Key clinical point: Patients with psoriasis were more likely to have a delayed onset of psoriatic arthritis (PsA) if they were diagnosed with psoriasis at a younger age or suffered from severe psoriasis.
Major finding: The median time from psoriasis diagnosis to the incidence of PsA was 35.5 months with age at psoriasis onset (odds ratio [OR] per 10-year decrease 1.63; 95% CI 1.26-2.11) and its severity (OR for severe vs. mild 3.65; 95% CI 1.18-11.32) being associated with having a psoriasis diagnosis >1 year prior to incident PsA.
Study details: Findings are from a retrospective nested case-control study including 158 patients with incident PsA, of which 41% had concurrent psoriasis and 59% patients had onset of psoriasis before PsA.
Disclosures: This study was funded by the Rochester Epidemiology Project supported by National Institute on Aging, National Center for Advancing Translational Sciences, and others.
