The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a potential cause of hyponatremia of the central nervous system (CNS). Although SIADH has been reported to be associated with many other central nervous disorders, its association with neuromyelitis optica (NMO) or NMO spectrum disorders are rare. NMO is a demyelinating disorder characterized by optic neuritis and transverse myelitis. Aquaporin-4 (AQP4), which is the target antigen for a NMO autoantibody, is the predominant CNS water channel...

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)...

BACKGROUND AND PURPOSE: Neuromyelitis optica spectrum disorders are inflammatory demyelinating disorders with optic neuritis and/or longitudinally extensive transverse myelitis episodes. We now know that neuromyelitis optica spectrum disorders are associated with antibodies to aquaporin-4, which are highly concentrated on astrocytic end-feet at the blood-brain barrier. Immune-mediated disruption of the blood-brain barrier may manifest as contrast enhancement on brain MR imaging. We aimed to delineate the extent and frequency of contrast enhancement on brain MR imaging within 1 month of optic neuritis and/or longitudinally extensive transverse myelitis attacks and to correlate contrast enhancement with outcome measures...

REVIEW
Alina Masters-Israilov, Matthew S Robbins
PURPOSE OF REVIEW: Neuromyelitis optica (NMO) classically features a clinical presentation that includes longitudinally extensive transverse myelitis and optic neuritis. However, many other pathognomonic phenomena have more recently been described in patients diagnosed with NMO, including intractable hiccups, vomiting, and painful tonic spasms, but less has been reported regarding the relationship between NMO and headache. Though headache is well established as both a symptom and comorbidity of multiple sclerosis (MS), it has been much less described thus far in the NMO literature and warrants more careful evaluation...

Therapeutic plasma exchange (TPE) is a procedure that reduces circulating autoantibodies of the patients. TPE is commonly used in neurological disorders where autoimmunity plays a major role. We report our experience with regard to the indications, adverse events and outcomes of plasma exchange in neurological disorders. Sixty-three patients were included to this retrospective study. Median age was 48 years (range 1-85), there was a predominance of males. Neurological indications included Guillain-Barrè syndrome (n = 22), myasthenia gravis (n = 21), chronic inflammatory demyelinating polyneuropathy (n = 7), polymyositis (n = 3), multifocal motor neuropathy (n = 2), acute disseminated encephalomyelitis (n = 2), neuromyelitis optica (n = 2), multiple sclerosis (n = 2), limbic encephalitis (n = 1) and transverse myelitis (n = 1)...

BACKGROUND: Longitudinally extensive transverse myelitis (LETM) is a frequent manifestation of neuromyelitis optica spectrum disorder (NMOSD). However, it can also occur in other immune-mediated diseases of the central nervous system (CNS). Positive aquoporin-4 antibodies (AQP4-ab) predict higher relapse rate after LETM. OBJECTIVE: To assess clinical and brain/spinal cord magnetic resonance imaging (MRI) features of LETM immune-mediated at onset and to compare AQP4-ab negative (N-LETM) with AQP4-ab positive (P-LETM) patients...

Vomiting and hiccups can be the manifestations of numerous systemic and neurological illnesses. Intractable nausea, vomiting and hiccups (INH) are reported as possible initial manifestations of neuromyelitis optica (NMO), but not correctly identified. Awareness of these atypical presentations is conducive to NMO early diagnosis and proper treatment to prevent further disability. In this paper, 12 NMO were reported, whose intractable vomiting and hiccups were the sole manifestations of the first attack and other attacks involving spinal cord and optic nerves developed later...

Central nervous system (CNS) inflammatory demyelinating diseases (IDDs) are a group of disorders with different aetiologies, characterized by inflammatory lesions. These disorders include multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and idiopathic transverse myelitis (ITM). Differential diagnosis of the CNS IDDs still remains challenging due to frequent overlap of clinical and radiological manifestation, leading to increased demands for new biomarker discovery. Since cerebrospinal fluid (CSF) metabolites may reflect the status of CNS tissues and provide an interfacial linkage between blood and CNS tissues, we explored multi-component biomarker for different IDDs from CSF samples using gas chromatography mass spectrometry-based metabolite profiling coupled to multiplex bioinformatics approach...
