Introduction
Adrenal crisis is characterized by an acute deterioration in health status due to a severe deficiency of the adrenal hormone cortisol[1]. It typically occurs in patients with known adrenal insufficiency, either primary (Addison's disease) or secondary, but can also be the first presentation of undiagnosed adrenal insufficiency[3].
Diagnosis
Diagnosing adrenal crisis can be challenging due to its nonspecific initial symptoms. Key aspects of diagnosis include:
Clinical Presentation: - Abdominal pain or flank pain - Confusion, loss of consciousness, or coma - Dehydration - Dizziness or lightheadedness - Severe fatigue and weakness - Hypotension (systolic blood pressure <100 mm Hg or ≥20 mm Hg lower than baseline) - Nausea and vomiting - Fever[1][2]
Laboratory Findings: - Hyponatremia - Hyperkalemia (in primary adrenal insufficiency) - Hypoglycemia - Metabolic acidosis[2]
Diagnostic Tests: - ACTH stimulation test - Cortisol level - Plasma ACTH level - Electrolyte panel[2]
It's crucial to note that diagnostic measures should never delay treatment if adrenal crisis is suspected[4].
Emergency Management
Prompt treatment is essential in managing adrenal crisis. The key steps include:
Glucocorticoid Administration: Immediate administration of hydrocortisone is the cornerstone of treatment.
Adults: 100 mg intravenous (IV) or intramuscular (IM) hydrocortisone, followed by 50 mg every 6 hours or a continuous infusion of 200 mg/24 hours[1][4].
Fluid Resuscitation: Rapid IV fluid administration to correct hypovolemia and hypotension.
Typically 1000 mL of isotonic saline in the first hour[1].
Electrolyte Correction: Address any electrolyte imbalances, particularly hyponatremia and hyperkalemia[2].
Glucose Administration: If hypoglycemia is present, administer IV glucose[1].
Treat Underlying Cause: Identify and treat any precipitating factors, such as infections[1].
Monitoring: Close monitoring of vital signs, electrolytes, and glucose levels[4].
Transition to Oral Therapy: Once the patient is stable, transition to oral glucocorticoid therapy[4].
Prevention
Prevention of future adrenal crises is crucial:
Patient education on stress dosing and sick day rules
Provision of emergency hydrocortisone injection kits
Issuing steroid emergency cards and medical alert bracelets
Regular follow-up with an endocrinologist[5]
Early recognition and prompt treatment of adrenal crisis are vital to prevent potentially fatal outcomes. Healthcare providers should maintain a high index of suspicion in at-risk patients presenting with suggestive symptoms.
