transferrin by iron-binding capacity
SYNOPSIS Two criteria which ought to be satisfied by an acceptable method for the estimation of serum transferrin by iron-binding capacity are enunciated. A screening procedure is described which involves the sequential quantitative use of ion exchange and gel filtration. Its use in testing the extent to which two published methods fulfil the recommended criteria is described. Both methods give...
متن کاملTimed non-transferrin bound iron determinations probe the origin of chelatable iron pools during deferiprone regimens and predict chelation response.
BACKGROUND Plasma non-transferrin bound iron refers to heterogeneous plasma iron species, not bound to transferrin, which appear in conditions of iron overload and ineffective erythropoiesis. The clinical utility of non-transferrin bound iron in predicting complications from iron overload, or response to chelation therapy remains unproven. We undertook carefully timed measurements of non-transf...
متن کاملOral iron chelating therapy. A single center interim report on deferiprone (L1) in thalassemia.
BACKGROUND AND OBJECTIVE Deferiprone (L1) is a largely studied oral chelator in clinical setting, however, no definite conclusions concerning efficacy and toxicity still could be drawn. In an ongoing prospective trial with L1, we evaluated the efficacy and tolerance-toxicity in patients with thalassemia major previously treated by desferrioxamine (DFO); the specific aim of the study is to demon...
متن کاملChelation therapy in patients with thalassemia using the orally active iron chelator deferiprone (L1).
BACKGROUND AND OBJECTIVE Excessive hemosiderosis is the main reason for the multi-organ failure observed in multitransfused patients. Deferiprone (1,2-dimethyl-3-hydroxy-pyridine-4-one, L1) is an orally active iron chelator mainly excreted via urine. We conducted a study in order to determine the efficacy and safety of L1 in Greek thalassemic patients. DESIGN AND METHODS A group of 11 thalass...
متن کاملEndosome–mitochondria interactions are modulated by iron release from transferrin
Transient "kiss and run" interactions between endosomes containing iron-bound transferrin (Tf) and mitochondria have been shown to facilitate direct iron transfer in erythroid cells. In this study, we used superresolution three-dimensional (3D) direct stochastic optical reconstruction microscopy to show that Tf-containing endosomes directly interact with mitochondria in epithelial cells. We use...
