A correlation analysis of the serum hepcidin concentrations and viral loads in HCV-infected patients.

OBJECTIVE:To investigate the correlation between the serum hepcidin levels and the viral loads in hepatitis C virus (HCV) infected patients. METHODS:Sixty HCV-infected patients (the study group) and 50 healthy controls (the control group) were recruited as the study cohort. The liver function and inflammation-related parameters were compared, and the 60 HCV patients were divided into mild (G1-G2), moderate (G3), and severe (G4) groups according to each patient's inflammatory activity grade (G). The serum iron (SI), ferritin (SF), and transferrin (TRF), hepcidin levels were compared. The relationships between the HCV-RNA, HCV Ag, HCV Ab, albumin (ALB), total bilirubin (TBIL), aminotransferase (ALT), and aspartate aminotransferase (AST) levels and the hepcidin levels was analyzed. The SI, SF, IL-6, ALT, AST, and TBIL levels were significantly higher, and the hepcidin, TRF, and ALB levels were significantly lower in the study group than they were in the control group (P<0.05). The G4 patients' SI and SF levels were significantly higher than they were in the G3 and the G1-G2 groups (P<0.05). The TRF and hepcidin levels in the G1-G2 group were significantly higher than they were in the G3 and G4 groups (P<0.05). The HCV-RNA, HCV Ag, and HCV Ab levels were negatively correlated with the hepcidin levels (r=-0.7679, r=-0.9062, r=-0.6095, P<0.05), positively correlated with the serum ALB, TBIL, and ALT levels (r=0.9792, r=0.9759, r=0.8236, P<0.05), and not significantly correlated with the AST levels (r=-0.2803, P>0.05). CONCLUSION:The HCV patients' serum hepcidin levels showed an abnormal decrease, suggesting that HCV patients may have an iron metabolism disorder, which indicates that there is a possibility of evaluating the HCV patients' conditions by measuring the hepcidin levels and of improving HCV patients' prognoses by regulating the iron metabolism.
