Alteration of the normal gut-liver axis is important in primary sclerosing cholangitis (PSC). Lack of effective medical therapy for PSC makes microbiome restoration an alluring therapeutic target. Allegretti et al. performed an open-label safety trial of fecal microbiota transplant (FMT) in noncirrhotic PSC patients with inflammatory bowel disease in remission on minimal therapy. FMT was safe in this population, and after FMT, there was a stable, early increase in microbial diversity and donor engraftment with mixed effects on alkaline phosphatase but no significant change in fecal bile acid profile. Further trials are needed to find whether FMT has a role to play in PSC therapy.
