Rheumatoid Arthritis - Causes , Symptoms, Treatment

Feb. 12, 2011 - PRLog -- Aching joints are common in arthritis. In rheumatoid arthritis, the joint lining swells, invades surrounding tissues, and produces chemical substances that attack and destroy the joint surface.
People of all ages may be affected. The disease usually begins in middle age.
Rheumatoid arthritis usually affects joints on both sides of the body in the hands and feet, as well as the hips, knees, and elbows. Without proper treatment, rheumatoid arthritis can become a chronic, disabling condition.
Cause
Rheumatoid arthritis is not an inherited disease. Researchers believe that some people have genes that make them susceptible to the disease. People with these genes will not automatically develop rheumatoid arthritis. There is usually a "trigger," such as an infection or environmental factor, which activates the genes. When the body is exposed to this trigger, the immune system responds inappropriately. Instead of protecting the joint, the immune system begins to produce substances that attack the joint. This is what may lead to the development of rheumatoid arthritis.
Ligaments and joint capsules become less effective supporting structures. Erosion of the articular cartilage, together with ligamentous changes, result in deformity and contractures. As the disease progresses, pain and deformity increase.
Symptoms
Pain, morning stiffness, swelling, and systemic symptoms are common. Other rheumatoid symptoms include:
•   Swelling, pain, and stiffness in the joint, even when it is not being used
•   A feeling of warmth around the joint
•   Deformities and contractures of the joint
•   Symptoms throughout the body, such as fever, loss of appetite and decreased energy
•   Weakness due to a low red blood cell count (anemia)
•   Nodules, or lumps, particularly around the elbow
•   Foot pain, bunions, and hammer toes with long-standing disease
Patients with severe rheumatoid arthritis typically have multiple affected joints in the hands, arms, legs, and feet. Joints of the cervical spine may be involved as well.
Treatment
Although there is no cure for rheumatoid arthritis, there are a number of treatment options that can help relieve joint pain and improve functioning. The treatment plan is tailored to the patient's needs and lifestyle. Rheumatoid arthritis is often treated by a team of health care professionals. These professionals may include rheumatologists, physical and occupational therapists, social workers, rehabilitation specialists, and orthopaedic surgeons.
Medication
Medications used to control rheumatoid arthritis fall into two categories: those that relieve symptoms and those that have the potential to modify the course of the disease. Often, they are used together. Aspirin and ibuprofen can help reduce the pain and inflammation of rheumatoid arthritis. Disease-modifying drugs include methotrexate and sulfasalazine and gold injections.
Researchers are also working on biologic agents that can interrupt the progress of the disease. These agents target specific chemicals in the body to prevent them from acting on the joints.
Exercise and Therapy
Exercise is an important part of a treatment program. The physician and physical therapist may work with patients to develop an exercise program that helps strengthen the joints without stressing them. In some cases, a splint or corrective footwear may be required.
Surgery
Joint replacement surgery is also an option and is often effective in restoring function.
