Iron overload in transfusion‐dependent patients with haemolytic diseases is associated with inappropriate hepcidin levels. (A–D) Measurement of haemoglobin, erythropoietin (EPO), hepcidin and hepcidin–serum ferritin (Ft) ratio in blood samples and sera of healthy subjects (Ctrl), and patients with β‐thalassaemia (β‐thal) intermedia (int) and major; (E–H) Measurement of haemoglobin, EPO, hepcidin and hepcidin–Ft ratio in sera of Ctrls, as well as patients with sickle cell disease (SCD 1 and 2) and spherocytosis (SPH). EPO is shown only in the SPH an SCD 1 groups. Values represent mean ± SD. *P < 0·05; ***P < 0·001; ****P < 0·0001.
