Impact of Liver Biopsy on the Decision to Treat Patients with Chronic Hepatitis B Genotype D Virus Infection

Objectives: Patients with chronic hepatitis B virus (HBV) may exhibit significant liver pathology despite alanine aminotransferase (ALT) and HBV DNA levels below the cutoff values advised by treatment guidelines. We evaluated candidacy for HBV therapy when baseline histopathological changes are taken into consideration. Methods: Clinical, biochemical, serological, virological, and histopathological (METAVIR score) data of 117 patients with HBeAg-negative chronic HBV genotype D were collected and analyzed. Results: Significant pathology (>= F2 and/or >= A2) and fibrosis (>= F2 +/- >= A2) were found in 73 (62.4%) and 59 (50.4%) patients, respectively. Based on HBV DNA (>2,000 IU/ml) and ALT levels >2 x 40 U/I (the standard cutoff value), only 31 (26.5%) patients were candidates for therapy. This increased to 58 (49.6%) patients when the new ALT cutoff values (30 U/I for males, and 19 U/I for females) were applied. Relying on either >= F2 and/or A >= 2 or >= F2 +/- >= A2 increases the treatment candidacy to 73 (62.4%) and 59 (50.4%) patients, respectively. Also, when compared with standard ALT cutoff values, applying both new ALT cutoff values with either significant pathology or fibrosis increases treatment candidacy to 28 (23.9%) and 42 (35.9%) patients, respectively. Conclusion: Liver pathology is more reliable than ALT and HBV DNA in the decision to treat patients with HBeAg-negative chronic HBV genotype D. (C) 2014 S. Karger AG, Basel
