Gut leak link to Sjögren's Flare-Ups under microscope
NCT ID NCT04462601
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether changes in gut bacteria can affect Sjögren's syndrome, an autoimmune disease causing dry eyes, dry mouth, and fatigue. Researchers will measure blood markers of gut leakage in 50 adults with Sjögren's to see if these markers change when disease activity changes. The goal is to better understand the connection between gut health and autoimmune symptoms.
