What is rheumatoid arthritis?
RA is the most common form of autoimmune arthritis, affecting more than 1.3 million Americans. Of these, about 75 percent are women. In fact, 1–3 percent of women may get rheumatoid arthritis in their lifetime. The disease most often begins between the fourth and sixth decades of life. However, RA can start at any age.
What causes Rheumatoid Arthritis?
RA is an autoimmune disease. This means that certain cells of the immune system do not work properly and start attacking healthy tissues — the joints in RA. The cause of RA is not known. Yet, new research is giving us a better idea of what makes the immune system attack the body and create inflammation. In RA, the focus of the inflammation is in the synovium, the tissue that lines the joint. Immune cells release inflammation-causing chemicals. These chemicals can damage cartilage (the tissue that cushions between joints) and bone.
How is rheumatoid arthritis diagnosed?
RA can be hard to detect because it may begin with subtle symptoms, such as achy joints or a little stiffness in the morning. Also, many diseases behave like RA early on. For this reason, if you or your primary care physician thinks you have RA, you should see a Rheumatologist.
How is rheumatoid arthritis treated?
Therapy for RA has improved greatly in the past 30 years. Current treatments give most patients good or excellent relief of symptoms and let them keep functioning at, or near, normal levels. With the right medications, many patients can achieve “remission” — that is, have no signs of active disease.
There is no cure for RA.
Common DMARDs include Methotrexate(Rheumatrex, Trexall, Otrexup, Rasuvo), lefluonamide (Arava),
Patients with more serious disease may need medications called biologic response modifiers or “biologic agents.” They can target the parts of the immune system and the signals that lead to inflammation and joint and tissue damage. FDA-approved drugs of this type include abatacept (Orencia), adalimumab (Humira), anakinra(Kineret), certolizumab (Cimzia), etanercept (Enbrel), golimumab (Simponi) infliximab (Remicade), rituximab (
