RESUMO
BACKGROUND: Guidelines do not suggest the routine use of methylprednisolone (MP) in patients with acute traumatic spinal cord injury (SCI). We tested the hypothesis regarding whether combination therapy with ceftriaxone and MP is superior to MP monotherapy in patients with acute traumatic SCI. METHODS: In a randomized, triple-blind clinical trial, 60 patients with acute (first 8 hours of the injury) traumatic SCI were enrolled at the Tabriz University of Medical Sciences, Tabriz, Iran, between December 2016 and June 2017. Accordingly, the patients were randomly divided into 2 case and control groups (n = 30 each). Upon admission, all included patients received a bolus dose of MP at 33 mg/kg intravenously (IV) for 15 minutes. Then, after 45 minutes, MP infusion was continued for 24 to 48 hours at a 5.4 mg/kg IV dose. The case group received an additional dose of ceftriaxone at 1 g 2 times a day for 7 days through an IV route. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were checked and compared between case and control groups upon admission and on the fourth and eighth days. Also, sensory and motor functions were evaluated according to the American Spinal Injury Association (ASIA) grading score upon admission, on the third and seventh days, upon discharge and 6 months after admission. RESULTS: Analyses showed a significant statistical difference between groups in the changes in CRP levels during days 1 and 4 (P = .001) and also during days 4 and 8 (P = .001). However, no significant statistical difference was detected in ESR levels changes between groups during days 1 and 4 (P = .073), and during days 4 and 8 (P = .069). ASIA scale was found to be significantly different between the MP plus ceftriaxone group and MP monotherapy upon admission and 6 months after treatment (P = .001 for both comparisons). However, the number of variations in the ASIA score had no significant statistical difference between groups 6 months after intervention (P = .465). CONCLUSION: The addition of ceftriaxone to the routine therapeutic protocol of acute SCI is accompanied by improved inflammation markers and functional outcomes 6 months after the intervention.
