Changes in gUt micRobiota After Enteral Feeding (in Alcoholic Hepatitis)

Drinking large amount of alcohol can cause damage to the liver. If the liver is severely injured by alcohol it can become very inflamed and this condition is called alcoholic hepatitis. Alcoholic hepatitis can be life threatening. There is no cure for alcoholic hepatitis. It is known that stop drinking and have good nutrition can help the liver to recover. Infections are very common for people who suffer from alcoholic hepatitis. Sometimes these infection can be very severe. It is not always possible to find out where the infection is coming from. But the bacteria living in the bowel may move to other organs causing these infections and an illness like alcoholic hepatitis can cause "bad bacteria" to take over from "good bacteria" in the gut. This study wants to understand the changes in the bacteria in the bowel of people who have an acute inflammation of the liver cause by alcohol (alcoholic hepatitis). The investigators will take stool samples from patients admitted in the hospital with alcoholic hepatitis. The investigators will run tests on the stools that can find out which bacteria live in the bowel. Its is expected to find these bacteria to be different from the ones living in the bowel of healthy people. The investigators are interested to see if these bacteria change once the patients are given good nutrition using a small tube from the nose to the stomach. This type of nutrition is used routinely to help improve the liver in severe alcoholic hepatitis. The investigators will take some more stool sample from these patients after the nutrition through the tube has started to check how the bacteria change with nutrition. Better tools to check the bacteria in the bowel are now available so this can help the investigators to understand better if changing bacteria in the bowel can help recovery in alcoholic hepatitis.
