Title: Spondyloarthritis Including Psoriatic Arthritis – Clinical Poster II: Clinical/Epidemiology Studies
Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose: Uveitis is a common extra-articular manifestation in Spondyloarthritis (SpA). The purpose of this study was to analyze incidence of uveitis in SpA patients during the last decade and to evaluate the impact of the biologic therapies on this incidence.
Methods: This study is an ancillary analysis of the ASAS-COMOSPA study and included patients fulfilling ASAS SpA criteria from 22 countries. We calculated overall cumulative incidence of uveitis and evaluated difference across continents and clinical phenotypes. Patients were stratified according to date of disease onset [before 2000 and after 2000 (Biologics Era)]. We performed univariate and logistic multivariate models looking for risk factors associated with uveitis. A p-value of 0.05 was considered statistically significant.
Results: We included 3984 patients. 65% were male with a mean disease duration was 15 ±12 years and mean age at disease onset of 28 ±13 years. HLA-B27 were positive in 72%. 805 patients developed uveitis, with a cumulative incidence of 0.20 in 32137 patient-years from disease onset. Median time to develop uveitis was 9 (p25-p75=3-16) years and it was present at disease onset in 5% of patients. Inflammatory bowel disease (IBD) showed the higher frequency of uveitis (33%), enthesitis (24%), axial involvement (22%), peripheral arthritis (20%), dactylitis (19%) and psoriasis (13%). 94% of patients with IBD and 89% of patients with enthesitis, also presented axial involvement. 88% of patient with uveitis were HLA-B27 positive and 17% had first/second degree relatives with uveitis.Patients who meet ASAS Peripheral Criteria showed less frecuency of uveitis than those who meet ASAS Axial Criteria (11% vs 23%, p<0.01).Europe show a significantly higher cumulative incidence of uveitis (0.23) than Asia (0.20), Latin-America (0.17), North-America 0.15 and Africa 0.18.Patients with disease diagnosis after 2000 showed a lower cumulative incidence of uveitis than those with disease diagnosis before 2000 year (14% vs 27%, p<0.01).Risk factors associated with uveitis were HLA-B27 positive, family history of uveitis, enthesopathy and/or IBD. (table 1).
Conclusion: One fifth of patient with SpA developed uveitis.HLA-B27 positive and family history of uveitis were associated with higher risk of uveitis. Patients from Europe showed the highest frequency. Patients with disease onset after biologics development had a lower cumulative incidence of uveitis, but after adjust for multiple confounders, did not reach statistical significance.
