Abstract Spontaneous reactivation of the Hepatitis B virus (HBV) is rare in individuals with previously resolved infections. This report presents the case of a 71 year-old Japanese woman who experienced HBV reactivation without any prior immunosuppressive therapy or chemotherapy. Before the onset of liver injury, the patient was negative for hepatitis B surface antigen (HBsAg) but positive for hepatitis B surface antibody. She subsequently developed liver injury, with the reappearance of HBsAg and HBV DNA. The patient was successfully treated with tenofovir alafenamide, and prednisolone. Full-genome sequencing of HBV revealed subgenotype B1 without hepatitis B e-negative mutations in the precore and core promoter regions and 12 amino acid alterations in the pre-S1/S, P, and X genes. Notably, the S gene mutations D144A and K160N, which alter the antigenicity of HBsAg and potentially contribute to its reactivation, were identified. This case emphasizes the importance of vigilance for spontaneous reactivation of resolved HBV, highlighting the need for comprehensive genomic analysis to understand the associated virological intricacies.

Mutation Information
Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
