Elevated Iron Chelating Activity of Ilex paraguariensis Leaf Infusion: in vitro and in vivo Pilot Studies

Abstract This study presents an Ilex paraguariensis leaf infusion with important potential as natural iron-chelating. The impact of infusion time and the water volume to obtain an Ilex paraguariensis leaf infusion with high phenolic content and iron chelating activity, such as the stability of these prop...

Treatment of iron overload syndrome: a general review

SUMMARY INTRODUCTION Iron overload is a broad syndrome with a large spectrum of causative etiologies that lead to iron deposition. When iron exceeds defenses, it causes oxidative damage and tissular disfunction. Treatment may prevent organ dysfunction, leading to greater life expectancy. METHODS Lite...

A avaliação da função renal é de extrema importância na prática clínica, tanto para o diagnóstico quanto para e prognóstico e monitoração das doenças renais. Neste contexto, aparticipação do laboratório é de grande importância, uma vez que a maior parte das doenças renais só se manif...

Protective effects of deferasirox and N-acetyl-L-cysteine on iron overload-injured bone marrow

Braz. j. med. biol. res; 50 (12), 2017
Using an iron overload mouse model, we explored the protective effect of deferasirox (DFX) and N-acetyl-L-cysteine (NAC) on injured bone marrow hematopoietic stem/progenitor cells (HSPC) induced by iron overload. Mice were intraperitoneally injected with 25 mg iron dextran every 3 days for 4 weeks to est...

Deferasirox-induced urticarial vasculitis in a patient with myelodysplastic syndrome

An. bras. dermatol; 92 (5,supl.1), 2017
Abstract Deferasirox is an iron chelator agent used in the treatment of diseases with iron overload, such as thalassemia and myelodysplastic syndrome. Although the majority of adverse reactions of deferasirox involve gastrointestinal symptoms and increase in serum creatinine and transaminases, skin rashe...

Evaluación de efectividad y seguridad de deferasirox en Hemosiderosis Transfusional
Evaluation of effectiveness and safety of deferasirox in Hemosiderosis Transfusional

Antecedentes: Descripción de la condición de salud de interés (indicación): El cuerpo humano no posee un mecanismo activo para la excreción de hierro, y sus niveles son controlados principalmente por su absorción en el intestino delgado. Fisiológicamente, la cantidad de hierro absorbido (1-2mg/dia...
