A group of inherited disorders of the ADRENAL GLANDS, caused by enzyme defects in the synthesis of cortisol (HYDROCORTISONE) and/or ALDOSTERONE leading to accumulation of precursors for ANDROGENS. Depending on the hormone imbalance, congenital adrenal hyperplasia can be classified as salt-wasting, hypertensive, virilizing, or feminizing. Defects in STEROID 21-HYDROXYLASE; STEROID 11-BETA-HYDROXYLASE; STEROID 17-ALPHA-HYDROXYLASE; 3-beta-hydroxysteroid dehydrogenase (3-HYDROXYSTEROID DEHYDROGENASES); TESTOSTERONE 5-ALPHA-REDUCTASE; or steroidogenic acute regulatory protein; among others, underlie these disorders.
An adrenal microsomal cytochrome P450 enzyme that catalyzes the 21-hydroxylation of steroids in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP21 gene, converts progesterones to precursors of adrenal steroid hormones (CORTICOSTERONE; HYDROCORTISONE). Defects in CYP21 cause congenital adrenal hyperplasia (ADRENAL HYPERPLASIA, CONGENITAL).
An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.
A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.
A metabolite of PROGESTERONE with a hydroxyl group at the 17-alpha position. It serves as an intermediate in the biosynthesis of HYDROCORTISONE and GONADAL STEROID HORMONES.
Pathological processes of the ADRENAL GLANDS.
Excess production of ADRENAL CORTEX HORMONES such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE. Hyperadrenal syndromes include CUSHING SYNDROME; HYPERALDOSTERONISM; and VIRILISM.
A metabolite of 17-ALPHA-HYDROXYPROGESTERONE, normally produced in small quantities by the GONADS and the ADRENAL GLANDS, found in URINE. An elevated urinary pregnanetriol is associated with CONGENITAL ADRENAL HYPERPLASIA with a deficiency of STEROID 21-HYDROXYLASE.

Adrenal cortex function is regulated by pituitary ADRENOCORTICOTROPIN.
Neoplasm derived from displaced cells (rest cells) of the primordial ADRENAL GLANDS, generally in patients with CONGENITAL ADRENAL HYPERPLASIA. Adrenal rest tumors have been identified in TESTES; LIVER; and other tissues. They are dependent on ADRENOCORTICOTROPIN for growth and adrenal steroid secretion.

It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.
An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).

In utero exposure to FLUCONAZOLE, as well as mutations in at least two separate genes are associated with this condition - POR (encoding P450 (cytochrome) oxidoreductase (NADPH-FERRIHEMOPROTEIN REDUCTASE)) and FGFR2 (encoding FIBROBLAST GROWTH FACTOR RECEPTOR 2).
A synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of ADRENOCORTICOTROPIC HORMONE. ACTH (1-24), a segment similar in all species, contains the biological activity that stimulates production of CORTICOSTEROIDS in the ADRENAL CORTEX.

The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.

An anti-inflammatory 9-fluoro-glucocorticoid.
Defects in the SEX DETERMINATION PROCESS in 46, XY individuals that result in abnormal gonadal development and deficiencies in TESTOSTERONE and subsequently ANTIMULLERIAN HORMONE or other factors required for normal male sex development. This leads to the development of female phenotypes (male to female sex reversal), normal to tall stature, and bilateral streak or dysgenic gonads which are susceptible to GONADAL TISSUE NEOPLASMS. An XY gonadal dysgenesis is associated with structural abnormalities on the Y CHROMOSOME, a mutation in the GENE, SRY, or a mutation in other autosomal genes that are involved in sex determination.
An infant during the first month after birth.
A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.
Abnormally low potassium concentration in the blood. It may result from potassium loss by renal secretion or by the gastrointestinal route, as by vomiting or diarrhea. It may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities (depression of the T wave and elevation of the U wave), by renal disease, and by gastrointestinal disorders.

A period in the human life in which the development of the hypothalamic-pituitary-gonadal system takes place and reaches full maturity. The onset of synchronized endocrine events in puberty lead to the capacity for reproduction (FERTILITY), development of secondary SEX CHARACTERISTICS, and other changes seen in ADOLESCENT DEVELOPMENT.
Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis.

Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed)
Solitary or multiple benign hepatic vascular tumors, usually occurring in women of 20-50 years of age. The nodule, poorly encapsulated, consists of a central stellate fibrous scar and normal liver elements such as HEPATOCYTES, small BILE DUCTS, and KUPFFER CELLS among the intervening fibrous septa. The pale colored central scar represents large blood vessels with hyperplastic fibromuscular layer and narrowing lumen.

Mutation screening in British 21-hydroxylase deficiency families and development of novel microsatellite based approaches to prenatal diagnosis. (1/446)

21-hydroxylase deficiency is a recessively inherited disorder of steroidogenesis, resulting from mutations in the CYP21 gene. This 3.5 kb gene and a highly related CYP21P pseudogene reside on tandemly duplicated 30 kb segments of DNA in the class III HLA region, and the great majority of pathogenic mutations result from sequence exchanges involving the duplicated units. We now describe a comprehensive survey of CYP21 mutations in the British population, encompassing a screen for 17 different mutations in a total of 284 disease chromosomes. The most common mutations were as follows: large scale deletions/conversions (45% of the affected chromosomes), the intron 2 splice mutation (30.3%), R357W (9.8%), and I172N (7.0%). Mutations were detected in over 92% of the chromosomes examined, suggesting that accurate DNA based diagnosis is possible in most cases using the described strategy. In order to extend highly accurate prenatal diagnosis to all families where samples are available from a previously affected child, we have developed a linkage analysis approach using novel, highly informative microsatellite markers from the class III HLA region.  (+info)

Congenital adrenal hyperplasia: not really a zebra. (2/446)

Congenital adrenal hyperplasia was once considered a rare inherited disorder with severe manifestations. Mild congenital adrenal hyperplasia, however, is common, affecting one in 100 to 1,000 persons in the United States and frequently eluding diagnosis. Both classic and nonclassic forms of the disease are caused by deficiencies in the adrenal enzymes that are used to synthesize glucocorticoids. The net result is increased production from the adrenal gland of cortisol precursors and androgens. Even mild congenital adrenal hyperplasia can result in life-threatening sinus or pulmonary infections, orthostatic syncope, shortened stature and severe acne. Women with mild congenital adrenal hyperplasia often present with hirsutism, oligomenorrhea or infertility. Congenital adrenal hyperplasia is diagnosed by demonstration of excess cortisol precursors in the serum during an adrenal corticotropic hormone challenge. Diagnosis of congenital adrenal hyerplasia in fetuses that are at risk for congenital adrenal hyperplasia can be determined using human leukocyte antigen haplotype or by demonstration of excess cortisol precursors in amniotic fluid. Treatment includes carefully monitored hormone replacement therapy. Recognition of the problem and timely replacement therapy can reduce morbidity and enhance quality of life in patients that are affected by congenital adrenal hyperplasia.  (+info)

Tracing past population migrations: genealogy of steroid 21-hydroxylase (CYP21) gene mutations in Finland. (3/446)

The genealogic origin of steroid 21-hydroxylase gene (CYP21) mutations and associated haplotypes was determined in 74 unrelated Finnish families with CYP21 deficiency (congenital adrenal hyperplasia, CAH). These families account for two thirds (85/119) of all diagnosed patients of Finnish descent found in this country. We recently demonstrated that multiple founder mutations each associated with a particular haplotype can be found in Finland. Interestingly, some of the haplotypes were identical to those observed in various European populations, whereas others have not been described elsewhere, indicating a local and perhaps a more recent origin. In the present report we show that each of the major founder haplotypes originates from a particular geographic region of Finland. Thus many local genetic isolates are to be expected in Finland. Our finding is in a clear contrast to the genetic diseases known as the 'Finnish disease heritage', in which only one mutation usually predominates. Some of the CYP21 haplotypes proved very informative for analysis of the history of the Finnish population. For example, the origin of one frequent haplotype was shown to cluster in a region assumed by archaeological data to be a major site of immigration by settlers of either Scandinavian or Baltic origin during the first centuries AD. As this haplotype is frequent in many European patient populations, we provide independent genetic evidence of this Iron Age immigration. On the other hand, another frequent haplotype found solely in Finland reflects a more recent (post 15th century) settlement expansion. Consequently, well characterised and sufficiently frequent autosomal gene markers can provide useful information on migrations both between and within populations.  (+info)

Modular variations of the human major histocompatibility complex class III genes for serine/threonine kinase RP, complement component C4, steroid 21-hydroxylase CYP21, and tenascin TNX (the RCCX module). A mechanism for gene deletions and disease associations. (4/446)

The frequent variations of human complement component C4 gene size and gene numbers, plus the extensive polymorphism of the proteins, render C4 an excellent marker for major histocompatibility complex disease associations. As shown by definitive RFLPs, the tandemly arranged genes RP, C4, CYP21, and TNX are duplicated together as a discrete genetic unit termed the RCCX module. Duplications of the RCCX modules occurred by the addition of genomic fragments containing a long (L) or a short (S) C4 gene, a CYP21A or a CYP21B gene, and the gene fragments TNXA and RP2. Four major RCCX structures with bimodular L-L, bimodular L-S, monomodular L, and monomodular S are present in the Caucasian population. These modules are readily detectable by TaqI RFLPs. The RCCX modular variations appear to be a root cause for the acquisition of deleterious mutations from pseudogenes or gene segments in the RCCX to their corresponding functional genes. In a patient with congenital adrenal hyperplasia, we discovered a TNXB-TNXA recombinant with the deletion of RP2-C4B-CYP21B. Elucidation of the DNA sequence for the recombination breakpoint region and sequence analyses yielded definitive proof for an unequal crossover between TNXA from a bimodular chromosome and TNXB from a monomodular chromosome.  (+info)

Single-nucleotide polymorphisms in intron 2 of CYP21P: evidence for a higher rate of mutation at CpG dinucleotides in the functional steroid 21-hydroxylase gene and application to segregation analysis in congenital adrenal hyperplasia. (5/446)

BACKGROUND: Intron 2 of CYP21, the functional steroid 21-hydroxylase gene contains several single-nucleotide polymorphisms (SNPs). We tested the hypothesis that intron 2 of the pseudogene, CYP21P, might also be polymorphic and provide markers for segregation analysis of this region of the genome, including observable markers for segregation analysis of CYP21 gene deletions. A comparison of SNPs in both genes might provide insights into the rates of mutation in these duplicated genes. METHODS: After amplification with PCR, we examined restriction site polymorphisms in intron 2 of CYP21P in 24 members of the parental generation of the Centre d'Etude du Polymorphisme Humain families and selected offspring. RESULTS: Intron 2 of CYP21P contains frequent SNPs around nucleotide 398 and nucleotide 509, which can be typed by PCR/restriction enzyme digestion with HaeIII. Of the 48 CYP21P alleles examined, 44 could be characterized unambiguously. Of these 44 alleles, 4 were deleted, and the frequencies of restriction at the polymorphic HaeIII sites were 20 of 40 at nucleotide 398 and 30 of 40 at nucleotide 509. Both polymorphisms result from C-->T transitions that occur at CpG dinucleotides. The frequencies of C at these nucleotides in CYP21P are significantly higher than at the corresponding nucleotides in CYP21 of the same individuals (P <0.01). CONCLUSION: These data suggest that these CpG dinucleotides are more frequently mutated in CYP21 than in CYP21P, and that several mutations at CpG dinucleotides in the coding regions of CYP21 might result from CpG instability rather than the more usually proposed mechanism of gene conversion. These frequent SNPs provide useful markers for studying both allelic segregation of CYP21, particularly for chromosomes with known CYP21 deletions, and for investigating the origin of these polymorphisms.  (+info)

Mutation analysis in patients with congenital adrenal hyperplasia in the Spanish population: identification of putative novel steroid 21-hydroxylase deficiency alleles associated with the classic form of the disease. (6/446)

Steroid 21-hydroxylase deficiency, due to the genetic impairment of the CYP21 gene, is a major cause of congenital adrenal hyperplasia (CAH). In about 80% of the cases, the defect is related with the transfer of deleterious point mutations from the CYP21P pseudogene to the active CYP21 gene. Sixteen different point mutations have been searched for in 60 Spanish patients with the classic form of CAH and 171 unaffected family members, using selective amplification of the CYP21 gene followed by allele-specific oligonucleotide hybridization (PCR-ASOH) and sequencing analysis. While 31.9% of the disease alleles carry CYP21 deletions or large gene conversions, around 58% of the alleles carry single point mutations. Corresponding segregation of mutations was found in every case indicating that none of them has apparently appeared de novo. The most frequent mutations found in our sample are i2G, V281L, R356W, Q318X, P453S and F306+t, with rates of 30, 14.2, 10, 9.2, 9.2 and 7. 5%, respectively. We found similar frequencies for the A and C polymorphism at position 656 (40 and 31.5%, respectively) in wild-type alleles for the i2G mutation. Around 10% of the alleles, for which no mutations were identified by searching for the sixteen previously known mutations, are currently being sequenced and new possible mutations and polymorphisms have been identified.  (+info)

Fluorescent PCR and automated fragment analysis in preimplantation genetic diagnosis for 21-hydroxylase deficiency in congenital adrenal hyperplasia. (7/446)

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease which is most often caused by a deficiency in steroid 21-hydroxylase. The disease is characterized by a range of impaired adrenal cortisol and aldosterone synthesis combined with an increased androgen synthesis. These metabolic abnormalities lead to an inability to conserve sodium and virilization of females. The most common mutation causing the severe form of CAH is a conversion of an A or C at nucleotide (nt) 656 to a G in the second intron of the steroid 21-hydroxylase gene (CYP21) causing aberrant splicing of mRNA. A couple was referred to our centre for preimplantation genetic diagnosis (PGD) for 21-hydroxylase deficiency in CAH. A PGD was set up to detect the nt656 A/C-->G mutation using fluorescent polymerase chain reaction (PCR) and subsequent restriction enzyme digestion and fragment analysis on an automated sequencer. Using DNA or single cells from the father, the normal allele could not be amplified. Non-amplification of the normal allele has been previously described in asymptomatic carriers, therefore the PCR was further developed using heterozygous lymphoblasts from the mother. The PCR was shown to be highly efficient (96% amplification), accurate (0% contamination) and reliable (0% allelic drop-out). The couple started PGD treatment and the second PGD cycle resulted in a twin pregnancy. The genotype of the fetuses was determined in our laboratory using chorionic villus sampling material using the method described here. Both fetuses were shown to be heterozygous carriers of the mutation, and two healthy girls were born.  (+info)

Adrenomedullary function is severely impaired in 21-hydroxylase-deficient mice. (8/446)

Deficiency of 21-hydroxylase (21-OH), one of the most common genetic defects in humans, causes low glucocorticoid and mineralocorticoid production by the adrenal cortex, but the effect of this disorder on the adrenomedullary system is unknown. Therefore, we analyzed the development, structure, and function of the adrenal medulla in 21-OH-deficient mice, an animal model resembling human congenital adrenal hyperplasia. Chromaffin cells of 21-OH-deficient mice exhibited ultrastructural features of neuronal transdifferentiation with reduced granules, increased rough endoplasmic reticulum and small neurite outgrowth. Migration of chromaffin cells in the adrenal to form a central medulla was impaired. Expression of phenylethanolamine-N-methyltransferase (PNMT) was reduced to 27 +/- 9% (P<0.05), as determined by quantitative TaqMan polymerase chain reaction, and there was a significant reduction of cells staining positive for PNMT in the adrenal medulla of the 21-OH-deficient mice. Adrenal contents of epinephrine were decreased to 30 +/- 2% (P<0. 01) whereas norepinephrine and dopamine levels were reduced to 57 +/- 4% (P<0.01) and 50 +/- 9% (P<0.05), respectively. 21-OH-deficient mice demonstrate severe adrenomedullary dysfunction, with alterations in chromaffin cell migration, development, structure, and catecholamine synthesis. This hitherto unrecognized mechanism may contribute to the frequent clinical, mental, and therapeutic problems encountered in humans with this genetic disease.  (+info)

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OH CAH), in all its forms, accounts for over 95% of diagnosed cases of congenital adrenal hyperplasia, and CAH in most contexts refers to 21-hydroxylase deficiency. An overview of the other types of CAH is presented in the main article. The condition can be classified into salt-wasting, simple virilizing, and non-classical forms. The salt-wasting and simple virilizing types are sometimes grouped together as classical. The CYP21A2 gene for the P450c21 enzyme (also known as 21-hydroxylase) is at 6p21.3, amid genes HLA B and HLA DR coding for the major human histocompatibility loci (HLA). CYP21A2 is paired with a nonfunctional pseudogene CYP21A1P. Scores of abnormal alleles of CYP21A2 have been documented, most arising from recombinations of homologous regions of CYP21A2 and CYP21A1P. Differences in residual enzyme activity of the various alleles account for the various degrees of severity of the disease. Inheritance of ...
Congenital adrenal hyperplasia due to 11β-hydroxylase deficiency is a form of congenital adrenal hyperplasia (CAH) which produces a higher than normal amount of androgen, resulting from a defect in the gene encoding the enzyme steroid 11β-hydroxylase which mediates the final step of cortisol synthesis in the adrenal. 11β-OH CAH results in hypertension due to excessive mineralocorticoid effects. It also causes excessive androgen production both before and after birth and can virilize a genetically female fetus or a child of either sex. Mineralocorticoid manifestations of severe 11β-hydroxylase deficient CAH can be biphasic, changing from deficiency (salt-wasting) in early infancy to excess (hypertension) in childhood and adult life. Salt-wasting in early infancy does not occur in most cases of 11β-OH CAH but can occur because of impaired production of aldosterone aggravated by inefficiency of salt conservation in early infancy. When it occurs it resembles the salt-wasting of severe ...

This study was developed to determine if a combination of four drugs (flutamide, testolactone, reduced hydrocortisone dose, and fludrocortisone) can normalize growth in children with congenital adrenal hyperplasia.. The study will take 60 children, boys and girls and divide them into 2 groups based on the medications given. Group one will receive the new four- drug combination. Group two will receive the standard treatment for congenital adrenal hyperplasia (hydrocortisone and fludrocortisone).. The boys in group one will take the medication until the age of 14 at which time they will stop taking the four drug combination and begin receiving the standard treatment for congenital adrenal hyperplasia. Girls in group one will take the four drug combination until the age of 13, at which time they will stop and begin receiving the standard treatment for congenital adrenal hyperplasia plus flutamide. Flutamide will be given to the girls until six months after their first menstrual period.. All of the ...

Evaluation of Blood Pressure and Left Ventricular Parameters in Children with Classical Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency: An Egyptian Experience Abstract.
3. Androgens, which are responsible for the development of secondary sexual characteristics (adrenarche) in both males and females.. All three of these adrenal hormones are necessary for normal body functioning in both males and females. In patients with Congenital Adrenal Hyperplasia, the adrenal glands typically produce too little cortisol and aldosterone, while producing too much of the androgen hormones. Excess levels of androgens can cause atypical genitalia, growth abnormalities, early puberty, and problems with fertility. All infants born in the United States are screened for Congenital Adrenal Hyperplasia shortly after birth. If your child is diagnosed with Congenital Adrenal Hyperplasia, additional tests including blood tests and imaging tests, such as X-rays or ultrasounds, are often done. Ultimately, genetic testing is used to confirm the diagnosis.. CAH is a condition that requires long-term follow-up and monitoring. The treatment involves life-long cortisol with or without ...

Introduction: 21-Hydroxylase deficiency is the most frequent form of congenital adrenal hyperplasia (CAH) which is a common autosomal recessive disorder characterized by impaired adrenocortical and adrenomedullary function, and adrenal hyperandrogenism. Chronic glucocorticoid therapy and excess androgen exposure in patients with CAH may predispose them to developing a metabolic syndrome in adulthood.Our objective is to evaluate the metabolic syndrome in adulthood in a Tunisian cohort.. Subjects and Methods: We underwent a prospective study of 26 patients over 16 years of old with CAH.. Results: The cases included 26 patients (M: 11, F: 15) with CAH due to 21-hydroxylase deficiency with a mean age of 27.4 years (16.5-48 years). Eighteen patients had the classical CAH form and the remaining 8 patients had the non-classical form. The mean body mass index was 26,9 ± 4,27 kg/m2 (20,3-34,8 kg/m2). The most commonly used drug was hydrocortisone which was used by 21 cases. Five cases had been managed ...
There is no clear consensus among state newborn screening programs on whether routine second screening of newborns identifies clinically relevant cases of congenital adrenal hyperplasia. This retrospective study evaluated laboratory practices, along with biochemical and medical characteristics of congenital adrenal hyperplasia (CAH) cases (1) detected on the first newborn screen in one-screen compared to two-screen states, and (2) detected on the first versus the second screen in the two-screen states, to determine the effectiveness of a second screen. A total of 374 confirmed cases of CAH from 2 one-screen states and 5 two-screen states were included in this study. Demographic data and diagnostic information on each reported case were collected and analyzed. Additionally, laboratory data, including screening methodologies and algorithms, were evaluated. The one-screen states reported 99 cases of CAH out of 1,740,586 (1 in 17,500) newborns screened: 88 (89%) identified on the first screen and 5 ...

Classic congenital adrenal hyperplasia affects approximately 1 in 15,000 children. Current treatment strategies using multiple daily doses of hydrocortisone lead to suboptimal outcomes. We tested the hypothesis that nocturnal administration of dexamethasone will suppress the hypothalamic-pituitary-adrenal axis more effectively than standard hydrocortisone treatment by blocking the inherent diurnal secretion of ACTH. We performed a pilot study of five prepubertal patients comparing CAH control during two 24-hour hospitalizations, one on hydrocortisone and the other on dexamethasone. The patterns of adrenal suppression differed markedly between hydrocortisone and nocturnal dexamethasone, with significant suppression of the morning rise in ACTH, 17-hydroxyprogesterone, and androstenedione while on dexamethasone. On hydrocortisone therapy, there is a marked variation in ACTH and adrenal hormones depending on time of day and timing of hydrocortisone administration. Longer-term studies are needed to
CAH21 : Preferred screening test for congenital adrenal hyperplasia (CAH) that is caused by 21-hydroxylase deficiency   Part of a battery of tests to evaluate females with hirsutism or infertility, which can result from adult-onset CAH
CAH21 : The cause of congenital adrenal hyperplasia (CAH) is an inherited genetic defect that results in decreased formation of 1 of the many enzymes that are involved in the production of cortisol. The enzyme defect results in reduced glucocorticoids and mineralocorticoids, and elevated 17-hydroxyprogesterone (OHPG) and androgens. The resulting hormone imbalances can lead to life-threatening, salt-wasting crises in the newborn period and incorrect gender assignment of virilized females. Adult-onset CAH may result in hirsutism or infertility in females.   The adrenal glands, ovaries, testes, and placenta produce OHPG. It is hydroxylated at the 11 and 21 positions to produce cortisol. Deficiency of either 11- or 21-hydroxylase results in decreased cortisol synthesis, and the feedback inhibition of adrenocorticotropic hormone (ACTH) secretion is lost. Consequently, increased pituitary release of ACTH increases production of OHPG. In contrast, if 17-alpha-hydroxylase (which allows formation of OHPG
Treatment with glucocorticoids and mineralocorticoids has changed congenital adrenal hyperplasia (CAH) from a fatal to a chronic lifelong disease. Long-term treatment, in particular the chronic (over-)treatment with glucocorticoids, may have an adverse effect on the cardiovascular risk profile in adult CAH patients. The objective of this study was to evaluate the cardiovascular risk profile of adult CAH patients.. DESIGN: Case control study Primary objective : detection of cardiovascular damage in patients with classical or non classical CAH diagnosed in childhood. The patients will be compared with age- and gender- and tobacco status- matched control.. Secondary objective Study of microvascular function Evaluation of cardiovascular risk factors Total cumulative (TCG) and total average (TAG) glucocorticoid doses will be calculated from pediatric and adult files and correlated to arterial macro- and microcirculatory dysfunction.. Primary outcome Ultrasound evaluation of intima-media thickness at ...
there may be clinical and laboratory finding. The aim was to evaluate the epidemiology and clinical finding of CAH. The clinical and laboratory characteristics of 68 patients with CAH who were managed in the pediatric Endocrinology unit of Imam Reza Hospital during 7 years were recorded in this study; the clinical and epidemiological characteristics of congenital adrenal hyperplasia were evaluated in 68 patients admitted Imam Reza Hospital in Mashed, also one patient has been followed in endocrine and metabolism pediatric clinic in this time, during 6 years retrospectively and I year prospectively. Parental consanguinity rate among families of patients was higher than the general population in Mashad [73.8% vs 30%]. In 44.6% of patients the history of disease were positive in sibling.52.2% of patients were males and 47.8% females.21- Hydroxylase deficiency was present in 60 patients [88.2%], salt - losing form in 40 [66.7%] and simple virilizing form in 20 [33.3%] of them.11- beta hydroxylase ...
To determine the glucocorticoid receptor (GC-R) status in congenital adrenal hyperplasia (CAH) we examined 11 patients (5 female, 6 male) with 21-hydroxylase deficiency and 3 patients (2 female, 1 male) with 11 beta -hydroxylase deficiency, The mean age at investigation was 8.9+/-3.5 yr, Age of diagnosis was 4.4+/-3.2 yr and all patients were being treated with hydrocortisone, The control group included 10 (5 female, 5 male) age-matched healthy children. Blood samples were drawn at 0800 a.m. after an overnight fast in all subjects and after 5 days off treatment in patients with CAH. Serum cortisol tin all children), and serum 17-hydroxyprogesterone and androstenedione tin the patient group) were measured by radioimmunoassay, Mononuclear leukocytes were isolated from peripheral blood and the binding of [H-3]dexamethasone to GC-R was examined. GC-R number and the dissociation constant (Kd), which is inversely proportional to its binding affinity, were determined, Mean GC-R numbers were 5814+/-1574 ...
The majority of congenital adrenal hyperplasia (CAH) cases arise from mutations in the steroid 21-hydroxylase (CYP21) gene. Without reliance on HLA gene linkage analysis, we have developed primers for differential polymerase chain reaction (PCR) amplification of the CYP21 gene and the non-functional CYP21P gene. Using the amplification created restriction site (ACRS) approach for direct mutational detection, a secondary PCR was then performed using a panel of primers specific for each of the 11 known mutations associated with CAH. Subsequent restriction analysis allowed not only the detection but also the determination of the zygosity of the mutations analysed. Existing deletion of the CYP21 gene could also be detected. In the analysis of 20 independent chromosomes in 11 families of CAH patients in Taiwan, four CYP21 mutation types, besides deletion, were detected. Interestingly, in five different alleles, the CYP21P pseudogene contained some polymorphisms generally associated with the CYP21 ...
Congenital adrenal hyperplasia (CAH) is a disorder that affects the adrenal glands ability to release hormones that regulate the bodys response to stress and illness. CAH is treatable, but can be potentially life-threatening during illness or if not managed. The disorder is difficult to identify, and much still needs to be understood about the condition. But new research conducted at Childrens Hospital Los Angeles has shown that computers may be able to use subtle facial features to recognize CAH. This finding could lead to better identification of the disorder and better care of CAH patients. In endocrinology, CAH is one of the few emergency conditions we encounter, says Mimi Kim, MD, MSc, co-Director of the CAH Comprehensive Care Clinic at Childrens Hospital Los Angeles. Its the leading cause of adrenal insufficiency in children, which means the body cant produce aldosterone, adrenaline and cortisol.. These hormones allow the body to manage blood pressure and respond to crises. In ...
The clinical manifestations of CAH in adults result from adrenocortical and adrenomedullary insufficiency, hyperandrogenism, and the adverse effects of glucocorticosteroids used for the treatment of the condition. Non-classic CAH may sometimes be asymptomatic. In patients with classic CAH obesity, hyperinsulinaemia, insulin resistance, and hyperleptinaemia are more often seen than in the general population. These abnormalities promote the development of metabolic syndrome and its sequelae, including endothelial dysfunction, and cardiovascular disease. Long-term glucocorticosteroid treatment is also a known risk factor for osteoporosis ...

Congenital adrenal hyperplasia (CAH) is caused by the genetic impairment of one of the five enzymes required for the biosynthesis of cortisol from cholesterol. In 95% of cases 21-hydroxylase deficiency (21-OHD) is responsible for the disease (1). Classic 21-OHD has an incidence varying from 1:11 800 to 1:21 800, depending on the population background. The pathophysiology, clinical picture, genetics, and the unique aspects of management from the point of view of the paediatric endocrinologist are addressed, and the problems encountered from birth to puberty are described. The child specific issues of rare forms of CAH are summarized thereafter. The reader is referred to Chapter 5.11 for a comprehensive overview of 21-OHD and for more details on all other forms of CAH.. ...
Objective: Despite published guidelines no unified approach to hormone replacement in congenital adrenal hyperplasia (CAH) exists. We aimed to explore geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids in CAH. Design: This retrospective multi-center study, including 31 centers (16 countries), analyzed data from the International-CAH Registry. Methods: Data was collected from 461 patients aged 0-18 years with classic 21-hydroxylase deficiency (54.9% females) under follow-up between 1982 - 2018. Type, dose and timing of glucocorticoid and mineralocorticoid replacement was analyzed from 4174 patient visits. Results: The most frequently used glucocorticoid was hydrocortisone (87.6%). Overall, there were significant differences between age groups with regards to daily hydrocortisone-equivalent dose for body surface, with the lowest dose (median with interquartile range) of 12.0 (10.0 - 14.5) mg/ m2/ day at age 1 - 8 years and the highest dose of 14.0 ...
Meningioma growth has been previously described in patients receiving oestrogen/progestogen therapy. We describe the clinical, radiological, biochemical and pathologic findings in a 45-year-old woman with congenital adrenal hyperplasia secondary to a defect in the 21-hydroxylase enzyme who had chronic poor adherence to glucocorticoid therapy with consequent virilisation. The patient presented with a frontal headache and marked right-sided proptosis. Laboratory findings demonstrated androgen excess with a testosterone of 18.1 nmol/L (0-1.5 nmol) and 17-Hydroxyprogesterone ,180 nmol/L (,6.5 nmol/L). CT abdomen was performed as the patient complained of rapid-onset increasing abdominal girth and revealed bilateral large adrenal myelolipomata. MRI brain revealed a large meningioma involving the right sphenoid wing with anterior displacement of the right eye and associated bony destruction. Surgical debulking of the meningioma was performed and histology demonstrated a meningioma, which stained ...
Introduction: The diagnosis of Congenital Adrenal Hyperplasia (CAH) is a challenge due to the complexity of its pathophysiology and the variety of clinical manifestations. Female newborns (NB) with classical forms present virilization of the external genitalia while in boys it is usually normal. Salt-losers boys and girls are highly susceptible to develop acute adrenal insufficiency and death in the first weeks of life; for these reasons, Neonatal Screening (NS) programs have included CAH among the diseases surveyed. In the State of Parana, Brazil, NS for CAH started in 2013.. Objectives: To determine the prevalence of CAH in Parana; to characterize interfering factors related to false positive results for CAH; and to determine sensitivity, specificity, accuracy, positive and negative predictive values and false positive rate of the 17-OHP dosing method.. Patients and methods: Clinical and laboratorial evaluation of NB tested positive for CAH in the period of August/2013-July/2016; 17-OHP in ...
Congenital adrenal hyperplasia (CAH), also known as the adrenogenital syndrome, is an uncommon condition caused by a congenital defect in one of several enzymes that take part in the chain of reactions whereby cortisol is manufactured from its precursors. There are at least six fairly well-defined variants of CAH that result from the various enzyme defects. The most common of these are types I and II, which are due to C21-hydroxylase enzyme deficiency. All CAH variants are inherited as autosomal recessive traits. The clinical and laboratory findings depend on which metabolic pathway-and which precursor in the metabolic pathway- is affected. All variants affect the glucocorticoid (cortisol) pathway in some manner. In CAH due to 21-hydroxylase defect (types I and II) and in CAH type III, although formation of cortisone and cortisol is blocked, the precursors of these glucocorticoids are still being manufactured. Most of the early precursors of cortisone are estrogenic compounds, which also are ...
Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by defects in the steroid 21 hydroxylase gene (CYP21A2). We studied the spectrum of mutations in CYP21A2 gene in a multi-ethnic population in Pakistan to explore the genetics of CAH. A cross sectional study was conducted for the identification of mutations CYP21A2 and their phenotypic associations in CAH using ARMS-PCR assay. Overall, 29 patients were analyzed for nine different mutations. The group consisted of two major forms of CAH including 17 salt wasters and 12 simple virilizers. There were 14 phenotypic males and 15 females representing all the major ethnic groups of Pakistan. Parental consanguinity was reported in 65% cases and was equally distributed in the major ethnic groups. Among 58 chromosomes analyzed, mutations were identified in 45 (78.6%) chromosomes. The most frequent mutation was I2 splice (27%) followed by Ile173Asn (26%), Arg 357 Trp (19%), Gln319stop, 16% and Leu308InsT (12%), whereas Val282Leu
Congenital hyperplasia of the adrenal glands is a rare pathology, which can have an impact on male fertility. We report 2 cases of azoospermia in patients followed for a classical form of congenital adrenal hyperplasia. 1st case: After 18 months of infertility of the couple, explorations showed a high level of ACTH on the hormonal biological analysis. A therapeutic strategy combining hydrocortisone with dexamethasone induced a normal semen analysis, and the female partner of the patient subsequently had three spontaneous pregnancies. 2nd case: After two years of infertility of the couple, explorations showed adrenal testicular inclusions invading the 4/5th of the testis with a hypergonadotropic hypogonadism, the therapeutic reinforcement did not allow the improvement of semen analysis. Sertolian deficiency can be explained by: gonadotropic deficiency by excess of adrenal androgens and adrenal testicular lesions (risk of major spermatic alteration).

Congenital adrenal hyperplasia (CAH) is a problem that affects how the adrenal glands work. The adrenal glands need an enzyme to make certain hormones. Children with CAH are missing or have low levels of this enzyme.. The hormones produced by the adrenal glands affect nearly every organ in the body. They help the body cope with stress, hold salt and water, and maintain blood pressure. They also affect sexual development.. CAH is a problem that is passed through genes. Most of the time its found during routine newborn blood tests.. When a child has CAH, he or she will need to take medicine each day to replace the missing hormones.. You may have just learned that your baby has CAH. You will get more information and support from the hospital staff. ...
Congenital adrenal hyperplasia (CAH) is a genetic disorder caused by defective steroidogenesis that results in glucocorticoid deficiency; the most common underlying mutation is in the gene that encodes 21-hydroxylase. Life-saving glucocorticoid treatment was introduced in the 1950s, and the number of adult patients is now growing; however, no consensus has been reached on the management of CAH beyond childhood. Adult patients are prescribed a variety of glucocorticoids, including hydrocortisone, prednisone, prednisolone, dexamethasone and combinations of these drugs taken in either a circadian or reverse circadian regimen. Despite these personalized treatments, biochemical control of CAH is only achieved in approximately one-third of patients. Some patients have a poor health status, with an increased incidence of obesity and osteoporosis, and impaired fertility and quality of life. The majority of poor health outcomes seem to relate to inadequate treatment rather than the genotype of the patient.
Results: Predominant findings in females were incomplete pubertal development (four of five) and large ovarian cysts (five of five) prone to spontaneous rupture, in some only resolving after combined treatment with estrogen/progestin, GnRH superagonists, and glucocorticoids. Pubertal development in the two boys was more mildly affected, with some spontaneous progression. Urinary steroid profiling revealed combined CYP17A1 and CYP21A2 deficiencies indicative of ORD in all patients; all but one failed to mount an appropriate cortisol response to ACTH stimulation indicative of adrenal insufficiency. Diagnosis of ORD was confirmed by direct sequencing, demonstrating disease-causing POR mutations ...
Objective: Episodes of acute adrenal insufficiency (AI)/adrenal crises (AC) are a serious consequence of congenital adrenal hyperplasia (CAH). This study aimed to assess morbidity from acute illness in CAH and identify factors associated with use of IV hydrocortisone, admission and diagnosis of an AC. Method: An audit of acute illness presentations among children with CAH to paediatric hospitals in New South Wales, Australia, between 2000 and 2015. Results: There were 321 acute presentations among 75 children with CAH. Two‐thirds (66.7%, n = 214) of these resulted in admission and 49.2% (n = 158) of the patients received intravenous (IV) hydrocortisone. An AC was diagnosed in (9.0%). Prior to presentation, 64.2% (n = 206) had used oral stress dosing and 22.1% (n = 71) had been given intramuscular (IM) hydrocortisone. Vomiting was recorded in 61.1% (n = 196), 32.7% (n = 64) of whom had used IM hydrocortisone. Admission, AC diagnosis and use of stress dosing varied significantly between ...

Introduction: Patients with primary adrenal insufficiency (Addison s disease) and patients with congenital adrenal hyperplasia (CAH) still tend to receive more glucococorticoids than the normal endogenous production in healthy subjects. CAH patients start glucocorticoid treatment usually with diagnosis in their early childhood, whereas Addison s patients have a later onset of their disease and start of their treatment.. Objective: To compare patients with Addison s disease and CAH in regard to their bone mineral density (BMD), the duration of glucocorticoid therapy and the impact of glucocorticoid pharmacogenetics.. Design, setting and participants: In a cross-sectional study patients from one university endocrine outpatient clinic were included (84 patients with Addison s disease, 42 patients with CAH). Bone mineral density (BMD) was measured using DXA scan. Blood samples were analysed for bone markers and 24 h urinary samples were analyzed for bone resorption markers.. Results: Patients with ...

A few cases of CAH-associated adrenal myelolipoma have been reported previously with most of them caused by 21-OH deficiency. The second most common cause was 17-OH deficiency (11). In the current report, two patients in family 1 presented with CAH-associated giant adrenal myelolipomas secondary to 21-OH deficiency caused by a compound heterozygous mutation (c.293-13C,G/c.518T,A, p.I173N). Three patients in family 2 presented with CAH-associated adrenal myelolipomas because of 17-OH deficiency resulting from a compound heterozygous mutation (c.1118A,T, p.H373L/c.1459_1467del9, p.D487_F489del). All the four mutations have been reported to be associated with CAH, respectively (12, 13, 14, 15). However, no adrenal myelolipoma was found with single mutations. Here, we firstly described these two compound heterozygous mutations in two unrelated families and found that only these compound heterozygous mutations, but not the single mutation, in the CYP genes can result in adrenal myelolipomas..

This report suggests that early exfoliation of primary teeth can be a side effect of bone resorption in patients with CAH. Early exfoliation of the primary dentition and bone loss is an uncommon finding in children. However, whenever it occurs is important to diagnose the patient early because it is usually correlated with serious systematic diseases.18. Premature loss of primary teeth has not been reported in the past in a case of CAH. However, CAH should be included in the differential diagnosis of premature loss of teeth because disturbance in dental development may be the first symptom of this disorder.13 Other systematic diseases that may cause premature exfoliation of teeth include hypophosphatasia, aggressive periodontitis, Papillon-Lefèvre syndrome, Singleton-Merten syndrome, Hajdu-Cheney syndrome immunodeficiency (neutropenia, leukocyte adhesion deficiency, leukemia), Langerhans histocytosis, diabetes mellitus, hyperthyroidism, cherubism, dentinal dysplasia, Ehlers-Danlos syndrome, ...

A key question in understanding gender development concerns the origins of sex segregation. Childrens tendencies to interact with same-sex others have been hypothesized to result from gender identity and cognitions, behavioral compatibility, and personal characteristics. We examined whether prenatal androgen exposure was related to time spent with boys and girls, and how that gendered peer involvement was related to sex-typed activities and gender identity and cognitions. We studied 54 girls with congenital adrenal hyperplasia (CAH) aged 10-13 years varying in degree of prenatal androgen exposure: 40 girls with classical CAH (C-CAH) exposed to high prenatal androgens and 14 girls with non-classical CAH (NC-CAH) exposed to low, female-typical, prenatal androgens ...

Common genetic variants at the ARL15 locus are associated with plasma adiponectin, insulin and HDL cholesterol concentrations, obesity, and coronary atherosclerosis. The ARL15 gene encodes a small GTP-binding protein whose function is currently unknown. In this study adipocyte-autonomous roles for ARL15 were investigated using conditional knockdown of Arl15 in murine 3T3-L1 (pre)adipocytes. Arl15 knockdown in differentiated adipocytes impaired adiponectin secretion but not adipsin secretion or insulin action, while in preadipocytes it impaired adipogenesis. In differentiated adipocytes GFP-tagged ARL15 localized predominantly to the Golgi with lower levels detected at the plasma membrane and intracellular vesicles, suggesting involvement in intracellular trafficking. Sequencing of ARL15 in 375 severely insulin resistant patients identified four rare heterozygous variants, including an early nonsense mutation in a proband with femorogluteal lipodystrophy and non classical congenital adrenal ...
XX Intersex: Refers to people born with female chromosomes and ovaries, but external genitalia that appears male. The labia fuse, and the clitoris enlarges to sometimes look like a penis. It is most commonly caused by a condition called congenital adrenal hyperplasia, or CAH. This condition is how I got involved and interested in the identity of intersex. My sister has one of the variants of CAH, and I am a carrier for this disease. This means that should I one day have biological children, my children have an increased chance of being born with it, thus increasing their likelihood of being intersex. CAH refers to inherited disorders of the adrenal glands. These make hormones like cortisol and aldosterone, which are super important for life. People with CAH lack an enzyme that is necessary to make these essential hormones. So, the body produces more and more androgen (a male sex hormone), which causes male characteristics to either start super early, such as super premature puberty in boys, or ...
Disordered steroidogenesis due to cytochrome P450 oxidoreductase deficiency (DISPORD) [MIM:613571]: A disorder resulting in a rare variant of congenital adrenal hyperplasia, with apparent combined P450C17 and P450C21 deficiency and accumulation of steroid metabolites. Affected girls are born with ambiguous genitalia, but their circulating androgens are low and virilization does not progress. Conversely, affected boys are sometimes born undermasculinized. Boys and girls can present with bone malformations, in some cases resembling the pattern seen in patients with Antley-Bixler syndrome. {ECO:0000269,PubMed:14758361, ECO:0000269,PubMed:15220035}.

About Adrenal Insufficiency Adrenal insufficiency (AI) is a condition characterised by deficiency in cortisol, an essential hormone in regulating metabolism and the response to stress. The primary symptoms of AI are chronic fatigue and patients are at risk of adrenal crisis and death if they do not have adequate cortisol replacement. AI is either primary or secondary, with primary AI resulting from diseases intrinsic to the adrenal gland and secondary AI resulting from pituitary diseases where there is a failure of stimulation of the adrenal by the pituitary of the signalling hormone ACTH (adrenocorticotropic hormone). AI is estimated to affect over four million patients globally.. In the paediatric setting, AI, including the related genetic condition congenital adrenal hyperplasia, is estimated to affect approximately 400 patients in Australia and New Zealand. In Europe, AI has been identified as a rare condition, where there are estimated to be approximately 4,000 sufferers younger than the ...
Cushings syndrome occurs when there is increase in cortisol hormone in the body due to stress. Adrenal glands are responsible for releasing cortisol to manage stress and emotions. Cortisol is taken in the form of medicine by some women. This increase in hormone will interfere with the normal secretion of sex hormone resulting in hirsutism. Tumor on the ovary, intake of certain drugs like danazol and congenital adrenal hyperplasia can cause excess of hair growth on cheeks and face areas in women. ...

Routine biochemistry should be performed, since hyponatraemia and hyperkalaemia may be present. In addition to this there may be hypoglycaemia, and a metabolic acidosis.. The hormonal findings depend on the enzyme affected. Cortisol and aldosterone are low or absent in nearly all subtypes; where the cortisol is low the serum ACTH will be raised as a normal physiological response. Also raised will be the substrate normally acted upon by the enzyme, thus 17-hydroxyprogesterone in 21-alpha-hydroxylase deficiency, 11-deoxycortisol in 11-beta-hydroxylase deficiency.. In addition to this there will be a raised level of products from pathways not affected by the deficiency; thus urinary pregnanetriol and 17-oxosteroids are elevated in the two defects mentioned above.. Chromosomal analysis is indicated if there is cryptorchidism.. Last reviewed 04/2021 ...

I just learned that I was born without left lobe of thyroid after years of constant fatigue and pain i was told by the same doctor for years that my thyroid was fine. I was stupid and never ask for the tests. They only ran TSH and has long as 7 years ago I was below normal .29 or bordeline and never had a T3 or T4done. Had several images of neck due to DDD but never mentioned my thyroid. Was told last CT was normal so went to another doctor and had the CT pulled. Says apparent post ressection rt lobe changes. Trying to get hold of radiologist had he meant by changes. Finally found one ct at a hospital and am trying to get it from 5 years ago. When I got my chart from doctor all reports were pulled My neck has been swelling all month, triangle lymph nodes around jugular and enlarged under jaw.
