What is it about?

Hyporesponsiveness to ESA may be directly evaluated as the dose of DA divided by Hb level at the 12th weeks of DA treatment. The cut-off value of the index was 5.2.

Why is it important?

ND-CKD patients with this index higher than 5.2 may have a higher risk for renal and CVD events in ND-CKD patients. A search for the causes of the poor response and measures for them should be recommended in such patients.

Perspectives

This index can be used to help make decisions such as changing from ESAs to HIF-PH inhibitors as treatment for renal anemia in ND-CKD.
