There is an association between rheumatoid factor and more persistently active synovitis, more joint damage, greater eventual disability and arthritis. [12] [13] Other than in rheumatoid arthritis, rheumatoid factor may also be elevated in other conditions, including: Systemic lupus erythematosus (SLE) [14] [15] Sjögren syndrome [14] [15]
The typical rheumatoid nodule may be a few millimetres to a few centimetres in diameter and is usually found over bony prominences, such as the elbow, the heel, the knuckles, or other areas that sustain repeated mechanical stress. Nodules are associated with a positive RF (rheumatoid factor) titer, ACPA, and severe erosive arthritis. Rarely ...
RA33, also known as heterogeneous nuclear ribonucleoprotein A2/B1, is an autoantigen in human systemic autoimmune diseases.. In 1989, a novel class of autoantibodies was detected in sera of patients with rheumatoid arthritis (RA), which were directed against a protein with an estimated molecular mass of 33 kDa in nuclear extracts from HeLa cells.

Other rheumatological disorders that can cause the features typical for RS3PE include late onset (seronegative) rheumatoid arthritis, acute sarcoidosis, ankylosing spondylitis and other spondyloarthropathies such as psoriatic arthropathy, mixed connective tissue disease, chondrocalcinosis and arthropathy due to amyloidosis.

Their significance is greater than that of rheumatoid factor. Recently a serological point-of-care test (POCT) for the early detection of RA has been developed. This assay combines the detection of rheumatoid factor and anti-MCV for diagnosis of rheumatoid arthritis and shows a sensitivity of 72% and specificity of 99.7%. [4] [5]
