Rheumatoid Arthritis ("RA") is a systemic disease that is caused by inflammation in the lining of the joints. The
cells in the joint lining (called the "synovium") release enzymes that break down bone and cartilage. RA affects
women twice as much as men and typically occurs between the ages of 30 and 50.
Because it is a chronic disease, RA continues indefinitely and may not go away. Frequent flares in disease activity can occur. RA is a systemic disease, which means it can affect other organs in the body. Early diagnosis and treatment of RA is critical if you want to continue living a productive lifestyle. Studies have shown that early aggressive treatment of RA can limit joint damage, which in turn limits loss of movement, decreased ability to work, higher medical costs and potential surgery.
RA affects 1.3 million Americans. Currently, the cause of RA is unknown, although there are several theories. And while there is no cure, it is easier than ever to control RA through the use of new drugs, exercise, joint protection techniques and self-management techniques. While there is no good time to have rheumatoid arthritis, advancements in research and drug development mean that more people with RA are living happier, healthier and more fulfilling lives.
Juvenile rheumatoid arthritis (JRA) is the most common form of arthritis in children. It is also called juvenile idiopathic arthritis (JIA) and juvenile chronic arthritis (JCA). It is often a mild condition that causes few problems over time, but it can be much more persistent and cause joint and tissue damage in other children. JA can produce serious complications in more severe cases.
Arthritis is best described by four major changes in the joints that may develop. The most common features of JRA are: joint inflammation, joint contracture (stiff, bent joint), joint damage and/or alteration or change in growth. Other symptoms include joint stiffness following rest or decreased activity level (also referred to morning stiffness or gelling), and weakness in muscles and other soft tissues around involved joints. However, because JRA affects each child differently, your child may not experience all of these changes. Children also vary in the degree to which they are affected by any particular symptom.
