The main purpose of this longitudinal study is to point out the effect of VitabranE on the ESA resistance and on the anemia observed in HD patients undergoing EPO maintenance therapy.

As a secondary purpose we will consider the effect of VitabranE on inflammation and oxidative stress parameters as a function of the changes observed in the anemia parameters.

Primary Outcome Measures:
  • The primary outcome measure will be the ESA resistance index, a combined variable calculated by dividing the weekly ESA dose by haemoglobin level and end-dialysis body weight. [ Time Frame: every other month ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Inflammatory status (CRP and IL-6) and oxidative stress markers (Vitamin E levels, TAC, Protein carbonyls and AOPP, AGEs). [ Time Frame: every other month ] [ Designated as safety issue: No ]

Enrollment: 20
Study Start Date: July 2006
