Key clinical point: This real-world study showed that almost 1 in 6 patients with psoriatic arthritis (PsA) had potentially difficult-to-treat (D2T) disease, which was associated with extensive psoriasis, higher body mass index (BMI), and a history of inflammatory bowel disease (IBD).
Major finding: Of 467 patients, 16.5% had D2T PsA. Compared to non-D2T patients, those with D2T disease were more likely to have extensive psoriasis at diagnosis (odds ratio [OR] 5.05; P < .0001), higher BMI (OR 1.07; P = .023), and a history of IBD (OR 1.22; P = .026).
Study details: This study analyzed 467 patients with PsA from a Greek registry who had ≥6-months of disease duration, progressed on disease modifying anti-rheumatic drugs with different mechanisms of actions, and had disease activity index for PsA > 14 or were not at minimal disease activity .
Disclosures: The registry was funded by the Greek (Hellenic) Rheumatology Society. The authors declared no conflicts of interest.
