Alcohol-Related Liver Disease

More Content

Chronic alcohol consumption is a major cause of liver cirrhosis which, however, develops in only a minority of heavy drinkers. The contribution of genetic factors to the development of diseases may be investigated either by means of animal experiments, through linkage studies in families of affected patients, or population based case—control studies.

Back to Alcohol-related liver disease. When the liver becomes severely scarred, it's harder for blood to move through it. This leads to an increase in the pressure of blood around the intestines. The blood must also find a new way to return to your heart.

It does this by using smaller blood vessels. But these vessels are not designed to carry the weight of blood, so they can become stretched out and weakened. These weakened blood vessels are known as varices. Alternatively, the bleeding can be rapid and massive, causing you to vomit blood and pass stools that are very dark or tar-like. A tiny band can then be used to seal the base of the varices. This fluid is known as ascites. Initially, this can be treated with water tablets diuretics.

If the problem progresses, many litres of fluid can build up, which needs to be drained. This is a procedure known as paracentesis and involves a long, thin tube being placed into the fluid through the skin under local anaesthetic.

One of the problems associated with the development of ascites is the risk of infection in the fluid spontaneous bacterial peritonitis. This is a potentially very serious complication and is linked to an increased risk of kidney failure and death. In hospital, body functions are supported and medicine is used to remove toxins from the blood.

This can make the body more vulnerable to infection, particularly urinary infections and respiratory infections such as pneumonia. Over the past few decades, rates of liver cancer in the UK have risen sharply due to increased levels of alcohol misuse.

A high level of toxins in the blood due to liver damage is known as hepatic encephalopathy. Infection Damage to the liver can weaken the immune system.

Alcohol-Related Liver Disease

The liver is a large organ with an important job in your body. It filters the blood of toxins, breaks down proteins, and creates bile to help the body absorb fats. Doctors call this condition alcoholic liver cirrhosis. As the disease progresses, and more of your healthy liver tissue is replaced with scar tissue, your liver will stop functioning properly. According to the American Liver Foundation , between 10 and 20 percent of heavy drinkers will develop cirrhosis. The disease is part of a progression. It may start with fatty liver disease, then progress to alcoholic hepatitis, and then to alcoholic cirrhosis.

The journal's aim is to publish articles focused on basic, clinic care and translational research that seeks to prevent rather than treat the complications of endstage liver disease. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years. CiteScore measures average citations received per document published. Read more. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact.

Alcoholic liver disease ALD , also called alcohol-related liver disease ARLD , is a term that encompasses the liver manifestations of alcohol overconsumption, including fatty liver , alcoholic hepatitis , and chronic hepatitis with liver fibrosis or cirrhosis. It is the major cause of liver disease in Western countries. Although steatosis fatty liver disease will develop in any individual who consumes a large quantity of alcoholic beverages over a long period of time, this process is transient and reversible. The mechanism of ALD is not completely understood. Chronic consumption of alcohol results in the secretion of pro-inflammatory cytokines TNF-alpha , Interleukin 6 [IL6] and Interleukin 8 [IL8] , oxidative stress , lipid peroxidation , and acetaldehyde toxicity.

Alcohol consumption is high in most Western countries. The male:female ratio is about Disorders that occur in alcohol abusers, often in sequence, include.

Excessive alcohol consumption is a global healthcare problem. The liver sustains the greatest degree of tissue injury by heavy drinking because it is the primary site of ethanol metabolism. Steatosis is the earliest response to heavy drinking and is characterized by the deposition of fat in hepatocytes. Steatosis can progress to steatohepatitis, which is a more severe, inflammatory type of liver injury. This stage of liver disease can lead to the development of fibrosis, during which there is excessive deposition of extracellular matrix proteins.

Malnutrition encompassing both macro- and micro-nutrient deficiency, remains one of the most frequent complications of alcohol-related liver disease ArLD. Protein-energy malnutrition can cause significant complications including sarcopenia, frailty and immunodepression in cirrhotic patients. Moreover, nutritional deficit increases the likelihood of hepatic decompensation in cirrhosis.
