Rifaximin vs Placebo for the Prevention of Encephalopathy in Patients Treated by TIPS

Phase 3
Completed
Conditions
Cirrhosis
Interventions
Drug: placebo
Registration Number
NCT02016196
Lead Sponsor
University Hospital, Toulouse
Brief Summary

TIPS has been used for 20 years, as a means of reducing portal pressure in patients with cirrhosis and portal hypertension related complications. TIPS proved more effective than alternative treatments in controlling or preventing variceal bleeding and refractory ascites. The main drawback of the TIPS procedure is progressive overt hepatic encephalopathy (OHE). Three risk factors for post-TIPS OHE have been identified: age over 65 years, history of previous episodes of OHE, and Child-Pugh score equal to or over 10. However, the incidence of post-TIPS OHE in patients fulfilling these criteria remains close to 35 %.

Detailed Description

TIPS has been used for 20 years, as a means of reducing portal pressure in patients with cirrhosis and portal hypertension related complications. TIPS proved more effective than alternative treatments in controlling or preventing variceal bleeding and refractory ascites. The main drawback of the TIPS procedure is progressive overt hepatic encephalopathy (OHE). Three risk factors for post-TIPS OHE have been identified: age over 65 years, history of previous episodes of OHE, and Child-Pugh score equal to or over 10. However, the incidence of post-TIPS OHE in patients fulfilling these criteria remains close to 35 %. Furthermore, the pathogenesis of HE in general but also in patients treated by TIPS is still not well understood. Therefore, there is a real challenge in discovering new molecular mechanisms involved in pathogenesis of OHE as well as new treatment to better prevent the risk of OHE in patients treated by TIPS. Observational and experimental studies suggest a microbiota's role in the mechanism of OHE and recently a non absorbable antibiotic has proven to reduce the risk of recurrence of OHE. However, the effect of this drug for the prevention of a first episode of OHE in patients treated by TIPS is not known. In addition, the mechanisms of the beneficial effect of rifaximin remain poorly understood.
