Summary

People with kidney failure are at risk for the development of anemia. Anemia is a decrease in the production of hemoglobin, a substance that carries oxygen in the blood. The majority of patients require erythropoietin and iron supplementation to correct the anemia. In some patients, the hemoglobin fails to rise to a desired level despite treatment with erythropoietin and iron. There have been several studies in hemodialysis patients showing that vitamin C given intravenously helps to correct anemia in patients already on erythropoietin and iron.

The purpose of this study is to determine whether oral vitamin C will improve parameters of anemia in patients receiving peritoneal dialysis.

Description of the research

This is a randomized, double blind, placebo controlled study. Participants will be randomized in a 1:1 ratio to oral vitamin C 500mg once a day or placebo for 3 months. All participants will be receiving oral iron supplementation, subcutaneous erythropoietin and a B and C complex vitamin containing 100mg of vitamin C. Lab parameters (hemoglobin, TSAT, ferritin) will be done at baseline and then monthly. The primary outcome is percent change from baseline in transferrin saturation. Secondary objectives are percent change in ferritin, hemoglobin and erythropoietin dose from baseline.
