ABSTRACT

Resumen OBJETIVO: Evaluar la eficacia y seguridad de la administración de altas dosis de hierro carboximaltosa en el tratamiento de pacientes con anemia ferropénica secundaria a hemorragia uterina anormal. MATERIAL Y MÉTODOS: Estudio cuasiexperimental de intervención, no controlado, con la variedad antes y después de un solo grupo (pretest-postest) efectuado en el Hospital Río de la Loza entre mayo de 2014 y septiembre de 2018. Criterios de inclusión: pacientes de 18 años o mayores con anemia y hemorragia uterina anormal severa. Criterios de exclusión: transfusión de concentrados eritrocitarios o administración de hierro parenteral en las ocho semanas previas al estudio, etc. Variables de estudio: hemoglobina, hematocrito, volumen corpuscular medio, concentración de hemoglobina corpuscular media, plaquetas y concentraciones de ferritina y plaquetas. RESULTADOS: Se analizaron los datos de 18 pacientes con anemia ferropénica secundaria a hemorragia uterina anormal 13 de 18 experimentaron un incremento de 2 g/dL o mayor de hemoglobina , 9 de 18 obtuvieron un incremento de 2.5 o mayor y solo 7 de 18 obtuvieron un incremento de 3 g/dL o mayor, los incrementos fueron dependientes de las dosis administrada. La ferritina sérica final promedio fue de 33.44 mcg/L. No hubo efectos adversos graves reportados. CONCLUSIONES: En este grupo de pacientes con anemia ferropénica, la administración de hierro carboximaltosa por vía intravenosa a dosis altas fue segura en la corrección de la carencia del mineral secundaria a hemorragia uterina anormal y en el reabastecimiento de los depósitos de hierro.


Abstract OBJECTIVE: The objective was to evaluate efficacy and safety of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose in correcting iron deficiency anemia due to abnormal uterine bleeding. MATERIAL AND METHODS: Quasi-experimental study of intervention, not controlled, with the variety before and after a single group (pretest-posttest) carried out in the Hospital Río de la Loza, Mexico, between May 2014 and September 2018. Inclusion criteria: patients 18 years of age or older with anemia and severe abnormal uterine hemorrhage. Exclusion criteria: transfusion of erythrocyte concentrates or administration of parenteral iron in the eight weeks prior to the study, etc. Study variables: hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration, platelets and concentrations of ferritin and platelets. RESULTS: 13 patients of 18 obtained an increase of 2 g/dL or greater of hemoglobin, 9 of 18 obtained an increase of 2.5 or greater and only 7 of 18 obtained an increase of 3g/dL or greater, the increases were dependent on the administered dose. The average final serum ferritin was 33.44 mcg/L. There were no serious adverse effects reported. CONCLUSIONS: The use of iron carboxymaltose intravenously at high doses is a safe treatment in the correction of iron deficiency anemia secondary to abnormal uterine hemorrhage and in the replenishment of iron stores.

ABSTRACT

A anemia ferropriva permanece como uma das deficiências nutricionais mais frequentes e importantes no mundo. O tratamento com ferro deve ser iniciado preferencialmente por via oral e a investigação apropriada de sua causa é obrigatória. Os autores discutem os compostos com ferro atualmente disponíveis, o perfil de eficácia, segurança e tolerabilidade desses medicamentos, e o plano terapêutico mais adequado possível para o sucesso no tratamento dessa doença tão comum e importante.


Iron deficiency anemia remains one of the commonest and most important nutritional deficiencies in the world today. The treatment of iron deficiency should preferably be initiated with oral iron; an appropriate investigation of the cause of iron deficiency anemia is mandatory. The authors discuss the currently available iron preparations as well as their efficacy, safety and tolerability and the optimal therapeutic plan to successfully treat this common and important disease.

ABSTRACT

Embora o ferro por via oral seja considerado a primeira opção de tratamento da deficiência de ferro, em algumas situações específicas, a administração de ferro por via parenteral é uma opção terapêutica que deve ser considerada. Diferentemente do ferro dextran de alto peso molecular utilizado na década de 80 e lembrado como um composto associado ao alto risco de reação anafilática e morte, o desenvolvimento e comercialização de novos compostos com ferro para uso parenteral, sobretudo por via endovenosa - como o ferro sacarato, ferro gluconato e, mais recentemente, a carboximaltose férrica - , tem se tornado cada vez mais uma alternativa terapêutica segura e efetiva, e tem possibilitado ampliar o leque de indicações desta modalidade de tratamento além da nefrologia, como obstetrícia e ginecologia, cirurgia, pediatria, gastroenterologia, hematologia e hemoterapia. Os autores revisam as principais indicações do tratamento com ferro por via parenteral, analisam as principais drogas disponíveis para a correção da anemia ferropriva por via endovenosa e propõem uma estratégia de investigação diagnóstica, tratamento e seguimento laboratorial dos pacientes com indicação desta opção terapêutica.


Although oral iron is generally considered the first choice in the treatment of iron deficiency, in some specific situations, parenteral iron administration is a therapeutic option that should be considered. Different to the high-molecular-weight iron dextran utilized in the eighties and remembered as a compound associated with a high risk of anaphylaxis and death, the development and marketing of newer preparations for parenteral, in particular endovenous, administration, such as iron sucrose, ferric gluconate and more recently ferric carboxymaltose, are becoming a more effective and safe therapeutic alternative, that have extended the range of indications beyond nephrology to obstetrics and gynecology, surgery, pediatrics, gastroenterology, hematology and hemotherapy. The authors review the main indications of parenteral iron treatment, analyse the drugs available for the correction of iron deficiency anemia by intravenous iron administration and propose a new strategy of diagnostic investigation, treatment and laboratory follow up of the patient with indication for this therapeutic option.

ABSTRACT

A deficiência de ferro, especificamente a anemia ferropênica, permanece como uma das deficiências nutricionais mais frequentes e importantes no mundo. Este artigo revisa as principais causas de anemia ferropênica, os atuais métodos de investigação diagnóstica e as estratégias de prevenção. O tratamento com ferro deve ser iniciado sempre por via oral, e a investigação apropriada de sua causa é obrigatória; quando houver falha nesse tratamento por causa de grande perda de sangue, má absorção do ferro ou intolerância a ele, o tratamento por via parenteral deve ser considerado. Os autores discutem os compostos com ferro atualmente disponíveis, o perfil de eficácia, segurança e tolerabilidade desses medicamentos, e o plano terapêutico ideal para o sucesso no tratamento dessa doença tão comum e importante.


Iron deficiency, and especifically iron deficiency anaemia, remains one of the commonest and most important nutritional deficiencies in the world today. This article reviews the main causes of iron deficiency anaemia, the current diagnostic methods and prevention strategies of iron deficiency. The treatment of iron deficiency should always be initiated with oral iron and an investigation of the cause of iron deficiency anaemia is mandatory. When oral iron therapy fails due to high blood losses, iron malabsorption or intolerance to oral iron, parenteral iron administration should be considered. The authors discuss available iron preparations, their efficacy, safety and tolerability, and the optimal therapeutic approach to successfully treat this common and important disease.

ABSTRACT

The peak of the brain edema after intracerebral hemorrhage usually begins after 3 to 4 days.A large quantity of hemoglobin releases and degrades during this process,and its degradation products iron ion,bilirubin and carbon monoxide,etc play important roles in the process of cerebral edema.They all involve in the formation Of delayed brain edema after intracerebral hemorrhage.The research of hemoglobin and its degradation products is expected to find out a new way for the treatment of intracerebral hemorrhage.
