Moderate alcohol consumption in patients with nonalcoholic fatty liver disease (NAFLD) is common, yet the effects on cardiovascular and liver health are unclear. Moderate alcohol use is associated with improved insulin sensitivity and decreased cardiovascular mortality in the general population but whether similar benefits are seen in persons with NAFLD is largely unstudied. There is significant overlap in the pathogenesis of alcoholic liver disease (ALD) and NAFLD although studies of ALD have focused on pathologic alcohol intake and few mechanistic studies of moderate alcohol use in NAFLD exist...

Nonalcoholic fatty liver disease (NAFLD) has been found to be highly prevalent in psoriatic patients. Adult onset psoriasis could be divided into either early or late onset psoriasis. The associations between NAFLD and related metabolic comorbidities and age at onset of psoriasis have not yet been investigated. Our study was to evaluate the associations between prevalence of NAFLD and related metabolic conditions and early, late, and childhood onset psoriasis. A cross-sectional observational study was conducted on patients with moderate to severe plaque psoriasis...

BACKGROUND/OBJECTIVES: Helicobacter pylori (H. pylori) is the most common chronic bacterial infection. Patients with H. pylori infection may be at an increased risk of nonalcoholic fatty liver disease (NAFLD) because of chronic inflammation and insulin resistance. Several epidemiologic studies attempting to determine this risk have yielded inconsistent results. This meta-analysis was conducted with the aims to summarize all available evidence and estimate the risk of NAFLD in patients with H...

BACKGROUND & AIMS: N-linked glycosylation of proteins is critical for proper protein folding and trafficking to the plasma membrane. Drug transporters are one class of proteins that have reduced function when glycosylation is impaired. N-linked glycosylation of plasma proteins has also been investigated as a biomarker for several liver diseases, including non-alcoholic fatty liver disease (NAFLD). The purpose of this study was to assess the transcriptomic expression of genes involved in protein processing and glycosylation, and to determine the glycosylation status of key drug transporters during human NAFLD progression...

REVIEW
Alejandro Gugliucci
Fructose is associated with the biochemical alterations that promote the development of metabolic syndrome (MetS), nonalcoholic fatty liver disease, and type 2 diabetes. Its consumption has increased in parallel with MetS. It is metabolized by the liver, where it stimulates de novo lipogenesis. The triglycerides synthesized lead to hepatic insulin resistance and dyslipidemia. Fructose-derived advanced glycation end products (AGEs) may be involved via the Maillard reaction. Fructose has not been a main focus of glycation research because of the difficulty in measuring its adducts, and, more importantly, because although it is 10 times more reactive than glucose, its plasma concentration is only 1% of that of glucose...

Hepatic steatosis is caused by metabolic imbalances that could be explained in part by an increase in de novo lipogenesis that results from increased sterol element binding protein 1 (SREBP-1) activity. The nuclear receptor liver receptor homolog 1 (LRH-1) is an important regulator of intermediary metabolism in the liver, but its role in regulating lipogenesis is not well understood. Here, we have assessed the contribution of LRH-1 SUMOylation to the development of nonalcoholic fatty liver disease (NAFLD). Mice expressing a SUMOylation-defective mutant of LRH-1 (LRH-1 K289R mice) developed NAFLD and early signs of nonalcoholic steatohepatitis (NASH) when challenged with a lipogenic, high-fat, high-sucrose diet...

Superparamagnetic iron oxide nanoparticles (SPIONs) have recently been used as an effective magnetic resonance imaging (MRI) contrast agent for the noninvasive diagnosis of chronic liver diseases including nonalcohol fatty liver diseases, nonalcohol steatohepatitis, and cirrhosis as well as liver tumors. However, the potential risk of the iron overload by SPIONs has been highly underestimated in chronic liver diseases. While most of SPIONs have been shown safe in the healthy group, significant toxicity potential by the iron overload has been revealed through immunotoxicity, lipid peroxidation, and fatty acid and cholesterol metabolism in cirrhosis as a high risk factor...

Chronic diseases that affect the gastrointestinal tract also tend to affect nutrition. The incidence of chronic liver disease is increasing. As the prevalence of obesity rises, so do the incidences of nonalcoholic fatty liver disease and nonalcoholic steatohepatitis. Patients with chronic liver disease usually have some degree of malnutrition. In the absence of encephalopathy, patients with chronic liver disease should consume more protein than that in the average diet. There is some controversy about whether diet plays a role in the development of inflammatory bowel disease...

Type 2 diabetes (T2DM) and nonalcoholic fatty liver disease (NAFLD) are highly prevalent in the community, and share common pathogenic mechanisms. There is also evidence that T2DM may be favored by hepatic fat accumulation; in turn the presence of T2DM is a risk factor for liver disease progression. The treatment of T2DM has considerably changed in the past few years; new drug classes, promoting glucose-lowering through mechanisms different from classical insulin-sensitizing or insulin-secreting action, have been added to continuing lifestyle intervention...

Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome. Studies have demonstrated that anthocyanin-rich foods may improve hyperlipidemia and ameliorate hepatic steatosis. Here, effects of Aronia melanocarpa (AM), known to be rich of anthocyanins, on hepatic lipid metabolism and adipogenic genes were determined. AM was treated to C57BL/6N mice fed with high fat diet (HFD) or to FL83B cells treated with free fatty acid (FFA). Changes in levels of lipids, enzymes and hormones were observed, and expressions of adipogenic genes involved in hepatic lipid metabolism were detected by PCR, Western blotting and luciferase assay...

Colorectal neoplasm is considered to have a strong association with nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS), respectively. The relationship among NAFLD, MetS, and colorectal neoplasm was assessed in 1793 participants. Participants were divided into 4 groups based on the status of NAFLD and MetS. Relative excess risks of interaction (RERI), attributable proportion (AP), and synergy index (SI) were applied to evaluate the additive interaction. NAFLD and MetS were significantly correlated with colorectal neoplasm and colorectal cancer (CRC), respectively...

BACKGROUND: Prevalent worldwide obesity is associated with increased incidence of nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome. The identification of noninvasive biomarkers for NAFLD is of recent interest. Because primary de novo lipogenesis occurs in chicken liver as in human liver, adult chickens with age-associated steatosis resembling human NAFLD is an appealing animal model. OBJECTIVE: The objective of this study was to screen potential biomarkers in the chicken model for NAFLD by transcriptomic and proteomic analysis...

NACHT-LRR-PYD-containing proteins 3 (NLRP3) inflammasome regulates the maturation and secretion of proinflammatory cytokines including interleukin-1β and interleukin-18, as well as immune and inflammatory response, through the activation of cysteine aspartate specific protease-1. Inflammatory response caused by the activation of NLRP3 inflammasome may participate in the development and progression of nonalcoholic fatty liver disease (NAFLD). Therefore, exploration of the role of NLRP3 inflammasome in NAFLD is important for the understanding of the pathogenesis of NAFLD and discovery of new therapeutic targets...

: Free cholesterol (FC) accumulation in the liver is an important pathogenic mechanism of nonalcoholic steatohepatitis (NASH). Plasmalogens, key structural components of the cell membrane, act as endogenous antioxidants and are primarily synthesized in the liver. However, the role of hepatic plasmalogens in metabolic liver disease is unclear. In this study, we found that hepatic levels of docosahexaenoic acid (DHA)-containing plasmalogens, expression of glyceronephosphate O-acyltransferase (Gnpat, the rate-limiting enzyme in plasmalogen biosynthesis), and expression of Pparα were lower in mice with NASH caused by accumulation of free cholesterol (FC) in the liver...

BACKGROUND & AIMS: No treatment for nonalcoholic fatty liver disease (NAFLD) has been approved by regulatory agencies. We performed a randomized controlled trial to determine whether 52 weeks of cysteamine bitartrate delayed release (CBDR) reduces the severity of liver disease in children with NAFLD. METHODS: We performed a double-masked trial of 169 children with NAFLD Activity Scores ≥ 4 at 10 centers. From June 2012 to January 2014, the patients were randomly assigned to receive CBDR or placebo twice daily (300 mg for ≤65 kg, 375 mg for >65-80 kg, 450 mg for >80 kg) for 52 weeks...

The microbiota control regional immunity using mechanisms such as inducing IL-17A-producing γδ T (γδT-17) cells in various tissues. However, little is known regarding hepatic γδT cells that are constantly stimulated by gut commensal microbes. Here we show hepatic γδT cells are liver-resident cells and predominant producers of IL-17A. The microbiota sustain hepatic γδT-17 cell homeostasis, including activation, survival and proliferation. The global commensal quantity affects the number of liver-resident γδT-17 cells; indeed, E...

Childhood obesity has emerged as an important public health problem in the United States and other countries in the world. Currently 1 in 3 children in the United States is afflicted with overweight or obesity. The increasing prevalence of childhood obesity is associated with emergence of comorbidities previously considered to be "adult" diseases including type 2 diabetes mellitus, hypertension, nonalcoholic fatty liver disease, obstructive sleep apnea, and dyslipidemia. The most common cause of obesity in children is a positive energy balance due to caloric intake in excess of caloric expenditure combined with a genetic predisposition for weight gain...
