Juvenile rheumatoid polyarthritis (JRA) is a type of arthritis that affects children. It is a chronic autoimmune disorder that causes inflammation in the joints. JRA is also known as juvenile idiopathic arthritis (JIA) or juvenile chronic arthritis (JCA). Seronegative JRA is a subtype of JRA that is characterized by the absence of certain antibodies in the blood.
There are three types of JRA: oligoarticular JRA, polyarticular JRA, and systemic JRA. Seronegative JRA falls under the polyarticular subtype. It affects five or more joints in the body and can cause joint pain, stiffness, and swelling. Other symptoms may include fever, rash, and eye inflammation.
The exact cause of seronegative JRA is unknown, but it is believed to be caused by a combination of genetic and environmental factors. There is no known cure for JRA, but treatment options are available to manage symptoms and improve quality of life.
It is important for children with JRA to receive regular medical care and follow a treatment plan. Without treatment, JRA can lead to joint damage, growth problems, and other complications.
In conclusion, seronegative JRA is a type of arthritis that affects children and is characterized by the absence of certain antibodies in the blood. Treatment options are available to manage symptoms and improve quality of life. Regular medical care is important to prevent complications and ensure the best possible outcome.
