Abstract
CONTEXT Exposure to chronic stress and hypercortisolism is associated with decreased leukocyte telomere length (LTL), a marker for biological aging and cardiovascular disease. Children with congenital adrenal hyperplasia (CAH) are treated with glucocorticoids. OBJECTIVE To investigate LTL in children with CAH. METHODS In this prospective observational cohort study, conducted at 4 academic pediatric endocrinology outpatient clinics, children with genetically confirmed CAH were assessed at 2 follow-up visits (mean 4.1 ± 0.7 months apart). At each visit, LTL was determined by quantitative real-time PCR. All subjects underwent detailed clinical and endocrinologic evaluation and were classified as undertreated, optimally treated, or overtreated, accordingly. The influence of clinical factors on LTL was investigated using linear mixed models adjusted for age, sex, and BMI-z. RESULTS We studied 76 patients, of whom 31 (41%) were girls, 63 (83%) had classic CAH, 67 (88%) received hydrocortisone, and 8 (11%) prednisolone. Median age at first visit was 12.0 years (IQR, 6.3-15.1), and median BMI-z was 0.51 (IQR, -0.12 to 1.43). LTL was shorter in patients with classic vs nonclassic CAH (-0.29, P = 0.012), in overtreated than in optimally treated patients (-0.07, P = 0.002), and patients receiving prednisolone compared with hydrocortisone (-0.34, P < 0.001). LTL was not associated with undertreatment or daily hydrocortisone-equivalent dose (P > 0.05). CONCLUSION LTL is shorter in patients with classic than nonclassic CAH, and in those who are overtreated with hydrocortisone or treated with long-acting glucocorticoids. These findings may be attributed to chronic exposure to supraphysiologic glucocorticoid concentrations and indicate that LTL may be used as a biomarker for monitoring glucocorticoid treatment.

Modified-release hydrocortisone is associated with lower plasma renin activity in patients with salt-wasting congenital adrenal hyperplasia. Eur J Endocrinol 2023; 188:6991929.

Abstract
OBJECTIVE Poorly controlled salt-wasting (SW) congenital adrenal hyperplasia (CAH) patients often require high 9α-fluorocortisol doses as they show high levels of 17-hydroxyprogesterone (17OHP), which is a mineralocorticoid (MC)-receptor antagonist. DESIGN We investigated the renin-angiotensin-aldosterone system in patients with SW-CAH receiving twice daily modified-release hydrocortisone (MR-HC, Efmody) compared with standard glucocorticoid (GC) therapy. METHODS Data were analyzed from the 6-month, phase 3 study of MR-HC (n = 42) versus standard GC therapy (n = 41). MC replacement therapy remained unchanged throughout the study. Blood pressure, serum potassium, serum sodium, plasma renin activity (PRA), and serum 17OHP and androstenedione concentrations were analyzed at baseline, 4, 12, and 24 weeks. RESULTS The median serum 17OHP in the morning was significantly lower on MR-HC compared with standard GC at 24 weeks (2.5 nmol L-1 (IQR 8.3) versus 10.5 nmol L-1 (IQR 55.2), P = .001). PRA decreased significantly from baseline to 24 weeks in patients on MR-HC (0.83 ng L-1 s-1 (IQR 1.0) to 0.48 ng L-1 s-1 (IQR 0.61), P = .012) but not in patients on standard GC (0.53 ng L-1 s-1 (IQR 0.66) to 0.52 ng L-1 s-1 (IQR 0.78), P = .613). Serum sodium concentrations increased from baseline to 24 weeks in patients on MR-HC (138.8 ± 1.9 mmol L-1 to 139.3 ± 1.8 mmol L-1, P = .047), but remained unchanged on standard GC (139.8 ± 1.6 mmol L-1 to 139.3 ± 1.9 mmol L-1, P = .135). No significant changes were seen in systolic and diastolic blood pressure and serum potassium levels. CONCLUSION 6 months of MR-HC therapy decreased PRA and increased sodium levels indicating a greater agonist action of the 9α-fluorocortisol dose, which may be due to the decreased levels of the MC-receptor antagonist 17OHP.

Abstract
Most children with non-classic congenital adrenal hyperplasia (NC-CAH) due to 21-hydroxylase deficiency are asymptomatic and do not require cortisol replacement therapy unless they develop symptoms of hyperandrogenemia. The current practice is to treat symptomatic children with hydrocortisone aimed at suppressing excess adrenal androgen production irrespective of the child's level of endogenous cortisol production. Once on hydrocortisone therapy, even children with normal cortisol production require stress dosing. Some children with NC-CAH may present with premature adrenarche, growth acceleration, and advanced bone age, but with no signs of genital virilization and normal endogenous cortisol production. In these cases, an alternative therapy to hydrocortisone treatment that does not impact the hypothalamic-pituitary-adrenal axis, but targets increased estrogen production and its effects on bone maturation, could be considered. Aromatase inhibitors (AIs), which block the aromatization of androgen to estrogen, have been used off-label in men with short stature to delay bone maturation and as an adjunct therapy in children with classic CAH. The use of AI as a monotherapy for children with NC-CAH has never been reported. We present three pre-pubertal female children with a diagnosis of NC-CAH treated with anastrozole monotherapy after presenting with advanced bone age, early adrenarche, no signs of genital virilization, and normal peak cortisol in response to ACTH stimulation testing. Bone age z-scores normalized, and all three reached or exceeded their target heights. Monotherapy with anastrozole can be an effective alternative in slowing down bone maturation and improving height outcomes in children with NC-CAH and normal adrenal cortisol production.

Abstract
21-hydroxylase deficiency (21-OHD) is the most common form of congenital adrenal hyperplasia. In most developed countries, newborn screening enables diagnosis of 21-OHD in asymptomatic patients during the neonatal period. In addition, recent advances in genetic testing have facilitated diagnosing 21-OHD, particularly in patients with equivocal clinical information. On the other hand, many challenges related to treatment remain. The goals of glucocorticoid therapy for childhood 21-OHD are to maintain growth and maturation as in healthy children by compensating for cortisol deficiency and suppressing excess adrenal androgen production. It is not easy to calibrate the glucocorticoid dosage accurately for patients with 21-OHD. Auxological data, such as height, body weight, and bone age, are considered the gold standard for monitoring of 21-OHD, particularly in prepuberty. However, these data require months to a year to evaluate. Theoretically, biochemical monitoring using steroid metabolites allows a much shorter monitoring period (hours to days). However, there are many unsolved problems in the clinical setting. For example, many steroid metabolites are affected by the circadian rhythm and timing of medication. There is still a paucity of evidence for the utility of biochemical monitoring. In the present review, we have attempted to clarify the knowns and unknowns about treatment parameters in 21-OHD during childhood.

Measuring steroids in hair opens up possibilities to identify congenital adrenal hyperplasia in developing countries. Clin Endocrinol (Oxf) 2023; 98:41-48. [PMID: 35514026 PMCID: PMC10084416 DOI: 10.1111/cen.14754] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 04/16/2022] [Accepted: 04/25/2022] [Indexed: 12/16/2022]
Abstract
OBJECTIVE Patients with congenital adrenal hyperplasia (CAH) in developing countries have limited access to appropriate laboratory facilities for diagnosis and follow-up. The aim of this study is to evaluate steroid measurement in hair as a diagnostic tool to identify and monitor CAH in these patients. DESIGN A method was developed to measure steroids in hair, the stability of steroids in hair was assessed, and the concentration range in healthy volunteers was determined. Hair samples of patients, before and after starting therapy, were transported at ambient temperature to The Netherlands for analysis. PATIENTS Twenty-two Indonesian CAH patients and 84 healthy volunteers participated. MEASUREMENTS Cortisol, 17-hydroxyprogesterone (17OHP), androstenedione, and testosterone in hair were measured by liquid chromatography with tandem mass spectrometry. RESULTS Steroids in hair could be measured and remained stable (<4.9% deviation) for at least 3 weeks at 4°C and 30°C. In each of the untreated patients, hair concentrations of 17OHP (9.43-1135 pmol/g), androstenedione (36.1-432 pmol/g), and testosterone (2.85-69.2 pmol/g) were all above the upper limit of the corresponding range in healthy volunteers; 5.5 pmol/g, 13 pmol/g, and 1.8 pmol/g, respectively. After starting glucocorticoid treatment, the steroid concentrations in the hair of CAH patients decreased significantly for androstenedione (73%) and testosterone (59%) after 6 months. CONCLUSIONS CAH could be confirmed in Indonesian patients based on the concentration of 17OHP, androstenedione, and testosterone in hair, and a treatment effect was observed. These findings open up opportunities to diagnose and/or monitor CAH in developing countries with a simple noninvasive technique.

Abstract
OBJECTIVE Congenital adrenal hyperplasia (CAH) requires exogenous steroid replacement. Treatment is commonly monitored by measuring 17-OH progesterone (17OHP) and androstenedione (D4). DESIGN Retrospective cohort study using real-world data to evaluate 17OHP and D4 in relation to hydrocortisone (HC) dose in CAH patients treated in 14 countries. PATIENTS Pseudonymized data from children with 21-hydroxylase deficiency (21OHD) recorded in the International CAH Registry. MEASUREMENTS Assessments between January 2000 and October 2020 in patients prescribed HC were reviewed to summarise biomarkers 17OHP and D4 and HC dose. Longitudinal assessment of measures was carried out using linear mixed-effects models (LMEM). RESULTS Cohort of 345 patients, 52.2% female, median age 4.3 years (interquartile range: 3.1-9.2) were taking a median 11.3 mg/m2 /day (8.6-14.4) of HC. Median 17OHP was 35.7 nmol/l (3.0-104.0). Median D4 under 12 years was 0 nmol/L (0-2.0) and above 12 years was 10.5 nmol/L (3.9-21.0). There were significant differences in biomarker values between centres (p < 0.05). Correlation between D4 and 17OHP was good in multiple regression with age (p < 0.001, R2 = 0.29). In longitudinal assessment, 17OHP levels did not change with age, whereas D4 levels increased with age (p < 0.001, R2 = 0.08). Neither biomarker varied directly with dose or weight (p > 0.05). Multivariate LMEM showed HC dose decreasing by 1.0 mg/m2 /day for every 1 point increase in weight standard deviation score. DISCUSSION Registry data show large variability in 17OHP and D4 between centres. 17OHP correlates with D4 well when accounting for age. Prescribed HC dose per body surface area decreased with weight gain.

Abstract
PURPOSE This study aimed to investigate the utility of annual growth velocity (GV) standard deviation scores (SDSs) and compatibility and effectiveness of biochemical parameters in long-term treatment monitoring and management of 21-hydroxylase deficiency (21-OHD) in children. METHODS Fifty children with 21-OHD were included in this study, and the biochemical parameters obtained during 402 visits were retrospectively evaluated. The follow-up period was divided between two GV SDS groups (GV SDS < 2 and GV SDS ≥ 2) and compared with auxological, biochemical, and clinical findings. RESULTS Elevation of 17-hydroxyprogesterone (17-OHP) values was observed at 193/402 visits, and both adrenocorticotropic hormone (ACTH) and total testosterone (tT) were observed at 53 of 193 (27.5%) visits. The calculated cut-off value for 17-OHP was > 4.3 ng/ml, with a sensitivity of 85.48% and specificity of 37.59% in the GV SDS ≥ 2 group. In the GV SDS ≥ 2 group, the corrected final height SDS (cFH SDS) was lower, and the delta height was higher than in the GV SDS < 2 group (p = 0.005 and p = 0.008, respectively). Linear regression analysis of the GV SDSs revealed that 17-OHP values and the hydrocortisone dose (mg/m2) were affected (β = 0.037, p = 0.035, and β = - 0.147, p = 0.001, respectively). CONCLUSIONS Annual GV was critical in the final height (FH) of children with 21-OHD. However, we observed inconsistency between the biochemical parameters in the follow-ups, and there were difficulties in evaluating these markers. Therefore, annual GV SDSs and biochemical findings should be used together in patients with 21-OHD at follow-ups.

Abstract
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder, and 17α-hydroxylase deficiency (17α-OHD) is a rare type of CAH. 17α-OHD is caused by CYP17 gene mutation, resulting in partial or complete deficiency of 17α-hydroxylase, which in turn leads to the lack of cortisol and sex hormone production. The disease is manifested by excessive secretion of adrenocorticotropic hormone (ACTH), decreased levels of estradiol (E2) and androgen, elevated levels of proges-terone (P), follicle stimulating hormone (FSH), and luteinizing hormone (LH). Most of the patients are female in gender. According to the chromosome karyotype, 17α-OHD can be divided into 46XX and 46XY, of which 46XX is rarer. The clinical manifestations are hypokalemia and hypertension. Patients with 46XX-karyotype may have irregular menstruation, amenorrhea, and infertility. The severity of symptoms varies according to the degree of 17α-hydroxylase deficiency. Due to its untypical manifestation, the patients with partial 17α-OHD are more likely to be missed or misdiagnosed. Some 17α-OHD patients with 46, XX karyotypes have different degrees of development of internal and external reproductive organ and spontaneous menstrual cycle, so they may have the potential ovulation and fertility opportunities. However, due to the adverse effects of high serum P level on the endometrium, the patients would have infertility problems. To date, four cases from foreign countries have been reported about the infertility treatments among 46XX-17α-OHD patients, and two cases were mentioned in China without describing the process of treatments. Here, one case with partial 46XX-17α-OHD was diagnosed and successfully conceived and delivered after in vitro fertilization-embryo transfer (IVF-ET) in the Center for Reproductive Medicine, Peking University Third Hospital. Controlled ovarian stimulation with ultra-long protocol was initiated after glucocorticoid therapy was given to reduce P level. Ten oocytes were obtained and 6 embryos were cryopreserved. Frozen-thawed embryo transfer under hormonal replacement after gonadotropin releasing hormone agonist (GnRH-a) was carried out in an artificial cycle, and then the patient was successfully pregnant and delivered a healthy boy after 37 weeks of gestation by cesarean section. The treatment of this case suggests that patients with partial 46XX-17α-OHD can obtain oocytes and embryos with good quality. IVF combined with frozen-thawed embryo transfer under artificial cycle is an effective method for patients with partial 46XX-17α-OHD with infertility.

Abstract
CONTEXT Congenital generalized lipodystrophy, type 1 (CGL1), due to biallelic pathogenic variants in AGPAT2, is characterized by the near total loss of body fat from the face, trunk, and extremities. Patients develop premature diabetes, hypertriglyceridemia, hepatic steatosis, and polycystic ovary syndrome. However, sparing of the facial fat and precocious pubertal development has not been previously reported in CGL1. CASE DESCRIPTION We report a 21-year-old woman of European descent with CGL1 who had sparing of the facial fat and premature thelarche at birth with premature pubarche and menstrual bleeding at age 3 years. Her serum 17-OH progesterone level rose to 1000 ng/dL (30.26 nmol/L) after cosyntropin stimulation test, suggestive of nonclassical congenital adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency. Hydrocortisone replacement therapy from age 3.5 to 10 years resulted in cessation of menstruation and growth of pubic hair, and a reduction of breast size. Sanger and whole-exome sequencing revealed compound heterozygous variants c.493-1G>C; p.(Leu165_Gln196del), and c.del366_588+534; p.(Leu123Cysfs*55) in AGPAT2 plus c.806G>C; p.(Ser269Thr) and c.844G>T; p.(Val282Leu) in CYP21A2. She developed diabetes at age 13 requiring high-dose insulin and had 7 episodes of acute pancreatitis due to extreme hypertriglyceridemia in the next 5 years. Metreleptin therapy was initiated at age 18 and after 3 years, she had remission of diabetes and hypertriglyceridemia; however, menstrual irregularity and severe hirsutism did not improve. CONCLUSION Concomitant NCAH in this CGL1 patient was associated with precocious pubertal development and sparing of facial fat. Metreleptin therapy drastically improved her hyperglycemia and hyperlipidemia but not menstrual irregularity and hirsutism.

Abstract
OBJECTIVES To evaluate the anthropometric and pubertal outcomes, over a spectrum of treatment regimens and compliance. METHODS We reviewed records of the patients with classical CAH seen at the endocrinology clinic of a tertiary care center between 1995 and 2016. RESULTS 25 females were included in the study, the majority (80%) with simple virilizing variant. All patients had genital ambiguity since birth, yet 40% (10/25) presented much later with menstrual complaints. All patients received hydrocortisone, but some switched to dexa-methasone (n=7) or prednisolone (n=4). 7/9 (77.9%) girls who achieved target height, were on hydrocortisone. Menarche occurred with corticosteroid treatment in 60% (15/25) patients at a median (IQR) age of 16 (12-22) years. CONCLUSION Hydrocortisone seems to have a beneficial effect on linear growth. Once target height is achieved, dexamethasone may be considered as an alternative.

Abstract
OBJECTIVE Treatment of congenital adrenal hyperplasia (CAH) patients with glucocorticoids is often challenging since there is a delicate balance between over- and undertreatment. Treatment can be monitored noninvasively by measuring salivary androstenedione (A4) and 17-hydroxyprogesterone (17-OHP). Optimal treatment monitoring requires the establishment of reference values in saliva. DESIGN A descriptive study. PATIENTS For this study saliva of 255 healthy paediatric and adult volunteers with an age range of 4-75 years old was used. MEASUREMENTS We developed a sensitive liquid chromatography-tandem mass spectrometry method, assessed salivary A4 and 17-OHP stability, and measured A4 and 17-OHP concentrations in saliva collected in the morning, afternoon, and evening. RESULTS We quantified A4 and 17-OHP concentrations in the morning, afternoon, and evening and demonstrated that there is a significant rhythm with the highest levels in the morning and decreasing levels over the day. A4 and 17-OHP concentrations display an age-dependent pattern. These steroids remain stable in saliva at ambient temperature for up to 5 days. CONCLUSIONS Good stability of the steroids in saliva enables saliva collection by the patient at home. Since salivary A4 and 17-OHP display a diurnal rhythm and age-dependent pattern, we established reference values for both children and adults at three time points during the day. These reference values support treatment monitoring of children and adults with CAH.

Abstract
Treatment for congenital adrenal hyperplasia (CAH) was introduced in the 1950s following the discovery of the structure and function of adrenocortical hormones. Although major advances in molecular biology have delineated steroidogenic mechanisms and the genetics of CAH, management and treatment of this condition continue to present challenges. Management is complicated by a combination of comorbidities that arise from disease-related hormonal derangements and treatment-related adverse effects. The clinical outcomes of CAH can include life-threatening adrenal crises, altered growth and early puberty, and adverse effects on metabolic, cardiovascular, bone and reproductive health. Standard-of-care glucocorticoid formulations fall short of replicating the circadian rhythm of cortisol and controlling efficient adrenocorticotrophic hormone-driven adrenal androgen production. Adrenal-derived 11-oxygenated androgens have emerged as potential new biomarkers for CAH, as traditional biomarkers are subject to variability and are not adrenal-specific, contributing to management challenges. Multiple alternative treatment approaches are being developed with the aim of tailoring therapy for improved patient outcomes. This Review focuses on challenges and advances in the management and treatment of CAH due to 21-hydroxylase deficiency, the most common type of CAH. Furthermore, we examine new therapeutic developments, including treatments designed to replace cortisol in a physiological manner and adjunct agents intended to control excess androgens and thereby enable reductions in glucocorticoid doses.

Patients with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD) need life-long medical treatment to replace the lacking glucocorticoids and potentially lacking mineralocorticoids and to lower elevated adrenal androgens. Long-term complications are common, including gonadal dysfunction, infertility, and cardiovascular and metabolic co-morbidity with reduced quality of life. These complications can be attributed to the exposure of supraphysiological dosages of glucocorticoids and the longstanding exposure to elevated adrenal androgens. Development of novel therapies is necessary to address the chronic glucocorticoid overexposure, lack of circadian rhythm in glucocorticoid replacement, and inefficient glucocorticoid delivery with concomitant periods of hyperandrogenism. In this review we aim to give an overview about the current treatment regimens and its limitations and describe novel therapies especially evaluated for 21OHD patients.

Abstract
PURPOSE OF REVIEW Although the basic treatment of congenital adrenal hyperplasia (CAH) is well established, there are active clinical research projects to more closely mimic the normal diurnal rhythm of cortisol secretion and to reduce total glucocorticoid doses to minimize adverse metabolic effects. RECENT FINDINGS We review clinical studies on CAH treatment published in the last 18 months or currently underway according to ClinicalTrials.gov listings. These can be grouped into several broad themes: alternative dosing forms of hydrocortisone with altered pharmacokinetics or easier dose titration; corticotropin-releasing hormone receptor antagonists that reduce corticotropin (ACTH) secretion and thereby reduce adrenal androgen secretion; androgen biosynthesis inhibitors; a first clinical trial of a gene therapy vector. SUMMARY Alternative dosing forms of hydrocortisone are, or will shortly be, marketed, but cost may be a barrier to utilization, at least in the US market. Trials of corticotropin releasing hormone receptor antagonists and androgen biosynthesis inhibitors are currently underway. The author believes that trials of gene therapy for CAH are premature.

Abstract
CONTEXT The clinical use of dexamethasone (DEX) prenatally to reduce virilization of external genitalia in female fetuses with congenital adrenal hyperplasia (CAH) is efficient but still controversial. It remains challenging to prevent the excessive exposure of DEX in unborn healthy babies during the first trimester of pregnancy. OBJECTIVE Since endogenous glucocorticoids contribute to the maintenance of blood pressure (BP) and since events during fetal life may program the fetus and affect future metabolic health, the aim of this study was to analyze ambulatory BP measurements in CAH-unaffected children and adults that were prenatally exposed to DEX treatment. METHODS Ambulatory BP measurements were analyzed in 33 (16 female) DEX-treated participants aged 5.1 to 26.3 years (19 participants aged ≤ 18 years) and in 54 (28 female) age- and sex-matched apparently healthy controls aged 5.5 to 25.3 years (27 participants aged ≤ 18 years) with ambulatory normotension. RESULTS Participants' age, height, weight, and body mass index were similar between the DEX-treated group and the control group. Heart rate, 24-hour BP, pulse pressure, and nighttime dipping did not statistically significantly differ between DEX-treated participants and controls. CONCLUSION Our study suggests that prenatal DEX treatment in CAH-unaffected children and adults does not appear to adversely affect ambulatory BP later in life. Our observations need to be confirmed in larger studies.

Abstract
INTRODUCTION There is wide variation in reported rates of acute adrenal insufficiency (AI)-related adverse events (sick day episodes and adrenal crises) between centres. This study aimed to evaluate the level of consensus on criteria considered essential for defining and managing these events in children with Congenital Adrenal Hyperplasia. METHODS Active users of the International Congenital Adrenal Hyperplasia and International Disorders of Sex Development (I-CAH/I-DSD) Registries (n = 66), non-active users of I-CAH/I-DSD (n = 35), and the EuRRECa e-Reporting Registry (n = 10) were approached to complete an online survey. RESULTS Fifty-six centres from 27 countries responded to the survey; the response rates for the three groups were 42 (65%), 11 (31%), and 3 (30%), respectively. Steroid management plans, one to one patient education, and contact details of health care staff were provided by over 90% of centres in high-income countries. All 56 centres advised glucocorticoid stress dosing in the event of fever. Less common indications for sick day dosing included vaccination and mild afebrile intercurrent illness, recommended by 17 (30%) and 9 (16%) centres, respectively. The most frequently reported stress dosing regimens were tripling the total daily dose of hydrocortisone and administering 3 times daily and doubling or tripling the largest daily hydrocortisone dose depending on the nature of the trigger and administering 3 times daily, recommended by 24 (43%) and 21 (38%) centres, respectively. Vomiting was the most common indication for intramuscular hydrocortisone injection, reported by 34 (61%) centres. Over 50% of respondents indicated that essential clinical criteria for adrenal crisis should include fatigue and nausea or vomiting and over 60% indicated that hypotension, hyponatraemia, hyperkalaemia, and clinical improvement following parenteral glucocorticoids were essential criteria. In the event of an adrenal crisis, 47 (84%) reported that the majority of patients were admitted to hospital. For the management of an adrenal crisis, a bolus parenteral injection of hydrocortisone was the most frequently administered medication, reported by 50 (89%) centres. CONCLUSION Although there is variation in the definition and management of AI-related adverse events in children amongst centres, there is also a good level of consensus on specific aspects that can lead to greater benchmarking of care.

Abstract
OBJECTIVE Varying outcomes regarding the quality of life (QoL) have been reported in patients with congenital adrenal hyperplasia (CAH). To assess the impact of adherence rate to medical therapy regimens on QoL in patients with CAH. PATIENTS Adolescents and adults aged 15-72 years with CAH due to 21-hydroxylase deficiency at Karolinska University Hospital, Stockholm, Sweden. MEASUREMENTS QoL was assessed using the Addison QoL (n = 72) and RAND 36 questionnaires (n = 75). Adherence to therapy regimens was measured using the Adherence Starts with Knowledge questionnaire (ASK-12). Associations between QoL, type of glucocorticoid therapy prescribed and ASK-12 results were examined. Results were compared to reference RAND 36 data obtained from a representative sample from the general Swedish population. RESULTS A good adherence rate to therapy regimens and a younger age were key factors for a better QoL in study participants with CAH. Younger patients on hydrocortisone and with good adherence had higher RAND 36 scores than older patients on prednisolone independently adherence. Participants with classic CAH (both the salt-wasting and simple virilizing form) reported higher QoL than those with nonclassic CAH. Patients with CAH, especially nonclassic, more frequently reported an impaired QoL than the general population, especially regarding limitations related to body pain, vitality and mental health. CONCLUSION A poor adherence rate to therapy regimens, rather than type of glucocorticoid was associated with impaired QoL in adolescents and adults with CAH.

Abstract
BACKGROUND Prevalence of hypertension and hypertension-mediated organ damage (HMOD) had not been well studied in patients with 11β-hydroxylase deficiency (11β-OHD). OBJECTIVE The study was to assess the prevalence and risk factors of hypertension and HMOD in patients with 11β-OHD. DESIGN Retrospective cohort analysis in a single medical centre. PATIENTS Twenty-eight patients with 11β-OHD were recruited between January 2003 and June 2021, and their diagnosis had been confirmed by Sanger sequencing. MEASUREMENTS Blood pressure and clinical indicators for the assessment of HMOD occurrence were collected from the medical records. Medication adherence of antihypertensive drugs and glucocorticoids were determined by the patients' biochemistry. Logistic regression was used to identify factors associated with HMOD. RESULTS Prevalence of hypertension and HMOD in the cohort was 100% and 50%, respectively. The kidneys (71.43%) are the organ most commonly damaged by high blood pressure, followed by the heart (64.29%), eyes (57.14%) and brain (21.43%). Risk factors of HMOD were hypokalemia (odds ratio [OR]: 9.16; 95% confidence interval [CI]: 1.634-51.43; p = .012), blood pressure ≥ 180/110 mmHg (OR: 22.0, 95% CI: 3.08-157.34; p = .002) and irregular glucocorticoid use (OR: 3.18, 95% CI: 1.13-8.98; p = .021). Blood pressure ≥ 180/110 mmHg was an independent predictor for HMOD. CONCLUSION Hypertension and HMOD are prevalent in patients with 11β-OHD in our study. These findings illustrate the importance of early HMOD evaluation and optimal glucocorticoid medication in 11β-OHD patients.

Eur J Endocrinol 2022; 186:587-596. [PMID: 35290211 PMCID: PMC9066592 DOI: 10.1530/eje-21-1085] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Accepted: 03/15/2022] [Indexed: 12/04/2022]
Abstract
OBJECTIVES International guidelines recommend additional salt supplementation during infancy in classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. The influence of corticoid medication and growth has not been assessed. AIM To investigate the current use of salt supplementation, fludrocortisone (FC) and hydrocortisone (HC) dosage as well as weight, height, BMI and blood pressure (BP) in CAH children aged 0-3 years. METHODS Retrospective multicentre analysis using data from the I-CAH registry. Salt-treated (ST) and non-salt-treated (NST) children were compared regarding FC and HC dosage, weight, height and BP at 0, 3, 6, 9, 12, 18, 24, 30, and 36 months. RESULTS We analysed 2483 visits of 331 patients born after year 2000 in 13 countries (male, n = 145) with 203 ST patients (61%). NST children had significantly higher FC dosages at 1.5-4.5 months and higher HC dosages until 1.5 months of age. No differences in weight, length and BP between subgroups were observed. Children of the whole cohort showed increased BMI-SDS during the study period and about half of the reported BP readings were >P95. CONCLUSION In children treated with additional salt supplementation, FC and HC dosages are lower during the first months of life but without differences in weight, length and BP until 3 years of age compared to NST children. All children showed an increase in BMI-SDS and a high rate of BP readings >P95 until 3 years, indicating the start of weight gain and negative effects on blood pressure already in very early life.

Abstract
CONTEXT Hydrocortisone treatment of young patients with 21-hydroxylase deficiency (21OHD) is given thrice daily, but there is debate about the optimal timing of the highest hydrocortisone dose, either mimicking the physiological diurnal rhythm (morning), or optimally suppressing androgen activity (evening). OBJECTIVE We aimed to compare 2 standard hydrocortisone timing strategies, either highest dosage in the morning or evening, with respect to hormonal status throughout the day, nocturnal blood pressure (BP), and sleep and activity scores. METHODS This 6-week crossover study included 39 patients (aged 4-19 years) with 21OHD. Patients were treated for 3 weeks with the highest hydrocortisone dose in the morning, followed by 3 weeks with the highest dose in the evening (n = 21), or vice versa (n = 18). Androstenedione (A4) and 17-hydroxyprogesterone (17OHP) levels were quantified in saliva collected at 5 am; 7 am; 3 pm; and 11 pm during the last 2 days of each treatment period. The main outcome measure was comparison of saliva 17OHP and A4 levels between the 2 treatment strategies. RESULTS Administration of the highest dose in the evening resulted in significantly lower 17OHP levels at 5 am, whereas the highest dose in the morning resulted in significantly lower 17OHP and A4 levels in the afternoon. The 2 treatment dose regimens were comparable with respect to averaged daily hormone levels, nocturnal BP, and activity and sleep scores. CONCLUSION No clear benefit for either treatment schedule was established. Given the variation in individual responses, we recommend individually optimizing dose distribution and monitoring disease control at multiple time points.

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

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH), characterized by defective adrenal steroidogenesis, is transmitted in an autosomal recessive manner. Mutations in the steroid 21-hydroxylase gene CYP21A2 causing steroid 21-hydroxylase deficiency account for most cases of CAH. The c.145l-1452delGGinsC gene mutation is rare, and only one case has been reported, but the form of gene mutation is different from this case, resulting in different clinical phenotype. The most common pathogenic genotype of CAH is a homozygous or compound heterozygous mutation, but CAH patients homozygous for the p.I173N mutation and heterozygous for the c.1451-1452delGGinsC mutation have not been reported previously. We report herein a familial case of CAH, in which both siblings carry the rare homozygous p.I173N mutation and heterozygous c.1451-1452delGGinsC mutation. CASE PRESENTATION The proband showed amenorrhea, infertility, polycystic ovaries, and increased levels of androgen, rather than the typical clinical manifestations of CAH such as an adrenal crisis or masculine vulva, so was misdiagnosed with polycystic ovary syndrome for many years. Following a correct diagnosis of CAH, she was given glucocorticoid treatment, her menstruation became more regular, and she became pregnant and delivered a healthy baby girl. CONCLUSIONS The genotypes may be p.I173N homozygous or p.I173N/c.1451-1452delGGinsC heterozygous, both mutations could be pathogenic. This complex combination of mutations has not been reported or studied before. Through the report and analysis of this genotype, the content of CAH gene bank is enriched and the misdiagnosis rate of CAH is reduced.

Abstract
OBJECTIVE Insulin sensitivity evaluation by hyperinsulinemic-euglycemic clamp in nonclassical congenital adrenal hyperplasia (NC-CAH) due to 21-hydroxilase deficiency. DESIGN AND SETTING Cross-sectional study at university hospital outpatient clinics. PATIENTS AND METHODS NC-CAH patients (25 females, 6 males; 24 ± 10 years) subdivided into C/NC (compound heterozygous for 1 classical and 1 nonclassical allele) and NC/NC (2 nonclassical alleles) genotypes were compared to controls. RESULTS At diagnosis, C/NC patients presented higher basal and adrenocorticotropin-stimulated 17-hydroxyprogesterone and androstenedione levels than NC/NC genotype. Patients and controls presented similar weight, body mass index, abdominal circumference, and total fat body mass. NC-CAH patients showed higher waist-to-hip ratio, lower adiponectin and lower high-density lipoprotein cholesterol levels with no changes in fasting plasma glucose, glycated hemoglobin, homeostatic model assessment for insulin resistance, leptin, interleukin 6, tumor necrosis factor alpha, C-reactive protein, and carotid-intima-media thickness. All patients had used glucocorticoid (mean time of 73 months). Among the 22 patients with successful clamp, 13 were still receiving glucocorticoid-3 patients using cortisone acetate, 9 dexamethasone, and 1 prednisone (hydrocortisone equivalent dose of 5.5mg/m²/day), while 9 patients were off glucocorticoid but had previously used (hydrocortisone equivalent dose of 5.9mg/m2/day). The NC-CAH patients presented lower Mffm than controls (31 ± 20 vs 55 ± 23µmol/min-1/kg-1, P = 0.002). The Mffm values were inversely correlated with the duration of glucocorticoid treatment (r = -0.44, P = 0.04). There was association of insulin resistance and glucocorticoid type but not with androgen levels. CONCLUSION Using the gold standard method, the hyperinsulinemic-euglycemic clamp, insulin resistance was present in NC-CAH patients and related to prolonged use and long-acting glucocorticoid treatment. Glucocorticoid replacement and cardiometabolic risks should be monitored regularly in NC-CAH.

Abstract
CONTEXT Classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD) is characterized by impaired cortisol synthesis and excess androgen production. Corticotropin-releasing factor type 1 receptor (CRF1R) antagonism may decrease adrenal androgen production. OBJECTIVE This work aimed to evaluate the safety, tolerability, and efficacy of crinecerfont (NBI-74788), a selective CRF1R antagonist, in 21OHD. METHODS This open-label, phase 2 study, with sequential cohort design (NCT03525886), took place in 6 centers in the United States. Participants included men and women, aged 18 to 50 years, with 21OHD. Interventions included 4 crinecerfont regimens, each administered orally for 14 consecutive days: 50 or 100 mg once daily at bedtime (cohorts 1 and 2, respectively); 100 mg once daily in the evening (cohort 3); and 100 mg twice daily (cohort 4). Participants could enroll in more than 1 cohort. Main outcomes included changes from baseline to day 14 in adrenocorticotropin (ACTH), 17-hydroxyprogesterone (17OHP), androstenedione, and testosterone. RESULTS Eighteen participants (11 women, 7 men) were enrolled: cohort 1 (n = 8), cohort 2 (n = 7), cohort 3 (n = 8), cohort 4 (n = 8). Mean age was 31 years; 94% were White. Median percent reductions were more than 60% for ACTH (-66%), 17OHP (-64%), and androstenedione (-64%) with crinecerfont 100 mg twice a day. In female participants, 73% (8/11) had a 50% or greater reduction in testosterone levels; male participants had median 26% to 65% decreases in androstenedione/testosterone ratios. CONCLUSION Crinecerfont treatment for 14 days lowered ACTH and afforded clinically meaningful reductions of elevated 17OHP, androstenedione, testosterone (women), or androstenedione/testosterone ratio (men) in adults with 21OHD. Longer-term studies are required to evaluate the effects of crinecerfont on clinical end points of disordered steroidogenesis and glucocorticoid exposure in patients with 21OHD.
