    Multiple sclerosis (MS) patients show abnormal amino acid levels, particularly elevated serum glutamate during relapses. Glutamate levels gradually increase before relapse onset and slowly decrease afterward.

    Area of Science:

    • Neuroscience
    • Biochemistry

    Background:

    • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
    • Amino acid metabolism may play a role in the pathogenesis of MS.

    Purpose of the Study:

    • To investigate amino acid abnormalities in the sera of multiple sclerosis patients.
    • To identify specific amino acid alterations correlating with disease activity, particularly relapses.

    Main Methods:

    • Analysis of serum samples from multiple sclerosis patients.
    • Quantification of amino acid levels, with a focus on glutamate.

    Main Results:

    • Extensive amino acid abnormalities were detected in multiple sclerosis sera.
    • A consistent elevation in serum glutamate was observed, most pronounced during relapses.

  • Glutamate levels showed a gradual increase preceding clinical relapse onset, peaking during the relapse, and then slowly declining.

    • Conclusions:

    • Serum glutamate levels represent a potential biomarker for multiple sclerosis relapse activity.
    • The gradual rise and fall of glutamate suggest a dynamic process linked to disease exacerbations.
