Diagnosis and Treatment of Alcoholic Liver Disease and Its Complications PMC

For example, SBP patients may have confusion, changes in kidney function, poorly controlled ascites, or overall progressively deteriorating health. Despite the fact that more than half of the patients with SBP complain of some degree of abdominal pain or discomfort, the physical exam alcoholic liver disease of the abdomen usually is completely benign. Patients who have low protein concentrations in the ascites (less than 1.5 g/dl) are at higher risk of developing SBP. Once a patient has had an episode of SBP, there is a 7 in 10 chance that a new episode will occur within the next year.

A subsequent Cochrane review of SAM and ALD could not find evidence supporting or refuting the use of SAM for patients with ALD [Rambaldi et al. 2007]. Most of the data regarding nutritional therapy and ALD pertain to inpatients with alcoholic hepatitis. Some of the most important of these data came from the Veterans Administration Cooperative Studies Program [Mendenhall et al. 1995a, 1995b, 1993, 1986, 1985, 1984]. In this group of studies (which includes over 600 patients with ALD), PCM was demonstrated to be present in virtually all patients with severe ALD. The degree of malnutrition correlated with the development of serious complications such as encephalopathy, ascites and hepatorenal syndrome.

Diagnosis and Treatment of Alcohol‐Associated Liver Disease: A Patient‐Friendly Summary of the 2019 AASLD Guidelines

Documentation of daily caloric intake is necessary for patients with alcoholic hepatitis, and nutritional supplementation (preferably by mouth or nasogastric tube) is an option if oral intake is less than 1200 kcal in a day. The first stage of alcoholic liver disease is hepatic steatosis, which involves the accumulation of small fat droplets under liver cells approaching the portal tracts. More advanced disease is characterized by marked steatosis, hepatocellular necrosis, and acute inflammation, known as alcoholic hepatitis. There is a need for more effective treatment of alcoholic liver disease as the severe form of the disease is life-threatening.

  • For the optimal assessment of liver fibrosis, it must be appreciated by specific stains, as Masson Trichrome or Sirius Red.
  • There is a clear need for clinical trials combining psychosocial and pharmacological interventions in ALD patients with AUD.
  • A large obstacle in making the diagnosis of alcohol abuse is patient reluctance to openly share a drinking history if it may be viewed as excessive or problematic.
  • People who don't stop drinking are likely to have some life-threatening health problems.
  • Of interest, patients with alcohol withdrawal syndrome (AWS) may have a higher prevalence of inflammation on liver biopsy than do patients without withdrawal syndrome (29).

Nutritional goals for patients with cirrhosis from ALD are similar to those for all patients with cirrhosis with repletion of vitamin and mineral deficiencies (thiamine, vitamin B12, and zinc) common in AUD if alcohol use is recent or ongoing (148). This is covered in detail in a subsequent section under the management of AH. Also, even when consuming the same amount of alcohol, women who frequently misuse it are more likely to damage their liver than men.

This pressure is transmitted back to the portal vein and onto the veins that form it. Because of the high pressure on the veins forming the portal vein and the portal vein itself, blood tries to escape, forming new collateral veins (i.e., the increased pressure causes very small varices to grow larger). Many of these veins are localized superficially inside the esophagus and the upper part of the stomach. When these veins engorge because of increased pressure, they are called varices. Hepatorenal syndrome is thought to result from a severe contraction of the artery that feeds the kidney, which may occur as a response to excessive relaxation of the vessels in the rest of the body and a relatively low volume of blood inside the vascular system.

Ethyl glucuronide, a conjugated ethanol metabolite, is detected in urine several days after drinking and can be used reliably in regular drinkers(11). Increased serum liver enzymes, alanine transaminase (ALT), aspartate transaminase (AST) and gamma-glutamyl transferase (GGT), are markers of inflammation and oxidative stress, and have low specificity for detecting alcohol use. Moderate drinking may cause elevations in liver enzymes in obese but not normal weight individuals(13); notably, ALT is more sensitive to BMI and GGT to alcohol consumption. Phosphatidylethanol is an abnormal phospholipid generated from phosphatidylcholine in the presence of ethanol and is positive in blood more than 2 weeks after ethanol is cleared from the body(16). It is more sensitive than ethyl glucuronide for identification of current drinking(12) and is more sensitive compared to GGT and CDT(17).

Possible Complications

The CAGE is short, may be easily implemented in primary care settings and assesses consequences of drinking. The latter makes it less sensitive as a screening tool for at-risk drinking and gives inconsistent results across different ethnicities(7). The AUDIT actually quantifies alcohol consumption and has been validated across different ethnicities(7). There is a brief version of the AUDIT, developed for use in primary care settings(8). The development of liver disease from alcohol ingestion is dependant on several factors.

Because the liver is primarily responsible for alcohol metabolism, it is especially vulnerable to alcohol-related injury. Gut-derived microbial LPS, a component of the outer wall of gram-negative bacteria, has been known as a central role in the pathogenesis of ALD[126,127]. Alcohol has been known to disrupt the gut barrier function, consequently, promotes the translocation of microbial LPS from the lumen of the intestines to the portal vein, where it travels to the liver. In the Kupffer cell, LPS binds to CD14, which combines with toll-like receptor 4, ultimately activating multiple pro-inflammatory cytokine genes[128].

In human studies of alcoholic hepatitis and cirrhosis, abnormal hepatic gene expression in methionine and glutathione metabolism occurs and often contributes to decreased hepatic S-adenosylmethionine (SAM), cysteine, and glutathione levels [Lee et al. 2004]. Rodent and primate studies demonstrate that SAM depletion occurred in early stages of fatty liver infiltration in ALD and decreased SAM concentration, liver injury and mitochondrial damage can be reversed with SAM supplementation [Lieber, 2002]. S-adenosylmethionine appears to attenuate oxidative stress and hepatic stellate cell activation in an ethanol-LPS-induced fibrotic rat model [Karaa et al. 2008]. Most importantly, a randomized, double-blind trial was performed in 123 patients with alcoholic cirrhosis treated using SAM (1200 mg/day, orally) or placebo for 2 years.

With every episode, 2 to 3 of every 10 patients will die from complications of the infection, and only 3 of every 10 are expected to survive for 2 years (Garcia-Tsao 2001). Enteral nutrition is desired over parenteral nutrition because of cost, risk of sepsis of the parenteral nutrition line, preservation of the integrity of the gut mucosa, and prevention of bacterial translocation and multiple organ failure[46]. Moreover, total parenteral nutrition can, in some instances, cause liver disease as one of its complications. We recognise that the UK Biobank cohort is known to be healthier on average than the general UK population [41, 42], meaning that the rates of incident disease observed in the current study are likely to be lower than the UK average incidence rates [43]. Similarly, while this study found significant differences in the outcome rates overall, the exact size of any effects would need to be validated in a nationally representative cohort. But if you must, drink in moderation and have two to three alcohol-free days each week.

The NHS Health Check is a preventive programme in the UK designed to screen for cardiovascular risk and to aid in primary disease prevention. Despite its widespread implementation, the effectiveness of the NHS Health Check for longer-term disease prevention is unclear. In this study, we measured the rate of new diagnoses in UK Biobank participants who underwent the NHS Health Check compared with those who did not. Alcoholic liver disease is treatable if it is caught before it causes severe damage.
