Review article: hepatitis B core-related antigen (HBcrAg): an emerging marker for chronic hepatitis B virus infection

Lung-Yi Mak; Danny Ka-Ho Wong; Ks Cheung; Wkw Seto; Ching-Lung Lai; M.-F. Yuen

Chronic hepatitis B (CHB) cannot be completely eradicated due to the presence of covalently closed circular DNA (cccDNA) in the nuclei of infected hepatocytes. While quantification of intrahepatic cccDNA requires liver biopsies, serological markers can be non‐invasive alternatives to reflect intrahepatic viral replicative activity. Recently, hepatitis B core‐related antigen (HBcrAg) has been advocated as a novel serum marker for disease monitoring and prognostication of CHB.

We studied the intrahepatic hepatitis B virus (HBV) replicative status in 40 people with occult hepatitis B infection (OBI) and 40 patients with chronic hepatitis B (CHB). Intrahepatic HBV DNA, covalently closed circular DNA (cccDNA), and pre-genomic RNA (pgRNA) were quantified. Patients with OBI had median necroinflammation and fibrosis scores of 1 and 0, respectively. Intrahepatic total HBV DNA, cccDNA and pgRNA were detectable in 30 (77%), one (3%) and five (13%) of the participants with OBI, respectively. People with OBI had lower median intrahepatic total HBV DNA than the patients with CHB (p < 0.0001). They had nearly normal liver histology and low intrahepatic HBV replication.
