Abstract:

Objective

To investigate the expression and clinical significance of serum interferon-stimulated gene 20kDa protein (ISG20) of patients with hepatitis B virus infection.

Methods

Total of 67 patients with chronic hepatitis B (CHB group), 58 patients with liver cirrhosis (LC group), 54 patients with liver cancer (HCC group) and 47 healthy controls were selected in Hanzhong Central Hospital from March 2017 to June 2018. Serum ISG20 protein levels were detected by enzyme-linked immunosorbent assay. The difference of serum ISG levels in different groups were compared. The serum ISG20 level and age, gender, count of red blood cell, count of white blood cell, platelet count and aspartate aminotransferase, alanine aminotransferase, total bilirubin (TBil), direct bilirubin (DBil), albumin, prothrombin, alpha-fetoprotein (AFP) and HBV DNA load of different groups were analyzed by Spearman’s correlation analysis.

Results

The serum ISG20 level in control group was 9.4 (0.82-25.72) ng/ml, which was significantly lower than that of the CHB group [18.6 (1.87-56.32) ng/ml; Z =-1.567, P = 0.034] and the HCC group [28.2 (3.09-81.42) ng/ml, Z =-1.854, P = 0.021]. The serum ISG-20 level in HCC group was significantly higher than that of CHB group (Z =-1.431, P = 0.041) and LC group [12.9 (2.81-77.54 ) ng/ml; Z =-1.987, P = 0.029). There was significant difference of serum ISG20 level between patients with different Child-Pugh grades in HCC group (H = 6.976, P = 0.031). Serum ISG20 levels of patients in HCC group were positively correlated with AST (r = 0.323, P < 0.001), ALT (r = 0.248, P = 0.036), TBil (r = 0.221, P = 0.031), DBil (r = 0.215, P = 0.043) and AFP (r = 0.176, P = 0.044); but negatively correlated with albumin (r =-0.239, P = 0.019).

Conclusions

Serum ISG20 levels were elevated in patients with HBV infection, especially in patients with HCC caused by HBV infection. Serum ISG20 levels had a certain correlation with progression and clinical parameters of HBV infection diseases.
