Factors That May Be Associated With Uveitis In Patients With Spondyloarthritis
Background/Purpose: It is known that uveitis is present in the extra-articular findings of spondyloarthritis (SPA) patients. Sufficient information is available in the literature on the frequency and characteristics of uveitis in SpA patients. The factors associated with uveitis in SPA patients are not clear. In this study, uveitis-related factors were analyzed in SPA patients in a large cohort.
Methods: In patients with and without uveitis, age, gender, duration of illness, delayed onset, body mass index, educational status, smoking habit, SPA subgroup, SPA clinical findings as well as co-morbid diseases, HLA B27 and acute phase responses, VAS pain, VAS patient global, VAS fatigue, BASDAI and BASFI values, swollen and painful joint counts, and direct X-ray findings were evaluated retrospectively. The history of uveitis was accepted only if diagnosed by ophthalmologists.
Results: As of May 2018, there are 2359 registered SPA patients. Among the total number of patients, 2096 patients had axial spondyloarthropathy (axSPA) (1249 ankylosing spondylitis, 100 non-radiographic aSPA), 179 psoriatic arthritis, 50 peripheral SPA and 51 enteropathic arthritis. Overall, 269 (11.4%) patients had experienced one or more episodes of uveitis. Median (Q1-Q3) uveitis beginning age was 36 (27-43) years. Duration between SpA symptom beginning age and first uveitis attack were 6.8 (2.6-12.8) years. Median (Q1-Q3) uveitis attacks number was 2 (1-4). Uveitis was usually unilateral (78.9%). 19/184 (10.3%) patients had permanent damage in the eye. Patients with permanent eye damage had more frequent uveitis attack (4 (2-10) vs 2 (1-3), p=0.018), and had tendency of bilateral uveitis attack (37.5% vs 16.6%, p=0.082). Demographic and clinical feature of patients were given in table 1. In multivariate analysis, only disease duration was related with uveitis OR 1.069 (1.05-1.09).
Conclusion: In our cohort, genetic background, radiographic severity, enthesis, and particularly disease duration may be related with uveitis. Although uveitis is usually self-limited, however almost 10% of SpA patients may have permanent eye damage.
