Objective: To study the significance of oligoclonal bands in neurological disorders, specifically in Multiple Sclerosis (MS). Methods: The study was designed to assess the sensitivity and specificity of the test methodology of CSF electrophoresis by performing the retrospective analysis of CSF samples sent for oligoclonal bands (OCB) oligoclonal IgG bands (OCB IgG) analysis can evaluate intrathecal synthesis. We analyzed the prevalence of OCB IgG in MS and clinically isolated syndrome (CIS), the role of OCB IgG in the MS prognosis and CIS conversion, as well as its correlation with latitude effect. From 93 articles, 32 were used according to the inclusion criteria. Th Oligoclonal Bands are the product of inflammatory activity by the immune system. In MS this kind of activity is present in the vast majority of people with MS. We see the results of this in the T2 Hyperintense lesions and in the presence of unique O-Bands found in the CSF

Oligoclonal bands are present in the CSF of approximately 90% of MS patients. A patient is considered positive for CSF oligoclonal bands if there are two or more bands in the CSF immunoglobulin region that are not present in the serum. In order to confirm local production of oligoclonal IgG in CSF, a matched serum sample is required The determination of oligoclonal bands is a useful aid in the diagnosis of multiple sclerosis, subacute sclerosing panencephalitis, and herpes simplex encephalitis. The presence of oligoclonal bands indicates an immunological response but is not diagnostic for a particular condition

Immunoglobulins in oligoclonal bands secreted by plasma cells in the CNS can contribute to worsening pathology in MS. Secreted immunoglobulin can interact with microglial Fc receptors in an antigen non-specific manner. Microglia and astrocytes may create a survival niche for long-term plasma cell survival. Plasma cells, microglia and astrocytes. Oligoclonal bands are multiple distinct bands in the γ zone of the CSF pattern that are not present in serum. These bands in the CSF pattern are produced by a limited number of immunocompetent cell clones, each producing IgG with its own specificity. More than 90% of patients with multiple sclerosis show oligoclonal banding at some time during. Oligoclonal bands are immunoglobulins that collect in a patient's blood plasma or cerebrospinal fluid (CSF). The presence of OCBs in the CSF has often been used as a diagnostic criterion in MS. Though not every person with MS has OCBs, their presence is generally associated with a younger age of onset and a poorer disease outcome

We see the results of this in the T2 Hyperintense lesions and in the presence of unique O-Bands found in the CSF. What causes the immune system to produce O-Bands is not known - that. Genetic susceptibility is a well-recognized factor in the onset of multiple sclerosis (MS). The objective of this study was to determine the frequency of oligoclonal bands (OCB) restricted to the cerebrospinal fluid, in an ethnically mixed group of MS patients in the city of São Paulo, Brazil. Techniques used to detect OCB consisted of isoelectric focusing followed by immunoblotting

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. Oligoclonal Bands are large groups of antibodies that can sometimes be found in the blood and in the cerebrospinal fluid, the CSF. They are caused by a state of inflammation in either the body or the Central Nervous System or both. This kind of inflammation is caused by the immune system which makes a colony of B-lymphocytes, by cloning one B.
