<h3>Background</h3> PsA is a chronic, inflammatory disease characterised by peripheral arthritis, axial disease, dactylitis, enthesitis and skin and nail psoriasis. The impact of skin and joint components of the disease on quality of life and work productivity has been studied (1,2) but the impact of other manifestations has not. <h3>Objectives</h3> To assess the impact of enthesitis, dactylitis, and axial disease on quality of life and work productivity in PsA patients. <h3>Methods</h3> Cross-sectional study among patients with PsA recruited by rheumatologists and dermatologists in France, Germany, Italy, Spain, UK, and US. Data were collected from Jun-Aug 2018 via physician-completed patient record forms and patient self-completed forms. Physicians recorded (Yes/No) if patients currently presented with enthesitis, dactylitis, inflammatory back pain (IBP), and sacroiliitis (identified by x-ray or MRI). Multiple linear regression analyses were used to examine the impact of these manifestations on patient reported outcomes (PROs) including EQ-5D index, EQ-5D VAS, HAQ-DI, PsAID12, and WPAI. Models were adjusted for age, gender, number of joints affected, and time since diagnosis. There was no imputation of missing data. <h3>Results</h3> The sample included 1103 patients: mean age 47.6 [SD 13.2] years, 46% were female, 58% were working full time. Mean number of joints affected by PsA was 3.8 (SD 5.2), and 54.9% were receiving biologic treatment. Enthesitis (present in 6.3% of patients), dactylitis (8.0%) and IBP (12.6%) were associated with worse outcomes overall (Table 1); sacroiliitis (3.9%) was linked to worse physical function and quality of life. <h3>Conclusion</h3> In a multi-national, real-world PsA population, enthesitis, dactylitis, IBP, and sacroiliitis were significantly associated with worse patient quality of life and/or work productivity across a range of PROs independent of the number of joints affected. These manifestations should be considered alongside skin and joint components in order to optimize patient outcomes. <h3>References</h3> [1] Borman P, et al. Clin Rheumatol. 2007;26(3):330–4.
