A progressive decrease in blood volume contributes to hypotension, weakness, and microcardia. Increased excretion of water by the kidneys, because of decreased reabsorption of sodium and chloride, results in progressive dehydration and hemoconcentration. Emesis, diarrhea, and anorexia are common and contribute to the animal’s deterioration. Weight loss is frequently severe. Similar clinical signs are seen in cats with hypoadrenocorticism. Decreased gluconeogenesis and increased sensitivity to insulin contribute to the development of moderate hypoglycemia. In some dogs, hyperpigmentation of the skin is seen because of the lack of negative feedback on the pituitary gland and increased ACTH release. Atypical Addison disease has been reported in dogs and is associated with hypocortisolemia with normal electrolytes. Clinical signs are similar to those seen in dogs with both glucocorticoid and mineralocorticoid insufficiency. The adrenal cortex is reduced to one-tenth or less of its normal thickness and consists primarily of the adrenal capsule. The adrenal medulla is relatively more prominent and, with the capsule, makes up the bulk of the remaining adrenal glands. After obtaining a baseline blood sample, ACTH (gel or synthetic) is administered. Gel preparations are administered IM, and a second blood sample is obtained 2 hours later. Synthetic preparations are administered IM or IV with a second blood sample 1 hour later.Urine output should be assessed to determine whether the dog is becoming anuric. Fluids should be continued, at a rate appropriate to match ongoing losses, until the clinical signs and laboratory abnormalities have resolved. Electrolytes, renal function, and glucose should be monitored regularly to assess response to therapy. Serum electrolytes should be monitored weekly until the proper dose is determined. Some dogs (especially dogs on DOCP) also require daily oral glucocorticoid therapy to adequately control clinical signs.

Isolated aldosterone insufficiency appears to be very rare, whereas isolated glucocorticoid insufficiency is likely underdiagnosed given the lack of electrolyte abnormalities. The clinical signs of hypoadrenocorticism are often vague, may wax and wane over time, are rarely pathognomonic, and may be present for days, weeks, or months before diagnosis. Diagnosis depends on an accurate history, physical examination, and screening laboratory tests (CBC, chemistry panel, urinalysis). Confirmation requires adrenal function testing using the ACTH stimulation test. Treatment is highly successful but often lifelong. The disease may be familial in Standard Poodles, West Highland White Terriers, Great Danes, Bearded Collies, Portuguese Water Dogs, and a variety of other breeds. The cause of primary adrenocortical failure usually is unknown, although most cases probably result from an autoimmune process. Other causes include destruction of the adrenal gland by granulomatous disease, metastatic tumor, hemorrhage, infarction, adrenolytic agents ( mitotane ), or adrenal enzyme inhibitors (trilostane). Isolated glucocorticoid insufficiency is more commonly seen in older dogs with vague GI signs, weight loss, normal electrolyte concentrations, hypoalbuminemia and hypocholesterolemia. Although hypoadrenocorticism is seen in dogs of any breed, sex, or age, idiopathic adrenocortical insufficiency is most common in young, female adult dogs. This may be related to its suspected immune-mediated pathogenesis. Potassium excretion by the kidneys is reduced and results in a progressive increase in serum potassium levels. Hyponatremia and hypochloremia result from renal tubular loss. Severe hyperkalemia may result in bradycardia and an irregular heart rate with changes in the ECG. Some dogs develop a pronounced bradycardia (heart rate ?50 bpm) that predisposes to weakness or circulatory collapse after minimal exertion.

In children, the most common cause of primary adrenal insufficiency is congenital adrenal hyperplasia, but other genetic disorders are being increasingly recognized as causes. A low serum concentration of sodium ( hyponatremia ) and a high concentration of potassium ( hyperkalemia ) result. However, when adrenal insufficiency is caused by inadequate adrenocorticotropic hormone (ACTH) production ( secondary adrenal insufficiency ), electrolyte levels are often normal or only mildly deranged, and the circulatory problems are less severe. In the absence of cortisol, insufficient carbohydrate is formed from protein; hypoglycemia and decreased liver glycogen result. Weakness follows, due in part to deficient neuromuscular function. Resistance to infection, trauma, and other stress is decreased. Myocardial weakness and dehydration reduce cardiac output, and circulatory failure can occur. Thus, adrenal insufficiency secondary to pituitary failure does not cause hyperpigmentation. Black freckles are common on the forehead, face, neck, and shoulders. Bluish black discolorations of the areolae and mucous membranes of the lips, mouth, rectum, and vagina occur. Decreased tolerance to cold, with hypometabolism, may be noted. Dizziness and syncope may occur. Weight loss, dehydration, and hypotension are characteristic of the later stages of Addison disease. Shock and fever may be the only signs. Peutz-Jeghers syndrome is characterized by pigmentation of the buccal and rectal mucosa. Frequently, hyperpigmentation occurs with vitiligo, which may indicate Addison disease, although other diseases can cause this association. Most myopathies that cause weakness can be differentiated by their distribution, lack of abnormal pigmentation, and characteristic laboratory findings. In contrast, patients with hypoglycemia due to oversecretion of insulin can have attacks at any time, usually have increased appetite with weight gain, and have normal adrenal function.

Dogs with atypical Addison disease require only replacement doses of prednisone, although it is recommended that electrolytes be monitored every 3 mo for the first year after diagnosis.Supportive therapy and rest are indicated in cases of chronic Addison disease. Therefore, the clinician must always consider the diagnosis in patients with the appropriate signalment and clinical signs. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. The Veterinary Manual was first published in 1955 as a service to the community. The legacy of this great resource continues in the online and mobile app versions today. In the top right panel, hyperpigmentation of the palmar creases is visible in a patient with Addison disease. In the bottom left panel hyperpigmented macules of the gums are visible in this patient with Addison disease.It causes various symptoms, including hypotension and hyperpigmentation, and can lead to adrenal crisis with cardiovascular collapse. Diagnosis is clinical and by finding elevated plasma adrenocorticotropic hormone (ACTH) with low plasma cortisol. Treatment depends on the cause but generally includes hydrocortisone and sometimes other hormones. Other causes include trauma, surgery, and sodium loss due to excessive sweating. Even with treatment, Addison disease may cause a slight increase in mortality. It is not clear whether this increase is due to mistreated adrenal crises or long-term complications of inadvertent over-replacement. The remainder result from destruction of the adrenal gland by granuloma (eg, tuberculosis, histoplasmosis ), tumor, amyloidosis, hemorrhage, or inflammatory necrosis. Hypoadrenocorticism can also result from administration of drugs that block corticosteroid synthesis (eg, ketoconazole, the anesthetic etomidate ).

The simple short test is usually done initially, because a normal response obviates the need for further investigation. If ACTH stimulation testing is done, elevated ACTH levels together with low cortisol levels confirm the diagnosis. Adrenal autoantibodies can be assessed. In patients with autoimmune disease, the adrenals are atrophied, whereas in patients with tuberculosis or other granulomas, the adrenals are enlarged (initially) with frequent calcification. Bilateral adrenal hyperplasia, particularly in children and young adults, suggests a genetic enzyme defect. Thus, hydrocortisone (identical to cortisol) is given in 2 or 3 divided doses with a typical total daily dose of 15 to 30 mg. One regimen gives half the total in the morning, and the remaining half split between lunchtime and early evening (eg, 10 mg, 5 mg, 5 mg). Others give two thirds in the morning and one third in the evening. Doses immediately before bed should generally be avoided because they may cause insomnia. Alternatively, prednisone 5 mg orally in the morning and possibly an additional 2.5 mg orally in the evening may be used. Additionally, fludrocortisone 0.1 to 0.2 mg orally once a day is recommended to replace aldosterone. The easiest way to adjust the fludrocortisone dosage is to ensure that the renin level is within the normal range and that blood pressure and serum potassium level are normal. In some patients, fludrocortisone causes hypertension, which is treated by reducing the dosage or starting a nondiuretic antihypertensive. Some clinicians tend to give too little fludrocortisone in an effort to avoid use of antihypertensives. If nausea and vomiting preclude oral therapy, parenteral therapy is necessary. Patients should be instructed when to take supplemental prednisone or hydrocortisone and taught to self-administer parenteral hydrocortisone for urgent situations. A preloaded syringe with 100 mg hydrocortisone should be available to the patient.

Unlike those with Addison disease, these patients are not likely to have hyperpigmentation, hyperkalemia, and increased BUN. It is important to note that ACTH levels within the normal range are inappropriate when cortisol levels are very low. If time is too short (eg, emergency surgery), the patient is given hydrocortisone empirically (eg, 100 mg IV or IM), and provocative testing is done subsequently. Secondary adrenal insufficiency is diagnosed by a prolonged ACTH stimulation test, glucagon stimulation test, or insulin tolerance test. In the glucagon stimulation tests, plasma ACTH and cortisol levels fail to rise in response to glucagon in patients with secondary adrenal insufficiency. The insulin tolerance test is not recommended in patients suspected of having severe adrenal insufficiency. Some authorities believe that in patients with suspected secondary adrenal insufficiency, a low-dose ACTH stimulation test using 1 mcg IV instead of the standard 250 mcg-dose should be done because such patients may react normally to the higher dose. Patients taking glucocorticoid supplements or spironolactone should not take them on the day of the test. However, because pituitary failure may cause adrenal atrophy (and hence failure to respond to ACTH), the patient may need to be primed with long-acting ACTH 1 mg IM once a day for 3 days before the ACTH stimulation test if pituitary disease is suspected. Cosyntropin 1 mg IM is given, and cortisol is measured at intervals for 24 hours, typically at 1, 6, 12, and 24 hours. Results for the first hour are similar for both the short (sampling stopped after 1 hour) and prolonged tests, but in Addison disease there is no further rise beyond 60 minutes. In secondary and tertiary adrenal insufficiency, cortisol levels continue to rise for ? 24 hours. Only in cases of prolonged adrenal atrophy is adrenal priming (with long-acting ACTH) necessary.

Also, when stress occurs, the body is not able to stimulate production of the additional corticosteroids that are needed. Instead, doctors gradually reduce (taper) the dose over weeks and sometimes months. Corticosteroid use may need to be resumed in people who become ill or otherwise severely stressed within weeks of having the corticosteroid tapered and stopped. In this disorder, the adrenal glands are underactive because the corticotropin from the pituitary gland is not stimulating them, not because the adrenal glands have been destroyed or have otherwise directly failed. Lack of corticotropin affects adrenal secretion of cortisol much more than secretion of aldosterone. Secondary adrenal insufficiency is diagnosed by blood tests. Unlike in Addison disease, sodium and potassium levels tend to be near normal in secondary adrenal insufficiency, and the corticotropin level is low. Secondary adrenal insufficiency is treated with synthetic corticosteroids such as hydrocortisone or prednisone. These problems may develop gradually and insidiously. People with Addison disease develop patches of dark skin. The darkness may seem like tanning, but it appears on areas not even exposed to the sun. Even people with dark skin can develop excessive pigmentation, although the change may be harder to recognize. Black freckles may develop over the forehead, face, and shoulders, and a bluish black discoloration may develop around the nipples, lips, mouth, rectum, scrotum, or vagina. Many become unable to tolerate cold. Unless the disease is severe, symptoms tend to become apparent only during times of stress. Periods of hypoglycemia, with nervousness and extreme hunger for salty foods, can occur, particularly in children. Severe abdominal pain, profound weakness, extremely low blood pressure, kidney failure, and shock may occur. An adrenal crisis often occurs if the body is subjected to stress, such as an accident, injury, surgery, or severe infection.

If adrenal crisis is not treated, death may quickly follow. Sometimes a major stress makes the symptoms more obvious and precipitates a crisis. Doctors who suspect Addison disease measure cortisol levels, which may be low, and corticotropin levels, which may be high. However, doctors may need to confirm the diagnosis by measuring cortisol levels before and after an injection of a synthetic form of corticotropin. If cortisol levels are low, further tests are needed to determine if the problem is Addison disease or secondary adrenal insufficiency. Usually, treatment can be started with hydrocortisone (the drug form of cortisol ) or prednisone (a synthetic corticosteroid) taken by mouth. However, people who are severely ill may be given hydrocortisone intravenously or intramuscularly at first and then hydrocortisone tablets. Because the body normally produces most cortisol in the morning, replacement hydrocortisone should also be taken in divided doses, with the largest dose in the morning. Hydrocortisone will need to be taken every day for the rest of the person’s life. Larger doses of hydrocortisone are needed when the body is stressed, especially as a result of an illness, and may need to be given by injection if the person has severe diarrhea or vomiting. Supplemental testosterone is not usually needed, although there is some evidence that replacement with DHEA improves the quality of life in some people. Although treatment must be continued for life, the outlook is excellent. They should also carry an injection of hydrocortisone for use in an emergency.

A bracelet or wallet card giving the diagnosis and corticosteroid dose may help in case of adrenal crisis that renders the patient unable to communicate. Immediate intravascular volume expansion is done by giving 1 L of a 5% dextrose in 0.9% saline solution over 1 to 2 hours. Additional 0.9% saline is given IV until hypotension, dehydration, and hyponatremia have been corrected. Serum potassium may fall during rehydration, requiring replacement. Mineralocorticoids are not required when high-dose hydrocortisone is given. When illness is less acute, hydrocortisone 50 or 100 mg IM every 6 hours can be given. Restoration of blood pressure and general improvement should occur within 1 hour after the initial dose of hydrocortisone. Inotropic agents may be needed until the effects of hydrocortisone are achieved. Maintenance oral doses of hydrocortisone (15 to 30 mg) and fludrocortisone (0.1 mg) are given daily thereafter, as described above. Recovery depends on treatment of the underlying cause (eg, infection, trauma, metabolic stress) and adequate hydrocortisone therapy. Complications of corticosteroid therapy may include psychotic reactions. If psychotic reactions occur, then the hydrocortisone dose can be reduced to the lowest level consistent with maintaining blood pressure and good cardiovascular function. Antipsychotics may be temporarily required, but use should not be prolonged.

Carcinoid syndrome is a group of symptoms that develop as a result of overproduction of these hormones.

In which part of the body do carcinoid tumors typically originate? In 70% of people with Addison disease, the cause is not precisely known, but the adrenal glands are affected by an autoimmune reaction in which the body’s immune system attacks and destroys the adrenal cortex (the outer part of the gland, which is distinct from the adrenal medulla, the inner part which produces different hormones). In the other 30%, the adrenal glands are destroyed by cancer, an infection such as tuberculosis, or another identifiable disease. In infants and children, Addison disease may be due to a genetic abnormality of the adrenal glands. In addition, loss of androgens may cause a loss of body hair in women. In men, testosterone from the testes more than makes up for this loss. DHEA may have additional effects that do not relate to androgens. However, this loss does not cause symptoms. The kidneys are not able to retain sodium easily, so when a person with Addison disease loses too much sodium, the level of sodium in the blood falls, and the person becomes dehydrated. Severe dehydration and a low sodium level reduce blood volume and can lead to shock. The deficiency prevents the body from manufacturing carbohydrates, which are needed for cellular function, and protein, for fighting infections properly and controlling inflammation. Muscles weaken, and even the heart can become weak and unable to pump blood adequately. In addition, the blood pressure may become dangerously low. They therefore are susceptible to serious symptoms and complications when confronted with illness, extreme fatigue, severe injury, surgery, or, possibly, severe psychologic stress. Corticotropin also stimulates melanin production, so the skin and the lining of the mouth often develop a dark pigmentation. This suppression occurs because large doses of corticosteroids signal the hypothalamus and pituitary gland to stop producing the hormones that normally stimulate adrenal function.

Lynn 5.0 out of 5 stars Wish I’d had this book last year when I got ill, now realise I was also heading into a Addisons crisis.

Explains how to identify symptoms of a crisis and how to manage yourself when you do get ill ( as most GPs have little understanding of the disease as it’s not very common). Well written and lots of information I didnt know e.g. don’t eat licquorice ??, and it’s common to experience salt cravings. Will be passing it to my sister to read as she’s my main supporter.It’s a nice compact book with the essentials all these. Some of the information I already knew but always good to review your own knowledge anyway. As Addison’s is such a complex illness- it’s not simply just absence of Cortisol. This but ok helps others understand what is effected and why. By understanding it- helps us enormously. But there is also lots of new information, that you may not be aware of or have heard before. For me, one of these was included in the section discussing the reasons for an Addison’s Crisis (or leading to). The percentages are interesting to read, as they certainly do take into account the impact of emotional stress on some one with Addison’s Disease.It explains day to day living very clearly and also how to recognise a crisis. I bought the kindle version and found the links very helpful also. I have decided to buy the paper version for some relatives that my daughter stays with on a regular basis so that they too will understand the illness fully.My 7 year old was recently diagnosed with the disease and this book has really helped answer many of the questions I had. It is a must read if you or anyone you know has Addison's.It did not help me at all with this. Months later after trial and error I was able to get control of my Addisons by circadian rhythm dosing hydrocortisone, which many other Addisonians I know use too. This is not even mentioned in the book.

Whilst is is impossible to mention all the drugs that interact with hydrocortisone, I think antifungal drugs should have been mentioned as it can effectively double the hydrocortisone exposure, leading to a de-stablishing effect upon withdrawal.If you have just been diagnosed with this DISEASE this booklet is a must! This content does not have an Arabic version. Make an appointment. Explore now. Choose a degree. Get updates. A blood test can also measure antibodies associated with autoimmune Addison's disease. ACTH signals your adrenal glands to produce cortisol. This test measures the level of cortisol in your blood before and after an injection of synthetic ACTH. You may be given this test if doctors think you may have adrenal insufficiency as a result of pituitary disease (secondary adrenal insufficiency). The test involves checking your blood sugar (blood glucose) and cortisol levels after an injection of insulin. In healthy people, glucose levels fall and cortisol levels increase. You may also undergo an MRI scan of your pituitary gland if testing indicates you might have secondary adrenal insufficiency. You will be given hormone replacement therapy to correct the levels of steroid hormones your body isn't producing. Some options for treatment include oral corticosteroids such as: These hormones are given on a schedule to mimic the normal 24-hour fluctuation of cortisol levels. If you're ill with vomiting and can't keep down oral medications, you may need injections of corticosteroids. A steroid emergency card and medical alert identification will let emergency medical personnel know what kind of care you need. Also have a written action plan. Missing even one day of medication may be dangerous, so keep a small supply of medication at work and with you whenever you travel. The kit contains a needle, syringe and injectable form of corticosteroids to use in case of emergency.

Keep an ongoing relationship with your doctor to make sure that the doses of replacement hormones are adequate, but not excessive. If you're having ongoing problems with your medications, you may need adjustments in the doses or timing of the medications. See your doctor or an endocrinology specialist at least once a year. Your doctor may recommend annual screening for a number of autoimmune diseases. They are also working on pumps implanted under the skin that can deliver steroids in more-accurate doses. However, when you call to set up an appointment, you may be referred to an endocrinologist. Here's some information to help you get ready for your appointment, and what to expect from your doctor. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet. Sometimes it can be difficult to recall all the information provided to you during an appointment. Someone who accompanies you may remember something that you missed or forgot. List your questions from most important to least important in case time runs out. For Addison's disease, some basic questions to ask your doctor include: How can I best manage them together? What websites do you recommend? Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask: Accessed Oct. 14, 2018.
