Clinical approach to adrenal insufficiency

Abstract

Adrenal insufficiency refers to inadequate production of glucocorticoids, mineralocorticoids, or both by the adrenal glands. This may  result from dysfunction or complete destruction of the adrenal cortex (primary adrenal insufficiency), inadequate adrenocorticotropic hormone production by the pituitary (secondary adrenal insufficiency), or inadequate corticotropin-releasing hormone production by the  hypothalamus (tertiary adrenal insufficiency). Diagnosis of adrenal insufficiency requires a high index of suspicion because of its  nonspecific signs and symptoms. It is associated with a high morbidity and low quality of life even in patients on treatment. When it  presents as adrenal crisis it has a high mortality. Glucocorticoid replacement is the mainstay of management, and this may be combined with mineralocorticoids in the case of primary adrenal insufficiency. Health care personnel must be reminded of this condition, to  improve rates of early diagnosis and improve outcomes in management. In this review, we also look at the management of adrenal  insufficiency in special populations and the potential role of newer longacting steroids in the management of adrenal insufficiency is  briefly discussed.
