Hepatic Encephalopathy

Abstract

One of the major trends we predict for the future is a totally different focus for hepatic encephalopathy (HE) treatment. Formerly, all trials of new therapeutic agents for the treatment of HE were performed in patients with overt HE. Since most of these patients had advanced liver disease and at times multiple precipitating events for episodes of HE, it was not possible to perform randomized controlled clinical trials in these patients. This may explain why no new drug was approved for the treatment of HE in the past 30 years. These days minimal or covert HE can be reliably detected and quantified. It is generally seen earlier in the course of liver disease when precipitating factors are relatively rare. Accordingly, new therapeutic agents will be tested for efficacy in this population of HE patients.
