Which type of juvenile idiopathic arthritis (JIA) is characterized by involvement of 4 or fewer joints and is most common in young girls?

Juvenile idiopathic arthritis (JIA) is a chronic inflammatory condition that affects children and is classified into different types based on clinical presentation. The type characterized by involvement of 4 or fewer joints is known as pauciarticular juvenile idiopathic arthritis.

This subtype is indeed most common in young girls and typically presents with inflammation of a limited number of joints, often large joints such as the knees or ankles. Additionally, pauciarticular JIA can have an associated risk of developing uveitis, which can have significant implications for eye health.

Understanding the demographics and symptomatic presentation of this subtype can help in early diagnosis and monitoring, which is crucial for minimizing long-term joint damage and functional impairment in affected children. The correct recognition of pauciarticular JIA is essential for clinicians to appropriately manage treatment and surveillance for potential complications.
