Shared Biorepository for the Investigation of Inflammatory Arthritis at Mayo Clinic and University of Massachusetts


About this study

The purpose of this study is to establish a comparator cohort of patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and other spondyloarthropathies. We will collect demographic information, historical information about diagnosis and past treatment, and clinical, radiographic, and laboratory data on each patient using standardized data collection forms.  We will also collect blood and synovial tissue samples from each patient.  This will provide data and material for clinical and translational research to address questions related to the fundamental differences between the spondyloarthropathies and inflammatory arthritis relating to the response of bone to chronic inflammation.  We intend to enroll sequential patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and other spondyloarthropathies who present to the Rheumatology Division at Mayo Clinic Rochester. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
