BACKGROUND Some epidemiological studies have shown that increased iron stores are associated with increased cardiovascular events. Redox-active iron may contribute to lipid peroxidation, endothelial cell activation, and generation of reactive oxygen species (especially hydroxyl radical, via Fenton chemistry). Increased oxidative stress is associated with impaired action of endothelium-derived n...
Background: Iron is an essential mineral for normal cellular physiology but its overload can lead to cell injury. For many years, deferoxamine injection has been used as an iron chelator for treatment of iron overload. The aim of this study is to compare oral deferoxamine, activated charcoal, and vitamin C, as an absorbent factor of Fe, in changing the serum level of iron in iron overload rats....
Most deaths in beta-thalassemia major result from cardiac complications due to iron overload. Differential effects on myocardial siderosis may exist between different chelators. A randomized controlled trial was performed in 61 patients previously maintained on subcutaneous deferoxamine. The primary end point was the change in myocardial siderosis (myocardial T2*) over 1 year in patients mainta...
Iron resulting from hemoglobin degradation is linked to delayed neuronal injury after intracerebral hemorrhage. Extensive preclinical investigations indicate that the iron chelator, deferoxamine mesylate, is effective in limiting hemoglobin- and iron-mediated neurotoxicity. However, clinical studies evaluating the use of deferoxamine in intracerebral hemorrhage are shortcoming. This article rev...
Deferoxamine, a clinically safe drug used for treating iron overload, also repairs spinal cord injury although the mechanism for this action remains unknown. Here, we determined whether deferoxamine was therapeutic in a rat model of spinal cord injury and explored potential mechanisms for this effect. Spinal cord injury was induced by impacting the spinal cord at the thoracic T10 vertebra level...
Effect of Deferoxamine on Blood-brain Barrier Disturbances following Subarachnoid Haemorrage in Cats
Disruption of the blood brain barrier plays a significant role in the pathophysiology of subarachnoid haemorrhage. Experimental studies concerning subarachnoid haemorrhage suggested the primary role of free radicals and subsequently lipid peroxidation in the pathogenesis of vasospasm. In this experimental study the role of deferoxamine on blood brain barrier disturbance in vasospasm was evaluat...
Deferoxamine is widely used therapeutically as a chelator of ferric ion in disorders of iron overload. This study demonstrates that this drug is a potent inhibitor of DNA synthesis by human B and T lymphocytes in vitro, but has relatively little effect on the synthesis of RNA and protein. The inhibitory effects of deferoxamine are completely reversible by washing or by adding stoichiometric amo...
BACKGROUND Cardiac complications secondary to iron overload are the leading cause of death in beta-thalassemia major. Approximately two thirds of patients maintained on the parenteral iron chelator deferoxamine have myocardial iron loading. The oral iron chelator deferiprone has been demonstrated to remove myocardial iron, and it has been proposed that in combination with deferoxamine it may ha...
abstract background iron overload is a major problem in patients with major thalassemia. an effective and safe iron chelator protocol with high compliance rate plays an important role in treatment of these patients. this study was done to assess the efficacy and safety of the sequential deferoxamine and deferasirox protocol in major thalassemia patients in khuzestan province, iran. material and...
Several life-threatening complications of the common disorder sickle cell disease require management with red blood cell transfusions and, hence, long-term iron-chelating therapy. The efficacy of the oral iron chelator 1,2-dimethyl-3-hydroxypyrid-4-one (L1) has not previously been determined in patients with sickle cell disease. We compared the efficacy of L1 to that of standard-dose subcutaneo...
