Gut microbiota and non-alcoholic fatty liver disease.

The gastrointestinal tract of the adult human represents the habitat of the ecological community of commensal, symbiotic and pathogenic microorganisms, defined as the gut microbiota, which has more than 100 trillion microorganisms representing one of the most complex ecosystems. Colonization of the gastrointestinal tract by microorganisms begins at the time of birth. Contrary to what was previously hypothesized, a large number of fundamental functions for the host are attributed to the gut microbiota to date. Therefore, the gut microbiota does not represent a passive set of microbes hosted inside the human organism but plays a crucial role in the balance of the organism itself. An alteration of the microbiota is a phenomenon known as dysbiosis. The latter can be implicated in the development of complex liver diseases like non-alcoholic fatty liver disease. The aim of this review was to describe the most interesting data linking the development of non-alcoholic fatty liver disease with the gut microbiota and, therefore, to underline the importance of the microbiota itself, as a potential therapeutic target in the treatment of non-alcoholic fatty liver disease.

Gut microbiota in inflammatory bowel disease: a target for therapy not to be missed.

In the last years, the gut microbiota achieved great importance, since several studies demonstrated its correlation with the immune system and with the maintenance of intestinal homeostasis, as well as with the regulation of the integrity of the epithelium and the intestinal motility. An imbalance in microbial species promotes a dysbiosis, which has been associated with chronic diseases such as metabolic syndrome, inflammatory diseases, and some behavior disorders. The association with gut microbiota and dysbiosis has been demonstrated mostly in inflammatory bowel disease (IBD). Several studies investigated the application of antibiotics, prebiotics, probiotics, and fecal microbiota transplantation in the treatment strategies for IBD. In this review, we discuss the recent findings on the potential role of the gut microbiota manipulation, with particular attention to bacterial microbiota, which could be implicated for a successful IBD therapeutic approach.

Effectiveness and Safety of Golimumab in Treating Outpatient Ulcerative Colitis: A Real-Life Prospective, Multicentre, Observational Study in Primary Inflammatory Bowel Diseases Centers.

BACKGROUND AND AIMS: Golimumab (GOL) has been recently approved in Italy for the treatment of ulcerative colitis (UC) unresponsive to standard treatments. Our aims were to assess the real-life efficacy and safety of GOL in managing UC outpatients in Italian primary Inflammatory Bowel Diseases (IBD) centres. METHODS: Consecutive UC outpatients with at least 3-months follow-up were enrolled. Primary end-point was the induction and maintenance of remission in UC, defined as Mayo score
