Enthesitis-related JIA is a type of juvenile idiopathic arthritis (JIA).
- This form of JIA affects the places where tendons attach to the bone (these places are called entheses), causing inflammation. It often affects the joints of the leg and spine.
- In contrast to the uveitis seen with the other types of JIA, this type of JIA is associated with a red painful eye, acute uveitis.
- You may develop stiffness in the neck and lower back in your teens or as a young adult.
- There may be a family history of ankylosing spondylitis or inflammatory bowel disease because of a particular genetic marker called HLA-B27.
