La déféroxamine dans le traitement de l'hémorragie sous-arachnoïdienne anévrismale (aSAH) (DISH)
La déféroxamine dans le traitement de l'hémorragie sous-arachnoïdienne anévrismale (DISH)
Aneurysmal subarachnoid hemorrhage (aSAH) has a high incidence of mortality and significant morbidity, with mortality exceeding 30% in the first two days.The initial injury is related to increasing intracranial pressure, cerebral edema, and neuronal injuries associated with the release of iron. Iron has been shown to increase the incidence of cerebral edema, ischemia, and formation of hydrocephalus. Deferoxamine mesylate (DFO), a hydrophilic chelator, creates a stable complex with free iron thus preventing the formation of iron related free radicals.
This trial will evaluate the safety and efficacy of clinical deferoxamine for the treatment of aSAH for patients that are admitted to the hospital at the University of Michigan. Eligible participants will be enrolled and randomized to 1 of 2 doses of Deferoxamine or placebo (saline). Information regarding the patients will be collected and followed for up to 6 months post discharge.

Intervention / Traitement |
|---|---|
|
Expérimental: Deferoxamine lower dose
Deferoxamine 32 Milligram Per Kilogram (mg/kg) |
There will be 3 doses given to the patients days 1-3. Dose will be given intravenous with a fixed rate of 7.5 milligram per kilogram per hour (mg/kg/hr). The second dose will be given 24 hours after the first dose, and the third dose will be given 48 hours after the initial dose. Patients will be randomized to 32 mg/kg or 48 mg/kg of Deferoxamine.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Utility-weighted modified Rankin Scale (UW-mRS) at 6 months
Délai: 6 months (after hospital discharge)
|
Overall a Bayesian, longitudinal model will be used, this will be adjusted for baseline expected 6 month mRS using the FRESH score. At baseline, the expected 6 month UW-mRS (based on prognostic variables such as age and Hunt Hess) will be entered as the first value for the patient. Therefore, patients with greater severity at baseline, who achieve excellent outcomes will contribute a larger treatment effect. Similarly, patients with greater severity who have disability, but perform better than expected can still contribute useful information. |

Montreal Cognitive Assessment (MOCA)
Délai: At discharge from hospital (approximately 3-4 weeks)
|
Montreal cognitive assessment is a rapid sensitive screening tool for assessment of impaired cognitive function. The main domains of MoCA scale include attention, executive functions, memory, language, attention, naming, orientation, and visual-spatial ability. The total score is 30 points. A score of 25 points or less indicated impaired cognitive function. For patients with less than 12 years of education, one point was added to the total score. |
