GPT and alcoholic hepatitis: For reference, patterns of liver injury in acetaminophen toxicity, ischemic hepatitis, alcoholic hepatitis, and hepatitis B virus can yield the following (respectively): aminotransferases >3500 IU/L with low bilirubin and high INR, aminotransferases 25-250 times the ULN and elevated serum lactate dehydrogenase, aspartate aminotransferase (AST) typically two to three times greater than ALT, and aminotransferases between 1000 and 2000 IU/L with ALT being greater than AST. In this case, the patient developed acute liver injury a day following initiation of levofloxacin therapy.
