NCT04159727

Brief Summary

Inflammatory bowel diseases (IBD) and Parkinson disease (PD) are complex and multifactorial pathologies. Gut microbiota seems to play an active role. Indeed the digestive microbiota of patients with IBD or PD exhibits different compositions compared with asymptomatic subjects. Bacterial translocation from gut to blood has been reported.
