  Purpose

Vitamin D deficiency is commonly found in patients with chronic hepatitis C. The investigators hypothesize that the correction of hypovitaminosis D before the initiation of anti-HCV combination therapy and the maintenance of an optimal vitamin D status during antiviral therapy could improve the antiviral efficacy

Primary Outcome Measures:
  • Negativity of HCV RNA below 12UI/mL after 12 weeks of antiviral combination therapy [ Time Frame: at week 12 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

  • Changes in HCV viral load (delta log) [ Time Frame: at week 4 ] [ Designated as safety issue: No ]
  • Changes in HCV viral load (delta log) [ Time Frame: at week 12 ] [ Designated as safety issue: No ]
  • Negativity of HCV RNA below 12 UI/ml [ Time Frame: at week 24 ] [ Designated as safety issue: No ]
  • Negativity of HCV RNA below 12 UI/ml [ Time Frame: at week 72 ] [ Designated as safety issue: No ]

Vitamin D on top of the standard treatment

Detailed Description:

An open-label, prospective evaluation of the efficacy of vitamin D supplementation starting 1 month before and continuing for the duration of combination therapy with pegylated interferon alpha (2a or 2b) plus ribavirin in patients with chronic viral hepatitis C genotype 1 or 4, nonresponders to a first antiviral therapy.Vitamin D supplementation is started one month before antiviral therapy in order to introduce pegylated interferon plus ribavirin in patients with optimal vitamin D status
