AIM: Our objectives were to evaluate the utility of measuring myelin oligodendrocyte glycoprotein (MOG) and aquaporin-4 (AQP4) antibodies (Ab) in clinical practice and describe their associated neurological phenotypes in children. METHOD: Between 2012 and 2017, 371 children with suspected acquired demyelinating syndromes (ADS) seen in three tertiary centres were tested for MOG-Ab and AQP4-Ab. Medical notes were retrospectively reviewed, and clinical and demographic data compiled...

PURPOSE OF REVIEW: Neuromyelitis optica spectrum disorders (NMOSD) are severe inflammatory diseases of the central nervous system (CNS), with the presence of aquaporin 4 (AQP4)-specific serum antibodies in the vast majority of patients, and with the presence of myelin oligodendrocyte glycoprotein (MOG)-specific antibodies in approximately 40% of all AQP4-antibody negative NMOSD patients. Despite differences in antigen recognition, the preferred sites of lesions are similar in both groups of patients: They localize to the spinal cord and to the anterior visual pathway including retina, optic nerves, chiasm, and optic tracts, and - to lesser extent - also to certain predilection sites in the brain...

Neuromyelitis optica spectrum disorders (NMOSDs) are a set of demyelinating disorders that primarily target the optic nerves and the spinal cord. Previously thought to be a subset of multiple sclerosis (MS), now is recognized as a distinct entity. We present a 59-year-old female patient who was admitted for acute upper and lower extremity weakness. The patient had woken up from sleep with sudden onset of weakness. Patient was initially diagnosed with a right hemispheric stroke; however, magnetic resonance imaging of the cervical spine later performed showed abnormal enhancement from C2-C4, representing transverse myelitis...

Antibodies against the myelin oligodendrocyte glycoprotein (MOG-Ab) can be detected in various pediatric acquired demyelinating syndromes (ADS). Here, we analyze the spectrum of neuroradiologic findings in children with MOG-Ab and a first demyelinating event. The cerebral and spinal MRI of 69 children with different ADS was assessed in regard to the distribution and characteristics of lesions. Children with acute disseminated encephalomyelitis (n = 36) or neuromyelitis optica spectrum disorder (n = 5) presented an imaging pattern characterized predominantly by poorly demarcated lesions with a wide supra- and infratentorial distribution...

Neuromyelitis optica, also known as Devic's disease, is an autoimmune disorder that leads to the inflammation and demyelination of nerves. Devic's disease primarily affects the optic nerve and spinal cord, but can lead to a significant loss of function throughout the body if not treated with steroid therapy or plasmapheresis. We recently saw a 62-year-old patient who received plasmapheresis for Devic's disease through a PTFE arteriovenous graft in her left arm. Her graft clotted without warning, and percutaneous thrombolysis was not successful...

Aquaporin-4 immunoglobulin G -positive neuromyelitis optica spectrum disorder (NMOSD-AQP4) is an inflammatory disease of the central nervous system that predominantly affects the optic nerves and spinal cord. Rituximab (RTX)-a monoclonal antibody to CD20 in B cells-is effective in the treatment of NMOSD. However, interstitial lung disease (ILD) is a very rare yet potentially fatal complication of RTX treatment. Here, we detail the first reported case of RTX-induced ILD in a patient with NMOSD-AQP4. ILD should be suspected in patients with NMOSD undergoing RTX treatment who present with dyspnea and/or cough without any signs or symptoms of infection...

Neuromyelitis optica is a neurotropic autoimmune inflammatory disease of the central nervous system traditionally thought to exclusively involve the optic nerves and spinal cord. With the discovery of the disease-specific aquaporin-4 antibody and the increasing recognition of clinical and characteristic imaging patterns of brain involvement in what is now termed neuromyelitis optica spectrum disorder (NMOSD), magnetic resonance imaging now plays a greater role in diagnosis of NMOSD based on the 2015 consensus criteria and in distinguishing it from other inflammatory disorders, particularly multiple sclerosis...

Neuromyelitis optica is an inflammatory, demyelinating disease of the central nervous system that is characterized by severe relapsing attacks of optic neuritis and transverse myelitis. The current case describes a 29-year-old man with intractable epilepsy and diplegic spastic cerebral palsy who was given the diagnosis of neuromyelitis optica spectrum disorder after presenting with weakness, incontinence, and decreased visual acuity. His symptoms recurred 21 months after initial presentation. Magnetic resonance imaging of his spine revealed arachnoid cysts with regional mass effects...

AIM: To determine the thickness of the retinal ganglion cell-inner plexiform layer (GCIPL) and the retinal nerve fiber layer (RNFL) in patients with neuromyelitis optica (NMO). METHODS: We conducted a cross-sectional study that included 30 NMO patients with a total of 60 eyes. Based on the presence or absence of optic neuritis (ON), subjects were divided into either the NMO-ON group (30 eyes) or the NMO-ON contra group (10 eyes). A detailed ophthalmologic examination was performed for each group; subsequently, the GCIPL and the RNFL were measured using high-definition optical coherence tomography (OCT)...

BACKGROUND: The 2015 International Panel for neuromyelitis optica (NMO) spectrum disorders (NMOSD) diagnosis (IPND) criteria was recently proposed. However, because there are no studies evaluating application of the IPND criteria in Latin American populations, we aimed to assess whether these new criteria improve the diagnostic rate and reduce the time taken to make the diagnosis in a cohort of Latin American patients. METHODS: We reviewed medical records and applied both the 2006 and 2015 diagnostic criteria to all patients seen in four centers in Argentina, Brazil and Venezuela...

Neuromyelitis optica (NMO) and Neuromyelitis optica spectrum disorders (NMOSD) are a group of autoimmune conditions characterized by inflammatory involvement of the optic nerve, spinal cord and central nervous system. Novel evidence showed a key role of autoantibodies against aquaporin-4 immunoglobulin G (AQP4 IgG) in the pathogenesis of NMOSD and, recently, new classification and diagnostic criteria have been adopted to facilitate an earlier identification and improve the management of these conditions. Diagnosis of NMOSD is currently based on clinical, neuroimaging and laboratory features...

BACKGROUND Neuromyelitis optica (NMO) is a rare demyelinating disease of the central nervous system; NMO predominantly affects the spinal cord and optic nerves. The diagnosis is based on history, clinical presentation, seropositive NMO-IgG antibody, and notably, exclusion of other diseases. Despite the absence of definitive therapeutic strategies for NMO, methylprednisolone pulse therapy and plasma exchange are used for acute phase treatment, while immunosuppressive agent(s) are recommended to prevent relapses and improve prognosis...

Neuromyelitis optic spectrum disorders are demyelinating conditions that are typically idiopathic, though various case reports have demonstrated an association with malignancy. We present the case of a 64year old woman with NMOSD in the setting of small cell lung cancer. She had longitudinally extensive transverse myelitis and left eye optic neuritis; aquaporin-4 antibodies were elevated. Biopsy of mediastinal adenopathy was positive for SCLC. Malignancy should be considered in any patient with an atypical presentation of NMOSD, or who does not respond to traditional therapies...

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...
