Abstract

Objectives: To determine the individual impact of key manifestations of psoriatic arthritis (PsA) on quality of life (QoL), physical function, and work disability. Methods: Data from the Adelphi 2018 PsA Disease-Specific Programme, a multinational, cross-sectional study of PsA patients, were used. PsA manifestations included peripheral arthritis (number of joints affected), psoriasis (body surface area [BSA]), axial involvement (inflammatory back pain [IBP] and sacroiliitis) enthesitis, and dactylitis. General, and disease-specific QoL, physical function, and work disability were measured with EQ-5D-5L, PsAID-12, HAQ-DI, and WPAI, respectively. Multivariate regression adjusting for potential confounders evaluated the independent effect of PsA manifestations on each outcome. Results: Among the 2222 PsA patients analysed, 77.0% had active psoriasis and 64.4% had peripheral arthritis; 5.9%, 6.8%, 10.2%, and 3.6% had enthesitis, dactylitis, IBP, or sacroiliitis, respectively. Mean EQ VAS scores were significantly poorer in patients with vs. without enthesitis (59.9 vs. 75.6), dactylitis (63.6 vs. 75.4), and with greater peripheral joint involvement (none: 82.5; 1–2 affected joints: 74.1; 3–6 joints: 74.2; > 6 joints: 65.0). Significantly worse mean PsAID-12 scores were associated with vs. without enthesitis (4.39 vs. 2.34) or dactylitis (4.30 vs. 2.32), and with greater peripheral joint involvement (none: 1.21; 1–2 joints: 2.36; 3–6 joints: 2.74; > 6 joints: 3.92), and BSA (none: 1.49; > 3–10%: 2.96; > 10%: 3.43). Similar patterns were observed with HAQ-DI and WPAI scores. Conclusion: Most PsA manifestations were independently associated with worse general, and PsA-specific QoL, physical function, and work disability, highlighting the need for treatments targeting the full spectrum of PsA symptoms to lower the burden of disease.
