Abstract
BACKGROUND The most common cause of primary adrenal failure (Addison's disease) in the Western world is autoimmunity characterized by autoantibodies against the steroidogenic enzyme 21-hydroxylase (CYP21A2, 21OH). Detection of 21OH-autoantibodies is currently used for aetiological diagnosis, but how levels of 21OH-autoantibodies vary over time is not known. SETTING Samples from the national Norwegian Addison's Registry and Biobank established in 1996 (n = 711). Multi-parameter modelling of the course of 21OH-autoantibody indices over time. RESULTS 21OH-autoantibody positivity is remarkably stable, and >90% of the patients are still positive 30 years after diagnosis. Even though the antibody levels decline with disease duration, it is only rarely that this downturn reaches negativity. 21OH-autoantibody indices are affected by age at diagnosis, sex, type of Addison's disease (isolated vs autoimmune polyendocrine syndrome type I or II) and HLA genotype. CONCLUSION 21OH-autoantibodies are reliable and robust markers for autoimmune Addison's disease, linked to HLA risk genotype. However, a negative test in patients with long disease duration does not exclude autoimmune aetiology.

Abstract
Congenital Adrenal Hyperplasia is a group of autosomal recessive disorders due to deficiencies of enzymes involved in steroidogenesis. The most common form is a 21-hydroxylase deficiency which can be classical or non-classical. The severe form also called Classical Congenital Adrenal Hyperplasia is usually detected after birth to infant period. If Congenital Adrenal Hyperplasia is not diagnosed and treated early, neonates are susceptible to sudden death in the early weeks of life. We report a case of thirty-five days male with a salt-wasting variant of congenital adrenal hyperplasia. The diagnosis was based on an elevated level of 17-hydroxyprogesterone. He was managed and life long oral Prednisolone and Fludrocortisone were prescribed.

Abstract
Background In the nonclassical form (NC), good correlation has been observed between genotypes and 17OH-progesterone (17-OHP) levels. However, this correlation was not identified with regard to the severity of hyperandrogenic manifestations, which could depend on interindividual variability in peripheral androgen sensitivity. Androgen action is modulated by the polymorphic CAG tract (nCAG) of the androgen receptor (AR) gene and by polymorphisms in 5α-reductase type 2 (SRD5A2) enzyme, both of which are involved in the severity of hyperandrogenic disorders. Objectives To analyze whether nCAG-AR and SRD5A2 polymorphisms influence the severity of the nonclassical phenotype. Patients NC patients (n = 114) diagnosed by stimulated-17OHP ≥10 ng/mL were divided into groups according to the beginning of hyperandrogenic manifestations (pediatric and adolescent/adult) and CYP21A2 genotypes (C/C: homozygosis for mild mutations; A/C: compound heterozygosis for severe/mild mutations). Methods CYP21A2 mutations were screened by allelic-specific PCR, MLPA and/or sequencing. HpaII-digested and HpaII-undigested DNA samples underwent GeneScan analysis to study nCAG, and the SRD5A2 polymorphisms were screened by RLFP. Results Mean nCAG did not differ among pediatric, adolescent/adult and asymptomatic subjects. In the C/C genotype, we observed a significantly lower frequency of longer CAG alleles in pediatric patients than in adolescent/adults (p = 0.01). In patients carrying the A/C genotype, the frequencies of shorter and longer CAG alleles did not differ between pediatric patients and adolescent/adults (p>0.05). Patients with clitoromegaly had significantly lower weighted CAG biallelic mean than those without it: 19.1±2.7 and 21.6±2.5, respectively (p = 0.007), independent of the CYP21A2 genotype's severity. The SRD5A2 polymorphisms were not associated with the variability of hyperandrogenic NC phenotypes. Conclusions In this series, we observed a modulatory effect of the CAG-AR tract on clinical manifestations of the NC form. Although the NC form is a monogenic disorder, our preliminary data suggested that the interindividual variability of the hyperandrogenic phenotype could arise from polygenic interactions.

Abstract
There is a strong correlation between the severity of genotypes and 17OH-progesterone levels in patients with the nonclassical form of 21-hydroxylase deficiency (NC-CAH); however, there are few studies regarding the correlation with clinical signs. The aim of the study was to evaluate whether genotypes correlate with the severity of the hyperandrogenic phenotype. A cohort of 114 NC-CAH patients were diagnosed by stimulated-17OHP ≥10 ng/ml. CYP21A2 genotypes were divided into 2 groups according to the severity of enzymatic impairment; mild and severe. Clinical data and hormonal profiles were compared between the 2 groups. Age at onset of manifestations did not differ between children or adults carrying both mild and severe genotypes. Frequencies of precocious pubarche and hirsutism, with or without menstrual abnormalities, were similar between the 2 groups. There were no differences in basal testosterone levels of adult symptomatic females carrying both genotypes, but there were differences between adult females with (92.9±49.5 ng/dl) and without hirsutism (43.8±38 ng/dl) (p=0.0002). Similar frequencies of both genotypes were observed in asymptomatic females and in those with clitoromegaly. Nonclassical genotypes do not predict the severity of phenotype. Asymptomatic and virilized females carrying the same genotype suggest that there is a modulatory effect of genes involved in the androgen pathway on the phenotype.

Abstract
Children with 21-hydroxylase deficiency (21-OHD) need chronic glucocorticoid (cGC) therapy to replace congenital deficit of cortisol synthesis, and this therapy is the most frequent and severe form of drug-induced osteoporosis. In this study, we enrolled 18 patients (9 females) and 18 sex- and age-matched controls. We found in 21-OHD patients high serum and leukocyte levels of dickkopf-1 (DKK1), a secreted antagonist of the Wnt/β-catenin signaling pathway known to be a key regulator of bone mass. In particular, we demonstrated by flow cytometry, confocal microscopy, and real-time PCR that monocytes, T lymphocytes, and neutrophils from patients expressed high levels of DKK1, which may be related to the cGC therapy. In fact, we showed that dexamethasone treatment markedly induced the expression of DKK1 in a dose- and time-dependent manner in leukocytes. The serum from patients containing elevated levels of DKK1 can directly inhibit in vitro osteoblast differentiation and receptor activator of NF-κB ligand (RANKL) expression. We also found a correlation between both DKK1 and RANKL or COOH-terminal telopeptides of type I collagen (CTX) serum levels in 21-OHD patients on cGC treatment. Our data indicated that DKK1, produced by leukocytes, may contribute to the alteration of bone remodeling in 21-OHD patients on cGC treatment.

Abstract
OBJECTIVE To assess the utility of serum steroids measurement in monitoring the treatment of children with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD). METHOD Nineteen Patients with CAH 21OHD aged (3.67±1.54) years treated with hydrocortisone and fluorocortisone replacement were followed up at an intervals of 0.33 - 1.0 years over a period of (1.47±0.7) years. At each visit, roentgenograms of the hands and wrists were taken, fasting peripheral blood were collected to test serum dehydroepiandrosterone sulfate, progesterone, 17-hydroxyprogesterone (17-OHP), androstenedione (Δ4-A), testosterone, free testosterone, estrone, and estradiol concentrations at 8 AM in the morning before the first dose of glucocorticoid. Then the patients were classified as being in "Good Control" or in "Poor Control" based on clinical criteria including signs of androgen excess, growth velocity and bone age increment at each interval. Comparisons were carried out between the serum steroid concentrations of the two groups. The receiver operating characteristic (ROC) curves were used to determine the cut-off values for diagnosing "Poor Control". RESULT Both of serum Δ4-A and 17-OHP concentrations were higher in "Poor Control" group than those in "Good Control" group [5.95 (2.23-11.2) nmol/L versus 1.05 (1.05-9.89) nmol/L, t=2.19; 13.85 (6.06-20) µg/L versus 3.67 (0.42-21.1) µg/L, t=2.17; P<0.05, respectively]. The ROC curves for serum Δ4-A concentrations, serum 17-OHP concentrations, serum Δ4-A in combination with 17-OHP concentrations were constructed with areas under the ROC curves (95%CI) of 0.76 (0.62, 0.90), 0.75 (0.62, 0.88), 0.69 (0.54, 0.84), P<0.05, respectively. Serum Δ4-A of 3.9 nmol/L had 0.78 of sensitivity and 0.75 of specificity in diagnosing "Poor Control". Serum 17-OHP of 7.1 µg/L has 0.67 of sensitivity and 0.71 of specificity in diagnosing "Poor Control". CONCLUSION Each of serum 17-OHP or/and Δ4-A concentration was of significance in diagnosing "Poor Control" during the glucocorticoid replacement treatment of CAH 21OHD, with the diagnostic efficacy being serum Δ4-A concentration, serum 17-OHP concentration and serum Δ4-A in combination with 17-OHP concentration in descending order. Serum Δ4-A and 17-OHP concentrations may be used as the biochemical indicators to monitor the therapy of CAH 21OHD.

Abstract
OBJECTIVES To estimate the incidence of clinically diagnosed congenital adrenal hyperplasia (CAH), clinical features and age at first presentation. To assess the potential benefit of newborn screening for CAH. DESIGN Active surveillance through the British Paediatric Surveillance Unit of all children aged under 16 years with newly diagnosed CAH, undertaken prospectively between August 2007 and August 2009. Twelve laboratories testing for CAH reported new diagnoses between August 2007 and January 2009. Reporting clinicians completed clinical questionnaires. SETTING England, Wales and Scotland. RESULTS 144 children with CAH were reported, of whom 132 (92%) had 21-hydroxylase deficiency. Thirty-six (25%) children were Asian and 62 (43%; 95% CI 35% to 51%) were boys. Incidence of new diagnoses in children ≤ 16 years was 0.60 (95% CI 0.50 to 0.71) per 100,000. Eighty-six (59%; 36 boys) children were diagnosed in the first year of life (estimated birth prevalence 5.48 (95% CI 4.42 to 6.81) per 100,000), most (77; 89%) of whom presented in the first month of life. Virilised genitalia were found in three-quarters of girls. Twenty-seven newborns first presented with salt-wasting crises, of whom 18 (67%; 16 boys) presented on or after 14 days of age. CONCLUSIONS Approximately one child in every 18 000 born in Great Britain has CAH. Similar numbers of boys and girls present clinically in the first year of life, but boys present with more severe manifestations, such as salt-wasting crises. Around 70% of newborns who first present with salt-wasting crisis would be detected earlier through newborn screening.

Abstract
Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive hereditary diseases. The impairment of cortisol synthesis leads to excessive stimulation of the adrenal glands by adrenocorticotropic hormone (ACTH), adrenal hyperplasia, and excessive androgen synthesis. The syndrome is characterised by a considerable correlation between the genotype and the phenotype with the type of CYP21A2 gene mutation affecting the severity of 21-hydroxylase deficiency. 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. Patients with CAH require constant monitoring of biochemical parameters (17a-hydroxyprogesterone and androstenedione), clinical parameters (body mass, waist circumference, blood pressure, glucose, and lipids), and bone mineral density by densitometry. The principal goal of treatment in adults with CAH is to improve quality of life, ensure that they remain fertile, reduce the manifestations of hyperandrogenisation in females, and minimise the adverse effects of glucocorticosteroid treatment. Patients with classic CAH require treatment with glucocorticosteroids and, in cases of salt wasting, also with a mineralocorticosteroid. Radical measures, such as bilateral adrenalectomy, are very rarely needed. Asymptomatic patients with non-classic CAH require monitoring: treatment is not always necessary. Medical care for patients with CAH should be provided by reference centres, as the management of such patients requires collaboration between an endocrinologist, diabetologist, gynaecologist, andrologist, urologist, and psychologist.

Abstract
OBJECTIVE To find out the frequency of nonclassical congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency among Iraqi healthy male individuals versus male patients with acne vulgaris. METHODS This case-control study and single-center examination of hormone levels in a cohort of volunteers was conducted in the Department of Dermatology, Baghdad Teaching Hospital, and in the Physiological Chemistry Department of the College of Medicine, Baghdad University, Baghdad, Iraq, from September 2007 to February 2008. RESULTS The frequency of 21-hydroxylase enzyme deficiency in healthy male subjects was 1:43 (2.3%), while in male patients with acne vulgaris, this was 6:43 (13.95%). Serum 17-hydroxyprogesterone (OHP) levels were statistically and significantly elevated in male patients with acne vulgaris compared with healthy male controls (p=0.020). The serum total cortisol level was significantly reduced in patients with acne vulgaris in comparison with that of healthy controls (p=0.022). CONCLUSION These results support the necessity of inclusion of the 21-alpha hydroxylase enzyme activity (serum 17-OHP level) screening test in acne patients.

Abstract
HYPOTHESIS Androgen excess carries varied clinical manifestations in women. Although testosterone and dehydroepiandrostendionesulfate (DHEAS) determination is considered useful in diagnostic workup, there is no laboratory definition that sufficiently describes androgen excess. DESIGN We studied 464 hirsute women with a Ferriman and Gallwey score of at least 8 between 2000 and 2005. Our examination included clinical data, total testosterone (T), sex hormone-binding globulin (SHBG), the free androgen index (FAI), and DHEAS. Additionally, androstendione, 17alpha-hydroxyprogesterone (17OHP), dehydroepiandrostendione (DHEA), and 11-deoxycortisol were determined at baseline and 60min after corticotropin challenge (250microg synacthen). RESULTS Of 464 women, 77.6% fulfilled the clinical criteria for hyperandrogenemia. Of these 360 women, 78.1% had hyperandrogenic hirsutism. Of these 281 women, 43.4% showed increased stimulation of 17OHP to 250microg of synacthen. Another 37.4% showed adrenal steroid biosynthesis defects other than 21alpha-hydroxylase deficiency, such as defective 11beta-hydroxylation or 3beta-hydroxysteroid dehydrogenase malfunction. The diagnosis of polycystic ovary syndrome was applicable to 12.4%. In addition, our results show that 72% of 281 patients with secondary hirsutism had normal T concentrations, and 55% had a normal FAI. Only 5% of hirsute patients with a normal FAI had elevated DHEAS values. However, 40% showed elevated DHEA levels, while 26% of the women with normal FAI showed androstendione values over the maximal levels in the 79 controls. CONCLUSIONS Our data suggest that in addition to testosterone and FAI, androstendione and DHEA are significantly helpful parameters in diagnosing hyperandrogenemia in hirsute women. DHEAS was not found to be helpful.

Abstract
CONTEXT In male patients with congenital adrenal hyperplasia (CAH), testicular adrenal rest tumors are frequently found that may interfere with gonadal function. OBJECTIVE Our objective was to determine steroid-producing features of testicular adrenal rest tumors. DESIGN AND SETTING The study is descriptive and took place at a university medical center. PATIENTS Eight adult CAH patients with bilateral testicular adrenal rest tumors were treated with testis-sparing surgery. INTERVENTIONS In all but one patient, spermatic veins were cannulated during surgery and blood samples collected to measure the adrenal-specific steroid 21-deoxycortisol (21DF) and 17-hydroxyprogesterone (17OHP) and androstenedione (A). The same parameters were measured in simultaneously taken peripheral blood. mRNA concentrations of adrenal-specific enzymes CYP11B1 and CYP11B2 and ACTH and angiotensin II (AII) receptors were measured in tumor tissue. MAIN OUTCOME MEASURES Adrenal-specific steroids/enzymes were assessed. RESULTS 21DF, 17OHP, and A levels were measurable in all spermatic vein samples. The ratio (mean +/- SD) between spermatic vein and simultaneously taken peripheral blood samples was 37.8 +/- 56.3 (21DF), 132.0 +/- 249 (17OHP), and 57.0 +/- 68.2 (A). CYP11B1, CYP11B2, and ACTH and AII receptor mRNAs were detected in all tumors with a strong correlation between ACTH receptor mRNA in tumors and 21DF (r = 0.85; P = 0.015), 17OHP (r = 1; P = 0.01) and A (r = 0.89; P = 0.007) concentrations in peripheral blood. CONCLUSION Testicular adrenal rest tumors produce adrenal-specific steroids and express adrenal-specific enzymes and ACTH and AII receptors, confirming the strong resemblance with adrenal tissue. Because AII receptors are present in tumor tissue, it can be hypothesized that AII may be an additional factor responsible for testicular adrenal rest tumor growth.

Abstract
OBJECTIVE To present serum androgen levels during pregnancy in a twin gestation complicated by maternal late onset 21-hydroxylase deficiency. DESIGN Case report. SETTING University teaching hospital reproductive endocrinology and infertility practice. PATIENT(S) A 27-year-old with nonclassic 21-hydroxylase deficiency and infertility, twin female fetuses, and elevated androgens. INTERVENTION(S) Steroid replacement. MAIN OUTCOME MEASURE(S) Serum T and 17-hydroxyprogesterone (17-OHP) levels. RESULT(S) Elevated androgen levels persisted throughout pregnancy in spite of aggressive steroid replacement. However, twin girls were born without any evidence of virilization. CONCLUSION(S) The changes associated with a twin gestation may result in excessive stimulation of androgens in mothers with nonclassic 21-hydroxylase deficiency. However, the increased placental aromatase provides protection.

Abstract
Autoimmune polyendocrine syndrome (APS) is the association of autoimmune endocrine diseases, with other autoimmune nonendocrine disorders. APS types 1, 2 and 4 include autoimmune adrenalitis; this suggests the presence of autoantibodies. A specific serological marker for these is the anti 21- hydroxilase autoantibody (a21-OH). APS type 2 is the association of autoimmune adrenalitis, to autoimmune thyroid disease and/or diabetes mellitus, all these are induced by autoantibodies. Alopecia, vitiligo, myasthenia and other manifestations can be minor components. We sought to establish the prevalence of seric a21-OH in patients with positive anti-microsomal fraction autoantibodies, autoimmune thyroid disease and/or non-endocrine autoimmune diseases. We also aimed to diagnose incomplete forms of APS and to follow up patients at risk of progression to complete forms of APS. A population of 72 patients and another of 60 controls with negative anti-microsomal fraction autoantibodies were studied. Elevated seric a21-OH were found in two patients. Patient A with 47 U/ml had autoimmune hypothyroidism and myasthenia; and patient B with 8.75 U/ml had autoimmune hypothyrodism and vitiligo; they both lacked adrenal insufficiency. Seric a21-OH had a prevalence of 2.8%. Regarding the adrenal component, patients A and B had an incomplete and latent APS type 2. Considering a21-OH as markers of latent endocrine autoimmune diseases and taking into account the eventual risk of developing clinical manifestations, periodic biochemical and clinical follow-ups are recommended.

Abstract
OBJECTIVE To determine the frequency of 21-hydroxylase deficiency in The Bahamas and the spectrum of this disorder METHODS Patients referred for evaluation of virilization, precocious puberty, ambiguous genitalia and salt wasting had blood taken for 17-hydroxyprogesterone (17-OH progesterone) which was measured by Enzyme-Linked Immunosorbent Assay (ELISA). RESULTS Nine patients had elevated 17-OH progesterone levels--confirming 21-hydroxylase deficiency. Range of levels was 174.9 nmol/l to 81678.7 nmol/L (normal less than 13 nmol/L). There were six females and three males and the age at diagnosis ranged from 21 days to 16 years. Five had precocious development, three had salt wasting, and there was one with virilization. One of the salt wasters had ambiguous genitalia. Incidence of 2l-hydroxylase deficiency--20/100,000; salt wasting--35/100,000; the prevalence of 21-Hydroxylase deficiency 10/100,000). CONCLUSION The frequency of 21-Hydroxylase deficiency in The Bahamas is one of the highest worldwide.

Abstract
BACKGROUND Myelolipoma is a rare benign tumor formed by mature fat tissue with strata of haematopoiesis. It is mainly asymptomatic, only large myelolipomas manifest themselves by abdominal discomfort, bleeding or by symptoms of oppressing adjacent organs. It is usually localized in the region of the adrenal gland. Myelolipomas are mostly clinically inert, only a small number of them are associated with Cushing's type of endocrine disorders, Conn's syndrome, Addison's disease, etc. PATIENT AND METHODS The authors present a rare case of a giant bilateral myelolipoma emerging out of the adrenal gland cortex in a congenital adrenal hyperplasia, with steroid 21-hydroxylase deficiency, in a woman with pronounced virilism. The principal diagnostic methods include sonography and computer tomography. The therapy available is either a surgical extirpation in the case of large or growing myelolipomas or observation in the case of small ones (< 5 cm). RESULTS The condition was resolved by bilateral adrenalectomy with extirpation of both myelolipomas and subsequent hormonal substitution treatment during which there was a gradual regression of virilising symptoms. CONCLUSIONS The coincidence of myelolipoma and congenital disorder with subsequent overproduction of the adrenocorticotropin hormone and androgens, might be explained by the incipient of myelolipoma through chronic hormonal stimulation of the adrenal gland cortex. However, the etiopathogenesis of myelolipoma is still unclear.

Abstract
BACKGROUND/AIM Nonclassical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NC-CAH) is associated with hyperandrogenemia, chronic anovulation, hirsutism, acne and adrenal hyperplasia. A few studies have shown hyperinsulinemia and insulin insensitivity in NC-CAH. Hyperinsulinemia can stimulate leptin secretion, and androgens can inhibit leptin secretion. Thus, we designed a study to investigate the insulin levels and insulin sensitivity and the effect of chronic endogenous hyperinsulinemia and androgens on leptin in patients with NC-CAH. METHODS Eighteen women with untreated NC-CAH and 26 normally cycling control women with a similar body mass index (BMI) were studied. Basal hormones, fasted and fed insulin levels, leptin and stimulated 17-hydroxyprogesterone (17-OHP) concentrations were studied. Homeostasis model assessment was used to assess insulin sensitivity. RESULTS The basal 17-OHP, the free testosterone (fT) and dehydroepiandrosterone sulfate (DHEA-S) were significantly different in the 2 groups (p < 0.05). Fasting and fed insulin levels of the NC-CAH group were higher than those of the control group (p < 0.05) and insulin sensitivity was lower in NC-CAH than in controls (p < 0.05). Insulin levels were correlated with fT and 17-OHP (p < 0.05). Serum leptin levels for NC-CAH (25.9 +/- 12.5 microg/l) did not differ from the controls (25.4 +/- 12.06 microg/l) and were positively correlated with BMI (r = 0.725) and percent body fat (r = 0.710) for both groups (both p < 0.001). Leptin levels were not correlated with estrogen or androgens, gonadotropins or insulin levels. CONCLUSION Hyperinsulinemia and insulin insensitivity associated with hyperandrogenism were detected in untreated NC-CAH patients as in previous reports, whereas serum leptin levels did not differ from those of controls.

Abstract
Salt wasting syndrome is caused by a congenital or acquired synthesis disorder or by the aldosterone function disorder. It manifests itself by ionic disorders where the sodium and chlorine level decrease with the simultaneous potassium retention. Synthesised aldosterone is in the glomerular zone of the adrenal cortex. Symptoms of dyselectrolitemia are not distinctive, they develop within a few first days of life. The suction aversion, apathy, lack of growth or progressing, body mass loss is being noticed. The most often cause of salt wasting syndrome is the congenital cortical adrenal hyperplasia (CAH) caused by 21-hydroxylase enzyme deficit. The classic form with and without salt wasting (SW), as well as non-classic form is distinguished. The therapy of SW form depends on Hydrocortisone and Cortineff administering. The other forms of salt wasting syndrome occur not so often and these are: aldosterone synthesis deficit, dehydrogenase 3beta-hydroxysteroid deficit, lipoid cortical hyperplasia, adrenal hypoplasia congenital (AHC), adrenoleukodystrophy and pseudohypoaldosteronism. The knowledge of the symptoms and causes of salt wasting syndrome allows for the proper therapeutic management and contributes to the regular psychophysical infantile development of the children.

Abstract
OBJECTIVE To assess the prevalence of autoantibodies (Abs) to tryptophan hydroxylase (TPH) and aromatic l-amino acid decarboxylase (AADC) in patients with different autoimmune diseases and to analyse their respective epitopes. DESIGN TPH and AADC Abs were measured in an immunoprecipitation assay using (35)S-labelled full-length and fragments of TPH and AADC. METHODS Patients with different autoimmune adrenal diseases (n=84), non-adrenal autoimmune diseases (n=37), idiopathic vitiligo (n=8) and 56 healthy blood donors were studied. RESULTS Fourteen of twenty-three (61%) of patients with autoimmune polyglandular syndrome (APS) type I and 1/34 (3%) of patients with isolated Addison's disease (AD) were positive for TPH Abs. None of the patients with APS type II (n=27), coeliac disease (n=10), autoimmune thyroid disease (AITD) (n=11), type 1 diabetes mellitus (DM) (n=16) or idiopathic vitiligo (n=8) was positive for TPH Abs. AADC Abs were detected in 12/23 (52%) patients with APS type I, in 1/29 (3%) patients with APS type II and 1/34 (3%) patients with isolated AD. None of the patients with coeliac disease, type 1 DM, AITD or idiopathic vitiligo was positive for AADC Abs. TPH Abs were found to interact with the C-terminal amino acids (aa) 308-423, central aa 164-205 and N-terminal aa 1-105 of the TPH molecule. AADC Ab binding epitopes were within the C-terminal aa 382-483, the central aa 243-381 and the N-terminal aa 1-167. CONCLUSIONS Our study suggests that TPH Abs and AADC Abs react with several different epitopes and that different epitopes are recognized by different sera. The prevalence of TPH Abs and AADC Abs in patients with APS type I in our study is in agreement with previous reports. TPH Abs and AADC Abs were found very rarely in patients with other forms of autoimmune adrenal disease and were not detected in patients with non-adrenal autoimmune diseases.

Abstract
We report a 6 year-old boy with the simple virilizing form of 21-hydroxylase deficiency in whom an adrenal adenoma developed following 5 years of steroid treatment. Extremely high levels of basal serum 17alpha-hydroxyprogesterone as well as an exaggerated response of 17alpha-hydroxyprogesterone to adrenocorticotropic hormone confirmed congenital adrenal hyperplasia at 7 years of age. Initially elevated serum steroid levels were restrained by high dose hydrocortisone therapy, but he chronically tended to take inadequate doses of glucocorticoid. At 12 years of age an adenoma was found in the cortex of the hyperplastic right adrenal gland. The importance of early diagnosis and compliance with medication in the simple virilizing form of 21-hydroxylase deficiency is stressed.

Abstract
Late onset congenital adrenal hyperplasia (LO CAH) can be seen in association with polycystic ovary syndrome (PCOS) or idiopathic hirsutism (IH). The study aimed to find out the prevalence of LO CAH in Central Anatolia among hirsute women. Sixty-three patients with hirsutism were evaluated to determine the frequency of LO CAH by comparing them with their age and body mass index matched 28 healthy controls. Of those 63 hirsute women, 43 were diagnosed as PCOS, and 20 were diagnosed as IH. Following basal hormonal evaluation, all subjects underwent ACTH stimulation test and ACTH stimulated 17-hydroxyprogesterone (17-OH P), 11-desoxycortisol (11-DOC), cortisol (F), and dehydroepiandrosterone sulfate (DHEA-S) levels were determined in all subjects. ACTH stimulated 17-OH P, 11-DOC, and DHEA-S levels did not differ between groups. However, stimulated F levels were found to be higher in hirsute women (p<0.001). Six out of 63 (9.52%) patients with hirsutism met the criterion for 21 hydroxylase deficiency. We found no subject presumed to have 11-beta hydroxylase deficiency, but one subject in control group (3.57%) and two patients among PCOS subjects (4.65%) had exaggerated DHEA-S response which was suggestive of mild 3-beta hydroxysteroid dehydrogenase deficiency. In conclusion, the most frequent form of LO CAH seems to be due to 21 OH deficiency among women with PCOS and IH in Central Anatolia. Mild 3-beta HSD deficiency may also be an underlying cause for hirsutism and it may be seen without any clinical presentation. Adrenal hyperactivity is likely to be the main reason of hyperandrogenemia in women with hirsutism.

Abstract
Autoimmune thyroid diseases (ATD) are often associated with Type 1 diabetes mellitus (T1DM) and Addison's disease (AD), characterizing the autoimmune polyendocrine syndrome. We evaluated the frequency of autoantibodies against glutamic acid decarboxylase isoform 65 (GAD65Ab) and 21-hydroxylase (21OHAb) in the sera of 65 [58 females (F)/7 males (M), 17-70 yr] patients with Graves' disease (GD) and 47 (45 F/2 M, 12-77 yr) with Hashimoto's thyroiditis (HT), none of whom had either diabetes or AD. The sera of 30 recently diagnosed T1DM patients (16 M/14 F, 1-39 yr) and of 97 (54 F/43 M, 7-69 yr) healthy controls were also examined. GAD65Ab were detected in the sera of 18 (60%) T1DM, 8 (12%) GD and in none of the HT patients or the controls (p = 0.03 for GD vs HT, p = 0.002 for GD vs controls, and p < 0.001 for GD vs T1DM). 21OHAb were detected in the sera of 2 (3%) GD, 1 (2%) HT and in none of the T1DM patients or the controls. GAD65Ab levels were significantly lower in GD than in T1DM patients (median: -0.06 vs 0.28, p < 0.001). Six of the 8 GD GAD65Ab-positive patients submitted to an intravenous glucose tolerance test showed no diminished first phase insulin secretion. All 21OHAb positive patients had normal basal cortisol and adrenocorticotropin (ACTH), normal cortisol response after ACTH stimulation, but high plasma renin activity. In conclusion, despite the genetic diversity of the Brazilian population, the frequency of GAD65Ab and 21OHAb in our patients is similar to that observed in other countries. GAD65Ab were more prevalent in GD than in HT patients, suggesting a difference in the immune response between these disorders. Long-term follow-up is necessary to determine the clinical relevance of these autoantibodies in the Brazilian population.

Abstract
OBJECTIVE We investigated adrenal steroidogenic function relevant to 3beta-hydroxysteroid dehydrogenase (HSD3B2) activity in vivo and HSD3B2 genotype in clinically normal family members of patients with HSD3B2 genotype-proven HSD3B2 deficiency congenital adrenal hyperplasia (CAH) to determine whether genotype-proven carriers for HSD3B2 deficiency exhibit decreased enzyme activity analogous to the mildly decreased adrenal 21-hydroxylase activity in the carriers of CYP21 gene mutation. DESIGN/PATIENTS Nineteen adult family members (ages median/range: 37/19-56 years) including 13 females and six males of six unrelated patients with HSD3B2 genotype-proven HSD3B2 deficiency were studied. MEASUREMENTS All family members had HSD3B2 DNA analysis and an ACTH stimulation test (Cortrosyn 0.25 mg IV bolus) for determination of adrenal HSD3B activity. RESULTS Ten of 13 females and five of six males were carriers of a proven or predictably deleterious mutation in one allele of the HSD3B2 gene, which was identified in the probands. ACTH-stimulated levels of 17-hydroxypregnenolone (delta5-17P), 17-hydroxyprogesterone (17-OHP), cortisol (F), dehydroepiandrosterone (DHEA) and androstenedione (delta4-A) and ratios of delta5-17P to 17-OHP, delta5-17P to F and DHEA to delta4-A, as well as increments of delta5-17P and DHEA values (ACTH-stimulated - baseline) in the genotype-proven female carriers (age, mean +/- SD: 36 +/- 6.7 years) and male carriers (age, mean +/- SD: 37 +/- 6.7 years) did not differ significantly from age-matched normal females (35 +/- 5.4 years, n = 20) and normal males (35 +/- 6 years, n = 10), respectively. There were no significant differences in any of the ACTH-stimulated hormonal levels or ratios between the female carriers with a seriously deleterious genotype (n = 5) and the female carriers with mildly deleterious genotypes (n = 5). These hormonal levels and ratios in three genotype-normal females and one genotype-normal male overlapped with those of the carriers. CONCLUSION These data suggest that normal adrenal HSD3B2 activity is maintained in the genotype-proven carriers because heterodimers of mutant and wild-type HSD3B2 enzymes may be stable and exhibit similar activity compared to homodimers of wild-type enzymes, possibly by a relatively rate-unlimited effect of haplo-wild-type enzyme activity. However, we cannot preclude entirely the possibility of a limited expression of another HSD3B activity under ACTH stimulation contributing to the normal adrenal HSD3B activity in vivo in the HSD3B2 genotype-proven heterozygotes. Which mechanism plays a role in maintaining normal enzyme activity in the heterozygotes remains to be elucidated. The hormone findings in the genotypic-proven carriers for HSD3B2 deficiency also indicate that carriers for this disorder cannot be detected by a hormone test and can only be detected by HSD3B2 genotype study.

Abstract
Increase in serum androgen levels results in suppression of serum leptin levels. In this study, the changes in serum leptin concentrations of children with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) with respect to their hyperandrogenism were investigated. Eleven children with 21-OHD and 25 healthy control children were included in the study. Before initiation of hydrocortisone, serum leptin levels in children with CAH were lower (1.7 +/- 1.3 ng/ml) than in the control group (5.3 +/- 4.01 ng/ml) (p<0.001). After three months of treatment, serum leptin levels increased to the normal range (7.1 +/- 2.9 ng/ml). Prior to and on hydrocortisone treatment in CAH, serum leptin levels were positively correlated with cortisol (r:0.78, p:0.004 and r:0.80, p:0.003) but negatively correlated with testosterone (r:-0.62, p:0.04 and r:-0.65, p:0.002). These results suggest that serum leptin measurements may be used as an additional parameter in the follow-up of children with CAH to evaluate the efficacy of hydrocortisone treatment with respect to androgenemia.

Abstract
Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency results in excessive androgen exposure in the gestational period and various degrees of masculinization of the external genitalia in female foetuses. Intrauterine gonadal steroids are not only essential for the development of the genital organs but also affect some other extragenital organ development. The second to fourth digit (2D/4D) ratio shows a sexually dimorphic pattern with longer fourth digit from second digit in men compared to women. A low 2D/4D ratio is associated with high sperm count, testosterone levels and reproductive success in men. A high 2D/4D ratio is associated with high oestrogen levels in women. Second and fourth digit ratio has also found to be correlated with sexual orientation, left hand preference autism and some adult onset diseases such as breast cancer and myocardial infarction. We found lower 2D/4D ratio in female patients with 21-hydroxylase deficiency compared to healthy girls (p=0.000) and equal 2D/4D ratio for female patients when compared to male controls. Male patients with 21-hydroxylase deficiency had significantly lower 2D/4D ratio than female and male controls in the right hand. Healthy boys had lower 2D/4D ratio than healthy girls. It is concluded that 2D/4D ratio established by intrauterine androgen levels influences the sexually dimorphic digit pattern.

Abstract
OBJECTIVE To characterize the molecular basis of the 21-hydroxylase deficiency in a group of Argentine patients presenting the classical and nonclassical forms of the disease. DESIGN To analyse the frequency of point mutations in the CYP21 gene by DNA amplification and mutation detection. PATIENTS Forty-one patients from 36 nonrelated families: 25 nonclassical (NC), 11 salt-wasting (SW) and five simple virilizing (SV). A total of 27 parents and 13 nonaffected siblings were also analysed. MEASUREMENTS Basal steroid hormones and 17-hydroxyprogesterone levels following adrenal stimulation with adrenocorticotrophic hormone were measured, together with an analysis of 10 point mutations in the CYP21 gene. RESULTS A total of 83% and 74.4% classical and nonclassical chromosomes, respectively, were characterized. The intron 2 mutation was the most prevalent among classical alleles. In addition, a high frequency for R356W was observed in both groups (13.3 and 6.9%, respectively), while V281L was the most frequent mutation among the nonclassical patients with a frequency of 39.5%. No alleles containing P30L were observed, and one de novo mutation (R356W) was found. A total of 68.3% patients were fully genotyped, and all but one showed no genotype/phenotype discrepancy. Though the cut-off value for post-ACTH 17-hydroxyprogesterone stimulation was 30.25 nmol/l (10.00 microg/l), the lowest value observed in the fully genotyped nonclassical group was 42.35 nmol/l (14.00 microg/l). CONCLUSIONS The high number of unidentified alleles in the nonclassical group suggests that less frequent mutations, or the presence of new ones, might be the cause of the disease in the Argentine population. Alternatively, the cut-off value in the ACTH-stimulated 17-hydroxyprogesterone test might overestimate the diagnosis of the nonclassical form by including some patients with heterozygous status.

Abstract
Neonatal screening for congenital hypothyroidism has been effective in early detection and treatment of the condition. The position with respect to neonatal screening for congenital adrenal hyperplasia has been debated for many years. Some countries have performed congenital adrenal hyperplasia screening for many years, others have conducted pilot studies that were then not adopted. This article endeavours to summarize the complex issues behind decisions whether to screen or not and summarizes the findings of neonatal congenital adrenal hyperplasia screening programmes.

Abstract
The effects of age on steroidogenesis in rat zona fasciculata-reticularis (ZFR) cells were studied. Young, adult, and middle-aged rats were ovariectomized (Ovx) and received replacement therapy with oil or estradiol benzoate ([EB] 25 microg/mL/kg). Rat ZFR cells were incubated with corticotropin (ACTH), prolactin (PRL), or forskolin at 37 degrees C for 1 hour. The effects of age on the activity of steroidogenic enzymes of ZFR cells were measured by the amount of intermediate steroidal products separated by thin-layer chromatography. Plasma levels were higher for PRL (54% to 254%) and corticosterone (179% to 257%) in middle-aged versus young rats. In oil-treated Ovx rats, basal and ACTH-stimulated corticosterone release by ZFR cells were also greater in middle-aged compared with young rats. Replacement with EB in Ovx rats increased the ACTH-stimulated release of corticosterone. Administration of ovine PRL in vitro resulted in a dose-dependent increase of corticosterone production. In oil-treated middle-aged rats, ovine PRL-stimulated corticosterone release was higher than in young rats. Forskolin-induced production of cyclic adenosine 3',5'-monophosphate (cAMP) was greater in middle-aged versus young rats and correlated with the increase of corticosterone production. The activity of steroidogenic enzymes in rat ZFR cells was unchanged by age. These results suggest that the age-related increase of corticosterone production in female rats is associated with the stimulatory effect of PRL on ZFR cells and is due in part to an increase of cAMP generation.

Abstract
OBJECTIVE To determine the incidence of late-onset congenital adrenal hyperplasia (LOCAH) due to 21-hydroxylase deficiency among hirsute women and to evaluate the results of the ACTH stimulation test with the clinical characteristics. STUDY DESIGN Prospective, controlled study. One hundred women with hirsutism and 14 normally cycling women without hirsutism were included in this study at the Division of Reproductive Endocrinology, Department of Obstetrics and Gynecology, Cerrahpasa School of Medicine, Istanbul University. After basal serum progesterone (P) and 17 hydroxyprogesterone (17OHP) levels were determined, an ACTH stimulation test was performed on cycle day 3-5. The same parameters were checked 30 minutes later. We estimated the 21 hydroxylase activity by calculating the change in 17OHP (17OHP 30-0) and the summed rate of the change in P and 17OHP ([P30-0] + [17OHP30-01/30 minutes). The 95th percentile for these estimates in normal women were calculated, and values above three times the 95th percentile were considered to distinguish women with LOCAH due to 21-hydroxylase deficiency. RESULTS The 95th percentile for 17OHP 30-0 and (P30-0) + (17OHP30-0)/30 minutes in normal women was 1.6 and 8.9 ng/dL/min, respectively. Regarding 17OHP 30-0 values, three women with hirsutism had levels above three times the 95th percentile of these estimates, and 28 women had estimates of more than the 95th percentile but less than threefold. Seventeen of 28 women had oligomenorrhea, and all had severe hirsutism. The women with severe hirsutism and oligomenorrhea had significantly higher ACTH-stimulated serum 17OHP levels and values for 17OHP 30-0 and (P30-0 + (17OHP30-0)/30 min) than did normally cycling women. CONCLUSION The incidence of LOCAH due to 21-hydroxylase deficiency and mild 21-hydroxylase deficiency is 3% and 28%, respectively, in women with hirsutism. Clinical characteristics are not helpful in determining 21-hydroxylase deficiency. However, the incidence of 21-hydroxylase deficiency is more common among women with severe hirsutism and oligomenorrhea. The change in serum 17OHP 30-0 seems to be greater than the summed rate of change in serum 17OHP and P in the detection of 21-hydroxylase enzyme deficiency.

Abstract
Approximately 70-80% of cases of primary adrenal insufficiency are classified as idiopathic. An effective protocol for the etiological diagnosis of primary adrenal insufficiency is needed to ensure correct patient management. With the aim of developing an algorithm for the etiological diagnosis of primary adrenal insufficiency, we studied 56 Italian patients with nonsurgical primary adrenal insufficiency and 24 French patients with X-linked adrenoleukodystrophy (ALD) for serum levels of adrenal cortex, steroid-21-hydroxylase (21OHAb), islet cell (ICA), glutamate decarboxylase (GAD65Ab), IA2/ICA512 (ICA512Ab), thyroid peroxidase (TPOAb) autoantibodies, and plasmatic concentrations of very long chain fatty acids (VLCFA). High levels of 21OH and adrenal cortex antibodies were found in 35/42 (83%) and 17/42 (40%) Italian patients with idiopathic adrenal insufficiency, respectively. Levels of adrenal autoantibodies correlated inversely with disease duration (P < 0.0001). Elevated VLCFA were found in 4/42 (10%) idiopathic patients. A total of 34/35 (97%) idiopathic patients with a disease duration of less than 20 yr was positive for either 21OHSAb or elevated levels of VLCFA. None of 14 patients with posttuberculosis adrenal insufficiency had elevated levels of either adrenal antibodies or VLCFA. ICA, GAD65Ab, ICA512Ab, and TPOAb were found in 6/56 (11%), 8/56 (14%), 4/56 (7%), and 23/56 (41%) patients, respectively. None of 24 French ALD patients with adrenal insufficiency was positive for organ-specific autoantibodies. The measuring of 21OH antibodies and plasma VLCFA levels enabled a correct diagnosis of autoimmune (89%) and ALD (8%) in 97% of patients with idiopathic primary adrenal insufficiency of less than 20 yr of duration. The results of our study have important therapeutic and prognostic implications.

Abstract
Blood samples for plasma steroid hormone determinations and molecular genotype analysis of the 21-hydroxylase gene (CYP21) were obtained from 15 infants identified through a voluntary newborn screening program. Mutations were identified on both CYP21 alleles in 12 (80%) of 15 infants; all had confirmatory plasma 17-hydroxyprogesterone concentrations > 3500 ng/dl. No patient was found to carry mutations associated with late-onset 21-hydroxylase deficiency. Newborn screening hastened diagnosis in eight infants.

Abstract
One of the major complications of glucocorticoid treatment is bone loss. 21-Hydroxylase deficiency is the most frequent inborn error of steroidogenesis, leading to congenital adrenal hyperplasia (CAH): synthesis of cortisol is impaired and replacement therapy is therefore mandatory. We studied the bone mineral density in a group of patients with congenital adrenal hyperplasia (CAH) on long-term glucocorticoid replacement therapy. We selected 30 Caucasian patients with CAH due to 21-hydroxylase deficiency (mean +/- SD age = 17.45 +/- 2.49 years). 22 patients had the classical CAH form and the remaining 8 had the nonclassical (late-onset) form. The mean duration of therapy was 15.20 +/- 4.04 years. Bone mineral density (BMD) was evaluated with a dual-energy X-ray absorptiometer. BMD was also measured in 73 healthy white volunteers of comparable age (17.35 +/- 2.99 years). BMD values of the spine (sBMD), total body (TBBMD), legs, and arms of CAH patients, adjusted for confounding variables (age, gender, body mass index), did not differ from those of control subjects (p = 0.86; p = 0.17; p = 0.06 and p = 0.26, respectively). sBMD and TBBMD values did not show relationships with the duration of treatment and the dose of corticosteroids. Patients with the classical form of CAH had bone density values comparable with those of patients with the nonclassical form (sBMD: p = 0.33; TBBMD: p = 0.97). Our data show that, despite long-term treatment with glucocorticoids, CAH patients have bone density values comparable with controls.

Abstract
During pregnancy, C21 steroids such as progesterone (P4), and cortisol (F), have been reported to be closely involved in uterine contraction. To clarify the association between changes in steroid hormones and the onset of delivery, we measured the concentrations of six C21 steroids in maternal blood by high performance liquid chromatography. Changes in each steroid hormone were evaluated by analysis of variance during pregnancy. Pregnenolone, a source of C21 steroids, gradually increased during pregnancy. P4 and 17P4, its metabolite, reached a peak 3 weeks before delivery and noticeably decreased thereafter. Accompanying a decrease in P4 and 17P4, 20P4 and F, its metabolite, were noticeably increased. The association among these steroid hormones was also evaluated. The correlation between P4 and F was reversed after 3 weeks before delivery. These results suggest that steroid hormones in the maternal blood begin to change dynamically about 3 weeks before delivery. In particular, a decrease in P4 and an increase in F seem to be closely related to the onset of delivery.

Abstract
OBJECTIVE Recent studies have indicated that the syndrome of congenital adrenal hyperplasia due to 21-hydroxylase deficiency is closely associated with the development of benign adrenocortical tumours. Tumour formation is thought to be a consequence of ACTH hypersecretion which results from the lack of glucocorticoid synthesis. The aim of this study was to evaluate 21-hydroxylase activity in patients with an incidentally discovered adrenal mass ('incidentaloma') without a history of congenital adrenal hyperplasia. DESIGN A prospective study of 52 patients admitted to a single hospital. PATIENTS Fifty-two consecutive subjects (mean age 56.0 years, range 24-81 years) with an incidentally discovered adrenal tumour were studied. MEASUREMENTS The 21-hydroxylase reserve was assessed by intravenous bolus administration of 1-24 ACTH (tetracosactrin) with measurement of basal and stimulated serum 17 alpha-hydroxyprogesterone (17-OHP) concentrations. Impaired 21-hydroxylase activity was defined as an exaggerated 17-OHP response, with a 17-OHP increment exceeding 7.9 nmol/l. Basal and stimulated cortisol concentrations, and basal ACTH were also measured. RESULTS Baseline levels of 17-OHP were normal in 44 and elevated in 8 subjects. In 37 patients (71.2%), the 17-OHP increment following ACTH administration exceeded 7.9 nmol/l, demonstrating mildly decreased 21-hydroxylase activity. In these subjects, the peak serum 17-OHP correlated with the tumour diameter. In the patients with apparently normal 21-hydroxylase activity, no significant correlation was found between 17-OHP concentrations and tumour size. All patients had a stimulated serum cortisol above 550 nmol/l reflecting intact adrenal glucocorticoid reserve. There were no other differences between the group with exaggerated and the group with normal 17-OHP increment. The tumours were removed from two women with augmented 17-OHP responses and this was followed by normalization of 17-OHP dynamics. CONCLUSIONS Biochemical evidence for partial 21-hydroxylase defiency is a common finding in patients with an adrenal incidentaloma, even in the absence of a congenital adrenal hyperplasia history. Exaggerated 17-OHP increment is not accompanied by decreased adrenal glucocorticoid reserve. Normalization of the 17-OHP response after surgical treatment suggests that the phenomenon results from reduced 21-hydroxylase activity in the tumour, which retains ACTH responsiveness.

Abstract
There is little information about the plasma concentrations of 3 beta-hydroxy-delta 5-steroids (delta 5-steroids) in untreated patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency. To further study the delta 5 pathway, we measured plasma levels of delta 5- and delta 4-steroids in 21 adult patients with different degrees of 21-hydroxylase deficiency (11 salt-wasters, 5 simple virilizers, and 5 patients with the nonclassical form of the disease). In all patients, investigations were performed after withdrawal of steroid treatment for at least 10 days. In addition, catheterization of gonadal and adrenal veins was performed in two salt-wasting male patients displaying bilateral testicular tumors to study adrenal secretion of delta 5- and delta 4-steroids. In one of them, surgical resection of the intratesticular adrenal rests gave the opportunity to measure 3 beta-hydroxysteroid dehydrogenase (3 beta HSD) activity. In all untreated patients, an increase in plasma delta 4-steroids was observed. In contrast, although plasma levels of dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) were not significantly modified in simple virilizers, a paradoxical decrease in all delta 5-steroids was observed in salt-wasters. Catheterization of the adrenal veins confirmed the decrease in delta 5-steroids, particularly DHEA and DHEAS. The androstenedione/DHEA ratio was increased in all patients proportionally to the severity of the disease, suggesting an increase in adrenal 3 beta HSD. In vitro analysis of 3 beta HSD activity showed a 4-fold increase in intratesticular adrenal tissue compared to that in normal adrenals. A positive correlation between the androstenedione/DHEA ratio and plasma ACTH levels was observed, suggesting a long term stimulatory effect of ACTH on 3 beta HSD. Angiotensin-II could have an additive effect on ACTH-induced 3 beta HSD activity.

Abstract
21-Hydroxylase-deficient late-onset adrenal hyperplasia (LOAH) appears to affect 1-6% of hyperandrogenic women. Screening and diagnostic criteria for LOAH have not been well established, as these patients are clinically indistinguishable from other hyperandrogenic women. The following prospective study was undertaken to 1) determine the predictive value of screening hyperandrogenic women for LOAH with a morning follicular phase basal 17-hydroxyprogesterone (17-HP) level and 2) compare the various in vivo estimates of 21-hydroxylase activity after adrenal stimulation for the diagnosis of LOAH. Twenty-one euandrogenic control women (physically normal, without hirsutism, with regular menses, and a negative family history) were studied. The clinical population consisted of 164 consecutive unselected patients seen at the Division of Reproductive Endocrinology and Infertility of Johns Hopkins University School of Medicine between 1983 and 1987 demonstrating hirsutism and/or hyperandrogenic oligomenorrhea. Controls and patients underwent acute adrenal stimulation with 1 mg ACTH-(1-24), administered in the morning to fasting patients in the follicular phase of their menstrual cycle. Blood was sampled before and 30 min after ACTH-(1-24) administration. Steroid RIA determinations were performed for 17-HP, progesterone, testosterone, dehydroepiandrosterone sulfate, androstenedione, FSH, LH, and PRL. Three estimates of 21-hydroxylase activity were studied: the 17-HP level 30 min post-ACTH (17-HP30), the change in 17-HP (delta 17-HP0-30) and the summed rate of change in 17-HP and progesterone ([delta 17-HP0-30) + delta P0-30]/30 min). The upper 95th percentiles for these estimates of 21-hydroxylase activity in control women were 9.6 nmol/L (316 ng/dL), 8.8 nmol/L (292 ng/dL), and 0.39 nmol/L.min (13 ng/dL.min), respectively. Thirteen of 164 (7.9%) hyperandrogenic women had at least 1 abnormal 21-hydroxylase measurement. Four of these women (2.4%) had 17-HP measurements 3- to 20-fold above the upper normal 95th percentile (17-HP30 greater than 36.3 nmol/L or 1200 ng/dL) and were considered as suffering from LOAH. In our population the 3 measures of 21-hydroxylase studied clearly differentiated the LOAH women from all others, although a single 17-HP level 30 min post-ACTH was the simplest and most cost effective. Nine other hyperandrogenic women (5.5%) had at least 1 abnormal 21-hydroxylase measurement less than 3-fold the upper normal 95th percentile value and were designated as having mild 21-hydroxylase deficiency.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
We describe 5 adult women with severe hirsutism due to late onset 21-hydroxylase deficiency. Diagnosis was performed on the finding of high serum 17-hydroxyprogesterone (17OHP) levels with a marked hyperresponse to an ACTH test. The endocrine study showed in most patients a gonadotropin behavior similar to that observed in classical polycystic ovary (PCO) syndrome. Prolactin levels were slightly increased in basal conditions and presented an exaggerated response to TRH stimulation.
