Abstract

BACKGROUND: Alcohol-associated liver disease (ALD) is an important cause of morbidity and mortality worldwide. The intestinal microbiota is involved in the development and progression of ALD; however, little is known about commensal fungi therein.

METHODS: We studied the dynamic changes of the intestinal fungal microbiome, or mycobiome, in 66 patients with alcohol use disorder (AUD) and after 2 weeks of alcohol abstinence using internal transcribed spacer 2 (ITS2) amplicon sequencing of fecal samples.

RESULTS: Patients with AUD had significantly increased abundance of the genera

CONCLUSION: In conclusion, improved liver health in AUD patients after alcohol abstinence was associated with lower intestinal abundances of
