Prologue: Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2024 Annual Meeting

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2024 annual meeting was held from July 11 to July 13, 2024, in Seattle, Washington, USA, and was attended by 256 rheumatologists, dermatologists, trainees, patient research partners, patient organization representatives, industry partners, and others. The meeting featured several workshops on various topics including epidemiology, new educational initiatives, use of artificial intelligence for both education and clinical management of disease, use of magnetic resonance imaging in the diagnosis and management of psoriatic disease (PsD), and many more. Young-GRAPPA held a workshop and business meeting about their projects, and many of the young GRAPPiAns contributed as coauthors of the articles in this supplement. Debates focused on whether clinical enthesitis indices reflect true enthesitis and whether they should be discontinued, and whether musculoskeletal symptoms in PsD should be managed by dermatologists or rheumatologists. Here we provide an overview of the features of the GRAPPA 2024 annual meeting and introduce the manuscripts published together in this supplement as a meeting report.
