Biomarkers in Psoriasis and Psoriatic Arthritis: Where Are We Now?

Abstract

At the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual conference and trainee symposium, the status of psoriatic disease (PsD) biomarkers was discussed in a workshop. The significant heterogeneity of PsD causes disease management to be very challenging, but biomarkers can prove helpful in disease diagnosis, stratification, and precision medicine. Although a few potential biomarkers have been discovered, none have been fully validated. Recent studies have used omic technologies that show promise but need further verification and validation. Many challenges remain, but the anticipated results of studies being conducted by recently established large consortia may lead to the identification of clinically actionable biomarkers.
