Summary
Hepatitis B virus (HBV) carriers show elevated neopterin levels, indicating immune activation and potential liver inflammation. This suggests cellular immunity plays a role even with low viral loads.
Area of Science:
- Immunology
- Hepatology
- Virology
Background:
- Hepatitis B virus (HBV) infection is a global health concern.
- Immune activation markers can indicate disease progression.
- Neopterin is a marker of cellular immune system activation.
Purpose of the Study:
- To investigate immune activation in Hepatitis B virus carriers with low viral load.
- To measure neopterin levels in HBV carriers and healthy controls.
- To explore the relationship between neopterin levels and cellular immunity in HBV infection.
Main Methods:
- Comparative study design.
- Recruitment of 43 HBV carriers and 56 healthy controls.
- Measurement of serum neopterin, ALT, ALP, AST, and GGT levels.
Main Results:
- HBV carriers exhibited significantly higher neopterin levels (159.97+/-13.39 nmol/l) compared to controls (84.10+/-11.45 nmol/l) (P<0.0001).
- Minor elevations in liver enzymes (ALT, ALP, AST) were observed in a few patients.
- GGT levels remained within the reference range for all participants.
Conclusions:
- Elevated neopterin levels in HBV carriers suggest underlying immune activation.
- Increased neopterin may indicate a background of cellular immune-driven inflammation in the liver.
- Neopterin serves as a potential biomarker for monitoring immune status in HBV infection.
