Core tip: Currently, inflammation appears to play a critical role in the pathogenesis of hepatic encephalopathy (HE) and is gradually being considered a critical therapeutic target for HE in patients with liver cirrhosis. Current therapies for HE, including lactulose, rifaximin, probiotics and the molecular adsorbent recirculating system, have been found to improve clinical manifestations and prevent the progression of HE by ameliorating inflammation in cirrhotic patients. This review will provide an overview of the inflammatory pathogenesis of HE, focusing on the recent findings on its therapeutic manipulation.
