Acute adrenal crisis

Adrenal crisis; Addisonian crisis; Acute adrenal insufficiency

Acute adrenal crisis is a life-threatening condition that occurs when there is not enough cortisol. This is a hormone produced by the adrenal glands.

Causes

The adrenal glands are small hormone-releasing organs located on top of each kidney. They are made up of an outer portion called the cortex, and an inner portion called the medulla.

The cortex produces 3 hormones:

  • Glucocorticoid hormones (such as cortisol) maintain sugar (glucose) control, blood pressure, decrease (suppress) immune response, and help the body respond to stress.
  • Mineralocorticoid hormones (such as aldosterone) regulate sodium, water and potassium balance.
  • Sex hormones, androgens (male) and estrogens (female), affect sexual development and sex drive.

The medulla produces the hormone adrenaline (also called epinephrine). Both cortisol and adrenaline are released in response to stress.

Cortisol production is regulated by the pituitary. This is a small gland just underneath the brain. The pituitary releases adrenocorticotropic hormone (ACTH). This is a hormone that causes the adrenal glands to release cortisol.

Adrenaline production is regulated by nerves coming from the brain and spinal cord and by circulating hormones.

Adrenal crisis can occur from any of the following:

  • The adrenal gland is damaged due to, for example, Addison disease or other adrenal gland disease, or surgery
  • The pituitary is injured and cannot release ACTH (hypopituitarism)
  • Adrenal insufficiency is not properly treated
  • You've been taking glucocorticoid medicines for a long time, and suddenly stop
  • You've become very dehydrated
  • Infection or other physical stress

Symptoms

Symptoms and signs of adrenal crisis can include any of the following:

Exams and Tests

Tests that may be ordered to help diagnose acute adrenal crisis include:

Treatment

Adrenal crisis is a medical emergency. In adrenal crisis, you need to be given the medicine hydrocortisone right away through a vein (intravenous) or muscle (intramuscular). You may receive intravenous fluids if you have low blood pressure.

You will need to go to the hospital for treatment and monitoring. If infection or another medical problem caused the crisis, you may need additional treatment.

Many people with primary or secondary adrenal insufficiency have an emergency syringe with hydrocortisone at home that a family member can inject into muscle if they are too sick or too weak to take their hydrocortisone pills.

Outlook (Prognosis)

Shock may occur if treatment is not provided early, and it can be life threatening from very low blood pressure and heart problems.

When to Contact a Medical Professional

Go to the emergency room or call the local emergency number (such as 911) if you develop symptoms of acute adrenal crisis.

Contact your health care provider if you have Addison disease or hypopituitarism and are unable to take your glucocorticoid medicine for any reason.

If you have Addison disease, you will usually be told to temporarily increase the dosage of your glucocorticoid medicine if you are stressed or ill, or before having surgery. This is called 'stress' or 'sick-day' dosing.

Prevention

If you have Addison disease, learn to recognize the signs of potential stress that may cause an acute adrenal crisis. If you have been instructed by your provider, be prepared to give yourself an emergency shot of glucocorticoid or to increase your dosage of oral glucocorticoid medicine in times of stress. Parents should learn to do this for their children who have adrenal insufficiency.

Always carry medical ID (card, bracelet, or necklace) that says you have adrenal insufficiency. The ID should also say the type of medicine and dosage you need in case of an emergency.

If you take glucocorticoid medicines for pituitary ACTH deficiency, be sure you know when to take a stress dose of your medicine. Discuss this with your provider.

Never miss taking your medicines.

  • Endocrine glands

    Endocrine glands - illustration

    Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

    The adrenal gland secretes steroid hormones such as cortisol and aldosterone. It also makes precursors that can be converted to sex steroids (androgen, estrogen). A different part of the adrenal gland makes adrenaline (epinephrine). When the glands produce more or less hormones than required by the body, disease conditions may occur.
