Neuromyelitis optica (NMO) is an autoimmune demyelinating disease of the central nervous system (CNS) caused by autoantibodies (NMO-IgG) against the water channel aquaporin-4 (AQP4). Though AQP4 is also expressed outside the CNS, for example in skeletal muscle, patients with NMO generally do not show clinical/diagnostic evidence of skeletal muscle damage. Here, we have evaluated whether AQP4 supramolecular organization is at the basis of the different tissue susceptibility. Using immunofluorescence we found that while the sera of our cohort of patients with NMO gave typical perivascular staining in the CNS, they were largely negative in the skeletal muscle...

Intramedullary spinal lesions present a wide differential diagnosis including infectious, inflammatory, traumatic, ischemic, benign, or malignant neoplastic etiologies. Using knowledge of anatomy and physiology within the spinal cord, many similar appearing entities can be parsed into a prioritized differential. The purpose of this article is to review anatomy and pathophysiology of the spinal cord, with subsequent discussion of how this knowledge can be used to differentiate several similar appearing intramedullary pathologic processes...

Introduction There is paucity of reports on subtypes of Guillain-Barré syndrome (GBS) in children. We compared clinical and laboratory findings of acute inflammatory demyelinating poly-radiculo-neuropathy (AIDP) and acute motor axonal neuropathy (AMAN). Methods 140 children with GBS were included. Based on nerve conduction study (NCS), patients were sub-classified as AIDP, AMAN, acute motor sensory axonal neuropathy (AMSAN), and equivocal. Results Clinically 72.1% of patients had pure motor, 24.3% motor-sensory and 3...

INTRODUCTION: Documentation of peripheral nerve demyelination is an important part of the CIDP diagnostic process. METHODS: We performed a retrospective analysis of patients referred with a diagnosis of CIDP who were found to have a different condition. Electrodiagnostic study data and interpretations performed at the time of the initial diagnosis were compared to those obtained during the re-evaluation. RESULTS: Thirty-nine of 86 patients were found to not have CIDP...

Neuroaxonal pathology is a main determinant of disease progression in multiple sclerosis; however, its underlying pathophysiological mechanisms, including its link to inflammatory demyelination and temporal occurrence in the disease course are still unknown. We used ultra-high field (7 T), ultra-high gradient strength diffusion and T1/T2-weighted myelin-sensitive magnetic resonance imaging to characterize microstructural changes in myelin and neuroaxonal integrity in the cortex and white matter in early stage multiple sclerosis, their distribution in lesional and normal-appearing tissue, and their correlations with neurological disability...

The critically endangered population of Far Eastern leopards (Panthera pardus orientalis) may number as few as 60 individuals and is at risk from stochastic processes such as infectious disease. During May 2015, a case of canine distemper virus (CDV) was diagnosed in a wild leopard exhibiting severe neurologic disease in the Russian territory of Primorskii Krai. Amplified sequences of the CDV hemagglutinin gene and phosphoprotein gene aligned within the Arctic-like clade of CDV, which includes viruses from elsewhere in Russia, China, Europe, and North America...

BACKGROUND: Multiple sclerosis (MS) diagnostic criteria have changed since the ORACLE-MS study was conducted; 223 of 616 patients (36.2%) would have met the diagnosis of MS vs clinically isolated syndrome (CIS) using the newer criteria. OBJECTIVE: The objective of this paper is to assess the effect of cladribine tablets in patients with a first clinical demyelinating attack fulfilling newer criteria (McDonald 2010) for MS vs CIS. METHODS: A post hoc analysis for subgroups of patients retrospectively classified as fulfilling or not fulfilling newer criteria at the first clinical demyelinating attack was conducted...

Multiple sclerosis (MS) is an inflammatory demyelinating disease in which cytokines produced by immune cells that infiltrate the brain and spinal cord play a central role. We show here that the IL-12p35, the alpha subunit of IL-12 or IL-35 cytokine, might be an effective biologic for suppressing neuroinflammatory responses and ameliorating the pathology of experimental autoimmune encephalomyelitis (EAE), the mouse model of human MS. We further show that IL-12p35 conferred protection from neuropathy by inhibiting the expansion of pathogenic Th17 and Th1 cells and inhibiting trafficking of inflammatory cells into the brain and spinal cord...

Lysophosphatidic acid (LPA) is a pleiotropic signaling lipid that acts as ligand for at least six specific G-protein coupled receptors. Schwann cells (SC) are known to mainly express the LPA1 receptor subtype. An emerging body of evidence has linked LPA with injury-induced peripheral nerve demyelination as well as neuropathic pain. However, the molecular mechanisms underlying its demyelinating effect have not been conclusively elucidated. We aimed to decipher the demyelinating effect in vitro as well as in vivo by studying markers of SC differentiation and dedifferentiation: Myelinated dorsal root ganglia (DRG) cultures were treated either with LPA, LPA plus AM095 (LPA1 antagonist) or vehicle...

INTRODUCTION: Recent studies with SD OCT had shown early axonal damage to the macular ganglion cell complex (which consists of the three innermost layers of the retina: Inner Plexiform Layer [IPL], Ganglion Cell Layer [GCL], Retinal Nerve Fibre layer [RNFL]) in optic nerve pathology. Retrobulbar optic neuritis (RBON), occurring frequently in demyelinating diseases, leads to atrophy of the optic nerve fibers at the level of the ganglion cell axons, previously described in the literature...

Decreased health-related quality of life (HRQOL) in pediatric patients with multiple sclerosis is established, but little research has examined HRQOL in the broader pediatric demyelinating disease population, and predictors of reduced HRQOL are largely unexplored. We sought to (1) compare generic HRQOL and fatigue of pediatric patients with relapsing (i.e., multiple sclerosis and neuromyelitis optica) versus monophasic demyelinating diseases (i.e., acute disseminated encephalomyelitis, optic neuritis, transverse myelitis, clinically isolated syndrome) and (2) examine the extent to which disability, relapsing disease, and fatigue predict HRQOL...

RATIONALE: Central nervous system (CNS) involvement of graft versus host disease (GvHD) is a rare cause of CNS disorders after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Chronic CNS GvHD symptoms are heterogeneous and include cerebrovascular manifestations, demyelinating disease and immune-mediated encephalitis. CNS-Acute GvHD is not formally defined in literature. PATIENTS CONCERNS AND DIAGNOSES: We report 7 cases of CNS-GvHD among which two had histological-proven disease...

BACKGROUND: Even with abundant evidence for osmotic demyelination in patients with hyponatremia, the risk factors for overcorrection have not been fully investigated. Therefore the purpose of this study is to clarify the risks for overcorrection during the treatment of chronic profound hyponatremia. METHODS: This is a single-center retrospective observational study. We enrolled 56 adult patients with a serum sodium (SNa) concentration of ≤125 mEq/L who were treated in an intensive care unit by nephrologists using a locally developed, fixed treatment algorithm between February 2012 and April 2014...

Sonic hedgehog (Shh) regulates a wave of oligodendrocyte production for extensive myelination during postnatal development. During this postnatal period of oligodendrogenesis, we fate-labeled cells exhibiting active Shh signaling to examine their contribution to the regenerative response during remyelination. Bitransgenic mouse lines were generated for induced genetic fate-labeling of cells actively transcribing Shh or Gli1. Gli1 transcription is an effective readout for canonical Shh signaling. Shh(CreERT2) mice and Gli1(CreERT2) mice were crossed to either R26(tdTomato) mice to label cells with red fluorescence, or, R26(IAP) mice to label membranes with alkaline phosphatase...

It has been proposed that susceptibility-weighted imaging is a sensitive magnetic resonance imaging (MRI) technique for identifying white matter (WM) pathologic changes involving demyelination and iron accumulation. We identified the tree silhouette-like configuration with a paramagnetic phase shift in the frontal subcortical WM lesions of 4 patients with adult-onset leukoencephalopathy with axonal spheroids and pigmented glia who underwent 3T MRI. According to our postmortem 7T MRI and histologic correlation study to investigate the origin of the susceptibility-related phase contrast, changes in the subcortical WM architecture and central WM loss with the relative preservation of iron-rich U-fibers may contribute to the paramagnetic susceptibility...

This article focuses on the unconventional treatments used in chronic inflammatory demyelinating polyneuropathy (CIDP). First line, evidence-based treatments for CIDP include corticosteroids, immunoglobulins and plasma exchanges. Several unproven treatments are however given in treatment-refractory disease or to reduce requirements in validated therapies for reasons of side effects/practical delivery/cost. Despite methodological issues, IFN-α, azathioprine and methotrexate have not been shown to be useful in randomized controlled trials...

Imaging markers that are reliable, reproducible and sensitive to neurodegenerative changes in progressive multiple sclerosis (MS) can enhance the development of new medications with a neuroprotective mode-of-action. Accordingly, in recent years, a considerable number of imaging biomarkers have been included in phase 2 and 3 clinical trials in primary and secondary progressive MS. Brain lesion count and volume are markers of inflammation and demyelination and are important outcomes even in progressive MS trials...

Highly effective anti-inflammatory therapies have so far been developed for patients with relapsing/remitting multiple sclerosis, which also show some benefits in the early progressive stage of the disease. However, treatment options for patients, who have entered the progressive phase, are still limited. Disease starts as an inflammatory process, which induces focal demyelinating lesions in the gray and white matter. This stage of the disease dominates in the relapsing phase, extends into the early stages of progressive disease, and can be targeted by current anti-inflammatory treatments...
