Adrenal insufficiency in acute spinal cord injury.
OBJECTIVE
A 21-year-old man with a C6 American Spinal Injury Association A spinal cord injury (SCI) developed symptomatic hypotension resistant to vasopressors and volume replacement 2 weeks after injury and was diagnosed with adrenal insufficiency by cosyntropin test. Adrenal insufficiency has been documented in chronic SCI; this case shows documented adrenal insufficiency in acute SCI.


METHODS
Case report.


RESULTS
Secondary adrenal insufficiency complicated the medical and rehabilitative course of this patient with SCI. During 2 infectious episodes, this patient's dosage of hydrocortisone had to be doubled to control symptomatic hypotension, lethargy, diffuse weakness, and anorexia.


CONCLUSIONS
The nonspecific symptomatology of adrenal insufficiency can be easily overlooked in patients with SCI. Low basal cortisol levels may be an important clue to this disorder. Low-dose adrenocorticotropic hormone stimulation may be more sensitive than high doses for detecting subclinical adrenal insufficiency. A high index of clinical suspicion is needed for the correct diagnosis of acute and chronic adrenal insufficiency.
