Key clinical point: Patients with psoriasis and concurrent psoriatic arthritis (PsA) reported more extensive skin disease than patients with only psoriasis, with psoriasis severity being significantly associated with higher odds of concurrent PsA.
Major finding: Body surface area scores were significantly higher in patients with psoriasis and concurrent PsA vs patients with only psoriasis (mean difference 5.31; 95% CI 1.78-8.83), with severe psoriasis being a significant predictor of concurrent PsA ( odds ratio 3.34; P < .001 ).
Study details: This was a meta-analysis of 29 studies including adult patients with psoriasis with or without concurrent PsA or adult patients with psoriasis who developed PsA.
Disclosures: This study did not receive any funding. JM Laar declared receiving research grants and honoraria from several sources.
