Demographics, hepatitis B virus deoxyribonucleic acid quantity, hepatitis B e-antigen, aspartate aminotransferase, alanine transaminase, international normalized ratio, total/direct bilirubin, albumin and thrombocyte counts as well as histological activity index and fibrosis scores were noted. Data was analysed using SPSS 22.Results: Of the 140 subjects, 70(50%) each were cases and controls. The overall mean age of the sample was 43.38±15.07 years (range: 18-70 years). There was positive correlation of histone H3.3 with hepatitis B virus deoxyribonucleic acid, aspartate aminotransferase, alanine transaminase and international normalized ratio levels. Histone H4 levels only correlated with hepatitis B virus deoxyribonucleic acid and international normalized ratio. Hepatitis B e-antigen positivity was present in 14(20%) of the cases.Conclusion: Histone H3.3 levels appeared to be associated with pathophysiological changes in chronic hepatitis B patients, suggesting that future treatments should target H3.3.Keywords: Histone H3.3, Histone H4, Extracellular histone, Chronic Hepatitis B, HBV.(JPMA 70: 1596; 2020)DOI:https://doi.org/10.5455/JPMA.19365eninfo:eu-repo/semantics/openAccessHistone H3.3Histone H4Extracellular histoneChronic Hepatitis BHBVArticle10.5455/jpma.1936533040116
