A Pilot Study: Micro and NanoPlastics in Association With Crohn's Disease
Integrated Multi-phase Investigation of Role of Micro and NanoPlastics in Association With Crohn's Disease: Targeting Microbiome, Immunity, and Barrier Dysfunction: A Pilot Study
Source: ClinicalTrials.gov · Last updated 5 Jun 2026
Brief summary (registry, in English)
Micro and nanoplastics (MNPs) are environmental contaminants found in food and water. Recent evidence suggests these particles may be linked to intestinal inflammation and changes in gut bacteria, which are key features of Crohn's Disease (CD). This study aims to investigate if patients with Crohn's Disease have a reduced ability to clear these plastic particles and how this affects their immune system and intestinal health.
