Retrospective study on the effects of immunosuppressive therapy in uveitis associated with rheumatic diseases in Korea.

This retrospective study of 432 patients was conducted between 2000 and 2009 to compare immunosuppressive therapy responses in uveitis accompanied or unaccompanied by rheumatic diseases. We divided patients into two groups: uveitis related or unrelated to rheumatic diseases. The clinical improvement after treatment was measured at the end of the observation period. Of the 432 patients with uveitis, 33 (7.6%) patients suffered from associated rheumatic diseases and 399 (92.4%) patients did not. The groups showed similar clinical features, but the mean age at onset of uveitis was lower in the rheumatic disease group (44.06 ± 2.13 years vs. 48.23 ± 0.81 years). The rheumatic diseases included spondyloarthropathy (31%), Behcet's disease (27%), rheumatoid arthritis (18%), systemic lupus erythematosus (15%), Sjogren's syndrome (6%), and mixed connective tissue disease (3%). Erythrocyte sedimentation rate and C-reactive protein level were increased in uveitis associated with rheumatic diseases, whereas ocular complications were not. The response to immunosuppressive therapy was significantly increased in cases of uveitis associated with rheumatic diseases (P < 0.05). Therefore, during early treatment, uveitis accompanied by rheumatic diseases showed better response to immunosuppressive therapy and less frequent complications.
