IX. Labs

  1. See Acute Hepatitis

X. Imaging

XI. Management

  1. Targeted therapy
    1. Delivery for pregnancy related Acute Liver Disease (especially Acute Fatty Liver of Pregnancy)
    2. Withdraw all known Hepatotoxins
    3. Treat known Hepatotoxin exposures
      1. Consult with poison control and hepatology
      2. Consider empiric N-Acetylcysteine in possible acute Toxic Hepatitis
        1. Effective beyond Acetaminophen Overdose or Amanita muscaria ingestion
        2. Duration typically longer (>24 hours) than for Acetaminophen Overdose (per poison control)
  2. Supportive care
    1. ABC Management
      1. Endotracheal Intubation often required
    2. Fluid and Electrolytes
      1. Volume expansion with crystalloid initially, but avoid Fluid Overload
        1. Consider Albumin 25% at 50-100 ml aliquot or Albumin 5% at 250 ml aliquot
        2. Liver failure is associated with hypoalbuminemia
      2. Correct acid-base status and Electrolyte abnormalities
      3. Monitor Serum Glucose
        1. Correct Hypoglycemia with IV D10 or D20 prn
      4. Hemorrhagic Shock
        1. Consider FFP or PCC4 for Coagulopathy and severe active bleeding
        2. INR is not an accurate measure of bleeding risk in the absence of Warfarin
      5. Vasopressors
        1. Consider Vasopressin as a first-line Vasopressor in liver failure
    3. Prevent GI Bleed
      1. H2 Blockers to maintain gastric pH >3.5
    4. Monitor for infection
      1. Complicated by Bacterial or fungal infection in 80% of cases
      2. Infection is often occult with non-specific changes in status (e.g. worsening encephalopathy)
      3. Routinely monitor urine, Chest XRay and other markers of infection
      4. Have low threshold to start Antibiotics and Antifungals
      5. Consider prophylactic Antibiotics (e.g. Ceftriaxone)
    5. Hepatic Encephalopathy
      1. Increased risk for cerebral edema, intracranial Hypertension and Uncal Herniation
      2. Monitor Hepatic Encephalopathy patients in ICU
      3. Hepatic Encephalopathy may be more severe in Acute Liver Failure than in longstanding Cirrhosis
      4. Obtain Head CT and Ocular Ultrasound for Optic Nerve Sheath Diameter
      5. General measures
        1. Consider Endotracheal Intubation
        2. Elevate head of bed to 30 degrees
        3. Control systemic Hypertension
        4. Lactulose (oral, rectal) lowers cerebral ammonia and may decrease ICH
      6. Other measures for lowering Intracranial Pressure (questionable efficacy unless temporizing for procedure)
        1. Lower Intracranial Pressure with Mannitol IV or Hypertonic Saline prn (while replacing urine losses)
  3. Transfer to center capable of performing Liver Transplant (if potential candidate)
    1. See Liver Transplant Center Referral Indications
    2. Other Liver Transplant referral indications
      1. Grade 3-4 Encephalopathy
      2. Adverse prognostic indicators as above

XII. Prognosis: Factors associated with poor outcomes

  1. Advanced age
  2. Halothane exposure
  3. Hepatitis C
  4. Coma (80% Mortality)
  5. Rapid decrease in liver span
  6. Respiratory Failure
  7. Marked ProTime prolongation
  8. Factor V Level <20%

Definition (MSHCZE) Rychlý nástup akutního SELHÁNÍ JATER, známého také jako fulminantní jaterní selhání, je forma onemocnění způsobená těžkým poškozením jater nebo masivní ztrátou HEPATOCYTŮ. Je to charakteristické při náhlém rozvoji jaterní dysfunkce a při ŽLOUTENCE. Akutní selhání jater se může vyvinout až v cerebrální dysfunkci či dokonce v jaterní kóma, což závisí na etiologii, která může zahrnovat jaterní ischémii, otravu léky, maligní infiltraci a virové hepatitidy jako např. potransfúzní hepatitidu typu B a C (HEPATITIDA B, HEPATITIDA C).

Definition (NCI) Rapid deterioration of liver function causing encephalopathy and coagulopathy. It results from damage to the liver parenchyma usually secondary to acetaminophen overdose or viral infections.
Definition (MSH) A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.
