Abstract
Objective
To explore the safety and efficacy of intravenous (IV) iron sucrose in maintenance peritoneal dialysis (PD).
Design
Randomized, controlled, parallel-group single-center trial.
Setting
Blood Purification Center of Chaoyang, Beijing Capital University of Medical Science, China.
Methods
46 patients on PD were involved in this trial. 26 patients received IV iron sucrose (200 mg iron) once per week for 4 weeks then once every other week for a further 4 weeks. The other 20 patients received oral ferrous succinate, 200 mg three times per day, for 8 weeks. Hemoglobin, hematocrit, serum ferritin (SF) level, and transferrin saturation (TSAT) were assessed at baseline and then again after 2, 4, and 8 weeks of treatment.
Results
There were no differences between the IV and oral groups in terms of sex, age, duration of PD, mean dialysate dosage per day, erythropoietin dosage per week, or hematological parameters at baseline. After 4 and 8 weeks of treatment, mean Hb and Hct were significantly increased in the IV group and were also significantly higher than those in the oral group. Levels of SF and TSAT were also significantly increased in the IV group, and significantly higher than in the oral group. After 8 weeks, the response rate in the IV group was 94.8%, which was significantly higher than that in the oral group. The mean erythropoietin dose was significantly lower in the IV group than in the oral group. Hb, Hct, SF, and TSAT levels were maintained between 4 and 8 weeks in the IV group despite the decrease in dose frequency. There were no adverse events with IV iron. Eight patients in the oral group had adverse gastrointestinal effects.
Conclusion
IV iron sucrose is safe in PD patients. It increases Hb levels and serum iron parameters more effectively than oral iron; it is well tolerated and can permit reductions in the required dose of erythropoietin.
