In Iron Deficiency anaemia, Iron is the required fuel for the production of new red blood cells and Erythropoietin is the accelerator that drives
erythropoiesis. When the two are coupled, red cell production moves briskly and efficiently.
Hepcidin levels increase in the presence of inflammation, reducing the amount of iron available for
erythropoiesis both by locking up iron and by decreasing the amount of iron absorbed from the duodenum.
A dose-finding and safety study of novel
erythropoiesis stimulating protein (NESP) for the treatment of anaemia in patients receiving multicycle chemotherapy.

Erythropoiesis Receptor Activator (CERA)
Functional iron deficiency (or iron-restricted
erythropoiesis) is seen in healthy individuals with apparently normal iron stores.
The team believed other factors that influenced this success included better control of the inflammatory processes and more frequent treatment of iron-restricted
erythropoiesis with ESA therapy.
The hemoglobinization of erythrocytes is used to detect functional ID because the Hb content of reticulocytes and erythrocytes provides an evaluation of the bone marrow activity, reflecting the balance between iron and
erythropoiesis (3).
Moreover, during ineffective
erythropoiesis and observations on thalassemia patients the growth differentiation factor 15 (GDF15) and twisted gastrulation 1 (TWSG1) are two transforming growth factor-beta (TGF) family products produced and they likewise down-regulate hepcidin.
ASCEND-ND (Anaemia Studies in CKD:
Erythropoiesis via a Novel PHI Daprodustat-Non-Dialysis) will enrol approximately 4,500 non-dialysis dependent patients with anaemia associated with CKD and will include patients either switching from or naive to an ESA.
The clinical manifestations of thalassemia intermedia result from ineffective
erythropoiesis, chronic anemia, and iron overload.
The reticulocyte haemoglobin equivalent (RET_He) is a red cell parameter available on the XN-2000 and other Sysmex haematology analysers and provides a measure of the bioavailability of iron during
erythropoiesis (4,5).
