| 1 | Dietary approach and gut microbiota modulation for chronic hepatic encephalopathy in cirrhosis显示文摘Hepatic encephalopathy(HE)is a common and serious neuropsychiatric complication of cirrhosis,acute liver failure,and porto-systemic shunting.HE largely contributes to the morbidity of patients with liver disease,severely affecting the quality of life of both patients and their relatives and being associated with poor prognosis.Its presentation is largely variable,manifesting with a broad spectrum of cognitive abnormalities ranging from subtle cognitive impairment to coma.The pathogenesis of HE is complex and has historically been linked with hyperammonemia.However,in the last years,it has become evident that the interplay of multiple actors,such as intestinal dysbiosis,gut hyperpermeability,and neuroinflammation,is of crucial importance in its genesis.Therefore,HE can be considered a result of a dysregulated gut-liverbrain axis function,where cognitive impairment can be reversed or prevented by the beneficial effects induced by“gut-centric”therapies,such as non-absorbable disaccharides,non-absorbable antibiotics,probiotics,prebiotics,and fecal microbiota transplantation.In this context dietary modifications,by modulating the intestinal milieu,can also provide significant benefit to cirrhotic patients with HE.This review will provide a comprehensive insight into the mechanisms responsible for gut-liver-brain axis dysregulation leading to HE in cirrhosis.Furthermore,it will explore the currently available therapies and the most promising future treatments for the management of patients with HE,with a special focus on the dietary approach. | Daniela Campion Ilaria Giovo Paola Ponzo Giorgio M Saracco Federico Balzola Carlo Alessandria | 2019 | World Journal of Hepatology2019，11，6： | 8 |
