alcoholic hepatitis

Alcoholic hepatitis, also known as alcoholic liver disease (ALD), is a condition where inflammation and damage occur in the liver due to excessive alcohol consumption.

Causes and Risk Factors

• Drinking too much alcohol overloads the liver with toxins that injure the tissues [1].
• Long-term heavy intake of ethanol can lead to progressive inflammatory liver injury [9].

Symptoms and Complications

• Alcoholic hepatitis is characterized by rapid onset of jaundice, malaise, tender hepatomegaly (enlarged liver), and elevated liver enzymes [2].
• People with alcohol-associated acute hepatitis or cirrhosis often develop kidney problems, gastrointestinal bleeding, fluid in the belly, confusion, and other complications [4].

Characteristics

• Alcoholic hepatitis is a distinct clinical syndrome caused by chronic alcohol abuse [6].
• It carries a particularly poor prognosis with a 28-day mortality ranging from 30% to 50% [6].
• Alcoholic hepatitis is unrelated to infectious hepatitis and can be caused by alcohol misuse over a longer period [7].

Other Information

• Acute hepatitis resulting from ingestion of alcohol can also occur, leading to liver damage and potentially life-threatening complications [10].

Alcoholic hepatitis, also known as alcoholic liver disease (ALD), can manifest in various ways, depending on its severity. Here are the common signs and symptoms:

• Mild or early stages: In some cases, people with mild or early alcoholic hepatitis may not experience any noticeable symptoms at all [1]. However, as the condition progresses, individuals may start to notice:
  • Tenderness or soreness in the upper right abdomen, where the liver is located [3].
  • Visibly swollen or enlarged liver [3].
• Moderate stages: As alcoholic hepatitis advances, symptoms can become more pronounced and include:
  • Fatigue
  • Nausea
  • Upper-right abdominal pain
  • Jaundice (yellowing of the skin and eyes) [11]
• Severe stages: In severe cases, symptoms can be life-threatening and may include:
  • Fluid buildup in the belly (ascites)
  • Confusion or altered mental state due to liver failure
  • Gastrointestinal bleeding
  • Liver cancer
  • Severe infections [5]

It's essential to note that these symptoms can vary between individuals, and some people may not experience any noticeable signs at all. If you suspect someone has alcoholic hepatitis, it's crucial to seek medical attention promptly.

Diagnostic Tests for Alcoholic Hepatitis

Alcoholic hepatitis can be diagnosed using various tests, which help healthcare professionals assess the severity of liver inflammation and damage.

• Blood Tests: These include:
  • Liver enzymes (AST and ALT) to check if the liver is working properly [8]
  • Serum AST/ALT ratio to evaluate liver function [9]
  • Blood clotting tests to confirm the diagnosis of alcoholic hepatitis [10]
• Imaging Tests: These may be ordered to assess liver damage and inflammation:
  • Ultrasound, which can help exclude gallstones and other biliary tract issues [6]
• Liver Biopsy: This is a more invasive test that involves taking a small sample of liver tissue for examination under a microscope. It's usually performed when blood tests and imaging tests are inconclusive or to assess the severity of liver damage.

It's essential to note that a complete physical exam, including questions about alcohol use, is also part of the initial evaluation process [1]. A healthcare professional will consider these diagnostic tests in conjunction with medical history and physical examination findings to make an accurate diagnosis.

Alcoholic hepatitis can be challenging to treat, but various medications have been shown to be effective in managing the condition.

Corticosteroids: Corticosteroids, such as prednisolone, are often used to reduce inflammation and swelling in the liver. These medications can help improve liver function and reduce symptoms like jaundice and fatigue [1][2].

Vitamin supplements: Vitamin deficiencies, particularly thiamine (vitamin B1) and folate, are common in people with alcoholic hepatitis. Supplementing these vitamins can help alleviate symptoms and support liver health [3].

Antioxidants: Antioxidant medications, such as silymarin, have been shown to reduce oxidative stress and inflammation in the liver, which can help improve liver function and overall health [4][5].

Other treatments: In some cases, other medications like pentoxifylline may be used to treat alcoholic hepatitis. These medications work by reducing inflammation and improving blood flow to the liver [6].

It's essential to note that while these medications can be effective in managing symptoms, they should not be considered a substitute for abstinence from alcohol. The most critical aspect of treating alcoholic hepatitis is addressing the underlying issue of excessive alcohol consumption.

Alcoholic hepatitis has several differential diagnoses, which are conditions that can present with similar symptoms and laboratory findings. Some of these differential diagnoses include:

• Alcoholic pancreatitis: This is a condition where the pancreas becomes inflamed due to heavy alcohol consumption. It can present with abdominal pain, nausea, and vomiting, similar to alcoholic hepatitis.
• Gallstones: Gallstones are small, hard deposits that form in the gallbladder and can cause symptoms such as abdominal pain, jaundice, and fever. They can be a differential diagnosis for alcoholic hepatitis, especially if the patient has a history of gallstone disease.
• Budd-Chiari syndrome: This is a rare condition where the hepatic veins become blocked, leading to liver enlargement and ascites (fluid accumulation in the abdomen). It can present with similar symptoms to alcoholic hepatitis, such as abdominal pain, jaundice, and fever.
• Viral hepatitis: Viral hepatitis, particularly hepatitis B and C, can cause inflammation of the liver and present with similar symptoms to alcoholic hepatitis, including fatigue, loss of appetite, and jaundice.
• Drug-induced hepatitis: Certain medications, such as acetaminophen (Tylenol) overdose, can cause liver damage and present with similar symptoms to alcoholic hepatitis.

It's essential to consider these differential diagnoses when evaluating a patient with suspected alcoholic hepatitis. A thorough medical history, physical examination, laboratory tests, and imaging studies can help differentiate between these conditions [3][4].

In one study, clinical diagnosis of alcoholic hepatitis based on history and physical examination (H&P), laboratory results, and imaging was approximately 91% sensitive and 96% specific with 88% positive predictive value (PPV) [7]. This highlights the importance of a comprehensive evaluation in making an accurate diagnosis.

Diagnostic techniques such as ultrasound, CT, and MRI can provide useful information for identifying alcoholic liver disease (ALD) and excluding other causes of liver dysfunction [9].
