Summary
The levels of serum C-reactive protein (CRP) were found to be significantly higher in the presence than in the absence of secondary Sjögren's syndrome in patients with rheumatoid arthritis, while the values of erythrocyte sedimentation rate and serum fibrinogen were not significantly different. The levels of CRP were found to be normal in 22 out of 24 patients with primary Sjögren's syndrome.
