Abstract

In this study, we investigated the correlation between the administration of various antiviral agents and the alternation of specific biomarkers induced by the hepatitis B virus (HBV). Eligible subjects diagnosed with chronic hepatitis B were prescribed with antiviral drugs at the Gastroenterology Internal Medicine Department of E University Hospital in Daejeon between May 2004 and September 2009. Lamivudine was prescribed to 66 out of 100 patients. Of the 12 patients, 6 (50.0%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative. Of the 39 patients, 23 (59.0%) showed higher than 40 IU/L alanine aminotransferase (ALT). Of the 65 patients, 41 (63.1%) showed HBV DNA decrease of 1 log, and were prescribed with Lamivudine. Adefovir was prescribed to 3 out of 100 patients. Of the 12 patients, 1 (8.3%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative, and was prescribed with Adefovir. Entecavir was prescribed to 19 (19.0%) out of 100 patients. Of the 12 patients, 3 (25.0%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative. Of the 12 patients, 3 (125.8%) showed higher than 40 IU/L ALT. Of the 65 patients, 14 (21.5%) showed HBV DNA decrease of 1 log, and were prescribed with Entecavir. Clavudine was prescribed to 7 out of 100 patients. Of the 12 patients, 1 (8.3%) showed a change from positive HBe antigen to negative HBe antigen. Of the 39 patients, 5 (12.8%) showed higher than 40 IU/L ALT. Of the 65 patients, 6 (9.2%) showed HBV decrease of 1 log, and were prescribed with Clavudine. These results do not show a statistically significant correlation between drugs and biomarkers. Data on combination therapy using Lamivudine and Adefovir show no statistically significant difference between drugs and biomarkers. Medications for periodic inspection was not correlated to HBe-antigen-negative conversion, ALT, and HBV DNA. HBV DNA was significantly reduced in patients with high levels of AST(aspartic acid aminotransferase) and ALT before treatment. In addition, the decrease of HBV DNA after 12 months of treatment was less frequently observed in patients treated with Lamivudine compared with other drugs. This result is associated with Lamivudine resistance. Although the association of drugs with diagnostic markers and the correct choice of treatment is difficult to determine, these results may be useful for further research on diagnosis and treatment of the hepatitis B virus.
