BACKGROUND AND AIMS: Detection of oligoclonal IgG (o-IgG) in the cerebrospinal fluid (CSF) not found in serum is the principal laboratory test to support a diagnosis of multiple sclerosis. The aim of this study was to compare chemiluminescent and chromogenic detection of oligoclonal immunoglobulins in the cerebrospinal fluid and serum after their separation by means of isoelectric focusing followed by immunoblotting. METHODS: A set of experiments was designed to detect oligoclonal immunoglobulins by means of alkaline phosphatase BCIP/NBT substrate and chemiluminescent peroxidase substrate...

The presence of oligoclonal bands in clinically isolated syndromes is an independent risk factor for developing multiple sclerosis and has been largely excluded from the more recent multiple sclerosis diagnostic criteria. Therefore, our objective was to explore the value of oligoclonal bands in the context of the 2010 McDonald criteria, especially in patients fulfilling exclusively dissemination in space at baseline. For this purpose, we selected 566 patients from a clinically isolated syndrome inception cohort who had IgG oligoclonal bands determination and sufficient data on baseline brain MRI to assess dissemination in space and time...

OBJECTIVE: The clinical condition of multiple sclerosis (MS) patients depends not only on the course of MS but also on their lifestyle and comorbidities. This study aimed to assess the effect of selected comorbidities, lifestyle-related factors and clinical data available at the time of MS diagnosis, on the disease activity and the disability progression in patients with relapsing-remitting multiple sclerosis (RRMS). PATIENTS AND METHODS: Based on clinical relapses over a period of 12 months of observation and the results of MRI scans, 138 patients with RRMS were qualified into two groups: 'active' or 'stable' course of the disease...

BACKGROUND: Cerebrospinal fluid (CSF) used in immunoglobulin gamma (IgG) index testing and oligoclonal bands (OCBs) are common laboratory tests used in the diagnosis of multiple sclerosis. The measurement of CSF free light chains (FLC) could pose as an alternative to the labor-intensive isoelectric-focusing (IEF) gels used for OCBs. METHODS: A total of 325 residual paired CSF and serum specimens were obtained after physician-ordered OCB IEF testing. CSF kappa (cKFLC) and lambda FLC (cLFLC), albumin and total IgG were measured...

The prognostic role of cerebrospinal fluid molecular biomarkers determined in early pathogenic stages of multiple sclerosis has yet to be defined. In the present study, we aimed to investigate the prognostic value of chitinase 3 like 1 (CHI3L1), neurofilament light chain, and oligoclonal bands for conversion to clinically isolated syndrome and to multiple sclerosis in 75 patients with radiologically isolated syndrome. Cerebrospinal fluid levels of CHI3L1 and neurofilament light chain were measured by enzyme-linked immunosorbent assay...

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 12 patients with antineuronal antibodies against Purkinje cells with a special focus on cerebrospinal fluid...
