INTRODUCTION Animal models of neuromyelitis optica (NMO) are needed for drug testing and evaluation of NMO disease pathogenesis mechanisms. RESULTS We describe a novel passive-transfer model of NMO in which rats made seropositive for human anti-aquaporin-4 (AQP4) immunoglobulin G antibody (NMO-IgG) by intraperitoneal (IP) injections were subject to intracerebral needle injury. Following a sin...
W hat is the most important moment in the history of a disease? Let us consider neuromyelitis optica (NMO), which was coined by French neurologist Eugene Devic in 1894 for a disease believed until recently to be a subtype of multiple sclerosis (MS). The discovery (in 2004) of a disease-specific biomarker for NMO revolutionized our understanding of both NMO and MS (1). In PNAS, Hinson et al. (2)...
BACKGROUND Optic neuritis (ON) may occur in isolation or may herald multiple sclerosis (MS) or neuromyelitis optica (NMO). Occasionally, ON may recur many times without intervening evidence of dissemination in space. OBJECTIVE To define the clinical course and prognosis of patients with recurrent ON. DESIGN Retrospective medical record review and telephone follow-up survey. SETTING Clinic...
We reviewed and compared the neuropathology of multiple sclerosis (MS), neuromyelitis optica (NMO), neuromyelitis optica spectrum disorders (NMOSD) and acute disseminated encephalomyelitis (ADEM) in Japan. Demyelinating lesions of MS are well circumscribed as compared with the lesions of NMO and NMOSD, which reveal variable, irregularly shaped and ill-defined borders that extend longitudinally ...
Neuromyelitis Optica (NMO) is an autoimmune demyelinating disease, characterized by the presence of autoantibody (NMO-IgG) to Aquaporin-4 (AQP4). NMO-IgG identification supports NMO diagnosis and several diagnostic tests have been developed, but their sensitivity is too variable, and some assay show low sensitivity. This impairs correct diagnosis of NMO. By cell based assay (CBA) we here evalua...
BACKGROUND Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease of the CNS in which a pathogenic role of anti-aquaporin-4 (AQP4) antibodies has been suggested. Although AQP4 is expressed in human cortex, recent histologic studies have failed to find any evidence of cortical demyelination in NMO. OBJECTIVE To evaluate, in vivo, the occurrence of focal and diffuse cortical ...
Neuromyelitis optica (NMO) is an aggressive demyelinating disease that typically affects the optic nerves and spinal cord. While it is increasingly recognized that cerebral lesions are common in NMO, there have been no reported cases of NMO presenting with psychiatric symptoms and polydipsia. We describe a patient with classic signs and symptoms of NMO who also demonstrated prominent psychiatri...
Neuromyelitis optica (NMO) is clinically characterized by severe optic neuritis and transverse myelitis. In Japan, NMO has been named optic-spinal multiple sclerosis (OSMS) and it has been thought to be a subtype of multiple sclerosis (MS). However, several clinical and laboratory findings suggest NMO or OSMS is distinct from MS. Recently, the disease-specific antibody (NMO-IgG) was found in th...
OBJECTIVE Neuromyelitis optica (NMO) is an autoimmune disease of the CNS, which resembles multiple sclerosis (MS). NMO differs from MS, however, in the distribution and histology of neuroinflammatory lesions and shows a more aggressive clinical course. Moreover, the majority of NMO patients carry IgG autoantibodies against aquaporin-4 (AQP4), an astrocytic water channel. Antibodies against AQP4...
Neuromyelitis optica (NMO) is an inflammatory demyelinating disease characterized by antibodies against aquaporin-4 in up to 80% of the cases and even less in the NMO spectrum disorders, which may be difficult to distinguish from early multiple sclerosis. While immunosuppressive therapy should be introduced in definite NMO, treatment strategies of NMO spectrum disorders are less clearly defined...
