The role of liver biopsy in chronic Hepatitis B treatment guidelines remains incompletely defined. Our aim was to correlate histologic disease severity with demographic, biochemical and virologic parameters as currently used in Hepatitis B treatment guidelines. We conducted an Institutional Review Board (IRB) approved retrospective cross-sectional study of chronic Hepatitis B patients between January 2001 and July 2009. Patients with at least two Alanine Aminotransferase (ALT) values (6 months apart), with detectable Hepatitis B DNA quantitative levels at the time of initial evaluation, unchanged HBeAg status over a minimum of 6 months but no prior history of antiviral therapy, alcohol abuse, co-infection, hepatocellular carcinoma, iron overload or liver decompensation were reviewed. Advanced histological disease was defined as a METAVIR score of greater than or equal to stage and/or grade 3 (≥S/G 3). Multivariable binary logistic regression was used to determine the independent predictors of advanced histology. One hundred and twenty-eight patients met inclusion criteria. On multivariate logistic regression analysis, viral load was not an independent predictor. However, age ≥40, abnormal ALT and HBeAg(+) were independent predictors of ≥S/G3. Controlling for ALT and HBeAg status, patients ≥40 years old had 14.5 times the adjusted odds of ≥S/G3 (95% CI, 4.24–49.54) while 31% of HBeAg(-) /Low Viral load patients had ≥S/G3. Current HBV-treatment guidelines do not fully predict advanced histological disease. In the group where all the current guidelines recommend observation without treatment, one third had advanced histology on liver biopsy. |
