Objectives: the aim of our study was to investigate whether the presence of IgG-NMO antibody is associated with a different pattern of response at visual evoked potentials (VEPs) in patients affected by neuromyelites optica spectrum of disorders (NMOsd) with optic neuritis (ON). Methods: we retrospectively studied clinical, immunological and neurophysiological data from 28 patients affected by NMOsd who presented at least one optic neuritis (16 patients bilateral and 12 unilateral).

Background: Neuromyelitis optica (NMO) is an aggressive devastating autoimmune disorder affecting predominantly optic nerves and the spinal cord. We are able to assess the serum antibodies against aquaporin 4 (anti-AQP4 Ab, also known as NMO-IgG), which are highly sensitive and specific for NMO.

BACKGROUND: Neuromyelitis optica (NMO) is a disease of the CNS characterized by severe optic neuritis and longitudinally extended transverse myelitis. Recent studies suggest that anti-aquaporin-4 (AQP4) antibodies, NMO-specific biomarkers, are pathogenic and target AQP4-expressing astrocytes in NMO, although an additional event (T-cell response or infection) should occur for anti-AQP4 antibodies and complements to pass through the blood-brain barrier and cause the CNS lesions

There are two distinct subtypes of multiple sclerosis (MS) in Asians: opticospinal (OSMS) and conventional (CMS). OSMS has similar features to neuromyelitis optica (NMO) and half of OSMS patients have the NMO-Immunoglobulin G (IgG)/ anti-aquaporin-4 (AQP4) antibody.

Abstract Background: Neuromyelitis optica (NMO, Devic syndrome) is an inflammatory disorder of the central nervous system of putative autoimmune etiology that primarily affects the optic nerves and spinal cord. NMO is frequently associated with immunoglobulin G (IgG) antibodies to aquaporin-4 (AQP4-IgG), which are thought to be involved in the pathogenesis of the disease

A full-term female neonate was born with severe hypotonia and weakness. Her mother had been treated for neuromyelitis optica (Devic disease) for 6 years

The detection of antibodies against aquaporin-4 (AQP4) has improved the diagnosis of neuromyelitis optica (NMO). We evaluated a recently established cell-based anti-AQP4 assay in 273 patients with inflammatory CNS demyelination. The assay had a specificity of 99% and a sensitivity of 56% to detect all NMO patients and of 74% to detect the recurrent NMO patients, similar to the initial studies reported.

BACKGROUND: Severe visual loss is seen in both multiple sclerosis-associated optic neuritis (ON) and neuromyelitis optica (NMO)-associated ON.

Neuromyelitis optica (NMO) is an uncommon idiopathic demyelinating disease of the central nervous system and is sometimes unresponsive to steroid treatment as compared to multiple sclerosis (MS). There are only a few reports of plasma exchange (PE) as an effective rescue treatment when high-dose steroid therapy fails in exacerbations of NMO.

Background: Neuromyelitis optica (NMO) is a demyelinating disorder involving optic neuritis and transverse myelitis.

The antibody suspension bead array technology has been shown to be highly applicable for discovery of potential biomarkers in blood derived samples [1]. For analysis in neurodegenerative disorders like multiple sclerosis (MS), cerebrospinal fluid (CSF) is another highly interesting body fluid for protein profiling efforts [2].
