Microbial function, especially related to bile acid metabolism, can modulate alcohol-associated injury even in the presence of cirrhosis and alcoholic hepatitis. Microbial culture studies detect only a small number of the species of intestinal bacteria.

Loomba R, Sanyal AJ. Specific alterations in the gut—liver—brain axis that are complicit in the interactions between the gut microbiota and alcohol addiction are also reviewed.

The bacteria obtain nutrients within the protected anoxic microenvironment of the human intestine. There are thus many concerns about the public health impact of childhood obesity and its clinical consequences [ 4 ]. Fecal microbiome and volatile organic compound metabolome in obese humans with nonalcoholic fatty liver disease.

Obesity, fatty liver disease and intestinal microbiota

It is therefore not surprising that recent literature emphasizes a potential role for gut dysbiosis in the pathophysiology of NAFLD. It encompasses a disease spectrum ranging from simple steatosis to nonalcoholic steatohepatitis NASHwhich is histologically characterized by hepatocyte injury, inflammation and variable degrees of fibrosis.

Bosscher D, Breynaert A, Pieters L, Hermans N Food-based strategies to modulate the composition of the intestinal microbiota and their associated health effects.

Microbiota, Obesity and NAFLD

Recent evidence has introduced gut microbiota as a new crucial player in this complex story. Clin Liver Dis 18 1: Metagenomic analysis and 16S ribosomal RNA gene sequencing, which is specific for prokaryotic ribosomes, have shown that Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria are the predominant bacterial phyla among the intestinal bacteria in adults [ 1718 ].

J Appl Toxicol 34 6: These findings demonstrate that host genetic background, diet, and the gut microbiota interact to influence NAFLD pathogenesis in humans, as is now known to occur in rodent models.

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

PubMed Google Scholar Sookoian S, Pirola CJ. Sequencing gut microbiota before the diet identified two classes of bacteria that predicted choline-deficiency-induced fatty liver: Branched-chain fatty acids, which can be de novo synthetized by several gut bacterial species, have been associated with insulin resistance and metabolic disease development [ 14 ].

HFD-related increases in liver fibrosis were associated with gut dysbiosis, especially an increase in Proteobacteria. Other potential mechanisms are emerging rapidly.

Alcohol, liver disease and the gut microbiota

Overall, the known contributing factors are limited in their ability to explain the rising prevalence of obesity [ 7 ]. CMAJ Open 3 3: J Lipid Res 48 9: Distinctly altered gut microbiota in the progression of liver disease. Allard states that there is no conflict of interest. S CrossRef Google Scholar The severity of nonalcoholic fatty liver disease is associated with gut dysbiosis and shift in the metabolic function of the gut microbiota.

Several genes contribute to weight gain by controlling feeding behavior, energy expenditure and metabolism, but can only partially account for the development of obesity.Changes in gut microbiota due to supplemented fatty acids in diet-induced obese mice - Volume Issue 4 - Jorge R.
