Insights
Retinol-binding protein 4 (RBP4) levels did not differ overall in hepatitis C virus (HCV) infection but correlated negatively with disease severity. RBP4 may serve as a biomarker for HCV progression.
Area of Science:
- Hepatology
- Biochemistry
- Clinical Medicine
Background:
- The association between retinol-binding protein 4 (RBP4) and hepatitis C virus (HCV) infection requires clarification.
- Understanding RBP4's role in HCV pathogenesis is crucial for potential therapeutic strategies.
Purpose of the Study:
- To systematically evaluate circulating RBP4 levels in patients with HCV.
- To investigate the correlation between RBP4 levels and HCV disease severity.
Main Methods:
- A systematic literature search was conducted across Embase, PubMed, and Cochrane databases up to January 1, 2024.
- Meta-analysis was performed on eight studies involving 2612 participants (1282 HCV patients, 1152 controls).
- PROSPERO registration: CRD42023489051.
Main Results:
- Overall RBP4 levels showed no significant difference between HCV patients and controls.
- A subgroup analysis of Asian participants revealed significantly lower RBP4 levels in HCV patients.
- A negative correlation was observed between RBP4 levels and HCV disease severity across populations.
Conclusions:
- RBP4 levels in HCV infection are influenced by factors like genotype, ethnicity, and environment.
- RBP4 levels appear to reflect disease progression severity in HCV patients.
- RBP4 shows potential as a biomarker for monitoring HCV disease progression, warranting further mechanistic research.
Abstract:
Background and Objectives: The relationship between circulating retinol-binding protein 4 (RBP4) levels and hepatitis C virus (HCV) infection remains unclear. This study aims to systematically assess RBP4 expression in patients with HCV and its correlation with disease severity. Materials and Methods: We searched the Embase, PubMed, and Cochrane databases for relevant studies up to 1 January 2024. This study was registered on PROSPERO (CRD42023489051). Results: Our analysis included eight studies with 2612 participants (1152 controls and 1282 patients with HCV). Overall, RBP4 levels did not significantly differ between patients with HCV and controls (SMD: -0.36; 95% CI: -0.94, 0.23; p = 0.23). However, in a subgroup of Asian subjects, patients with HCV showed significantly lower RBP4 levels (SMD: -0.40; 95% CI: -0.49, -0.31; p = 0.10). Additionally, a negative correlation between RBP4 levels and disease severity was observed across all studied populations. Conclusions: RBP4 levels may vary due to HCV genotype, ethnicity, and environmental factors. In the context of HCV infection, RBP4 levels appear to reflect the severity of disease progression. Our findings indicate that RBP4 could serve as a biomarker for HCV disease progression. Further research is needed to elucidate the complex mechanisms of RBP4 in HCV infection.
