Key clinical point: Patients with psoriatic arthritis (PsA) who were disease-modifying antirheumatic drug (DMARD)-naive or non-responders to previous conventional synthetic DMARD treatment (DMARD-failure) showed similar inflammation and structural damage on imaging.
Major finding: After adjusting for patient characteristics, structural imaging parameters including Achilles tendon structural damage and Joint Space Narrowing scores (both P > .6) were similar in DMARD-naive and DMARD-failure patients. Additionally, inflammatory imaging parameters ( P > .2) showed no significant differences between the two groups, indicating that failing a DMARD was not associated with worsened imaging outcomes.
Study details: This cross-sectional study evaluated 80 patients with PsA from TOFA-PREDICT trial who were either DMARD-naive (n = 40) or DMARD non-responders (n = 40).
Disclosures: This study was supported by Pfizer. The collaboration project was co-funded by the public-private partnerships allowance by Health~Holland, Top Sector Life Sciences & Health. Six authors declared receiving research grants, consulting fees, and support from various sources, including Pfizer. Other authors declared no conflicts of interest.
