Gut microbiota and hepatitis-B-virus-induced chronic liver disease: implications for faecal microbiota transplantation therapy.

Abstract

Hepatitis B is one of the most common infectious diseases globally. It has been estimated that there are 350 million chronic hepatitis B virus (HBV) carriers worldwide. The liver is connected to the small intestine by the bile duct, which carries bile formed in the liver to the intestine. Nearly all of the blood that leaves the stomach and intestines must pass through the liver. Human intestines contain a wide diversity of microbes, collectively termed the 'gut microbiota'. Gut microbiota play a significant role in host metabolic processes and host immune modulation, and influence host development and physiology (organ development). Altered gut microbiota is a common complication in liver disease. Changes in intestinal microbiota seem to play an important role in induction and promotion of HBV-induced chronic liver disease progression, and specific species among the intestinal commensal bacteria may play either a pathogenic or a protective role in the development of HBV-induced chronic liver disease. Thus, the gut microbiome may represent fertile targets for prevention or management of HBV-induced chronic liver disease. Faecal microbiota transplantation (FMT) may be a useful therapy for HBV-related disease in the future. However, the data available in this field remain limited, and relevant scientific work has only just commenced. New technologies have enabled systematic studies of gut microbiota, and provided more realistic information about its composition and pathological variance. This review summarizes the cutting edge of research into the relationship between gut microbiota and HBV-induced chronic liver disease, and the future prospects of FMT therapy.
