What this trial studies

This interventional study evaluates the safety and efficacy of fecal microbiota transplantation (FMT) delivered through oral capsules for patients with hepatic encephalopathy that does not respond to standard treatments like rifaximin and lactulose. Participants with liver cirrhosis will be randomized into three groups: one receiving FMT via colonoscopy and oral capsules, another receiving only oral capsules, and a control group continuing conventional therapy. The study aims to assess changes in gut microbiota composition and inflammation, correlating these changes with clinical improvements in patients.

Who should consider this trial

Good fit: Ideal candidates include patients with liver cirrhosis and hepatic encephalopathy grade >1 who have not responded to conventional therapies.

Not a fit: Patients with contraindications to fecal microbiota transplantation or other causes of encephalopathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new treatment option for patients suffering from refractory hepatic encephalopathy.

How similar studies have performed: While fecal microbiota transplantation has shown promise in other conditions, this specific approach for hepatic encephalopathy is novel and has not been extensively tested.
