Radioiron excretion in the urine and feces after continuous subcutaneous infusion of desferrioxamine (DF) was studied in normal and hypertransfused rats in whom reticuloendothelial and parenchymal iron stores had been labeled by selective 59Fe probes. The existence of two alternative pathways for the chelation of iron in vivo by DF was indicated by the results. The first pathway was intracellul...

Background: One of the most common endocrine problems in major beta-thalassemia is hypothyroidism (HT). The aim of this study was to evaluate thyroid function status in major beta-thalassemia patients older than 10 years old. Methods: This cross sectional study was carried out on thalassemia major patients registered on Thalassemia Center of Amirkola Children Hospital in Babol. A questionnaire ...

Myelodysplastic syndromes (MDS) are a heterogeneous disorder of the hematopoietic stem cells, frequently characterized by anemia and transfusion dependency. In low-risk patients, transfusion dependency can be long lasting, leading to iron overload. Iron chelation therapy may be a therapeutic option for these patients, especially since the approval of oral iron chelators, which are easier to use...

When Policy Topic is covered A number of indications for chelation therapy have received Food and Drug Administration (FDA) approval and for which chelation therapy is considered standard of care treatment. They include:  extreme conditions of metal toxicity;  treatment of chronic iron overload due to blood transfusions (transfusional hemosiderosis) and due to non-transfusion-dependent thalas...

Background: The antioxidant components have been identified in some pine species. Antioxidant properties of proantocyanidins reduce free radicals induced by DNA fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. Objective: In this study, we analyzed different parts of Pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. ...

OBJECTIVES There is a need to remove excess iron with iron chelation therapy (ICT) to avoid the serious clinical sequelae associated with iron overload in patients with beta thalassemia major (BTM) and sickle cell anemia (SCA). Due to the effects of the diseases and their treatments, ICT is still a major reason for unsatisfactory compliance. The aim of this single-center observational study was...

BACKGROUND In beta-thalassemia, profound anemia and severe hemosiderosis cause functional and physiological abnormalities in various organ systems. In recent years, there have been few published studies mainly in adult demonstrating renal involvement in beta-thalassemia. This prospective study was aimed to investigate renal involvement in pediatric patients with transfusion dependent beta-thala...

OBJECTIVES The purpose of this study was to evaluate the effect of chelation therapy with ethylenediamine tetraacetic acid (EDTA) on endothelium-dependent vasomotor responses in patients with documented coronary artery disease (CAD). BACKGROUND Oxidative stress plays an important role in the dysfunction of endothelium and development of atherosclerosis. Modification of cardiac risk factors an...
