History

Originally inspired by the Assessment in Ankylosing Spondylitis Working Group (ASAS), GRAPPA was formed in 2003. GRAPPA has pulled together many different groups, including preeminent researchers and thought-leaders in psoriatic arthritis (PsA) and psoriasis (PsO). In 2015 a team of Patient Research Partners was added to round out our perspective.  The idea was to form a consortium of rheumatologists, dermatologists, radiologists, epidemiologists, patient representatives and others who would like to contribute to the field of PsA. At the inaugural meeting in 2003, a consensus exercise started the group toward prioritizing domains of inquiry in PsA and PsO. Subsequent annual meetings have focused on identifying and initiating research projects, advancing standardized criteria for psoriatic arthritis registries, and developing treatment guidelines for PsA. GRAPPA is a 501(c)3 nonprofit organization with offices in Seattle, WA and members from around the world.
 
Today, more than 800 thought-leaders participate in GRAPPA including rheumatologists, dermatologists, radiologists, geneticists, methodologists, epidemiologists, patient research partners, and biopharmaceutical industry representatives. Approximately 75 percent of our members live and work outside North America; creating a truly international effort.

GRAPPA's Mission:

GRAPPA (Group for Research and Assessment of Psoriasis and Psoriatic Arthritis) is organized exclusively for non-profit, educational, and scientific purposes, specifically to facilitate sharing of information related to psoriasis and psoriatic arthritis, networking among different medical disciplines that see psoriasis and psoriatic arthritis patients, and to enhance research, diagnosis and treatment of psoriasis and psoriatic arthritis.
