To compare disease characteristics, quality of life (QOL), and work productivity of patients with psoriatic arthritis (PsA) who had multidomain vs single-domain presentations.Adults with PsA enrolled in the Corrona PsA/SpA Registry (March 2013-August 2018) were included. Six PsA disease domains were evaluated: enthesitis, dactylitis, peripheral arthritis (PA), nail psoriasis, axial disease, and skin disease. Patients were classified as having multidomain ( 2 domains) or single-domain disease presentations; biologic initiators were characterized separately. Linear regression models evaluated the association of multidomain presentations with disease characteristics, QOL, and work productivity vs single-domain presentations.Of 2617 patients with PsA, 1698 (64.9%) had multidomain presentations, 617 (23.6%) had single-domain presentations, and 302 (11.5%) had no active disease features. Of 354 biologic initiators, 289 (81.6%) had multidomain presentations, 45 (12.7%) had single-domain presentations, and 20 (5.6%) had no active disease features. Overall, the most common singledomain and multidomain presentations, respectively, were skin disease (12.7%) and PA + skin disease (11.7%). Multidomain presenters were more likely to have fibromyalgia, depression, anxiety, and prior biologic use than single-domain presenters. Multidomain presentations were associated with significantly worse patient and physician global assessments of disease activity, pain, and fatigue; Health Assessment Questionnaire Disability Index and EQ-5D scores; and work productivity at enrollment.In this US real-world cohort, most patients had multidomain disease presentations, which was associated with worse disease activity, QOL, and work productivity measures. This study highlights the heterogeneity of PsA and the importance of assessing all PsA domains for optimizing disease management.
