Quick check
A 46-year-old man with heavy alcohol use has jaundice, tender hepatomegaly, bilirubin 11 mg/dL, AST 168 U/L, ALT 71 U/L, and INR 1.8. Ultrasound shows no biliary obstruction.
Which interpretation best fits this presentation?
Pattern recognition starts the diagnosis; bilirubin, INR, kidney function, infection assessment, and trajectory determine the stakes.
Numbers stratify risk; trajectory decides what to do next
Severity tools organize prognosis but should be interpreted with bleeding, infection, kidney function, and diagnostic certainty.
Current ACG guidance uses MELD above 20 to identify severe alcohol-associated hepatitis for corticosteroid consideration when no major contraindication remains.
A Maddrey discriminant function of at least 32 is a historical severity threshold, but it should not displace MELD, infection assessment, kidney function, or diagnostic certainty.
The Lille score on day 4 or 7 estimates corticosteroid response; a value above 0.45 supports stopping because benefit is unlikely.
Place each quantitative anchor on the clinical-risk continuum.
Fat, active hepatitis, and scar are different clinical states
Alcohol exposure can produce overlapping phenotypes, but each state has a different short-term risk.
Simple steatosis is often asymptomatic and reversible with abstinence; it does not require jaundice or synthetic dysfunction.
Alcohol-associated hepatitis is an acute inflammatory syndrome marked by recent or worsening jaundice, often with tender hepatomegaly, fever, leukocytosis, and impaired synthetic function.
Cirrhosis reflects advanced fibrosis and portal hypertension; a patient may have normal or only mildly abnormal AST and ALT despite major risk.
Compare the defining clinical payoff of each phenotype.
Macrovesicular fat may cause hepatomegaly and mild enzyme abnormalities; abstinence can reverse fat before fibrosis is established.
Clinical syndrome of recent jaundice and liver dysfunction after sustained heavy exposure; infection and competing causes must be assessed.
Advanced scar without current ascites, encephalopathy, or variceal bleeding; surveillance and portal hypertension care are still required.
Ascites, variceal hemorrhage, encephalopathy, or jaundice signals reduced reserve and should trigger transplant consideration.
Normal aminotransferases do not rule out cirrhosis.
Build the diagnosis before reaching for prednisolone
The safe sequence identifies the syndrome, grades severity, and actively searches for treatment hazards.
Confirm alcohol exposure timing and quantify intake without using stigma-laden labels.
Exclude biliary obstruction, viral hepatitis, drug injury, ischemia, and other plausible causes; use biopsy when the diagnosis remains uncertain and would change treatment.
Assess bilirubin, INR or prothrombin time, creatinine, sodium, mental status, infection, gastrointestinal bleeding, and nutrition.
Place the decision steps in order.
Choose the first step.
AST and histology support; they do not certify
Classic clues become dangerous when treated as stand-alone diagnostic tests.
AST commonly exceeds ALT in alcohol-associated hepatitis, often with both below 400 U/L, but the ratio is not specific for alcohol and can change with advanced disease.
Mallory-Denk bodies are damaged keratin aggregates within ballooned hepatocytes. They support steatohepatitis but can occur in metabolic steatohepatitis, cholestatic disease, and other injury.
Aminotransferase magnitude measures hepatocyte leakage, not hepatic reserve; bilirubin, INR, creatinine, and clinical decompensation better express severity.
Select the one statement that remains valid across phenotypes.
Map injury from hepatocyte to whole-patient reserve
The pathology and the bedside findings occupy different levels of the same disease.
Steatosis and ballooning begin in hepatocytes, while neutrophilic inflammation and pericellular fibrosis often cluster in zone 3.
Progressive bridging fibrosis remodels the liver into cirrhosis, raising portal resistance and producing splenomegaly, varices, and ascites.
Extrahepatic danger includes infection, acute kidney injury, sarcopenia, alcohol withdrawal, and malnutrition.
Locate each finding on the disease map.
Steatosis, ballooning degeneration, and Mallory-Denk bodies are cellular injury findings.
Steatohepatitis often begins centrilobularly with chicken-wire pericellular fibrosis.
Cirrhotic resistance drives varices, splenomegaly, and ascites.
Infection, kidney injury, frailty, nutrition, and ongoing alcohol use determine outcomes beyond the biopsy.
Treatment is layered, and steroids belong to a narrow layer
Every patient needs alcohol-use treatment and nutrition; only selected patients with severe hepatitis are corticosteroid candidates.
Use nonjudgmental addiction treatment, pharmacotherapy when appropriate for liver status, and longitudinal relapse prevention. Sustained abstinence is the most important disease-modifying intervention.
Correct protein-calorie and micronutrient deficits; do not routinely restrict protein because sarcopenia worsens outcomes.
Prednisolone 40 mg daily for 4 weeks may be used for severe alcohol-associated hepatitis, generally MELD above 20, after major contraindications are addressed; stop when the day 4 or 7 Lille score is above 0.45.
Reveal what each intervention can and cannot accomplish.
Abstinence care
Improves survival across stages and requires a treatable alcohol use disorder plan, not a one-time instruction.
Pair hepatology with addiction care.
Nutrition
Frequent energy-dense feeding and adequate protein address common catabolism and sarcopenia.
Use enteral support when oral intake is inadequate.
Prednisolone
A 40 mg daily, 4-week course may improve short-term outcomes in carefully selected severe hepatitis; it does not repair established cirrhosis.
Use day 4 or 7 Lille response to avoid futile exposure.
Early transplant evaluation
May be appropriate for selected patients with nonresponse or decompensation after multidisciplinary psychosocial and medical assessment.
Do not apply a rigid sobriety interval as the only criterion.
Stage 1 of 3: Overview
Overview
Alcohol-Associated Liver Disease
The safe sequence identifies the syndrome, grades severity, and actively searches for treatment hazards.
Step by step
Build the diagnosis before reaching for prednisolone
1Recognize the syndromeRecent jaundice with characteristic laboratory context raises alcohol-associated hepatitis.
2Exclude mimics and screen for infectionCultures, imaging, and targeted serologies prevent misdiagnosis and identify steroid hazards.
3Grade severityUse MELD to identify severe disease; Maddrey discriminant function is a historical companion, not the sole treatment gate.
4Treat and reassessProvide abstinence care and nutrition; if MELD is above 20 and the patient is steroid-eligible, reassess response with a Lille score on day 4 or 7.

Which treatment is most appropriate in addition to abstinence care and nutrition?
Reason it through
What makes the syndrome severe?Jaundice, coagulopathy, and MELD above 20 indicate high short-term risk.
What safety screen matters before steroids?Active infection, gastrointestinal bleeding, and other contraindications must be addressed.
What prevents prolonged futile exposure?A Lille score above 0.45 on day 4 or 7 identifies nonresponse.
Severe plus eligible can justify prednisolone; severe plus nonresponsive should prompt stopping it.

A 57-year-old woman with suspected severe alcohol-associated hepatitis has fever, hypotension, dysuria, bilirubin 16 mg/dL, INR 2.1, and a positive urine culture with bacteremia.
What is the most appropriate next step?
Reason it through
Why is fever not enough to settle the diagnosis?Inflammatory hepatitis can cause fever, so infection requires an active search.
What changes the immediate priority here?Culture-proven bacteremia with hypotension requires stabilization and antibiotics.
When can the liver-specific decision be revisited?After infection control and renewed assessment of risks, severity, and diagnostic certainty.
The steroid question comes after control of an active infection, not before it.
