Intestinal ecosystem contains trillions of microorganisms including bacteria, Archaea, yeasts and viruses.

Microbiota, Obesity and NAFLD

The intestinal microbiome can increase the efflux of free fatty acids to the liver by influencing intestinal expression of the lipoprotein lipase inhibitor Fiaf fasting-induced adipose factor, also known as angiopoietin-like protein-4 [ 910 ].

Obesity develops primarily because energy intake exceeds energy expenditure, and many environmental and host factors interact in complex ways to contribute to its development [ 7 ].

Gut Microbiota and Clinical Disease: Obesity and Nonalcoholic Fatty Liver Disease

Sci Trans Med 5 The fetal intestine is sterile. Gut Microbiota—Environment Interactions There are thousands of bacterial species in the gut, and they all display an incredibly wide range of metabolic functions. Changes prompted by spesific intestinal microbiota are characterized not only by a general obesogenic and dysmetabolic framework but also by a specific de novo hepatic lipogenesis[ 10 ].

In patients who have substantial liver fibrosis, gut microbial changes occur in parallel to liver injury, with an increase in endotoxin-producing and a reduction in autochthonous bacterial taxa, which continue through active drinking in cirrhosis until alcoholic hepatitis.

Epidemiologic studies indicate that NAFLD is now the most common cause of liver disease in many countries, including the United States [ 5 ]. Genes Nutr 6 3: The bacteria obtain nutrients within the protected anoxic microenvironment of the human intestine.

Microbiota Abstract Alcoholic liver disease, which ranges from mild disease to alcoholic hepatitis and cirrhosis, is a leading cause of morbidity and mortality worldwide.

Toll-like receptor-4 signaling and Kupffer cells play pivotal roles in the pathogenesis of non-alcoholic steatohepatitis.

Interestingly, Escherichia are known alcohol-producing bacteria, and serum alcohol concentration was significantly higher in NASH patients compared to obese or control groups.

Gpr41 is a receptor for the binding of short chain fatty acids produced by fermentation of polysaccharides by gut microbes. The role of intestinal bacteria in the development of dietary cirrhosis in rats.

Obesity, fatty liver disease and intestinal microbiota

NAFLD encompasses a spectrum of hepatic pathology i. Strategies that address both alcohol cessation and microbiota alteration are needed for meaningful improvement in the natural history of this multifaceted disorder. Liver Int. Functional microbial changes, in particular, hepatic bile acid production and bacterial biotransformation, are altered in parallel with the disease stages and differ between actively drinking patients with cirrhosis and those with alcoholic hepatitis.

Gastroenterology 6: They hypothesized that the activated TLR4 provoked gastrointestinal inflammation that was associated with the appearance of hyperphagia and an obese phenotype. Obesity can cause hyperlipidemia, cardiovascular diseases, metabolic syndrome and non-alcoholic fatty liver disease NAFLD.

Bile acids are ligands for the farnesoid X receptor FXR and the G-protein-coupled receptor TGR5, both having been implicated in metabolic syndrome pathobiology [ 2223 ]. · This Review focuses on clinical studies involving the gut microbiota in patients with alcoholic liver disease across the spectrum from alcoholic fatty liver to cirrhosis and alcoholic hepatitis Cited by: 1.

Alcohol, liver disease and the gut microbiota

Abstract. Despite evidence that the intestinal microbiota (IM) is involved in the pathogenesis of obesity, the IM composition of patients with nonalcoholic fatty liver disease (NAFLD) has not.
