Abstract: Liver biopsies in hepatitis C frequently show bile duct damage, lymphoid follicles, large and small droplet fat, hepatocyte multinucleation. Mallory bodylike material, and activation of sinusoidal inflammatory cells. Even though these lesions are useful parameters in the diagnosis of hepatitis C, their specificity remains uncertain. Endotheliitis-like changes of small portal veins have been described for various liver diseases, including viral hepatitis. The aim of the present study was to investigate the prevalence and severity of endotheliitis-like changes in chronic hepatitis C in comparison with chronic hepatitis B. For this purpose, liver biopsies of 50 patients with chronic hepatitis C and 48 patients which chronic hepatitis B were systematically analyzed for the presence of endotheliitis-like changes. Endotheliitis-like changes were defined as lymphocytic infiltration of venous walls, subendothelial lymphocyte accumulation, adherence of lymphocytes to the endothelium, and endothelial cell damage. Endotheliitis-like change severity was graded (borderline/questionable; slight to moderate; severe), and endotheliitis-like changes were analyzed in small portal veins and in central veins. Endotheliitis-like changes were significantly more frequent in chronic hepatitis C than in chronic hepatitis B (41.5% vs. 6.9%; ~ 0 . 0 5 ) . In chronic hepatitis C, endotheliitis-like changes predominated in small portal veins, but 27% of small hepatic veins were involved as well. The findings indicate that endotheliitis-like changes may represent a useful histological parameter in the diagnosis of chronic hepatitis C.
