Anti NMO neuritis

Yan Wu, Lianmei Zhong, Jia Geng
Neuromyelitis optica (NMO) and NMO spectrum disorders (NMOSD) have garnered attention due to their high pathogenicity, high risk of relapse, and poor prognosis as an inflammatory central nervous system (CNS) syndrome. There is a consensus that the anti-aquaporin-4 antibody (AQP4-IgG) is the main pathogen detectable in majority of NMOSD patients, including traditional NMO and AQP4-IgG-positive optic neuritis. In serum-negative NMOSD patients, myelin oligodendrocyte glycoprotein (MOG) antibodies are considered pathogenic factors...

Anti-myelin oligodendrocyte glycoprotein (MOG) antibodies (MOG-Abs) were first detected by immunoblot and enzyme-linked immunosorbent assay nearly 30 years ago, but their association with multiple sclerosis (MS) was not specific. Use of cell-based assays with native MOG as the substrate enabled identification of a group of MOG-Ab-positive patients with demyelinating phenotypes. Initially, MOG-Abs were reported in children with acute disseminated encephalomyelitis (ADEM). Further studies identified MOG-Abs in adults and children with ADEM, seizures, encephalitis, anti-aquaporin-4-antibody (AQP4-Ab)-seronegative neuromyelitis optica spectrum disorder (NMOSD) and related syndromes (optic neuritis, myelitis and brainstem encephalitis), but rarely in MS...

We report a case of neuromyelitis optica (NMO) that was diagnosed at the age of 90. After initially developing visual loss in the right eye, a patient was diagnosed with optic neuritis. Although treatment with methylprednisolone therapy provided relief, 3 months later she developed optic neuritis on the other side. Visual activity recovered after further administration of methylprednisolone. At the age of 91, she presented with muscle weakness of her left extremities. A cervical MRI revealed myelitis with a longitudinally extensive spinal cord lesion from the second to fifth cervical vertebrae...

BACKGROUND: Recent studies have suggested that anti-MOG antibodies and optic neuritis are associated and anti-MOG antibody positive patients have had better recoveries. The purpose of this study was to compare the clinical course and treatment outcome of MOG-Ab associated and non-MOG-Ab associated ON. METHODS: Patients diagnosed with optic neuritis were referred for brain and cervical MRI. Blood samples were also taken to measure MOG antibody and NMO antibody levels...

Background: Neuromyelitis optica (NMO) is an inflammatory demyelinating disease that selectively affects the optic nerves and spinal cord and generally follows a relapsing course. Therapeutic plasma exchange (TPE) appears to be effective in patients with central nervous system inflammatory demyelinating disease who do not respond to first-line corticosteroid treatment. Objective: We represent a retrospective review of the use of TPE in the treatment of an acute attack of NMO in five patients who failed to respond to initial immunomodulatory treatment...

The present report discusses the case of a woman with neuromyelitis optica (NMO) who exhibited bilateral optic neuritis, longitudinally extensive myelitis, serum anti-aquaporin-4 antibodies, and a unique pattern of white matter involvement. The disease duration was 26 years, and the patient died at the age of 65 years. Sequential magnetic resonance images obtained during the last 6 years of life revealed leukoencephalopathy-like lesions extending symmetrically and contiguously from the periventricular regions, which had begun to transform into multiple cavities with semi-annular partitions...

A healthy 38-year-old woman developed sudden unilateral vision loss due to retrobulbar optic neuritis in the wake of varicella-zoster virus infection. She had no further central nervous system (CNS) lesions. Antinuclear antibodies (ANA) and anti-aquaporin 4 antibodies were found, consistent with neuromyelitis optica (NMO). Later, serial MRIs showed dynamic short-segment and long-segment myelitis lesions, ANA titre increased and additional autoantibodies were found including anti-dsDNA, anti-chromatin/nucleosome and antiphospholipid antibodies...

We collected serum-cerebrospinal fluid (CSF)-paired samples during the acute phase of clinical episodes in MS and NMO patients, together with paired samples from non-MS/NMO patients, to compare the quotients of proteins and electrolytes among them. In NMO, the quotient of chloride was significantly higher in the acute phase of optic neuritis and brain lesions, but it was significantly lower in the acute phase of myelitis. Such findings were not observed in MS or in non-MS/NMO cases. With the coexistence of serum anti-AQP4-Ab, chloride imbalance between serum and CSF could be associated with the clinical episodes in NMO...

Background Myelin oligodendrocyte glycoprotein (MOG) is located on the surface of oligodendrocytes and myelin in the central nervous system. MOG-IgG is associated with acute disseminated encephalomyelitis (ADEM), relapsing and bilateral optic neuritis (NNO), and transverse myelitis (TM) in both paediatric and adult patients. The combination of NNO and TM or other inflammatory brain lesions is a typical feature of neuromyelitis optica spectrum disorders (NMO-SD) which are associated with specific pathogenic autoantibodies against the water channel aquaporin-4 (AQP4-IgG)...

Neuromyelitis optica (NMO) is clinically characterized by severe optic neuritis and transverse myelitis, but recent studies with anti-aquaporin-4-antibody specific to NMO have revealed that the clinical spectrum is wider than previously thought. International consensus diagnostic criteria propose NMO spectrum disorders (NMOSD) as the term to define the entire spectrum including typical NMO, optic neuritis, acute myelitis, brain syndrome, and their combinations. NMOSD is now divided into anti-aquaporin-4-antibody-seropositive NMOSD and -seronegative NMOSD (or unknown serostatus)...

Neuromyelitis optica spectrum disorder (NMO-SD) is an autoimmune inflammatory disorder associated with the anti-aquaporin-4 (AQP4) antibody. Over 90% of NMO-SD patients have poor prognosis, and pregnancy is a disease-worsening factor. The authors report the findings in a case of NMO-SD that recovered spontaneously during pregnancy. A 28-years-old woman developed optic neuritis (ON) of the right eye in the 14th week of pregnancy. Her best-correlated visual acuity (BCVA) was 0.02 OD, the critical flicker frequency (CFF) was not measurable, and the mean deviation (MD) of the Humphrey perimetry 30-2 was -42 dB...

Coexisting myasthenia gravis and neuromyelitis optica spectrum disorder was reported as a rare association, with only 26 reported cases in the literature. The authors report the case of a middle-aged Chinese woman with bilateral recurrent optic neuritis and seropositive ocular myasthenia gravis who was subsequently diagnosed with neuromyelitis optica spectrum. She was tested seropositive for the neuromyelitis optica immunoglobulin G (NMO-IgG) and had elevated antinuclear antibody titres, but workup for other autoimmune disorders were negative...

Platelet-Endothelial-Cell-Adhesion-Molecule-1 (PECAM-1) and Human-Vascular-CAM-1 (VCAM-1) are adhesion molecules involved in leukocyte-endothelial interaction. In our study serum levels of sPECAM-1 and sVCAM-1 were measured (ELISA) in twenty-nine patients during their first monosymptomatic optic neuritis (ON) episode. Anti-aquaporin-4-antibodies (AQP4-IgG) were detected with the cell-based assay. Patients were followed for seven years, during which 16/24 AQP4-IgG (-) patients developed MS and 2/5 AQP4-IgG (+) patients developed NMO...

BACKGROUND: Individual attacks of neuromyelitis optica (NMO) are generally severe enough to cause disability even after the onset attack. We aimed to elucidate the clinical characteristics of disabling attacks at the onset of NMO. METHODS: We investigated the clinical characteristics at onset and at first relapse in patients with NMO or NMO spectrum disorder with seropositive for the anti-aquaporin-4 antibody. A disabling attack at onset (DAO) was defined as an onset attack in which, at best recovery (allowing up to one year), patients were unable to walk without assistance or were left functionally blind in at least one affected eye...

Detection of IgG anti-Aquaporin-4 (AQP4) in serum of patients with Neuromyelitis optica syndrome disorders (NMOSD) has improved diagnosis of these processes and differentiation from Multiple sclerosis (MS). Recent findings also claim that a subgroup of patients with NMOSD, serum negative for IgG-anti-AQP4, present antibodies anti-AQP1 instead. Explore the presence of IgG-anti-AQP1 using a previously developed cell-based assay (CBA) highly sensitive to IgG-anti-AQP4. Serum of 205 patients diagnosed as NMOSD (8), multiple sclerosis (94), optic neuritis (39), idiopathic myelitis (29), other idiopathic demyelinating disorders of the central nervous system (9), other neurological diseases (18) and healthy controls (8), were used in a CBA over fixed HEK cells transfected with hAQP1-EGFP or hM23-AQP4-EGFP, treated with Triton X-100 and untreated...

A 10-year-old boy developed bilateral optic neuritis and myelitis after a suspected viral infection and appendicitis. Magnetic resonance imaging (MRI) showed multiple lesions in both optic nerves, the optic chiasm, and the spinal cord. Several small lesions were also observed in the cerebellum and cerebral white matter. The serum tested negative for anti-aquaporin (AQP)-4 antibody and positive for anti-myelin oligodendrocyte glycoprotein (MOG) antibody. The diagnosis was neuromyelitis optica spectrum disorder (NMOSD)...

The discovery of a highly specific biomarker of neuromyelitis optica (NMO)-the anti-aquaporin-4 (AQP4) antibody-has opened new paths to understanding disease pathogenesis and afforded a way to confirm the diagnosis in clinical practice. An important consequence of the discovery is the broadening of the spectrum of syndromes seen in the context of AQP4 autoimmunity. These syndromes have been subsumed under the rubric of NMO spectrum disorder (NMOSD). The current classification recognizes not only optic neuritis and myelitis as core syndromes of NMOSD but also cerebral, diencephalic, brainstem, and area postrema syndromes...
