Observational Prospective Turkish Inception Cohort of Uveitis and Spondyloarthritis

Conditions studied: Spondylarthritis, Uveitis, Anterior

In brief

Spondyloarthritis (SpA) encompasses a group of inflammatory rheumatic diseases characterized by axial and/or peripheral arthritis, along with extra-articular manifestations such as enthesitis, dactylitis, uveitis, and skin lesions. Axial spondyloarthritis (axSpA), the hallmark of which is chronic sacroiliitis, can progress to vertebral fusion ("bamboo spine") in advanced cases. The prevalence of axSpA varies globally, ranging from 0.1% to 1.4%, with a higher incidence in men and a typical onset in the second or third decades of life. Diagnostic approaches include imaging techniques such as sacroiliac MRI and radiographs, alongside clinical criteria like inflammatory back pain, NSAID responsiveness, peripheral arthritis, and HLA-B27 positivity. Disease management primarily involves NSAIDs, with biologics used for refractory cases, and disease activity is monitored using indices such as BASDAI and ASDAS. Acute anterior uveitis (AAU) is the most common extra-articular manifestation of SpA, particularly associated with HLA-B27 positivity. It often presents unilaterally with redness, pain, and photophobia but can lead to severe complications if inadequately treated. Around 50% of patients with HLA-B27-positive AAU have underlying SpA, and the prevalence of uveitis increases with longer disease duration. While the link between SpA and AAU is well-established, further research is needed to determine optimal systemic treatment and follow-up protocols. This study aims to assess the prevalence and clinical characteristics of SpA in patients presenting with AAU at ophthalmology clinics.
