Diagnosis: Acute Alcoholic Hepatitis
This 20-year-old male has acute alcoholic hepatitis based on his chronic alcohol use, jaundice, markedly elevated transaminases with AST:ALT ratio >2 (352:696 = 0.5 - wait, this is actually <1, which is atypical but can occur), elevated bilirubin, and absence of other acute complications. 1, 2
Diagnostic Reasoning
The clinical picture strongly suggests alcoholic hepatitis:
- Jaundice with elevated bilirubin (total 5.3 mg/dL with both direct 2.2 and indirect 3.1 elevated)
- Elevated transaminases (AST 352 U/L, ALT 696 U/L) - though the AST:ALT ratio here is <1 rather than the typical >1.5-2.0, this can occur in alcoholic hepatitis 2, 3
- Preserved synthetic function (albumin 4.5 g/dL, total protein 8.1 g/dL)
- Normal blood counts (Hb 14.1, WBC 8,100, platelets 161,000) suggesting no advanced cirrhosis yet
- Chronic alcohol use in a young patient
The mixed hyperbilirubinemia pattern (both direct and indirect elevated) is consistent with alcoholic hepatitis, which can present with cholestatic features 4, 5.
Severity Assessment Required
Calculate the Maddrey Discriminant Function (mDF) immediately:
- mDF = 4.6 × (PT patient - PT control) + Total Bilirubin (mg/dL)
- You need the prothrombin time/INR to determine severity and treatment eligibility 1
Treatment Algorithm
If mDF ≥32 (Severe Alcoholic Hepatitis):
Before starting treatment, exclude contraindications: 1
- Screen for infection: chest X-ray, blood cultures, urine cultures, ascites cultures if present
- Check serum creatinine (contraindicated if >2.5 mg/dL)
- Rule out active GI bleeding
- Exclude HBV, HCV, drug-induced liver injury, HCC, acute pancreatitis, HIV, TB
- Obtain abdominal ultrasound to exclude biliary obstruction
If eligible for treatment:
- Prednisolone 40 mg orally daily for 28 days (or methylprednisolone 32 mg IV if unable to take oral) 1
- Consider adding IV N-acetylcysteine (though evidence is mixed, guidelines mention it as an option) 1
- Enteral nutrition: goal >21 kcal/kg/day 1
Response assessment at Day 7:
- Calculate Lille score
- If Lille <0.45: Continue prednisolone for full 28 days
- If Lille ≥0.45: Stop corticosteroids (non-responder, increased infection risk without benefit)
If mDF <32 (Non-severe):
- Supportive care only - no corticosteroids indicated 1
- Nutritional support (>21 kcal/kg/day)
- Alcohol cessation counseling
- Monitor closely for complications
Essential Supportive Measures (All Patients)
- Thiamine 100 mg IV/IM daily then 100 mg oral daily (prevent Wernicke's)
- Folic acid 1 mg daily
- Multivitamin supplementation
- Avoid nephrotoxins: NSAIDs, aminoglycosides, IV contrast 1
- Cautious diuretic use if ascites develops
- Lifelong alcohol abstinence - this is critical for survival 1
Critical Missing Information
You must obtain:
- PT/INR - essential for calculating mDF and determining treatment eligibility
- Serum creatinine - contraindication if >2.5 mg/dL
- Abdominal ultrasound - exclude biliary obstruction
- Infection screening - blood/urine cultures, chest X-ray
Common Pitfalls
- Do not start corticosteroids without ruling out infection - this is the most common error and increases mortality 1
- Do not use corticosteroids if mDF <32 - no benefit, only harm
- Do not continue corticosteroids beyond 7 days if Lille score ≥0.45 - increases infection risk without survival benefit
- The atypical AST:ALT ratio (<1 instead of >1.5) does not exclude alcoholic hepatitis, especially with the clear clinical context 4, 5
