The Role of Bacterial Overgrowth and Delayed Intestinal Transit in Hepatic Encephalopathy.

Stopped early · Not applicable

Conditions studied: Hepatic Encephalopathy

In brief

This is a prospective study designed to examine the role of bacterial overgrowth and delayed intestinal transit and the effect of Rifaximin with hepatic encephalopathy (HE). This study is divided into Phase A and Phase B. The purpose of Phase A is to test patients with cirrhosis to determine if they have bacterial overgrowth which may lead to slow intestinal transit and hepatic encephalopathy. The purpose of Phase B is to investigate whether the improvement found in patients with hepatic encephalopathy taking Rifaximin is also related to decreased bacterial overgrowth. Subjects' mental capacity will be assessed at each visit via interview, brief mental status, questionnaires and psychometric evaluation. Any subject who appears to have lost capacity to continue participation, as evidenced by HE grade 2 or higher, a lack of attentiveness, concentration, or understanding of evaluation, will be discontinued from the study. Female subjects of childbearing potential will be asked to comply with the use of contraception during the Phase B study period as well as throughout the time they remain on study drug.
