Background:Hepatic histological responses described in hepatitis C virus (HCV) infection include bile duct damage, lymphoid follicles and/or aggregates in portal tracts, large- and small-droplet fat, Mallory body-like material in hepatocytes, liver cell dysplasia and multinucleation, and activation of sinusoidal inflammatory cells. The specificity of these lesions for HCV infection is uncertain. Methods:In two multicenter trials of recombinant interferon alfa therapy for chronic hepatitis C and B, the frequency of these eight lesions in pretherapy and posttherapy liver biopsy specimens was examined to determine the set of features, if any, that distinguishes HCV from hepatitis B virus (HBV) infection. The lesions were scored in 317 HCV biopsy specimens and 299 HBV specimens. Results:Stepwise logistic regression determined a set of three features more likely to be seen in HCV than in HBV infection: bile duct damage [odds ratio (OR), 4.7; 95% confidence interval (CI), 1.8–12.3], lymphoid follicles and/or aggregates (OR, 2.4; 95% CI, 1.2–4.7), and large-droplet fat (OR, 2.4; 95% CI, 1.4–4.1). A fourth lesion, Mallory body-like material, was seen only in HCV biopsy specimens (OR, 71.6; 95% CI, 4.4–996.1). Conclusions:These four histological lesions are useful pathological parameters in the diagnosis of liver disease caused by HCV. |
