Methods Thirty-six patients infected with genotype B hepatitis B virus (HBV) were recruited in this study. The serum levels of CXCL9, CXCL10, CCL3 and CCL5 were measured by ELISA before treatment. All the patients were treated with PegIFNα-2a 180 ?g every week and were followed up for six months. Results The results of binary logistic regression analysis found that the serum levels of CXCL9 and aspartate aminotransferase (AST) before treatment were the independent predictors for early virological response. The patients were then divided into two groups including a high CXCL9 group (serum level of CXCL939.51 ng/L) and a low CXCL9 group (serum level of CXCL939.51 ng/L). After the treatment for 3 months, the rates of early virological response were 78.95% (15/19) in the high CXCL9 group and 23.53% (4/17) in the low CXCL9 group, respectively (P0.05). After the treatment for 6 months, the rates of mai
