Examinations that evaluate and monitor hormone production in the adrenal cortex.
The outer layer of the adrenal gland. It is derived from MESODERM and comprised of three zones (outer ZONA GLOMERULOSA, middle ZONA FASCICULATA, and inner ZONA RETICULARIS) with each producing various steroids preferentially, such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and ANDROSTENEDIONE. Adrenal cortex function is regulated by pituitary ADRENOCORTICOTROPIN.
The rostral part of the frontal lobe, bounded by the inferior precentral fissure in humans, which receives projection fibers from the MEDIODORSAL NUCLEUS OF THE THALAMUS. The prefrontal cortex receives afferent fibers from numerous structures of the DIENCEPHALON; MESENCEPHALON; and LIMBIC SYSTEM as well as cortical afferents of visual, auditory, and somatic origin.
A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.

Blood tests that are used to evaluate how well a patient's liver is working and also to help diagnose liver conditions.
The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.
The inner zone of the adrenal cortex. This zone produces the enzymes that convert PREGNENOLONE, a 21-carbon steroid, to 19-carbon steroids (DEHYDROEPIANDROSTERONE; and ANDROSTENEDIONE) via 17-ALPHA-HYDROXYPREGNENOLONE.
Pathological processes of the ADRENAL CORTEX.

Measurement of the various processes involved in the act of respiration: inspiration, expiration, oxygen and carbon dioxide exchange, lung volume and compliance, etc.
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).
The wide middle zone of the adrenal cortex. This zone produces a series of enzymes that convert PREGNENOLONE to cortisol (HYDROCORTISONE) via 17-ALPHA-HYDROXYPROGESTERONE.

Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.
An adrenal disease characterized by the progressive destruction of the ADRENAL CORTEX, resulting in insufficient production of ALDOSTERONE and HYDROCORTISONE. Clinical symptoms include ANOREXIA; NAUSEA; WEIGHT LOSS; MUSCLE WEAKNESS; and HYPERPIGMENTATION of the SKIN due to increase in circulating levels of ACTH precursor hormone which stimulates MELANOCYTES.
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.
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 synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of ADRENOCORTICOTROPIC HORMONE. ACTH (1-24), a segment similar in all species, contains the biological activity that stimulates production of CORTICOSTEROIDS in the ADRENAL CORTEX.

A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.
A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.
A condition caused by the excessive secretion of ANDROGENS from the ADRENAL CORTEX; the OVARIES; or the TESTES. The clinical significance in males is negligible. In women, the common manifestations are HIRSUTISM and VIRILISM as seen in patients with POLYCYSTIC OVARY SYNDROME and ADRENOCORTICAL HYPERFUNCTION.
Abnormally infrequent menstruation.
A condition observed in WOMEN and CHILDREN when there is excess coarse body hair of an adult male distribution pattern, such as facial and chest areas. It is the result of elevated ANDROGENS from the OVARIES, the ADRENAL GLANDS, or exogenous sources. The concept does not include HYPERTRICHOSIS, which is an androgen-independent excessive hair growth.
Diminished or absent ability of a female to achieve conception.
The induction of local hyperthermia by either short radio waves or high-frequency sound waves.
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.

In a typical game, decision-making "players," who each have their own goals, try to gain advantage over the other parties by anticipating each other's decisions; the game is finally resolved as a consequence of the players' decisions.
A stage of development at which the ADRENAL GLANDS undergo maturation leading to the capability of producing increasing amounts of adrenal androgens, DEHYDROEPIANDROSTERONE and ANDROSTENEDIONE. Adrenarche usually begins at about 7 or 8 years of age before the signs of PUBERTY and continues throughout puberty.
Development of SEXUAL MATURATION in boys and girls at a chronological age that is 2.5 standard deviations below the mean age at onset of PUBERTY in the population. This early maturation of the hypothalamic-pituitary-gonadal axis results in sexual precocity, elevated serum levels of GONADOTROPINS and GONADAL STEROID HORMONES such as ESTRADIOL and TESTOSTERONE.
An enzyme that catalyzes the reduction of a 3 beta-hydroxy-delta(5)-steroid to 3-oxo-delta(4)-steroid in the presence of NAD. It converts pregnenolone to progesterone and dehydroepiandrosterone to androstenedione. EC 1.1.1.145.

INFLAMMATION of the LIVER.
Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cirrhosis involves the destruction of small intra-hepatic bile ducts and bile secretion. Secondary biliary cirrhosis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.

Tests of adrenal insufficiency. (1/61)

AIM: In suspected adrenal insufficiency, the ideal test for assessing the hypothalamo-pituitary-adrenal axis is controversial. Therefore, three tests were compared in patients presenting with symptoms suggestive of adrenal insufficiency. METHOD: Responses to the standard short Synacthen test (SSST), the low dose Synacthen test (LDST), and the 08:00 hour serum cortisol concentration were measured in 32 patients. A normal response to the synacthen test was defined as a peak serum cortisol of >/= 500 nmol/l and/or incremental concentration of >/= 200 nmol/l. The sensitivity and specificity of the 08:00 hour serum cortisol concentration compared with other tests was calculated. RESULTS: Three patients had neither an adequate peak nor increment after the SSST and LDST. All had a serum 08:00 hour cortisol concentration of < 200 nmol/l. Eight patients had abnormal responses by both criteria to the LDST but had normal responses to the SSST. Three reported amelioration of their symptoms on hydrocortisone replacement. Twenty one patients had a normal response to both tests (of these, 14 achieved adequate peak and increment after both tests and seven did not have an adequate peak after the LDST but had a normal increment). The lowest 08:00 hour serum cortisol concentration above which patients achieved normal responses to both the LDST and SSST was 500 nmol/l. At this cut off value (compared with the LDST), the serum 08:00 hour cortisol concentration had a sensitivity of 100% but specificity was only 33%. CONCLUSION: The LDST revealed mild degrees of adrenal insufficiency not detected by the SSST. The value of a single 08:00 hour serum cortisol concentration is limited.  (+info)

Effect of multiple courses of antenatal corticosteroids on pituitary-adrenal function in preterm infants. (2/61)

AIM: To evaluate the pituitary-adrenal function of preterm infants whose mothers received multiple courses (8 or more doses) of antenatal dexamethasone. METHODS: The pituitary-adrenal function of 14 preterm infants whose mothers received eight or more doses of antenatal dexamethasone were assessed using the human corticotrophin releasing hormone (hCRH) stimulation test when 7 days (n = 14) and 14 days old (n = 12). During each test, blood samples were taken at 0 (baseline), 15, 30 and 60 minutes after an intravenous bolus dose of hCRH (1 microg/kg). The corresponding hormone concentrations were compared between days 7 and 14, and with various associated factors. RESULTS: The baseline (0 min) plasma adrenocorticotrophic hormone concentration was significantly higher at day 14 than at day 7 (p = 0.036). None of the corresponding poststimulation (15, 30, and 60 min) hormone concentrations was significantly different between the two time epochs. When the association between the hormone concentrations and the number of antenatal dexamethasone doses received by the mothers was assessed, a significant negative correlation was observed in serum cortisol concentrations at 15 and 30 min on day 14 (r = -0.59, p = 0.04 and r = -0.60, p = 0.039, respectively). CONCLUSIONS: The absence of a significant difference in poststimulation hormone concentrations between days 7 and 14 in this cohort of infants, and the similarity of their hormone responses with those of older children and adults, suggests that no severe pituitary-adrenal suppression had occurred. None the less there was evidence of mild adrenal suppression in some of the treated infants. Vigilance in monitoring blood pressure, electrolytes and signs of adrenal suppression in infants whose mothers receive multiple courses (8 or more doses) of antenatal dexamethasone is required, as some of them might have diminished adrenal reserve.  (+info)

Adrenal insufficiency in septic shock. (3/61)

BACKGROUND: Functional adrenal insufficiency has been documented in critically ill adults. OBJECTIVE: To document the incidence of adrenal insufficiency in children with septic shock, and to evaluate its effect on catecholamine requirements, duration of intensive care, and mortality. SETTING: Sixteen-bed paediatric intensive care unit in a university hospital. METHODS: Thirty three children with septic shock were enrolled. Adrenal function was assessed by the maximum cortisol response after synthetic adrenocorticotropin stimulation (short Synacthen test). Insufficiency was defined as a post-Synacthen cortisol increment < 200 nmol/l. RESULTS: Overall mortality was 33%. The incidence of adrenal insufficiency was 52% and children with adrenal insufficiency were significantly older and tended to have higher paediatric risk of mortality scores. They also required higher dose vasopressors for haemodynamic stability. In the survivor group, those with adrenal insufficiency needed a longer period of inotropic support than those with normal function (median, 3 v 2 days), but there was no significant difference in duration of ventilation (median, 4 days for each group) or length of stay (median, 5 v 4 days). Mortality was not significantly greater in children with adrenal insufficiency than in those with adequate adrenal function (6 of 17 v 5 of 16, respectively). CONCLUSION: Adrenal insufficiency is common in children with septic shock. It is associated with an increased vasopressor requirement and duration of shock.  (+info)

Expression of adrenocorticotropin receptor gene in adrenocortical adenomas from patients with Cushing syndrome: possible contribution for the autonomous production of cortisol. (4/61)

OBJECTIVE: To examine whether inhibition of endogenous adrenocorticotropin (ACTH) secretion in patients with Cushing syndrome affects the expression of the ACTH receptor (ACTH-R) gene in adrenocortical adenoma and attached atrophic normal gland. SUMMARY BACKGROUND DATA: ACTH increases adrenal cell growth and steroidogenesis by means of ACTH-R. In vivo and in vitro studies have shown that expression of ACTH-R is upregulated by its own ligand ACTH in several species. In patients with Cushing syndrome resulting from adrenocortical adenoma, there is autonomous production of cortisol from the adenoma. This strongly inhibits endogenous ACTH secretion, giving rise to the speculation that the expression of the ACTH-R gene in these patients is also suppressed. However, previous studies have shown that administration of exogenous ACTH to these patients leads to a further increase in the production of cortisol, suggesting the expression of functional ACTH-R in the adenoma. The authors, therefore, examined the expression of the ACTH-R gene in these patients. METHODS: Fourteen patients with Cushing syndrome were studied. Glucocorticoid excess resulting from autonomous production from the adenomas was ascertained, and unilateral adrenalectomy was performed. The levels of ACTH-R and cytochrome P450 side chain cleavage enzyme (P450scc) mRNAs were determined by Northern blot analysis. The entire coding region of the ACTH-R gene in these patients was sequenced. RESULTS: ACTH-R mRNA abundance in the attached atrophic normal adrenals was suppressed and invariably less than that in the normal gland obtained from a patient with renal cancer. However, the expression of ACTH-R mRNA was not suppressed in any of the adenomas. Expression of ACTH-R mRNA in the adenomas was four- to sixfold greater than that in the attached atrophic gland. No mutation in the coding sequence of the ACTH-R gene in the adenoma was detected in any of the patients. The mRNA in the adenomas appeared to be translated into functionally active receptor because intramuscular administration of ACTH resulted in significant increases in plasma cortisol before surgery but not 3 months after surgery. In addition, there was a positive linear correlation between the expressions of ACTH-R and P450scc mRNAs in the adenoma tissue. CONCLUSIONS: Suppressed ACTH secretion in patients with Cushing syndrome results in reduction of the ACTH-R mRNA expression in nonneoplastic adrenocortical cells. However, the regulatory mechanism of ACTH-R expression might be different in adenoma. Persistent expression in the adenoma of ACTH-R alone, even in the absence of ACTH, might result in increased basal adenyl cyclase activity, as observed in the case of thyroid-stimulating hormone receptor, and thereby might play a role in the autonomous production of cortisol.  (+info)

Effect on adrenal function of topically applied clobetasol propionate (Dermovate). (5/61)

Thirty-nine patients (15 outpatients and 24 inpatients) with a variety of skin diseases affecting variable areas of the body surface were treated with clobetasol propionate ointment (Dermovate). Before and after treatment the adrenal response to an intramuscular injection of tetracosactrin was rested and additional 9 am plasma cortisol levels were measured at intervals during treatment. A satisfactory initial therapeutic response was achieved in almost all cases during the trial period. When more than 50 g of ointment a week was used a significant number of patients developed adrenal suppression. WHen less than 50 g per week was used any suppression tended to be transtion. These cysts may be the cause of this condition, producing abnormal amounts of ovarian steroids which modify the pituitary response. Futher studies are needed, however, to determine this possibility.  (+info)

Evaluation and management of adrenal masses. (6/61)

BACKGROUND: The widespread use of abdominal imaging has led to increased detection of adrenal tumors. The significance of these masses, as well as the optimal management approach to treatment, has generated some controversy regarding further evaluation and therapy. METHODS: The authors reviewed the literature regarding the evaluation and management of these masses, particularly adrenal incidentalomas. Based on their institutional experience, they propose a diagnostic, evaluation, and management algorithm for treating adrenal masses. RESULTS: Appearance and clinical history should indicate how to perform the biochemical evaluation, keeping in mind that the presence of pheochromocytomas must be ruled out. Radiological evaluation by CT or MRI provides useful parameters to identify malignant lesions. Surgery is indicated for masses that are larger than 5 cm in diameter or suspected of malignancy. Fine-needle aspiration biopsy should be used when other extra-adrenal malignancies are suspected and after pheochromocytoma has been ruled out. CONCLUSIONS: Careful analysis of each adrenal mass is essential to effectively avoid potential problems. Guidelines to manage patients with adrenal masses are needed.  (+info)

Evaluation of low dose ACTH stimulation test in suspected secondary adrenocortical insufficiency. (7/61)

BACKGROUND: Several studies in the last few years have shown that the standard 250 micro g dose used in ACTH stimulation test may be very high and have suggested that a dose of 1 micro g may be sufficient for evaluating hypothalamo-pituitary adrenal (HPA) axis. AIMS: To evaluate the role of low dose ACTH stimulation test in patients with suspected Secondary Adrenal Insufficiency (SAI). SUBJECTS AND METHODS: Thirty-one patients of suspected SAI with a documented pituitary lesion and seven normal healthy controls were included in the study. All the subjects underwent ACTH stimulation test with standard high dose (HD= 250 microg) and low dose (LD= 1 microg) ACTH. Insulin Induced Hypoglycaemia (IIH) test was done in 7 out of 9 patients in whom the results of the two tests were discordant. The cut off for normal HD stimulation test was taken as peak cortisol response > 18 microg/dl and for LD test, either a cortisol response of > 18 microg/dl or an increment of more than 7 micro g/dl over the basal value at any time during the test, on the basis of response observed in controls. RESULTS: 22/31 patients (74%) in SAI group showed concordant results with both tests, whereas nine patients had discordant results. These nine patients showed AI with LD ACTH, but HD ACTH test showed a normal response. In 7 of these 9 patients who underwent IIH, AI was confirmed in 6. CONCLUSION: The LD ACTH stimulation test seems to be better than HD ACTH stimulation test for evaluating HPA axis in patients with suspected SAI. When basal cortisol is normal, LD ACTH stimulation test detects subtle SAI.  (+info)

Prospective examination of adrenocortical function in advanced AIDS patients. (8/61)

In human immunodeficiency virus infected individuals, human cytomegalovirus (CMV) remains a significant pathogen. The adrenal gland is a preferential site of CMV disease in acquired immunodeficiency syndrome (AIDS) patients. However, glucocorticoid replacement is often not selected because of the risk of exacerbating underlying infection. To evaluate the need for glucocorticoid replacement in these patients, we performed a prospective study to investigate the adrenal function in 60 advanced AIDS patients. Their adrenal function including rapid ACTH test (RAT), basal plasma ACTH level, and daily urinary free cortisol level was evaluated. Approximately 25% of the patients turned out to be abnormal in this evaluation. Almost 60% of the patients could be followed up for one year or until their death. Using the follow-up data, we calculated sensitivity, specificity, positive predictive value and negative predictive value. Excretion of urinary free cortisol with normal RAT was comparable to normal controls, whereas patients with abnormal RAT excreted significantly lower urinary free cortisol. During hospitalization, 14 patients with normal RAT had febrile episode. During the febrile period the concentration of the urinary free cortisol level increased by 2.2 times. This study suggests that glucocorticoid replacement is necessary for AIDS patients suspected as clinically adrenal insufficiency, and that the dose of glucocorticoid replacement might be increased during sick days in AIDS patients with abnormal adrenal function.  (+info)

The human CRH test (hCRH test) is used to differentiate Cushings disease (CD) from ectopic ACTH secretion (EAS); to assess autonomous cortisol secretion by the adrenal glands; to characterize pseudo-Cushings syndrome (CS) or adrenal insufficiency (AI).We measured ACTH and cortisol levels; we collected the peak values (peak ACTH and peak cortisol), and calculated the percentage increases (∆% ACTH and ∆% cortisol) after an iv. bolus of 100 μg hCRH.cross-sectional study of using hCRH tests from 2010 to 2019.Referral University-Hospital center.We enrolled 200 patients: 86 CD, 15 EAS, 18 adrenal CS, 25 mild adrenal autonomous cortisol secretion, 31 pseudo-CS, 25 suspected AI.to assess the diagnostic accuracy of hCRH test.The hCRH test was performed mainly for the differential diagnosis of ACTH-dependent CS or adrenal lesions (p=0.048). Peak ACTH and peak cortisol were higher in CD, and ∆% ACTH and ∆% cortisol were able to differentiate CD from EAS with a sensitivity and specificity ,80%. ...
One of the worst things we can do as we try to learn to deal with stress is to fail to recognize it for what it is. It is easy to simply point at everything in our lives that we deem frustrating and call them stress. But are those situations and events really stress, or merely what they appear to be: situations and events?. After all, what frustrates you might seem perfectly harmless to me, and vice versa. Given that observation, the reality is that those situations and events that we tend to refer to as stress are nothing more than potential stressors - outside stimuli that may or may not incite our internal stress responses. In other words, it is not what is happening around us that causes stress, but our subconscious response to those factors that ultimately determines whether or not the stress response is activated.. Thats where the brain comes into play. It is the brain that works to identify and categorize an untold number of outside stimuli every moment of every day. Some of these ...

In Europe, the prevalence and incidence of chronic primary AI are 93 to 144 cases per million and 4.4 to 6.0 new cases per million population per year, respectively [1,4,14,15]. Central AI is more common than primary AI. Secondary AI has an estimated prevalence of 150 to 280 cases per million [1,4,16,17,18,19,20]. Tertiary AI is believed to be the most common form of AI [1,4,21]. Among the patients who underwent a rapid ACTH stimulation test or an insulin tolerance test to rule out AI in our study, approximately one-fourth were actually diagnosed with AI, and all these patients had central AI. No cases of primary AI were found in our cohort. The prevalence and incidence of primary AI in Korea have not yet been reported [22]. Thus, the lack of cases of primary AI in our study either reflects a lower prevalence of primary AI in Korea than in other countries, or is the result of limitations placed on determining which patients were eligible for an ACTH stimulation or insulin tolerance test.

The first step is to check the basal cortisol secretion. In normal subjects serum cortisol levels peak around 6-8 AM with the normal range between 8 and 20mcg/dl. Although morning cortisol is not a reliable indicator of AI, based on current published data, AM cortisol levels less then 3 mcg/dl provide clear evidence that the patient has adrenal insufficiency while a value above 15mcg/dL virtually excludes the diagnosis. A salivary cortisol level is another screening method, but it is less commonly used and has different cutoff values.. In the second step, a Cosyntropin stimulation test is performed to assess adrenocortical reserve. The test can be performed at any time of the day and consists of intramuscular administration of 250mcg of synthetic human ACTH (Cosyntropin). Thirty to 60 minutes following ...

N2 - We sought to determine the effects of aging on several aspects of adrenal steroidogenesis in the hopes of characterizing the possible causes of adrenal androgen deficiency in elderly women. To this end, we quantified basal morning concentrations of cortisol (F), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DS), and androstenedione (A4) and then evaluated the effects of overnight dexamethasone (DEX) suppression followed by adrenal responses to graded hourly infusions of ACTH, ranging from 20 -1280 ng/1.5 m2·h. Finally, we performed a standard 0.25-mg ACTH bolus stimulation test, with ...

Adrenal Function in Adults: Four clinical pharmacology studies have been conducted in humans to assess the effect of NASONEX at various doses on adrenal function. In one study, daily doses of 200 and 400 mcg of NASONEX and 10 mg of prednisone were compared to placebo in 64 patients (22 to 44 years of age) with allergic rhinitis. Adrenal function before and after 36 consecutive days of treatment was assessed by measuring plasma cortisol levels following a 6-hour Cortrosyn (ACTH) infusion and by measuring 24-hour urinary free cortisol levels. NASONEX at both the 200- and 400-mcg dose, was not associated with a statistically significant decrease in mean plasma cortisol levels post-Cortrosyn infusion or a statistically significant decrease in the 24-hour urinary free cortisol levels compared to placebo. A statistically significant decrease in the mean plasma cortisol levels post-Cortrosyn infusion and 24-hour urinary free cortisol levels was detected in the prednisone treatment group compared to ...
Background:. High dose inhaled steroids can lead to adrenal suppression. It is not clear how the use of other steroids (nasal, topical or oral) in addition to inhaled steroids, affect adrenal suppression.. Aims. The aim of this study was to review past synacthen tests and try to determine steroid risk factors for those with suppressed cortisol.. Methods. A review of synacthen tests done over a 3 year period on patients with asthma was carried out. Data extracted and determined included age; BMI sd; calculated surface area, beclometasone equivalent steroid dose, oral steroid intake, other steroids (nasal, topical), and result of synacthen test.. Results. 19 synacthen tests were available for analysis. The average age was 11.3 years (range 4.6-16.2). 10 were boys. 6 patients were on doses of inhaled corticosteroids not recommended in the British National Formulary for Children (BNFc), and 3 of these had adrenal suppression. Of the remaining 13 patients only 2 had adrenal suppression. Only 2 ...

Measurement of 24-h urinary free cortisol (UFC) provides the most sensitive and specific diagnostic information for adrenal malfunctions, especially for Cushing syndrome (1)(2). The existing methodologies include immunoassays (3)(4)(5) and HPLC, with and without solid-phase extraction and derivatization (6)(7). Immunoassays for UFC are precise but overestimate the concentration because of antibodies cross-reactivity with various metabolites and with synthetic corticoids having a chemical configuration similar to that of cortisol (8). HPLCs, on the other hand, although very specific, require large volumes of mobile phase, as well as sample pretreatment. Capillary electrophoresis (CE) overcomes many of these problems through the use of an open-tubular format, thus avoiding interaction of analytes with the solid-phase resin. Earlier, we reported the feasibility of rapid UFC detection in solid-phase extraction CE with a neutral capillary (9). Using a neutral capillary, we could demonstrate a ...
This study proposes to provide the reference range of cortisol results when the ACTH stimulation test is done under stressful conditions. This important information is currently not available in the literature. To achieve this, we will perform the ACTH stimulation test in a cohort of patients who are booked for elective surgery. By choosing elective surgery patients, we afford ourselves the opportunity of performing the test once before surgery. The test is then repeated within 12 hours of surgery. The first test will be done on an out-patient basis under usual conditions (minimal stress) while the second will be done under intense physical stress. The 2 sets of results will be compared and the effect of stress on test results will be determined. For the sake of uniformity, we have chosen patients who are booked to undergo repair of an abdominal aortic aneurysm (AAA) as our study cohort.. The ACTH stimulation is an important test that suffers from limitations resulting from lack of clear ...

When I was given the chance to test Thrivas new female hormone test I jumped at the chance. My hormonal history is, colourful, shall we say.. As I mentioned I didnt have periods for years due to low body weight. I was also on a strong birth control pill for acne for too long during my teens. I dont think the guidelines around it were clear enough back then (were talking nearly 20 years ago) and manipulating my bodys own hormonal rhythm for that long, in hindsight, wasnt great, or so a reproductive endocrinologist (fertility doctor) once told me. The acne in the first place could have been a sign of issues, however common that is in teenagers.. I got pregnant eventually despite no periods (so clearly something was happening inside), but regular periods didnt return until after Id finished breastfeeding my second child, at the age of 32! Now theyre every 2 months ish, not painful like they were in my teens, but incredibly heavy (sorry for the TMI but its relevant right?).. Plus ...
