Introduction
Includes diseases of the liver.
Laboratory
- prolonged protrombin time
- prolonged aPTT
- serum albumin low
- plasma fibrinogen is low & possibly dysfunctional
- complete blood count (CBC)
- iron studies
- serum ferritin (rule out hemochromatosis)
- urinalysis
- tyrosine crystals in urine, may occur with leucine crystals in urine
- see ARUP consult[2]
* also see cirrhosis
Differential diagnosis
- hepatocellular disease
- hepatocellular injury results in elevated serum AST & serum ALT
- viral hepatitis or drug hepatitis results in serum AST & serum ALT > 1000 U/L (with serum ALT > serum AST) & serum bilirubin (total) > 15 mg/dL
- serum ALT > 5000 U/L suggest acetaminophen toxicity or hepatic ischemia
- serum AST/ALT > 2.0 suggests alcoholic hepatitis
- prolonged PT/INR & low serum albumin suggest hepatocellular dysfunction
- minimal serum AST & serum ALT in patients with obesity & hyperlipidemia suggest non-alcoholic fatty liver disease (NAFLD)[1]
- hepatocellular injury results in elevated serum AST & serum ALT
- hepatobiliary disease
- increased serum bilirubin
- increased serum alkaline phosphatase
- lesser (than hepatocellar) elevations in serum AST & serum ALT[1]
Management
- coagulopathy of liver disease
- vitamin K
- cryoprecipitate to maintain plasma fibrinogen > 10 mg/dL
- platelet transfusions to achieve latelet count > 75,000/uL[1]
- utility of fresh frozen plasma limited by short 1/2life of coagulation factors & risk of volume overload[1]
- prothrombin concentrates not recommended because of cost & prothrombotic complications[1]
