II. Pearls
- See Rheumatoid Arthritis Prediction Rule for Undifferentiated Arthritis
- History and Examination are most important
- Lab and x-ray add little help in diagnosis
- Erythrocyte Sedimentation Rate (ESR) may be normal
- C-Reactive Protein may be normal
- Rheumatoid Factor may be normal
- X-Ray may be normal
III. Indications: Evaluation for Rheumatoid Arthritis
- At least one joint with definite clinical synovitis or swelling and
- Synovitis not better explained by another condition
IV. Criteria: ACR/EULAR Rheumatoid Arthritis Diagnostic Criteria (2010)
- Joint Involvement
- Large joints: Shoulders, elbows, hips, knees and ankles
- Small joints: MTP, PIP, DIP and wrists
- Points 0: One large joint involved
- Points 1: Two to ten large joints involved
- Points 2: One to three small joints involved (with or without large joint involvement)
- Points 3: Four to ten small joints involved (with or without large joint involvement)
- Points 5: More than 10 joints involved (with at least one small joint involved)
-
Serology (Rheumatoid Factor, Anti-Citrullinated Protein Antibody)
- Points 0: RF negative and ACPA negative
- Points 2: Low positive RF or ACPA
- Points 3: High positive RF or ACPA
- Acute Phase Reactants (C-Reactive Protein, Erythrocyte Sedimentation Rate)
- Duration of symptoms
- Points 0: Less than 6 weeks
- Points 1: Six weeks or more
V. Interpretation
- Total score (four components above are added)
- Score of 6 or greater is needed for definitive diagnosis of Rheumatoid Arthritis

Definition (MEDLINEPLUS) |
Rheumatoid arthritis (RA) is a form of arthritis that causes pain, swelling, stiffness and loss of function in your joints. It can affect any joint but is common in the wrist and fingers. More women than men get rheumatoid arthritis. It often starts in middle age and is most common in older people. But children and young adults can also get it. You might have the disease for only a short time, or symptoms might come and go. The severe form can last a lifetime. Rheumatoid arthritis is different from osteoarthritis, the common arthritis that often comes with older age. RA can affect body parts besides joints, such as your eyes, mouth and lungs. RA is an autoimmune disease, which means the arthritis results from your immune system attacking your body's own tissues. No one knows what causes rheumatoid arthritis. Genes, environment and hormones might contribute. Treatments include medicine, lifestyle changes and surgery. These can slow or stop joint damage and reduce pain and swelling.

Definition (NCI_NCI-GLOSS) | An autoimmune disease that causes pain, swelling, and stiffness in the joints, and may cause severe joint damage, loss of function, and disability. The disease may last from months to a lifetime, and symptoms may improve and worsen over time. |
Definition (NCI) | A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. |
Definition (MSH) | A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. |
Definition (CSP) | chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures; etiology is unknown, but autoimmune mechanisms have been implicated. |
