Features: Juvenile idiopathic arthritis (JIA) is a common connective tissue disease in children, usually occurring in children under the age of 16. In addition to joint symptoms and deformities, systemic symptoms are often prominent, such as intermittent fever, rash, hepatosplenomegaly and lymphadenopathy, pleuritis, and pericarditis. Younger children often present with intermittent fever first, with systemic symptoms being more pronounced than joint symptoms. Older children are more likely to exhibit joint symptoms. Although this condition is referred to as juvenile idiopathic arthritis, most children with this condition test negative for rheumatoid factor (RF), while only 5%-10% of polyarticular cases test positive. With treatment, the condition often improves and may even resolve spontaneously. If it recurs repeatedly, it may eventually lead to joint deformity and loss of function. This condition has a genetic predisposition, and there is often a history of similar cases among close relatives.
