Abstract Objective: The aim of this study was to evaluate the one-month immune response to two different doses (10 and 20 μg) of recombinant hepatitis B vaccine in adults aged 25-46 years. Methods: Subjects who were negative for hepatitis B surface antigen (HBsAg), hepatitis B antibody (anti-HBs)

To improve a previously constructed broadly neutralizing hepatitis B virus (HBV)-specific preS1 humanized antibody (HzKR127), we further humanized it through specificity-determining residue (SDR) grafting. Moreover, we improved affinity by mutating two residues in heavy-chain complementarity-determi

Two commercial quantitative immunoassay platforms are currently available for the detection of hepatitis B surface antigen (HBsAg) within a wide range of concentrations: the Architect HBsAg assay and the Elecsys HBsAg II. However, there are limited data concerning their performance in patients who a

Nucleoside analog(NA)投与を行ったB 型慢性肝炎18 例(男性13 例、女性5 例、観察期間中央値55 ヵ月)を対象にした。治療前後の比較が可能であった8 例では、治療前のHBsAg 量とHBV-DNA 量およびHBcrAg 量には相関傾向がみとめられた。治療開始時に高値を示したHBV-DNA 量は、全例検出感度以下に著減した。しかし、HBsAg 量が減少したのは3 例のみで、 …
