Symptom complex due to ACTH production by non-pituitary neoplasms.
Syndromes resulting from inappropriate production of HORMONES or hormone-like materials by NEOPLASMS in non-endocrine tissues or not by the usual ENDOCRINE GLANDS. Such hormone outputs are called ectopic hormone (HORMONES, ECTOPIC) secretion.
A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.
Tumors or cancer of the BRONCHI.
An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
A usually small, slow-growing neoplasm composed of islands of rounded, oxyphilic, or spindle-shaped cells of medium size, with moderately small vesicular nuclei, and covered by intact mucosa with a yellow cut surface. The tumor can occur anywhere in the gastrointestinal tract (and in the lungs and other sites); approximately 90% arise in the appendix. It is now established that these tumors are of neuroendocrine origin and derive from a primitive stem cell. (From Stedman, 25th ed & Holland et al., Cancer Medicine, 3d ed, p1182)
A characteristic symptom complex.
A malignant olfactory neuroblastoma arising from the olfactory epithelium of the superior nasal cavity and cribriform plate. It is uncommon (3% of nasal tumors) and rarely is associated with the production of excess hormones (e.g., SIADH, Cushing Syndrome). It has a high propensity for multiple local recurrences and bony metastases. (From Holland et al., Cancer Medicine, 3rd ed, p1245; J Laryngol Otol 1998 Jul;112(7):628-33)
A disease of the PITUITARY GLAND characterized by the excess amount of ADRENOCORTICOTROPIC HORMONE secreted. This leads to hypersecretion of cortisol (HYDROCORTISONE) by the ADRENAL GLANDS resulting in CUSHING SYNDROME.
Hormones released from neoplasms or from other cells that are not the usual sources of hormones.
An inhibitor of the enzyme STEROID 11-BETA-MONOOXYGENASE. It is used as a test of the feedback hypothalamic-pituitary mechanism in the diagnosis of CUSHING SYNDROME.
A 30-kDa protein synthesized primarily in the ANTERIOR PITUITARY GLAND and the HYPOTHALAMUS. It is also found in the skin and other peripheral tissues. Depending on species and tissues, POMC is cleaved by PROHORMONE CONVERTASES yielding various active peptides including ACTH; BETA-LIPOTROPIN; ENDORPHINS; MELANOCYTE-STIMULATING HORMONES; and others (GAMMA-LPH; CORTICOTROPIN-LIKE INTERMEDIATE LOBE PEPTIDE; N-terminal peptide of POMC or NPP).
Tumors or cancer of the THYMUS GLAND.
The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.
Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
A peptide of about 41 amino acids that stimulates the release of ADRENOCORTICOTROPIC HORMONE. CRH is synthesized by neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, CRH stimulates the release of ACTH from the PITUITARY GLAND. CRH can also be synthesized in other tissues, such as PLACENTA; ADRENAL MEDULLA; and TESTIS.
A chromosome disorder associated either with an extra chromosome 21 or an effective trisomy for chromosome 21. Clinical manifestations include hypotonia, short stature, brachycephaly, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, Simian crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE. (Menkes, Textbook of Child Neurology, 5th ed, p213)
A cluster of metabolic risk factors for CARDIOVASCULAR DISEASES and TYPE 2 DIABETES MELLITUS. The major components of metabolic syndrome X include excess ABDOMINAL FAT; atherogenic DYSLIPIDEMIA; HYPERTENSION; HYPERGLYCEMIA; INSULIN RESISTANCE; a proinflammatory state; and a prothrombotic (THROMBOSIS) state. (from AHA/NHLBI/ADA Conference Proceedings, Circulation 2004; 109:551-556)
Systems designed to provide information primarily concerned with the administrative functions associated with the provision and utilization of services; also includes program planning, etc.
A pituitary adenoma which secretes ADRENOCORTICOTROPIN, leading to CUSHING DISEASE.
A group of hydroxycorticosteroids bearing a hydroxy group at the 17-position. Urinary excretion of these compounds is used as an index of adrenal function. They are used systemically in the free alcohol form, but with esterification of the hydroxy groups, topical effectiveness is increased.
Excess production of ADRENAL CORTEX HORMONES such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE. Hyperadrenal syndromes include CUSHING SYNDROME; HYPERALDOSTERONISM; and VIRILISM.
Tumors or cancers of the ADRENAL CORTEX.

Severe muscle weakness due to hypokalemia as a manifestation of small-cell carcinoma. (1/112)

We describe the case of a 56-year-old man with severe muscle weakness due to heavy hypokalemia (serum potassium 1.44 mmol/l) associated with inappropriate kaliuria and alkalemia. Subsequent investigation revealed the presence of ectopic ACTH hypersecretion due to a small-cell lung carcinoma. A significant clinical/laboratory improvement was achieved following chemotherapy-induced regression of the primary tumor. The profound hypokalemia was probably the result of cortisol hypersecretion, which in concert with the ACTH-induced decreased 11beta-hydroxysteroid dehydrogenase activity can exhibit an increased mineralocorticoid activity. In addition, other ACTH-dependent mineralocorticoids may play a contributory role in the development of severe hypokalemia.  (+info)

Carcinoid-associated ectopic ACTH syndrome with variable response to octreotide. (2/112)

The case is presented of a 31-year-old woman who developed florid clinical and biochemical Cushing's syndrome due to metastatic hepatic carcinoid tumour from a probable pancreatic primary. Hypercortisolaemia was controlled with metyrapone and ketoconazole, but high doses of octreotide failed to affect plasma cortisol and urinary 5-hydroxyindole acetic acid (5HIAA) levels, or prevent rapid tumour growth. Hepatic polystyrene embolisation failed, and she was treated by liver transplantation with initial excellent results, and normalisation of cortisol and 5HIAA levels. Ten months later, however, she relapsed with bony and pelvic tumour recurrence, and high and symptomatic levels of cortisol and 5HIAA. At this time, octreotide in similar doses to those used previously appeared to normalise her biochemically, although she died soon after. This variable responsiveness to octreotide could be related to somatostatin receptor changes, or cyclical tumour secretion patterns.  (+info)

Marked increase in plasma ACTH with tumor reduction after chemotherapy in ectopic ACTH syndrome. (3/112)

We report on a case of rapid and marked hormone release as a result of rapid tumor reduction due to chemotherapy in a 36-year-old woman with ectopic ACTH syndrome due to small cell lung cancer. Treatment of the cancer with cisplatin and etoposide resulted in an 80% reduction in tumor size on computed tomographic scan within two weeks. Concurrently, plasma ACTH exhibited an unexpected and astonishing increase from 373 pg/ml before treatment to more than 1200 pg/ml. There were no biochemical characteristics observed in tumor lysis syndrome of solid tumors such as azotemia, increased LDH and hyperkalemia. The present case indicates that anticancer chemotherapy instituted in patients with ectopic ACTH syndrome could result in an acute increase of plasma ACTH and exacerbation of hypercortisolism, similar to tumor lysis syndrome, which is a potentially fatal complication following anti-cancer chemotherapy.  (+info)

Is whole-lung CT scanning still necessary in all cases of ACTH-dependent Cushing's syndrome in the era of petrosal sinus sampling? (4/112)

We reviewed 31 patients in whom both bilateral inferior petrosal sinus sampling without CRH stimulation, and a CT scan of the lungs were done. Twenty-five had normal lung CT scans, of whom 23 had a higher inferior petrosal sinus: peripheral ACTH ratio > or = 1.5. After careful follow-up, none was subsequently shown to have ectopic ACTH syndrome. Six had abnormal lung CT scans, of whom two had ratios > or = 1.5. In these two patients, other investigations suggested pituitary disease, and pituitary surgery led to apparent cure. Of the remaining four patients, who had ratios < 1.5, two had incidental lung findings, and pituitary abnormalities were demonstrated at pituitary surgery. The third underwent bilateral adrenalectomy, and no evidence of ectopic ACTH syndrome has emerged as yet after 4 years follow-up. The fourth had a small-cell carcinoma of the lung, confirmed histologically. Our series suggests that whole-lung CT scanning is only necessary in cases of ACTH-dependent Cushing's syndrome where bilateral inferior petrosal sinus sampling has not demonstrated a significant increase in petrosal sinus ACTH levels as compared with the peripheral level. Thus, in our experience the test is now only necessary in those patients (approximately 25%) where the ratio is < or = 1.5.  (+info)

Thymic hyperplasia as a source of ectopic ACTH production. (5/112)

A 26 year-old man with suspected Cushing's disease underwent transsphenoidal exploration of the pituitary without any evidence of microadenoma or hyperplasia. Progressive hypercortisolism necessitated bilateral adrenalectomy. Postoperatively, skin pigmentation gradually developed with a marked elevation of plasma ACTH levels, and CT scanning uncovered a thymic mass. Following removal of the thymic mass, skin pigmentation disappeared and plasma ACTH levels fell to normal. The excised mass was found to be a benign thymic hyperplasia without epithelial or carcinoid tumor cells. However, gel chromatography showed that the thymic tissue extract contained high ACTH content comparable to that of ectopic ACTH-producing tumors with a major component corresponding to ACTH(1-39). Northern blot analysis and in situ hybridization revealed the expression of proopiomelanocortin transcripts in lymphocytes of thymic hyperplasia. This report suggests that lymphocytes in thymic hyperplasia are the most likely site of deregulated ACTH expression causing ectopic ACTH syndrome.  (+info)

Clinical implications of glucocorticoid metabolism by 11beta-hydroxysteroid dehydrogenases in target tissues. (6/112)

11beta-Hydroxysteroid dehydrogenases (11beta-HSD) are microsomal enzymes that catalyze the conversion of active glucocorticoids (GC) to their inactive 11-dehydro products and vice versa. Two isoenzymes of 11beta-HSD have been characterized and cloned in human tissues. The tissue-specific metabolism of GC by these enzymes is important for mineralocorticoid (MC) and GC receptor occupancy and seems to play a crucial role in the pathogenesis of diseases such as apparent MC excess syndrome, and may play roles in hypertension, obesity and impaired hepatic glucose homeostasis. This article reviews the literature and examines the role and importance of 11beta-HSD in humans.  (+info)

A new generation IRMA for ACTH with improved specificity: validation in various physiological and pathological conditions. (7/112)

OBJECTIVE: Measurement of plasma ACTH is a key step for the exploration of hypothalamic-pituitary-adrenal disorders. To further improve ACTH recognition a new generation of ACTH IRMA was developed using antibodies directed towards succinylated ACTH (sACTH IRMA). DESIGN: The usefulness of this assay was compared with that of another commercially available ACTH IRMA assay using intact ACTH (ELSA-ACTH) in various pathophysiological situations: patients with low ACTH plasma levels, high ACTH plasma levels with normal or tumoural pituitaries, or ectopic ACTH syndrome, and pregnant women with high proopiomelanocortin (POMC) plasma levels. METHODS: All plasma samples were assayed simultaneously with the two different IRMAs. Comparisons were assessed by plotting the results along the theoretical line of identical values, and by the graphical method of Bland and Altman. RESULTS: In the ELSA-ACTH IRMA, CLIP (or ACTH18-39) showed true cross-reactivity, and alpha-melanocyte-stimulating hormone and purified POMC both interfered and induced falsely lower ACTH results; in the sACTH IRMA no peptide showed any cross-reactivity, and only extremely high values of CLIP (50 000 pg/ml) interfered and induced falsely lower ACTH results. In ACTH hypersecretory syndromes, of tumoural (Cushing's disease, ectopic ACTH secretion) or non-tumoural (Addison's disease, congenital adrenal hyperplasia) origins a good agreement between the two assays was observed except for very high ACTH plasma values (above 1000 pg/ml) and in some tumours where the sACTH IRMA yielded lower results; in some cases, the presence of circulating CLIP, demonstrated by HPLC studies, may contribute to this discrepancy. It is also likely that the calibration of the ELSA-ACTH kit itself generates higher ACTH values. In normal pregnant women both IRMAs gave highly correlated values, yet lower results were obtained with the sACTH IRMA. CONCLUSION: These data show that the sACTH IRMA has improved qualities of specificity and usefulness for rapid assessment of ACTH plasma levels.  (+info)

Ectopic adrenocorticotropin syndrome exhibiting paradoxical adrenocorticotropin responsiveness to gonadotropin-releasing hormone. (8/112)

In a 37-year-old man who had Cushing's syndrome, investigations, including overnight dexamethasone suppression test, corticotropin-releasing hormone (CRH) test, pituitary MRI and inferior petrosal sinus sampling suggested the presence of ectopic adrenocorticotropin (ACTH) production. Interestingly, gonadotropin-releasing hormone (GnRH) increased plasma ACTH from 73 pg/ml to 708 pg/ml at 15 min. Furthermore, desmopressin also increased plasma ACTH whereas CRH and thyrotropin-releasing hormone (TRH) had no effect. Such paradoxical responses of plasma ACTH were observed repeatedly. A thoracic CT scan revealed a right anterior mediastinal mass, which was surgically resected. Histological and immunohistochemical examination confirmed that the tumor was an ACTH-producing carcinoid. ACTH and cortisol decreased immediately following surgery. Neither desmopressin nor GnRH administration resulted in elevation of plasma ACTH while ACTH-responsiveness to dexamethasone and CRH was restored. To our knowledge, this is the first report documenting GnRH responsiveness in ectopic ACTH syndrome.  (+info)

Ectopic secretion of ACTH is an infrequent cause of Cushings syndrome. We report a case of ectopic ACTH syndrome caused by a nasal paraganglioma, a 68-year-old female with clinical features of Cushings syndrome, serious hypokalaemia and a right paranasal sinus lesion. Cranial magnetic resonance image showed a 46-mm mass on the right paranasal sinuses. Endocrinological investigation confirmed the diagnosis of ectopic ACTH production. Resection of the tumour normalised ACTH and cortisol secretion. The tumour was found to be a paraganglioma through microscopic analysis. On follow-up 3 months later, the patient showed nearly complete clinical recovery. Ectopic ACTH syndrome due to nasal paraganglioma is extremely uncommon, as only two other cases have been discussed in the literature. ...

Secretion of ectopic adrenocorticotropic hormone (ACTH) with consequently Cushings syndrome is a rare paraneoplastic phenomenon. It has been described in a variety of malignancies, like bronchial carcinoids, small-cell lung carcinoma, thymoma, pancreatic carcinoma and other. In many cases of suspected ectopic ACTH secretion, it is difficult to histologically or cytochemically confirm the diagnosis. We present a 63-year-old woman with a recurrent poorly differentiated squamous cell lung carcinoma with clinical and biochemical features consistent with ectopic Cushings syndrome. Immunocytochemical staining confirmed the secretion of ACTH by tumour cells. (c) 2005 Elsevier Ireland Ltd. All rights reserved. ...
Results: Patients (n=124) with Cushings disease had younger age (40.4±11.6 vs. 53.4±16.1 years), longer disease courses (24.0 vs. 3.0 months) and greater diastolic blood pressure (95±14 vs. 87±11 mmHg) than those (n=17) with ectopic adrenocorticotropic hormone (ACTH) syndrome (P,0.05). Compared with ACTH independent syndrome (n=85), ACTH dependent syndrome (n=141) had significantly (P,0.05) lower potassium (3.30±0.68 vs 3.58±0.62mmol/L) and chloride (101.8±5.2 vs. 104.3±4.2 mmol/L) but significantly (P,0.05) greater pH value, bicarbonate radicals, base excess, and CO2CP/K ratio (9.3±4.6 vs 7.5±2.4).

Cushings Disease: This syndrome is caused by tumors on the ACTH secreting cells of the pituitary gland. patients with this problem develop fat deposits in strange places , spontaneous scarring of the skin along the belly that looks striated, pimples in adult, high blood pressure and elevated body temperature. These tumors are usually so small that the surgeon might have a difficult time finding the little bad pearl in the gland during surgery. This is the one time when small can be bad, especially if the surgeon is unable to locate and remove the tumor! ACTH secreting tumors, although small and troublesome, are readily cured by surgery alone Pituitary adenomas have been known to make levels of ACTH rise and fall, Thus making cortisol do the same.Id would be asking for another MRI of the Pituitary gland.

The protein encoded by this gene acts as receptor for arginine vasopressin. This receptor belongs to the subfamily of G-protein coupled receptors which includes AVPR1A, V2R and OXT receptors. Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system. The receptor is primarily located in the anterior pituitary, where it stimulates ACTH release. It is expressed at high levels in ACTH-secreting pituitary adenomas as well as in bronchial carcinoids responsible for the ectopic ACTH syndrome. A spliced antisense transcript of this gene has been reported but its function is not known. [provided by RefSeq, Jul 2008 ...
Cushing Syndrome is an endocrine disorder causing an over production of the hormone cortisol. Cortisol is produced in the adrenal gland as a response to the production of ACTH in the pituitary gland.. Between 10% and 20% of patients with hypercortisolism (Cushing Syndrome) have ectopic production of the hormone ACTH. Meaning, the hormone is not being released from the normal site, the pituitary gland. In many cases the ectopic ACTH is being produced by a tumor of the lung, thymus, or pancreas. However, in approximately 50% of these patients the source of the ACTH cannot be found even with the use of extensive imaging studies such as CT scans, MRIs, and nuclear scans (111-indium pentetreotide). The ability of these tests to locate the source of the hormone production is dependent on the changes of anatomy and / or the dose and adequate uptake of the radioactive agent. The inability to detect the source of ectopic ACTH production often results in unnecessary pituitary surgery or ...

What Is Cushings? Cushings syndrome, also known as hypercortisolism or hyperadrenocorticism, is an endocrine disorder caused by prolonged exposure of the bodys tissues to high levels of the hormone cortisol (in the blood) from a variety of causes, including primary pituitary adenoma (known as Cushings disease), primary adrenal hyperplasia or neoplasia, ectopic ACTH production (e.g., from a small cell lung cancer), and iatrogenic (steroid use). It is relatively rare and most commonly affects adults aged 20 to 50. An estimated 10 to 15 of every million people are affected each year. Cushings was discovered by American physician, surgeon and endocrinologist Harvey Cushing (1869-1939) and reported by him in 1932. Normally, cortisol is released from the adrenal glands in response to ACTH being released from the pituitary gland. Both Cushings syndrome and Cushings disease are characterized by elevated levels of cortisol in the blood, but the cause of elevated cortisol differs between the two. ...

Bilateral inferior petrosal sinus (IPS) sampling after ovine corticotropin-releasing hormone (oCRH) stimulation is an established technique for the differentiation of pituitary from nonpituitary sources of adrenocorticotropic hormone (ACTH) production. The purpose of this study was to review our experience to determine the sensitivity and specificity of bilateral IPS sampling. METHODS: Between January 1990 and February 1997, 92 patients underwent 94 IPS sampling procedures. Indications for these patients with Cushings syndrome included no discrete lesion on MR images or CT scans, a discrete lesion ...
Pancreatic neuroendocrine tumors (pNETs) causing ectopic adrenal corticotropic hormone (ACTH) syndrome (EAS) are rare and aggressive with little known information. We aimed to elucidate the clinical features and molecular mechanisms of pNETs with EAS by methylation analysis. Seven patients with ectopic ACTH-secreting pNETs who were diagnosed at Shanghai Clinical Endocrine and Metabolic Diseases Center and Pancreatic Disease Center in Ruijin Hospital between 2001 and 2019 were enrolled. Twenty patients with ectopic ACTH-secreting thymic neuroendocrine tumors (TNETs) and 7 with nonfunctional pNETs (nf-pNETs) were also enrolled as controls. We collected clinical data and measured POMC promoter CpG methylation. All 7 patients had elevated ACTH and urinary free cortisol (UFC) levels with positive ACTH staining in the pancreas and were diagnosed with ectopic ACTH-secreting pNET. Of the 7 patients, 6 underwent surgery and 1 underwent transarterial embolization (TAE). Two patients were free of disease ...
Bronchial carcinoid tumors are very rare pulmonary neoplasms. They usually present with pulmonary symptoms or paraneoplastic syndromes. Typical (well-differentiated) tumors are usually indolent with survival exceeding 90% after resection. Atypical carcinoids have a worse prognosis. They are much more likely to recur locally or to have distant metastases. This case report describes a patient who presented with abdominal pain and hepatic lesions who was subsequently diagnosed to have bronchial carcinoid.

en] Cushings syndrome (CS) is characterized by pathologically elevated free glucocorticoid levels. Endogenous hypercortisolism is usually due to ACTH-secreting pituitary corticotropic adenomas and less often due to ectopic ACTH-secreting neuroendocrine neoplasms or ACTH-independent adrenal cortisol hypersecretion. CS is a serious chronic disease leading to a several-fold increase in cardiovascular morbidity and mortality. Multiple genetic alterations have been described in the setting of sporadic corticotropinoma formation. Changes in the expression profiles have been demonstrated in growth factors and their receptors, cell-cycle regulators and in various genes related to hormonal gene transcription, synthesis and secretion. Sporadic adrenal adenomas and carcinomas may demonstrate dysfunction in genes such as TP53 among others. Cushings disease can be an inherited condition also. Multiple endocrine neoplasia type 1 (MEN1) and familial isolated pituitary adenomas (FIPA) together account for 5% ...

Diabetes mellitus (DM) is a common comorbidity of Cushings syndrome (CS) and plays an important role in morbidity and death of patients with uncontrolled hypercortisolism. Some authors define DM in CS as a specific type of diabetes secondary to endocrinopathy, although others judge it as a classical form of type 2 DM. Glucocorticoid (GC) excess causes pancreatic beta cell dysfunction and insulin resistance, which correlates with hypercortisolism level. If Cushings disease (CD) remission implicates on DM resolution remains unclear. ...

Synevo. Hormonul adrenocorticotrop (corticotropina sau corticostimulina) este constituit dintr-un lant polipeptidic format din 39 aminoacizi. Sinteza de ACTH are loc in celulele bazofile adenohipofizare dintr-un precursor denumit proopiomelanocortin1;5.. ACTH controleaza dezvoltarea si secretia hormonala a corticosuprarenalei. Prin stimularea zonei fasciculate a corticosuprarenalelor activeaza sinteza si secretia de glucocorticoizi (cortizol si corticosteron). Efectele stimulatoare ale ACTH asupra secretiei corticosuprarenalei sunt mediate de AMP ciclic1.. Proprietatile secundare ale ACTH se datoreaza efectelor metabolice ale hormonilor glucocorticoizi, activand metabolismele glucidic, protidic si lipidic1.. Reglarea secretiei de ACTH se realizeaza pe cale neuroumorala cu participarea indirecta a hipotalamusului. Principalul factor umoral de reglare il constituie concentratia sanguina a hormonilor glucocorticoizi, indeosebi a cortizolului. Sub influenta acestora, secretia de ACTH scade, ...
