background: neuromyelitis optica (nmo) is an uncommon neuro- inflammatory syndrome that has shown to be distinct from multiple sclerosis (ms) and associated with the autoantibody marker nmo-immunoglobulin g (igg). there are still only a few studies regarding the epidemiology of nmo in iran. in the present study, we tried to describe the epidemiology of nmo in khuzestan as one of the densely pop...

Neuromyelitis optica is an inflammatory demyelinating disease (IDD) of the CNS, which mainly affects optic nerve and spinal cord. Autoantibodies against aquaporin-4 also known as NMO-IgG have been implicated in the pathogenesis of NMO. We evaluated the sensitivity and specificity of NMO-IgG assay for diagnosing NMO patients and differentiating them from MS patients and those with undifferentiat...

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 idiopathic inflammatory disorder of the central nervous system (CNS) that preferentially affects the optic nerves and spinal cord. In Asia, NMO has long been considered a subtype of multiple sclerosis (MS). However, recent clinical, pathological, immunological, and imaging studies have suggested that NMO is distinct from MS. This reconsideration of NMO was initi...

OBJECTIVE Neuromyelitis optica (NMO) is caused by binding of pathogenic autoantibodies (NMO-immunoglobulin G [IgG]) to aquaporin-4 (AQP4) on astrocytes, which initiates complement-dependent cytotoxicity (CDC) and inflammation. We recently introduced mutated antibody (aquaporumab) and small-molecule blocker strategies for therapy of NMO, based on prevention of NMO-IgG binding to AQP4. Here, we i...

OBJECTIVES Inflammatory demyelinating diseases of the CNS comprise a broad spectrum of diseases like neuromyelitis optica (NMO), NMO spectrum disorders (NMO-SD) and multiple sclerosis (MS). Despite clear classification criteria, differentiation can be difficult. We hypothesized that the urine proteome may differentiate NMO from MS. METHODS The proteins in urine samples from anti-aquaporin 4 (...
