Abstract
OBJECTIVE
To investigate secondary adrenal insufficiency post varying traumatic brain injuries' and its impact on prognosis.
METHODS
120 traumatic brain injury patients were categorized into mild, moderate and severe groups based on Glasgow Coma Scale. Adrenal function was evaluated through testing.
RESULTS
Secondary adrenal insufficiency rates were 0% (mild), 22.85% (moderate) and 44.82% (severe). Hypothalamus-pituitary-adrenal axis dysfunction rates were 14.81% (mild), 42.85% (moderate) and 63.79% (severe). Differences among groups were significant (p < .05). Patients with intact hypothalamus-pituitary-adrenal axis had shorter hospital stays and higher Glasgow Coma Scale scores. Receiver operating characteristic analysis of 24-h urinary free cortisol showed an area of 0.846, with a 17.62 μg/24h cutoff, 98.32% sensitivity and 52.37% specificity. In the low-dose adrenocorticotropic hormone test, with an 18 μg/dL cutoff, the receiver operating characteristic area was 0.546, with 46.28% sensitivity and 89.39% specificity.
CONCLUSION
As traumatic brain injury severity increases, secondary adrenal insufficiency incidence rises. The low-dose adrenocorticotropic hormone test is promising for hypothalamus-pituitary-adrenal axis evaluation. Patients with hypothalamus-pituitary-adrenal dysfunction experience prolonged hospitalization and worse prognosis.
