This study was conducted to determine the clinical relevance of hepcidin, a recently identified key iron regulatory hormone, in patients with chronic hepatitis C virus (C-HCV).


Serum hepcidin levels were measured in 9 C-HCV patients by surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS), and compared to those of healthy controls. Sequential changes of hepcidin were also investigated during phlebotomy.


Serum hepcidin and ferritin were significantly higher in C-HCV than in controls (P = 0.0002), these two variables were strongly related to each other (r = 0.658; P < 0.01), and phlebotomy significantly decreased serum hepcidin in C-HCV (P = 0.0007); all these results recollect the hepcidin response to iron signal. Hepcidin/ferritin ratio, an index of the appropriateness of hepcidin expression relative to iron overload, was significantly lower in C-HCV than in controls (0.33 ± 0.41 vs. 0.73 ± 0.36, P = 0.0068). This relative impairment of hepcidin expression was not reversible after phlebotomy (P = NS).


Although the hepcidin expression responds to iron conditions in C-HCV, this response is relatively limited. This relative impairment of hepcidin expression may be relevant to disease progression, and thus correction of its regulation may be beneficial for these iron-overloaded C-HCV patients.
