Histological Findings in Antigen E Positive and Negative in Chronic Hepatitis B.

Abstract

Objective: To determine the histopathological findings in patients with HBeAg-positive chronic HBV infection (immunotolerant phase in old terminology) and HBeAg-negative chronic HBV infection (inactive carrier phase in old terminology).

Study design: Observational study. Place and Duration of the Study: Department of Gastroenterology, University of Health Sciences, Diyarbakir Gazi Yasargil Education and Research Hospital, Diyarbakir, Turkiye and Diyarbakir and Mersin University School of Medicine, Diyarbakir, Turkiye, from May 2014 to August 2022.

Methodology: The difference between fibrosis and histological activity indices of 289 patients in the immunotolerant and inactive carrier phase who had liver biopsy was examined statistically. Additionally, the relationship of these data with age and gender was investigated.

Results: While 236 (81.7%) of the patients were in the inactive carrier phase, 53 (18.3%) patients were in the immunotolerant phase. The mean fibrosis score of patients in the immunotolerant stage was 2.0 ± 1.2, while it was 2.0 ± 1.0 in inactive carriers (p = 0.753). The number of patients with a fibrosis score of two and above was 21 (39.6%) in immunotolerant patients and 52 (22.0%) in inactive carrier patients (p = 0.004). In patients under 30 years of age, the mean fibrosis score was 1.7 ± 1.0. It was 2.0 ± 1.1 in those over 30 years of age (p = 0.016).

Conclusion: Biochemical parameters or viral load cannot clearly reflect cellular damage in the liver. In the future, HBV DNA positivity alone may be the only criterion for the treatment.

Key words: Chronic viral hepatitis B, Fibrosis, Immune tolerance phase, Inactive carrier phase.
