Abstract

OBJECTIVE: Real-world studies assessing treatment response by psoriatic arthritis (PsA) domains are limited. This study aimed to describe the patient characteristics, frequency and combinations of disease domains, disease activity, and patient-reported outcomes (PROs) by PsA domains in patients who initiated treatment with a tumor necrosis factor inhibitor (TNFi) or interleukin-17 inhibitor (IL-17i).

METHODS: Adults with PsA who initiated treatment with a TNFi or an IL-17i between January 2013 and January 2021 and had a 6 (±3)-month follow-up were included. The prevalence of PsA domains, the most common domain combinations, treatment persistence, and unadjusted change in disease activity and PROs from baseline to 6 months for each PsA domain were summarized descriptively.

RESULTS: Of the 1005 eligible patients, 63% were receiving TNFi and 37% were receiving IL-17i. Forty percent of TNFi and 14% of IL-17i initiators received these treatments as first-line therapy. Peripheral arthritis and skin disease were the most common PsA domains identified in 86% and 82% of patients, respectively, and the triad of peripheral arthritis, skin disease, and nail psoriasis was the most common domain combination observed in 14% of patients. More than two thirds (68%) of patients remained on therapy at 6 months' follow-up. Improvements in disease activity and PROs were observed across all PsA domains in those receiving TNFi or IL-17i.

CONCLUSION: This real-world analysis highlights the heterogeneity in domain presentation; therefore, assessing all PsA domains is important for optimal disease management. Improvements in outcomes across all PsA domains demonstrate the effectiveness of TNFi and IL-17i in diverse patient groups exhibiting different phenotypes of PsA.
