Comparison of clinicopathological features for indications of different types of antiviral therapy in chronic hepatitis B

Abstract

Objective: To compare and analyze the clinicopathological features and significance for indications of different types of antiviral therapy in chronic hepatitis B (CHB). Methods: Clinical data of 861 CHB cases who received liver biopsy, had hepatitis B virus (HBV) DNA-positive (> 30 IU/ml) and met the indications for antiviral therapy from January 2014 to December 2019 were included. Liver pathological changes and their correlation with clinical characteristics were compared and analyzed. According to different data, t-test, analysis of variance, nonparametric test, χ2 test, Ridit and logistic regression analysis were used for statistical analysis. Results: Most of the cases (72.24%) had remarkable pathological damage. The degree of liver fibrosis was higher in the normal than the abnormal group (P<0.001). 17.54% cases had hepatic steatosis. The vast majority of cases (97.33%) had positive hepatitis B surface antigen (HBsAg), while only 50.87% had positive hepatitis B core antigen (HBcAg). The positive correlation factors affecting the severity of liver histopathology were alkaline phosphatase level, while the negative correlation factors were positive HBcAg staining, albumin and platelet level. The degree of liver inflammation and fibrosis had statistically significant differences with different HBcAg staining levels (χ2=44.142 and 102.386, respectively; P<0.001), and the severity was more apparent in the negative group. Conclusion: There exist differences in clinicopathological features for indications of different types of antiviral therapy in patients with CHB. Liver function test range is inconsistent with degrees of hepatic histological severity. The positive and intensity of liver tissue HBcAg staining, and albumin and alanine aminotransferase levels have negative correlation with disease severity.
