Background

Acute alcoholic hepatitis is inflammatory liver disease secondary to alcohol use.

  • spectrum from hepatic steatosis to alcoholic hepatitis to cirrhosis
  • history of (usually chronic) alcohol abuse (~80 grams of ethanol daily for 5 years)
  • ranges from subclinical cases to severe multisystem dysfunction

Clinical Features

Symptoms

  • abdominal pain
  • N/V
  • weight loss / fatigue / anorexia

Signs

  • RUQ tenderness
  • jaundice
  • fever
  • hepatomegaly
  • ascites
  • encephalopathy
  • spider angioma
  • GI bleed/varices
  • malnutrition
  • symptoms of alcohol withdrawal

Cirrhosis is found in 50-60% of cases of alcoholic hepatitis (4).

Differential Diagnosis

Diagnosis

Diagnosis is difficult and relies on a good history (1).

  • History of significant alcohol intake
  • Clinical evidence of liver disease
  • Supporting laboratory abnormalities
    • May be nondiagnostic in patients with mild disease or early cirrhosis

Work Up

Labs

  • CBC
    • Leukocytosis with elevated ANC
  • Chemistry including magnesium and phosphate
  • LFTs
    • Elevated AST/ALT (characteristically >2:1 and < 500 IU/L)
    • GGT alone is less reliable (low sensitivity and specificity (1))
  • Coagulation factors
    • Elevated PT/INR
  • Lipase if suspect pancreatitis
  • Consider hepatitis panel

Imaging

Consider transabdominal ultrasound if concern for:

  • Biliary obstruction
  • Budd-Chiari syndrome
  • Hepatic or biliary neoplasms

Management

  • Control of withdrawal symptoms
  • Nutritional support for malnutrition: especially thiamine, folate, pyridoxine, magnesium, phosphate, glucose, and protein

High risk, severe cases

  • Steroids
  • Pentoxifylline

Prognosis

  • Maddrey Discriminant Function score (MDF)
  • Model for End-Stage Liver Disease score (MELD)
  • High risk: MDF ≥ 32, MELD ≥ 18, or presence of hepatic encephalopathy (1)

Disposition

  • Discharge
    • Mild disease/low risk
    • Nutritional assessment and intervention
    • Discuss alcohol use and recommend strict abstinence
  • Admit
    • High risk defined as MDF ≥ 32, MELD ≥ 18, or presence of hepatic encephalopathy
