As in previous years, GRAPPA members held a symposium for trainees to discuss their research in psoriatic disease with experts in the field. Other subjects featured during the annual meeting included a discussion of the history, clinical features, controversies, and immunogenetics of juvenile psoriatic arthritis; updates from working groups in Outcome Measures in Rheumatology and International Dermatology Outcome Measures; a discussion of the benefits and challenges of setting up a longitudinal psoriatic arthritis (PsA) database; 3 separate discussions of the effects of the microbiome on skin and joints in psoriasis and PsA; a discussion of options for assessing joints and entheses in PsA by ultrasonography and magnetic resonance imaging; an update on GRAPPA’s research and educational projects; a discussion of patient centricity, including the incorporation of patient research partners (PRP) into psoriasis and PsA research and educational efforts, from GRAPPA’s PRP; and a discussion of the GRAPPA-Collaborative Research Network’s inaugural meeting. In this prologue, we introduce the papers that summarize that meeting. ER -
