19. Case 1: Diagnoses Fibrous septum formation with mixed features of: - chronic hepatitis C (mildly active) - fatty liver disease (? alcoholic vs. non-alcoholic)
20. Case 1: Diagnoses Fibrous septum formation with mixed features of: - chronic hepatitis C (mildly active) - fatty liver disease (? alcoholic vs. non-alcoholic) Comment: … The amount of steatosis in the specimen is significantly more than is usually seen with hepatitis C alone, implying possible concomitant fatty liver disease…
22. Case 1: Diagnoses Fibrous septum formation with mixed features of: - chronic hepatitis C (mildly active) - fatty liver disease (? alcoholic vs. non-alcoholic) Comment: … The amount of steatosis in the specimen is significantly more than is usually seen with hepatitis C alone, implying possible concomitant fatty liver disease; however, it must be kept in mind that hepatitis C itself may lead to insulin resistance in some patients and thus may also be a direct cause of non-alcoholic fatty liver disease in some patients.

45. HCV + HIV? On HAART: In large cohorts, possibly more aggressive, but individual biopsies look the same as HCV alone. Beware: drug toxicity
46. HCV + HIV? Untreated: Often more severe activity. Often more advanced disease.
47. HCV + HIV? Untreated: Often more severe activity. Often more advanced disease. Rare: fibrosing cholestatic hepatitis
48. HCV + HIV? Untreated: Often more severe activity. Often more advanced disease. Rare: fibrosing cholestatic hepatitis Beware: Infiltrating neoplasms, granulomas, HSV, CMV, biliary tract disease, etc.
