At the 2009 annual meeting of GRAPPA (Group for Assessment of Psoriasis and Psoriatic Arthritis) in Stockholm, Sweden, 15 fellows involved in research in psoriatic disease were invited to present their work at a Trainees Symposium, which was also attended by members of the GRAPPA Faculty Committee. All of the fellows held poster sessions of their work and 4 of them gave oral presentations, including identification of soluble biomarkers for psoriatic arthritis (PsA), validation of minimal disease activity criteria for PsA, disease progression using the modified Sharp score, and discussion of a new composite disease activity score for PsA. Senior GRAPPA members also instructed the fellows on other composite scoring methods and on training videos and other GRAPPA projects to date. All of the posters and presentations from the Trainees Symposium are summarized herein.
