Anaemia in CKD is associated with reduced quality of life and increased cardiovascular disease, hospitalizations, cognitive impairment, and mortality. Correcting anaemia is considered an important part of slowing or even stopping the progression of CKD. Recombinant human erythropoietins (EPO) such as epoetin alfa are erythropoiesis-stimulating agents (ESAs) that are important treatment options. The ESA that is currently used in the hospital is Eprex®, a recombinant human EPO epoetin alfa which will soon be replaced by Binocrit®, a biosimilar ESA approved by the European Medicines Agency (EMA). We want to see whether maintenance of haemoglobin in stable ESRF patients would be affected by this switch in real life practice in the Malaysian population.
