The purpose of the study is to detect the presence of autoantibodies and autoantigens in cerebrospinal fluid early (<48 hours) following spinal cord trauma.

The study also aims to define the central or peripheral origin of autoantibodies by looking for their simultaneous presence at the blood level and to evaluate the prognostic value of the presence of autoantibodies within the cerebrospinal fluid, as well as on the initial clinical severity than on the recovery potential.

5. Immunosuppressive therapy or long-term corticosteroid therapy
