Ankylosing Spondylitis Clinical Trial
This study aims to compare biological communities in stool samples obtained from age, diet
and BMI-matched subjects in five study groups: subjects with ankylosing spondylitis (AS)
never treated with tumor necrosing factor (TNF) inhibitors, subjects with ankylosing
spondylitis previously or currently treated with TNF inhibitors, subjects with
non-radiographic axial spondyloarthritis (nrSpA) never treated with tumor necrosing factor
(TNF) inhibitors, subjects with non-radiographic axial spondyloarthritis previously or
currently treated with TNF inhibitors and healthy participants.
The differences in fecal microbiota composition will be explored using shotgun metagenomic
sequencing through the University of Washington. The investigators predict that this study
will confirm a significant difference between the fecal microbiota composition (FMC) of both
AS and nrSpA patients and controls.
