Ankle arthritis predicts poor outcomes in JIA

Children who develop ankle arthritis within a year of a juvenile idiopathic arthritis diagnosis are likely to have an unfavourable disease outcome, a Scandinavian study shows.

Ankle arthritis is common, occurring in 57% of 440 children in the Nordic JIA cohort, and it appears early on in the disease – on average seven months after the initial JIA diagnosis, the authors say.
