RESUMO
BACKGROUND: Spinal cord injury (SCI) can result in lifelong disability. Currently, the literature suggests that biomarkers are helpful in prognosticating SCI, but there is no specific biomarker to date. This is the first study that predicted the prognosis dynamically using biomarkers. AIM: To elucidate the role of biomarkers in prognosticating acute traumatic SCI. METHODS: Blood samples were obtained from 35 patients of acute traumatic SCI at presentation, immediate post-op, and at 6 weeks. At 6 months follow-up, patients were divided into two groups, i.e, improved and non-improved based on the improvement in the ASIA grade compared to presentation. A non-parametric test was used for comparing mean NSE, MMP-2, S100-B, and NF serum levels at presentation, immediate post-op, and 6 weeks post-op follow-up between the two groups. RESULTS: There was a significant difference (p = 0.03) in the NF values at presentation between the two groups. The difference of NSE values at 6 weeks was also significant (p = 0.016) between the two groups. S-100B levels were also significantly different between both groups at presentation (p=0.016), and at the immediate post-op stage (p=0.007). MMP-2 levels neither displayed any specific trend nor any significant difference between the two groups. CONCLUSION: Higher NF values at presentation, and higher S-100B levels at presentation and immediate post-operative period correlated with poor outcome. Also, increased NSE values after surgery are indicative of no improvement. These levels can be used at various stages to predict the prognosis. However, further studies are required on this topic extensively to know the exact cut-off values of these markers to predict the prognosis accurately.
