Fecal Microbiota Transplantation by Oral Capsules for Hepatic Encephalopathy Treatment

Summary

This interventional study aims to evaluate the safety and efficacy of oral capsule fecal microbiota transplantation (FMT) for treating hepatic encephalopathy refractory to conventional rifaximin and lactulose therapy in patients with liver cirrhosis. Patients diagnosed with hepatic encephalopathy refractory to rifaximin and lactulose therapy will be randomized into three groups. While continuing conventional therapy, the first group receives FMT via colonoscopy and oral capsule administration, the second group receives only oral capsule administration, and the third group serves as a control, receiving only conventional therapy. The aims of the study are: To evaluate the efficacy and safety of FMT by oral capsules in cirrhotic patients with hepatic encephalopathy refractory to standard therapy. To evaluate changes in the gut microbiota composition and in the intestinal and systemic inflammatory condition occurring after FMT and if they can be associated with clinical improvement. To evaluate metabolic modifications occurring after FMT and if they can be associated with clinical improvement.
