Full Study Name

Spondyloarthritis Clinical Repository (IRB no. 40791)


The purpose of this study is to increase knowledge about spondyloarthropathies and their outcomes, as well as to better understand the causes and improve treatment and care. Spondyloarthropathies are a group of related joint diseases that share common clinical features, generally involving the sacroiliac joints (where the low back connects to the pelvis) and/or areas around joints where ligaments and tendons attach to bone. This group of diseases includes ankylosing spondylitis, psoriatic arthritis and reactive arthritis, among others.

The study will collect information to create a clinical repository, which will make ongoing research in spondyloarthritis possible at Cedars-Sinai. A repository is similar to a bank or storehouse. Participants will provide clinical information, blood and stool, which can be used in current studies and/or future research. DNA and RNA will also be collected.
