    Low selenium (Se) levels in Finnish multiple sclerosis (MS) patients may indicate a nutritional link. This contrasts with animal muscular dystrophy, also linked to Se deficiency in the same region.

    Area of Science:

    • Nutritional science
    • Neurology
    • Veterinary medicine

    Background:

    • A Finnish district shows high rates of both cattle nutritional muscular dystrophy and human multiple sclerosis (MS).
    • Cattle disease is linked to deficiencies in selenium (Se) and vitamin E.
    • This geographic overlap suggests a potential shared etiological factor.

    Purpose of the Study:

    • To investigate potential links between selenium levels and MS in a high-risk Finnish population.
    • To compare blood Se and vitamin E levels in MS patients and controls from the affected region.

    Main Methods:

    • Whole blood and serum samples were collected from MS patients and healthy controls.
    • Selenium (Se) and vitamin E concentrations were measured.
    • Results were compared between groups and with international reference values.

    Main Results:

    • MS patients from the high-risk area had significantly lower whole blood Se levels compared to controls.
    • Serum Se levels did not show a significant difference between groups.
    • All measured Se values were below suggested international standards.
    • Vitamin E and copper levels were within the normal international range for both groups.

    Conclusions:

    • Lower whole blood selenium may be associated with multiple sclerosis in this specific Finnish region.
    • Further research is needed to confirm the role of selenium and vitamin E in MS etiology.
    • The findings warrant investigation into regional nutritional deficiencies as a contributing factor to MS.
