PsA gets a honorable mention in this article as possibly being caused by disruptions in the micro biome. I was on several rounds of different antibiotics last year, with the last round ending just before the arthritis started. I also had a major GI infection and several URIs that year. I wonder if my illness would have been more mild, or started later, or not been triggered at all if I hadn't taken so many rounds of antibiotics or had those infections, or both?
Has anyone else seen more articles/research on this subject?
