After haematopoietic stem cell transplantation (HCT), many patients present anaemia, which can persist for months due to an inadequate erythropoietin production for the degree of the anaemia. In this thesis, we performed two randomised studies with erythropoiesis-stimulating agents therapy after allogeneic (including myeloablative and non-myeloablative conditioning) and autologous transplantation. We showed a great efficacy of this growth factor to ensure full erythroid reconstitution when initiated soon after engraftment and not immediately after the transplant. Furthermore, as iron parameters are quite disturbed following HCT, we sought to study iron metabolism after HCT (which has not been much investigated), integrating the role of hepcidin, the key regulator in iron metabolism. Hence, we demonstrated that hepcidin levels prior to and following autologous HCT were influenced by iron stores and changes in erythropoietic activity.
