Adrenal Function in Critical Illness
Adrenal Function in Critical Illness

An appropriate hypothalamic-pituitary-adrenal (HPA) axis response is required to survive critical illness. Primary adrenal insufficiency, relative adrenal insufficiency, tissue resistance to glucocorticoids, ACTH deficiency and immune-mediated inhibition of the HPA axis may impair the secretion or action of glucocorticoids in critically ill patients. Adrenal insufficiency is estimated to occur in up to 77% of critically ill patients, but currently, there is no consensus on the diagnostic criteria for adrenal insufficiency in this setting, and standard testing does not discriminate among the aforementioned factors. We will study the incidence and natural history of adrenal insufficiency in critically ill patients to further define adrenal insufficiency and provide data to develop diagnostic tests. Clinical features and outcomes will be correlated with laboratory measurements of hormones, cytokines and glucocorticoid action. Healthy volunteers will undergo cortrosyn tests with measurement of free cortisol levels to develop a normative range for this endpoint.

< TAB>

Previous glucocorticoid use, if prolonged and supraphysiologic, also inhibits the HPA and can result in adrenal insufficiency. Patients with short intermittent courses of glucocorticoid administration have not been studied well, and may also be at risk. To gain further information about this group, patients receiving pulse glucocorticoid doses as part of bone marrow transplant regimens at the Clinical Center will also be studied.

Healthy volunteers will undergo cortrosyn tests with measurement of free cortisol levels to develop a normative range for this endpoint. Patients with known adrenal insufficiency will also be studied to help determine the clinical utility of diagnostic tests among these different groups.

  • Leukopenia (WBC count less than 4000 uL)
  • Normal WBC count with greater than 10 percent immature forms
  • Plasma C-reactive protein greater than 2 SD above the normal value
  • Plasma procalcitonin greater than 2 SD above the normal value

Hemodynamic variables

  • Arterial hypotension (SBP less than 90mm Hg, MAP less than 70, or an SBP decrease greater than 40 mm Hg in adults or less than 2 SD below normal for age)
  • SvO2 greater than 70 percent
  • Cardiac Index greater than 3.5L min(-1) M(-23)

EXCLUSION CRITERIA:

Pregnancy

Age less than 15 years at the Clinical Center; age less than 18 years at Georgetown or Suburban Hospitals

On glucocorticoids or megace within two weeks of admission unless using more than one of the following medications, patients taking inhaled corticosteriods (less than 1.5 mg/day budesonide, beclomethasone dipropionate and triamcinolone acetonide and less thab 0.75 mg/day for fluticasone propionate) or intranasal corticosteriods will not be excluded.

Patients who have received chronic steroid suppressive medications, i.e. etomidate, ketoconazole (Patients receiving etomidate for intubation purposes as a one time dose will not be excluded)

End stage renal or liver disease (creatinine clearance estimated as less than 20 cc/min by the cockcroft-gault equation: (140 - age) times lean body weight (kg)/ pCr (mg/dl) times 72, in patients with stable renal function; patients requiring dialysis; acute or fulminant hepatitis, alcoholic hepatitis, chronic severe hepatitis, severe obstructive hepatitis, severe coagulopathy, extrahepatic manifestations of ESLD, i.e. hypoxia, cardiomyopathy, acute renal failure)
