Abstract

Objectives: To describe some characteristics of HBcrAg in chronic hepatitis B patients treated with
Nucleot(s)ide Analogues (NAs) with HBV DNA quantitative test results below the detection threshold or undetectable and to determine the correlation coefficient between HBcrAg and other biomarkers. Our study was conducted from November 2022 to August 2023 at the Outpatient Department of Giai Phong campus, National Hospital for Tropical Diseases.
Methods: Cross - sectional descriptive study.
Results and conclusions: 225 patients with chronic hepatitis B with nucleos(t)ide analogues intake for
2 - 4 years were eligible. The median HBcrAg concentration was 4.2 logU/ml. The rate of HBcrAg ≥ 3 was 76.4% that accounted for 3/4 of the study population. HBcrAg concentration had a statistically significant
difference according to HBsAg concentration (p < 0.001) and HBeAg (p < 0.001). HBcrAg concentration
had positive correlated with HBsAg concentration (r = 0.337, p < 0.001) regardless of HBeAg status.
However, HBcrAg concentration was only positively correlated with HBsAg concentration in the HBcrAg
≥ 3 log U/ml group (r = 0.32, p < 0.001) and the HBsAg > 1000 IU/ml group (r = 0.272, p = 0.006). In the group of decreased platelet count , HBcrAg concentration correlated with platelet count in a moderate negative (r = -0.597, p = 0.031).
