Juvenile rheumatoid arthritis (JRA) is a chronic inflammatory disorder that affects children under the age of 16. It is characterized by joint swelling, stiffness, and pain. JRA can be classified into several subtypes, including systemic onset, polyarticular onset, and oligoarticular onset. Systemic onset JRA is the most severe subtype, affecting multiple joints and causing systemic symptoms.
The exact cause of JRA is unknown, but it is believed to be an autoimmune disorder. The immune system mistakenly attacks healthy cells and tissues in the body, causing inflammation and damage. In systemic onset JRA, the immune system causes inflammation not only in the joints but also in other parts of the body, such as the liver, spleen, and lymph nodes. This can lead to systemic symptoms such as fever, rash, and fatigue.
JRA with systemic onset and multiple sites affects multiple joints and can cause damage to other organs. The symptoms can be severe and can have a significant impact on a child's quality of life. Treatment for JRA with systemic onset and multiple sites typically involves a combination of medication, physical therapy, and lifestyle changes. The goal of treatment is to relieve pain, reduce inflammation, and prevent joint damage.
If left untreated, JRA with systemic onset and multiple sites can lead to joint deformity, disability, and decreased quality of life. Early diagnosis and treatment are crucial for preventing these complications. If you suspect that your child may have JRA, it is important to consult with a healthcare provider.
In conclusion, JRA with systemic onset and multiple sites is a severe subtype of JRA that affects multiple joints and causes systemic symptoms. Treatment typically involves a combination of medication, physical therapy, and lifestyle changes. Early diagnosis and treatment are crucial for preventing joint damage and improving quality of life.
