A review of clinical and laboratory findings and treatment of Juvenile Idiopathic Arthritis (JIA)

Juvenile idiopathic arthritis (JIA) refers to a group of disorders characterized by chronic arthritis. It is a chronic rheumatic disease and one of the major causes of disability in children. The diagnosis of JIA disease in children younger than 16 years with arthritis (swelling or effusion or two about decreased range of motion، warmth، pain or tenderness) for at least 6 weeks and rule out of other causes of arthritis with which they would be identifiable. The incidence and prevalence of JIA from 1 to 20 per 100،000 to 400 per 100،000 have been reported. There are several separated classification criteria for patients under 16 years of age who have chronic arthritis. The most practical and acceptable criteria are presented by American College of Rheumatology (ACR)، European League against Rheumatism (EULAR)، and the International League of Associations for Rheumatology (ILAR). Furthermore، spondyloarthritis in young children، including psoriatic arthritis and ankylosing spondylitis are being diagnosed with difficulty. Here in we discussed about chronic arthritis in children and the differences between these classification criteria.
