Abstract

Alcohol-induced gut microbiota (GM) alterations are linked to alcohol use disorder (AUD) pathogenesis. Healthy donor stool transplant (fecal microbiota transplant [FMT]) reduced alcohol desire and improved clinical outcomes in small animal and human studies. Baseline and post-therapy-related GM changes in a real-world cohort with severe alcohol-related liver disease and AUD, patterns of drinking, and relapse have not been studied. We prospectively analyzed retrospective clinical data and stored samples to examine GM alterations in a cohort of severe alcohol-associated hepatitis (SAH) patients who underwent FMT or corticosteroid treatment followed for at least 12 months. The GM changes at baseline in the context of a pattern of drinking (binge vs. every day) and baseline and post-treatment alcohol relapse status (relapser vs. non-relapser). We identified 28 patients on FMT and 25 on corticosteroids who survived 1 year post-treatment. After necessary exclusions, the final cohort for various grouped GM analysis included 16 patients in the FMT arm and 14 on corticosteroids. Pedobacter and Streptophyta species at the commencement of treatment predicted alcohol relapse in steroid-ineligible patients receiving FMT and steroid-treated patients, respectively. At 6–12 months post-FMT, non-relapsers had elevated short-chain fatty acid-producing bacterial taxa linked with lower alcohol cravings. Alcohol relapse was significantly more in those on steroid therapy and was associated with the upregulation of the nucleotide metabolism pathway related to ethanol metabolism. We demonstrate pertinent baseline and post-treatment intestinal bacterial alterations that impact patterns of AUD patterns and relapse in SAH patients in the context of the therapy offered.
