To the Editor,

We read with great interest the published re­port by Souqiyyeh et al about Survey of attitude of physicians on updates in the management of anemia in chronic kidney disease patients. [1] The authors' results showed inadequate awareness of physicians of the mechanisms of action of ESAs and the new agents such as the CERA. Anemia is a severe and common complication of chronic kidney disease (CKD seen in more than 80% of patients with impaired renal func­ion. [2] Despite the successes of epoetin alfa and darbepoetin alfa, the management of anemia of CKD is poised for further clinical advancement. Several new anemia therapies are in various stages of development. There are still shades of grey in the treatment of CKD related anemia. CREATE and CHOIR were 2 recent pivotal trials that suggested that hemoglobin levels may largely impact cardiovascular outcomes. [3],[4] Both of these trials assessed the impact that the correction of anemia had on the occurrence of cardiovascular events in patients with CKD. [3],[4] Lack of knowledge and awareness of the me­chanism of action of the protein ESAs, the half-life and the dosing interval of the ESAs and data of the other nonprotein agents is one of the contributory factor behind inadequate response in managing CKD related anemia. Most common cause of erythropoietin hypo­responsiveness is actually pseudohyporespon­siveness related to inadequate dosing and in­correct interval.

Apart from this, it will be interesting to check awareness about biosimilars, especially in de­veloping countries like India where biosimilars are freely available at a cheaper cost and awareness of batch-to-batch variability in ma­nufacturing of many such ESAs. Awareness of black box warnings given by FDA like, in­creased mortality, serious cardiovascular and thromboembolic events, and increased risk of tumour progression or recurrence need to be checked as well.
