Fecal Microbiota Transplantation in Severe Alcoholic Hepatitis- Assessment of Impact on Prognosis and Short-term Outcome

Overview

Alcoholic liver disease has become one of the foremost causes of chronic liver disease across the world, and a cause of considerable morbidity and mortality. Alcoholic steatohepatitis is an entity in this broad spectrum, with severe alcoholic hepatitis transitioning to acute on chronic liver failure carrying a one month mortality of as high as 20 to 50%. The current management guidelines for severe alcoholic hepatitis show benefit with prolonged alcohol abstinence, nutritional support, the use of corticosteroids, pentoxifylline or N-acetyl cysteine (NAC) and early liver transplantation. However, major studies and meta-analyses have demonstrated that these interventions, with the exception of early liver transplantation, do not improve mortality rates to the level of statistical significance. Owing to the high short term mortality associated with severe alcoholic hepatitis, the inadequacy of a treatment that could significantly impact this short term mortality, and the limited applicability of early liver transplantation, a study on newer modalities of treatment is warranted. The role that human gut microbiota plays in health and disease is receiving considerable attention. Targeting intestinal dysbiosis, a phenomenon found to be intricately linked with the causation of alcoholic hepatitis, could provide insights into novel therapeutic strategies. Fecal microbiota transplantation is a novel approach that has gained widespread acceptance in in the management of recurrent severe Clostridium difficile infection. It's role is also being studied in other diseases where an association with gut dysbiosis has been found, such as in inflammatory bowel disease and irritable bowel syndrome. The role of FMT has also been studied in liver diseases such as non-alcoholic fatty liver disease (NAFLD), liver cirrhosis and primary sclerosing cholangitis. In this process, a diseased recipient is transferred fecal material containing the microflora of a healthy individual. It limits the colonization of pathogens, inducing colonization resistance, affects microbiota composition in the gut, as well as metabolism in the microbial pathogens. FMT helps alleviate gut dysbiosis and restores gut microbial diversity. Our aim is to evaluate the role of FMT on short term survival and improvement in scores of prognostic significance (CTP, MELD, MELDNa, mDF) in patients with severe alcoholic hepatitis.
