Biomarkers for Pain in Spinal Cord Injury (SCI) Patients
Sponsor: The University of Texas Health Science Center, Houston
Summary
The investigators propose to compare plasma protein profiles for SCI patients with/without chronic neuropathic pain in order identify biomarker(s) that are associated with this medical condition. Secondly, the investigators propose to identify a temporal relationship to initial SCI at which these biomarkers manifest. Our working hypothesis is that sustained alterations in specific inflammatory molecules are associated with chronic neuropathic pain following SCI, and that their plasma levels can serve as biomarkers to identify patients at risk for the development of neuropathic pain. Additionally the investigators are collecting skin tissue biopsy samples from patients following acute and chronic spinal cord injury to create vector-free human iPS cells from fibroblasts by direct delivery of reprogramming proteins.

Interventions
blood samples
Chronic patients - a one time blood sample (12 mL) and questionnaire; 10 subjects will donate a 3-5mm skin tissue sample. Longitudinal Patients - 5 blood samples (12 mL each, totaling 60 mL at the following time points: within 48 hours, one week, one month, 6 months and 18 months post injury to coincide with standard visits) and questionnaire. 10 subjects will donate a 3-5mm skin sample. Healthy, pain free volunteers - a one time blood sample (12 mL), vital signs per standard CRU protocol and questionnaire confirming they are healthy.
