Complications

Rheumatoid arthritis is not fatal, but complications of the disease may shorten survival by a few years in some individuals. Although type 2 rheumatoid arthritis is progressive and there is no cure, over time the disease becomes less aggressive, and symptoms may even improve.

Treatments for RA are increasingly effective in slowing this debilitating disease, and some may even prevent initial destruction by aggressively reducing inflammation. If bone and ligament destruction and any deformities have occurred, however, the effects are permanent. It is essential, therefore, to seek a doctor's help as soon as symptoms develop. Side effects of the treatments often contribute to the severity of the disease.

Effect of Joint Disability and Pain on Daily Life

Affected joints can become deformed, and the performance of even ordinary tasks may be very difficult or impossible. According to one survey, 70% of patients with rheumatoid arthritis feel the disease prevents them from living a fully productive life. A 2000 study found that approximately one-third of people with RA stop working within 5 years of onset of the disease.

Complications in Other Areas of the Body

Rheumatoid arthritis can affect other parts of the body as well as the joints. Some patients with severe disease may then be at higher risk for complications such as the following:

• Peripheral Neuropathy. This condition affects the nerves, most often those in the hands and feet. It can result in tingling, numbness, or burning.
• Anemia. People with RA may develop anemia, which involves a decrease in the production of red blood cells.
• Scleritis. This is an inflammation of the blood vessels in the eye that can result in corneal damage.
• Infections. RA patients have a higher risk for infections, particularly from some of the immune-suppressing drugs that they take.
• Skin Problems. Skin problems are common, particularly on the fingers and under the nails. Some patients develop severe skin complications that include rash, ulcers, blisters (which may bleed in some cases), lumps under the skin, and other problems. Severe skin disease can reflects a more serious case of RA in general.
• Gastrointestinal Problems. Although patients may experience stomach and intestinal distress, one 2000 study reported lower rates of stomach and colorectal cancers among RA patients.
• Osteoporosis. Osteoporosis, a disorder in which bone density decreases, is more common than average in postmenopausal women with RA. The hipbone is particularly affected. The risk for osteoporosis also appears to be higher than average in men with RA who are over 60 years old.
• Lung Disease. Patients with RA are susceptible to chronic lung diseases.
• Heart Disease. Mounting evidence suggests that RA can increase the risk for heart disease, possibly because of the inflammatory response in RA, which may also injure arteries and heart muscle tissue. Some studies have reported that people with RA are 30 - 50% more likely to suffer heart vessel blockages and 60 - 70% more likely to die as result than people without RA. A smaller British study indicated that about half of RA patients are likely to have silent symptoms of heart disease, and that it tends to develop about 10 years earlier than in people without RA.
• Lymphoma and Other Cancers. Research suggests that patients with RA are four times more likely than healthy patients to develop non-Hodgkin’s lymphoma. There has also been concern that some RA treatments may increase the risk for lymphoma. Studies from 2006 indicate that RA’s chronic inflammatory process may play a role in the development of lymphoma. Researchers found that patients with very severe and long-term RA had a substantially increased risk of developing lymphoma. Other 2006 research suggests that RA drugs, such as biologic response modifiers, do not increase lymphoma risk, although they do increase skin cancer risk.
• Periodontal Disease. People with RA may be twice as likely as non-arthritic individuals to have periodontal disease. Chronic inflammation and immune dysfunction are central to both diseases.
• Pregnancy. Women with RA have an increased risk for premature delivery. They are also three times more likely than healthy women to develop hypertension during the last trimester of pregnancy.
