Fecal deoxycholic acid associates with diet, intestinal microbes and total bilirubin in primary sclerosing cholangitis

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease with a strong association with inflammatory bowel disease and variable disease progression. We aimed to gain insights into the role of fecal bile acids (BA) on disease progression by determining the relationships between fecal BA, diet, and gut microbes, with markers of disease progression, BA synthesis, and farnesoid X receptor (FXR) activity.
