Rheumatoid Arthritis

What is rheumatoid arthritis?

Rheumatoid arthritis is a disease that causes pain, stiffness, swelling, and sometimes joint deformity. It occurs most commonly in the fingers, wrists, elbows, shoulders, jaw, hips, knees, and toes. It usually affects the same joint on both sides of the body (for example, both hips).

Rheumatoid arthritis often appears first in early adulthood or middle age. However, sometimes it does not occur until the later years. There may be one single attack, but more often the condition comes and goes in repeated episodes. The disease cannot be cured, but medicine can reduce the frequency and severity of attacks.

Rheumatoid arthritis affects 1 in every 100 Americans. It is three times more common in women than in men.

How does it occur?

Rheumatoid arthritis is thought to be an autoimmune disease. This means that the body's defenses against infection attack the body's own tissue. In rheumatoid arthritis, the result is that the lining of a joint becomes inflamed, causing swelling, stiffness, and deformity.

Heredity may make some people more likely than others to have rheumatoid arthritis.

What are the symptoms?

The symptoms may include:

• joint pain and stiffness, particularly morning stiffness
• red, warm, or swollen joints
• joint deformity
• mild fever, tiredness
• loss of appetite
• anemia
• small lumps or nodules under the skin.

In severe cases, there may be more widespread complications involving the circulatory system, blood vessels, and lymph glands.

How is it diagnosed?

Your health care provider will review your medical history and examine you. He or she may order blood tests and x-rays to confirm the diagnosis and measure the extent of the disease.

How is it treated?

The goal of treatment is to keep the joints working properly by reducing inflammation, relieving the pain and stiffness, and stopping or slowing down joint damage.

Your health care provider will prescribe medicine to control the pain and inflammation. Acetaminophen can often help with pain but will not reduce inflammation in the joint. Common medicines that control both pain and inflammation are aspirin and other anti-inflammatories such as ibuprofen and naproxen. Steroids are also sometimes used. Newer drugs for more severe cases are gold compounds (such as auranofin), methotrexate, and Plaquenil. It may be necessary to inject medicine directly into the joint. These medicines must be used with caution because of potential side effects and complications involving the kidneys, digestive system, and. Medicine for rheumatoid arthritis should be taken only after consulting with your health care provider.

Physical therapy helps restore use of affected joints and muscles. Occupational therapy teaches you how to overcome the disability and manage everyday tasks.

You may wear splints to rest inflamed joints and to prevent them from becoming deformed.

Sometimes severely damaged hips and knees are surgically replaced.

How long will the effects last?

You may have just one attack of rheumatoid arthritis in your life. More likely, however, you will have repeated flare-ups, and these flare-ups may become progressively worse. The flare-ups will vary in length and may last weeks.
