Radioimmunoassay for 11-deoxycortisol using iodine-labeled tracer. (1/89)

A simple and sensitive radioimmunoassay for 11-deoxycortisol was developed. The antiserum produced in rabbits by immunizing with a complex of 11-deoxycortisol-3-oxime and bovine serum albumin (BSA) has little cross-reactivity with other endogenous steroids. The immunoassay procedure requires only one-step ethanol denaturation of binding proteins in plasma and extraction by an organic solvent can be omitted. Furthermore, use of 125I-labeled tracer significantly simplify the counting procedure. The method is sensitive enough to detect 1 microng/100 ml of 11-deoxycortisol. Plasma 11-deoxycortisol levels measured by this method after the administration of a single dose of metyrapone ranged from 5.0 to 19.2 microng/100 ml, whereas they were 0 to 4.0 microng/100 ml in hypopituitary patients. It is concluded that this simple method is useful for the routine assay of plasma 11-deoxycortisol as a parameter of the metyrapone tests.  (+info)

A case of renin-producing adrenocortical cancer. (2/89)

Here we report a case of a renin-producing adrenocortical carcinoma. A 57-year-old woman was referred to our hospital complaining of thirst and generalized muscle weakness. She was diagnosed as being hypertensive and diabetic with associated hypokalemia and she had a hard elastic mass with a diameter of 10 cm on the left side of her neck. An abdominal computed tomography scan revealed a suprarenal mass on the left side (8.5 x 8 x 6.5 cm). Endocrinological examination demonstrated a marked elevation in the patient's serum glucocorticoid and sex steroid hormones as well as plasma renin activity. Histological examination of a sample taken from the neck mass revealed a metastasis from an adrenal carcinoma, which was stained positively with antibodies against cytochrome P450 and renin, establishing the diagnosis of a renin-producing adrenocortical carcinoma. Trilostane was effective in reducing serum cortisol levels, but mitotane was ineffective.  (+info)

Nonchromatographic radioimmunoassay of plasma 11-deoxycortisol, for use in the metyrapone test, with polyethylene glycol as the precipant. (3/89)

We have developed a simple, reliable radioimmunoassay for plasma 11-deoxycortisol. The method does not require chromatography but instead makes use of a simple extraction procedure which, in combination with the antibody characteristics, is highly specific for the metyrapone test. Polyethylene glycol was used to separate free and antibody-bound steroid. The smallest amount measurable is 15 pg (2.0 mug/liter of plasma). The method is shown to be precise and accurate. Intraassay precision of the method for two plasma pools was 26.7 plus or minus 2.5 mug/liter (CV equals 9.4%) and 61.2 plus or minus 3.7 mug/liter (CV equals 6.0%). The respective inter-assay precision was 27.0 plus or minus 1.7 mug/liter (CV equals 6.3%) and 59.9 plus or minus 2.3 mug/liter (CV equals 3.8%). The validity of the assay was further verified by evaluating the plasma 11-deoxycortisol response to metyrapone administration. The relative simplicity of the method and the commercial availability of all reagents, including antisera, makes this radioimmunoassay procedure practical for use in clinical laboratories.  (+info)

The biochemical study of intermaxillary fixation (IMF) stress in oral surgery inpatients. (4/89)

Although intermaxillary fixation (IMF) is performed to treat the patients with maxillary fracture, this procedure is very stressful to the patients. IMF has been reported to increase noradrenaline (NA) release in the brain and elevate plasma corticosterone contents in the rat. These changes were significantly attenuated by diazepam, an anxiolytic of the benzodiazepine family. These results suggest that IMF could greatly affect the pituitary-adrenal system as a stress. In the present study, in order to examine the influence of IMF on the human body function, we measured levels of 17-hydrocorticosteroids (17-OHCS) and 17-ketosteroid (17-KS), which are metabolites of the adreno-cortical hormone cortisol, in the urine of inpatients undergoing IMF. The subjects were requested to fill out a questionnaire on irritableness caused by IMF. In these patients, urinary 17-OHCS levels were significantly increased after IMF and well correlated to the results of the questionnaire. The finding suggested that urinary 17-OHCS levels reflect stress related to IMF, and that such stress mainly causes an irritated feeling. Natural killer cell activity (NK activity), which is considered to be related to stress, was measured in these patients. The relationship between 17-OHCS levels and NK activity was examined in reference to the results of the questionnaire. Questionnaire showed that most patients noted insomnia and an irritated feeling during IMF. To examine the influence of anxiolytic agents on stress related to IMF, an anxiolytic agent, ethyl loflazepate, was administered during IMF, and urinary 17-OHCS levels were measured. There was no correlation between 17-OHCS levels and NK activity in the patients. Furthermore, no correlation was observed between visual analogue scale (VSA) and NK activity. Increases in 17-OHCS levels in the group treated with ethyl loflazepate, an anxiolytic of the benzodiazepine family, were significantly lower than in the untreated group. This suggests that ethyl loflazepate reduced stress responses to IMF. It has been reported that NK activity is reduced inpatients with depression or chronic fatigue syndrome. However, NK activity may not be affected by mechanical stress such as IMF. The finding that an anxiolytic agent, ethyl loflazepate, inhibited stress responses to IMF further suggests that anxiolytic drugs are very useful for treatment of irritated feeling of the patients undergoing IMF.  (+info)

Involvement of the cholinergic pathway in the pathogenesis of pituitary Cushing's syndrome. (5/89)

Transsphenoidal adenomectomy is currently the first choice for treatment of patients with pituitary ACTH-dependent Cushing's syndrome. However, pharmacotherapy is prescribed for some patients, e.g., unsuccessful surgery. We treated a woman in whom pituitary Cushing's syndrome was improved while she was on antimuscarinic cholinergic agents, atropine sulphate and pirenzepine hydrochloride. The diminished effect of anticholinergics on ACTH and cortisol was incidentally identified in an inferior petrosal sinus sampling procedure. A single intramuscular injection of atropine significantly decreased both ACTH (43.9 pg/ml to less than 12.0; normal, 12.0-40.0 pg/ml) and cortisol (29.9 microg/dl to 13.6; normal, 7.6-23.6 microg/dl). An M1-muscarinic receptor specific antagonist, pirenzepine hydrochloride, also had a diminishing effect on these hormones and this inhibiting effect was partially blocked by the simultaneous administration of an anticholinesterase agent, pyridostigmine bromide. Chronic oral ingestion of these agents led to improvement in clinical symptoms, and urinary 17-hydroxycorticosteroid and 17-ketosteroid levels were at normal to upper-normal levels. This is the first documentation of involvement of the cholinergic system in the pathogenesis of pituitary Cushing's syndrome.  (+info)

Parallel radioimmunoassay for plasma cortisol and 11-deoxycortisol. (6/89)

We describe a direct, rapid, and specific procedure for the parallel radioimmunoassay for cortisol and 11-deoxycortisol in plasma. The plasma sample is used directly, after heat inactivation of the natural cortisol-binding protein. The radioimmunoassay utilizes antibodies generated in rabbits by steroids congugated at their 3-oxo position to thyroglobulin. Ammonium sulfate is used to separate bound and free steroids. Our cortisol antibody and an 11-deoxycortisol antibody obtained elsewhere cross reacted negligibly with each other or with other steroids that might be present in plasma. Radioimmunoassays were therefore developed for both steroids in only 1.25 mul of plasma. The intra- and inter-assay coefficients of variation for both steroids were less than 10%, with a sensitivyt of 4 mug/liter. Steroid values obtained by a competitive protein binding method were consistently higher than those of the present method, suggesting that the former is measuring total corticosteroids. This simple approach requires only 4 h for the specific measurement of both cortisol and 11-deoxycortisol in 20 samples of plasma.  (+info)

A natural history of adrenocorticotropin-independent bilateral adrenal macronodular hyperplasia (AIMAH) from preclinical to clinically overt Cushing's syndrome. (7/89)

A 49-year-old man was referred to our hospital for the treatment of gallstones in 1993. Bilateral adrenal nodular masses were detected incidentally by abdominal computed tomography. He had no clinical signs of Cushing's syndrome such as central obesity, striae of skin and diabetes mellitus. We performed cholecystectomy and partial adrenalectomy of right adrenal gland as a biopsy, and diagnosed him as preclinical Cushing's syndrome due to adrenocorticotropin-independent bilateral adrenal macronodular hyperplasia (AIMAH) based on endocrinological and histological examinations. We followed him up for 7 years. During the observation period, the sizes of both adrenal glands increased gradually, and finally serum cortisol level increased beyond normal range, and he showed a Cushingoid appearance such as moon face and central obesity. His skin became atrophic and very fragile, and the bone mineral density of his lumbar spine was extremely low. Serum cortisol level was elevated, and plasma ACTH level was always suppressed. Urinary excretion of 17-hydroxycorticosteroid and free cortisol were increased. Diurnal rhythm of cortisol and ACTH was completely lost and high dose (8 mg/day) dexamethasone did not suppress urinary 17-hydroxycorticosteroid excretion. He became clinically overt Cushing's syndrome. We recommended total adrenalectomy, but he refused it. It is important to know the natural history of preclinical Cushing's syndrome due to AIMAH when choosing an adequate treatment.  (+info)

Enzyme induction by enflurane in man. (8/89)

Concentrations of 6-beta-hydroxycortisol (6-OHF), a polar metabolite of cortisol formed in the endoplasmic reticulum (microsomes) of the liver, and 17-hydroxycorticosteroids (17-OHCS) were measured in the urines of six healthy adult male volunteers exposed to a mean of 9.6 MAC-hours of enflurane anesthesia as an index of possible enzyme induction. The ratio of 6-OHF to 17-OHCS in 24-hour urine specimens collected five days before anesthesia was compared with the ratio of these metabolites in 24-hour urine specimens collected 16 to 18 hours after anesthesia. The ratio of 6-OHF to 17-OHCS increased markedly in five and decreased slightly in one volunteer following anesthesia. The results indicate that enflurane may cause induction of hepatic microsomal enzymes.  (+info)

Effect of altered acid-base balance, induced by the intravenous infusion of either hydrochloric acid or sodium bicarbonate, on adrenocortical function in anesthetized dogs was studied. The secretory activity of the adrenal cortex was determined by measuring 17-hydroxycorticosteroids in adrenal venous blood. Adrenocortical stimulation occurred in dogs with a profound decrease in arterial ph and bicarbonate concentration in the presence of a normal arterial CO2 tension (acid infusions) and in dogs with increased arterial CO2 tension and bicarbonate concentration in the presence of a normal arterial ph (bicarbonate infusions). It is concluded that concomitant alterations in both arterial ph and CO2 tension are not required to initiate an adrenocortical response, and it is suggested that a suitable change in either of these factors may act as a pituitary-adrenocortical stimulus.. ...

E. coli Source ß-Glucuronidases ß-Glucuronidase is a ~290 kDa tetrameric protein with an isoelectric point of 4.8.1 Unlike the enzyme preparations from mollusks that naturally contain ß-glucuronidase and sulfatase activities in almost equal amounts, the preparation of ß-glucuronidase from E. coli is essentially free of sulfatase activity. The enzyme from E. coli has a high rate of hydrolytic activity and it retains this activity during hydrolysis better than similar enzymes that are more sensitive to changes in the concentration of ß-glucuronide conjugates. The enzyme preparation from E. coli has been shown to be useful for determining the presence of androsterone, 17-hydroxycorticosteroids, and estriol in urine.2 The E. coli enzyme has also been shown to be more active against estrogen conjugates than other sources of the enzyme.3 Optimal pH: 6-7 References1.

The metyrapone test has been improved by specific measurement of plasma 11-deoxycortisol. This simplified method measures 11-deoxycortisol and cortisol in a sample of 0.1 ml of plasma after a standard dose of metyrapone. In normal patients, after metyrapone ingestion, plasma 11-deoxycortisol rises from a base line of 0.8 ± 0.8 µg/100 ml to 16.8 ± 4.4 µg/100 ml, and plasma cortisol falls from 13.5 ± 5.1 µg/100 ml to 3.3 ± 2.8 µg/100 ml. After metyrapone 11-deoxycortisol is reduced only in adrenocorticotrophin (ACTH) deficiency. Patients with hypopituitarism or chronic corticoid therapy and 9 of 12 acromegalics had subnormal levels. Patients with the empty sella syndrome or trophic hormone deficiency other than ACTH had normal levels. In primary hypothyroidism postmetyrapone 11-deoxycortisol is significantly greater than in normals. This difference is thought to be caused by delayed metabolic clearance of the steroid. Simultaneous measurement of serum cortisol affords an internal ...

The adrenal glands, ovaries, testes, and placenta produce steroid hormones, which can be subdivided into 3 major groups: mineral corticoids, glucocorticoids, and sex steroids. Synthesis proceeds from cholesterol along 3 parallel pathways, corresponding to these 3 major groups of steroids, through successive side-chain cleavage and hydroxylation reactions. At various levels of each pathway, intermediate products can move into the respective adjacent pathways via additional, enzymatically catalyzed reactions (see Steroid Pathways in Special Instructions).. 21-Deoxycortisol is an intermediate steroid in the glucocorticoid pathway. While the main substrate flow in glucocorticoid synthesis proceeds from 17-hydroxyprogesterone via 21-hydroxylation to 11-deoxycortisol and then, ultimately, to cortisol, a small proportion of 17-hydroxyprogesterone is also hydroxylated at carbon number 11 by 11-beta-hydroxylase 1 (CYP11B1), yielding 21-deoxycortisol. This in turn can also serve as a substrate for ...
11-Deoxycortisol, also known as cortodoxone (INN) or cortexolone, as well as 17α,21-dihydroxyprogesterone or 17α,21-dihydroxypregn-4-ene-3,20-dione,[1] is a glucocorticoid steroid hormone. It was first synthesized by Tadeusz Reichstein, and has also been referred to as Reichsteins Substance.[1] On April 5, 1952, biochemist Durey Peterson and microbiologist Herbert Murray at Upjohn published the first report of a breakthrough fermentation process for the microbial 11α-oxygenation of steroids (e.g. progesterone) in a single step by common molds of the order Mucorales.[2] 11α-oxygenation of Compound S produces 11α-hydrocortisone, which can be chemically oxidized to cortisone, or converted by further chemical steps to 11β-hydrocortisone (cortisol). 11-Deoxycortisol acts as a glucocorticoid, though is less potent than cortisol. It can be synthesized from 17α-hydroxyprogesterone. In 11β-hydroxylase deficiency, 11-deoxycortisol levels increase dramatically, causing hypertension (as opposed to ...
A new drug formulation of the adrenal cortex (AC) inhibitor o,p′-DDD (chloditan) was developed as a solution for i.v. injection. Its effects on glucocorticoid hormone production by human AC tissue culture and AC function in dogs were studied. A concentration range of 0.005 - 5.0 mg/mL was established by adding 5% o,p′-DDD solution to the culture medium. Cultivation of specimens of human adrenocortical tissue in the presence of o,p′-DDD solution caused after 24 h a dose-dependent decrease of 11-hydroxycorticosteroid (11-HCS) content by 11.0 - 69.8%. The 11-HCS content in dog blood plasma decreased by an average of 3.5 times; the response to synthetic 1 - 24-corticotropin stimulation, by three times, with daily administration for 3 d of 10 mL of the solution. The 11-HCS blood level was still reduced two weeks after withdrawal of the drug. The proposed o,p′-DDD solution showed adrenocorticolytic activity and could be recommended for clinical trials.

Objective: To discover the value of low-dose (LDAT) and standard-dose ACTH tests (SDAT) as compared with the metyrapone test in the diagnosis of secondary adrenal insufficiency. Patients and Methods: LDAT (0.5 mug/m(2)), SDAT (250 mug/m2) and overnight metyrapone (30 mg/kg) tests were carried out in 29 patients with suspected adrenal insufficiency. LDAT and SDAT were also performed in 36 control subjects. Results: 18 of 29 patients were grouped in the adrenal-sufficient (AS) group and 11 of 29 patients in the adrenal-deficient (AD) group according to the metyrapone test results. The control group had significantly higher cortisol responses than the AS and AD groups during LDAT. The control group had similar cortisol responses to the AS group but higher cortisol responses than the AD group during SDAT. The AS group was divided into 2 subgroups: AS patients with multiple pituitary hormone deficiencies (AS-multiple) and AS patients with idiopathic growth hormone deficiencies (AS-isolated). The ...
Natural antioxidants and plant-derived compounds provide a strong defense against cellular damage caused by free-radical induced oxidative stress [16, 17]. Free-radicals and various reactive oxygen species are produced during cellular metabolism in all living systems and are responsible for oxidative cellular damage in human beings. To reduce this damage, some sort of defense mechanism is needed, and indeed, several types of natural and artificial antioxidants are used to control oxidative stress. In particular, plant-derived compounds are a potent source of novel antioxidant activity [18]. Bibenzyl derivatives isolated from D. moniliforme were examined for their antioxidant capacity using DPPH free-radical scavenging assay [11, 13, 14], a popular tool because of its simplicity and high sensitivity. This assay works on the principle that any hydrogen donor is an antioxidant. Thus, a compounds antioxidant effect is proportional to the disappearance of DPPH radicals in test samples [19].. The ...

Surgical stress is the systemic response to surgical injury and is characterized by activation of the sympathetic nervous system, endocrine responses as well as immunological and haematological changes. Measurement of surgical stress is used in anaesthesia, physiology and surgery. Analysis of the surgical stress response can be used for evaluation of surgical techniques and comparisons of different anaesthetic protocols. Moreover they can be performed both in the intraoperative or postoperative period. If there is a choice between different techniques for a surgical procedure, one method to evaluate and compare the surgical techniques is to subject one group of patients to one technique, and the other group of patients to another technique, after which the surgical stress responses triggered by the procedures are compared. The technique with the least surgical stress response is considered the best for the patient. Similarly, a group of patients can be subjected to a surgical procedure where one ...

Cushings syndrome is considered to be a rare disorder that results from prolonged exposure to glucocorticoids. However, there are few epidemiological studies to provide adequate data to describe the incidence and prevalence of the condition accurately. Most cases are diagnosed between the ages of 20 and 50, although any individual may be affected at any age.
Shares of Corcept Therapeutics Inc. soared 57 percent in extended trade Friday, after the U.S. Food and Drug Administration approved Korlym as the first therapy to treat high blood sugar in adults suffering from a hormonal disorder called endogenous Cushings syndrome.

Children with Cushings syndrome are at risk of developing new autoimmune and related disorders after being cured of the disease, a new study shows. The study, Incidence of Autoimmune and Related Disorders After Resolution of Endogenous Cushing Syndrome in Children, was published in Hormone and Metabolic Research. Patients with Cushings syndrome have excess levels of the hormone cortisol, a corticosteroid that inhibits the effects of the immune system. As a result, these patients are protected from autoimmune and related diseases. But it is not known if the risk rises after their ...

Specifically, Barnaby has been studying the growth of kinetin-based nanostructures and the growth of selenium nanoparticles as biocompatible materials for drug delivery for prevention of oxidative cellular damage. She has been examining the potential of these materials as radical scavengers and investigating their efficiency as supports for enzymes such as glutathione peroxidase, which plays a vital role in prevention of oxidative damage. These materials have been found to survive in live cell cultures of normal rat kidney cells, which is promising and she hopes that she will be soon be moving on to conduct in vivo studies. She has already presented at conferences such as the New York American Chemical Society undergraduate research symposium, the Columbia University undergraduate research symposium, the Fordham undergraduate research symposium, and ECSC, which involved undergraduate participants from colleges and universities all over the East Coast ...

To examine the production of steroids with potential oocyte maturation-inducing or pheromonal activity in the goldfish (Carassius auratus) we have incubated mature ovaries of this species with 17-[3H]hydroxyprogesterone. The metabolites in the unconjugated, glucuronide, and sulfate fractions were identified by chromatography, microchemical reaction, and, in most cases, crystallization to constant specific activity. A major metabolite, present in all three fractions, was tentatively identified as 5 alpha-pregnane-3 beta,7 alpha,17,20 beta-tetrol. Although 17,20 beta-dihydroxy-4-pregnen-3-one (17,20 beta-P) was found in only low yield (as a sulfate), the presence of the tetrol indicates that it is synthesized in high yield but very rapidly metabolized. The relative proportions of 17,20 alpha-dihydroxy-4-pregnen-3-one (17,20 alpha-P), 11-deoxycortisol (17,21-dihydroxy-4-pregnen-3,20-dione) and 17,20 beta,21-trihydroxy-4-pregnen-3-one (17,20 beta,21-P) varied significantly between incubations and ...
This drug was approved for use in patients with endogenous Cushings syndrome who have type 2 diabetes or glucose intolerance and are not candidates for surgery or who have not responded to prior surgery. Korlym should never be used (contraindicated) by pregnant women.. Prior to FDAs approval of Korlym, there were no approved medical therapies for the treatment of endogenous Cushings syndrome.. Endogenous Cushings syndrome is a serious, debilitating and rare multisystem disorder. It is caused by the overproduction of cortisol (a steroid hormone that increases blood sugar levels) by the adrenal glands. This syndrome most commonly affects adults between the ages of 25 and 40. About 5,000 patients will be eligible for Korlym treatment, which received an orphan drug designation by the FDA in 2007.. Korlym blocks the binding of cortisol to its receptor. It does not decrease cortisol production but reduces the effects of excess cortisol, such as high blood sugar levels.. The safety and efficacy of ...

Just like that money from the UFOs, the IMF funds will only be a stop gap measure and will not address the fundamental problem of the inadequate economic structure - in simple terms, we spend way more than we earn. While we are benefiting from the IMF flows, it is necessary to continue the fundamental reform of our economic structure, as failure to do this will only see us in a more desperate situation at the end of the three to five-year period that we may get the IMF facility for. Unless we make a paradigm shift in our fundamental production and consumption relationships, we will face more suffering at the end of the IMF facility, and then the emotional ones amongst us will say, see, I told you the IMF was the wrong way to go, not fully understanding that it would have been our own actions (or inactions) that would continue to cause our suffering ...
