The following is an announcement from SAA about a third party research opportunity. SAA is not affiliated with this study,


Researchers at the Spondyloarthritis Research Program at University of California, San Francisco (UCSF) are looking to identify and compare the gut bacteria of children of ankylosing spondylitis parents.

The study aims to identify gut bacteria that may lead to the development of the disease. The study is funded by a grant from the Spondylitis Association of America, and compensation (of $50) is offered for your time.

You may be eligible to participate if:

  • • Are an adult diagnosed with Ankylosing Spondylitis (meeting modified NY criteria), and are HLA B27 positive
  • • Have biological children between the ages of 5-19 years old (with or without ankylos-ing spondylitis)
  • • Are *not* currently taking antibiotics or sulfasalazin

Study Visit Details:

The study requires one visit to UCSF that lasts approximately 1 hour. During the visit, we will ask questions regarding you and your children’s medical history and your chil-dren will be examined by a Pediatric-Rheumatologist. We will collect saliva samples in clinic. You will be provided stool kits to take home and we will provide you with labels to have stool specimens shipped at our expense.

Study Location:

University of California, San Francisco
Arthritis and Rheumatology Clinic
400 Parnassus Avenue
Floor B1, Suite A095
San Francisco, CA 94541


You will be given a check for $50 upon receipt of each stool specimen.
