Host and Viral Factors Influencing Chronic Hepatitis B Infection Across Three Generations in a Family

Chronic hepatitis B (CHB) infection is influenced by both virological and host factors. A total of 5,920 CHB patients were classified into four groups based on HBV seromarkers: three-generation families (CHB grandmother, mother, and child), two-generation families (CHB mother/child pairs), individuals recovered from HBV infection, and a control group. Serological markers, viral load, liver function tests (LFT), HBV mutations, HLA-DQ variations, cytokine polymorphisms, and liver stiffness measurements (LSM) were analyzed using FibroScan. Point mutations in genes such as core/pre-core (G1896A/G1899A), polymerase (H248N, H267Q, N263D), S (G145R, S143L), and X (C1500T, T1464C) were observed in 30
