What does matching oligoclonal bands mean?

An oligoclonal band is a protein called an immunoglobulin. The CSF oligoclonal band screen looks for these bands in your CSF. Their presence suggests inflammation of the central nervous system due to infection or another disease. If similar bands aren’t present in your blood, you may have multiple sclerosis (MS).

What is OCB test?

Oligoclonal bands (OCBs) are bands of immunoglobulins that are seen when a patient’s blood serum, or cerebrospinal fluid (CSF) is analyzed. They are used in the diagnosis of various neurological and blood diseases, especially in multiple sclerosis.

Are oligoclonal bands specific for MS?

Oligoclonal Bands in CSF—How Likely Is It MS? It is well-known that OCB in CSF are not exclusively found in MS. OCB are thought to indicate chronic immune-activation in the CNS and therefore, can be found in a variety of chronic inflammatory diseases.

What conditions show oligoclonal bands in CSF?

Oligoclonal bands were detected in the CSF of 95% of the patients with multiple sclerosis, 90% with subacute sclerosing panencephalitis, and 100% with herpes simplex encephalitis, but less frequently in other central nervous system infections.

Can you still have MS without oligoclonal bands?

Forms of MS without oligoclonal banding or with a very small number of bands are generally considered to be more benign and atrophy of the cerebral cortex is less. However, the presence of such bands is a predictive factor for a more rapid evolution and a more severe disability.

Can oligoclonal bands be normal?

Normal results are reported when no immunoglobulin proteins, called oligoclonal bands, are found in your cerebrospinal fluid. It is abnormal when there are more than two oligoclonal bandings discovered in your cerebrospinal fluid and also absent in your bloodstream.

Are oligoclonal bands normal?

Oligoclonal bands can be present even when the CSF IgG level is normal. Approximately 2% to 3% of clinically confirmed MS patients show little or no evidence of oligoclonal bands in the CSF; however oligoclonal bands may develop as the disease progresses.

How many oligoclonal bands indicate MS?

NASHVILLE—Patients with multiple sclerosis (MS) and 10 or more oligoclonal bands (OCBs) in CSF may have significantly more clinical and radiographic relapses and clinical progression during short-term follow-up than those who have fewer OCBs, according to data described at the 2018 CMSC Annual Meeting.

What diseases cause oligoclonal bands in CSF and serum?

Oligoclonal bands in CSF have been reported in cases of neurosyphilis, acute bacterial or viral meningitis, progressive multifocal leukoencephalopathy, subacute sclerosing panencephalitis, progressive rubella panencephalitis, polyneuritis, optic neuritis, trypanosomiasis, and other infectious or autoimmune diseases.

What conditions show oligoclonal bands in CSF but not serum?

Oligoclonal bands are suggestive, but not pathognomic of Multiple Sclerosis, being found in infective and inflammatory diseases of the CNS e.g viral encephalitis, bacterial meningitis, neurosyphilis, sarcoid and lupus.

Is MOG a type of MS?

MOG is a glycoprotein uniquely expressed in oligodendrocytes in the CNS. MOG antibodies were originally thought to be involved in multiple sclerosis (MS), but subsequent studies found it to be a distinct disease.

Can oligoclonal bands go away?

However, a very recent study has shown that in 24 MS patients treated with Tysabri, oligoclonal bands disappeared completely in 55 % of the cases and partly in 27 %. These results need to be confirmed on a larger number of patients.

What is the definition of an oligoclonal band?

Oligoclonal bands are defined as at least two bands seen in the CSF lane with noncorresponding band present in the serum lane. Thus, it is crucial to perform CSF and serum electrophoresis simultaneously. Oligoclonal bands may be found in 95% or more of patients with clinically definite MS [36].

What does oligoclonal banding in CSF mean?

CSF is the clear fluid that flows in the space around the spinal cord and brain. Oligoclonal bands are proteins called immunoglobulins. The presence of these proteins indicates inflammation of the central nervous system. The presence of oligoclonal bands may point to a diagnosis of multiple sclerosis. A sample of CSF is needed.

What are oligoclonal bands in cerebrospinal fluid?

Oligoclonal bands in multiple sclerosis cerebrospinal fluid: an update on methodology and clinical usefulness Two or more oligoclonal IgG bands (OB) detected by separation of cerebrospinal fluid (CSF) proteins while not demonstrable in corresponding serum reflect a local B-cell response accompanying central nervous system (CNS) inflammation.

What is an oligoclonal band in serum electrophoresis?

The immunoglobulin increase is predominantly IgG, although the synthesis of IgM and IgA may also be increased. Oligoclonal bands are defined as at least two bands seen in the CSF lane with noncorresponding band present in the serum lane. Thus, it is crucial to perform CSF and serum electrophoresis simultaneously.
