    This study found malabsorption issues in over 40% of multiple sclerosis patients, with evidence of measles virus antigen and immune reactions in the jejunum. These findings suggest a potential link between viral infections and the disease's development.

    Area of Science:

    • Neurology
    • Gastroenterology
    • Immunology

    Background:

    • Multiple sclerosis (MS) is a chronic neurological disease.
    • The pathogenesis of MS remains incompletely understood.
    • Gastrointestinal involvement and potential infectious triggers in MS are areas of active research.

    Purpose of the Study:

    • To investigate malabsorption and jejunal mucosal abnormalities in patients with multiple sclerosis.
    • To explore the presence of viral antigens and immune responses within the jejunal mucosa of MS patients.
    • To assess the potential role of these findings in the pathogenesis of multiple sclerosis.

    Main Methods:

    • Microscopic stool examination for fat and meat fibers.
    • D-xylose excretion tests and Vitamin B12 malabsorption assessment.

  • Histological examination of jejunal mucosa and immunofluorescent studies for viral antigens (measles virus) and immune reactions.

    • Main Results:

    • Abnormalities in fat and meat fiber excretion were observed in 41.6% and 40.9% of MS patients, respectively.
    • 26.6% of patients showed low d-xylose excretion, and 11.9% exhibited Vitamin B12 malabsorption.
    • Measles virus antigen was detected in all patients' jejunal mucosa, with significant immune reactions in most.

    Conclusions:

    • A significant proportion of multiple sclerosis patients exhibit signs of malabsorption.
    • The presence of measles virus antigen and immune responses in the jejunum suggests a potential viral contribution to MS pathogenesis.
    • Further research is warranted to elucidate the precise mechanisms linking gut abnormalities, viral presence, and multiple sclerosis development.
