- Cerebrospinal Fluid Aquaporin-4 Antibody Levels in Neuromyelitis Optica Attacks(2014) SATO, Douglas Kazutoshi; CALLEGARO, Dagoberto; JORGE, Frederico M. de Haidar; NAKASHIMA, Ichiro; NISHIYAMA, Shuhei; TAKAHASHI, Toshiyuki; SIMM, Renata Faria; APOSTOLOS-PEREIRA, Samira Luisa; MISU, Tatsuro; STEINMAN, Lawrence; AOKI, Masashi; FUJIHARA, KazuoTo elucidate immunopathogenetic roles of aquaporin-4 antibodies in the cerebrospinal fluid (CSF) of neuromyelitis optica spectrum disorders (NMOSD), we analyzed aquaporin-4 antibody titers, cellular and inflammatory markers in the CSF collected from 11 aquaporin-4 antibody seropositive patients. The CSF aquaporin-4 antibody levels during attacks (but not in sera) closely correlated with pleocytosis, inflammatory cytokines including interleukin-6 that can regulate antibody-producing plasmablasts, and glial fibrillary acidic protein levels in the CSF. The amount of aquaporin-4 antibodies present in the central nervous system may have therapeutic implications, as it is associated with astrocyte injury and inflammatory responses during NMOSD attacks.

No patients were positive for both antibodies. Patients with MOG antibodies represented 21.1% (16/76) of the patients negative for AQP4 antibodies. Compared with patients with AQP4 antibodies or patients who were seronegative, patients with MOG antibodies were more frequently male, had a more restricted phenotype (optic nerve more than spinal cord), more frequently had bilateral simultaneous optic neuritis, more often had a single attack, had spinal cord lesions distributed in the lower portion of the spinal cord, and usually demonstrated better functional recovery after an attack.Conclusions:Patients with NMOSD with MOG antibodies have distinct clinical features, fewer attacks, and better recovery than patients with AQP4 antibodies or patients seronegative for both antibodies.
