The PRINTO Evidence-based Revision of the International League Against Rheumatism (ILAR) Classification criteria for juvenile idiopathic Arthritis

Juvenile idiopathic arthritis (JIA) is an exclusion diagnosis that encompasses all forms of otherwise unexplained chronic non-infectious arthritis occurring under the age of 16. Various attempts have been made to classify this heterogeneous group of diseases with the aim of identifying mutually exclusive categories suitable for etiopathogenetic studies. Since then increasing evidence has accumulated suggesting that some of these categories are heterogeneous. Therefore, there is a need to revise the criteria in order to identify more homogeneous entities and to try to distinguish those diseases. The main reason for this research study is to learn more about the diagnosis of Juvenile Idiopathic Arthritis (JIA) according to the ILAR (International League of Associations for Rheumatology) criteria and investigate a new classification criteria proposed by the international research organization Paediatric Rheumatology International Trials Organisation (PRINTO) and the Pediatric Rheumatology Collaborative Study Group (PRCSG).
