Insights
Vascular adhesion protein-1 (VAP-1) levels increase with fibrosis severity in chronic hepatitis B patients, suggesting VAP-1 as a biomarker for fibrogenesis. Levels were higher in CHB than CHC patients.
Area of Science:
- Hepatology
- Biomarker Discovery
- Immunology
Background:
- Vascular adhesion protein-1 (VAP-1) is implicated in chronic liver diseases and fibrogenesis.
- Understanding VAP-1's role in disease progression is crucial for developing noninvasive diagnostic tools.
Purpose of the Study:
- To investigate the association between VAP-1 levels and the severity of fibrosis, cirrhosis, and hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) and C (CHC) patients.
- To evaluate VAP-1 as a potential noninvasive biomarker for monitoring liver disease progression.
Main Methods:
- Serum VAP-1 concentrations were measured using ELISA in CHB and CHC patients across different fibrosis stages (F0-F4), cirrhosis, and HCC.
- VAP-1 levels were compared between fibrosis stages and disease types.
Main Results:
- VAP-1 levels significantly increased with fibrosis progression in CHB patients, peaking at stage F4 (severe fibrosis).
- A significant difference in VAP-1 was observed between F0 and F4 in CHB, but not between F1 and F4 in CHC.
- No significant difference in VAP-1 levels was found between cirrhosis and HCC patients for either CHB or CHC.
- VAP-1 levels were generally higher in CHB than in CHC patients.
Conclusions:
- VAP-1 levels may serve as a noninvasive biomarker for assessing fibrogenesis severity in chronic hepatitis B infection.
- Further research is warranted to explore VAP-1's utility in CHC and its correlation with other liver disease markers.
Abstract:
Vascular adhesion protein-1 (VAP-1) is a multifunctional protein that plays a role in chronic liver diseases and fibrogenesis. The present study aimed to investigate the possible association of VAP-1 levels with the severity of disease progression in chronic hepatitis (CH) B and C patients with differing stages of fibrosis (F0-4), CHB/CHC-related cirrhosis, and hepatocellular carcinoma (HCC). The VAP-1 concentration in patient sera was determined by ELISA. The VAP-1 levels were compared between the F0 group and the F1, F2, F3, F4, cirrhosis, and HCC groups of CHB patients and between the F1 group and the F2, F3, F4, cirrhosis, and HCC groups of CHC patients. The levels of VAP-1 were significantly increased in CHB patients with progressive stages of fibrosis, with the highest concentration being found in those with stage F4 (severe fibrosis). A statistically significant difference was found between F0 and F4 in patients with CHB, but no statistically significant difference was observed between F1 and F4 in patients with CHC. Interestingly, there was no statistically significant difference in VAP-1 levels between patients with cirrhosis and HCC (either CHB or CHC, independently). Moreover, no relationship was found between VAP-1 and ALT levels in either CHC or CHB patients. In general, the VAP-1 levels were significantly higher in CHB than in CHC patients (P < 0.01). In conclusion, we suggest that the VAP-1 level may be a noninvasive biomarker for monitoring the severity of fibrogenesis in patients with hepatitis B infection.
