Measles antibodies as related to HL-A types in multiple sclerosis.
One hundred thirty-six patients with multiple sclerosis and several control groups were studied for measles antibodies using several different antigens. Measles antibodies were higher in the multiple sclerosis population, but siblings also had higher titers than matched and random controls. The elevation in antibody titers (complement fixation) was found in female multiple sclerosis patients and male patients with HL-A types 3, 7, and W-18. Male patients not carrying these HL-A antigens had, as a group, relatively normal antibody levels. These data confirm a familial factor in elevated measles antibody titers. We suggest that HL-A antigens are linked to one of the factors that determines measles antibody titers in multiple sclerosis patients.
