Anemia is one of the most common complications of Chronic Kidney Disease (CKD). The vast majority of Egyptian CKD patients are interchangeably treated with Darbepoetin Alfa (DPA) and Epoetin Alfa (EPA) to achieve and maintain target hemoglobin levels. Our study aimed to compare the efficacy and safety of DPA versus EPA for managing anemia amongst Egyptian patients with CKD undergoing dialysis. A multicenter, open label, randomized, prospective, parallel study was conducted. Patients with CKD undergoing dialysis with Hb level < 10 g/dl were enrolled. The primary efficacy endpoint was the change in hemoglobin concentration at the evaluation period (weeks 20-24). Prespecified adverse events of interest following administration, including blood transfusions requirement, blood pressure and hemoglobin excursions, the relationship between C - Reactive Protein (CRP) and hemoglobin, were assessed. Only 98 of 104 enrolled patients completed the study, fifty patients received EPA, and 48 patients received DPA. Our results showed that a significantly higher percentage of patients who achieved target Hb level ≥ 11 g/dL in DPA treated group vs. EPA as well as the meantime to achieve Hb level ≥ 10 g/dL was shorter in DPA treated group. Safety profiles of both treatments were similar. A negative correlation was observed between serum CRP and hemoglobin level in hemodialysis patients. Our study showed that DPA was more effective and well tolerated in achieving and maintaining Hb levels with lower dosing frequency compared to EPA. Furthermore, CRP is recommended to be routinely measured where patients with higher CRP require high ESA doses.
