Levels of IgD in patients with rheumatoid arthritis.

It has been proposed that IgD may have a pathophysiological role in certain autoimmune diseases, since antinuclear IgD antibodies were revealed in patients with systemic lupus erythematosus, rheumatoid arthritis and systemic sclerodermia. The studies on the problem of evaluation of serum IgD levels in patients with rheumatoid arthritis (RA) are scanty and their results are controversial. We studied IgD levels in patients with RA in order to demonstrate possible correlations with selected immunologic parameters, and to determine the relevance of IgD quantitation in the diagnosis of RA.
