Anemia

In the current prospective, double-blind, and randomized trial, 66 patients with peritoneal dialysis were enrolled, and 43 patients were detected with serum vitamin C level below 4 μg/ml to determine the effect of vit C on anemia in patients on CAPD.
The measured clinical parameters including plasma vitamin C level, hemoglobin (Hb), Ferritin, total iron-binding capacity (TIBC), serum Fe, C-reactive protein (CRP), and transferrin saturation. Consumption of vitamin supplements such as vitamin C (or any other form of it) either oral or parenteral were discontinued three weeks before collecting the samples.

vitamin c

Active (ascorbic acid 250 mg) and placebo (same weight of starch) tablets were similar in shape and size for both study and control groups. Intravenous intervention was not advantageous for hemodialysis subjects and it was impossible for PD patients, therefore, oral administration was used. All follow-up records were stored.
The erythropoietin (EPO) injections was prescribed for each patient in weekly dose, started one month before collecting blood samples for vitamin C measurement.

To evaluate the ability of oxidative stress markers to predict postoperative atrial fibrillation in subjects undergoing cardiac surgery.

Approximately 10- 15 ml of blood will be drawn from subjects. Blood samples will be separated into plasma and serum to measure the oxidative stress markers.
