Abstract

Autoantibodies may be found years before an autoimmune disease becomes clinically apparent. For systemic lupus erythematosus (SLE), those to RNA-binding proteins, to phospholipids, and to double-stranded DNA, in particular, have been found in sera of SLE patients years before the diagnosis was made. New data now show in an unbiased way that, in patients with early SLE, no single antibody class or specificity is associated with progression to SLE. Rather, an increasing number of autoantibody specificities, such as to thyroid antigens, was observed in patients progressing. This points to more generalized B cell autoreactivity during progression to SLE, underlying lupus disease manifestations.
