BACKGROUND AND OBJECTIVES Effective and convenient iron chelation remains one of the main targets of clinical management of thalassemia major. The combined treatment with desferrioxamine and deferiprone could have an increased chelation efficacy and sometimes allow drug doses and toxicity to be reduced and the number of days of desferrioxamine infusion to be decreased, improving compliance and ...
Iron is a limiting nutrient for Symbiodiniaceae (colloquially known as zooxanthellae), with low solubility in seawater. The use of stable, soluble, and chemically defined iron complexes proposed strategy to control the supply this metal target organisms. In work, we investigated effect iron(II) derivatives iron(III) (desferrioxamine, deferiprone, deferasirox, HBED) over growth loading five spec...
The effect of desferrioxamine is examined in more than 100 patients with liver disease, including haemochromatosis, using the differential ferrioxamine test. The procedure gives a reasonably accurate estimate of the size of the iron stores, as determined by multiple venesection, in patients with idiopathic haemochromatosis. Since desferrioxamine is not specific for storage iron, unequivocally a...
Desferrioxamine, widely used for the treatment of iron overload in Cooley's anaemia, binds iron so tightly that it should quantitatively remove iron from transferrin. Studies conducted in vivo and in vitro, however, have failed to demonstrate significant depletion of transferrin-bound iron by a stoichiometric excess of desferrioxamine. However, low molecular weight chelating agents, capable of ...
Twenty-eight children with beta-thalassaemia major aged between 11 and 48 months were given intensive transfusions. Serum iron, transferrin saturation, serum ferritin, non-transferrin iron, and subcutaneous desferrioxamine-induced urinary iron excretion were measured. The results showed that even children with a limited number of transfusions had severe iron overload as indicated, in particular...
INJURY to the cornea with an iron-containing foreign body usually leaves a rust ring. Most surgeons advise complete removal of any rust, but this often causes considerable trauma to the already injured cornea. Desferrioxamine ("Desferal", Ciba Laboratories) is an iron-free compound isolated from a strain of Streptomycespilosus, which binds ferric ions to form an octahedral complex ferrioxamine....
Vascular smooth muscle cell (VSMC) growth is a primary component of accelerated and spontaneous atherosclerosis. Previous studies have shown that iron may be involved in the control of enzymatic activities that modulate DNA synthesis in human cells. In this study the effects of the iron chelator desferrioxamine on in vitro and in vivo VSMC proliferation were tested. Rat VSMCs in culture and a r...
Background and Purpose: Cardiac complications in major thalassemia are the most debilitating problem among them. Iron chelating with desferrioxamine, may be difficult or inadequate. The aim of this research is to evaluate the effect of combination therapy with the two drugs "deferiprone & desferrioxamine" on cardiac complications in major thalassemia. Materials and Methods: In a clinical t...
BACKGROUND: Beta thalassemia major requires regular blood transfusions and iron chelation to alleviate the harmful accumulation of iron. Evidence on the efficacy and safety of the available agents, desferrioxamine and deferiprone, is derived from small, non-comparative, heterogeneous observational studies. This evidence was reviewed to quantitatively compare the ability of these chelators to re...
