Abstract:
Objective To determine the changes of peripheral levels of T helper cell cytokines of patients with chronic hepatitis B (CHB) during antiviral treatment,and to further explore its clinical significance.Methods The plasma levels of interleukin (IL)-2,IL-6,IL-10,interferon (IFN)-γ and tumor necrosis factor(TNF)-α of thirty-three CHB patients during antiviral treatment (entecavir) were measured using enzyme linked immunosorbont assay (ELISA).And their biochemical indicators of liver function were determined.The differences of cytokines levels before and after antiviral treatment were compared using ANOVA.The correlations between the changes of cytokines and alanine transaminase (ALT),hepatitis B virus (HBV) DNA levels were analyzed.Results Levels of IFNγ before and 12,24,48 weeks after treatment were (5.98±2.77),(5.95±3.37),(2.93±2.15) and (9.29±4.65) pg/mL,respectively (F=3.845,P＜0.05),which were positively correlated with ALT levels (r =0.396,P＜0.05).Both TNF-α and IL-10 levels declined after antiviral treatment,which were significantly different at different time points (F=20.156 and 16.695,respectively; both P＜0.05),and both levels of TNF-α and IL-10 were positively correlated with ALT levels (r=0.354and 0.316,respectively; both P＜0.05) and positively correlated with HBV DNA levels (r=0.382and 0.386,respectively; both P＜0.05).While both IL-2 and IL-6 levels were not significantly different between before and after antiviral treatment (F=0.010 and 0.932,respectively; both P＞0.05).The serum levels of ALT and HBV DNA before and after antiviral treatment were all significantly different (F=17.69 and 198.98,respectively; both P＜0.05),which declined gradually during treatment and were positively correlated (r =0.581,P＜0.05).Conclusions IL-10,IFNγand TNF-α may be involved in the pathologic process of CHB,and closely related to the deterioration of the disease.Monitoring plasma levels of these cytokines during antiviral treatment could be useful to understand the immune status and evaluate the efficacy of antiviral drugs.
