The cohort randomly received either a placebo or active FMT gathered from a single donor high in Lachnospiraceae and Ruminococcaceae, two types of gut bacteria seen in low levels in AUD patients. “We conclude in this Phase 1 trial that FMT in men with cirrhosis is safe, associated with reduction in short-term craving and consumption with beneficial microbial change,” the researchers wrote in the conclusion to the study reporting preliminary data in 2020.
