Juvenile Rheumatoid Arthritis
Alternate Names : JRA, Juvenile Chronic Polyarthritis, Still's Disease
Definition Juvenile Rheumatoid Arthritis is a chronic, inflammatory disease resulting in joint pain and inflammation. It may result in joint damage. It usually occurs before age 16.
Overview, Causes, & Risk Factors
Juvenile Rheumatoid Arthritis (JRA) is a chronic inflammatory arthritis in children. It occurs in between 50-100 per 100,000 children in the United States. JRA is a general term for the most common types of arthritis in children. It is divided in to several categories:
-
Systemic JRA: This form, which occurs in about 10% of cases, involves joint pain and swelling as well as fevers and rash. It is similar to Adult Still's Disease. The cause of this form of JRA is unknown.
-
Polyarticular JRA: This form occurs in about 40% of cases and involves multiple joints that are painful and swollen. The cause of this form of JRA is unknown. Some children may have a positive Rheumatoid Factor and evolve into Rheumatoid Arthritis.
-
Pauciarticular JRA: This form occurs in about 50% of cases and involves only a few joints. Some of these children, in particular boys, will be HLA-B27 positive. Families with HLA-B27 are at increased risk for this arthritis.
