people with RA do not experience the same chest pain that others feel when they have angina or myocardial infarction. To reduce cardiovascular risk, it is crucial to maintain optimal control of the inflammation caused by RA (which may be involved in causing the cardiovascular risk), and to use exercise and medications appropriately to reduce other cardiovascular risk factors such as blood lipids and blood pressure. Doctors who treat people with RA should be sensitive to cardiovascular risk when prescribing anti-inflammatory medications, and may want to consider prescribing routine use of low doses of aspirin if the gastrointestinal effects are tolerable. Blood Anemia is by far the most common abnormality of the blood cells which can be caused by a variety of mechanisms. The chronic inflammation caused by RA leads to raised hepcidin levels, leading to anemia of chronic disease where iron is poorly absorbed and also sequestered into macrophages. The red cells are of normal size and color (normocytic and normochromic). A low white blood cell count usually only occurs in people with Felty's syndrome with an enlarged liver and spleen. The mechanism of neutropenia is complex. An increased platelet count occurs when inflammation is uncontrolled. Other The role of the circadian clock in rheumatoid arthritis suggests a correlation between an early morning rise in circulating levels of pro-inflammatory cytokines, such as interleukin-6 and painful morning joint stiffness. Kidneys Renal amyloidosis can occur as a consequence of untreated chronic inflammation. Treatment with penicillamine or gold salts such as sodium aurothiomalate are recognized causes of membranous nephropathy. Eyes The eye can be directly affected in the form of episcleritis or scleritis, which when severe can very rarely progress to perforating scleromalacia. Rather more common is the indirect effect of keratoconjunctivitis sicca, which is a dryness of eyes and mouth caused by lymphocyte infiltration of lacrimal and salivary glands. When severe, dryness of the cornea can lead to keratitis and loss of vision as well as being painful. Preventive treatment of severe dryness with measures such as nasolacrimal duct blockage is important. Liver Liver problems in people with rheumatoid arthritis may be due to the underlying disease process or as a result of the medications used to treat the disease. A coexisting autoimmune liver disease, such as primary biliary cirrhosis or autoimmune hepatitis may also cause problems. Neurological Peripheral neuropathy and mononeuritis multiplex may occur. The most common problem is carpal
