Microbiome & NASH - partners in crime driving progression of fatty liver disease.

[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 referred to as dysbiosis, result in altered food metabolism, increased permeability of the intestinal barrier ("leaky gut") and consecutive inflammatory processes in the liver. This favors both the progression of obesity and metabolic disorders as well as NAFLD towards non-alcoholic steatohepatitis (NASH), hepatic fibrosis, cirrhosis and hepatocellular carcinoma (HCC). Important molecular mechanisms include microbial metabolites, microbial and endogenous signaling substances (so-called PAMPs/DAMPs) as well as bile acids. Essential cellular mechanisms include immune cells in the gut and liver, especially macrophages and Kupffer cells, as well as intestinal epithelial cells and hepatocytes as central regulators of metabolism. In this review article, we briefly summarize the relevant species of the human microbiome, describe the microbial analytics, ...

Diabetic foot ulcer (DFU) is a major health problem and remains a major cause of amputation across the world. Critical assessment of the relationship between peripheral artery disease, revascularization, and healing of DFU was performed. A new therapy has been claimed to prevent major amputations in advanced DFU. The intralesional injection of recombinant human epidermal growth factor (EGF) should often lead to satisfactory outcomes. The purpose of our study was to demonstrate the advantage of the combination of revascularization and EGF local infiltration in accelerating healing of DFU.

CONCLUSIONS: These data provide health care providers with predicted ranges of liver enzymes in patients with hepatocellular or cholestatic liver disease and may thereby help to identify patients with concurrent forms of liver disease. PMID: 31628070 [PubMed - as supplied by publisher]
