Long-Term Follow-Up Of A Japanese Patient With Hepatitis B Virus Genotype H And Human Immunodeficiency Virus Coinfection

Hepatitis B virus (HBV) genotypes affect the pathogenesis of disease progression during the course of HBV infection. In Japan, HBV genotype H is one of the rare HBV genotypes. We recovered HBV genotype H from a blood sample from a Japanese HIV-infected patient with acute exacerbation of chronic HBV infection. Due to the development of drugs for treating HBV and HIV, HBV genotype H and HIV coinfection has been well controlled by nucleos(t)ide analogs and highly active antiretroviral therapy, respectively, from 2002 to 2019. Further study is needed with regard to HBV genotype H and its pathogenesis.
