Primary aldosteronism is most often caused by aldosterone-producing adenoma (APA) and bi-lateral adrenal hyperplasia. Most APAs are caused by somatic mutations of various ion channels and pumps, the most common being the inward-rectifying potassium channel KCNJ5. Germ line mutations of KCNJ5 cause familial hyperaldosteronism type 3 (FH3), which is associated with severe hyperaldosteronism and hypertension. We present an unusual case of FH3 in a young woman, first diagnosed with primary aldosteronism at the age of 6 years, with bilateral adrenal hyperplasia, who underwent unilateral adrenalectomy (left adrenal) to alleviate hyperaldosteronism. However, her hyperaldosteronism persisted. At the age of 26 years, tomography of the remaining adrenal revealed two different adrenal tumors, one of which grew substantially in 4 months; therefore, the adrenal gland was removed. A comprehensive histological, immunohistochemical, and molecular evaluation of various sections of the adrenal gland and in situ visualization of aldosterone, using matrix-assisted laser desorption/ionization imaging mass spectrometry, was performed. Aldosterone synthase (CYP11B2) immunoreactivity was observed in the tumors and adrenal gland. The larger tumor also harbored a somatic β-catenin activating mutation. Aldosterone visualized in situ was only found in the subcapsular regions of the adrenal and not in the tumors. Collectively, this case of FH3 presented unusual tumor development and histological/molecular findings. 相似文献

A 14.5-year-old male dog was presented with stranguria and hematuria of 1-month duration. Hematology and blood chemistry revealed a neutrophilia, mild azotemia and a mild decrease in the packed cell volume. Urinalysis showed high specific gravity (> 1.040 g/mL), hematuria, proteinuria and mild bilirubinuria. On physical examination, a firm oval mass located caudal to the distended urinary bladder, was palpated. Differential diagnoses included prostatitis, prostatic neoplasm, prostatic hyperplasia, and abscess. The enlarged prostate was suspected to be the cause of hematuria, and a total prostatectomy was performed. Histologically, the prostate was affected by a prostatitis with cystic papillary hyperplasia of the epithelium. The dog's condition continued to deteriorate, and death occurred 1 week later. Necropsy showed a tumor mass, approximately 5 x 4 x 3 cm in size, between the abdominal aorta and the left kidney, where the adrenal glands were embedded. Lesions were found in the kidneys, adrenal gland, lungs, heart, liver, intestine, and serosa of viscera, while the spleen was spared. This hemangiosarcoma most likely arose from the renal arteries, resulting in diffuse lesions in the kidneys thought to be the cause of hematuria. 相似文献

The adrenal gland is an essential stress-responsive organ that is part of both the hypothalamic-pituitary-adrenal axis and the sympatho-adrenomedullary system. Chronic stress exposure commonly increases adrenal weight, but it is not known to what extent this growth is due to cellular hyperplasia or hypertrophy and whether it is subregion specific. Moreover, it is not clear whether increased production of adrenal glucocorticoid after chronic stress is due to increased sensitivity to adrenocorticotropic hormone (ACTH) vs. increased maximal output. The present studies use a 14-day chronic variable stress (CVS) paradigm in adult male rats to assess the effects of chronic stress on adrenal growth and corticosterone steroidogenesis. Exogenous ACTH administration (0-895 ng/100 g body wt) to dexamethasone-blocked rats demonstrated that CVS increased maximal plasma and adrenal corticosterone responses to ACTH without affecting sensitivity. This enhanced function was associated with increased adrenal weight, DNA and RNA content, and RNA/DNA ratio after CVS, suggesting that both cellular hyperplasia and hypertrophy occurred. Unbiased stereological counting of cells labeled for Ki67 (cell division marker) or 4,6-diamidino-2-phenylindole (nuclear marker), combined with zone specific markers, showed that CVS induced hyperplasia in the outer zona fasciculata, hypertrophy in the inner zona fasciculata and medulla, and reduced cell size in the zona glomerulosa. Collectively, these results demonstrate that increased adrenal weight after CVS is due to hyperplasia and hypertrophy that occur in specific adrenal subregions and is associated with increased maximal corticosterone responses to ACTH. These chronic stress-induced changes in adrenal growth and function may have implications for patients with stress-related disorders. 相似文献

Compensatory adrenal growth after unilateral adrenalectomy (ULA) leads to adrenocortical hyperplasia. Because zonal growth contributions are not clear, we characterized the phenotype of cortical cells that proliferate using immunofluorescence histochemistry and zone-specific cell counting. Rats underwent ULA, sham adrenalectomy (sham), or no surgery and were killed at 2 or 5 days. Adrenals were weighed and sections immunostained for Ki67 (proliferation), cytochrome P-450 aldosterone synthase (P450aldo, glomerulosa), and cytochrome P-450 11beta-hydroxylase (P45011beta, fasciculata). Unbiased stereology was used to count proliferating glomerulosa and fasciculata cells. Adrenal weight increased after ULA compared with sham and no surgery at both time points, and there was no difference between sham and no surgery. However, either ULA or sham increased Ki67-positive cells in the outer fasciculata at both time points compared with no surgery. Outer fasciculata-restricted proliferation is thus associated with adrenal weight gain in ULA but not sham. Experiment repetition using proliferating cell nuclear antigen and bromodeoxyuridine showed similar results. After ULA, adrenal DNA, RNA, and protein increased at both time points, whereas after sham, only adrenal DNA increased at 2 days. Compensatory growth thus results from hyperplasia and hypertrophy, whereas sham induces only a transient adrenal hyperplasia. Dexamethasone pretreatment prevented the increase in adrenal weight after ULA and blocked Ki67 labeling in the outer fasciculata but not zona glomerulosa in all groups. These results clearly show that the outer fasciculata is the primary adrenal zone responsible for compensatory growth, responding to steroid-suppressible stress signals that alone are ineffective in increasing adrenal mass. 相似文献

Increased amounts of circulating mineralocorticoid receptor binding substances presumed to be natural antagonists were previously demonstrated in congenital adrenal hyperplasia. In this study the feasibility of using urinary extracts for the identification of such binding substances was investigated. Urinary extracts from patients with the 21-hydroxylase defect did contain greater than normal amounts of mineralocorticoid receptor binding material. When subjected to chromatographic separation using a radioreceptor assay to follow the course of fractionation, a major aldosterone binding competitor was identified. On the basis of its chromatographic mobility in comparison with the labeled steroid, radioimmunoassay, ultraviolet absorption and radio-receptor assay of the native and acetylated derivative, the component was identified as 11-deoxycorticosterone and its structure confirmed by mass spectrometry. Although the major mineralocorticoid receptor binding component proved not to be an antagonist but an agonist, the results are in keeping with other evidence for overproduction of 11-deoxycorticosterone in the simple virilizing form of the disorder. Our finding did not disprove the existence of a circulating mineralocorticoid antagonist in congenital adrenal hyperplasia, but demonstrate that the major receptor binding substance in urinary extracts in that disorder is the mineralocorticoid agonist, 11-deoxycorticosterone. 相似文献

OBJECTIVE: A patient is reported with hypertension due to combined medullary adrenal hyperplasia and myelolipoma. METHODS: A 52-year-old woman with long-standing hypertension was evaluated for an incidentally discovered large tumor of the left adrenal. Left adrenalectomy was performed for a presumptive clinical diagnosis of pheochromocytoma. RESULTS: Histopathologic examination revealed a mixed tumor consisting of a large myelolipoma with infiltrating foci of adrenal medulla. CONCLUSIONS: A patient is described with hypertension, myelolipoma and adrenal medullary hyperplasia; following adrenalectomy, however, blood pressure and biochemical abnormalities normalized. 相似文献

A comparative study of adrenal morphology between normal fetuses and those with anencephaly or congenital adrenal hyperplasia (CAH) was performed in order to examine the hypothesis that fetal adrenal mass and structure are adrenocorticotrophin (ACTH)-dependent throughout gestation. Combined adrenal weight in 102 normal fetuses was used to establish a reference range for the gestational ages of 15-27 weeks. During this period, mean adrenal weight showed a 6-fold linear increase. In 38 anencephalic fetuses of similar gestation age, adrenal weight was below the normal range and did not show a rise. Three fetuses with CAH (18, 22 and 30 weeks gestation) had adrenal weights considerably above the normal range. Adrenal cortical thickness was significantly increased in CAH fetuses, largely as a consequence of cell hypertrophy, whereas decreased cortical thickness in the anencephalic group represented cellular hypoplasia. Conspicuous secretory granules in the cytoplasm was the electron-micrographic feature of the adrenal gland in the 22-week fetus with CAH. These observations are consistent with close dependency of fetal adrenal growth and development upon fetal pituitary function from an early age, mediated primarily through ACTH. 相似文献

The renin-angiotensin system was studied in eight patients with Cushing's syndrome (four with adrenal adenoma and four with adrenal hyperplasia) and in five normal controls. Basal plasma renin activity (PRA) and aldosterone concentration (PAC) were similar in supine position among Cushing's syndrome due to adrenal adenoma (PRA; 1.0 +/- 0.3 ng/ml/h, PAC; 7.4 +/- 1.0 ng/dl, mean +/- SE), those due to adrenal hyperplasia (1.0 +/- 0.2, 6.9 +/- 0.8) and the controls (0.8 +/- 0.1, 6.4 +/- 0.4). The PRA after furosemide (1 mg/kg i.v.) and 120 min. upright posture stimulation was similar among Cushing's syndrome due to adrenal adenoma (2.2 +/- 0.7 ng/ml/h), those due to adrenal hyperplasia (2.6 +/- 1.7) and the controls (2.5 +/- 1.2). However, the PAC response after the stimulation in Cushing's syndrome due to adrenal hyperplasia (7.1 +/- 1.2 ng/dl) was significantly lower than that in the controls (17.5 +/- 2.1) (p less than 0.01), although there was no significant difference between the PAC response in Cushing's syndrome due to adrenal adenoma (12.6 +/- 1.0) and the controls. These results indicate that PAC response to furosemide and upright pasture stimulation might be suppressed in Cushing's syndrome due to adrenal hyperplasia. 相似文献

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. 相似文献

ObjectiveTo study the effect of adding metformin to standard steroid replacement therapy in a patient with classic salt-losing congenital adrenal hyperplasia due to 21- hydroxylase deficiency with suboptimal biochemical and clinical control.MethodsWe present the clinical and laboratory findings before and after the addition of metformin to the therapeutic regimen of the study patient.ResultsA 17-year-old girl had been diagnosed as a neonate with classic salt-losing congenital adrenal hyperplasia caused by 21-hydroxylase deficiency (CYP21A2 deficiency). She was treated with hydrocortisone, 20 mg in the morning and 10 mg at bedtime, and fludrocortisone, 50 mcg daily. While on steroid replacement, she maintained normal serum electrolytes, glucose, blood pressure, and external genitalia, but she continued to express clinical features of obesity, hirsutism, amenorrhea, and acanthosis nigricans. Elevated laboratory measurements included the following: fasting 17-hydroxyprogesterone, 3410 ng/dL; total testosterone, 326 ng/dL; and androstenedione, 390 ng/dL. She was initiated on metformin, 500 mg twice daily after meals. After 3 months, the patient lost 2 kg, amenorrhea resolved, 17-hydroxyprogesterone decreased to 1539 ng/dL, total testosterone decreased to 163 ng/dL, and androstenedione levels remained unchanged.ConclusionsMetformin, an agent known to reduce insulin resistance, further suppressed the 17-hydroxyprogesterone concentration in a patient with classic congenital adrenal hyperplasia on steroid replacement therapy. Metformin may improve clinical and biochemical outcomes in classic congenital adrenal hyperplasia without the risk of iatrogenic Cushing syndrome. (Endocr Pract. 2008;14:889-891) 相似文献

Objective: Females with the severe classic forms of congenital adrenal hyperplasia reportedly have a higher frequency of atypical gender identity, nonheterosexual sexual relationships, and cross-gender role behavior. Comparable data and quality-of-life measures among those with the milder, more prevalent form, nonclassic congenital adrenal hyperplasia, are scarce. We aimed to assess health-related quality of life, gender identity, role, and sexual orientation in women with nonclassic congenital adrenal hyperplasia via a prospective, questionnaire-based, case-control study.Methods: Thirty-eight women with nonclassic congenital adrenal hyperplasia (median age 34 years; range, 18 to 44 years) and 62 age-matched female controls were recruited. Outcome measures included the Multi-Gender Identity, Sexuality, and World Health Organization (WHO) quality-of-life questionnaires.Results: Sociodemographic parameters (marital status, number of children, and educational level) were similar for both groups, as were most measures of the Multi-Gender Identity, Sexuality, and WHO quality-of-life questionnaires. However, “sometimes-feeling-as-a-man and sometimes-feeling-as-a-woman” were more frequently reported in the study group compared to the controls (7/38 [18.4%] vs. 3/62 [4.8%], respectively; P = .02). Furthermore, more nonclassic congenital adrenal hyperplasia women reported first falling in love with a woman (4/37 [10.8%] vs. 0/58 [0%]; P = .02).Conclusion: Our findings suggest possible subtle differences in gender identity and sexual orientation between adult nonclassic congenital adrenal hyperplasia females and controls. Quality of life was not impaired in individuals within the study group. The impact of exposure to mildly elevated androgen levels during childhood and adolescence on the female brain warrants more in-depth assessment in further studies.Abbreviations: CAH = congenital adrenal hyperplasia; Multi-GIQ = Multi-Gender Identity Questionnaire; NCCAH = nonclassic congenital adrenal hyperplasia; QoL = quality of life 相似文献

A 67-year-old man affected by prostate cancer was incidentally found to have a nodular enlargement of the left adrenal gland without apparent changes in hormonal status. The adrenal mass was found to be scintigraphically active, the radiolabelled compound being concentrated in its context with a consensual suppression of the contralateral uptake. The patient underwent a resection of the adrenal tumor. Histologically and biochemically, the adrenal mass was found to be a non-functioning adenoma. The radioisotopic uptake along with the non-hormonal activity prompted us to call this tumor "Pre-Cushing's syndrome" of the adrenal cortex. 相似文献

5β-Pregnane-3α, 17α, 20α, 21-tetrol (l) and 5β-pregnane-3α, 17α 20β, 21-tetrol (II) have been isolated and identified from the urine of a girl with congenital adrenal hyperplasia. The total 5β-pregnane-3α, 17α, 20(α+β),21-tetrol consisted of 60% of I and 40% of II. The final identity of the compounds was established by gas chromatography — mass spectrometry. The mass spectra of the two trimethylsilyl isomers were closely related to each other in contrast to the spectra of five other pairs of C21-C-20(α and β)-hydroxy steroid-trimethylsilyl-ethers. The mass spectra of free I and II also exhibited many common features, but were less similar to each other than their trimethylsilyl derivatives. 相似文献

Context
The deficiency of steroid 11β-hydroxylase is caused by mutations in the CYP11B1 gene and is the second major form of congenital adrenal hyperplasia associated with hypertension.Objective
The objective of this study was to screen the CYP11B1 gene for mutations in one Vietnamese male suffering from congenital adrenal hyperplasia.Patient
The patient (46,XY) had congenital adrenal hyperplasia. The clinical manifestations presented precocious puberty, hyper-pigmentation and high blood pressure at 4 years.Results
The patient was a homozygous carrier of a novel mutation located in exon 7 containing a premature stop codon instead of tyrosine at 395 (p.Y395X).Conclusion
We have identified a novel mutant of the CYP11B1 gene in one Vietnamese family associated with phenotypes of congenital adrenal hyperplasia. The mutant gene p.Y395X produces a truncated form of the polypeptide and abolishes the enzyme activities, leading to a severe phenotype of congenital adrenal hyperplasia. 相似文献15.

Objective:In contrast to the high incidence of testicular adrenal rest tumors in adult male patients with congenital adrenal hyperplasia (CAH), ovarian adrenal rest tumors (OARTs) in female CAH patients are rare. In this case report, we describe a case of bilateral OART in a female patient with CAH due to 21-hydroxylase deficiency.Methods:We present a detailed case report with the clinical, imaging, and laboratory findings of the patient. The pertinent literature is also reviewed.Results:A 17-year-old patient was known to have CAH due to 21-hydroxylase deficiency. Since the second month of her gestational age, her mother was treated with cortisone-replacement therapy. The patient was treated with hydrocortisone and fludrocortisone since the neonatal period. Her pertinent history included a bilateral adrenalectomy at the age of 13 years in 2006, and for 3 years she led a normal puberty life with no complaint with hormonal replacement therapy. Nevertheless, in 2009, she developed a virilizing syndrome. Subsequently, she underwent surgery in December 2009 for right adnexectomy. However, the regression of the masculinizing mass was not complete and worsened several months after the surgery. A new pelvic magnetic resonance image showed the activation of a contralateral ovarian mass, necessitating a left adnexectomy in August 2010.Conclusion:This case demonstrates some interesting features of OART that pose challenges to its management. If an OART is detected early enough and glucocorticoid therapy is received, it is possible that the OART will decrease in size following suppression of adrenocorticotropic hormone levels.

Objective: Nonclassic congenital adrenal hyperplasia (NCCAH) is a late-onset milder form of congenital adrenal hyperplasia that differs dramatically from the classic form. Health-related quality of life (HRQOL) in pediatric patients with the sole diagnosis of NCCAH has not been determined; therefore, in this study, we aimed to determine whether HRQOL is compromised in comparison to the general population.Methods: Single-center, cross-sectional, case-control study. Twenty-three hydrocortisone-treated children and adolescents (7 males) diagnosed with NCCAH by cosyntropin stimulation test and CYP21A2 gene mutation analysis were recruited to this study; 6 healthy siblings were also recruited. HRQOL was assessed by the child and parent-proxy PedsQL Inventory and compared between NCCAH subjects and healthy siblings. HRQOL scores of NCCAH subjects were compared with known standards from the U.S. and Israeli general healthy populations. Anthropometric measurements of children and parents were performed and compared between NCCAH subjects and healthy siblings. Pearson correlation coefficients were calculated.Results: HRQOL scores of the participants and parents did not differ between NCCAH subjects and healthy siblings. The HRQOL emotional domain scores of the NCCAH patients and parent were significantly lower than the healthy U.S. pediatric population (P = .046) but not different from established standards of the healthy Israeli population (P = .583). Anthropometric measurements were within the normal range and did not differ between NCCAH subjects and their siblings. Total, school functioning, and psychosocial HRQOL domain scores were positively correlated with body mass index–standard deviation score in NCCAH subjects.Conclusion: HRQOL was not adversely affected by NCCAH among adequately treated children and adolescents.Abbreviations: BMI = body mass index; CAH = congenital adrenal hyperplasia; HRQOL = health-related quality of life; NCCAH = nonclassic congenital adrenal hyperplasia; PedsQL = Pediatric Quality of Life Inventory; SDS = standard deviation score 相似文献

Cushing's syndrome due to unilateral adrenal nodular hyperplasia with incomplete inhibition of the contralateral gland 总被引:1,自引:0,他引:1
A 57-year-old woman was demonstrated to be affected by adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome. Computed-axial tomography of the abdomen demonstrated an expansion of the left adrenal. In apparent contrast with these findings, adrenal scintigraphy demonstrated radiocholesterol uptake also by the right gland. At surgery, the left adrenal was found to be hard and enlarged and was excised, while the right gland was found of normal appearance and left in place. Histologic examination of the excised gland demonstrated nodular hyperplasia. Early after surgery, plasma cortisol returned to normal values with a normal circadian rhythm and complete inhibition by low dose dexamethasone; the response of plasma cortisol to ACTH was normal. The patient represents a rare case of unilateral adrenal nodular hyperplasia. Radiocholesterol uptake by the contralateral gland and early recovery from adrenal atrophy after surgery are exceptional findings and suggest incomplete inhibition of endogenous ACTH. 相似文献

ObjectiveTo report a rare case of multiple unilateral adrenal adenomas in which immunohistochemistry results confirmed primary hyperaldosteronism in each of 3 adenomas.MethodsWe present the clinical, laboratory, radiographic, and pathologic findings of a case of multiple unilateral adrenal adenomas.ResultsAlthough multiple nodules in both adrenal glands are fairly common in patients with bilateral hyperplasia, multiple unilateral nodules are extremely rare. A 45-year-old woman with a long-standing history of severe hypertension was found to have biochemical parameters consistent with primary hyperaldosteronism, multiple unilateral adrenal adenomas, and immunohistochemical test results confirming primary hyperaldosteronism arising from each of 3 adrenal nodules (measuring 2.2 × 2.2 cm, 1.7 × 0.7 cm, and 0.5 × 0.5 cm).ConclusionThis case illustrates the rare presentation of primary hyperaldosteronism as multiple unilateral adrenal adenomas in which immunohistochemistry results can confirm the suspected preoperative diagnosis as suggested by biochemical and radiographic evidence.

ObjectiveTo report a case of congenital adrenal hyperplasia due to CYP17 deficiency caused by a novel CYP17A1 mutation.MethodsWe describe the clinical, biochemical, genetic, and radiologic findings of a sporadic case of congenital adrenal hyperplasia due to CYP17 deficiency in a young patient.ResultsAn 18-year-old woman presented with hypogonadism and progressive muscle weakness and had not yet undergone thelarche, adrenarche, and menarche. Blood pressure was 155/90 mm Hg, she had no axillary or pubic hair, breasts were Tanner stage 1, and female genitalia were Tanner stage 1. Further laboratory studies showed hypokalemia with metabolic alkalosis, hypergonadotropic hypogonadism, a 46,XY karyotype, a low 17-hydroxyprogesterone level, and a high deoxycorticosterone level. Sequencing of the CYP17A1 gene demonstrated homozygous transversion of cytosine to adenine (TCAàTAA) in exon 5, which causes a premature stop codon at position 288 (Ser288X). Imaging studies showed large adrenal glands, cystic picture in the inguinal canal (suggestive of intra-abdominal testes), and absent Müllerian structures. Exploratory laparotomy was performed to remove the remaining gonads, and the final histologic examination showed atrophic testes.ConclusionsCongenital adrenal hyperplasia due to CYP17 deficiency should be suspected in patients with hypertension, hypokalemic alkalosis, and hypogonadism. In such cases, it is mandatory to assess the karyotype and perform hormonal and molecular genetic studies. (Endocr Pract. 2011;17:99-103) 相似文献

ObjectiveTo review the association between congenital adrenal hyperplasia (CAH) and adrenal myelolipomas and report a case of bilateral, giant adrenal myelolipomas in a patient with untreated CAH due to 21-hydroxylase deficiency.MethodsWe describe the patient’s clinical presentation, imaging findings, and laboratory test results and review the relevant English-language literature concerning patients with both CAH and myelolipomas.ResultsA 45-year-old man with untreated CAH due to 21-hydroxylase deficiency presented with increasing abdominal girth and abdominal pain. Computed tomography of the abdomen demonstrated very low-density adrenal masses (22 × 11 cm on the left side and 6 × 5.5-cm on the right side) consistent with adrenal myelolipomas. The left adrenal myelolipoma was resected (24.4 × 19.0 × 9.5 cm; 2557 g). The mass was composed of mature adipose tissue with areas of hematopoietic cells of myeloid, erythroid, and megakaryocytic cell lines. Islands of adrenal cortical cells were scattered between the adipose and hematopoietic tissue. Including the present case, we identified 31 patients with both CAH and myelolipomas who have been described in the English-language literature. The details of these cases were reviewed.ConclusionsPersons with CAH may be at increased risk of developing adrenal myelolipomas, particularly if their CAH is poorly controlled. How and whether chronic exposure of the adrenal glands to high corticotropin levels increases the risk of developing myelolipomas remains a matter of speculation. (Endocr Pract. 2011;17:441-447) 相似文献
