Abstract

The association between uveitis and spondyloarthritis is well established. However, its characterization across the different types of spondyloarthritis remains limited in the literature. Therefore, this study aimed to perform a comparative characterization of uveitis in the various types of spondyloarthritis.
Retrospective observational study that included patients with non-infectious uveitis and spondyloarthritis from a multidisciplinary uveitis clinic. A descriptive analysis was performed across the different subtypes of spondyloarthritis, followed by a comparative analysis regrouping patients into axial and peripheral SpA categories.
163 patients with spondyloarthritis-associated uveitis were included, comprising radiographic axial spondyloarthritis (49%), non-radiographic axial spondyloarthritis (21%), spondyloarthritis associated with inflammatory bowel disease (13%), psoriatic arthritis (12%), and peripheral spondyloarthritis (4%). Anterior uveitis (97%), acute relapsing course (79%), and alternating laterality (47.4%) were predominant in the overall sample. When comparing axial versus peripheral forms, significant differences were observed: intermediate, posterior, and panuveitis locations occurred exclusively in the peripheral forms, which also showed higher frequencies of chronic courses (p < 0.001), bilateralism (p < 0.05), and greater use of systemic therapy (p = 0.05). Regarding this treatment to control uveitis, 28.2% of patients required immunomodulatory therapy (more sulfasalazine in axial forms, and methotrexate in peripheral) and 17.8% required biologic therapy. Biologic discontinuation was higher in peripheral forms (p = 0.059). Variables predicting greater need for systemic therapy included chronic course, bilateralism, higher number of annual episodes, younger age of onset, peripheral joint involvement, and presence of vitritis (all p < 0.05).
Acute anterior uveitis constitutes the most frequent pattern in all spondyloarthritis types. However, peripheral forms exhibit a higher prevalence of non-anterior, chronic, and bilateral uveitis, and, additionally, appeared to require greater use of immunomodulatory therapy. Key Points • Understanding and distinguishing the ocular inflammatory processes associated with SpA may have important therapeutic and prognostic implications. • Although acute recurrent anterior uveitis was the most frequent patternacross all SpA subtypes, in the peripheral SpA group (pSpA, IBD-SpA, and PsA) a higher prevalence of intermediate, posterior, panuveitis, chronic course, and bilateral uveitis was observed. • The peripheral SpA group (pSpA, IBD-SpA, and PsA) appeared to require greater use of immunomodulatory drugs (csDMARDs or biologics) for control of the ocular condition, suggesting the need for closer monitoring and tailored therapeutic strategies.
