Is the Human Microbiome Altered in Patients With Axial Spondyloarthritis?
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.

Studiebefolkning
At least 50 subjects, male and female, aged 18 or older, will be recruited to the study and assigned to one of five groups:
- Ten TNF blocker-naïve ankylosing spondylitis patients
- Ten TNF blocker-exposed ankylosing spondylitis patients
- Ten TNF blocker-naïve nrSpA patietns
- Ten TNF blocker-exposed nrSpA patients
- Ten healthy age, diet and BMI-matched controls Inclusion and exclusion criteria will vary by study group. It is anticipated that the TNF-blocker naïve groups will be the most difficult to recruit, so these groups will serve as the baseline for age and diet matching for the other two groups. Up to seventy (70) additional TNF-treated axial SpA and healthy subjects may be asked to complete the dietary questionnaire, but will not provide stool samples unless age, diet and BMI-matched with a TNF-blocker-naïve axial SpA subject.
