Abstract: Objective The aim of this study was to explore the implication of serum soluble vascular adhesion protein-1 (sVAP-1) and serum amyloid A (SAA) levels in patients with chronic hepatitis C (CHC) receiving pegylated interferon α-2a (peg-IFN-α-2a) and ribavirin standardized treatment. Methods 62 patients with CHC and 48 healthy persons were enrolled in our hospital between February 2018 and February 2022, and all patients with CHC were treated with peg-IFN α-2a and ribavirin for 24 weeks. Serum sVAP-1 and SAA levels were detected by ELISA, and serum HCV RNA load was detected by real-time fluorescence quantitative PCR. The virologic response was evaluated by early virologic response (EVR), end treatment virologic response (ETVR) and sustained virologic response (SVR). Results Serum sVAP-1 and SAA levels in patients with CHC were (164.0±29.3)μg/L and (3.0±0.6)mg/L, significantly higher than [(73.7±15.8)μg/L and (0.8±0.2)mg/L, P<0.05] in healthy persons; serum sVAP-1 and SAA levels in 17 CHC patients with high serum viral loads were (225.9±33.7)μg/L and (4.3±0.7) mg/L, significantly higher than [(156.7±28.4)μg/L and (3.0±0.5)mg/L, respectively, P<0.05] in 26 CHC patients with medium viral loads or [(118.7±22.0)μg/L and (1.8±0.3)mg/L, respectively, P<0.05] in 19 CHC patients with low viral loads; serum SAA levels in patients who responded to antiviral therapy were significantly higher than non-responders [EVR:(4.1±0.7)mg/L vs. (2.2±0.5)mg/L; ETVR:(3.2±0.9)mg/L vs. (1.6±0.4)mg/L and SVR:(3.7±0.8)mg/L vs.(1.5±0.4)mg/L, P<0.05], while there were no significant differences as respect to serum sVAP-1 levels between responders and non-responders (P>0.05). Conclusion Serum sVAP-1 and SAA levels in patients with CHC increase, and their changes are related to virus replication. It might be helpful by monitoring serum SAA level changes in predicting the antiviral efficacy in patients with CHC.
