Addison's disease — Clinical Guidelines

Overview

Addison's disease, also known as primary adrenal insufficiency, is a rare autoimmune disorder characterized by inadequate production of cortisol and often aldosterone by the adrenal glands, leading to adrenal insufficiency 8.

Diagnosis

Clinical Features: Hyperpigmentation, fatigue, weight loss, hypotension, hyperpigmented scars, and salt craving 17.

Laboratory Tests: Hyponatremia, hyperkalemia, elevated ACTH levels, and low cortisol levels (especially on stimulation tests like ACTH stimulation test) 14 18.

Imaging: Abdominal imaging may show atrophic or enlarged adrenal glands 30.

Autoantibodies: Presence of adrenal cortex antibodies can support the diagnosis 8 35.

Management

Glucocorticoids: Replacement therapy with hydrocortisone or equivalent (dose adjusted based on individual needs) 13.

Mineralocorticoids: Fludrocortisone for aldosterone deficiency 13.

Sodium Supplementation: During acute illness or "sick day rules," increased sodium intake and possibly additional hydrocortisone 13.

Vitamin D: High-dose vitamin D therapy may modulate immune response and potentially benefit immune dysregulation 6 7.

Special Populations

Pregnancy: Adequate glucocorticoid and mineralocorticoid replacement is crucial; monitor closely for adrenal crisis 25 32.

Pediatrics: X-linked congenital forms exist, requiring early diagnosis and management 34.

Comorbidities: Concurrent conditions like thyrotoxicosis can complicate management; treat underlying conditions to prevent adrenal crises 23.

Key Recommendations

Initiate glucocorticoid replacement therapy with hydrocortisone or equivalent to maintain normal cortisol levels (Evidence: Strong 13).

Monitor and adjust mineralocorticoid therapy with fludrocortisone to manage electrolyte imbalances, particularly hyponatremia and hyperkalemia (Evidence: Strong 13).

Educate patients on "sick day rules" for managing acute illnesses to prevent adrenal crisis (Evidence: Moderate 13).

Consider high-dose vitamin D therapy in selected cases to potentially modulate immune response, though evidence is preliminary (Evidence: Weak 6 7).

Regularly assess and manage comorbidities, especially thyrotoxicosis, to prevent adrenal crisis exacerbations (Evidence: Moderate 23).
