Adrenal Cortical Hypofunction (ACH): A Condition of Hormonal Imbalance

Adrenal cortical hypofunction, also known as adrenal insufficiency or Addison's disease, is a condition where the adrenal glands do not produce enough hormones, specifically cortisol and aldosterone. This hormonal imbalance can affect various bodily functions, leading to a range of symptoms.

Causes and Risk Factors ACH can be caused by various factors, including:

• A history of having a disease or surgery that affects the pituitary gland or the adrenal glands [1]
• Certain genetic changes that affect the pituitary or adrenal glands [1]
• Autoimmune endocrine conditions, such as hypothyroidism or type 1 diabetes [1]

Symptoms The symptoms of ACH can vary from person to person but often include:

• Fatigue and weakness [2][3]
• Nausea and vomiting [4]
• Weight loss [5]
• Low blood pressure [6]
• Cardiac arrhythmias [7]
• Salt hunger [8]
• Potency disorders [9]

Types of ACH There are two main types of adrenal cortical hypofunction:

1. Primary adrenal insufficiency: This occurs when the adrenal glands are damaged and cannot produce enough cortisol and aldosterone [10].
2. Secondary adrenal insufficiency: This is caused by a lack of stimulation from the pituitary gland, leading to insufficient production of cortisol and aldosterone [11].

Treatment and Management With proper treatment, most people with ACH can lead normal, active lives. Treatment typically involves replacing the deficient hormones through medication and lifestyle changes.

Adrenal Cortical Hypofunction: Signs and Symptoms

Adrenal cortical hypofunction, also known as adrenal insufficiency, is a condition where the adrenal glands do not produce enough hormones, such as cortisol and aldosterone. This can lead to various signs and symptoms, which can be mild or severe.

Common Symptoms:

• Fatigue and muscle weakness [3]
• Loss of appetite and weight loss [4]
• Abdominal pain and nausea [5]
• Dehydration and confusion [6]
• Low blood pressure and fainting [7]
• Dark skin patches (in primary adrenal insufficiency) [7]

Other Possible Symptoms:

• Dizziness or lightheadedness when standing up after sitting or lying down [7]
• Confusion, loss of consciousness, or coma in severe cases [8]
• Severe nausea and vomiting [6]
• Diarrhea [6]
• Abdominal pain or flank pain [8]

Gradual Onset:

The symptoms of adrenal insufficiency often come on gradually and progressively worsen over months. This can make it difficult to diagnose, as early symptoms may be mistaken for other conditions.

Types of Adrenal Insufficiency:

There are two main types of adrenal insufficiency:

• Primary adrenal insufficiency (Addison's disease): caused by autoimmune disease or sudden stopping of cortisol production
• Secondary adrenal insufficiency: caused by the pituitary gland not producing enough ACTH, leading to decreased cortisol production

Diagnosing Adrenal Cortical Hypofunction

Adrenal cortical hypofunction, also known as adrenal insufficiency, can be challenging to diagnose due to its nonspecific symptoms and the fact that cortisol levels can fluctuate throughout the day. However, several diagnostic tests can help confirm the condition.

• ACTH Stimulation Test: This is considered the best test for diagnosing or excluding adrenal insufficiency when baseline cortisol values are indeterminate [1]. The test measures blood levels of sodium, potassium, cortisol, and adrenocorticotropic hormone (ACTH) before and after administering a synthetic form of ACTH.
• Cosyntropin Stimulation Test: This test is another option for confirming adrenal insufficiency. It involves measuring cortisol levels in response to cosyntropin, a synthetic form of ACTH [6].
• Insulin Tolerance Test: This test is considered the gold standard for diagnosing adrenal insufficiency but is typically reserved for cases where other tests are inconclusive due to its invasiveness and potential risks [6].

Other Diagnostic Tests

In addition to these specific tests, healthcare providers may also use a combination of clinical evaluation, medical history, and laboratory tests to diagnose adrenal cortical hypofunction. These may include:

• Blood tests to measure cortisol levels
• Electrolyte panel to assess sodium and potassium levels
• ACTH level measurement

Confirmatory Testing

Confirmatory testing can be done using the cosyntropin (Synacthen) stimulation test or the insulin tolerance test, which is the gold standard for diagnosing adrenal insufficiency [6].

Treatment Overview

Adrenal cortical hypofunction, also known as primary adrenal insufficiency (Addison disease), requires daily treatment with glucocorticoid and mineralocorticoid pills to manage the condition effectively [12][13]. The goal of treatment is to replace the deficient hormones and prevent complications such as adrenal crisis.

Glucocorticoids

Glucocorticoids, such as cortisone systemic, are essential for treating adrenal cortical hypofunction [4][9]. These medications help maintain normal cortisol levels in the body. Treatment usually requires lifelong hormone replacement, and correct use of these hormone medications is crucial to minimize symptoms and the chance of adrenal crisis [9][12].

Mineralocorticoids

Mineralocorticoids, such as hydrocortisone, are also necessary for treating adrenal cortical hypofunction [8]. These medications help maintain bodily sodium, fluid balance, and blood pressure. Inadequate mineralocorticoid replacement can lead to complications such as dehydration and electrolyte imbalances.

Treatment Regimens

Treatment regimens may vary depending on individual needs. For example, hydrocortisone 15-20 mg PO every morning and 5-10 mg PO between 4:00-6:00 PM every afternoon may be prescribed to maintain cortisol levels [8]. It is essential to follow the treatment plan as directed by a healthcare provider to manage symptoms effectively.

The differential diagnosis of adrenal cortical hypofunction, also known as adrenal insufficiency, involves a range of conditions that can present with similar symptoms and signs.

Common Differential Diagnoses

• Bronchogenic carcinoma: This type of lung cancer can cause adrenal insufficiency due to the production of ectopic ACTH (adrenocorticotropic hormone) by the tumor cells [7].
• Hemochromatosis: A genetic disorder that leads to iron overload, which can cause adrenal insufficiency due to the deposition of iron in the adrenal glands [7].
• Pituitary disorders: Such as hypopituitarism or pituitary tumors, which can lead to decreased production of ACTH and subsequent adrenal cortical hypofunction [5, 15].

Other Differential Diagnoses

• Adrenal gland disorders: Such as Cushing's syndrome (excess cortisol production) and Addison's disease (primary adrenal insufficiency) [8, 9].
• Hypothalamic-pituitary-adrenal axis disturbance: This can lead to decreased production of ACTH and subsequent adrenal cortical hypofunction [14].

Important Considerations

• The differential diagnosis of adrenal cortical hypofunction can be challenging due to the non-specific nature of early symptoms, such as fatigue and lassitude [12].
• A comprehensive evaluation, including laboratory tests and imaging studies, is often necessary to establish a definitive diagnosis [13].
