Juvenile Rheumatoid Arthritis with Systemic Onset (JRA) is a type of juvenile arthritis that affects the entire body. It is also known as Systemic Juvenile Idiopathic Arthritis (SJIA). This condition usually affects children under the age of 16 and is more common in girls than boys.
The exact cause of JRA with systemic onset is not known. However, it is believed to be an autoimmune disorder. This means that the body's immune system attacks the healthy cells in the body, causing inflammation and pain.
The symptoms of JRA with systemic onset are different from other types of juvenile arthritis. The child may experience high fever, rash, joint pain, and swelling, as well as inflammation of the internal organs such as the heart and lungs. The symptoms may come and go, and the child may experience periods of remission.
In addition to medication, physical therapy can help to improve joint mobility and reduce pain. Occupational therapy can help the child to perform daily activities with less pain and discomfort. It is important for children with JRA with systemic onset to stay active and maintain a healthy weight to reduce stress on the joints.
In conclusion, JRA with systemic onset is a rare but serious condition that requires early diagnosis and treatment. If your child is experiencing joint pain, swelling, or other symptoms, it is important to see a doctor for an evaluation. With the right treatment, children with JRA with systemic onset can live healthy, active lives.
