  • Title: Cerebrospinal fluid autoantibodies to myelin basic protein in multiple sclerosis patients. Detection during first exacerbations and kinetics of acute relapses and subsequent convalescent phases.

    Journal: J Neurol Sci; 1989 Jun; 91(1-2):143-51. PubMed ID: 2473170.
    Abstract:
    In order to determine if free (F) and bound (B) levels of autoantibodies to myelin basic protein (anti-MBP) are present from the onset of multiple sclerosis (MS), 201 patients referred to our clinic were clinically divided into a group diagnosed as having an initial MS relapse and a group of non-MS controls. Ninety-four of 106 patients thought to have an initial MS relapse had increased CSF anti-MBP, while only 14 of 95 controls had elevated antibody levels; 9 of these 14 positive controls were subsequently shown to have MS by magnetic resonance imaging and/or clinical follow-up. CSF anti-MBP was more frequently abnormal than 3 estimates of intrathecal IgG synthesis in the group with suspected MS. Kinetics of F and B CSF anti-MBP were determined in a group of 29 patients with clinically definite MS during an acute relapse and 97.4 +/- 54 days later in the subsequent convalescent phase when in clinical remission. F and B anti-MBP levels were highly dependent on the timing of the CSF sampling; generally, as patients entered into clinical remission F anti-MBP declined, B antibody levels rose and F/B anti-MBP ratios initially above unity gradually declined towards zero. These data suggest that anti-MBP may be involved in the mechanism of MS.
