Key clinical point: Fluorescence-optical imaging (FOI) successfully detected the early signs of musculoskeletal inflammation in hands and predicted transition from psoriasis to psoriatic arthritis (PsA) at initial stages in patients with psoriasis at risk for PsA.
Major finding: PsA diagnosis was confirmed by clinical evaluations (CE) in 50% of patients with psoriasis at risk for PsA and an additional 30% of patients who were positive on FOI. Compared with previously published annual incidence rates, the incidence rate of PsA was higher among patients positive on FOI but negative on CE (11.8%).
Study details: This was an investigator-initiated prospective two-part observational cohort study including 389 patients with plaque psoriasis who were at risk for PsA.
Disclosures: This study was sponsored by Fraunhofer ITMP and supported by a research grant from Pfizer Germany. Five authors declared being supported by Fraunhofer ITMP. Several authors reported ties with various sources, including Pfizer. GR Burmester reported being on the editorial board of RMD Open.
