Addison disease: early detection and treatment principles

Area of Science:

• Endocrinology
• Autoimmunology

Background:

• Primary adrenal insufficiency, commonly known as Addison disease, stems from autoimmune adrenalitis, causing adrenal cortex destruction.
• This destruction leads to deficiencies in essential hormones like glucocorticoids, mineralocorticoids, and adrenal androgens.
• With a prevalence of 1 in 20,000, Addison disease requires high clinical suspicion to prevent misdiagnosis and potentially fatal adrenal crises.

Purpose of the Study:

• To highlight the causes, clinical manifestations, diagnostic methods, and management strategies for primary adrenal insufficiency.
• To emphasize the importance of early diagnosis and appropriate treatment to avoid adrenal crisis.
• To underscore the need for monitoring concomitant autoimmune disorders in patients with Addison disease.

Main Methods:

• Review of clinical manifestations including hyperpigmentation, fatigue, anorexia, orthostasis, nausea, pain, and salt craving.
• Diagnostic confirmation through the cosyntropin stimulation test when primary adrenal insufficiency is suspected.
• Treatment involves mineralocorticoid and glucocorticoid replacement, with stress-dose glucocorticoids during critical periods.

Main Results:

• Decreased cortisol and increased adrenocorticotropic hormone levels are key indicators.
• Subtle early symptoms can precede a life-threatening adrenal crisis.
• Patients require lifelong hormone replacement and monitoring for other autoimmune conditions.

Conclusions:

• Autoimmune adrenalitis is the primary cause of Addison disease, necessitating prompt diagnosis and management.
• Vigilance for associated autoimmune diseases is critical, as up to 50% of patients develop additional autoimmune disorders.
• Effective management includes hormone replacement therapy and preparedness for increased glucocorticoid needs during physiological stress.
