Key clinical point: Difficult-to-treat (D2T) psoriatic arthritis (PsA), a condition characterized by the failure of ≥2 targeted synthetic or biologic disease-modifying antirheumatic drugs (ts/bDMARD), is associated with a higher prevalence of axial involvement, structural damage, and treatment discontinuation.
Major finding: Peripheral structural damage (odds ratio [OR] 2.57; P = .020), axial involvement (OR 2.37; P = .035), and the discontinuation of bDMARD due to poor dermatological control (OR 2.99; P = .008) were more prevalent in patients with D2T PsA vs non-D2T PsA.
Study details: Findings are from a retrospective cohort study including 150 patients with PsA who initiated treatment with ts/bDMARD and were followed up for ≥2 years, of whom 49 patients had D2T PsA.
Disclosures: This study did not receive any funding. Three authors declared receiving honorary fees or research grants or serving as advisory board members for various sources.
