Efficacy of Ferric Carboxymaltose Versus Iron Sucrose in Non-dialysis Dependent Chronic Kidney Disease Patients

Anemia is a common complication of chronic kidney disease with its prevalence increasing with disease progression. The major causes of anemia in patients who have CKD are iron and erythropoietin deficiency. For management of iron deficiency either oral or intravenous iron products are used. Currently Iron Sucrose is being used as drug of choice for intravenous iron replacement for treatment of iron deficiency anemia as standard of care in Pakistan.

Objective of this study is to compare Ferric Carboxymaltose versus Iron Sucrose for treatment of iron deficiency anemia.

This study will be conducted at the department of Nephrology, Sindh Institute of Urology and Transplantation (SIUT), Karachi, Sindh, Pakistan. Data will be collected after taking approval of Institutional review board and Ethical review Committee and informed written consent from the participants.

Participants will be enrolled by principal investigator. All participants will be randomized into two groups by sealed envelopes.

After enrollment, participants will be administered either Ferric Carboxymaltose or Iron Sucrose at daycare clinic of department, Dose will be according to calculated iron deficit though Ganozi formula. Iron deficit(mg) = bodyweight(kg) x (target hemoglobin - actual hemoglobin ) (g/dl) x 2.4 + Iron storage depot(mg).

Medical problems (adverse effects) will be monitored, noted and treated accordingly.

Laboratory parameters such as hemoglobin, serum ferritin and transferrin saturation will be checked at baseline and scheduled visits, which will be compared at the end of study.

After completion of data collection, data analysis will be done using Statistical package for social sciences 26.
