title: Lymphocyte CD64 increased in patients with chronic HBV infection.
abstract: CD64 was up-regulated in infection diseases, but there was no report about the change of CD64 in chronic hepatitis B virus (HBV) infection. The purpose of this study was to determine whether there was a dynamic change of CD 64 index and to judge the value to antiviral treatment. 96 CHB patients were enrolled and selected 33 healthy adults as control. We detected the level of CD64, found the level of CD64 were significantly increased in chronic HBV infection patients, especially the lymphocyte CD64 (8.12 ± 0.23 vs. 6.25 ± 0.27; P < 0.001). Further, we proved CD64 index was increased in various stages of chronic HBV infection. ROC curve analysis showed the level of lymphocyte CD64 had higher AUC value than neutrophil or monocyte. Then we monitor longitudinally the impact of the treatment with interferon-α and found that the suppression of viral replication induced by interferon-α resulted in a decrease in CD64 index. In conclusion, this study showed that CD64 index was increased in chronic HBV infection patients and changed with the course of disease, the therapy of interferon-α would correct it, and analysis prompted that the level of lymphocyte CD64 would be more suitable for as a biomarker to judge the condition of chronic HBV infection and the curative effect of interferon-α treatment.
