[Liver hemosiderosis study in chronic viral hepatitis].
In chronic viral hepatitis the histopathological exam can reveal the presence of liver iron deposits in 10 to 73% of patients. Iron deposits are usually found in Kupffer cells, in endothelial cells and portal macrophages, and extremely rarely in hepatocytes.


OBJECTIVE
To evaluate the incidence of hepatic hemosiderosis in chronic viral hepatitis.


METHODS
549 morphopathological features of liver biopsy specimens performed in the Gastroenterology and Hepatology Institute IaSi, between January 1 2003 and December 31 2007 have been analyzed. Semiquantitative assessment of the degree of hepatic iron overload was performed and the localization of haemosiderin deposits: at the level of hepatocytes, the reticuloendothelial system or mixedly. The same anatomopathologist examined the blades and interpreted the results.


RESULTS
The medium age of patients who underwent liver biopsy was 45.08 years +/- 10.045. Positive iron staining was found in 22.8% of cases, more frequently in males (31%), and in 91.82% of cases iron deposits were grade 1-2. The association of alcoholic etiology did not influence the incidence of hemosiderosis: 23% in patients with hepatitis and no ethanol exposure vs 25% in cases of strictly viral etiology. Deposits of haemosiderin were more frequent in viral hepatitis B (38.6%) than in viral hepatitis C (26.9%). In 34% of cases stainable iron was found only in reticuloendothelial system and in 46% of cases both in Kupffer cells and hepatocytes.


CONCLUSIONS
Almost a quarter of chronic viral hepatitis cases are associated with liver deposits of haemosiderin, with features of secondary iron overload (deposits localized in the mesenchymal areas or mixedly). There is a higher risk of hemosiderosis in men, especially for those between 30 and 50. Liver iron overload levels in chronic viral hepatitis are, in most cases, low or medium, and the association with an alcoholic etiology does not influence the incidence of hemosiderosis in chronic viral hepatitis.
