Summary

What Researchers Did

A clinician reported on a single 60-year-old woman with Chronic Inflammatory Response Syndrome (CIRS), a complex illness linked to mold toxin exposure, who underwent 40 low-pressure HBOT sessions (shallow dive) over 10 weeks.

What They Found

After 40 HBOT sessions, all 22 of the patient's symptoms resolved. Her visual contrast sensitivity score improved from 68% to 93% (normal is above 70%). Inflammatory biomarkers including TGF-β1 and MMP-9 dropped significantly. These improvements were noted incidentally, the HBOT was not originally prescribed for CIRS.

Canadian Relevance

No direct Canadian connection identified.

Study Limitations

This is a single-patient case report with no control condition, no blinding, and a pre/post comparison using different commercial labs, which limits the reliability of biomarker comparisons.
