OBJECTIVE: To investigate the differential diagnostic value of NMO-IgG for neuromyelitis optica (NMO) versus multiple sclerosis (MS) and to analyze its possible clinical features related to NMO-IgG. METHODS: Forty-one NMO patients and 44 MS patients in acute phase and 40 healthy controls were investigated. Serum NMO-IgG was tested by indirect immunofluorescence assay.
Background: Recurrent myelitis (rM) represents a pathogenetically heterogeneous group of inflammatory diseases with a selective involvement of the spinal cord. The recent description of NMO Ig-G antibody, the specific biomarker for Neuromyelites Optica (NMO), also in patients with recurrent myelitis with longitudinally extensive transverse spinal cord lesions (LETM), has brought to consider this disease an incomplete form of NMO (NMO Spectrum of Disorders). Methods: we retrospectively selected patients (pts) with rM attended our neurological department between January 2000 and March 2010
OBJECTIVE: In the present study, we examined some demographic and clinical features of Turkish LDDD patients and we compared these features with Turkish conventional MS patients, on the basis of demographic, clinical and immunological features. BACKGROUND: So called limited disseminated demyelinating diseases (LDDDs) includes optic neuritis (ON), transverse myelitis (TM), optic-spinal multiple sclerosis (OSMS) and neuromyelitis optica (NMO). OSMS and NMO select the involvement of optic nerve and spinal cord more than conventional multiple sclerosis (CMS)
Background: Neuromyelitis optica (NMO) is an inflammatory idiopathic and usually relapsing disease of the central nervous system, with a characteristic predilection for the optic nerves and spinal cord. MS exhibits a higher prevalence in Caucasian populations, whereas NMO is relatively more frequent in non-Caucasian individuals – Asians, Hispanics and Africans. Brazilian population represents interethnic crossings between people from America, Africa and Europe.
Objective: To describe the clinical characteristics, course, and prognosis of optic neuritis in recurrent neuromyelitis optica.
