Analysis of Intestinal Microbiota as a Predictor of Response to Treatment of Spondyloarthritis With Biotherapy
Recruiting now · Not applicable
Conditions studied: Spondyloarthritis
In brief
Spondyloarthritis (SpA) is a group of inflammatory rheumatic disorders that mainly manifested by inflammatory pain of the spine, pelvis and sometimes limbs. Classically, SpA has been classified into several subtypes, such as ankylosing spondylitis (AS), psoriatic arthritis (PsA), inflammatory bowel disease (IBD)-associated. Several studies have shown specific changes in the gut microbiota during SpA. A recent, uncontrolled study suggested that the therapeutic response to anti-TNFα (Tumor Necrosis Factor) therapy could be predicted by analysis of the gut microbiota. The purpose of the study MEDIBIOTE 3 is to confirm that in SpA, the composition of the intestinal microbiota at the initiation of treatment is predictive of the response to treatment with biotherapy (anti-TNFα / anti-IL17).
