How I treat iron‐refractory iron deficiency anaemia—An expert opinion‐based treatment guidance for children and adults

open access: yesBritish Journal of Haematology, Volume 206, Issue 4, Page 1067-1076, April 2025.
In iron‐refractory iron deficiency anaemia, inappropriately elevated hepcidin levels impair enteral iron absorption and iron release from macrophages by interacting with ferroportin. Oral iron supplements (containing ~30 mg Fe2+ per 100 mg) are generally ineffective due to this hepcidin–ferroportin interaction although, in some cases, this can be ...
