title: Liver iron stores and hepatitis B antigen status.
abstract: Higher serum iron and ferritin levels noted in hepatitis B antigen (HBAg) carriers than in noncarriers suggests that virus might actively replicate in hepatocytes, stimulate ferritin synthesis, and result in increased liver iron stores. A comparative semiquantitative study of immunohistochemical ferritin (0-12) and hemosiderin (0-9) was performed on 54 normal, 13 cirrhotic, and 70 nonneoplastic livers from patients with hepatocellular carcinoma, in each group, comparing amounts in HBAg-positive and HBAg-negative patients. Mean scores for ferritin and hemosiderin were high in all three groups, normal livers averaging 8.3 and 6, respectively, cirrhotic livers, 8.5 and 7.4, respectively, and carcinoma livers, 5.6 and 6.1, respectively. In each group, there was no significant difference in ferritin and hemosiderin mean scores in HBAg-positive and HBAg-negative patients. The large liver iron stores do not appear to be a consequence of hepatitis B virus infection alone. Their role in the development of hepatocellular carcinoma is still to be elucidated.
