This comprehensive academic article, co-authored by Dr. Aaron Michels from the University of Colorado Denver and Dr. Nicole Michels, provides a detailed overview of primary adrenal insufficiency, known as Addison's disease. The paper focuses on autoimmune adrenatitis as the most common etiology in the developed world, outlining the stages of its pathogenesis from genetic predisposition to overt adrenal crisis. It details the subtle and often nonspecific clinical features, such as fatigue, anorexia, hyperpigmentation, and salt craving, which necessitate a high index of suspicion for diagnosis. The article thoroughly explains the diagnostic algorithm, centering on the cosyntropin stimulation test as the first-line confirmatory investigation, supported by measurements of adrenocorticotropic hormone, renin, and aldosterone levels. The core of the management discussion covers lifelong hormone replacement therapy, including glucocorticoid options like hydrocortisone or prednisone and the mineralocorticoid fludrocortisone, with titration guided by clinical symptoms and laboratory parameters. A critical component is patient education on stress-dose glucocorticoid adjustment during illness or procedures, and the need for emergency injectable steroids. The review also emphasizes the importance of lifelong vigilance for associated autoimmune disorders, such as thyroid disease, type 1 diabetes, and celiac disease, which occur in up to half of affected individuals.
