What Researchers Did
Researchers conducted a pilot study where patients with severe ulcerative colitis, who hadn't responded to other treatments, received 10 or 20 daily hyperbaric oxygen therapy sessions at 2.4 atmospheres absolute for 120 minutes each.
What They Found
In this pilot study of 16 patients, 25% (2 out of 8) of those receiving 10 HBOT sessions and 50% (4 out of 8) of those receiving 20 sessions achieved a combined clinical and endoscopic response by week 12. Patients who responded clinically also showed increased blood flow in their bowels, with a peak enhancement of 12.1 dB, while non-responders saw a decline of 5.4 dB. The therapy was well tolerated, with no serious side effects or discontinuations.
What This Means for Canadian Patients
For Canadian patients living with ulcerative colitis that hasn't responded to standard treatments, this study suggests that hyperbaric oxygen therapy could be a safe and effective additional treatment. It may help improve symptoms and increase blood flow to the bowel, potentially offering a new option for managing this challenging condition.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This was a small, open-label pilot study, meaning the findings need to be confirmed in larger, more controlled trials.
