Gut check: your microbiome may predict arthritis drug success

This study looks at whether the types of bacteria in your gut can predict how well you will respond to biologic drugs for spondyloarthritis, a group of inflammatory conditions affecting the spine and joints. Researchers will compare the gut bacteria of 80 people starting biotherapy and see if certain bacteria patterns are linked to better treatment outcomes. The goal is to help doctors choose the right treatment from the start, avoiding trial-and-error.
