Abstract:
Objective:To analyze the liver pathology, clinical characteristics and influence factors in patients with chronic hepatitis B virus (HBV) infection in immune tolerant phase (IT).Methods:The clinical data of 273 patients in IT phase who underwent liver biopsy from January 2015 to December 2019 were included in this study. The correlation between liver pathological changes and clinical features was analyzed.Results:There were 43 cases (15.75%) with liver histologic activity ≥ G2, 30 cases (10.99%) with liver fibrosis ≥ S2, and 55 cases (20.15%) with liver pathology ≥ G2 and/or ≥ S2. A total of 17.95% patients had liver steatosis. The majority (98.17%) of tissue samples were positive for HBsAg staining, while only 79.49% were positive for HBcAg. The characteristics of liver pathology were comparable in men from women patients. The differences of G and S were not statistically significant according to different HBsAg positivity, while those were statistically significant according to different HBcAg positivity. By univariate and multivariate analysis, the independent risk factors of pathological severity were HBcAg intensity, HBeAg level, and age. However, the differences of liver histologic activity and fibrosis were not statistically significant between those younger than 30 years old group from those older than 30 years old, neither between those younger or older than 40. Although the diagnostic value of liver inflammation and fibrosis 5 (LIF-5) was better than that of aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis 4 score (FIB-4), three diagnostic models for predicting the pathological severity were not strong enough (all area under the curves<0.8). Only the specificity of LIF-5 for predicting≥ G2, ≥ G2 and/or ≥ S2 was over 80%.Conclusions:Approximately 20% patients with chronic HBV infection in IT phase have progressive liver inflammation or fibrosis. The intensity of liver HBcAg and HBeAg level are negatively correlated with the severity of disease. The diagnostic models or most clinical indicators have low predictive effect for chronic HBV infections in IT phase.
