A Structured Literature Review of the Epidemiology and Disease Burden of Non-Alcoholic Steatohepatitis (NASH)

ConclusionThis first broad-ranging examination of NASH literature revealed a paucity of evidence, with poor-quality, small studies found. The overwhelming impact of NASH and its patient and healthcare burden is evident. Further evidence is needed to improve our understanding of NASH, especially as fibrosis stages advance.FundingGilead Science Inc.

This is so far the first meta ‐analysis about TM6SF2 polymorphisms and chronic liver disease. Our pooled analyses suggested that rs58542926 polymorphism was significantly associated with chronic liver disease in both Asians and Caucasians. Future investigations are warranted to explore potential roles of other TM6SF2 polymorph isms in the development of chronic liver disease. AbstractBackgroundSome genetic association studies tried to investigate potential associations of transmembrane 6 superfamily member 2 (TM6SF2) polymorphisms with chronic liver disease. However, the results of these studies were not consistent. Thus...

The recent epidemic in chronic liver disease is related to the burden of Non-Alcoholic Fatty Liver Disease (NAFLD), paralleling the worldwide increase of obesity. [1] NAFLD is a complex condition related to metabolic derangements in insulin resistance (IR), but in a subset of patients the liver becomes the target of multiple hits leading to Non-Alcoholic SteatoHepatitis (NASH), the histological phenotype that may progressively develop liver fibrosis, cirrhosis and possibly hepatocellular carcinoma.

[Microbiome &NASH - partners in crime driving progression of fatty liver disease]. Z Gastroenterol. 2019 Jul;57(7):871-882 Authors: Wree A, Geisler LJ, Tacke F Abstract Along with the increasing prevalence of obesity, metabolic syndrome and type 2 diabetes, non-alcoholic fatty liver disease (NAFLD) is rapidly increasing and poses a major challenge for gastroenterologists. Many studies have demonstrated that the microbiome is closely associated with the progression of nutrition-related diseases, especially of fatty liver disease. Changes in the quantity and quality of the intestinal flora, commonly...

Abstract Non-alcoholic fatty liver disease (NAFLD) is histologically classified as either non-alcoholic fatty liver or non-alcoholic steatohepatitis (NASH). NASH is the progressive subtype of NAFLD. Individuals with NASH are at significant risk of developing hepatic fibrosis, cirrhosis, hepatocellular carcinoma, and liver-related and all-cause mortality. NAFLD is closely associated with obesity, type 2 diabetes mellitus (T2DM), metabolic syndrome, and cardiovascular events. Its prevalence is estimated to be above 30% in Turkey; and recent studies confirm this estimate. According to these studies, the prevalence of...

Abstract Nonalcoholic fatty liver disease (NAFLD) is a heterogeneous and complex disease that is imprecisely diagnosed by liver biopsy. NAFLD covers a spectrum that ranges from simple steatosis, nonalcoholic steatohepatitis (NASH) with varying degrees of fibrosis, to cirrhosis, which is a major risk factor for hepatocellular carcinoma. Lifestyle and eating habit changes during the last century have made NAFLD the most common liver disease linked to obesity, type 2 diabetes mellitus and dyslipidemia, with a global prevalence of 25%. NAFLD arises when the uptake of fatty acids (FA) and triglycerides (TG) from circul...

This study aims to determine the effect of type 2 diabetes mellitus and insulin therapy on non-alcoholic fatty liver disease in the patients with morbid obesity. MATERIAL AND METHODS: Clinical, anthropometric and laboratory data were analyzed together with intraoperative liver biopsies from morbidly obese patients undergoing bariatric surgery. RESULTS: 219 patients with morbid obesity were evaluated. Systemic arterial hypertension (55.9% vs. 33.8%, p = 0.004) and dyslipidemia (67.1% vs. 39.0%, p

Liver disease constitutes the third most common cause of premature death in the UK, and its prevalence is substantially higher compared to other countries in Western Europe.[1 –3] Excess liver iron is associated with increased severity and progression of liver diseases including cirrhosis and hepatocellular carcinoma in individuals with non-alcoholic fatty liver disease (NAFLD), [4–6] and is the direct cause of liver disease in those with hereditary haemochromatosis a nd thalassaemia.[7,8] Observational associations have been described between excess liver iron content and several metabolic diseases such as hig...

In conclusion; our results ring a bell inviting the development of a roadmap for liver research in Egypt targeting to put future policies to cover areas of weakness in liver research with an ultimate goal of tackling liver disease and its overwhelming socioeconomic burden in our developing country.

Authors: Iida A, Kuranuki S, Yamamoto R, Uchida M, Ohta M, Ichimura M, Tsuneyama K, Masaki T, Seike M, Nakamura T Abstract The changes in free amino acid (AA) levels in blood during the progression from non-alcoholic steatohepatitis (NASH) to hepatocellular carcinoma (HCC) are unclear. We investigated serum AA levels, along with biochemical and histological events, in a mouse model of NASH. We induced NASH in male C57BL/6J mice with a streptozotocin injection and high-fat diet after 4 weeks of age (STAM group). We chronologically (6, 8, 10, 12, and 16 weeks, n=4-12 mice/group) evaluated the progression from steatoh...

Abstract Non-alcoholic fatty liver disease (NAFLD) represents the most common form of chronic liver disease worldwide (about 25% of the general population); and 3-5% of patients develop non-alcoholic steatohepatitis (NASH), characterized by hepatocytes damage, inflammation and/or fibrosis, which can progress to cirrhosis and/or develop hepatocellular carcinoma (HCC). The pathogenesis of NAFLD, particularly the mechanisms whereby a minority of patients develop a more severe phenotype is still incompletely understood. In this review we examine the available literature on initial mechanisms of hepatocellular damage a...
