Introduction: Patients with end-stage kidney disease (ESKD) suffer from functional iron deficiency where despite the presence of sufficient iron stores in the body, adequate iron is unavailable for heme synthesis. This study hypothesis was that in patients undergoing hemodialysis (HD), administration of intravenous (IV) ascorbic acid (AA) exerts a good effect on the management of anemia, either by increasing the mobilization of iron from tissue stores or acting as an antioxidant to overcome the inflammatory block and increase the erythropoietin sensitivity. Methods: Fifty patients with ESRD who were on regular HD were included in the study. Patients' ferritin levels ranged from 500 to 1200 ng/mL with transferrin saturation of 30% or more. However, all patients were anemic and received erythropoietin therapy. Iron therapy was discontinued in the first group, whereas it was continued in the second group that received IV AA. Results: A significant increase in the levels of Hb was observed in the second group after 6 months despite the decrease in ferritin levels in both the groups. Transferrin saturation decreased in both groups, the decrease being more in the first group. The levels of C-reactive protein (CRP) decreased in the second group, whereas these increased in the first group. Conclusions: Intravenous AA as an adjuvant therapy with iron exerts a favorable and significant effect on the Hb, serum ferritin, and CRP levels in patients with ESKD having anemia. The discontinuation of iron therapy only decreases the serum ferritin levels and does not improve the Hb or CRP levels.
