title: Evaluation of central nervous system vaccinia antibody synthesis in multiple sclerosis patients.
abstract: A serum/cerebrospinal fluid (CSF) ratio method was used to determine whether elevated CSF vaccinia antibody titers in some patients with multiple sclerosis are the result of central nervous system antibody synthesis or of a leak in the blood-brain barrier. Nine of 20 multiple sclerosis patients were noted to have a depressed serum/CSF vaccinia antibody ratio and a normal ratio for poliovirus-I, an agent thought not to be involved in the pathogenesis of multiple sclerosis. These data suggest central nervous system synthesis of vaccinia neutralizing antibody. Vaccinia virus antigens may play an important direct or indirect role in the pathogenesis of multiple sclerosis.
