Quantitative PCR-based high-sensitivity detection of HBV-DNA levels reflects liver function deterioration in patients...

To investigate the clinical implication of quantitative polymerase chain reaction (PCR)-based high-sensitivity detection of hepatitis B virus (HBV)-DNA levels in patients with HBV-related liver cirrhosis (LC).

From January 2020 to December 2022, 100 fasting serum samples were collected and retrospectively analyzed from patients with treated HBV-related LC attending the Suzhou Hospital of Integrated Traditional Chinese and Western Medicine and Suzhou Guangci Cancer Hospital. Patients were divided into a negative group (HBV-DNA < 20 IU/mL) and a positive group (HBV-DNA ≥ 20 IU/mL) according to their high-sensitivity HBV-DNA test results. The clinical characteristics and serological indicators of the two groups were compared, mainly including gender, age, liver function [total protein (TP), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), total bilirubin (TBIL), direct bilirubin (DBIL), and indirect bilirubin (IBIL)], lipids [total cholesterol (TC) and triglycerides (TG)], platelets (PLT), five serum liver fibrosis markers [cholyglycine (CG), hyaluronic acid (HA), laminin (LN), precollagen type III (PCIII), and type IV collagen (IV-C)], serum gastrointestinal tumor markers [α-fetoprotein (AFP) and carcinoembryonic antigen (CEA)], and hepatitis B surface antigen (HBsAg). The differences between the two groups in terms of liver function Child-Pugh grades and the incidence of hepatocellular carcinoma (HCC) were also compared.

There were 39 patients in the positive group, including 29 males and 10 females, and 61 patients in the negative group, including 38 males and 23 females, with no statistically significant differences in gender and age distribution between the two groups (P > 0.05). The levels of serological indicators (TP, ALB, AST, GGT, ALP, TBIL, DBIL, IBIL, TC, TG, PLT, CG, HA, LN, PCIII, IV-C, AFP, CEA, and HBsAg) in both groups showed no significant differences (P > 0.05), but the ALT level in the positive group was higher than that in the negative group (P < 0.0001). The positive group had worse Child-Pugh grades and higher HCC incidence compared to the negative group (P < 0.0001, P = 0.028).

Patients with HBV-related LC and HBV-DNA ≥ 20 IU/mL have higher serum ALT levels, worse liver function Child-Pugh grades, and higher HCC incidence than those with HBV-DNA < 20 IU/mL. High-sensitivity HBV-DNA quantification can reflect the deterioration of liver function in patients with HBV-related LC to some extent.
