Sequential changes in oligoclonal patterns during the course of multiple sclerosis.

E J Thompson, P Kaufmann, P Rudge

    Journal of Neurology, Neurosurgery, and Psychiatry
    |February 1, 1983
    PubMed
    Summary

    Most multiple sclerosis patients show abnormal spinal fluid immunoglobulins, forming distinct oligoclonal patterns. Longitudinal studies reveal changes in these patterns, potentially impacting disease pathogenesis understanding.

    Area of Science:

    • Neurology
    • Immunology
    • Biochemistry

    Background:

    • Multiple sclerosis (MS) is characterized by central nervous system inflammation.
    • Abnormalities in cerebrospinal fluid (CSF) immunoglobulins are common in MS patients.
    • Electrophoresis reveals characteristic patterns of protein bands in the gamma globulin region, known as oligoclonal banding.

    Purpose of the Study:

    • To investigate the significance of changes in spinal fluid immunoglobulin patterns in multiple sclerosis.
    • To explore the relevance of longitudinal changes in oligoclonal banding for understanding MS pathogenesis.
    • To discuss the impact of methodologies and specific immunoglobulin classes (IgM, IgA) on interpreting these findings.

    Main Methods:

    • Analysis of spinal fluid immunoglobulin patterns using electrophoresis.

  • Longitudinal study design to track changes in banding patterns over time.
  • Evaluation of the role of IgM and IgA in the interpretation of electrophoretic results.

    • Main Results:

    • The majority of multiple sclerosis patients exhibit abnormal spinal fluid immunoglobulin patterns.
    • Observed changes in the oligoclonal banding patterns in some patients during longitudinal studies.
    • Highlighted the importance of specific methodologies and immunoglobulin types (IgM, IgA) for accurate interpretation.

    Conclusions:

    • Spinal fluid immunoglobulin abnormalities, specifically oligoclonal banding, are prevalent in multiple sclerosis.
    • Longitudinal changes in these patterns may offer insights into the waxing and waning nature of MS.
    • Methodological considerations and the inclusion of IgM and IgA are crucial for a comprehensive understanding of MS immunopathology.
