BACKGROUND: PET ligands targeting the translocator protein (TSPO) represent promising tools to visualise neuroinflammation. Here, we analysed parameters obtained in dynamic and static PET images using the novel TSPO ligand [(18)F]GE-180 in patients with relapsing remitting multiple sclerosis (RRMS) and an approach for semi-quantitative assessment of this disease in clinical routine. Seventeen dynamic [(18)F]GE-180 PET scans of RRMS patients were evaluated (90 min). A pseudo-reference region (PRR) was defined after identification of the least disease-affected brain area by voxel-based comparison with six healthy controls (HC) and upon exclusion of voxels suspected of being affected in static 60-90 min p...

BACKGROUND: Data on the incidence of multiple sclerosis (MS) on the national level is scarce. We aimed to estimate the incidence of MS in Germany and to compare different MS case definitions based on claims data. METHODS: We conducted a cohort study with the German Pharmacoepidemiological Research Database in 2012 and calculated age- and gender-standardized incidence rates (sIRs) for 3 case definitions. In addition, the effect of stepwise reduction of the look-back period without MS diagnosis on the incidence rate was evaluated...

The last several decades have witnessed considerable progress in our understanding of the pathogenesis, refining diagnostic criteria, and identifying therapies of value for modifying the course of relapsing forms of multiple sclerosis. While the pace of progress has lagged for those with progressive phase disease, this now seems to be changing. This review considers those characteristics of patients with primary progressive multiple sclerosis that may contribute to phase 3 trial success and identifies some of the thorny issues that remain ahead...

Liliana Patrucco
The diagnosis of multiple sclerosis (MS) is based on neurological symptoms and signs, alongside evidence of dissemination of central nervous system (CNS) lesions in space and time. In the absence of a sensitive and specific diagnostic test, diagnostic criteria are needed for diagnosing MS. The caveat to the application of the McDonald criteria is that alternative diagnoses must be excluded. The prevalence, clinical phenotype and the differential diagnosis of MS may have variations in different populations, especially in Latin America (LATAM)...

Melinda Y Chang, Stacy L Pineles
Optic neuritis is rare in children in comparison to adults, but accounts for approximately 25% of pediatric acute demyelinating syndromes. Features of pediatric optic neuritis that differ from adults include a higher rate of bilaterality, poor visual acuity on presentation, and papillitis. Diagnostic work-up includes brain magnetic resonance imaging, lumbar puncture, and blood tests to exclude infectious and inflammatory disorders. Pediatric optic neuritis may occur following infection or vaccination, or in association with a systemic demyelinating process such as acute disseminated encephalomyelitis, neuromyelitis optica, or multiple sclerosis...

BACKGROUND: The diagnosis of multiple sclerosis (MS) is currently based solely on clinical and magnetic resonance imaging features. However, histopathological studies have revealed four different patterns of lesion pathology in patients diagnosed with MS, suggesting that MS may be a pathologically heterogeneous syndrome rather than a single disease entity. OBJECTIVE: The aim of this study was to investigate whether patients with pattern I MS differ from patients with pattern II or III MS with regard to cerebrospinal fluid (CSF) findings, especially with reference to intrathecal IgG synthesis, which is found in most patients with MS but is frequently missing in MS mimics such as aquaporin-4-IgG-positive neuromyelitis optica spectrum disorders and myelin oligodendrocyte glycoprotein-IgG-positive encephalomyelitis...

Concentrations of cell-free DNA (cfDNA) circulating in blood and its epigenetic variation, such as DNA methylation, may provide useful diagnostic or prognostic information. Long interspersed nuclear element-1 (LINE-1) constitutes approximately 20% of the human genome and its 5'UTR region is CpG rich. Due to its wide distribution, the methylation level of the 5'UTR of LINE-1 can serve as a surrogate marker of global genomic DNA methylation. The aim of the current study was to investigate whether the methylation status of LINE-1 elements in serum cell-free DNA differs between relapsing remitting multiple sclerosis (RRMS) patients and healthy control subjects (CTR)...

Multiple sclerosis (MS) is a chronic inflammatory and demyelinating disease of autoimmune originate. The main agents responsible for the MS development include exogenous, environmental, and genetic factors. MS is characterized by multifocal and temporally scattered central nervous system (CNS) damage which lead to the axonal damage. Among clinical courses of MS it can be distinguish relapsing-remitting multiple sclerosis (RRMS), secondary progressive multiple sclerosis (SPSM), primary progressive multiple sclerosis (PPMS), and progressive-relapsing multiple sclerosis (RPMS)...

INTRODUCTION: Multiple sclerosis (MS) is an inflammatory-demyelinating disease of the central nervous system (CNS). Autoimmune inflammation is common in the early stages of MS and is followed by neurodegenerative processes. The result of these changes is axon and myelin breakdown. The paraclinical examination methods are an important part of the diagnostic process. Magnetic resonance imaging of the brain and the cervical spinal cord and an examination of cerebrospinal fluid (CSF) are common paraclinical examinations...

A multiple sclerosis (MS) diagnosis often relies upon clinical presentation and qualitative analysis of standard, magnetic resonance brain images. However, the accuracy of MS diagnoses can be improved by utilizing advanced brain imaging methods. We assessed the accuracy of a new neuroimaging marker, visual-evoked cerebral metabolic rate of oxygen (veCMRO₂), in classifying MS patients and closely age- and sex-matched healthy control (HC) participants. MS patients and HCs underwent calibrated functional magnetic resonance imaging (cfMRI) during a visual stimulation task, diffusion tensor imaging, T₁- and T₂-weighted imaging, neuropsychological testing, and completed self-report questionnaires...
