Abstract
BACKGROUND AND AIM: The data on the prevalence and predictors of significant fibrosis (≥F2, METAVIR) in chronic hepatitis B virus (HBV) patients with low viremia are limited. We aimed to assess both the prevalence predictors of ≥F2 fibrosis in hepatitis B envelope antigen-negative patients with HBV DNA <20,000 IU/mL. METHODS: Hepatitis B envelope antigen-negative patients (n=213) with mean HBV DNA <2000 IU/mL (n=97) and HBV DNA 2000 to 20,000 IU/mL (n=116) were included and all had liver biopsy. Variables significantly associated with ≥F2 fibrosis on an univariate analysis were included in a multivariate logistic regression model. RESULTS: Overall, 40 (18.8%) patients had ≥F2 fibrosis, with no difference between those with mean HBV DNA <2000 IU/mL (19.6%) compared with patients with HBV DNA of 2000 to 20,000 IU/mL (18.1%; P=0.782). Fibrosis ≥F2 was similar in patients with HBV DNA <2000 versus 2000 to 20,000 IU/mL in relation to varying alanine aminotransferase thresholds (P>0.05), and was less frequent in persistently normal alanine aminotransferase patients (13.6%) when compared with those with elevated or fluctuating levels (25.3%, P=0.030). Fewer patients under 40 years of age had ≥F2 fibrosis (12.5%) as compared with older ones (28.2%; P=0.004). Logistic regression analysis identified higher aspartate aminotransferase [odds ratio (OR), 6.21; 95% confidence interval (CI), 2.48-15.54; P<0.0001], lower albumin (OR, 0.86; 95% CI, 0.78-0.95; P=0.002), platelet count (OR, 0.99; 95% CI, 0.98-0.99; P=0.013), and age (OR, 1.05; 95% CI, 1.01-1.09; P=0.024) as independent predictors of significant fibrosis. CONCLUSIONS: A small but significant minority of HBV patients with low viremia harbor significant fibrosis, although its rate is not different in those with viremia above or below 2000 IU/mL. Our findings may guide in decisions regarding liver biopsy and treatment in this category of patients.
