Albumin and immunoglobulin-G in the cerebrospinal fluid and the diagnosis of multiple sclerosis. 1985

H H Kamp, and P R Bär, and E H van den Doel, and A Elderson

Multiple sclerosis (MS) remains a diagnosis based mainly on clinical criteria. Definitive diagnostic tests are, despite numerous attempts, not available. However, some laboratory tests like electrophoresis of the cerebrospinal fluid proteins or the determination of immunoglobulin G in cerebrospinal fluid have proved useful in increasing the probability of MS. This paper describes how these laboratory tests have to be interpreted in relation to pathophysiological phenomena and how they correlate with each other. The electrophoresis of CSF proteins and the diagnostic quotients (Ralb and CSF-IgG-index) are valuable aids to the clinician. It especially can substantiate the diagnosis MS. The magnitude of the index cannot be correlated with the clinical stage of MS. The usefulness of these tests in terms of a possible gain of information in the diagnostic process is discussed.

D007525 Isoelectric Focusing Electrophoresis in which a pH gradient is established in a gel medium and proteins migrate until they reach the site (or focus) at which the pH is equal to their isoelectric point. Electrofocusing,Focusing, Isoelectric
D009103 Multiple Sclerosis An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.
