摘要
Alanine aminotransferase (ALT), hepatitis B virus (HBV) DNA levels and age are used commonly to assess liver histology in chronic hepatitis B. Increasing levels of HBV DNA are associated with the increasing prevalence of significant fibrosis in HBeAg-negative patients. It is unclear whether these data can be applied to HBeAg-positive patients. In present study, liver biopsies were performed and clinical parameters were measured in 234 treatment-naive chronic HBeAg-positive patients. The proportion of significant fibrosis in patients with ALT 1-2xULN was similar to in patients with ALT more than 2xULN (48.4% vs. 51.8%). Patients over 30 years of age (>30 years) had a higher prevalence of significant fibrosis than patients 30 years of age and younger (61.0% vs. 33.6%). Negative correlation between HBV DNA levels and significant fibrosis was observed in patients >30 years. The optimal level of serum HBV DNA to evaluate low risk of significant fibrosis was 6.7log10IU/ml. Patients with serum HBV DNA levels 8.5log10IU/ml all had no significant fibrosis, however, patients with HBV DNA levels <4.7log10IU/ml all had significant fibrosis. Logistic regressions showed that age, aspartate aminotransferase, platelet count, and HBV DNA levels were independent predictors of significant fibrosis. In summary, older age, elevated ALT, and lower HBV DNA levels are associated with significant fibrosis. Decreasing levels of HBV DNA are associated with increasing prevalence of significant fibrosis in patients >30 years. The threshold of HBV DNA levels for treatment of HBeAg-positive patients needs to be combined with age. J. Med. Virol. 86:1828-1837, 2014.
