Area of Science:

  • Hepatology
  • Virology
  • Molecular Biology

Context:

  • Hepatitis B virus (HBV) infection is a global health concern.
  • Accurate HBV genotyping is crucial for understanding disease progression and treatment response.
  • Previous studies have indicated geographical variations in HBV genotype prevalence.

Purpose:

  • To determine the predominant HBV genotype in Changchun.
  • To investigate the association between HBV genotypes and clinical severity, including hepatocellular carcinoma and liver cirrhosis.
  • To guide clinical management of hepatitis B.

Summary:

  • A study analyzed HBV S gene sequences from 216 patients using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP).
  • Genotype C was the most prevalent (81.02%), followed by genotypes D (9.72%) and B (8.8%).
