The syndrome ordinarily emerges after years of seropositive, persistently active rheumatoid arthritis; however, vasculitis may occur when joints are inactive.

Addional information on vasculitis can be found on our Vasculitis Center website. The most common neurologic manifestation of rheumatoid arthritis is a mild, primarily sensory peripheral neuropathy, usually more marked in the lower extremities. Entrapment neuropathies e. Cervical myelopathy secondary to atlantoaxial subluxation is an uncommon but particularly worrisome complication potentially causing permanent, even fatal neurologic damage. This is characterized by splenomegaly, and leukopenia — predominantly granulocytopenia.
Recurrent bacterial infections and chronic refractory leg ulcers are the major complications.
The course of rheumatoid arthritis cannot be predicted in a given patient. Several patterns of activity have been described:. Recent studies have demonstrated an increased mortality in rheumatoid patients.

Median life expectancy was shortened an average of 7 years for men and 3 years for women compared to control populations. In more than patients with rheumatoid arthritis from four centers, the mortality rate was two times greater than in the control population. Patients at higher risk for shortened survival are those with systemic extra-articular involvement, low functional capacity, low socioeconomic status, low education, and prednisone use.
With the advent of therapies to better control inflammation and treatment strategies geared to low disease activity and remission, it is hoped that the statistics concerning disability and mortality will improve.
No laboratory test will definitively confirm a diagnosis of rheumatoid arthritis. However, the information from the following tests contributes to diagnosis and management. Similarly, the platelet count is usually normal but thrombocytosis occurs in response to inflammation. Chemistry tests are usually normal in rheumatoid arthritis with the exception of a slight decrease in albumin and increase in total protein reflecting the chronic inflammatory process. Renal and liver function are important to check before beginning treatment and are followed over time with many medications.
A positive Anti-CCP is a more specific marker for RA and is found in similar proportions of patients over the course of disease.
The inflammatory arthritis pathway
High levels of Anti-CCP also appear to be linked to a greater severity of the disease. Measures of inflammation are often, but not always increased in RA. The erythrocyte sedimentation rate ESR is usually elevated in patients with RA and in some patients is a helpful adjunct in following the activity of the disease. The C-reactive protein CRP is another measure of inflammation that is frequently elevated, and improves with control of disease activity.
Testing for hepatitis B and C and testing for tuberculosis are commonly done as part of an initial evaluation. Baseline X-Rays of the hands, feet, and other affected joints are common at initial evaluation, and sometimes a baseline chest X-Ray is obtained. Erosions of bone and destruction of cartilage, occur rapidly and may be seen within the first 2 years of the disease, but continue to develop over time See picture below.
These anatomic changes result in limitations in range of motion, flexion contractures, and subluxation incomplete dislocation of articulating bones. Typical deformities include ulnar deviation of the fingers at the MCP joints, hyperextension or hyperflexion of the MCP and PIP joints swan neck and boutonniere deformities , flexion contractures of the elbows, and subluxation of the carpal bones and toes hammer toes and cock up deformities.
Radiological findings early in the disease may show nothing other than soft tissue swelling. Thereafter, periarticular osteopenia may develop. With progression of their disease, narrowing of the joint space is caused by loss of cartilage, and juxta-articular erosions appear, generally at the point of attachment of the synovium.
