Phase 3 Study of Hydrocortisone and Fludrocortisone in Glucocorticoid Insufficiency Related to Traumatic Brain Injury

Treatment of glucocorticoid insufficiency in TBI patients remains controversial.

The purpose of this study is to determine whether hydrocortisone associated with fludrocortisone decreases rate of hospital-acquired pneumonia on day-28 in TBI patients with glucocorticoid insufficiency. Glucocorticoid function will be assessed by a corticotropin test (ACTH 0.25 mg). The study treatment will be started before reception of the results of these test. Patients with glucocorticoid insufficiency (basal cortisolemia < 15 mcg/dl or post ACTH raise < or = 9 mcg/dl) will be treated for 10 days. Patients with adapted glucocorticoid function will no longer be treated till the results of corticotropin test are known.

The primary end point will be rate of HAP on day-28 in patients with glucocorticoid insufficiency. Secondary endpoints will be neurological recovery (on day-28, -6 and -12), mortality (on day-28 and day-365), rate of other infections (on day-28), rate of organ failures (on day-28), mechanical ventilation weaning time, ICU length of stay.

In a double-blinded fashion (randomized on a 1:1 basis), 326 patients receive 200 mg intravenously for 10 days. After 7 days, treatment will be tapered with 100 mg given intravenously for days 8-9, then 50 mg for day 10, and then stopped.

All concomitant treatments, including antibiotics, fluids, vasopressors and ancillary therapies will be given at the discretion of the primary care physician. Evidence-based guidelines for the management of severe trauma brain injury (J Neurotrauma 2007; 24 Suppl 1, S1-106.) are encouraged to be followed. All institution are level I trauma center and university hospital.
