1Evaluation of gut dysbiosis using serum and fecal bile acid profiles显示文摘Dysbiosis in the intestinal microflora can affect the gut production of microbial metabolites,and toxic substances can disrupt the barrier function of the intestinal wall,leading to the development of various diseases.Decreased levels of Clostridium subcluster XIVa(XIVa)are associated with the intestinal dysbiosis found in inflammatory bowel disease(IBD)and Clostridium difficile infection(CDI).Since XIVa is a bacterial group responsible for the conversion of primary bile acids(BAs)to secondary BAs,the proportion of intestinal XIVa can be predicted by determining the ratio of deoxycholic acid(DCA)/[DCA+cholic acid(CA)]in feces orserum.For example,serum DCA/(DCA+CA)was significantly lower in IBD patients than in healthy controls,even in the remission period.These results suggest that a low proportion of intestinal XIVa in IBD patients might be a precondition for IBD onset but not a consequence of intestinal inflammation.Another report showed that a reduced serum DCA/(DCA+CA)ratio could predict susceptibility to CDI.Thus,the BA profile,particularly the ratio of secondary to primary BAs,can serve as a surrogate marker of the intestinal dysbiosis caused by decreased XIVa.Tadakuni Monma Junichi Iwamoto Hajime Ueda Makoto Tamamushi Fumio Kakizaki Naoki Konishi Shoichiro Yara Teruo Miyazaki Takeshi Hirayama Tadashi Ikegami Akira Honda 2022World Journal of Clinical Cases2022,10,34:0
