adrenal insufficiency in critical ill septic patients by random cortisol

Amir H Hamrahian, Maria Fleseriu
OBJECTIVE: The definition of normal adrenal function in critically ill patients remains controversial, despite a large body of literature. We review the clinical presentation, diagnosis, and treatment of adrenal insufficiency in critically ill patients and discuss the authors' personal approach to patient management. METHODS: Extensive literature review, guidelines from professional societies, and personal experience. RESULTS: A decrease in cortisol breakdown rather than an increase in cortisol production has been suggested as the main contributor to elevated cortisol levels in critically ill patients...

BACKGROUND AND OBJECTIVES: Corticosteroids were introduced in the treatment of severe infection as early as in the nineteen forties. Several " negative" randomized controlled trials of high-dose of glucocorticoids given for a short period of time in the early course of severe sepsis or acute respiratory distress syndrome raised serious doubts on the benefit of this treatment. Recently, a link between septic shock and adrenal insufficiency, or systemic inflammation induced glucocorticoids receptor resistance had been established...

OBJECTIVE: To develop consensus statements for the diagnosis and management of corticosteroid insufficiency in critically ill adult patients. PARTICIPANTS: A multidisciplinary, multispecialty task force of experts in critical care medicine was convened from the membership of the Society of Critical Care Medicine and the European Society of Intensive Care Medicine. In addition, international experts in endocrinology were invited to participate. DESIGN/METHODS: The task force members reviewed published literature and provided expert opinion from which the consensus was derived...

RATIONALE: Diagnosis of adrenal insufficiency in critically ill patients has relied on random or cosyntropin-stimulated cortisol levels, and has not been corroborated by a more accurate diagnostic standard. OBJECTIVE: We used the overnight metyrapone stimulation test to investigate the diagnostic value of the standard cosyntropin stimulation test, and the prevalence of sepsis-associated adrenal insufficiency. METHODS: This was an inception cohort study...

PURPOSE OF REVIEW: Adrenal insufficiency, common in critically ill patients of all ages, has recently gained prominence as a significant pathologic entity in pediatrics. This review describes the current diagnostic approach to detecting adrenal insufficiency and the clinical consequences in critically ill children and infants. It also discusses the current therapeutic approach to adrenal insufficiency in critically ill patients. RECENT FINDINGS: Relative adrenal insufficiency and its clinical implications have recently come into focus with observational studies demonstrating a high prevalence in pediatric septic shock patients and a significant associated morbidity...

CONTEXT: Activation of the hypothalamic-pituitary-adrenal (HPA) axis represents one of several important responses to stressful events and critical illnesses. Despite a large volume of published data, several controversies continue to be debated, such as the definition of normal adrenal response, the concept of relative adrenal insufficiency, and the use of glucocorticoids in the setting of critical illness. OBJECTIVES: The primary objective was to review some of the modulating factors and limitations of currently used methods of assessing HPA function during critical illness and provide alternative approaches in that setting...

Acute adrenal insufficiency has been demonstrated in a number of patients with shock. This study was designed to evaluate the rate of occult adrenal insufficiency in the critically ill trauma population and to determine the impact of hypoproteinemia on the use of random cortisol levels as a marker for adrenal insufficiency. Forty-four patients were prospectively enrolled on admission to the trauma intensive care unit, with three excluded, for a total n of 41. Random total serum cortisol and albumin levels were drawn on hospital Days 1, 4, 8, and 14...

It is unclear whether a random plasma cortisol measurement and the corticotropin (ACTH) test adequately reflect glucocorticoid secretory capacity in critical illness. This study aimed to determine whether these tests provide information representative of the 24 hour period. Plasma cortisol was measured hourly for 24 hours in 21 critically ill septic patients followed by a corticotropin test with 1 microg dose administered intravenously. Serum and urine were analysed for ACTH and free cortisol respectively. Marked hourly variability in plasma cortisol was evident (coefficient of variation 8-30%) with no demonstrable circadian rhythm...

In critically ill patients, the hypothalamic-pituitary-adrenal axis is usually activated, resulting in elevated plasma cortisol levels. This enables the human organism to cope with sepsis, trauma and other forms of stress. During critical illness, total adrenal insufficiency rarely occurs. On the other hand, septic shock can be accompanied by a relative deficit of cortisol. Causes of this relative adrenal insufficiency are a dysfunction of the hypothalamic-pituitary-adrenal axis and/or cortisol resistance. There are no strict biochemical criteria available to diagnose relative adrenal insufficiency; clinical observation is the decisive factor...
