Altered Fecal Microbiota Correlates with Liver Biochemistry in Nonobese Patients with Non-alcoholic Fatty Liver Disease
Increasing evidence suggests a role of intestinal dysbiosis in obesity and non-alcoholic fatty liver disease ( NAFLD ) . But it remains unknown in nonobese NAFLD . This prospect i ve , cross-sectional study sought to characterize differences in fecal microbiota between nonobese adult individuals with and without NAFLD and their potential association with metabolic markers of disease progression . A total of 126 nonobese subjects were enrolled : 43 NAFLD and 83 healthy controls ( HC ) . The microbial community was profiled by denaturing gradient gel electrophoresis and examined by 454 pyrosequencing of the 16S ribosomal RNA V3 region . Lower diversity and a phylum-level change in the fecal microbiome were found in NAFLD . Compared with HC , patients had 20 % more phylum Bacteroidetes ( p = 0.005 ) and 24 % less Firmicutes ( p = 0.002 ) . Within Firmicutes , four families and their 8 genera , which were short-chain fatty acids-producing and 7α-dehydroxylating bacteria , were significantly decreased . Moreover , Gram-negative ( G− ) bacteria were prevalent in NAFLD ( p = 0.008 ) . Furthermore , a significant correlation with metabolic markers was revealed for disturbed microbiota in NAFLD . This novel study indicated that intestinal dysbiosis was associated with nonobese NAFLD and might increase the risk of NAFLD progression
