Nonalcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD) are some of the most common liver diseases worldwide. The human gut microbiome is dynamic and shifts in bacterial composition have been implicated in many diseases. Studies have shown that there is a shift in bacterial overgrowth favoring pro-inflammatory mediators in patients with advanced disease progression such as cirrhosis. Further investigation demonstrated that the transplantation of gut microbiota from advanced liver disease patients can reproduce severe liver inflammation and injury in mice. Various techniques in manipulating the gut microbiota have been attempted including fecal transplantation and probiotics. This review focuses on the changes in the gut microbiota as well as emerging lines of microbiome work with respect to NAFLD and ALD.
非酒精性脂肪性肝病(NAFLD)和酒精性肝病(ALD)是全球最常见的一些肝脏疾病。人类肠道微生物群是动态的,细菌组成的变化与许多疾病有关。研究表明,在诸如肝硬化等疾病进展晚期的患者中,细菌过度生长出现了有利于促炎介质的转变。进一步的研究表明,将晚期肝病患者的肠道微生物群移植到小鼠体内可导致严重的肝脏炎症和损伤。人们尝试了各种操纵肠道微生物群的技术,包括粪便移植和益生菌。本综述重点关注肠道微生物群的变化以及在NAFLD和ALD方面微生物组研究的新进展。
