Juvenile rheumatoid arthritis (JRA) is the most common type of childhood arthritis. It causes joint inflammation for at least six weeks in children 16 years old or younger. Doctors believe that JRA is an autoimmune disorder meaning the body's immune system attacks its own cells and tissues. It is not known why this happens, but both heredity and environment seem to play a role. In most cases, symptoms of JRA may fade after several months or years.
A virus or bacterium may cause the development of juvenile rheumatoid arthritis in children with certain genetic profiles. These genetic profiles are detected in some children with JRA and are considered genetic markers. However, not all children with the markers develop JRA, and children without the markers can develop the condition.
Children with juvenile rheumatoid arthritis should live life as normally as possible by attending school and participating in extra-curricular and family activities. To foster a healthy transition to adulthood, adolescents with JRA should be allowed to enjoy independent activities, such as taking a part-time job and learning to drive. Provide your child with opportunities to interact with other children who also have arthritis in or near your community. Ask your rheumatologist about summer camps and other available group activities.
Treatment of juvenile rheumatoid arthritis focuses on physical activity to maintain full joint movement and strength, preventing damage and controlling pain. Continued physical activity will help prevent loss of function. Therapists may construct splints to prevent joint contractures or deformity, and work with school-based therapists to address issues at school.
Parents should be familiar with Federal Act 504, which may provide children with juvenile rheumatoid arthritis special accommodations at school. Families with children with JRA may be eligible for assistance through state agencies or services such as vocational rehabilitation. They may also benefit from information and activities available through the American Juvenile Arthritis Organization.
