Correlation Between Histologic Staging, Hepatitis C Virus Genotypes and Clinical Features in HCV Chronic Hepatitis: Evidence of A New Pattern

Genome heterogeneity may be related to the wide variability of clinical and pathological features in hepatitis C virus (HCV)-related chronic liver disease. This paper addresses the possible association between HCV subtypes and clinical and histological features of chronically infected patients. Sixty-eight consecutive liver biopsies of chronic hepatitis constituted the basis of the study. HCV genotyping was performed on frozen tissue. Grading of necroinflammatory activity and staging of fibrosis were histologically assessed. Serologic HCV-RNA and liver function were assessed at the same time. All information was compared with clinical data including age, sex, HCV serology, and probable data and route of infection. Two cases were excluded as inadequate tissue was available. Five cases were negative to HCV-RNA in both serum and tissue. In 61 cases HCV RNA was present at the same time in serum and liver tissue. Forty-four patients were men (72%) and 17 (28%) were women. Two peaks of age were observed: 1 in t...
