Abstract

Highlights: A neuroprotective role for Atorvastatin in moderate to severe TBI is proposed. Atorvastatin improved functional outcomes at 3-months following moderate to severe TBI. Atorvastatin was not associated with reduction in the rate of brain contusion expansion in moderate and severe TBI. Abstract: The aim of the current study was to investigate the effects of atorvastatin on brain contusion volume and functional outcome of patients with moderate and severe traumatic brain injury (TBI). The study was conducted as a randomized clinical trial during a 16-month period from May 2015 and August 2016 in a level I trauma center in Shiraz, Southern Iran. We included 65 patients with moderate (GCS: 9–13) to severe (GCS: 5–8) TBI who had brain contusions of less than 30 cc volume. We excluded those who required surgical intervention. Patients were randomly assigned to receive daily 20 mg atorvastatin for 10 days (n = 21) or placebo in the same dosage (n = 23). The brain contusion volumetry was performed on days 0, 3 and 7 utilizing spiral thin-cut brain CT-Scan (1-mm thickness). The outcome measured included modified Rankin scale (MRS), Glasgow Outcome Scale (GOS) and Disability rating Scale (DRS) which were all evaluated 3 months post-injury. There was no significant difference between two study group regarding the baseline, 3rd day and 7th day of the contusion volume and the rate of contusion expansion. However, functional outcome scales of GOS, MRS and DRS at 3-months post-injury were significantly better in atorvastatin arm of the study compared to placebo (p values of 0.043, 0.039 and 0.030 respectively). Even though atorvastatin was not found to be more effective than placebo in reducing contusion expansion rate, it was associated with improved functional outcomes at 3-months following moderate to severe TBI.
