prognostic Serum Factors in Tranmatic Brain Injury: A Systematic Review

Background & Aim: Traumatic brain injury is one of the main causes of death and disability. The aim of this study isto systematically review the articles which assessed some serum factors of traumatic brain injury patients in relationto their outcomes.Methods & Materials/Patients: Databases were searched for relevant publications from 2005 to 2014. Selectioncriteria were:Studies which evaluate the factors affecting the outcome after TBI, TBI defined as acute changes inbrain function resulting in a strong external force to the head .Resultswere measured by Glasgow Outcome Score ora comparable measure.Factors were measured in first month after injury and the prognosis was addressed. All paperswere checked and approved by a specialist and expert in that field. A systematic review was performed for prognosticfactors.Results: Sixty-three studies were included. Most studies used Glasgow Outcome Score at 6 months post-injury asoutcome measure, sometimes in combination with other outcome measures. Strong evidence for predicting outcomewas found for serum concentration of S100 protein, NSE, MBP, NF-H, GFAP, UCH-L1, blood glucose levels, serumlevels of LDH, sodium level, prothrombin time, partial thromboplastin time, platelet count, D.dimer, HSP 70, serumlevels of IL-8, number of circulating EPCs, and DNA levels in serum. Moderate evidence for predicting outcome wasfound for high serum MMP9. Strong evidence of no association was found for WBC count and serum cortisol levels.Moderate evidence of no association was found for serum total cholesterol for other determinants, inconclusive or noevidence or limited evidence was found.Conclusion: S100 protein, NSE, MBP, NF-H, GFAP, UCH-L1, blood glucose levels, serum levels of LDH, sodiumlevel, prothrombin time, Partial thromboplastin time, platelet count, D.dimer, HSP 70, serum levels of IL-8, number ofcirculating EPCs, and DNA levels in serum predicted outcome after traumatic brain injury. WBC count, serum cortisollevels, total cholesterol and MMP9 did not have predictive value.
