[PMID: 26594092 PMCID: PMC4639531 DOI: 10.1297/cpe.24.77] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2015] [Accepted: 03/10/2015] [Indexed: 11/07/2022] Open
Abstract
Purpose of developing the guidelines: The first guidelines for diagnosis and treatment of
21-hydroxylase deficiency (21-OHD) were published as a diagnostic handbook in Japan in
1989, with a focus on patients with severe disease. The “Guidelines for Treatment of
Congenital Adrenal Hyperplasia (21-Hydroxylase Deficiency) Found in Neonatal Mass
Screening (1999 revision)” published in 1999 were revised to include 21-OHD patients with
very mild or no clinical symptoms. Accumulation of cases and experience has subsequently
improved diagnosis and treatment of the disease. Based on these findings, the Mass
Screening Committee of the Japanese Society for Pediatric Endocrinology further revised
the guidelines for diagnosis and treatment. Target disease/conditions: 21-hydroxylase
deficiency. Users of the guidelines: Physician specialists in pediatric endocrinology,
pediatric specialists, referring pediatric practitioners, general physicians; and
patients.

Abstract
Steroid 21-hydroxylase deficiency (21-OHD) accounts for more than 90% of congenital adrenal hyperplasia. CAH newborn screening, in general, is based on 17-hydroxyprogesterone dosage (17-OHP), however it is complicated by the fact that healthy preterm infants have high levels of 17-OHP resulting in false positive cases. We report on molecular features of a boy born pre-term (GA = 30 weeks; weight = 1,390 g) with elevated levels of 17-OHP (91.2 nmol/L, normal < 40) upon neonatal screening who was treated as having CAH up to the age of 8 months. He was brought to us for molecular diagnosis. Medication was gradually suspended and serum 17-OHP dosages mantained normal. The p.V281L mutation was found in compound heterozygous status with a group of nucleotide alterations located at the 3' end intron 4 and 5' end exon 5 corresponding to the splice site acceptor region. Molecular studies continued in order to exclude the possibility of a nonclassical 21-OHD form. The group of three nucleotide changes was demonstrated to be a normal variant since they failed to interfere with the normal splicing process upon minigene studies.

Abstract
BACKGROUND Neonatal screening programs for congenital adrenal hyperplasia (21-CAH) using an immunoassay for 17alpha-hydroxyprogesterone (17-OHP) generate a high rate of positive results attributable to physiological reasons and to cross-reactions with steroids other than 17alpha-OHP, especially in preterm neonates and in critically ill newborns. METHODS To increase the specificity of the screening process, we applied a liquid chromatography-tandem mass spectrometry method quantifying 17alpha-OHP, 11-deoxycortisol, 21-deoxycortisol, cortisol, and androstenedione. The steroids were eluted in aqueous solution containing d8-17alpha-OHP and d2-cortisol and quantified in multiple reaction mode. RESULTS Detection limit was below 1 nmol/liter, and recovery ranged from 64% (androstenedione) to 83% (cortisol). Linearity was proven within a range of 5-100 nmol/liter (cortisol, 12.5-200 nmol/liter), and total run time was 6 min. Retrospective analysis of 6151 blood samples and 50 blood samples from newborns with clinically confirmed 21-CAH, as well as prospective analysis of 1609 samples of a total of 242,500 testing positive in our routine 17-OHP immunoassay, allowed clear distinction of affected and nonaffected newborns. High levels of 21-deoxycortisol were only found in children with 21-hydroxylase deficiency. Calculating the ratio of 17alpha-OHP to 21-deoxycortisol divided by cortisol further increased the sensitivity of the method. CONCLUSION Our liquid chromatography-tandem mass spectrometry procedure as a second-tier test can be used to reduce false-positive results of standard 21-CAH screening. The short total run time of 6 min allows for immediate reanalysis of all immunoassay results above the cutoff.

Abstract
A normal gonadal maturation with normal fertility are some of the major goals of long-term replacement therapy in adult males with Congenital Adrenal Hyperplasia (CAH). We describe here two young men, G.O. (case A, 23 years old) and S.S.(case B, 24 years old), both with a well defined diagnosis of CAH due to 21-hydroxylase deficiency classic homozygote form (21-CAH). In case A the diagnosis of the 21-CAH classic virilizing form was made at 3 years of age. The patient has undergone glucocorticoid therapy and is now 170 cm tall; all his hormonal findings are within the normal range. The semen analysis has shown a good fertility potential, with a slight modification when the patient decided to discontinue the therapy. In case B the diagnosis of the 21-CAH salt wasting form was performed at 9 days of age. The patient was initially treated with i.v. normal saline solution and a daily i.m. injection of hydrocortisone and, subsequently, with mineral and glucocorticoid replacement therapy po. A satisfactory adult stature (165 cm) was attained. The patient is still on therapy, with a good hormonal profile. The semen analysis has shown an apparently normal fertility. In conclusion, our experience in adult males with 21-CAH, who have been administered prompt and adequate replacement therapy, shows that these patients can attain normal quality of life, satisfactory growth and development, normal sexual maturation and activity, and adequate sperm fertilizing ability, thereby supporting the usefulness of continuing this therapy during adult age.

Abstract
OBJECTIVE To investigate the presence of a dysregulation in steroid biosynthesis in women from southern Italy. DESIGN Controlled clinical study. SETTING Normal and hyperandrogenic women referred to the Endocrinology Unit of Federico II University Medical School of Naples. PATIENT(S) One hundred fifty untreated young hyperandrogenic women and 50 normal age-matched women. INTERVENTION(S) Morning (basal) blood samples obtained in the early follicular phase and after a long (360 minute) ACTH stimulation test. MAIN OUTCOME MEASURE(S) The adrenal maximal response was calculated as stimulus under curve areas (AUCa), and all steroids were assayed using RIA methods. RESULT(S) A dysregulation of 21-hydroxylase was found in 22 patients (14.7%), with a prevalent increase of 17 alpha-hydroxyprogesterone AUC, whereas in 9 hirsute women (6%), there was a prevalent significant increase in 11-deoxycortisol AUC. In 5 women (3.3%), DHEA and DHEAS basal and AUCs plasma levels were increased, suggesting an impaired 3 beta-olo-dehydrogenase activity. The remaining 114 hyperandrogenic women (76%) compose the nonadrenal group, with a probable diagnosis of primitive functional ovarian hyperandrogenism. CONCLUSION(S) Considering the high prevalence of hirsutism and oligomenorrhea in our female hyperandrogenic population, we suggest an adrenal hyperresponsiveness likely due to a dysregulation in enzymes related to androgen adrenal steroidogenesis.

Abstract
All major classes of biologically active steroid hormones (progestins, mineralocorticoids, glucocorticoids, and sex steroids) are synthesized from cholesterol through 11 different bioconversions. With the exception of 5 alpha-reductase, all the enzymes mediating these reactions fall into two classes, cytochromes P450 and short-chain dehydrogenases. Cytochromes P450 are heme-containing membrane-bound proteins with molecular weights of approximately 50,000 that utilize molecular oxygen and electrons from NADPH-dependent accessory proteins to hydroxylate substrates. Short-chain dehydrogenases have molecular weights of 30,000-40,000, have tyrosine and lysine residues at the active site, and remove a hydride from the substrate, transferring the electrons of the hydride to NAD+ or NADP+. In most cases, this reaction is reversible so that the dehydrogenase can also function as a reductase under appropriate conditions. Inherited disorders in enzymes required for steroid biosynthesis have varying effects. Defects that prevent cortisol from being synthesized are referred to collectively as congenital adrenal hyperplasia. Because the enzymes required for cortisol biosynthesis in the adrenal cortex are in many cases required for the synthesis of mineralocorticoids and/or sex steroids, these classes of steroids may also not be synthesized normally. Thus, cholesterol desmolase and 3 beta-hydroxysteroid dehydrogenase deficiencies affect synthesis of all classes of steroids in both the adrenals and gonads. Steroid 21-hydroxylase deficiency, the most common cause (> 90% of cases) of congenital adrenal hyperplasia, can affect both mineralocorticoid and glucocorticoid synthesis, but androgen secretion is usually abnormally high due to shunting of accumulated precursors into this pathway. Excessive secretion of androgens and mineralocorticoids occurs in 11 beta-hydroxylase deficiency (the second most frequent form of congenital adrenal hyperplasia). Mineralocorticoid excess is also seen in 17 alpha-hydroxylase deficiency, but in this disorder sex steroid synthesis is defective. All defects that affect estrogen synthesis (deficiencies of cholesterol desmolase, 3 beta-hydroxysteroid dehydrogenase, 17 alpha-hydroxylase, aromatase, and 17 beta-hydroxysteroid dehydrogenase) are very rare, suggesting that the inability to synthesize placental estrogens may adversely affect fetal survival. A number of enzymes are expressed at sites of steroid action and regulate the amount of active steroid available to steroid receptors. Steroid 5 alpha-reductase converts testosterone to the more active dihydrotestosterone. Deficiency of this activity leads to incomplete development of male genitalia; 17 beta-hydroxysteroid dehydrogenase deficiency has similar phenotypic effects.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
HLA haplotypes, complement C4 factor and factor B immunochemical concentrations and autoantibodies titer have been studied in six patients with mild congenital adrenal hyperplasia (MC-AH), in two patients with classical congenital adrenal hyperplasia (CCAH) and in their parents. A high frequency of DR5 and C4BQO alleles have been found in MCAH patients. Moreover, C4BQO allele is carried out in three out of four cases associated with DR5. In the two CCAH patients we found a B51 and a B14 allele, the last one usually described in the non classical form of the disease in population of different ethnic origin. Signs of autoimmunity in some patients and parents have been found. C4 null alleles were several-fold more frequent among our patients with respect to the same ethnic control group and the autoantibody positivity could be the result of an altered immune regulation. The presence of a positive correlation between cortisol basal levels and C4 and Bf concentrations in the six MC-AH patients suggests an interrelationship between hormonal factors and immunological findings in this disease. Our finding about HLA antigens not previously described in this syndrome may stimulate more profound studies by genomic and cDNA probes.
