Abstract

<p>Hepatitis B surface antigen (HBsAg) levels in sixteen patients who underwent switching of previous nucleos(t)ide analogues (NAs) to Tenofovir (TDF) were evaluated. Patients were classified into Adefovir (ADF)-pretreated group and Entecavir (ETV)-pretreated group. HBsAg levels were significantly decreased throughout the course, especially after administration of TDF in all patients. In ADF-pretreated group, no significant difference of HBsAg levels was observed before and after administration of TDF. On the other hand, HBsAg levels after administration of TDF were significant decreased, while no significant difference was observed before administration of TDF in ETV-pretreated group. As conclusion, it is suspected that administration of TDF may have some effect on control of HBsAg levels.</p>
