Understanding spondyloarthritis over time
Part of Bones, joints & muscles, Immune system & allergy, Skin clinical trials.
This study follows people with spondyloarthritis (an inflammatory arthritis that often affects the spine and joints) and their family members over time to better understand how the disease develops and progresses. It also includes a research stool sample test to learn about gut bacteria.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have known or suspected spondyloarthritis (SpA), OR be a family member of someone with SpA.
- If you are a healthy volunteer (control), you need to be at least 6 years old and not pregnant.
- Children as young as 2 can enroll, but those under 6 may need special evaluation.
- Pregnant people with SpA may join but won't be asked to have an MRI or biopsies.
- If you want to join the extra stool (fecal) study, you must already be in another NIH natural history study.

This study follows people with systemic juvenile idiopathic arthritis (sJIA), adult-onset Still’s disease (AOSD), and similar conditions to learn how the illness works over time. It also collects blood and family information to study genetics and explain what causes flare-ups, which may help future care.
This study follows people who were recently diagnosed with spondyloarthritis (a type of arthritis) to see how their symptoms change over time. It helps doctors understand the early stages of the disease better.
This study enrolls people who have recently been diagnosed with certain inflammatory conditions affecting the spine, joints, or the eye. Researchers are looking to better understand how these illnesses start and how they may be linked, which could help guide future care.
This study looks at how a body signal called IL-23 may drive inflammation in spondyloarthritis (including joints) using samples from your care. It may help researchers identify which body cells and targets are involved, and how treatments could work better for active disease.
This trial is for people with ankylosing spondylitis (a type of arthritis that affects the spine) who are otherwise healthy. It may test a treatment to see if it helps control symptoms, whether your disease is active or stable.
This study follows patients with spondyloarthritis over time to better understand the condition. It collects information from hospital visits and may help improve care for people with this type of arthritis.
