Cytokines predict virological response in chronic hepatitis B patients receiving peginterferon alfa-2a therapy

Figure 2 Receiver operating characteristic curves of hepatitis B virus deoxyribonucleic acid, hepatitis B e antigen, and cytokines for predicting virological responses. A: The receiver operating characteristic curves values of the serum hepatitis B virus deoxyribonucleic acid and hepatitis B e antigen levels measured before peginterferon therapy were 0.879 and 0.964, respectively. The sensitivity and specificity of the baseline thymus and activation-regulated chemokine were 72.70% and 73.30%, respectively; B: The sensitivity and specificity of the baseline macrophge inhibitory protein-1 delta, CXC-chemokine ligand 9, CXC-chemokine ligand 6, and interferon gamma-induced protein 10 levels in predicting virological responder were 69.20% and 84.60%, 76.90% and 76.90%, 61.50% and 84.60%, and 61.50% and 92.30%, respectively. HBeAg: Hepatitis B e antigen; HBV: Hepatitis B virus; TARC: Thymus and activation-regulated chemokine; CXCL6: CXC-chemokine ligand 6; MIP-1d: Macrophge inhibitory protein-1 delta; IP10: Interferon gamma-induced protein 10.
