The ELF also demonstrated superior fibrosis discrimination ability compared with different biological tests, such as the AST to platelet ratio index (APRI) or fibrosis-4 (FIB-4) index 176,177. In summary, a combination of non-invasive diagnostic tests with serum-based fibrosis biomarkers will likely emerge as the mainstay diagnostic tool in the future 136. The first and the main pathway is hepatocyte cytoplasmic alcohol dehydrogenase (ADH), which uses nicotinamide adenine dinucleotide (NAD+) as a co-factor and oxidizes ethanol to acetaldehyde, which is highly toxic and causes DNA synthesis impairment 8. It is noteworthy that CYP2E1 only catalyzes approximately 10% of ethanol into acetaldehyde under normal physiological conditions; however, it becomes more prominent in chronic alcohol consumption due to enhanced CYP2E1 expression 8,9. The third and more minor pathway is via the heme-containing catalase in the peroxisomes, which can also oxidize ethanol to acetaldehyde 22. The enzyme aldehyde dehydrogenase (ALDH) is located in the hepatocyte mitochondria and further oxidizes acetaldehyde to acetate, which is released into the circulation system and is further oxidized to carbon dioxide in various extrahepatic tissues 9.
Medical Professionals
EtG can be detected in the urine or hair, has a much longer detection window, and a higher specificity than CDT, although biological variability (e.g., medications and foods) still exists and may complicate the interpretation of the results 157,158. Several studies have compared the detection ability of these biomarkers and revealed conflicting results 154,157,159,160. It is proposed that the combination of these biomarkers, such as EtS in urine, FAEEs in hair, and PEth in serum, may improve the overall sensitivity and specificity and provide more reliable results 154. Recently, the differential methylation of DNA in specific genes revealed its potential utility as a diagnostic marker of active alcohol consumption, and may provide another choice in molecule-based studies in ALD 161,162. Clinicians should screen all patients for harmful patterns of alcohol use. All patients with alcohol-related liver disease should abstain from alcohol.
What is the outlook for people with alcohol-related liver disease?
- If iron has accumulated in the liver or if people have had hepatitis C for more than 6 months, the risk of liver cancer (hepatocellular carcinoma) is increased.
- People who have developed alcohol-related hepatitis and alcohol-related cirrhosis are often malnourished, which can lead to worse health outcomes.
- The Keap-1/Nrf-2/HO-1 antioxidative pathway plays a vital role, as the activation of Nrf-2 leads to the upregulation of HO-1 and various other antioxidant enzymes, thereby augmenting the liver’s antioxidant capacity 16,17.
Gut-liver axis is crucial in the etiology of alcoholic liver disease. Studies indicate that COS play a significant role in regulating the gut microbiome. They facilitate the alcoholic liver disease proliferation of beneficial bacteria, such as Bifidobacterium and Lactobacillus, while restrain the increase of harmful bacteria, such as Escherichia coli, thereby enhancing the stability and diversity of gut microbiome.
Deterrence and Patient Education
Different types of beverages contain different percentages of alcohol. Alcoholic liver disease is treatable if it is caught before it causes severe damage. The chances of getting liver disease go up the longer you have been drinking and more alcohol you consume.
Possible Complications
To diagnose ALD, a healthcare provider will assess alcohol use, ask about symptoms, and conduct several tests. An assessment of alcohol use will establish when alcohol consumption started, how much a person drinks, and how often. Screening for liver disease typically starts with blood tests that check liver biochemistries, or tests of the liver function, says Lindenmeyer. These tests are often part of routine blood tests given during a physical exam. If the results are abnormal, more targeted blood tests may be performed to look for specific liver diseases such as hepatitis.
Food, Drink, and Your Liver
Insights drawn from Figure 8b reveal that the liver index in MOD exhibited an obvious increase compared to that of CON. Additionally, within the MOD group, the liver indices for all doses of COSs demonstrated a marked reduction. Notably, the liver index in both high-dose groups of COSs approached those observed in the group treated with Bifendate. Sherman and Martinez, who are collecting data about HALT’s effectiveness, have jointly treated more than 300 patients since its launch two years ago. Patients are referred to HALT by primary care physicians and gastroenterologists. All HALT patients are also offered an optional visit with Triveni Defries, MD, an addiction medicine expert who, if needed, can prescribe medications to control patients’ cravings and withdrawals.
Complications
- All patients should therefore be screened for alcohol abuse or dependency.
- When the body can compensate and manage cirrhosis, the typical lifespan is 6–12 years.
- Numerous studies have revealed that alcohol consumption is correlated with iron overload and hepcidin synthesis downregulation in Kupffer cells and hepatocytes in the liver, while hepcidin was proposed as a key mediator in iron homeostasis 37,38.
Also, the liver can function normally even when about 80% of it is damaged. However, if people continue to drink alcohol, liver damage progresses and may eventually result in death. As emphasized in the most recent national practice guidelines, health care providers must be attentive Alcohol Use Disorder for signs of covert alcohol abuse.18 Many patients do not openly disclose an accurate history of alcohol use. In addition, no physical examination finding or laboratory abnormality is specific for ALD. All patients should therefore be screened for alcohol abuse or dependency.
Alcohol-Related Liver Disease: Basic Mechanisms and Clinical Perspectives
Doing so reduces the number of new liver cells killed from alcohol use and gives your liver a chance to regenerate itself. You’ll only be considered for a liver transplant if you have developed complications of cirrhosis despite having stopped drinking. A liver transplant may be required in severe cases where the liver has stopped functioning and does not improve when you stop drinking alcohol. To be considered for a liver transplant, patients must remain abstinent from alcohol prior to transplantation surgery. The purpose of this is to ensure that patients are able to maintain abstinence and are likely to remain abstinent after the transplant surgery.
