Brief Summary

This is a pilot study designed to evaluate the efficacy and safety of nifuroxazide in the treatment of hepatic encephalopathy in patients with grade II-III hepatic encephalopathy

Detailed Description

Hepatic Encephalopathy (HE) is a central nervous system dysfunction caused by liver insufficiency and/or portosystemic shunting, manifesting as a wide spectrum of neurological or psychiatric abnormalities characterized by alteration of cognitive and motor function.

The pathogenesis of hepatic encephalopathy is believed to be due to increased nitrogenous substances, primarily ammonia, in the blood. The treatment goal is to reduce nitrogen load from the GI tract and to improve central nervous system (CNS) status.

Treatment options include lactulose administered orally and non-absorbable antibiotics.

Lactulose is nonabsorbable disaccharides that is currently used as first line agents for the treatment of HE. Its action is thought to be due to Colonic metabolism of lactulose to lactic acid results in acidification of the gut lumen. This favors conversion of ammonium (NH4) to ammonia (NH3) and the passage of ammonia from tissues into the lumen. Gut acidification inhibits ammoniagenic coliform bacteria, leading to increased levels of nonammoniagenic lactobacilli. Lactulose also works as a cathartic, reducing colonic bacterial load.

Nifuroxazide is an oral broad-spectrum nitrofuran antibiotic that is commonly used as an intestinal anti-infective agent. It is active against the majority of intestinal bacteria: Gram-positive (Staphylococcus family) and Gram-negative (Enterobacteriaceae family: Escherichia, Citrobacter, Enterobacter, Klebsiella, Salmonella, Shigella, Yersinia) and is therefore expected to decrease ammonia production and to reverse the symptoms of HE.
