Knowing about liver damage at an early stage allows you to make decisions that will help your liver to recover. Even if you are worried your liver may already be damaged, finding out for sure means you can get any help or treatment you need. Innate immunity is the first line of antiviral protection in the liver. HCV commandeers this line of defense, and ethanol metabolism potentiates its takeover. For example, activation of antiviral IFNβ production in liver cells occurs via the interferon regulatory factor 3 pathway, which requires participation of a protein called mitochondrial antiviral signaling protein (MAVS). HCV evades this innate-immunity protection by cleaving MAVS (Gale and Foy 2005), and ethanol metabolism further enhances this cleavage.
Alcoholic Hepatitis vs. Viral Hepatitis
Further treatment for liver failure also depends on the underlying cause and whether it’s a chronic or acute case. For example, you may need antiviral medications to treat hepatic-injuring viruses in acute liver failure. Since your liver is also responsible for multiple functions in the body, there are key signs and symptoms that you and a doctor may be able to identify if you’ve developed liver failure. Other medicines that can be used to treat liver disease and its complications include antibiotics and heart medicines, like beta blockers.

There are multiple mechanisms by which alcohol potentiates HCV-infection pathogenesis. For example, HCV proteins induce oxidative stress by binding to the outer membranes of mitochondria, stimulating electron transport and increasing the generation of cellular ROS (e.g., superoxide) (Otani et al. 2005). Ethanol-induced oxidative stress also causes mutations in the HCV genome that increase resistance to interferon (IFN) treatment, the former standard of care for HCV (Seronello et al. 2011). Only 9 percent of HCV-infected people with alcohol use disorder respond to IFNα therapy.

What are the complications of end-stage liver disease?
- Keeping up with your regular healthcare checkups can also help catch liver disease sooner rather than later.
- Often, cirrhosis shows no signs or symptoms until liver damage is extensive.
- This is managed by your transplant specialist or hepatologist.
Following hepatic injury, HSCs undergo a complex activation process involving numerous signaling molecules that is characterized by loss of retinoids, increased proliferation, contractility, and chemotaxis. These activated cells are the principal cell source of increased and irregular deposition of extracellular matrix components, which characterize fibrosis. Hepatic stellate cells (HSCs) are key players in the development of fibrosis. HSCs normally reside in the space of Disse as quiescent, lipid (retinyl-ester)-storing cells. Chronic ethanol consumption initiates a complex activation process that transforms these quiescent HSCs into an activated state.
Drinking large amounts of alcohol keeps people from being hungry. Someone with decompensated cirrhosis may develop ascites (or fluid in the abdomen), gastrointestinal bleeding, and hepatic encephalopathy, in which the brain is affected. People who have developed alcohol-related hepatitis and alcohol-related cirrhosis alcoholic liver disease are often malnourished, which can lead to worse health outcomes. Therefore, it’s vital for those with any stage of ALD to maintain a healthy diet. People with signs of malnourishment may need to increase the number of calories and amount of protein they consume, as well as take nutrient or vitamin supplements.
- People who have progressed to alcoholic hepatitis or cirrhosis most likely will not be able to reverse the disease.
- If you’d like to learn even more about cirrhosis, watch our other related videos or visit mayoclinic.org.
- Medications for liver disease or liver failure depend on the underlying cause.
- If done for other reasons, abdominal ultrasonography or CT may suggest hepatic steatosis or show splenomegaly, evidence of portal hypertension, or ascites.
