title: Blood cell, liver function, and response changes by PEG-interferon-alpha2b plus ribavirin with polaprezinc therapy in patients with chronic hepatitis C.
abstract: OBJECTIVE
  Zinc has been reported to ameliorate hematologic side effects and improve liver function. In addition to its various effects, zinc supplementation in chronic hepatitis C patients with genotype 1b of high viral load enhanced the response to interferon (IFN) monotherapy. This study was aimed at clarifying whether zinc could improve hematologic side effects, improve liver function, and enhance the response to therapy in patients with chronic hepatitis C treated with pegylated-interferon (PEG-IFN) plus ribavirin (RBV).
  
  
  METHODS
  The 32 patients enrolled in the study were randomly divided into two groups: a PEG-IFN-alpha2b plus RBV with zinc group (PEG/RBV + zinc, n = 16) and a PEG-IFN-alpha2b plus RBV group (PEG/RBV, n = 16). HCV-RNA, serum zinc, ALT, white blood cell, red blood cell, platelet, and hemoglobin (Hb) levels were examined.
  
  
  RESULTS
  Serum zinc levels were significantly higher in the PEG/RBV with zinc group than in the PEG/RBV without zinc group at 4, 8, and 12 weeks. No significant differences were observed in the clearance of HCV-RNA between the two groups. The outcome of the treatment was similar; results of laboratory examinations including ALT before, during, and after therapy revealed no significant differences between the two groups at any point in all items except serum zinc levels. A sustained virological response rate was observed in 50.0% in the PEG/RBV with zinc group and 43.8% in the PEG/RBV without zinc group, with no significant difference between the two groups.
  
  
  CONCLUSIONS
  The study demonstrated no evidence that zinc ameliorates hematologic side effects, improves liver function, and enhances the response to the therapy in chronic hepatitis C receiving PEG-IFN-alpha2b plus RBV.
