Summary:Iron overload is a common acute and long-term event associated with autologous and allogeneic hematopoietic stem cell transplantation (HSCT). In a state of iron excess, free iron becomes available to catalyze the conversion of reactive oxygen species (ROS) intermediates such as superoxide anion (O2•−) and hydrogen peroxide (H2O2) to highly toxic free radicals such as hydroxyl radical (OH•). ROS may help to promote chronic liver disease, sinusoidal obstruction syndrome, idiopathic… 

Iron overload and allogeneic hematopoietic stem-cell

Iron-chelating therapy before and/or after transplantation is a promising strategy to improve the clinical outcomes of transplant patients with iron overload, but further research is needed to prove the direct relationship between iron overload and adverse outcomes.

The management of iron overload in allogeneic hematopoietic stem cell transplant (alloHSCT) recipients: Where do we stand?

Iron overload, primarily related to multiple red blood cell transfusions, is a relatively common complication in hematopoietic stem cell transplant (HSCT) recipients and efforts have been directed toward identifying alternative treatment for IO in alloHSCT recipients to maintain improved transplant outcomes.

Disturbance of pro-oxidative/antioxidative balance in allogeneic peripheral blood stem cell transplantation.

There is a significant disturbance of pro-oxidative/antioxidative balance in the plasma of patients undergoing allogeneic HSCT regardless of the intensity of the conditioning regimen, and their relationships with graft-versus-host disease, conditioning regimens, and transplant-related mortality are investigated.

Iron overload, hematopoietic cell transplantation, and graft-versus-host disease

Many patients who undergo hematopoietic cell transplantation (HCT) present with anemia and have received red blood cell transfusions before HCT. As a result, iron overload is frequent and appears to

Iron Overload and Hematopoetic Stem Cell Transplantation

Hematopoietic stem cell transplantation is an established treatment modality with a curative potential in a variety of hematological disorders and IO has a substantial role as a contributor to quality of life.

Iron Overload in Patients Undergoing Hematopoietic Stem Cell Transplantation

Accumulating evidence has established the negative impact of elevated pretransplantation serum ferritin, a surrogate marker of iron overload, on overall survival and nonrelapse mortality after HSCT, and particular attention should be paid to prevention and management in allogeneic HSCT candidates, especially in patients with thalassemia and myelodysplastic syndromes.

It is concluded that allogeneic T cells stimulate macrophage-derived reactive oxygen/nitrogen species, and that the addition of Cy favors peroxynitrite formation, which clarifies the dependence of Cy-induced lung injury and lethality on the presence of allogeneIC T cells.

Interestingly, toxicity does not necessarily correlate with Fe‐binding affinity or with chelation efficacy, suggesting that other factors may promote the cytopathic effects of chelators.
