Patient Case: 43-year-old male • Previous intravenous drug user • Alcohol intake > 50 g/day • HCV RNA 6 log10 copies/ml • Genotype 1 • HBV and HIV negative • Weight 90 Kg; height 170 cm
Patient Case: past history • In 1997: liver biopsy indicates chronic “active” hepatitis (i.e. METAVIR A2F2) • Treatment with IFN 3M IU thrice a week • Treatment stopped after 3 months because of poor tolerance and depression • Normalisation of ALT but no information on HCV RNA • Lost to follow-up until 2002
2002: Laboratory & morphologic results HB (g/dl) WBC (/mm3) Platelet count (/mm3) AST (IU/L) ALT (IU/L) GGT (IU/L) AP (IU/L) Total bilirubin (µmol/L) PT 14 6000 100 000 120 70 500 150 15 80% Liver US: steatosis, heterogenous parenchyma
Patient Case: liver biopsy • Metavir F3 with steatosis and NASH
