OBJECTIVES To analyze aquaporin-4 (AQP4) antibody-positive patients who do not fulfill the current diagnostic criteria of neuromyelitis optica (NMO) and NMO spectrum disorders (NMOSD). METHODS We used a cell-based assay (CBA) with AQP4-transfected cells to detect AQP4 antibody in 298 consecutive patients with inflammatory CNS disorders seen at Tohoku University Hospital from 2007 to 2012. The...
Typical NMO is characterized by simultaneous or sequential acute transverse myelitis and optic neuritis. Spinal cord lesions extending over 3 or more vertebral segments and normal brain imaging are the typical MRI findings in NMO. In typical cases with positive NMO antibody the diagnosis is easy but in seronegative and atypical cases with different clinical manifestations and MRI features the d...
Neuromyelitis optica (NMO) is an inflammatory demyelinating disease that typically affects optic nerves and spinal cord. Its pathogenic relationship to multiple sclerosis (MS) is uncertain. Unlike MS, NMO lesions are characterized by deposits of IgG and IgM co-localizing with products of complement activation in a vasculocentric pattern around thickened hyalinized blood vessels, suggesting a pa...
OBJECTIVE Severe inflammation and astrocyte loss with profound demyelination in spinal cord and optic nerves are typical pathological features of neuromyelitis optica (NMO). A diagnostic hallmark of this disease is the presence of serum autoantibodies against the water channel aquaporin-4 (AQP-4) on astrocytes. METHODS We induced acute T-cell-mediated experimental autoimmune encephalomyelitis...
IMPORTANCE Aquaporin 4 antibody (AQP4-Ab)-negative patients with longitudinally extensive transverse myelitis (LETM) behave differently from those with AQP4-Ab. Aquaporin 4 antibody-negative neuromyelitis optica (NMO) is rare when good assays are used. OBJECTIVE To assess if AQP4-Ab-negative patients with LETM share similar disease characteristics with AQP4-Ab-positive patients or whether the...
BACKGROUND Neuromyelitis optica (NMO) is an auto-immune disease that can cause severe visual and mobility impairments. Research on health-related quality of life (HRQoL) in NMO is scarce, limiting knowledge on factors influencing HRQoL and support needs. AIM This study provides the first qualitative exploration of HRQoL in NMO, conducted to provide a conceptual framework for the development o...
BACKGROUND Neuromyelitis optica (NMO) is a serious inflammatory demyelinating disease (IDD), characterized by the inflammation and demyelination of optic nerves and spinal cords, which subsequently leads to the loss of function. In a previous genome-wide association study, cluster of differentiation 58 (CD58) region was found to be susceptible for the risk of multiple sclerosis (MS) in Caucasia...
Neuromyelitis optica (NMO), or Devic's syndrome, is an autoimmune central nervous system demyelinating disorder primarily affecting the spinal cord and the optic nerves. It is characterized by the presence of NMO antibodies, alongside clinical and radiological findings. NMO and NMO-spectrum disorders (NMO-SD) have been reported in autoimmune disorders, and are infrequently described as a parane...
Neuromyelitis optica (NMO) is an inflammatory disease of the central nervous system characterized by severe optic neuritis and transverse myelitis, usually with a relapsing course. Aquaporin-4 antibody is positive in a high percentage of NMO patients and it is directed against this water channel richly expressed on foot processes of astrocytes. Due to the severity of NMO attacks and the high ri...
Neuromyelitis optica (NMO) is a distinct clinical entity from multiple sclerosis with its own clinical, laboratory and pathological characteristics. Definitive diagnosis of NMO is challenging at times as there can be a long interval between the occurrence of the index event and other neurological deficits which would fulfill the diagnostic criteria. Detection of NMO antibody could serve as an e...
