SEEN guidelines for the management and prevention of acute adrenal insufficiency.

Acute adrenal insufficiency (AAI) is a potentially fatal medical emergency whose prevention and treatment should be known by all medical professionals. AAI is an underdiagnosed condition because of its non-specific symptoms, but its diagnosis and early treatment with glucocorticoids is vital. It may be triggered by a de novo deficiency in cortisol synthesis or occur secondarily to omission of hormone replacement therapy (corticosteroids) or inadequate adjustment of the dose required in stress situations in patients previously diagnosed with adrenal insufficiency. AAI prevention significantly decreases death from cardiovascular diseases and infections in patients with adrenal insufficiency, and also improves their quality of life. Adequate education of patients, relatives, and all healthcare professionals is therefore essential. Therefore, the Adrenal Disorders Group of the Neuroendocrinology Area of the Spanish Society of Endocrinology and Nutrition (SEEN) has prepared, at the proposal of the SEEN's board, a guideline for optimal management of acute adrenal insufficiency. The guideline is intended to provide practical recommendations for all healthcare professionals who may be involved in the diagnosis, treatment, and prevention of AAI. It is also intended to provide patients and their families with action guidelines for AAI management and prevention.
