Hyperbaric oxygen effective adjunct for reducing ulcerative colitis flares: Study

"Initially, all patients received 3 days of hyperbaric oxygen at 2.4 atmospheres in addition to intravenous steroids. Day 3 responders were randomized to receive a total of 5 days vs 3 days of hyperbaric oxygen", explained Dulai.

Also, UC patients hospitalized for moderate-severe flares were blocked randomized to steroids + daily HBOT or steroids + daily sham hyperbaric air. The authors evaluated the primary outcome as the clinical remission rate at study day 5.

The study revealed the following findings-

a. Day 3 response was achieved in 55% (n = 11/20), with significant reductions in stool frequency, rectal bleeding and CRP.

b. A more significant reduction in disease activity was observed with 5 days vs 3 days of hyperbaric oxygen.

c. Day 3 hyperbaric oxygen responders were less likely to require re-hospitalization vs non‐responders.

d. No treatment‐related adverse events were observed.

Therefore, the researchers further concluded that "Hyperbaric oxygen appears to be effective for optimizing response to intravenous steroids in UC patients hospitalized for acute flares, with low rates of re-hospitalization or colectomy at 3 months". Also, an optimal clinical response is achieved with 5 days of hyperbaric oxygen. A larger phase 3 trials are needed to confirm the efficacy and obtain labeled approval.For further reference log on to: https://doi.org/10.1111/apt.15984
