- The incidence of severe hepatitis A virus (HAV) infection has been increasing. However, clinicopathologic features of severe HAV infection that lead to liver transplantation (LT) have not been reported in Korea. We retrieved 16 LT cases with HAV infection during the last 3 years at Asan Medical Center, Seoul, Korea. Fifteen cases progressed to hepatic encephalopathy. Thirteen cases survived with or without complications, and three patients died of sepsis. The explanted liver showed massive or zonal necrosis with moderate to severe cholestasis. The zonal distribution of necrosis was frequently associated with endothelialitis of portal and/or central veins. Degenerative changes of hepatocytes were various in degree and distribution. Viral inclusions were suspected in two cases. Although HAV infection is usually confirmed by serological tests, significant venulitis of central and/or portal veins and viral inclusions, which are rarely observed, can suggest an HAV infection as a cause of massive hepatic necrosis of unknown mechanism.

- BACKGROUND
Differentiation of viral hepatitis from acute cellular rejection (ACR) after liver transplantation can be difficult because of overlapping histological features. Here we investigated clinicopathologic characteristics of 311 liver allograft biopsies and searched for characteristic histopathological features that would facilitate the differential diagnosis between hepatitis B virus (HBV) infection and ACR. METHODS: A retrospective clinicopathologic examination of 311 liver allograft biopsies consisting of clinically proven ACR or HBV infection was performed. Immunohistochemical staining for HBcAg and HBsAg was done for 64 allograft biopsies showing HBV infection. RESULTS: Moderate to severe bile duct damage, diffuse centrilobular necrosis and centrilobular inflammation (p<0.000, for each) were more frequently observed in cases of ACR, whereas diffuse acidophilic bodies and spotty necrosis (p<0.000, for each) were more prevalent in cases of HBV infection. Immunopositivity for HBcAg (n=60, 93.8%) was higher than that for HBsAg (n=14, 21.9%) CONCLUSIONS: The presence of moderate to severe bile duct damage, diffuse centrilobular necrosis and centrilobular inflammation was a characteristic feature of ACR, whereas diffuse distribution of acidophilic bodies or spotty necrosis was the only characteristic feature of HBV infection. HBcAg was a more sensitive immunohistochemical marker than HBsAg for detecting HBV infection in liver allograft biopsies.
