Mechanisms of Fibrosis Development in NASH

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent liver disease world-wide, affecting 20-25% of the adult population. In 25% of patients, NAFLD progresses to non-alcoholic steatohepatitis (NASH), which increases the risk for the development of cirrhosis, liver failure and hepatocellular carcinoma. In patients with NASH, liver fibrosis is the main determinant of mortality. Here, we review how interactions between different liver cells culminate in fibrosis development in NASH, focusing on triggers and consequences of hepatocyte-macrophage-hepatic stellate cell (HSC) crosstalk.

Abstract Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease affecting approximately 25% of the global population. There is a collinearity between the severity of NAFLD and the components of the metabolic syndrome. NAFLD is also independently associated with cardiovascular disease and type 2 diabetes mellitus (T2DM). The progressive potential of non-alcoholic fatty liver disease (NAFLD) is today indisputable, and the histological spectrum of NAFLD ranges from isolated steatosis to non-alcoholic steatohepatitis (NASH), with risk of developing fibrosis and subsequent cirrhosis...

AbstractThe growing burden of non-alcoholic fatty liver disease (NAFLD) parallels the increasing prevalence of obesity in Asia. The overall prevalence of NAFLD in Asia is now estimated to be 29.6% and may have surpassed that in Western populations. NAFLD increases with increasing age and is closely associated with metabolic syndrome. Ethnic differences exist in the prevalence of NAFLD, but the underlying factors are unclear. There were initial concerns about lean NAFLD being associated with more severe liver disease and increased mortality, but subsequent studies suggested otherwise. Only some NAFLD patients progress to de...

Basel, 4 March 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Device Designation to the Elecsys ® GALAD score.* This algorithmic score combines gender and age with the biomarker results of the Elecsys AFP, AFP-L3 and PIVKA-II and is intended to aid diagnosis of early stage hepatocellular carcinoma (HCC). Dr. Amit Singal, Medical Director of the Liver Tumor Program   and Clinical Chief of Pathology at UT Southwestern Medical Center in Dallas, USA, stated, " HCC is the fourth leading cause of cancer-related death worldwide, wit...

Abstract Nonalcoholic fatty liver disease (NAFLD) is rapidly becoming the most common cause of chronic liver disease worldwide. This is primarily driven by the global epidemic of obesity and diabetes as well as the ageing of the general population. Most of the data regarding the epidemiology of NAFLD is published from the studies originating in the U.S. The overall prevalence of NAFLD in the United States is estimated to be 24%. In the U.S., Hispanic Americans have a higher prevalence of NAFLD, whereas African Americans have lower prevalence of NAFLD. The exact contributions of genetic and environmental factors on...

Non-alcoholic fatty liver disease (NAFLD) is a multifactorial disorder of hepatic lipid metabolism that leads to steatosis, and can progress to cirrhosis and hepatocellular carcinoma, usually in conjunction with over-nutrition and the metabolic syndrome.1 A central molecular driver of progression is lipotoxicity, a process involving multiple lipid species and pathways that result in hepatocyte damage, liver inflammation and fibrogenesis.2

ConclusionA substantial further reduction in cases of HCC requires a wider application of universal HBV vaccination and effective treatment of HBV- and HCV-related chronic hepatitis and cirrhosis, more effective campaigns to favor correct dietary habits and reduce alcohol consumption and the intensification of studies on HCC pathogenesis for future optimized prevention strategies.

Nonalcoholic fatty liver disease (NAFLD) is an increasingly recognized public health problem, affecting up to a quarter of the world's adult population. The burden of NAFLD is influenced by the epidemics of obesity and type 2 diabetes mellitus (T2DM) and the prevalence of these conditions is not expected to decrease in the forthcoming decades. Consequently, the burden of NAFLD-related liver complications (non-alcoholic steatohepatitis [NASH], cirrhosis and hepatocellular carcinoma) and the need for life-saving liver transplantation are also expected to increase further in the near future.

Nonalcoholic fatty liver disease (NAFLD) is a leading etiology for chronic liver disease with immense public health impact, affecting over 25% of the U.S. and global population, of whom up to one in four may have non-alcoholic steatohepatitis (NASH). NASH is associated with significant morbidity and mortality due to complications of liver cirrhosis, hepatic decompensation, and hepatocellular carcinoma (HCC). Recent data confirm that HCC represents the 5th most common cancer and 2nd leading cause of cancer-related death worldwide, and NAFLD has been identified as a rapidly emerging risk factor for this malignancy.

Abstract Metabolic disorders are increasingly leading to non-alcoholic fatty liver disease, subsequent steatohepatitis, cirrhosis and hepatocellular carcinoma. Fibroblast growth factors and their receptors play an important role in maintaining metabolic homeostasis also in the liver and disorders in signaling have been identified to contribute to those pathophysiologic conditions leading to hepatic lipid accumulation and chronic inflammation. While specific and well tolerated inhibitors of fibroblast growth factor receptor activity are currently developed for (non-liver) cancer therapy, treatment of non-alcoholic ...

Abstract Alcoholic and non-alcoholic fatty liver diseases have become a serious concern whole over the world. Both these liver diseases have an identical pathology, starting from simple steatosis to cirrhosis and ultimately to hepatocellular carcinoma. Treatment options for alcoholic liver disease (ALD) are still same as it was 50 years ago which includes corticosteroids, pentoxifylline, antioxidants, nutritional support and abstinence; and for non-alcoholic fatty liver disease (NAFLD) weight loss, insulin sensitizers, lipid lowering agents and anti-oxidants are the only treatment options. Despite of broad researc...
