Enthesitis-related JIA

A guide for teenagers

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.

You can read more about enthesitis-related JIA on our JIA pages.
