Abstract

To determine the specificity of antibodies to the (U1) ribonucleoprotein antigen in systemic lupus erythematosus (SLE), patient sera were tested for binding to a recombinant human 70K antigen. By solid-phase immunoassay, we detected anti-70K reactivity in sera from 31 of 96 patients with systemic lupus erythematosus (SLE), demonstrating that anti-70K antibodies may occur in patients with SLE as well as other clinical diagnoses. In sequential sera from 2 of these patients, we found that anti-70K binding varied dramatically over the course of disease. The changes in anti-70K antibody levels did not correlate with clinical events nor evolving antibody reactivity with the Sm-specific antigens.
