What Researchers Did
Brazilian researchers tested whether HBOT could reduce intestinal inflammation in mice with chemically induced colitis designed to mimic Crohn's disease.
What They Found
Mice treated with HBOT had significantly better clinical scores and less bowel damage on microscopy than untreated colitis mice. HBOT increased the activity of antioxidant enzymes (superoxide dismutase and glutathione peroxidase), reduced pro-inflammatory molecules (IFN-γ, IL-12, IL-17, TNF-α), and increased anti-inflammatory molecules (IL-4 and IL-10).
Canadian Relevance
No direct Canadian connection identified. Inflammatory bowel disease is not an OHIP-covered indication for HBOT in Ontario.
Study Limitations
This was a mouse model of chemically induced colitis, which does not fully replicate the complexity and chronicity of human Crohn's disease.
