Key clinical point: Patients with psoriatic arthritis (PsA) who did or did not respond to treatment with tumor necrosis factor alpha inhibitor (TNFi) and interleukin-17A inhibitor (IL-17Ai) showed different profiles of pro- and anti- inflammatory cytokines.
Major finding: At 4 months of follow up, a significant decrease in IL-6 (P = .032) and an increase in IL-10 (P = .010) was seen in patients achieving ≥ 50% improvement in Disease Activity in PsA (DAPSA50) response with TNFi treatment. IL-17Ai treatment showed decrease in IL-1α and IL-27 levels in DAPSA50 responders and increase in IL-17A in both DAPSA 50 responders and non-responders (all P < .05).
Study details: This study included 68 patients with PsA who were initiated with TNFi (n = 29), IL-17Ai (n = 19), or methotrexate (n = 20) treatment and were followed for 4 months.
Disclosure: This study was supported by Eli Lilly and Co., the Danish Rheumatism Association, and others. Two authors declared receiving research funding, speaker fees, and other ties with various sources, including Eli Lilly and the Danish Rheumatism Association. Two authors declared no conflicts of interest.
