Congenital adrenal hyperplasia

Adrenal myelolipomas (AML) are composed of mature adipose and hematopoietic components. They represent approximately 3 percent of adrenal tumors and are commonly found in patients with congenital adrenal hyperplasia (CAH). CAH provides a unique environment to explore AML pathogenesis. We aimed to evaluate the role of the immune system and hormones that accumulate in poorly controlled CAH in the development of AML. When compared to normal adrenal tissue, CAH-affected adrenal tissue and myelolipomas showed an increased expression of inflammatory cells ( CD68, IL2Rbeta ), stem cells ( CD117 ) B cells ( IRF4 ), and adipogenic markers ( aP2/FABP4, AdipoQ, PPARγ, Leptin, CideA ), and immunostaining showed nodular lymphocytic accumulation...

Hydrocortisone (HC) is the optimal drug for adolescents diagnosed with congenital adrenal hyperplasia (CAH). Because traditional dosage regimens HC are inconvenient, our study used fused deposition modeling (FDM) three-dimensional (3D) printing technology to solve the problems caused by traditional preparations. First, we designed a core-shell structure tablet with an inner instant release component and an outer delayed release shell. The instant release component was Kollicoat IR: glycerol (GLY): HC = 76...

INTRODUCTION: Quantifying differences in service provision for children and young people (CYP) living with Congenital Adrenal Hyperplasia (CAH) across the United Kingdom. METHODS: A national service evaluation using online questionnaires circulated to patients and clinicians from secondary and tertiary UK centres managing CYP with CAH, and via the "Living with CAH" support group mailing list. RESULTS: Total of 195 responses relating to patients aged 0-20 years attending 33 clinics (43 patients, 152 carers), as well as 34 clinicians from 18 trusts working across the 33 clinics...

CONTEXT: The outcomes related to cardiovascular risk (CVR) in patients with nonclassical form of congenital adrenal hyperplasia (NCAH) are unknown, especially those related to therapeutic options, including low doses of glucocorticoids (GCs) or oral contraceptive pills. OBJECTIVES: to analyze CVR by markers of atherosclerosis in females with nonclassical form according to therapeutic options. DESIGN AND SETTING: a cross-sectional study at a tertiary center...

This clinical case report details the comprehensive diagnosis and dental management of a seven-year-old female patient diagnosed with the rare genetic disorder, amelogenesis imperfecta and gingival fibromatosis syndrome (AIGFS). The case initially presented as congenital adrenal hyperplasia and amelogenesis imperfecta, but further genetic analysis revealed the involvement of AIGFS due to a mutation in the FAM20A gene. Diagnosis, confirmed through whole exome sequencing, clinical assessment, and laboratory tests, necessitated a multidisciplinary approach to address the treatment of such cases...

PURPOSE: Deficiency of 21-hydroxylase (21-OHD) is an autosomal recessively inherited disorder that is characterized by adrenal insufficiency and androgen excess. This study was performed to investigate the clinical utility of prenatal diagnosis of 21-OHD using molecular genetic testing in families at risk. METHODS: This study included 27 pregnant women who had previously borne a child with 21-OHD. Fetal tissues were obtained using chorionic villus sampling (CVS) or amniocentesis...

BACKGROUND: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder characterized by impaired activity of the enzyme required for cortisol and aldosterone production, resulting in increased adrenal androgen synthesis. Factors affecting fertility in CAH patients include ambiguous genitalia and their complications, excessive androgen secretion, adrenal progesterone hypersecretion, and various psychosocial factors. Serum anti-Müllerian hormone (AMH) level is used to assess ovarian reserve in women...

Congenital adrenal hyperplasia (CAH) is a term that encompasses a wide range of conditions that affect the adrenals. Diagnosis and treatment before birth are important as irreparable birth defects can be avoided, decreasing the need for surgical intervention later in life, especially regarding genitalia anomalies. Although early implementation of dexamethasone in the prenatal treatment of CAH has been controversial, there is recent evidence that this treatment can reduce long-term complications.

Thousands of non-human mammal experiments have demonstrated that early androgen exposure exerts long-lasting effects on neurobehavioural sexual differentiation. In humans, females with classic congenital adrenal hyperplasia (CAH) are exposed to unusually high concentrations of androgens prenatally, whereas prenatal concentrations of androgens in males with CAH are largely normal. The current meta-analysis included 20 independent samples and employed multi-level meta-analytic models. Consistently across all 7 male-typical and female-typical play outcomes, in the expected directions, the present study found significant and large average differences between control males and control females (gs = 0...

PURPOSE: To present our surgical experience and outcomes in congenital adrenal hyperplasia (CAH) patients with severe virilization using a combined technique of total urogenital mobilization (TUM) and a modified pull-through vaginoplasty to perform a safe and effective one-stage feminizing genital reconstruction for these children. METHODS: Fourteen CAH patients with severe virilization, defined by a Prader IV and V rating of the external genitalia, underwent TUM followed by a limited vaginal pull-through procedure from June 2016 to December 2020...

Precocious puberty, characterised by the early appearance of secondary sexual characteristics, poses challenges in diagnosis and management. Here, we describe a case of precocious puberty diagnosed in a boy in middle childhood, who presented with progressive phallus enlargement, pubic hair development and increased aggressive behaviour. Hormonal evaluation confirmed the diagnosis of congenital adrenal hyperplasia (CAH), complicated by gonadotropin-dependent precocious puberty. The case highlights the importance of assessment of testicular volume in a patient presenting with precocious puberty...

PURPOSE: Congenital Adrenal Hyperplasia (CAH) is one of the highly prevalent autosomal recessive endocrine disorders. The majority of CAH cases result from mutations in the CYP21A2 gene, leading to 21-hydroxylase deficiency. However, with the pseudogene-associated challenges in CYP21A2 gene analysis, routine genetic diagnostics and carrier screening in CAH are not a part of the first-tier investigations in a clinical setting. Furthermore, there is a lack of data on the carrier frequency for 21-OH deficiency...

OBJECTIVE: To explore the correlation between different CYP21A2 pathogenic gene mutations and clinical phenotypes in Congenital adrenal hyperplasia (CAH) patients. Moreover, combined with the specific phenotypes of patients in the clinic, diagnosis and treatment suggestions should be made for CAH patients. METHODS: In this study, a genetic status of a Chinese family in three generations of 21-hydroxylase deficiency was comprehensively presented, and the pathogenic genes in the family were found and traced in detail...

Beckwith-Wiedemann syndrome (BWS) is a common genetic congenital disease characterized by somatic overgrowth and its broad clinical spectrum includes pre- and post-natal macrosomia, macroglossia, visceromegaly, increased risk of neonatal hypoglycemia, and development of embryonic tumors. BWS occurs due to genetic/epigenetic changes involving growth-regulating genes, located on region 11p15, with an important genotype-phenotype correlation. Congenital adrenal hyperplasia (CAH) comprises a spectrum of autosomal recessive diseases presenting a variety of clinical manifestations due to a deficiency in one of the enzymes involved in cortisol secretion...

PURPOSE: 11β-hydroxylase deficiency (11β-OHD) constitutes a rare form of congenital adrenal hyperplasia (CAH), typically accounting for ~5-8% of CAH cases. Non-classical 11β-OHD is reported even more rarely and frequently results in misdiagnosis or underdiagnosis due to its mild clinical symptoms. METHODS: A clinical, biochemical, radiological, and genetic study was conducted on a 9-year-old girl presenting with mild breast development, axillary hair growth, and advanced bone age...

BACKGROUND: Adrenal Hypoplasia Congenita (AHC) is a rare subtype of primary adrenal insufficiency (PAI) that can go undiagnosed easily. In this article, we report two brothers with hypogonadotropic hypogonadism and novel mutations in the NR0B1 gene who were misdiagnosed and mismanaged as having congenital adrenal hypoplasia (CAH) for several years. CASE PRESENTATION: Herein, we describe two brothers with similar histories; first, they were diagnosed with CAH and treated for that; however, after several years, they showed symptoms of lack of testosterone despite receiving CAH treatment...

CONTEXT: Patients with primary adrenal insufficiency due to congenital adrenal hyperplasia (CAH) are at risk for adrenal crisis during infectious illnesses. Increased risk of infection including COVID-19 has been variably reported. OBJECTIVE: To evaluate COVID-19 illness outcomes and stress dose practices in a large cohort of patients with CAH during the first two years of the pandemic and compare observations of COVID-19 infection in patients with CAH to the general USA population...

Nonclassic congenital adrenal hyperplasia (NCCAH) is characterized by mild cortisol deficiency, excess androgens and adrenocorticotropin (ACTH) production, and often with various features of dysmetabolic syndrome. Elective bariatric surgery is one of the most effective long-term management strategies for severe obesity. Our case presents a 34-year-old woman with symptomatic NCCAH and class III obesity who status post Roux-en-Y gastric bypass (RYGB) had significant weight loss with metabolic resolution of NCCAH, and no longer required glucocorticoid (GC) therapy...

The phenomenon of a wandering spleen is rare with few published case reports. The cases published in the literature mainly result from acquired or congenital laxity of the spleen's anchoring ligaments. Our case demonstrates an uncommon complication and possibly the first reported case of an iatrogenic wandering spleen. We present an interesting case of a 51-year-old female patient with congenital adrenal hyperplasia, fibromyalgia, and rheumatoid arthritis who underwent robotic-assisted left adrenalectomy for a 10-cm adrenal mass...

INTRODUCTION: Patients with classical congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency exhibit an increased prevalence of obesity from childhood including central adiposity and inflammation. There is also an emerging affected brain phenotype in CAH, with decreased cortico-limbic gray matter volumes and white matter abnormalities. We aimed to study the relationship between brain structure, obesity, and inflammation in children and adolescents with CAH compared to controls...
