Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hepatitis B virus (HBV) infection constitutes a major public health threat worldwide. A total of 92 patients with HBeAg-negative chronic hepatitis B infection were recruited at Amiens University Hospital. The diagnostic workup included a physical examination.In conclusion, the study results confirmed that the HBV DNA level is associated with liver fibrosis status and that HBV viral load is strongly correlated with BCP and PC mutations, and it demonstrated that the impaired base pairing 1858-1896 mutations at the base of the bulge in the e encapsidation signal is independently associated with high serum HBV DNA levels.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The progression of liver disease in hepatitis B virus (HBV) infection is fostered by active virus replication. Mutations in the basal core promoter (BCP) and precore (PC) regions of the HBV genome are known to have an impact on viral replication. The aim of the present study was to assess the correlation of mutation profiles in the BCP and PC regions with the viral load in HBeAgnegative chronically infected patients. The HBV genotype, BCP/PC mutations, serum HBV DNA levels, and associated serological markers were analyzed in 92 HBeAgnegative chronically infected patients.
