Correlation of serum TGF-β1 content with liver fibrosis and Th1/Th2 immune levels in patients with chronic hepatitis b

Objective:To investigate the correlation of serum TGF-β1 content with liver fibrosis and Th1/Th2 immune levels in patients with chronic hepatitis b.Methods: A total of 178 patients who were diagnosed with chronic hepatitis b in our hospital between February 2015 and August 2017 were selected as chronic hepatitis b group, and 100 healthy volunteers who received physical examination in our hospital during the same period were selected as normal control group. The differences in serum levels of TGF-β1, liver fibrosis indexes and Th1/Th2 cytokines were compared between the two groups, and the Pearson test was adopted to evaluate the correlation between serum TGF-β1 content and disease severity in patients with chronic hepatitis b.Results: Serum TGF-β1 level of chronic hepatitis b group was higher than that of normal control group;serum liver fibrosis indexes CⅣ, PC-Ⅲ, HA and LN levels were higher than those of normal control group;serum Th1 cytokines IFN-γ and IL-12 levels were lower than those of normal control group whereas Th2 cytokines IL-4 and IL-13 levels were higher than those of normal control group. Pearson test showed that the serum TGF-β1 level in patients with chronic hepatitis b was positively correlated with the degree of liver fibrosis and Th1/Th2 immune imbalance.Conclusions: Serum TGF-β1 expression is abnormally high in patients with chronic hepatitis b and directly correlated with the degree of liver fibrosis and immune imbalance.
