Measuring markers of bone injury in the blood can help predict the likelihood of a cranial lesion and determine the need for head computed tomography, in cases of traumatic brain injury. The results of a new study comparing the usefulness of two biomarkers released into the blood following a TBI are presented in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
The article "GFAP Out-Performs S100ß in Detecting Traumatic Intracranial Lesions on Computed Tomography in Trauma Patients with Mild Traumatic Brain Injury and Those with Extracranial Lesions," describes a study of adult trauma patients with and without mild or moderate TBI.
The authors, Linda Papa and colleagues from Orlando Regional Medical Center, North Florida Veteran's Health System and University of Florida (Gainesville), University of Central Florida (Orlando), Banyan Biomarkers Inc. (Alachua, FL), Virginia Commonwealth University (Richmond, VA), and Baylor College of Medicine (Houston, TX), showed that increased blood levels of glial fibrillary acidic protein (GFAP) following TBI was a good predictor of intracranial lesions, whether or not the patient had fractures elsewhere in the body. Whereas S100ß levels in the blood of were significantly higher in trauma patients with fractures than without fractures, it was not as useful as GFAP in distinguishing between intracranial and extracranial lesions.
