What alteration is commonly associated with juvenile idiopathic arthritis?

• A. Autoimmune response
• B. Infection
• C. Hormonal imbalance
• D. Genetic mutation

Answer: (A)

Juvenile idiopathic arthritis (JIA) is characterized primarily by an autoimmune response, where the body's immune system mistakenly targets its own joint tissues, leading to inflammation and pain. This condition manifests as chronic joint inflammation in children and can significantly impact their growth and development. The autoimmune nature of JIA differentiates it from other types of arthritis that may be caused by infections, hormonal changes, or genetic mutations. Autoimmune disorders can lead to a variety of symptoms and complications due to the body's overactive response to perceived threats. In the case of JIA, this inappropriate immune activity primarily affects the synovial membrane of the joints, resulting in swelling, stiffness, and potential joint damage over time.
