Juvenile idiopathic arthritis (JIA) is the term used to describe a group of inflammatory articular disorders of unknown cause that begin before the age of 16 and last over 6 weeks. The term juvenile idiopathic arthritis was chosen to signify the absence of any known mechanism underlying the disorder and to highlight the necessity of excluding other types of arthritis occurring in well defined diseases (in particular arthritis occurring in association with infectious, inflammatory and haematooncologic diseases).
Biomarker and diagnostic research for juvenile idiopathic arthritis has been reported in the published literature.
5 FDA-approved treatments are available for juvenile idiopathic arthritis, including ADALIMUMAB (HUMIRA, approved 2002), mobic (MOBIC, approved 2000), and MELOXICAM (MELOXICAM, approved 2004). An additional 10 compounds hold orphan drug designation.
