HAMP and myelodysplastic syndrome: Despite the varying clinical characteristics observed in MDS patients and the differences in laboratory methods detailed in each paper, we drew the following conclusions: (1) although high serum hepcidin levels are linked to MDS, most studies generally found no significant difference in these levels between patients and healthy individuals; (2) serum hepcidin levels are specific to MDS type; (3) serum hepcidin levels in MDS are strongly associated with transfusions and the patient’s genetic status; (4) high-risk MDS is associated with high serum hepcidin levels.
