Each adrenal consists of two functionally distinct endocrine glands: the cortex, derived from mesenchymal cells, and the medulla, derived from neuroectodermal cells. Glucocorticoid insufficiency can be primary, resulting from the direct insult to the adrenal cortex, or secondary, from adrenocorticotropic hormone (ACTH) or corticotropin-releasing hormone (CRH) hyposecretion as a result of pituitary or hypothalamic dysfunctions.
Primary adrenal insufficiency affects glucocorticoid and mineralocorticoid secretion and may be fatal if untreated.
Secondary and tertiary adrenal insufficiencies occur commonly after the discontinuation of glucocorticoids.
All patients with primary adrenal insufficiency complain of fatigue, anorexia, and weight loss.
Evaluating a patient with suspected adrenal insufficiency is a three-step process: establishing the diagnosis, differentiating between primary and secondary adrenal insufficiencies, and looking for the cause of adrenal insufficiency.
These patients should be further evaluated by the cosyntropin (Cortrosyn) stimulation test (CST), which can be performed at any time during the day. The insulin tolerance test (ITT) and metyrapone test are generally used for the evaluation of patients suspected to have secondary adrenal insufficiency.
Patients with Addison’s disease require lifelong replacement with glucocorticoids and mineralocorticoids.
Acute adrenal insufficiency (adrenal crisis) is a life-threatening emergency, which usually manifests with nausea, vomiting, abdominal pain, and shock. The overall incidence of AI in critically ill patients is less than 10%, but an incidence as high as 50% in a patient with septic shock has been reported. Intensive care unit (ICU) patients with hemodynamic instability, despite fluid resuscitation (especially in the presence of shock), should be tested for AI. More than 90% of circulating cortisol is bound to cortisol- binding globulin (CBG) and albumin.
Hydrocortisone, 50 mg IV every 6 to 8 hours is an adequate replacement dose for critically ill patients with suspected adrenal insufficiency.
Autoimmune destruction of the adrenal glands is the most common cause of primary adrenal insufficiency in the United States. Almost all patients with primary adrenal insufficiency present with fatigue, anorexia, and weight loss. Primary and secondary adrenal insufficiencies are differentiated through measurement of the plasma ACTH level. Acute adrenal insufficiency is a medical emergency that should be treated with IV hydrocortisone and fluids as soon as the diagnosis is suspected. Adrenal insufficiency should be suspected in critically ill patients with septic shock or hypotension refractory to intravenous fluids and pressors. Diseases related to adrenal hyperfunction are relatively rare, but they have significant mortality and morbidity if untreated. Cushing’s syndrome (CS) is composed of symptoms and signs associated with prolonged exposure to inappropriately high levels of plasma glucocorticoids.
Harvey Cushing initially described the clinical features of CS in the early 20th century, including centripetal obesity, moon face, hirsutism, and plethora; however, such a classic clinical picture is not always present and a high index of suspicion is usually required.
Patients with ectopic ACTH syndrome caused by small cell lung carcinoma lack many of the typical clinical features.
Screening for CS may be done by a 24-hour urinary free cortisol (UFC) determination, 1-mg dexamethasone suppression test (DST), or midnight salivary cortisol test (Fig. The 1-mg DST is performed by the administration of dexamethasone, 1 mg at 11 pm, followed by measurement of the plasma cortisol level at 8 am. The combined DST-CRH stimulation test may be used for differentiating between CS and pseudo-Cushing’s syndrome. Certain drugs, such as phenytoin, phenobarbitals, and rifampin, increase the clearance rate of dexamethasone, resulting in false- positive results during a DST. Because of the challenging nature of CS, reaching the proper diagnosis requires a stepwise evaluation, knowledge of the limitations of each test, and avoidance of shortcuts (see Fig.
Once Cushing’s syndrome is biochemically confirmed, the plasma ACTH level should be measured, preferably in the morning. A combination of the CRH stimulation test and an overnight high-dose DST are used to differentiate ectopic CS from Cushing’s disease. Surgical (trans-sphenoidal) removal of the ACTH-secreting pituitary tumor is the treatment of choice. Cushing’s syndrome caused by an adrenal adenoma is usually cured by laparoscopic unilateral adrenalectomy. Evaluation for the plasma circadian rhythm, midnight plasma cortisol level, 2-day low-dose dexamethasone suppression test (LDDST), and combined LDDST-CRH test were described by the workshop as second-line screening tests. Screening for Cushing’s syndrome may be done by a midnight salivary cortisol level assay, 1-mg DST, or 24-hour urinary free cortisol test. Certain drugs, such as phenytoin, phenobarbitals and rifampin, increase the clearance rate of dexamethasone, resulting in false-positive results during DSTs. Because of the challenging nature of Cushing’s syndrome, obtaining a proper diagnosis requires a stepwise evaluation, knowledge of the limitations of each test, and avoidance of shortcuts. Once Cushing’s syndrome has been biochemically confirmed, the plasma ACTH level should be measured to differentiate between ACTH-dependent and ACTH-independent CS.
Conn first described primary hyperaldosteronism in 1955 in a patient with an adrenal adenoma. Two forms of familial hyperaldosteronism (FH) have been described: FH type I and FH type II.
The clinical picture varies from asymptomatic to symptoms related to hypertension, hypokalemia, or both. The workup of a patient for primary hyperaldosteronism involves the following steps: screening tests for primary hyperaldosteronism, establishing the autonomy of aldosterone secretion, and determination of the source of hyperaldosteronism (Fig. Although hypokalemia in a hypertensive patient is suggestive of hyperaldosteronism, normokalemia does not exclude the diagnosis. IV administration of 2 L of isotonic saline over 4 hours in the recumbent patient is a less favored way to establish the diagnosis.
The treatment goals are to reduce the morbidity and mortality associated with hypertension, hypokalemia, and cardiovascular damage by normalization of blood pressure and aldosterone levels.
Medical treatment is reserved for patients with IHA or those with APAs who are poor surgical candidates.
For the first few weeks after surgery, patients should increase their salt intake to compensate for hypoaldosteronism that may occur because of chronic suppression of the renin-angiotensin system.
Spironolactone and eplerenone should be discontinued for 6 weeks before biochemical testing and potassium needs to be replaced to the normal range. Familial hyperaldosteronism type I, or glucocorticoid-remediable hyperaldosteronism (GRH), is an autosomal dominant disease in which aldosterone is synthesized in the zona fasciculata of the adrenal gland under the control of ACTH.6 Affected individuals are usually younger than 40 years, exhibit hypertension resistant to standard therapy, and have a family history of primary hyperaldosteronism or a cerebrovascular accident at a young age. There are no consensus statements for the evaluation and therapy of patients with hyperaldosteronism. There is some disagreement about the role of adrenal venous sampling in patients with biochemical proof of hyperaldosteronism. Patients with PHEO may have paroxysmal hypertension (48%) or persistent hypertension (29%), or be normotensive (13%).9 Wide fluctuations in blood pressure and resistance to antihypertensive medications are typical of those with pheochromocytoma. The triad of headaches, palpitations, and diaphoresis suggests the diagnosis of PHEO, but absence of these symptoms does not exclude the disease. Patients with indeterminate levels of plasma-free metanephrines should have their urinary metanephrine and serum catecholamine levels measured (Fig. In patients with nondiagnostic ranges of plasma and urine catecholamine and metanephrine levels, and clinical features suggestive of PHEO, repeating the measurements at the time of symptoms or proceeding with dynamic testing may be used to support or exclude the diagnosis.10 Clonidine normally suppresses plasma catecholamines, a response that is lost in PHEO. The list of medications and interfering substances varies according to what is measured-plasma or urine catecholamines or their metabolites-and to the specific assay used. Chemical shift MRI has a sensitivity of 93% to 100% and specificity of approximately 50% in detecting pheochromocytomas.
Surgery for PHEO has shifted from the open conventional procedure to the laparoscopic approach over the past decade.
The triad of headaches, palpitations, and diaphoresis suggests the diagnosis of pheochromocytoma, but absence of these symptoms do not exclude the disease. Beta blockers should not be used in patients with suspected pheochromocytoma until alpha blockade has been instituted. Plasma-free metanephrines have 99% and 97% sensitivity for sporadic and familial pheochromocytomas, respectively.
Adequate medical preparation is essential and should be initiated at least 10 to 14 days before surgery. In prepubertal children, boys and girls, androgen excess manifests as increased rate of growth in height and skeletal maturation, leading to premature epiphyseal fusion and short adult height. Androgen excess with onset at puberty causes premature skeletal maturation and short adult height in boys.
Of the various causes of adrenal hyperandrogenism, nonclassic (adult-onset) congenital adrenal hyperplasia (CAH), and androgen-producing adrenal tumors are discussed in this section. Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal recessive disorder, with most patients exhibiting a defect in 21-hydoxlyase enzyme activity, resulting in decreased cortisol production. Glucocorticoids, oral contraceptives (OCPs), antiandrogens such as aldactone, or a combination of these medications are used to treat women with NCAH.
Nonclassic congenital adrenal hyperplasia (NCAH) is mostly caused by a defect in the 21-hydroxylase enzyme and manifests as hyperandrogenism in young adolescent and adult women. The main differential diagnosis for NCAH is polycystic ovary syndrome, which is about 40 to 50 times more common.

The adrenal cortex consists of three concentric zones: The outer glomerulosa secretes the mineralocorticoid aldosterone, the intermediate fasciculata secretes cortisol, and the inner reticularis secretes androgens.
Autoimmune destruction of the adrenal glands (Addison’s disease) is the most common cause of primary adrenal insufficiency in United States (70%-90%), whereas tuberculosis is now the second most common cause worldwide.
Less frequently, ACTH deficiency may be caused by pituitary macroadenomas, pituitary surgery or radiation, and parasellar diseases.
Other clinical and laboratory manifestations of primary adrenal insufficiency are presented in Table 1. ITT is considered the gold standard test for the evaluation of hypothalamic-pituitary-adrenal (HPA) axis. The test has not been well validated for the evaluation of adrenal function and its current role in the evaluation of adrenal function is limited to research protocols.
When the biochemical workup is consistent with primary adrenal insufficiency, computed tomography (CT) scanning of the adrenal glands may help with the differential diagnosis. Patients may be previously undiagnosed or have chronic primary adrenal insufficiency, with no or inadequate glucocorticoid replacement.
Diagnostic workup in a patient with no history of AI should include a plasma sample for cortisol and ACTH level determination, immediately followed by an IV bolus of hydrocortisone, 100 mg, and adequate fluid replacement (normal saline). The concept of total adrenal insufficiency has gradually been replaced by relative adrenal insufficiency, which may be fatal in critically ill patients. A random serum cortisol level determination and the standard CST are the two commonly used tests for evaluating adrenal function in these patients.
In the following sections, Cushing’s syndrome, primary hyperaldosteronism, pheochromocytoma, and androgen-producing adrenal tumors are reviewed.


The rapid course and high levels of ACTH and cortisol often result in hyperpigmentation, myopathy, peripheral edema, glucose intolerance, and hypokalemic alkalosis.
A more than 50% increase in the ACTH level after the CRH test and more than an 80% reduction in the morning cortisol level (8-9 am) after taking 8 mg dexamethasone at 11 pm during a high-dose DST is consistent with a pituitary source, and in the presence of a pituitary adenoma, almost establishes the definitive diagnosis of CS. Experienced neurosurgeons usually achieve 70% to 80% long-term remission rates following surgery. Adrenal carcinoma is typically an aggressive tumor with a poor prognosis; surgical resection at an early stage, along with lifelong mitotane therapy started soon after surgery, offers the only chance for cure or long-term remission. When the tumor is not resectable, bilateral adrenalectomy is performed to correct hypercortisolemia. The consensus emphasized that if the diagnosis of Cushing’s is suspected clinically but initial screening tests are normal, the patient should be re-evaluated at a later date and invasive procedures postponed. In our experiences and in spite of being labor intensive, the combined LDDST-CRH test is of significant value in differentiating CS from pseudo-Cushing’s syndrome. FH type I, or glucocorticoid-remediable hyperaldosteronism (GRH), is an autosomal dominant disease characterized by a chimeric gene between the 11β-hydroxylase and aldosterone synthase, with varying degrees of hyperaldosteronism, which responds to exogenous glucocorticoids. Patients may have headaches, polyuria, nocturia, polydipsia, parasthesias, weakness, and muscle cramps. Although most patients with hyperaldosteronism are not hypokalemic, a low serum potassium level may be noted, either spontaneously or after thiazide or loop diuretic use. The test can be done while the patient is on antihypertensive medications (except spironolactone and eplerenone), without requiring postural stimulation.
Because of differences in therapy, distinguishing an aldosterone-producing adenoma APA and idiopathic hyperaldosteronism is important (Table 2). Adrenal venous sampling is performed during continuous ACTH infusion and relies on demonstration of a gradient for plasma aldosterone in unilateral disease. Unilateral adrenalectomy, usually by a laparoscopic approach, results in normalization of hypokalemia and improvement in hypertension in all patients. Although some experts have advocated screening all hypertensive patients for hyperaldosteronism, we recommend screening only high-risk patients. Adrenal venous sampling is selectively used in some centers, whereas some other centers perform the test in almost all patients.7 In our opinion, if there is a clear adenoma on CT scan on one of the adrenals and the results of the posture test also suggest APA, the patient can be assumed to have the disease and should be referred for surgery. Although their true prevalence is unknown, they occur in about 0.3% of hypertensive patients.
Extra-adrenal pheochromocytomas (paragangliomas) occur in about 15% of cases in the superior and inferior para-aortic areas, including the Zuckerkandl organ (75%), bladder (10%), thorax (10%), and head, neck, and pelvis (5%). Familial predisposition to pheochromocytoma is seen in patients with multiple endocrine neoplasia (MEN) types IIA and IIB, von Hippel-Lindau disease, neurofibromatosis type 1, and familial paragangliomas. Norepinephrine-secreting tumors are associated with sustained hypertension and norepinephrine and epinephrine-secreting tumors are associated with labile hypertension. Attacks are usually precipitated by emotional stress, exercise, anesthesia, abdominal pressure, or ingestion of tyramine- containing foods. Plasma-free metanephrines (total free normetanephrine and metanephrine) have 99% and 97% sensitivity, respectively, for sporadic and familial PHEOs, but there is approximately a 10% to 15% false-positive rate for sporadic PHEO. Medications should be stopped for 3 to 5 days, except labetalol, which needs to be discontinued for 2 weeks (causes analytic interference with some assays). PHEOs are usually larger than 3 cm in diameter and tend to be cystic, with areas of necrosis with increased size.
The low lipid content of PHEO tumors results in a signal intensity decrease from the in-phase to opposed-phase T1-weighted image. Patients should have electrocardiography and cardiac echocardiography before surgery, with further cardiac evaluation if any abnormality is detected. Most experts’ opinions are based on personal experience in centers with large referral bases.
However, there is approximately a 10% to 15% false-positive rate for sporadic pheochromocytoma.
The primary adrenal androgens, dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS sulfate), are under ACTH control and have little intrinsic androgenic activity. In female neonates, androgen excess causes female pseudohermaphroditism (ambiguous genitalia).
In addition, boys exhibit penile enlargement, hair growth in androgen-dependent areas, deepening of the voice, and other secondary sexual characteristics (isosexual precocious puberty).
In girls, it manifests as primary or secondary amenorrhea, different degree of virilization, and increased skeletal maturation, resulting in short adult height. A decrease in size of the testicles, testosterone secretion, and spermatogenesis caused by inhibition of gonadotropin secretion may occur.
Exogenous androgen intake for body building or to increase erythropoiesis may cause acne, hirsutism, and oligomenorrhea or amenorrhea in women and small testes, gynecomastia, and impaired spermatogenesis in men. The associated increased ACTH secretion stimulates adrenal steroid production upstream of the defective enzyme, resulting in increased androgen secretion.

Megestrol acetate, an appetite stimulator used in some patients with advanced cancer or cachexia related to AIDS may be associated with secondary AI.
Skin hyperpigmentation, initially on the extensor surfaces, palmar creases, and buccal mucosa, results from increased levels of ACTH and other pro-opiomelanocortin–related peptides, including melanocyte- stimulating hormone. The ITT is contraindicated in older patients (>65 years) and those with acute illness, seizure disorders, or cardiovascular-cerebrovascular disease.
Enlarged adrenal glands or calcifications suggest an infectious, hemorrhagic, or metastatic cause.
Most patients can be educated to self administer hydrocortisone, 100 mg IM, and reduce the risk of an emergency room visit. Abdominal tenderness and fever are common findings, and adrenal crisis may manifest as an acute abdomen.
Hydrocortisone should be continued, 50 mg every 8 hours, while awaiting laboratory results. Hypotension in patients with adrenal insufficiency may mimic hypovolemic or septic shock and should be considered in the differential diagnosis. During severe illness caused by a marked decrease in the CBG level, albumin has a more significant influence on the total concentration of cortisol. After hemodynamic improvement, a gradual taper of hydrocortisone, depending on the patient’s condition, should be instituted.
The endogenous causes are divided into ACTH-dependent and ACTH-independent CS, as shown in Box 1. Weight gain is almost always present, except in ectopic ACTH secretion (EAS) caused by malignancy.
Agitated depression and lethargy are among the most common psychiatric abnormalities seen in CS patients, but paranoia and overt psychosis may occur. Female patients with adrenal carcinomas often present with signs and symptoms of virilization (hirsutism and acne), breast atrophy, deepening of the voice, temporal hair recession, and clitoromegaly caused by hypersecretion of androgens, along with the cortisol.
Currently, a 24-hour UFC test (with simultaneous urinary creatinine level measurement) is the most widely used initial screening test but a midnight salivary cortisol determination is becoming a good alternative.
Measurement of the 24-hour UFC during the second day of the low-dose DST is of lesser value, and usually does not add any further to the diagnostic accuracy of the baseline 24-hour UFC test. It is always important to remember the effect of increased levels of CBG on serum cortisol levels during pregnancy or in women taking estrogens. Discrepant or inconclusive test results require re-evaluation of the entire clinical picture and a biochemical workup, because CS is almost always a progressive disease. If the CRH stimulation test and DST results are not concordant and MRI does not show a pituitary adenoma, then inferior petrosal sinus sampling to distinguish ectopic from Cushing’s disease is indicated.
An undetectable cortisol level postoperatively, when the patient is off glucocorticoids, is considered to be an excellent indication of long-term cure. Medical therapy with ketoconazole, metyrapone, aminoglutethimide, or mitotane may be considered for patients with a limited life expectancy or for alleviation of hypercortisolemic symptoms before surgery.
A 24-hour UFC assay, overnight 1-mg DST, and midnight salivary cortisol determination were described as first-line screening tests for CS. The workshop recommended the use of bilateral inferior petrosal sinus sampling (BIPSS) in patients whose clinical, biochemical, or radiologic study results are discordant or equivocal. Some investigators have proposed a prevalence as high as 10% in hypertensive patients.5 Women in their fourth to sixth decade of life are affected more often than men. FH type II is an autosomal dominant disorder of both the aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA). Both spironolactone and eplerenone should be discontinued for 6 weeks before biochemical testing and after the potassium level reaches the normal range.
Diuretics, ACE inhibitors, and ARBs should be discontinued for 2 weeks before the tests and potassium needs to be replaced to the normal range. The test may entail risk in older patients, those with uncontrolled hypertension, or those with decompensated heart disease. Side effects include painful gynecomastia, nausea, headaches, impotence, and irregular menstruation. If untreated, the disease can have severe consequences, such as myocardial infarction, heart failure, cerebrovascular accident, and death.
Paragangliomas tend to occur in younger patients <20 years) and are uncommon in those older than 60 years. Genetic screening in patients with apparently sporadic pheochromocytoma is recommended for the following categories of patients: age younger than 20 years, bilateral disease, multiple paragangliomas, or family history of pheochromocytoma or paraganglioma. Large cystic PHEOs may not be associated with hypertension because most of the catecholamines are metabolized within the tumor before being released into circulation. Normalization of the plasma metanephrine level or a decrease in the plasma catecholamine levels by at least 50%, into the normal range for the assay, is considered a normal response. Patients should abstain from caffeinated beverages and alcohol for 24 hours and medications listed in Box 3 for 3 to 5 days before biochemical evaluation.
In a patient suspected to have PHEO, CT scanning of the abdomen and pelvis should be performed first, followed by CT of the chest and neck if no tumor is found (Fig. PHEO tumors typically exhibit signal isointensity with the liver, kidneys, and muscle on T1-weighted images and a characteristically bright, high signal intensity on T2-weighted images (Fig. The specificity of iobenguane sulfate131I is very high, 95% to 100%, and the sensitivity is about 85%. It is preferable that patients be admitted to the hospital 1 day before surgery for close observation. In patients with aggressive tumors, combination chemotherapy (cyclophosphamide, vincristine, dacarbazine) or iobenguane sulfate131I-tagged radiotherapy may be considered, but results have not been promising. Although there are still disagreements about the best initial screening test for PHEO, serum metanephrine or 24-hour urinary metanephrine level determination appears to be the most favored initial test of choice.
However, they are converted to androstenedione and then to testosterone (and estrogen) in both the adrenal gland and peripheral tissues. In women, hirsutism, acne, menstrual irregularities, male pattern baldness, infertility, decreased breast tissue, increased muscle mass, android body habitus, and clitoromegaly may occur, depending on the degree of hyperandrogenism.
Hyperprolactinemia may cause an increase in serum DHEAS and androstenedione levels by direct stimulation of the adrenal gland.
It is a rare disease, with an incidence of 1 per 600,000 to 1,600,000 and a prevalence of 4 to 12 per 1,000,000. Bonus – this is a really easy way to make sure I have green vegetables in my breakfast!

But few people know how to prevent stroke or how to recognize signs and symptoms of stroke or what to do when you suspect someone is having a stroke. Secondary adrenal insufficiency manifests more insidiously with lack of skin hyperpigmentation, salt craving, metabolic acidosis, and hyperkalemia, because mineralocorticoid secretion is intact. Most individuals with normal adrenal function achieve much higher cortisol levels at 60 minutes after cosyntropin injection. A low or normal-range ACTH level, with a low cortisol level, confirms the diagnosis of secondary or tertiary adrenal insufficiency. In rare circumstances, CT-guided percutaneous fine-needle aspiration of enlarged adrenal glands may help establish the diagnosis. Serial follow-up of adrenal function in critically patients with clinical features suggestive of AI is recommended. A subset of patients with septic shock may benefit from physiologic stress dose glucocorticoids. An elevated salivary cortisol level in most cases should be confirmed by a 24-hour UFC test before referral to surgery.
Another clinical scenario that may be associated with normal screening tests is cyclic CS, which needs to be ruled out by periodic evaluation. Localizing tumors that produce ectopic ACTH is accomplished by chest and abdominal CT studies, followed by neck CT if no source is found.
The workshop briefly discussed the promising results from the midnight salivary cortisol test, which we believe should be part of the diagnostic workup for most patients suspected to have CS, particularly if early disease is suspected. We usually carry out BIPSS in most of our patients with ACTH- dependent CS who have no clear adenoma on pituitary MRI. A solitary aldosterone-producing adenoma (65%) and bilateral idiopathic hyperplasia (30%) are the most common subtypes of primary aldosteronism.
The degree of hypertension is usually moderate to severe, and may be refractory to conventional antihypertensive agents. Its presence reduces the secretion of aldosterone and thus should be corrected before the laboratory evaluation of hyperaldosteronism.
Measurement of the 24-hour urinary potassium level can be useful in assessing the cause of a low potassium level, including surreptitious vomiting or laxative abuse. Hypertension may be controlled by calcium channel blockers, beta blockers, or α1-adrenergic receptor blockers, which do not significantly affect the biochemical workup for hyperaldosteronism. The blood pressure response to spironolactone before surgery often predicts the blood pressure response to surgery in those with an APA. Serum potassium and magnesium levels should be monitored to avoid hyperkalemia and hypomagnesemia. Other symptoms include orthostatic hypotension, weight loss, dyspnea, polyuria, polydipsia, visual blurring, focal neurologic symptoms, and change in mental status. In general, a plasma-free metanephrine level more than three or four times the upper normal has 100% specificity for PHEO. Nasal decongestants, some antihypertensives, antidepressants, antipsychotics, and cocaine affect iobenguane sulfate131I uptake and have to be withheld for 1 to 3 days before the study. NCAH affects from 1% to 10% of hyperandrogenic women, depending on their ethnic background.
Diabetes can usually be treated and managed very effectively but it is important that people with gestational diabetes cardiovascular risk learning type 1 disability diabetes take Diabetes Cortisol Levels 2 Lisinopril Type responsibility for their condition and follow the advice of their doctors. The effect of intensive diabetes treatment on the development and progression of long-term complications in insulin-dependent diabetes mellitus: the Diabetes Control and Complications Trial. Addison’s disease may coexist with other autoimmune conditions, such as type 1 diabetes, hypothyroidism, or hypoparathyroidism. Secondary and tertiary adrenal insufficiencies only affect cortisol secretion, because ACTH has only a minor role in regulation of aldosterone secretion. Fatigue, hyponatremia, and hypoglycemia are some of the clinical manifestations in secondary adrenal insufficiency. Metyrapone blocks the final step in cortisol biosynthesis, resulting in a reduction in cortisol secretion, which in turn stimulates ACTH secretion.
Patients with tuberculous adrenal insufficiency usually have evidence of active systemic disease. The dose is adjusted based on clinical status, including the presence or absence of orthostatic hypotension, hypertension, and electrolyte imbalance. In patients with equivocal biochemical results, a trial of 2 or 3 days of stress dosage glucocorticoids is appropriate, as long as it will be discontinued in the absence of any significant hemodynamic improvement. Such therapy has not yet been proven to be effective and safe in all patients with septic shock. CS has profound effects on bone, causing poor linear growth in children and osteoporotic vertebral collapse and pathologic fractures in adults. A normal sleeping pattern is necessary for an accurate salivary cortisol level measurement for the evaluation of CS. A flat response of ACTH to CRH during the test suggests an adrenal cause, but a more than 50% increase in the ACTH level during the test is consistent with Cushing’s disease.
An octreotide scan may be of some value in patients with ectopic CS and negative imaging studies. After pituitary tumors are treated, lifelong medical follow-up is necessary to detect early recurrence, monitor hormone replacement, and treat any complications related to the tumor. Potassium supplementation is stopped in most patients without any underlying heart disease at the beginning of the salt-loading test.
The presence of a solitary adrenal tumor with a normal contralateral adrenal gland is usually consistent with an APA. Eplerenone is a steroid-based antimineralocorticoid that blocks the aldosterone receptor selectively and has a better side effect profile.
Bilateral adrenal pheochromocytomas (5%-10% of cases) are usually seen as part of familial syndromes.
Urinary vanillylmandelic acid (VMA) measurement has a high false-negative rate (41%) and should not be used for screening purposes, but a positive result has approximately 86% and 99% specificity for sporadic and hereditary PHEOs, respectively.
Because of the potential for inducing a hypertensive crisis, beta blockers should never be used without simultaneously using alpha blockers. An adrenal tumor with a noncontrast Hounsfield unit (HU) lower than 10 is extremely unlikely to be PHEO. We usually prefer CT scanning over MRI as the initial imaging study with a biochemical workup diagnostic for PHEO because of cost and widespread availability. Beta blockers should be added only after alpha blockade has been instituted to prevent unopposed alpha receptor activation, which may result in hypertensive crisis. Peak levels occur in the third decade of life and decline progressively to 25% of peak levels around the age of 80 years.
Both CAH and NCAH are associated with an increased incidence of adrenal adenomas and testicular adrenal rest tumors.13 This warrants CT scanning of the adrenal glands and testicular ultrasonography (men) in patients with biochemical confirmation.

When the biochemical work up suggests secondary or tertiary adrenal insufficiency, magnetic resonance imaging (MRI) of the pituitary gland is indicated if glucocorticoid therapy as the cause of the secondary adrenal insufficiency has been ruled out. Patients may need to double the dose of fludrocortisone or increase salt intake during the summer, when the weather is hot. Lifelong glucocorticoid replacement therapy should not be sanctioned on the basis of an equivocal biochemical test result in an acutely ill patient. Values of UFC above three or four times upper normal for the assay are usually diagnostic for CS, especially when repeated and confirmed.
Idiopathic adrenal hyperplasia may be accompanied by adrenocortical nodules and is associated with lower aldosterone levels and less severe hypertension, compared with adenomas.
The left ventricular hypertrophy is disproportionate to the level of blood pressure and improves after treatment of hyperaldosteronism, even if hypertension persists.
Low or suppressed PRA during therapy with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) suggests hyperaldosteronism. During day 4 of salt loading, a 24-hour urine sample must be collected by the patient for aldosterone, sodium, potassium, and creatinine level testing. Determination of plasma aldosterone levels before and 2 hours after an upright posture (with ambulation) and a plasma 18-hydroxycorticosterone level can further help distinguish APA from IHA. However, spironolactone is the favored initial treatment, because it is more potent and costs less.
Malignant pheochromocytomas (10% of adrenal cases) have a higher prevalence in ectopic PHEOs and lower prevalence in familial PHEOs. If the plasma-free metanephrine concentration is normal, no other diagnostic test is necessary except in those with small tumors found during workup for familial disease, patients with a history of PHEO or, rarely, patients with a dopamine-producing paraganglioma. Uptake of iodine by the thyroid gland should be blocked with potassium iodide (SSKI; five drops three times a day, starting on the day of iobenguane sulfate131I and 3 days afterward).
Calcium channel blockers (CCBs) can be used for medical preparation or may be added if there is persistent or labile hypertension. The main differential diagnosis for NCAH is polycystic ovary syndrome (PCOS), which is about 40 to 50 times more common (Table 3).12 Distinguishing the two only on clinical grounds is difficult, because both can be associated with varying degrees of hyperandrogenism and ovulatory dysfunction. The consensus statement from the Lawson Wilkins Pediatric Endocrine Society and the European Society for Pediatric Endocrinology about CAH almost exclusively discusses the diagnosis and management of the classic form of the disease. Tumors are usually larger than 6 cm, invade the capsule, metastasize early, and typically recur after surgery.
Patients with secondary or tertiary adrenal insufficiency do not need mineralocorticoid replacement. All patients should wear some form of identification indicating their adrenal insufficiency status.
About 90% of patients with ACTH-dependent CS have a pituitary cause and the rest are ectopic in origin. Alternatively, potassium-sparing diuretics such as amiloride or triamterene may be used, but they lack the mineralocorticoid receptor antagonist benefits. If the iobenguane sulfate131I study is negative, fluorodeoxyglucose positron emission tomography (PET) scanning or oxidronate (Octreoscan) may be used with some success for visualization (see Fig. The nonspecific α1-adrenergic blocker phenoxybenzamine has a greater side effect profile and may result in prolonged hypotension after surgery.
After surgery, blood pressure and blood glucose levels need to be closely monitored, antihypertensive agents withheld, and normal saline infusion continued.
One wonders how long it took the it’s also well-known that glyburide given by mistake to non-diabetic patients will cooking for diabetics uk diabetic weekly food planner result in profound An overdose of insulin can cause hypoglycemia (low blood sugar) with symptoms of weakness trembling unresponsiveness seizures coma and death.
Moon face and supraclavicular and dorsocervical fat pads (buffalo hump) are nonspecific and accompany obesity from other causes. Patients with an inconclusive adrenal CT scan or discordant results are referred for adrenal venous sampling.
The diagnosis of malignant pheochromocytoma relies on the presence of metastases and not on the histology of the tumor. Deciding exactly when to begin insulin therapy is problematic for physicians who treat type 2 diabetes. The lack of a commercially available 1-μg cosyntropin dose may be a potential for error.
Another supportive measure is correction of hypokalemia with the addition of aldactone at the end of biochemical workup. Lifelong follow-up is necessary for all patients, with closer follow-up of those with familial, large, extra-adrenal, or bilateral tumors.
