Abstract PURPOSE: The purpose of this study was to present a fatal case of fulminant hepatitis B (FHB) that developed in a renal transplant recipient, immunized against hepatitis B, 1 year post transplantation. METHODS: Polymerase chain reaction amplification and full genome sequencing were performed to investigate whether specific mutations were associated with hepatitis B virus (HBV) transmission and FHB. RESULTS: Molecular analysis revealed multiple mutations in various open reading frames of HBV, the most important being the G145R escape mutation and a frameshift mutation-insertion (1838insA) within the pre-C/C reading frame. CONCLUSIONS: Our results highlight the possibility of developing FHB, despite previous immunization against HBV or administration of hyperimmune gammaglobulin, because of the selection of escape virus mutants. The current literature and guidelines regarding renal transplantation from hepatitis B surface antigen (HBsAg)-positive to HBsAg-negative patients were also reviewed.

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.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
