Gut Instinct: Ankylosing Spondylitis & the Microbiome

Jason Liebowitz, MD, FACR  |  Issue: March 2020  |  October 3, 2019

Microbiome Sequencing
In the modern world of commercially available genetic sequencing, Dr. Scher stated it is not a far-fetched idea that, one day, microbiome sequencing will become available to patients and require interpretation by a host of healthcare providers, including those in the field of rheumatology. With the burgeoning understanding of the role microbiota may play in the pathogenesis of ankylosing spondylitis, it will be incumbent upon rheumatologists to learn more about this topic to help guide patients.

As many practicing rheumatologists know already, patients are eager to understand the role diet and the environment may play in inflammatory pathways and the development of autoimmune disease, and the microbiome is a part of this larger picture. Even though it may be many years from now before physicians can give specific recommendations on how to change diet, avoid antimicrobials, repopulate gut flora with probiotics and other interventions, and ultimately select personalized therapy for patients with ankylosing spondylitis and other conditions in the category of spondyloarthritis, it is more than a gut feeling that this area of research will continue to grow more and more important in the years to come.

    The mechanistic link between human leukocyte antigen B27 (HLA-B27) and ankylosing spondylitis (AS) is one of the great enigmas in rheumatology. The introduction of biological therapies that target tumor necrosis factor (TNF) or the interleukin (IL) 23/IL-17A axis has had a major impact on the quality of life for many patients with AS, and one…

    Understanding how human leukocyte antigen (HLA) class I molecule B27 promotes spondyloarthritis has intrigued researchers for four decades. Although the association between the single gene variant HLA-B27—specifically some of its subtypes—with ankylosing spondylitis (AS) is particularly strong, how HLA-B27 directly influences disease development has not yet been clearly explained, although hypotheses continue to be generated….

    First Appearances I watched the old man, his back painfully bent, shuffle toward the scale. A blocky rigidity draped over him. His feet seemed stuck to the floor. His head hung heavily over his chest. Observing him from the end of the hallway, instead of a face, I saw only a mound of shaggy, matted…
