Popis: Objectives To examine the prevalence of extra-musculoskeletal manifestations (EMM) and the association between diagnostic delay and their incidence in ankylosing spondylitis (AS) and psoriatic arthritis (PsA). Methods Retrospective, cohort study comprising two single centre cohorts in Europe and one multicentre cohort in Latin America (RESPONDIA). EMMs (uveitis, inflammatory bowel disease [IBD] and psoriasis) crude prevalence was calculated across geographic area and adjusted by direct standardisation. Cox proportional hazard analysis were performed to assess the association between diagnostic delay and EMM incidence. Results Of 3553 patients, 2097 had AS and 1456 had PsA. The overall prevalence of uveitis was 22.9% (95%CI 21.1–24.8) in AS and 3.8% (95%CI 2.9–5.0) in PsA; 8.1% (95%CI 7.0–9.4) and 2.1% (1.3–2.9) respectively for IBD; 11.0% (95%CI 9.7–12.4) and 94.6% (93.0–95.9) for psoriasis; with EMM often presenting before the arthritis (uveitis 45.1% and 33.3%; IBD 37.4% and 70% in AS and PsA respectively). In the multivariable model, longer diagnostic delay (≥5 years) associated with more uveitis (HR 4.01, 95%CI 3.23–4.07) and IBD events (HR 1.85, 95%CI 1.28–2.67) in AS. Diagnostic delay was not significantly associated with uveitis (HR 1.57, 95%CI 0.69–3.59) or IBD events (HR 1.59, 95%CI 0.39–6.37) in PsA. Conclusion EMMs are more prevalent in AS than PsA and often present before the onset of the articular disease. A longer diagnostic delay is associated with the “de novo” appearance of uveitis and IBD in AS, highlighting the need to enhance diagnostic strategies to shorten the time from first symptom to diagnosis in SpA.
