Development of Alcohol-Associated Hepatitis Is Associated With Specific Changes in Gut-Modified Bile Acids.

ABSTRACT: The perturbations in bile acids (BAs) in alcohol-associated hepatitis (AH) and its relationship to disease severity is not well defined. The aims of this study were to define (1) the effects of heavy alcohol consumption on BAs and related microbiome, (2) the additional changes with AH, and (3) the relationship of these changes to disease severity. In this multicenter study, plasma and fecal BAs and related microbiome were interrogated in healthy individuals, heavy drinking controls (HDCs) without overt liver disease, and AH. Compared to healthy controls, HDCs had increased glycine-conjugated 7α and 27α primary BAs and increased secondary BA glycocholenic sulfate (multiple-comparison adjusted P < 0.05 for all). Plasma-conjugated cholic and chenodeoxycholic acid increased in AH along with th
