Present and future of fecal microbiome transplantation in cirrhosis.

Over the last few decades, there have been tremendous advances in our understanding of the role of the gut microbiome in cirrhosis and the clinical sequelae that follow. Progressive dysbiosis and immune dysregulation occur in patients with cirrhosis. In fact, alterations in the gut microbiome occur long before a diagnosis of cirrhosis is made. Understandably, our attention has recently been diverted toward potential modulators of the gut microbiome and the gut-liver axis as targets for treatment. The goal of this review is to highlight the utility of manipulating the gut microbiome with a focus on fecal microbiome transplantation (FMT) in patients with cirrhosis. In addition, we will provide an overview of disease-specific microbial alterations and the resultant impact this has on cirrhosis-related complications.
