7S and 19S Isoagglutinins in Systemic Lupes Erythematosus.
The 7S and 19S distribution of blood group isoantibodies (isoagglutinins) has been measured in patients with systemic lupus erythematosus. The only possibly significant finding was a lower level of macroglobulin isoagglutinin to B cells in patients of blood type A. This is consistent with previous findings of lessened response to bacterial antigens by the macroglobulin antibody.
