BACKGROUND The diagnostic accuracy of cerebrospinal fluid oligoclonal bands (CSF-OCB) detected by isoelectric focusing (IEF) in patients with multiple sclerosis (MS) was evaluated in our study. METHODS Three hundred and twenty-one patients with MS and other central nervous system (CNS) immune mediated disorders were assessed (CIMD). Cerebrospinal fluid and matched serum samples were examined ...

Sixteen children with definite multiple sclerosis (MS; aged 6-17 years, mean 11.4 +/- 2.7; 8 boys, 8 girls) were reviewed. Cerebellar symptoms and signs were frequent at initial presentation. Among laboratory studies, the cerebrospinal fluid (CSF) IgG index or oligoclonal bands were informative in 75%, evoked potentials in 70%, electroencephalography (EEG) in 83%, magnetic resonance imaging in ...

The natural course of disease in multiple sclerosis varies. Multiple sclerosis that is clinically apparent but causes minimal disability over time has been labeled benign multiple sclerosis. The ability to predict the subsequent clinical course of multiple sclerosis on the basis of clinical and other supportive data at presentation would be invaluable. In this article we report our findings bas...

The demonstration of intrathecal IgG synthesis has been used as an important laboratory parameter to support the diagnosis of multiple sclerosis (MS). The Committee for European Concerted Action for Multiple Sclerosis has recommended a protocol for the assessment of intrathecal IgG synthesis. We applied this methodology to determine the cerebrospinal (CSF) profile of 128 Brazilian patients with...

INTRODUCTION In this study authors have analyzed the correlation between the IgG immunoglobulins in cerebrospinal fluid and the findings of oligoclonal bands on gel. Immunoglobulin IgG in cerebrospinal fluid (CSF) can be detected in neurological diseasses (infections and inflammatory neurological diseases and in demyelinating diseases, like multiple sclerosis (MS)). Quantitative IgG in CSF can ...

In this study free kappa light chains in cerebrospinal fluid (CSF) were determined both by an affinity mediated capillary blotting technique after isoelectric focusing (IEF) in agarose gel and by a quantitative enzyme linked immunosorbent assay (ELISA). The free kappa results were compared with the IgG findings in 4 neurological patient groups with a distinct CSF IgG pattern: (1) CSF without ol...

BACKGROUND Intrathecal immunoglobulin synthesis is observed in several inflammatory disorders of the central nervous system, but its detection by current laboratory tests is either tedious or relatively insensitive. We assessed the diagnostic accuracy of an assay for kappa free light chains (kappaFLC) in cerebrospinal fluid (CSF) and serum, and compared it with traditional tests for intrathecal...
