dc.description.abstractLactoferrin (Lf) expression has been immunohistochemically investigated in 117 formalinfixed paraffin-embedded liver bioptic samples obtained from an equal number of patients affected by chronic hepatitis (HCV=76; HBV=17; HBV+HDV=14; cryptogenetic=10); in addition, 10 autoptic specimens of normal liver were studied as control. The Lf immunoreactivity was evaluated by an intensitydistribution (ID) score. The Lf immunoexpression was observed in 88 out of 117 (75%) cases of chronic hepatitis; interestingly, all liver specimens from HBV hepatitis showed a constant Lf reactivity with the highest ID-score, whereas the evidence of Lf was encountered in 54/76 (71.1%) HCV as well as in 11/14 (78.6%) HDV chronic hepatitis, thus documenting a variable degree of Lf immunostaining in relation to different viruses. Moreover, in 6/10 (60%) cases of cryptogenetic hepatitis Lf immunoexpression was documented, whereas all normal liver controls were unreactive. In HCV specimens, the Lf nuclear immunoreactivity appeared to increase with the progression of the disease, with a greater expression in genotype 1. In contrast, no relationship among Lf ID-scores and different stages or grades of HBV, HDV or cryptogenetic hepatitis was encountered. This fact may suggest a role for Lf as an unspecific defensive agent in chronic inflammatory liver diseases, similarly to that elsewhere reported in other inflammatory tissue injuries.es
