Helicobacter pylori(H.pylori)infection is widely prevalent worldwide.H.pylori infection has been reported to be a risk factor for the development of insulin resistance,nonalco-holic fatty liver disease(NAFLD),nonalcoholic steatohepatitis(NASH),liver fibrosis,and cirrhosis.Because treatment for NAFLD,other than weight loss is limited,the treatment for H.pylori infection is well established.It is important to determine whether screening and treatment for H.pylori infection should be considered in patients with no gastrointestinal symptoms.The aim of this mini-review is to evaluate the association be-tween H.pylori infection and NAFLD including epidemiology,pathogenesis,and the evidence for H.pylori infection as a modifiable risk factor for preventing or treating NAFLD. 展开更多

Nonalcoholic steatohepatitis(NASH)has emerged as the leading cause of chronic liver disease worldwide and is rapidly increasing in prevalence due to the obesity epidemic.There are currently no Food and Drug Administration(FDA)approved drugs to treat NASH,and therefore a critical need exists for novel therapies that can halt or reverse the progression to hepatic fibrosis,cirrhosis,and hepatocellular carcinoma.Clinical trials to date using single drugs to treat NASH have shown disappointing efficacy.Combination therapies to attack different targets underlying disease pathogenesis of NASH are being explored as a strategy currently.Novel RNA therapies are also being developed to target previously“undruggable”targets and are close to the maturity necessary to be viable therapeutic approaches for the treatment of NASH and fibrosis.Identifying circulating biomarkers of fibrosis could serve as a valuable,non-invasive diagnostic tool to guide clinical practice.Despite progress in translational and clinical research,one of the major reasons for the absence of effective therapeutics is our incomplete understanding of the pathophysiology that underlies the progression from steatosis to NASH and its most deadly consequence-fibrosis.Multi-omics platforms will help to drive effective precision medicine development in NASH and hepatology. 展开更多

非酒精性脂肪性肝炎(Nonalcoholic steatohepatitis,NASH)是由肥胖、Ⅱ型糖尿病、高脂血症、快速减肥、长期全肠道外营养(TPN)、空-回肠旁路手术及药物等多种危险因素引起的一种较新的临床病理综合征。NASH发病机制非常复杂,许多前期研... 非酒精性脂肪性肝炎(Nonalcoholic steatohepatitis,NASH)是由肥胖、Ⅱ型糖尿病、高脂血症、快速减肥、长期全肠道外营养(TPN)、空-回肠旁路手术及药物等多种危险因素引起的一种较新的临床病理综合征。NASH发病机制非常复杂,许多前期研究虽然获得了初步资料,但对NASH的发病机制还没有十分明确。目前认为,FFA蓄积、氧化应激、胰岛耐受、P450(CYP2E1或CYP4A)、瘦素、Kupffer细胞及细胞因子等在NASH的发病中起重要作用。 展开更多
