title: Serum IgD and IgE in rheumatoid arthritis.
abstract: Serum immunoglobulins IgD and IgE have been determined by a single radial immunodiffusion technique and a radioimmunoassay method in serum samples from 95 rheumatoid patients, 5 subjects with Sjögren's syndrome and 50 healthy controls, and compared with levels of IgG, IgM and IgA fractions measured in the same subjects. The IgD and IgE serum content resulted similar in the rheumatoid, Sjögren's and control sera. No correlation of IgD and IgE values with changes of other immunoglobulins or with the activity and the duration of the rheumatoid disease was observed.
