Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease (NAFLD). The minimal pathologic criteria for NASH include hepatic steatosis, ballooning degeneration, and lobular inflammation. The resolution of NASH, which relies on the loss of ballooning degeneration, is subject to sampling and observer variability in pathologic interpretation. Ballooning is associated with advanced hepatic fibrosis in cross-sectional studies but is not a predictor of mortality in NAFLD. Fibrosis staging, while still subject to some sampling variability, has less observer variability and is a robust predictor of liver-related mortality in NAFLD...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease whose prevalence has been increasing constantly and linked to the global obesity epidemic. The NAFLD histologic spectrum ranges from simple steatosis to nonalcoholic steatohepatitis (NASH), which can progress to cirrhosis and hepatocellular carcinoma. Liver biopsy is the only reliable means to diagnose and stage NASH, but its invasive nature limits its use. Therefore, the prediction of hepatic injury by means of the development of new noninvasive tests represents a growing medical need...

Mouse models of obesity (ob/ob) and diabetes (db/db) in which the leptin (Lep) and Leptin receptor (Lepr) genes have been mutated, respectively, have contributed to a better understanding of human obesity and type 2 diabetes and to the prevention, diagnosis, and treatment of these metabolic diseases. In this study, we report the first CRISPR-Cas9-induced Lep and Lepr KO mouse models by co-microinjection of Cas9 mRNA and sgRNAs that specifically targeted Lep or Lepr in C57BL/6J embryos. Our newly established Lep and Lepr knockout (KO) mouse models showed phenotypic disorders nearly identical to those found in ob/ob and db/db mice, such as an increase in body weight, hyperglycemia, and hepatic steatosis...

BACKGROUND & AIMS: Gasdermin D (GSDMD)-executed programmed necrosis is involved in inflammation and controls interleukin (IL)-1β release. However, the role of GSDMD in non-alcoholic steatohepatitis (NASH) remains unclear. We investigated the role of GSDMD in the pathogenesis of steatohepatitis. METHODS: Human liver tissues from patients with non-alcoholic fatty liver disease (NAFLD) and control individuals were obtained to evaluate GSDMD expression. Gsdmd knockout (Gsdmd-/-) mice, obese db/db mice and their wild-type (WT) littermates were fed with methionine-choline deficient (MCD) or control diet to induce steatohepatitis...

Celiac disease (CD) has been associated with several genetic and immune disorders, but association between CD and hereditary fructose intolerance (HFI) is extremely rare. HFI is an autosomal recessive disease caused by catalytic deficiency of aldolase B (fructose-1,6-bisphosphate aldolase). We report the case of a 5-year-old boy suffering from CD, admitted with an initial diagnosis of Reye's-like syndrome. He presented with episodic unconsciousness, seizures, hypoglycemia, hepatomegaly and abnormal liver function...

Non-alcoholic fatty liver disease (NAFLD) is the most common form of liver disease and ranges from isolated steatosis to NASH. To determine whether circulating fatty acids could serve as diagnostic markers of NAFLD severity and whether specific fatty acids could contribute to the pathogenesis of NASH, we analyzed two independent NAFLD patient cohorts and used the methionine- and choline-deficient diet (MCD) NASH mouse model. We identified six fatty acids that could serve as non-invasive markers of NASH in patients with NAFLD...

Non-alcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease in the developed world (15% to 40% of the adult population). Introduction of lifestyle changes including dietary intervention and increased physical activity is most often the first-line treatment and is intended to support not only the treatment of liver disease, but also for diseases associated with obesity, insulin resistance, diabetes and dyslipidemia. In addition to well-known metformin, there are new classes of antidiabetic drugs, including GLP-1analog, SGLT-2 antagonist, pioglitazon...

NAFLD is a spectrum comprised of isolated steatosis, NASH, advanced fibrosis, and cirrhosis. The majority of NAFLD subjects do not have NASH and don't carry a significant risk for adverse outcomes (cirrhosis and mortality). Globally, the prevalence of NAFLD is approximately 25%. In Asia, a gradient of high prevalence rates to low rates are noted from urban to rural areas. Given the prevalence of NAFLD, the clinical and economic burden of NAFLD and NASH can be substantial. With increasing recognition as an important liver disease, the diagnosis of NASH still requires a liver biopsy which is suboptimal...

Metal phosphides, particularly zinc and aluminum phosphide, occasionally poison horses and other equids following their use as rodenticides and insecticides. Grain-based aluminum phosphide baits are used to control rodents such as prairie dogs. The clinical course in intoxicated horses is short (<24-48 h), and animals may be found dead. Hepatic lesions caused by phosphine poisoning are not well described. Laboratory confirmation depends on detecting phosphine gas in gastric contents. Eight horses and a mule were exposed to zinc phosphide used to control prairie dogs on a Wyoming ranch...

Non-alcoholic fatty liver disease (NAFLD) is a disease characterized by a steatosis of the liver that may progress to more serious pathological conditions including: nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. As the prevalence of NAFLD has increased worldwide in recent years, pathophysiology and risk factors associated with disease progression of NAFLD are at the focus of many studies. NAFLD is related to and shares common serum biomarkers with cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), obesity, and metabolic syndrome (MetS)...

MRI is now the reference method for detecting and quantifying hepatic and extrahepatic iron overload, regardless of its cause. The decrease of the hepatic signal is proportional to the amount of iron in the tissues. It is more pronounced with T2*-weighted gradient echo sequences. It increases proportionally with the strength of the magnetic field. Thus a 3-T MRI is be more sensitive and probably more accurate to detect a slight iron overload, as seen in dysmetabolic hepatosiderosis. Conversely, a 1.5-T MRI better estimates a high overload...

OBJECTIVE: To describe a case of cholesteryl ester storage disease (CESD) and discuss the importance of liver biopsy for diagnosis. CASE DESCRIPTION: A female patient, aged two years and ten months, presented with an increased abdominal volume following hepatomegaly for four months. Abdominal ultrasound demonstrated hepatomegaly and hepatic steatosis. Laboratory tests showed elevated liver serum enzymes and dyslipidemia. Liver biopsy was consistent with CESD. COMMENTS: Although measuring enzyme activity is the gold standard for CESD diagnosis, liver biopsy is very helpful when investigating suspected cases of CESD, particularly upon other differential diagnoses to be considered...
