Methotrexate is an effective treatment for chronic uveitis associated with juvenile idiopathic arthritis.
OBJECTIVE
To assess the effectiveness of methotrexate (MTX) in the treatment of juvenile idiopathic arthritis (JIA) associated uveitis, which is still one of the most common causes of visual impairment.


METHODS
A retrospective chart review of patients with the diagnosis of uveitis associated with JIA between July 1, 2002, and December 31, 2002.


RESULTS
Four hundred sixty-seven patients with JIA were followed. Thirty-eight had uveitis: 31 associated with oligoarticular JIA and 7 with psoriatic JIA. Twenty-five of the 38 patients received MTX; in 23 patients uveitis was the indication for MTX therapy. In the MTX treated group 46/50 eyes had uveitis, the mean (range) age at onset of uveitis was 7.82 years (1.8-15.8), and the mean age at onset of arthritis was 7.25 years (1.25-15.7). MTX treatment was started an average of 11.4 months (0-72) after the onset of uveitis. The mean MTX dose was 15.6 mg/m2. Remission occurred after 4.25 months (1-12). Mean duration of remission was 10.3 months (3-27). The total duration of MTX therapy was 661 months and patients were in remission for 417/661 months. In 6 patients MTX was discontinued after 12 months of remission. Four patients were still in remission after 7.5 months (1-14).


CONCLUSIONS
MTX seems to be an effective therapy for JIA associated uveitis.
