[The sigma sedimentation rate in rheumatoid arthritis: comparative study of the erythrocyte sedimentation rate].
The authors studied 54 patients suffering from rheumatoid arthritis by sigma SR method. The sigma SR, unlike the ESR, often reveals inflammatory activity in patients suffering from possible or probable rheumatoid arthritis and is very useful to diagnose the disease. The sigma SR constantly increases when the disease is in active period, unlike the ESR, in patients affected by classic or definite rheumatoid arthritis. The authors conclude the sigma SR determination is useful in every case of rheumatoid arthritis, especially when the disease is at beginning and is difficult to be diagnosed, i.e. cases of possible and probable rheumatoid arthritis, and when clinical and biohumoral picture disagree.
