A 73-year-old man presented with three episodes of dysphasia and disinhibited behaviour, a single seizure and transient ischaemic attack-like events characterised by right arm and/or leg weakness. These episodes were separated by month-long asymptomatic intervals. Medical history included rheumatoid arthritis, which was clinically quiescent on leflunomide.Repeated cerebrospinal fluid examination showed a persistent lymphocytosis with mildly reduced glucose and elevated protein; oligoclonal bands and viral PCR were negative...

Primary CNS (central nervous system) lymphoma is a rare condition with the incidence of less than 1% of all non-Hodgkin lymphomas (NHLs) and approximately 2% of all primary brain tumours. Diagnosis can be challenging and necessitates brain biopsy for definitive diagnosis. A 41-year male presented with history of impaired cognition, facial asymmetry, visual impairment and left sided body weakness. MRI brain demonstrated multiple enhancing lesions with one larger lesion in right basal ganglia with surrounding oedema and mass effect...

OBJECTIVE: Ictal activity itself can cause pathological cerebrospinal fluid (CSF) findings. However, data regarding pathological CSF findings caused by SE itself to date remain scarce. We here evaluated the frequency and specificity of pathological CSF findings in non-infectious SE. METHODS: We performed a retrospective analysis of CSF samples in adult patients with episodes of non-infectious SE, who had been admitted to the Department of Neurology, University Hospital of Cologne...

The 2010 McDonald criteria for the diagnosis of multiple sclerosis are widely used in research and clinical practice. Scientific advances in the past 7 years suggest that they might no longer provide the most up-to-date guidance for clinicians and researchers. The International Panel on Diagnosis of Multiple Sclerosis reviewed the 2010 McDonald criteria and recommended revisions. The 2017 McDonald criteria continue to apply primarily to patients experiencing a typical clinically isolated syndrome, define what is needed to fulfil dissemination in time and space of lesions in the CNS, and stress the need for no better explanation for the presentation...

Viliuisk encephalomyelitis (VE) is a neurodegenerative disease that afflicts aboriginal people of Yakutia in Siberia with unknown etiology. Oligoclonal IgG bands (OCBs) were discovered in the VE patients (Green et al., 2003). In this study we analysed the association of OCBs with clinical symptoms in 58 VE patients. Positive oligoclonal IgG are associated with a shorter duration of disease (p=0.002), older age of onset (p=0.023) and high frequency of main neurological VE symptoms such as dementia, frontal dysbasia, bulbar disorders, muscle atrophy and centrally caused pelvic disorders...

Background: IgG concentrations in cerebrospinal fluid generally range from 20 to 45 mg/L. In multiple sclerosis immune reactions lead to intrathecal synthesis of specific IgGs that can be detected in biological fluid samples both quantitatively and qualitatively by isoelectric focusing of supplementary oligoclonal IgG bands. Method: A simple tool, using the MATLAB application, to facilitate and improve isoelectric focusing profile analysis is presented and evaluated in terms of its sensitivity, repeatability and reproducibility...

The paraneoplastic cerebellar syndrome presents as severe neuroimmunological disease associated with malignancies. Antibodies against antigens expressed by tumor cells cross-react with proteins of cerebellar Purkinje cells leading to neuroinflammation and neuronal loss. These antineuronal antibodies are preferentially investigated by serological analyses while examination of the cerebrospinal fluid is only performed infrequently. We retrospectively investigated twelve patients with antineuronal antibodies against Purkinje cells with a special focus on cerebrospinal fluid...

Only few reports exist regarding the coexistence of multiple sclerosis (MS) and autoimmune myopathies. We describe the case of a man with a long history of undiagnosed left lower limb motor impairment who was hospitalized for subacute onset of a myopathic syndrome. In addition, neurological examination revealed sensory impairment and pyramidal signs in the left limbs. Muscle biopsy revealed a necrotizing myopathy and serum anti-signal recognition particle (SRP) antibodies were found. Brain and spinal cord MRI displayed several non-enhancing demyelinating lesions, and CSF-restricted oligoclonal bands were detected...

Although oligoclonal bands in the cerebrospinal fluid have been a hallmark of multiple sclerosis diagnosis for over three decades, the role of antibody-secreting cells in multiple sclerosis remains unclear. T and B cells are critical for multiple sclerosis pathogenesis, but increasing evidence suggests that plasma cells also contribute, through secretion of autoantibodies. Long-lived plasma cells are known to drive various chronic inflammatory conditions as e.g. systemic lupus erythematosus, however, to what extent they are present in autoimmune central nervous system inflammation has not yet been investigated...

BACKGROUND: The emergence of oligoclonal bands, proteins differing from those originally identified at diagnosis, has been reported in multiple myeloma patients after high-dose chemotherapy followed by autologous stem cell transplantation and after successful conventional chemotherapy. The clinical relevance of oligoclonal bands remains unclear, but their emergence has been associated with better prognosis. The aim of the present study was to determine the prevalence, clinical characteristics and prognostic impact of the presence of oligoclonal bands in multiple myeloma patients...

Nonimaging biomarkers can be applied in differential diagnosis, evaluation of disease progression and therapy monitoring of multiple sclerosis (MS). Presence of oligoclonal IgG bands in cerebrospinal fluid is a diagnostic element and a negative predictor of MS evolution. AQP4 antibodies are pathogenic and diagnostic for neuromyelitis optica spectrum disorder. Antibodies to myelin oligodendrocyte glycoprotein develop in about 50% of predominantly pediatric patients with acute disseminated encephalomyelitis, but their possible role in pathogenesis is unknown...

BACKGROUND: Oligoclonal bands of IgG (OB) are proposed as an early prognostic factor of the disease. Growing attention is directed towards brain volume evaluation as a possible marker of the severity of MS. Previous studies found that MS patients lacking OB have less brain atrophy. AIM: to evaluate a possible relationship between OB and cerebral volume in a cohort of early MS patients. METHODS: Inclusion criteria were: diagnosis of relapsing-remitting MS; CSF analysis and MRI acquired simultaneously and within 12 months from clinical onset...

The radiological spectrum of neuromyelitis optica has become broader since the detection of aquaporin4 antibodies. We report a case of neuromyelitis optica patient with pseudotumoral encephalic lesion. A 66 year-old woman presented with sudden left lateral homonymous hemianopsia. A brain MRI showed an isolated and extensive right temporo-parieto-occipital lesion, involving periventricular white matter and the corpus callosum, with strong enhancement on post-gadolinium T1 weighted images, highly suggestive of lymphoma...

INTRODUCTION: Intrathecal immunoglobulin G (IgG) and oligoclonal bands (OCBs) are the most consistent and characteristic features of Multiple Sclerosis (MS). OCBs in MS are considered products of clonally expanded B cells in the cerebrospinal fluid (CSF), representing the sum of contributions from B cells in the brain. However, large amounts of IgG can be eluted from MS plaques in which lymphocytes are absent, and there is no correlation between levels of plaque-associated IgG and the presence of lymphocytes...

A hexanucleotide repeat expansion in the C9orf72 gene is associated with amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration. It has been described before four patients with multiple sclerosis (MS) and C9orf72-ALS. However, C9orf72 positivity is not associated with increased risk of MS. Inflammatory pathways related to NF-κB have been linked to ALS and MS, and appear to be important in C9orf72-ALS patients. A 42-year-old woman presented with progressive bulbar symptoms for 9 months. Neurological examination disclosed spastic dysarthria, atrophic tongue with fasciculations, brisk jaw and limb tendon reflexes, and bilateral Hoffman sign...

This document presents the guidelines for the cerebrospinal fluid (CSF) analysis and the determination of oligoclonal bands (OCBs) as pivotal tests in neuroinflammatory pathologies of the central nervous system. The guidelines have been developed following a consensus process built on questionnaire-based surveys, internet contacts, and discussions at workshops of the sponsoring Italian Association of Neuroimmunology (AINI) congresses. Essential clinical information on the pathologies in which the CSF analysis is indicated, and, particularly, on those characterized by the presence of OCBs in the intrathecal compartment, indications and limits of CSF analysis and OCB determination, instructions for result interpretation, and agreed laboratory protocols (Appendix) are reported for the communicative community of neurologists and clinical pathologists...
