21 Hydroxylase Deficiency

We describe a unique case of diagnosing salt-wasting congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency in a 32-year-old male patient. Before establishing the diagnosis, the main patient complaint was infertility. In childhood, the patient suffered from developmental delay, often illness, overconsumption of salt, and often vomiting; he stopped growing at the age of 12 years. In the adolescent period, his physical condition improved. Later, the patient got married, but was infertile. Plasma steroid profiling by gas chromatography-mass spectrometry (GC-MS) revealed markedly increased levels of 17-hydroxyprogesterone and 21-deoxycortisol and a decreased cortisol level, which enabled the diagnosis of CAH and 21-hydroxylase deficiency. The diagnosis was confirmed by a molecular genetic study that detected a CYP21 gene mutation — l2 splice in the homo(hemi)zygotic state, which was characteristic of the salt-wasting form of CAH. Also, the patient had secondary adrenal cortical adenoma caused by prolonged ACTH hyperstimulation and secondary hypogonadism associated with excessive production of adrenal androgens, which led to elevated levels of estrogens inhibiting production of LH and FSH. Treatment of the patient with glucocorticoids and mineralocorticoids and then with androgens improved his clinical condition and hormonal parameters.

21 Hydroxylase Deficiency

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is an autosomal recessive disorder of the adrenal cortex characterized by impairment of cortisol biosynthesis (with possible impairment of aldosterone biosynthesis) and excessive pituitary ACTH release, which promotes oversecretion of intact pathways products: 17-hydroxyprogesterone (17OHP), progesterone, and adrenal androgens androstendione and testosterone. 21-hydroxylase deficiency, being the most common cause of congenital adrenal hyperplasia is a chronic disorder, that requires life-long glucocorticoid treatment, that aims both to replace cortisol and prevent ACTH-driven androgen excess. Nevertheless, reaching the optimal glucocorticoid dose is challenging because currently available glucocorticoid formulations cannot replicate the physiological circadian rhythm of cortisol secretion. The difficulties in striking the balance between uneffective normalizing of ACTH-level and excess glucocorticoid exposure leads to different abnormalities, that starts to develop at first months of life and progress, frequently gaining especial clinical meaning in adult age. In the present clinical case we introduce 35 years old male patient with salt-wasting form of 21-hydroxylase deficiency, which had either complications considered to progress due to insufficient glucocorticoid therapy, and some metabolic abnormalities, associated with supraphysiological doses of glucocorticoids.

Congenital adrenal hyperplasia (CAH) is a group of inherited defects of cortisol biosynthesis. A case of classical CAH due to 21-hydroxylase deficiency (21-OHD) with early onset of salt waste and concurrence of meningomyelocele (MMC) was presented here. The management of salt-wasting crisis which is complicated by a postrenal dysfunction due to neurogenic bladder was described. Possible reasons of growth retardation in the one-year follow-up period were discussed. A significant regression of the phallus with proper medical treatment was also mentioned.

AbstractCongenital adrenal hyperplasia (CAH) due to steroid 21-hydroxylase deficiency represents a group of autosomal recessive disorders characterized by impaired cortisol production due to altered upstream steroid conversions, subclassified as classic and nonclassic forms. The genotype–phenotype correlation is possible in the most frequent case but not in all. Despite in literature many mutations are known, there is the possibility of finding a new genetic pattern in patients with CAH.

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

Abstract Context Women with congenital adrenal hyperplasia (CAH) may present with androgen excess that is difficult to control with conventional suppressive doses of glucocorticoids. Clinical management is challenging, and the woman is at great risk of developing steroid-induced complications. Patients and Methods A 32-year-old woman with salt-wasting CAH due to 21-hydroxylase deficiency underwent right-sided adrenalectomy because of a large myelolipoma. Over the years, androgens became increasingly difficult to suppress on prednisolone 5 + 0 + 2.5 mg daily, and at age 39 years the left adrenal with an enlarging myelolipoma was removed. A month later serum testosterone levels had increased from 4.1 preoperatively to 18.3 nmol/L (reference 0.2-1.8 nmol/L), and adrenocorticotropin levels from 32 to 283 pmol/L (reference < 14 pmol/L). No adrenal parenchyma was visualized on computed tomography (CT). In the further search for the source of the markedly elevated testosterone, positron emission tomography (PET) was performed with 2 different tracers, 18fluorodeoxyglucose (18FDG) reflecting glucose metabolism and 11C-metomidate, an inhibitor of 11-β-hydroxylase targeting adrenocortical tissue. Results 18FDG-PET/CT with cosyntropin stimulation showed ovarian/paraovarian hypermetabolism, suggestive of adrenal rest tumors. Further characterization with 11C-metomidate PET/CT showed uptakes localized to the ovaries/adnexa, behind the spleen, and between the right crus diaphragmaticus and inferior vena cava. Conclusion Adrenal rest tumors can give rise to high androgen levels in spite of suppressive supraphysiological glucocorticoid doses. This case illustrates, for the first time, the value of 11C-metomidate PET as a sensitive method in documenting adrenal rest tumors, currently considered rare in women with CAH.

21 Hydroxylase Deficiency

Abstract More than 90% of cases of congenital adrenal hyperplasia (CAH, the inherited inability to synthesize cortisol) are caused by 21-hydroxylase deficiency. Females with severe, classic 21-hydroxylase deficiency are exposed to excess androgens prenatally and are born with virilized external genitalia. Most patients cannot synthesize sufficient aldosterone to maintain sodium balance and may develop potentially fatal “salt wasting” crises if not treated. The disease is caused by mutations in the CYP21 gene encoding the steroid 21-hydroxylase enzyme. More than 90% of these mutations result from intergenic recombinations between CYP21 and the closely linked CYP21P pseudogene. Approximately 20% are gene deletions due to unequal crossing over during meiosis, whereas the remainder are gene conversions—transfers to CYP21 of deleterious mutations normally present in CYP21P. The degree to which each mutation compromises enzymatic activity is strongly correlated with the clinical severity of the disease in patients carrying it. Prenatal diagnosis by direct mutation detection permits prenatal treatment of affected females to minimize genital virilization. Neonatal screening by hormonal methods identifies affected children before salt wasting crises develop, reducing mortality from this condition. Glucocorticoid and mineralocorticoid replacement are the mainstays of treatment, but more rational dosing and additional therapies are being developed.

Premature Pubarche

Abstract Classical 3β-hydroxysteroid dehydrogenase (3β-HSD) deficiency is a rare cause of congenital adrenal hyperplasia. We report two sisters presenting with delayed diagnoses of classical 3β-HSD, despite salt wasting (SW) episodes in infancy. Sibling 1 was referred for premature pubarche, slight growth acceleration, and advanced bone age, whereas sibling 2 had no signs of virilization. At referral, increased 17α-hydroxyprogesterone associated with premature pubarche at first suggested a nonclassical 21-hydroxylase deficiency. Sequencing of the CYP21 gene showed both girls only heterozygotes (V281L mutation). This result, combined with SW in infancy, suggested a 3β-HSD deficiency because of increased dehydroepiandrosterone sulfate levels. Further hormonal studies showed markedly elevated Δ5-steroids, in particular 17α-hydroxypregnenolone greater than 100 nmol/liter (the clue to the diagnosis) and elevated Δ5-/Δ4-steroid ratios. Sequencing of the type II 3β-HSD gene documented that both girls were compound heterozygotes for T181I and 1105delA mutations. Retrospectively, elevated levels of 17α-hydroxyprogesterone were found on blood spots from Guthrie’s test. There is no previous report of the combination of SW and premature pubarche due to mutations in the type II 3β-HSD gene. Because neonatal diagnosis could have prevented life-threatening crises in these girls, this report further supports the benefits for neonatal screening for congenital adrenal hyperplasia whatever the etiology.

21 Hydroxylase Deficiency

A direct, rapid and highly specific fluoroimmunoassay for determining serum levels of 17-hydroxyprogesterone has been developed. It is based on the use of a sheep antiserum covalently coupled to magnetisable particles and fluorescein-labelled steroid. Sodium salicylate is employed to eliminate interference from endogenous binding proteins in serum. The sensitivity of 0·5 nmol/L is adequate for clinical purposes. Analytical recovery, linearity and precision are satisfactory and the results obtained correlate closely with those of an established radioimmunoassay using 3H-labelled steroid and the same antiserum after initial sample extraction and chromatography. The values found for serum from normal adult subjects ranged from 1·0 to 12·6 nmol/L while those from treated and untreated patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency were 1·5 to 190 and 28·0 to 655 nmol/L, respectively.
