Predictors of histological indication for treatment in HBeAg negative chronic HBV infection

In this study, we evaluated the relationship of hepatitis B virus (HBV) DNA levels with liver histology and various other liver related parameters and the predictors of histologically active liver disease requiring treatment (Histological activity ≥6 and/or grade ≥2 by Ishak's classification) in patients with HBeAg negative chronic HBV infection. Demographic data, laboratory findings and liver histology findings of patients with no clinical cirrhosis who underwent liver biopsy considering HBeAg negative chronic hepatitis (HBV DNA >2000 IU/mL) were analyzed. Two hundred and fifteen patients were included in this retrospective study. Treatment indication by histologic findings were 85.7%, 61.2%, and 64%, respectively, in group 1 (HBV DNA ≥200 000), group 2 (HBV DNA 20 000-200 000), and group 3 (HBV DNA 2000-20 000 IU/mL) (P = 0.001). Group 1 was different from other groups in terms of aspartate aminotransferase (AST), alanine aminotransferase (ALT), fibrosis stage, necroinflammatory activity, and platelet count. Multiple logistic regression analysis revealed that, advanced age (cut-off was 46 years), higher than normal AST and HBV DNA ≥200 000 IU/mL (compared to group 3) were found to be the predictors of histologically active disease with treatment indication. Conclusively, most of the patients with HBV DNA ≥200 000 IU/mL showed treatment requiring liver injury, but also a significant portion of the patients with HBV DNA 2000-200 000 IU/mL carried an indication for treatment. Although age (>46 years) and AST (>40 IU/L) can be helpful to predict treatment requirement in patients with HBV DNA 2000-200 000 IU/mL, sufficient effort should be made to find out the significant liver damage.
