The authors report the clinical course and immune system response of a patient with disease-associated recurrent transverse myelitis (TM) following cerebral infection with Brucellosis melitensis. The patient suffered four recurrences of his TM (each at a distinct spinal cord level) over the course of 2 years following his initial presentation, which ultimately progressed to quadriplegia. He had progressively declining cerebrospinal fluid (CSF) brucella antibody titers, suggesting a postinfectious, rather than an infectious, etiology. The authors simultaneously examined the expression of multiple cytokines in the CSF of this patient using cytokine antibody arrays and found a marked elevation of interleukin (IL)-6, IL-8, and macrophage chemoattractant protein (MCP)-1 levels relative to controls. Quantitative enzyme-linked immunosorbent assay (ELISA) analysis of the CSF confirmed a 1700-fold elevation of IL-6 and more modest elevations of IL-8 and MCP-1. IL-6 levels returned to baseline following treatment of the patient with intravenous cyclophosphamide and plasma exchange and the patient experienced a significant and sustained recovery of function.
