    Abstract:
    OBJECTIVE: To determine the relationship between hepatitis B virus (HBV) DNA levels and total histologic activity index (HAI), necroinflammation (HAI-NI), and fibrosis (HAI-F) scores. PATIENTS AND METHODS: Liver histology and HBV DNA levels were determined in 94 patients with chronic hepatitis B. RESULTS: There was no association between HBV DNA levels and liver histology in hepatitis-B-e antigen-positive patients (n = 43). In anti-HBe-positive patients (n = 51), HBV DNA levels correlated positively with HAI-NI (r = 0.31, p= 0.014) and HAI-F (r = 0.33, p= 0.017) scores. Though the majority of anti-HBe-positive patients with HBV DNA levels <10(5) copies/ml had mild necroinflammation and no fibrosis, 14.3% had established fibrosis. Anti-HBe-positive patients with core promoter mutations had a poorer histology compared to those without. There was no difference in the histology between anti-HBe-positive patients with and without precore mutations. Alanine aminotransferase (ALT) level correlated positively with HAI-NI score. Patients with persistently normal ALT levels had a significantly lower median HAI-NI score compared to patients with either persistently or intermittently elevated ALT levels. CONCLUSIONS: In anti-HBe-positive patients, though HBV DNA level <10(5) copies/ml was associated with better histology, 14.3% patients had established fibrosis. Further studies to define a better cut-off HBV DNA level to differentiate low- and high-risk patients for disease progression are required.
