Abstract

We treated a 51-year-old Japanese man with chronic hepatitis B (viral load 7.6 LC/mL, genotype C). HBV DNA and HBe antigen were undetectable during the administration of the nucleic acid analogs (NUCs) lamivudine and adefovir, although the concentration of HBs antigen (HBsAg) was 851.2 IU/mL. The HBsAg levels were reduced 150-fold when Peg-IFNα-2a was administered weekly for 48 weeks and did not increase during the rest period. Therefore, Peg-IFNα-2a was administered twice each week. During this time, HBsAg reached undetectable concentrations, and HBs antibody was detected and continued to be detectable during the three-year follow-up. These unprecedented findings suggest that IFN may contribute to the seroclearance of HBsAg in patients treated with NUCs.

Keywords: HBs antibody; HBs antigen; case reports; chronic hepatitis B; interferon.

抽象

我们治疗了一名51岁的日本男子,患有慢性乙型肝炎(病毒载量7.6 LC / mL,基因型C)。 HBs DNA和HBe抗原在核酸类似物(NUCs)拉米夫定和阿德福韦给药期间无法检测到,尽管HBs抗原(HBsAg)浓度为851.2 IU / mL。每周施用Peg-IFNα-2a48周后,HBsAg水平降低了150倍,而在休息期间则没有升高。因此,每周两次施用Peg-IFNα-2a。在这段时间内,HBsAg达到了无法检测的浓度,并且在三年的随访期间检测到了HBs抗体并继续检测到。这些空前的发现表明,在NUCs治疗的患者中,IFN可能有助于HBsAg的血清清除。
