ABSTRACT
Objective To investigate whether there are correlation among changes of Treg/Th17 ratio with virological response and serological re?sponse in patients with hepatitis B e antigen(HBeAg)?positive chronic hepatitis B(CHB)after receiving entecavir. Methods 27 patients with HBeAg?positive CHB were enrolled for the study. Peripheral blood Treg cell frequency and Th17 cell frequency,HBV DNA,alanine aminotransfer?ase levels,hepatitis B virus marker were detected before and after entecavir treatment at 4,12,24,36,and 48 weeks. Peripheral blood Treg cell frequency and Th17 cell frequency of 20 healthy volunteers were detected as well. Results Treg/Th17 ratio of patients decreased from 4 week and reached the lowest point at 12 weeks. Treg/Th17 ratio(12 weeks)of the patients who got the early virological response and HBeAg disappeared was lower than others,and the difference was statistical significant. Conclusion Treg/Th17 ratio changes in HBeAg?positive CHB patients receiv?ing entecavir antiviral treatment. Treg/Th17 ratio(12 weeks)showed significant correlation with early virological response and HBeAg disappear?ance. The changes of Treg/Th17 ratio may provide a reference of curative effect.
