What this trial studies

This clinical trial investigates the effects of hyperbaric oxygen therapy (HBOT) on patients with ulcerative colitis (UC) who are hospitalized for acute moderate to severe flares. The study aims to confirm previous findings that HBOT can improve remission rates and reduce the need for more aggressive treatments like biologics or colectomy. Participants will receive either HBOT or a sham treatment, and the trial will also explore the immune-microbe mechanisms that may explain the treatment's effectiveness. The goal is to provide a larger dataset to validate the benefits of HBOT in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-85 with known or newly diagnosed ulcerative colitis requiring hospitalization for an acute flare.

Not a fit: Patients who have previously received hyperbaric oxygen therapy or those with severe complications requiring urgent surgical intervention may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve remission rates for patients with ulcerative colitis during acute flares.

How similar studies have performed: Previous smaller trials have shown promising results for hyperbaric oxygen therapy in ulcerative colitis, suggesting potential for success in this larger study.
