Pilot Open-Label Trial of Resistant Potato Starch in Patients With Cirrhosis and Overt Hepatic Encephalopathy

Conditions

Hepatic Encephalopathy Cirrhosis Resistant Potato Starch

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This research is studying how a food product (resistant potato starch) which is a dietary supplement made from potato starch affects the gut bacteria of people with cirrhosis and hepatic encephalopathy. The researchers in this study want to understand how potato starch works in the subject's body and how the body will react to it. Along with taking the study product participants health-related information and stool will be collected for this research study.
