with 21-hydroxylase deficiency (21OHD) is unclear. OBJECTIVE Study fertility outcome in males with congenital adrenal hyperplasia. DESIGN, SETTING, AND PARTICIPANTS Males ≥15 years old with 21OHD (n = 221) were compared with controls matched for sex and year and place of birth (n = 22,024). Data were derived by linking national population-based registers. Subgroup analyses were performed regarding phenotype [salt-wasting (SW), simple virilizing (SV), and nonclassic (NC)] and CYP21A2 genotype (null, I2 splice, I172N, and P30L) and stratified by the introduction of neonatal screening. MAIN OUTCOME MEASURES Number of biological and adopted children. RESULTS Males with 21OHD were less likely to be fathers of biological children [odds ratio (OR), 0.5; 95% confidence interval (CI), 0.4 to 0.7; after adjusting for socioeconomic characteristics: OR, 0.4; 95% CI, 0.2 to 0.5]. This was true for SW, SV, I2 splice, and I172N, but not for NC, null, and P30L groups (all adjusted). Among patients born before the neonatal screening introduction, fewer were fathers (adjusted OR, 0.3; 95% CI, 0.2 to 0.5), but this normalized in those born afterward. Adoption was more common in the 21OHD males (OR, 2.9; 95% CI, 1.0 to 7.9) and the SV and I172N subgroups. Age at becoming a father, marriage, region of residence, and education were similar, but fewer patients had high incomes. NC and I172N groups had, however, higher academic degrees and NC patients were more often married, whereas SW and I2 splice patients were more often divorced. CONCLUSIONS 21OHD was associated with a reduced frequency of biological children and an increased frequency of adopted children, suggesting impaired fertility, although some subgroups had normal fertility.

Abstract
Congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD-CAH) is an autosomal recessive disorder affecting steroidogenesis, due to mutations in CYP21A2 (6p21.3). 21OHD-CAH neonatal screening is based on 17-hydroxyprogesterone (17OHP) serum levels, showing high type I error rate and low sensitivity to mild CAH forms. Here, we used an epidemiological approach, which estimates the allelic frequency (q) of an autosomal recessive disorder using the proportion of homozygous patients, the mutational spectrum and the inbreeding coefficient in a sample of affected individuals. We applied this approach to 2 independent Italian cohorts of patients with both clinical and molecular diagnosis of 21OHD-CAH from mainland Italy (N = 240) and Sardinia (N = 53). We inferred q estimates of 2.87% and 1.83%, corresponding to a prevalence of 1/1214 and 1/2986, respectively. CYP21A2 mutational spectra were quite discrepant between the 2 cohorts, with V281L representing 74% of all the mutations detected in Sardinia vs 37% in mainland Italy. These findings provide an updated fine-grained picture of 21OHD-CAH genetic epidemiology in Italy and suggest the need for a screening approach suitable to the detection of the largest number of clinically significant forms of CAH.

Abstract
Mutations of CYP21A2 variably decrease 21-hydroxylase activity and result in a spectrum of disease expressions in patients with congenital adrenal hyperplasia (CAH). We examined the association between CYP21A2 mutations and virilization (Prader score) in females with CAH. The study population included 187 CAH females with fully characterized CYP21A2 mutations. One hundred fifty-eight patients were sorted into groups by expected enzyme activity (percent of normal activity) of the less severely affected allele: (A) null, 0%; (B) I2G, 1%; (C) I172N, 2%; and (D) V281L, >2%. We observed an inverse relationship between virilization and residual enzyme activity (P < 0.001). Subjects in group A or B had a significantly higher likelihood (unadjusted odds ratio: 16; P < 0.001) of developing severe virilization compared with those in group C. Surprisingly, 24% of group D patients, whose mutation is usually associated with nonclassical (NC) CAH, had severe virilization. Among subjects with the NC P30L mutation, 66% expressed unexpected virilization. Virilization, usually leading to extensive reconstructive surgery, is highly likely in patients with null or I2G mutations; however, NC mutations (P30L/V281L) may also lead to unexpected virilization. These findings have implications for prenatal counseling and highlight the need for additional investigations into other factors that influence virilization in CAH.

A population-based national cohort study. Clin Endocrinol (Oxf) 2017; 86:317-324.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000. About one in 70 individuals in the general population are carriers of a severe CYP21A2 mutation. It has been suggested that this confers a survival advantage, perhaps as a result of increased activity in the hypothalamic-pituitary-adrenal axis. We investigated vulnerability to psychological stress in obligate carriers. METHOD The Swedish CAH Registry encompasses more than 600 patients. Parents, that is obligate carriers of the CYP21A2 mutation, were identified through the Multigeneration Register. The diagnosis of the child was used as the psychological stressor. Psychiatric diagnoses before and after the birth of a child with CAH were compared to those of controls derived from (i) the general population, (ii) parents of children with hypospadias and (iii) parents of children with diabetes mellitus type 1 (T1DM). RESULTS Parents of children with CAH had less risk of being diagnosed with any psychiatric disorder (OR, 0·6), an affective disorder (OR, 0·5) or substance misuse (OR, 0·5) after the diagnosis of the child, compared to the general population. Their risk was also decreased compared to parents of a child with hypospadias (OR, 0·6, 0·4 and 0·2, respectively) and parents of a child with T1DM (OR 0·7, 0·6 and 0·2, respectively). The CYP21A2 carriers had a lower risk of developing mood and stress-related disorders after the diagnosis of the child. CONCLUSION Obligate CYP21A2 carriers had a reduced risk of a psychiatric diagnosis and were less vulnerable to a psychologically stressful situation, at least with respect to receiving a psychiatric diagnosis. This indicates a better ability to cope with psychological stress among heterozygous carriers of severe CYP21A2 mutations, which may contribute to the apparent survival advantage.
