Management of Adrenal Crisis

Initial Emergency Management

• The American College of Physicians recommends administering hydrocortisone 100 mg IV bolus immediately without delay for further diagnostic testing in patients with adrenal crisis, particularly those with complex I deficiency presenting with hypotension, exhaustion, nausea, diarrhea, and elevated cortisol with ACTH of 16 1, 2
• Rapid IV fluid resuscitation with normal saline (1 L over the first hour, followed by 2-3 additional liters at a slower rate) is crucial in the initial management of adrenal crisis, as recommended by the American College of Emergency Physicians 1, 3
• Drawing blood for cortisol, ACTH, electrolytes, glucose, and tests for precipitating causes (e.g., infections) should be done without delaying treatment, as suggested by the American College of Physicians 2, 3
• Frequent monitoring of vital signs, particularly blood pressure and heart rate, is essential in the management of adrenal crisis, according to the American Heart Association 1

Continued Hospital Management

• The American College of Clinical Endocrinologists recommends continuing IV hydrocortisone at 50-100 mg every 6-8 hours for the first 24 hours in patients with adrenal crisis 4, 5
• Monitoring electrolytes, particularly sodium and potassium levels, is crucial in the continued hospital management of adrenal crisis, as recommended by the American College of Physicians 1, 6
• Evaluating for and treating the precipitating cause of adrenal crisis, likely infection given the diarrhea, is essential, according to the Infectious Diseases Society of America 2

Transition to Maintenance Therapy

• The American College of Clinical Endocrinologists recommends tapering stress-dose corticosteroids over 3-5 days after 24-48 hours of IV therapy and clinical improvement 1, 2
• Transitioning to oral maintenance therapy with hydrocortisone 15-20 mg daily in divided doses (typically 2/3 in morning, 1/3 in early afternoon) is recommended by the American College of Clinical Endocrinologists 5
• Assessing the need for mineralocorticoid replacement (fludrocortisone 0.05-0.1 mg daily) when hydrocortisone dose falls below 50 mg daily is essential, according to the American College of Clinical Endocrinologists 2, 5

Prevention of Future Adrenal Crises

• The American College of Clinical Endocrinologists recommends providing patient education on stress dosing during illness (typically 2-3 times maintenance dose) to prevent future adrenal crises 4, 5
• Prescribing an emergency injectable hydrocortisone kit and providing training on self-administration is crucial, as recommended by the American College of Emergency Physicians 1
• Recommending a medical alert bracelet or necklace for adrenal insufficiency is essential, according to the American College of Clinical Endocrinologists 4, 5

Monitoring Parameters

• Assessing clinical symptoms, such as energy level, appetite, and weight stability, is recommended by the American College of Physicians to monitor the effectiveness of treatment 6
• Monitoring blood pressure (including postural measurements) is crucial, as recommended by the American Heart Association 2, 6
• Checking electrolytes periodically is essential, according to the American College of Physicians 1, 6
• Considering morning cortisol measurements to evaluate the adequacy of replacement is recommended by the American College of Clinical Endocrinologists 5

Common Pitfalls to Avoid

• Delaying treatment while waiting for diagnostic confirmation can be fatal, as warned by the American College of Emergency Physicians 1, 2
• Inadequate fluid resuscitation alongside corticosteroid administration is a common pitfall, according to the American College of Physicians 1, 3
• Failing to identify and treat the precipitating cause of adrenal crisis is essential to avoid, as recommended by the Infectious Diseases Society of America 2
• Tapering corticosteroids too quickly before clinical stabilization is a common mistake, as warned by the American College of Clinical Endocrinologists 1, 5
• Overlooking the need for mineralocorticoid replacement in primary adrenal insufficiency is a pitfall, according to the American College of Clinical Endocrinologists 5, 6

Symptom Improvement Timeline After Initiating Corticosteroid Therapy in Acute Adrenal Insufficiency

Immediate Response and Critical Considerations

• Clinical improvement in severe symptoms, including altered mental status, nausea, vomiting, and profound weakness, typically begins within 24 hours of initiating stress-dose corticosteroids (hydrocortisone 50-100 mg IV every 6-8 hours) 7, 8
• If prednisone is used, it must be at stress doses (1-2 mg/kg daily for severe symptoms, or 20 mg daily for moderate symptoms) 7, 9

Transition and Maintenance Phase

• Stress-dose corticosteroids are typically tapered over 5-7 days once the precipitating illness resolves and the patient can tolerate oral medications 7, 8, 9
• For moderate symptoms (Grade 2), the taper occurs over 5-10 days from stress doses down to maintenance therapy 9
• Transition to oral maintenance therapy occurs once stress-dose tapering is complete, typically with hydrocortisone 15-25 mg daily in divided doses or prednisone 5-10 mg daily 7, 9
• Full clinical recovery and symptom resolution may take 1-2 weeks as patients transition from stress dosing to physiologic replacement 7, 8

Management of Acute Addisonian Crisis: Immediate Treatment and Mineralocorticoid Guidance

Immediate Management

• Administer a 100 mg intravenous bolus of hydrocortisone immediately, without awaiting diagnostic tests, as the first step in treating an acute Addisonian crisis. 10, 11
• Begin rapid isotonic saline infusion at ≈ 1 L per hour initially, followed by an additional 2–3 L over the next several hours to correct profound hypovolemia. 10, 11
• Continue intravenous hydrocortisone at 100 mg every 6–8 hours (or 100–300 mg/day as a continuous infusion) for the first 24–48 hours of resuscitation. 10
• Perform frequent hemodynamic monitoring to balance adequate volume replacement with avoidance of fluid overload. 10

Timing of Mineralocorticoid (Fludrocortisone) Replacement

• Restart fludrocortisone only after the hydrocortisone dose has been tapered below 50 mg/day during the recovery phase (typically after 24–48 hours). 10
• Adding fludrocortisone while patients are receiving stress‑dose hydrocortisone (≥50 mg/day) provides no additional benefit and may complicate fluid balance. 10

Transition to Maintenance Therapy

• Once hydrocortisone is ≤ 50 mg/day, re‑initiate fludrocortisone at 0.05–0.1 mg (50–100 µg) once daily. 10
• Taper stress‑dose hydrocortisone over 1–3 days to an oral maintenance regimen of 15–25 mg daily, divided into two or three doses. 10
• Adjust the fludrocortisone dose (typical range 50–200 µg daily) according to clinical parameters such as blood pressure, orthostatic symptoms, plasma renin activity, and electrolyte status. 10

Common Pitfalls to Avoid

• Do not delay hydrocortisone and fluid resuscitation to give fludrocortisone first; emergency treatment must precede any diagnostic or therapeutic procedures. 10, 11
• Do not treat the tachycardia seen in crisis with beta‑blockers or other rate‑control agents; the tachycardia resolves once volume and cortisol deficits are corrected. 10
• Avoid introducing fludrocortisone while hydrocortisone remains ≥ 50 mg/day, as this can cause hypokalemia or fluid retention without improving hemodynamics. 10
• Do not taper stress‑dose glucocorticoids before the underlying precipitating illness has resolved, to prevent recurrence of adrenal crisis. 10
