Core Tip
Core tip: Although several mechanisms for the favorable effects of vitamin D3 (VitD3) supplementation were reported, the total effect of VitD3 supplementation remains unclear. Recently, the main treatment of chronic hepatitis C should be direct acting antivirals (DAAs) without pegylated interferon (Peg-IFN). Peg-IFN is a strong immune-modulator. Therefore, an immunological analysis should be carried out to understand the effect of VitD3 after treatment of DAAs without Peg-IFN. The induction of a favorable immune response by adding VitD3 might be able to suppress the hepatocarcinogenesis after achieving SVR, especially in children and elderly patients with severe fibrosis lacking sufficient amounts of VitD3.
