title: Zinc in multiple sclerosis.
abstract: Zinc profiles were examined in 68 patients with multiple sclerosis, 62 normal volunteers, and 13 patients with other neurological diseases. Plasma zinc levels were slightly increased in patients with multiple sclerosis and significantly increased in those with other neurological impairments (p less than 0.01), compared with control subjects. Albumin-bound as well as protein-bound zinc levels were normal in all groups tested. The alpha 2 macroglobulin-bound zinc level was significantly lower (p less than 0.01) in patients with multiple sclerosis than in control subjects. Erythrocyte-bound zinc levels were significantly increased (p less than 0.05) in patients with multiple sclerosis when compared with control subjects. Erythrocyte-bound zinc was normal in patients with other neurological impairments. Because erythrocyte-bound zinc levels are relatively independent of daily fluctuations in dietary zinc intake, an increase in these values may suggest alterations in the control mechanisms governing zinc compartmentalization in patients with multiple sclerosis.
