Alcoholic Hepatitis Can Still Be Diagnosed 3 Weeks After Last Alcohol Consumption

Yes, a patient who last consumed alcohol 3 weeks ago can still be diagnosed with alcoholic hepatitis. According to the EASL Clinical Practice Guidelines, alcoholic hepatitis is characterized by recent onset of jaundice with or without other signs of liver decompensation in patients with ongoing alcohol abuse, and "it is not uncommon for patients to have ceased alcohol consumption days or weeks before the onset of symptoms" 1.

Diagnostic Criteria for Alcoholic Hepatitis

Alcoholic hepatitis is diagnosed based on:

1. Clinical presentation:

   • Progressive jaundice (cardinal sign)
   • Often accompanied by fever (even without infection)
   • Malaise, weight loss, and malnutrition
   • May include signs of liver decompensation (ascites, encephalopathy)

2. Laboratory findings:

   • Neutrophilia
   • Hyperbilirubinemia (>50 μMol/L)
   • AST >2× upper limit of normal but rarely above 300 IU/ml
   • AST/ALT ratio typically >1.5-2.0
   • In severe cases: prolonged prothrombin time, hypoalbuminemia, decreased platelet count

3. History of heavy alcohol use:

   • The diagnosis requires a history of heavy alcohol consumption
   • No specific threshold has been identified, but generally occurs after decades of heavy use (>80 g/day) 1

Time Course of Alcoholic Hepatitis

The 2018 EASL guidelines explicitly state that patients may have ceased alcohol consumption days or weeks before symptom onset 1. This is critical to understand because:

• The inflammatory process continues despite alcohol cessation
• The clinical syndrome can manifest or worsen even after stopping alcohol
• Recent abstinence does not exclude the diagnosis

Confirmation of Diagnosis

In cases of diagnostic uncertainty, especially when the patient has been abstinent for some time:

• Liver biopsy (preferably transjugular to reduce bleeding risk) can confirm the diagnosis
• Biopsy findings would show steatosis, hepatocyte ballooning, and inflammatory infiltrate with polymorphonuclear neutrophils 1
• Biopsy can also rule out other diagnoses that may present similarly (found in 10-20% of cases) 1

Severity Assessment

If alcoholic hepatitis is diagnosed, severity should be assessed using:

• Maddrey Discriminant Function (mDF ≥32 indicates severe disease)
• MELD score (score >20 indicates severe disease)
• Other scoring systems include GAHS and ABIC 1

Important Considerations

• The diagnosis of alcoholic hepatitis is a clinical syndrome, not just a histological finding
• Symptoms may develop or worsen after alcohol cessation due to ongoing inflammation
• Other causes of liver injury should be excluded (sepsis, drug-induced liver injury, gallstone migration)
• In the absence of liver biopsy, more stringent clinical and laboratory criteria should be applied 1

Treatment Implications

For patients with severe alcoholic hepatitis (mDF ≥32):

• Corticosteroid treatment should be considered
• Systematic screening for infection before starting treatment 1
• Abstinence is essential for long-term survival 1

In conclusion, the 3-week abstinence period does not rule out alcoholic hepatitis. The diagnosis should be based on clinical presentation, laboratory findings, and history of heavy alcohol use, with liver biopsy performed when there is diagnostic uncertainty.
