CAMPER

Study Summary

The University of British Columbia and the Rick Hansen Institute have collaborated to implement the multicenter study, CAMPER. Approximately 100 patients (15 at the University of California, San Francisco) with acute traumatic cervical and thoracic spinal cord injuries (SCI) are anticipated to enroll within 48 hours of their injury. The purpose of this study is to enhance neurologic outcome of individuals with SCI by improving acute clinical care and to establish biomarkers of injury severity. A lumbar intrathecal catheter will be inserted pre-operatively for the measurement of intrathecal pressure (ITP) and the collection of cerebrospinal fluid (CSF) samples. Spinal cord perfusion pressure (SCPP) will be calculated as the difference between mean arterial pressure (MAP) and the ITP.

CSF samples will be obtained from the intrathecal catheter to analyze the expression of the following biochemical markers: including interleukin (IL)-6, IL-8,  monocyte chemo-attractant protein (MCP)-1, glial fibrillary acidic protein (GFAP), S100B, and tau.  The objectives of this aspect of the study will be twofold. First, we will evaluate the accuracy of these inflammatory and neuronal markers at classifying the initial severity of paralysis and at predicting the extent of neurologic recovery. Second, we aim to characterize the temporal pattern of expression of these proteins to provide a more complete description of the human pathophysiology of SCI
