title: Relationships between abnormal IgG index, oligoclonal bands, acute phase reactants and some clinical data in multiple sclerosis.
abstract: The IgG-index and acute phase reactants were measured and oligoclonal bands were looked for in 30 patients with clinically definite multiple sclerosis (MS) and were compared with the clinical data. IgG-index was found elevated in 77% against 22% in a comparable material of patients with other neurological diseases. Oligoclonal bands were found in 74 and 17%, respectively. No correlation was found between these parameters and age, duration of illness, disability, coefficient of progression or age of onset. A statistical evaluation defines the specificity, sensitivity and validity of the methods used. CRP could no be demonstrated in 28, the rest had normal values. C3A was normal in all cases, but appeared to be elevated a little with increasing age, and to be positively correlated to the albumin-index, indicative of a defective blood-brain barrier. No correlation was found between CRP, C3A and the clinical data.
