Adrenal insufficiency, common in critical illness, presents as refractory hypotension. Early diagnosis and glucocorticoid treatment, like hydrocortisone, improve patient outcomes.

Area of Science:

  • Critical Care Medicine
  • Endocrinology
  • Internal Medicine

Background:

  • Adrenal insufficiency is a frequent, often overlooked condition in critically ill patients.
  • Acquired forms typically resolve upon successful treatment of the primary illness.

Purpose of the Study:

  • To highlight the significance of diagnosing adrenal insufficiency in intensive care unit (ICU) settings.
  • To emphasize the benefits of glucocorticoid therapy for improving outcomes in these patients.

Main Methods:

  • Diagnosis is typically established via a stress cortisol level.
  • The low-dose corticotropin stimulation test is used for definitive diagnosis when stress levels are uncertain.
  • A therapeutic trial of hydrocortisone is initiated for suspected cases while awaiting test results.

Main Results:

  • Refractory hypotension requiring vasopressors is the hallmark presentation in the ICU.
  • Prompt diagnosis and treatment with glucocorticoids are associated with improved outcomes.

Conclusions:

  • Adrenal insufficiency requires timely diagnosis and management in critically ill patients.
  • Glucocorticoid treatment is crucial for improving outcomes in patients with adrenal insufficiency.
