Prognosis
Acute Alcoholic Hepatitis
• Acute mortality (50% die within one month)– Hepatic encephalopathy– Coagulopathy (PT prolongation > 6 seconds over
control) – Bilirubin > 8mg/dl– Decreased albumin < 2.5 g/dl– Creatinine > 2mg/dl– Maddrey discriminant factor > 90 (4.6 x PT +
bilirubin)– Increase in serum TNF correlates with severity

TreatmentAlcoholic Hepatitis
• Abstinence• Nutritional support
– Protein, sodium, vitamins, Zn, Mg, Phos
• Propylthiouracil• Corticosteroids• Anabolic steroids (oxandrolone)• Colchicine• Pentoxifylline• Liver transplantation• Emerging therapies : anti TNF ab (?)

Corticosteroids in the treatment of
acute alcoholic steatohepatitis
• Anti-inflammatory • Use of corticosteroids in patients with
Maddrey score of >32 if– No evidence of gastrointestinal bleeding or
infection– Evidence of hepatic encephalopathy
• Look for early change in bilirubin levels (Lille criteria):
– Likely to respond if bilirubin on day 7 is lower than on 1st day of treatment (Mathurin et al 2003).
• Risks: – Infection – GI bleeding

Pentoxifylline
• Non-selective phosphodiesterase inhibitor
• Increases intracellular cAMP and cGMP
levels
• Inhibits TNFa production
• Used for treatment of claudication (400mg tid)
• Reduces fibroblast proliferation and collagen
secretion
• Excellent safety profile

Anti-TNF therapy - Clinical studies
• European study (Tilg et al 2003)– 12 patients moderate-severe AH – treated with Infliximab 5mg/kg single dose iv– 10 of 12 patients were alive at 15 month
• US study with TNF receptor antagonist (Menon et al 2004)
– Open label study with etanercept– Showed safety in patients with less severe AH
• Large double-blind randomized study (Tilg et al 2003)
– Prednisolone or Prednisolone+Infliximab (anti-TNFaantibody)
– Terminated due to increased infectious complications.

Conclusions:Endogenous danger signals released from hepatocytes induce a cellular cross-talk and activate
the inflammasome in immune cells.
Liver inflammation in alcoholic hepatitis is induced and

Focus on key elements of the pathogenesis of
alcoholic hepatitis
• Inflammatory cascade and innate immune activation– a demarcating feature of AH compared to mild to moderate alcoholic
liver disease
• Gut integrity – that is significantly altered in alcoholic hepatitis allowing pathogen-
associated molecular patterns (PAMPs) to enter the liver and systemic circulation and induce innate immune activation,
• Cell survival and death pathways – that contribute to liver dysfunction and the release of damage-
associated molecular patterns (DAMPs) that further fuel inflammation.
