En Cuba se está trabajando desde el año 1987 en el desarrollo de programas de intervención para la prevención de la anemia por deficiencia de hierro en la población, pero a pesar de todo el esfuerzo, no se han obtenido los impactos esperados, y existen diversos factores que pueden estar incidiendo en ello y que pueden sinergizarse. Evidencias científicas nacionales muestran que la baja prevalencia de lactancia materna, el escaso consumo de frutas y vegetales y la deficiencia vitamínica, ejercen influencia en la prevalencia de la anemia en Cuba. El parasitismo intestinal y la infección con H. pylori no están asociados con la prevalencia de anemia en el país. La obesidad e inflamación crónica a bajo tenor requerirían de estudios epidemiológicos que describan las posibles asociaciones entre estos factores.Anemia is a global health problem affecting both developed and developing countries. The causes of anemia may be multifactorial, and several of them are often present at the same time. The main cause of anemia is the low intake of foods with adequate sources of iron both in quantity and quality. Work is being done in Cuba since the year 1987 aimed at developing intervention programs for the prevention of iron deficiency anemia in the population, but despite the great effort, the expected impact has not been achieved, due to the combined influence of various factors. National scientific evidence shows that the low incidence of breastfeeding, the low intake of fruits and vegetables, as well as vitamin deficiency, have an influence on the prevalence of anemia in Cuba. Neither intestinal parasitism nor infection with H

    Full Text Available Se estudiaron 57 lactantes, supuestamente sanos y tomados al azar, de la población urbana entre 6 y 12 meses de edad de un policlínico de la Ciudad de La Habana, con el objetivo de determinar la frecuencia de anemia por deficiencia de hierro y sus factores de riesgo. Se observó anemia por deficiencia de hierro relacionada con la lactancia materna exclusiva de menos de 4 meses de duración, la introducción temprana e ingestión exagerada de leche de vaca y el antecedente de diarreas e ingresos por esta causa. Se halló además correlación directa y significativa del peso al nacer con la ferritina y de la edad gestacional en el momento del parto con la hemoglobina, así como correlación directa de todos los indicadores de la deficiencia de hierro con la duración de la lactancia materna. El rápido crecimiento corporal, la dieta cuyo componente principal fue la leche de vaca y el aumento de las pérdidas por diarreas, constituyen las causas más frecuentes de deficiencia de hierro en este estudio57 infants who were apparently spund were selected at random from the urban population aged 6-12 months of a polyclinic in Havana City aimed at determining the frequency of iron-deficiency anemia and its risk factors. It was observed that iron-deficiency anemia was connected with exclusive breast feeding of less than 4 months of duration, the early introduction and exagerated ingestion of cow milk and the history of diarrheas and admissions for this cause. A direct and significant correlation was found between birth weight and ferritin and between gestational age at delivery and hemoglobin. A direct correlation of all the indicators of iron-deficiency anemia with the duration of breast feeding was also noted. The rapid body growth, the diet with cow milk as the main component and the increase of losses due to diarrheas were the commonest causes of iron-deficiency anemia according to this study

    Full Text Available OBJETIVO: Describir la prevalencia informada de anemia por deficiencia de hierro en mujeres mexicanas en edad reproductiva en los últimos 66 años y analizar la eficacia de las intervenciones informadas para su prevención y manejo. MATERIAL Y MÉTODOS: Revisión de estudios epidemiológicos observacionales, clínicos y programas gubernamentales de intervención, publicados entre 1939 y 2005 con información original. Se consultaron las bases de datos de la Biblioteca Nacional de Medicina de Estados Unidos, Artemisa e índices de revistas mexicanas. La calidad de los ensayos clínicos se evaluó con base en la escala Jadad. Las tendencias de la prevalencia de anemia se analizaron con una regresión lineal ponderada por el tamaño muestral. RESULTADOS: Se incluyeron 46 trabajos de investigación; nueve correspondieron a ensayos clínicos y cuatro a programas operativos; 17 informaron la prevalencia de anemia en no embarazadas y 23 en gestantes. En el primer grupo, la prevalencia ponderada de anemia ha descendido de 39.6 a 15.5%, en tanto que en las gestantes ha disminuido 10 puntos porcentuales, hasta 25%. De los estudios clínicos, 55% se consideraron con un nivel de evidencia adecuado. CONCLUSIONES: La anemia en mujeres en edad reproductiva, y particularmente en las embarazadas, aún constituye un problema de salud pública. De seguir con los esquemas actuales, se requerirían cerca de 57 años para erradicar la anemia entre las no gestantes y 121 para las gestantes. Es necesario evaluar las estrategias de intervención y hacer estudios consistentes que permitan tomar las medidas adecuadas para controlarla.OBJECTIVE: To describe the prevalence of iron deficiency anemia in the past 66 years among Mexican women on reproductive age, and to analyze the efficacy of interventions implemented for its prevention and control.

La anemia se determinó tomando como punto de corte una concentración de hemoglobina <12 g/dL. La deficiencia de hierro se evaluó según la saturación de la transferrina. Además, se evaluó el índice de masa corporal (IMC y los hábitos nutricionales a través de una encuesta. La frecuencia de anemia fue de 15,1% (IC95% 8,7-23,8%, de éste el 33,3% (IC95% 12,8-61,6% correspondió a anemia ferropénica. Se observó asociación entre la presencia de anemia y los niveles disminuidos tanto del hematocrito (<38% como del número de glóbulos rojos (<4,2x 106/uL. Todas las mujeres con anemia ferropénica tenían peso <64 kg e IMC <24,5 kg/m2. Además, se detectó una alta frecuencia de sobrepeso y obesidad (45,4%, alto consumo de grasas, y bajo consumo de legumbres, frutas y verduras. A partir de estos resultados, se sugiere mantener la vigilancia e implementar programas que incluyan a estas mujeres, tanto para evitar deficiencias nutricionales como excesos.

    Full Text Available La deficiencia de hierro es una de las deficiencias de micronutrientes más comunes. Los adolescentes son un grupo vulnerable. Un reconocimiento oportuno puede prevenir una anemia ferropénica, etapa final y grave de dicha deficiencia, insuficientemente conocida en nuestro país. El objetivo de este estudio fue determinar los valores hematológicos en adolescentes y conocer las prevalencias de anemia y deficiencia de hierro. Definidas como a anemia: hematocrito (Hto Iron deficiency is highly frequent among adolescents. Its early detection can prevent the development of a ferropenic anemia, a serious condition. The problem has not been well studied in our country. The purpose of this work was to determine the frequency of iron deficiency and anemia in adolescents. The criteria considered were: hematocrit below 38%, b saturation transferrin below 16%, c ferritin below 15 ng/ml. The study was carried out in 2.265 schoolchildren, 12 years old, of both sexes, in urban and periurban areas in the city of San Salvador de Jujuy (1.250 a.s.l.. The following parameters were measured: hematocrit as well as serum iron and total iron binding capacity, both by colorimetric method. Ferritin was measured by ELISA. Anemia was not found. Iron deficiency as estimated by the iron functional component, was found in 25% of girls and 21% of boys and, through iron stores, in 28% of girls and 18% of boys. Iron deficiency stores in both sexes is the more relevant alteration, indicating that the population sample here studied constitutes a highly vulnerable group. The early detection of iron deficiency will help physical and intellectual development so that adequate sanitary policies are necessary for its prevention.

    El halógeno yodo es un elemento definitivo para el buen funcionamiento de la glándula tiroides y para la formación de las hormonas tiroideas; estas son esenciales para el desarrollo del sistema nervioso central, para el crecimiento, para la termogénesis y para una serie de funciones adicionales sobre el metabolismo como por ejemplo la absorción de la glucosa. Los trastornos por deficiencia de yodo los llamaremos aquí por las siglas DDI, del inglés “Iodine deficiency disorders”.

    Aún en situaciones de marcada yodo-deficiencia, la glándula tiroides es capaz de extraer la máxima cantidad de este elemento de la sangre(hasta 40 veces su concentración, pues está dotada de un mecanismo de transporte activo relacionado con la bomba de sodio, donde la absorción de yodo se logra de una manera parásita al sodio. Se encuentra en forma de yoduros o de yodo elemental y una vez atrapado, este sufre una serie de transformaciones dentro de la glándula conocidas como tiroxinogénesis, con etapas de oxidación, organificación y acoplamiento, lo que da lugar a la formación de las dos hormonas tiroideas, la tiroxina o T4 y la triyodotironina o T3.

    Todos estos procesos se encuentran en buena parte regulados por la hormona tirotropa o TSH, la que también es la responsable de la liberación gradual de las hormonas depositadas en la glándula, la cual se produce a medida que van disminuyendo los niveles de T4 y de T3 en su forma libre, que son las que interactúan con los diversos receptores para ejercer su acción fisiológica(1.

    La carencia de yodo produce una serie de trastornos como la aparición de bocio en los individuos, además de hipotiroidismo; en las embara adas se producen abortos, niños que nacen muertos o que nacen con retardo mental; estos niños cretinos tienen además enanismo y otras alteraciones físicas, lo que los lleva a una baja productividad con una alta demanda de servicios sociales, constituyéndose en

    Full Text Available El presente trabajo tiene por objeto revisar los aspectos teóricos y los estudios realizados en México que sugieren la existencia de la deficiencia moderada de zinc en niños de población rural, así como algunas de las consecuencias de dicha deficiencia en la salud. El zinc es un nutrimento indispensable para el organismo de los humanos y juega un papel importante en una serie de procesos metabólicos: participa en el sitio catalítico de varios sistemas enzimáticos; participa como ion estructural en membranas biológicas, y guarda una estrecha relación con la síntesis de proteínas, entre otras cosas. Es por esto que la deficiencia de zinc está asociada con consecuencias importantes en la salud y la funcionalidad de los individuos, especialmente durante las primeras etapas de la vida. De relevancia para México es la existencia de una deficiencia moderada de zinc en los niños y las consecuencias que ésta pueda tener en la salud de los mismos. Los estudios realizados sugieren que la deficiencia moderada de zinc se presenta asociada con la ingestión de dietas basadas en alimentos de origen vegetal, las cuales contienen cantidades importantes de inhibidores de la absorción de zinc. Este tipo de dietas se consume habitualmente en las zonas rurales y en la población marginal de las ciudades en el país. Entre las consecuencias más importantes de esta deficiencia se encontró un aumento en la presencia de enfermedades infecciosas, especialmente de diarrea, y posibles alteraciones en el desarrollo de la capacidad cognoscitiva.

No es frecuente dentro de la historia natural de la hepatitis A, la aparición de anemia hemolítica, y cuando se presenta, generalmente se asocia a deficiencia de glucosa-6-fosfato deshidrogenasa. Presentamos el caso de un paciente de sexo masculino sin hemólisis previa, con astenia e ictericia de dos meses de evolución y hepatomegalia 14 cm por debajo del reborde costal derecho. Los hallazgos en los exámenes de laboratorios mostraron anemia hemolítica con Coombs directo positivo, anticuerpos tipo inmunoglobulina M contra el virus de la hepatitis A positivos, niveles de bilirrubinas 20 veces y aminotrasferasas cuatro veces por arriba del rango normal; con estos datos el paciente fue diagnosticado como hepatitis A complicada con anemia hemolítica y probable hepatitis autoinmune asociada, por lo que se inició manejo con corticoides, alcanzándose mejoría clínica. Resaltamos la importancia de descartar la infección por el virus de la hepatitis A como posible etiología de anemia hemolítica autoinmune.______________________________________________________________________ Acute auto inmune haemolytic anaemia is associated with a variety of hepatotropic viruses, in particular cytomegalovirus, Epstein Barr virus and hepatitis B.

    Full Text Available La anemia de Fanconi es una patología genética caracterizada por una alteración en la reparación del ADN que se expresa con alteraciones físicas y hematológicas. Es una enfermedad congénita rara y corresponde a la primera causa de anemia aplásica en la infancia. Tiene un curso desfavorable tanto por el deterioro de sus parámetros sanguíneos, así como también por el riesgo aumentado de malignización hematológica. Su único tratamiento curativo es el trasplante de médula ósea. Se presenta el caso de un niño de 3 años, hijo de padres judíos, portador de malformaciones mayores y menores, que presentó un cuadro infeccioso por Mycoplasma pneumoniae que evolucionó a una pancitopenia severa. En el  estudio del caso se buscaron etiologías  que abarcaron desde las infecciosas e inmunológicas hasta  las que involucraban a la medula ósea Una vez que los exámenes realizados descartaron patologías linfoproliferativas, la clínica y la persistencia del cuadro orientaron a buscar alguna condición genética que explicara esta situación.

  7. Necesidades de investigación para el diagnóstico de anemia en poblaciones de altura

    Directory of Open Access Journals (Sweden)

    Gustavo F. Gonzales

    Full Text Available RESUMEN Tanto la deficiencia como la sobrecarga de hierro son situaciones que ponen en riesgo la salud y la vida de las personas, por lo que es importante mantener su homeostasis. Como la hemoglobina contiene 70% del hierro del organismo, la OMS recomienda su medición para determinar la prevalencia de anemia por deficiencia de hierro (ID, a pesar que ellos mismos reconocen que la anemia no es específica de ID. Como la hemoglobina aumenta con la altitud de residencia, la OMS recomienda corregir el punto de corte para definir anemia en la altura. Una objeción a esta corrección es que el aumento de la hemoglobina en la altura no es universal ni aumenta de manera lineal. Además, las poblaciones de mayor antigüedad generacional tienen menos hemoglobina que las más recientes. En infantes, niños, gestantes y adultos, la prevalencia de anemia usando hemoglobina corregida es 3-5 veces mayor que usando marcadores del estatus de hierro. Los programas estatales buscan combatir la anemia mediante la suplementación de hierro; no obstante, resultan ineficaces, especialmente en las poblaciones de altura. Entonces, ¿hay deficiencia de hierro en la altura? Los niveles de hepcidina sérica, hormona que regula la disponibilidad de hierro, son similares a los de nivel del mar indicando que en la altura no hay deficiencia de hierro. Un problema adicional al corregir la hemoglobina por la altura, es que las prevalencias de eritrocitosis disminuyen. En conclusión, la corrección del punto de corte de la hemoglobina en la altura para determinar deficiencia de hierro es inadecuada.

    Full Text Available El propósito de este trabajo es el de presentar un análisis comparativo de los resultados de seis investigaciones en las cuales ha participado el autor sobre la relación entre la deficiencia de hierro y el funcionamiento intelectual. Las investigaciones fueron realizadas en Egipto, Estados Unidos, Guatemala, Indonesia y Tailandia entre niños de edad pre-escolar. La deficiencia de hierro con anemia está entre las dos deficiencias nutricionales más prevalentes en el mundo y es de esperar que su prevalencia sea alta en el Perú, particularmente entre los infantes y niños y entre las madres gestantes y lactantes. Una de las causas importantes es el limitado consumo de alimentos ricos en hierro hemínico que generalmente son muy costosos para los grupos más pobres de la sociedad. El análisis comparativo muestra que los resultados son consistentes a través de los seis estudios y que la deficiencia de hierro con anemia afecta el rendimiento en las pruebas de procesos cognoscitivos específicos y en las pruebas de rendimiento escolar. Los resultados también muestran que dichos efectos son reversibles con el tratamiento apropiado. A su vez, el análisis muestra que no hay evidencia suficiente para inferir que la deficiencia de hierro sin anemia afecta el cociente intelectual.   The purpose of this paper is to present a comparative analysis of the results of six researches in which the author has participated, about the relation between iron deficiency and intellectual performance. The researches were carried out in Egypt, U.S.A., Guatemala, Indonesia and Thailand, with pre-school and school children. Iron deficiency with anemia are among the two nutritional deficiencies of major prevalence in the word and it must be expected that the same goes for Peru. One of the causes of the low consuming of food rich in iron is that these are too expensive for groups of low socioeconomic level. The comparative analysis shows consistent results in the six

    Nelly Zavaleta

    Full Text Available RESUMEN La anemia en niños menores de tres años es un problema de salud pública en el Perú y el mundo. Se estima que la causa principal de la anemia, aunque no la única, es la deficiencia de hierro. Existen muchos estudios y revisiones sobre cómo esta carencia en los infantes impacta negativamente en el desarrollo psicomotor y, a pesar de corregirse la anemia, los niños con este antecedente presentan, a largo plazo, un menor desempeño en las áreas cognitiva, social y emocional. Estos hallazgos se describen en estudios observacionales, de seguimiento, así como en experimentales con grupo control. La anemia puede disminuir el desempeño escolar, y la productividad en la vida adulta, afectando la calidad de vida, y en general la economía de las personas afectadas. Se describen algunos posibles mecanismos de cómo la deficiencia de hierro, con o sin anemia, podría afectar el desarrollo en la infancia; por ello, causa preocupación la alta prevalencia de anemia que se observa en este grupo de edad. La prevención de la anemia en el primer año de vida debe ser la meta para evitar consecuencias en el desarrollo de la persona a largo plazo.

Se evaluó el efecto de la deficiencia de nitrógeno y de fósforo sobre el perfil de APs en inflorescencias de esta maleza. Se realizó un ensayo utilizando un diseño completamente aleatorizado con 10 repeticiones, en el cual las plantas, que crecieron en hidroponia desde mayo hasta octubre, fueron regadas con solución de nutrientes en las que las concentraciones de N o de P reducidas en un 50% respecto del control. La cuantificación de APs en las inflorescencias de S. grisebachii por CG y CG-EM, demuestra un aumento significativo en el contenido total de APs, en los tratamientos con déficit en N o P (1,33 y 1,34 mg g-1 de materia seca, respectivamente, comparados con el control 0,35 mg g-1. Se identificaron siete APs y sus concentraciones variaron entre tratamientos. Senecionina resultó el alcaloide mayoritario en el tratamiento déficit de N, mientras senecifilina resultó más abundante en los tratamientos control y con déficit de P, seguidos en todos los casos por integerrimina y cantidades menores de espartiodina, jacobina, jacozina y retrorsina.Senecio grisebachii Baker is a weed that invades natural pastures and crops in southern Brazil, Uruguay, the mesopotamic provinces and Buenos Aires in Argentina, and is considered to be toxic because of the presence of pyrrolizidine alkaloids (PAs in its tissues.

La anemia se asocia a mayor morbilidad y mortalidad materno-perinatal. En mujeres embarazadas sin anemia, la prevención, mediante el uso de multivitamínicos que contienen hierro en dosis de 30-60 mg de hierro elemental, ha demostrado ser efectiva y se recomienda durante todo el embarazo. En casos de anemia, el diagnóstico de déficit de hierro se establece cuando la ferritina es menor a 30 ug/L y/o la saturación de transferrina es menor a 20%. La severidad de la anemia y la situación temporal en el embarazo, son factores modificantes del tratamiento. En mujeres embarazadas, con hemoglobina ≥9.0 g/dL y que tengan <34 semanas de embarazo, la indicación es tratamiento con hierro oral, en dosis de 100 mg al día, en días alternos, hasta normalizar los parámetros antes mencionados. Si la hemoglobina es <9.0 g/dL, o el embarazo es ≥34 semanas, el uso de hierro intravenoso ha demostrado ser más efectivo en corregir la anemia y el déficit de hierro y en disminuir la morbilidad materno-perinatal. En estos casos, sugerimos el uso del hierro carboximaltosa, dado su perfil de seguridad y efectividad favorable. Recomendamos conocer y practicar estas recomendaciones para el diagnóstico y manejo de la anemia por déficit de hierro durante el embarazo.

    Full Text Available A anemia por deficiência de ferro caracteriza-se como o mais prevalente problema nutricional em todo o mundo. Nesta revisão reuniu-se informações a respeito do metabolismo da hepcidina, avaliando-se seu valor como parâmetro bioquímico na anemia por deficiência de ferro. Realizou-se um levantamento bibliográfico nas bases de dados PUBMED e LILACS, período 2006-2010, referentes à hepcidina como um biomarcador para a regulação do metabolismo do ferro. Foram localizados 35 estudos publicados em revistas internacionais e um estudo sobre o assunto em revista nacional. A produção de hepcidina é regulada homeostaticamente pela anemia e hipóxia. Quando a oferta de oxigênio está inadequada ocorre diminuição do nível de hepcidina. Consequentemente, maior quantidade de ferro proveniente da dieta e dos estoques dos macrófagos e hepatócitos se tornam disponíveis. A hepcidina possui a função de se ligar à ferroportina, regulando a liberação do ferro para o plasma. Quando as concentrações de hepcidina estão baixas, as moléculas de ferroportina são expostas na membrana plasmática e liberam o ferro. Quando os níveis de hepcidina aumentam, a hepcidina liga-se às moléculas de ferroportina induzindo sua internalização e degradação, e o ferro liberado diminui progressivamente. Aparentemente o desenvolvimento do diagnóstico e terapia da anemia baseados no bioindicador hepcidina pode oferecer uma abordagem mais efetiva. Estudos epidemiológicos são necessários para comprovar o valor da hepcidina no diagnóstico diferencial das anemias, incluindo protocolos de amostragem para análise, com padronização similar às utilizadas em outras avaliações bioquímicas, e estabelecimento de pontos de corte para a expressão urinária e plasmática desse peptídeo.Iron deficiency anemia is the most prevalent nutritional problem in the world.

    Full Text Available El sistema NAOPH oxidasa es un complejo enzimático transportador de electrones localizado en la membrana de las células fagocíticas. Oe este sistema hacen parte varias proteínas; un flavocitocromo b558' el cual está conformado por una cadena b (gp91-phox y una cadena a (p22-phox y poral menos 3 proteínas citosólicas (p47-phox, p67- phox, p40-phox. Una alteración gen ética en cualquiera de estas proteínas causa el síndrome de Enfermedad Granulomatosa Crónica (EGC. La caracterizaciÓn de las mutaciones de los pacientes con EGC ha sido fundamental para dilucidar la estructura y función de los componentes del sistema NAOPH oxidasa. En el caso de la p47-phox, se han obtenido hallazgos importantes que la hacen un modelo interesante para estudiar el mecanismo molecular involucrado en regular la expresión y función bioquímica de este sistema. En los pacientes con defecto en la p47-phox investigados hasta ahora, se ha hallado una deleción del dinucleótido GT al comienzo del exón 2 , siendo la mayoría de ellos homocigóticos para esta deleción, la cual posiblemente se debe a eventos de recombinación entre el gen p47 -phox normal y un seudogen recientemente descrito. En el diagnóstico de pacientes no homocigóticos, cualquier mutación encontrada en el análisis del ONA (gONA o cONA puede representar un cambio sufrido por el seudogen. Por lo tanto, para la identificación precisa del defecto gen ético es necesario separar el gen normal del seudogen y analizar las secuencias en forma individual. Los pacientes no homocigóticos posiblemente deben tener una segunda mutación en el alelo tipo silvestre diferente a la deleción GT. De otro lado, a través de mutagénesis sitio-dirigida se pueden modificar algunos de los aminoácidos o dominios de la p47-phox, los cuales pueden ser esenciales para su funcionamiento y su relación con la EGC. Con esta metodología, es posible introducir cambios en un gen cuya secuencia es totalmente

    Full Text Available OBJETIVO: Determinar la prevalencia de ceguera y deficiencia visual en Honduras, sus causas y la respuesta que los servicios de salud están dando a la creciente demanda. MÉTODOS: Estudio poblacional transversal realizado entre junio y diciembre de 2013 mediante la metodología estándar de evaluación rápida de ceguera evitable. Se realizó un muestreo aleatorio en 63 conglomerados de 50 personas de 50 años o más, representativo de todo el país. Se evaluó la agudeza visual (AV mediante una cartilla de Snellen y el estado del cristalino y del polo posterior por oftalmoscopía directa. Se calculó la cobertura de cirugía de catarata y se evaluó su calidad, las causas de tener AV < 20/60 y las barreras para acceder al tratamiento quirúrgico. RESULTADOS: Se examinaron 2 999 personas (95,2% del total previsto. La prevalencia de ceguera fue de 1,9% (intervalo de confianza de 95%: 1,4-2,4% y 82,2% de esos casos era evitable. La catarata no operada fue la causa principal de ceguera (59,2%, seguida del glaucoma (21,1%. Los errores de refracción no corregidos fueron la principal causa de deficiencia visual, tanto severa (19,7% como moderada (58,6%. La cobertura de cirugía de catarata fue de 75,2%. De los ojos operados de catarata, 62,5% alcanzó una AV ≥ 20/60 con la corrección disponible. Las principales barreras para someterse a la cirugía de catarata fueron el costo (27,7% y la falta de disponibilidad o de acceso geográfico al tratamiento (24,6%. CONCLUSIONES: La prevalencia de ceguera y deficiencia visual en Honduras es similar a la de otros países latinoamericanos. Mejorar la capacidad resolutiva de los servicios oftalmológicos, especialmente de cirugía de catarata, desarrollar los servicios ópticos y la atención ocular incorporada en la atención primaria en salud, podrían resolver el 67% de los casos de ceguera.

    Full Text Available El presente trabajo tiene por objeto revisar los aspectos teóricos y los estudios realizados en México que sugieren la existencia de la deficiencia moderada de zinc en niños de población rural, así como algunas de las consecuencias de dicha deficiencia en la salud. El zinc es un nutrimento indispensable para el organismo de los humanos y juega un papel importante en una serie de procesos metabólicos: participa en el sitio catalítico de varios sistemas enzimáticos; participa como ion estructural en membranas biológicas, y guarda una estrecha relación con la síntesis de proteínas, entre otras cosas. Es por esto que la deficiencia de zinc está asociada con consecuencias importantes en la salud y la funcionalidad de los individuos, especialmente durante las primeras etapas de la vida. De relevancia para México es la existencia de una deficiencia moderada de zinc en los niños y las consecuencias que ésta pueda tener en la salud de los mismos. Los estudios realizados sugieren que la deficiencia moderada de zinc se presenta asociada con la ingestión de dietas basadas en alimentos de origen vegetal, las cuales contienen cantidades importantes de inhibidores de la absorción de zinc. Este tipo de dietas se consume habitualmente en las zonas rurales y en la población marginal de las ciudades en el país. Entre las consecuencias más importantes de esta deficiencia se encontró un aumento en la presencia de enfermedades infecciosas, especialmente de diarrea, y posibles alteraciones en el desarrollo de la capacidad cognoscitiva.The purpose of this article is to review theoretical aspects and research performed in Mexico suggesting the existence of marginal zinc deficiency in rural children and its consequences on health. Zinc is an indispensable nutrient for humans since it plays an important role in several metabolic pathways: it participates in the catalytic site of several enzymes, as a structural ion of biological membranes and is

    Para confirmar el efecto que tienen las deficiencias de nutrientes minerales mayores en la asignación de la materia seca en órganos vegetativos de Passiflora mollissima, se realizó un experimento en condiciones de vivero, mediante la técnica de deficiencia inducida por elemento faltante. Se pudo establecer que las deficiencias de N y K reducen en alta proporción el área foliar y la masa de la planta, mientras que las deficiencias de P afectan el patrón de distribución de la biomasa, al favorecer la mayor acumulación en la raíz. En general, las deficiencias de macronutrientes afectan de forma drástica la distribución de la materia seca en los órganos vegetativos de la planta y producen síntomas específicos que pueden servir como indicadores del estado nutricional en condiciones de campo.

    Full Text Available Los Desórdenes por Deficiencia de Yodo (DDY son uno de los mayores problemas en salud pública en el mundo actual, en especial en niños y embarazadas. Estos trastornos truncan el desarrollo socioeconómico en aquellas zonas que los padecen; las poblaciones que viven en zonas yodo-deficientes siempre van a estar expuestas a sufrir las consecuencias originadas por esta deficiencia, en especial el aumento en la mortalidad perinatal, retardo mental, alteraciones en la síntesis de hormonas tiroideas, hipotiroidismo, hipertiroidismo y bocio. La mejor forma de evaluar los DDY es por medio de la yoduria y la mejor estrategia para reducir la prevalencia de estos desórdenes en la población es a través de la yodación universal de la sal. Para actualizar el conocimiento de esta problemática –tanto en el mundo como en Colombia- se realizó una revisión sistemática de la literatura médica expuesta en las bases de datos de MEDLINE y de LILACS. En total, la búsqueda arrojó la presencia de 723 artículos, la revisión de sus resúmenes permitió escoger inicialmente 114 artículos, de los cuales se decidió incluir en la revisión a 60 de ellos. Se encontró que en Colombia el diagnóstico de DDI es subvalorado, desconociéndose la problemática actual y el estado del yodo poblacional, por lo que es necesario realizar estos estudios, ya que es evidente el abandono político de este problema prevenible, predecible y tratable.

    El desconocimiento de los signos y síntomas visibles de las deficiencias nutricionales no permite establecer oportunos correctivos para manejar plantas con suficiente vigor, producción y calidad de los frutos. Plantas de uchuva ecotipo Colombia, propagadas por semilla, se sembraron en sustrato de arena cuarcítica en materas de plástico (25 L, y se mantuvieron durante 135 días en condiciones de invernadero de plástico en Bogotá. Las deficiencias nutricionales se indujeron a través de soluciones nutritivas, usando el método del elemento faltante y empleando un diseño completamente al azar con ocho tratamientos y cinco repeticiones, a saber: T0. testigo con fertilización completa; T1. fertilización completa –N; T2. –P; T3. –K; T4. –Ca; T5. –Mg; T6. –B, y T7. agua potable únicamente. Solamente en el caso del nitrógeno se aplicó 15% del N de la fertilización completa. Quincenalmente se efectuó una descripción visual y se llevó un registro fotográfico de los síntomas manifestados. Las plantas con deficiencias de N, K y B presentaron los síntomas más severos, generando efectos negativos sobre la arquitectura y el deficiente porte de las plantas, además de causar una seria afección sobre el tejido vegetal. Las plantas deficientes en B tomaron una forma de roseta, típico síntoma hipoplástico. Las uchuvas que sufrieron deficiencias de P, Ca, Mg presentaron distorsiones en el color del follaje, observándose para la deficiencia de P, una coloración púrpura tanto en hojas de la zona reproductiva de la planta como en las del tallo principal. Las deficiencias de Mg y Ca, respectivamente, indujeron clorosis foliar intervenal y coloraciones anaranjadas.

    Full Text Available OBJETIVO: Avaliar fatores determinantes de anemia e deficiência de ferro em crianças de duas creches da cidade de Pontal, sudeste do Brasil. MÉTODOS: Estudo transversal foi realizado avaliando-se 192 crianças com idades entre 12 e 72 meses. Dados pessoais (idade, sexo, uso de ferro medicamentoso, duração do aleitamento materno, tipo de parto, cuidados pré-natais, peso e estatura e dados socioeconômicos (número de co-habitantes, escolaridade dos pais e renda per capita familiar foram obtidos e correlacionados com hemoglobina, receptores de transferrina, ferritina e anemia ferropriva. RESULTADOS: A idade foi a variável mais afetada pelo estado nutricional de ferro, correlacionando-se com maiores valores de hemoglobina e ferritina e menores valores de receptor de transferrina, sendo que menos anemia ferropriva foi detectada quanto maior a idade. As outras variáveis estudadas não apresentaram correlação com o estado nutricional de ferro. CONCLUSÃO: Os dados sugerem que as estratégias de controle para essa população de crianças pré-escolares devem ser direcionadas especialmente para aquelas de menor idade.OBJECTIVE: To examine the determining factors of anemia and iron deficiency in children attending two day care centers in the town of Pontal, southeast of Brazil.

    Full Text Available Las encuestas demográficas de salud y población del Perú indican que las tasas globales de fecundidad, la proporción de adolescentes embarazadas y la mortalidad maternoinfantil son más altas en la selva que en otras zonas del país. Las parasitosis intestinales endémicas agravan el riesgo de anemia ya generalmente presente en las embarazadas por deficiencias de hierro, ácido fólico y otros nutrientes. En muchos países latinoamericanos, esa es la complicación más frecuente del embarazo y está asociada con partos pretérmino, bajo peso al nacer y mortalidad perinatal. Los estudios realizados sobre este tema en la selva peruana son escasos y no se dispone de estimaciones confiables de la prevalencia de anemia durante la gestación. Los autores se propusieron determinar la prevalencia de anemia en mujeres gestantes que acudían al Hospital Regional de Pucallpa, en la selva del Perú, entre enero de 1993 y junio de 1995. El estudio de corte transversal se basó en los registros de control prenatal y de parto de 1 015 embarazadas y permitió estudiar la asociación entre la prevalencia de anemia y variables como edad cronológica, escolaridad, número de gestaciones previas y peso de la madre al inicio del embarazo. También se compararon los valores de la hemoglobina materna con el peso de los recién nacidos. La prevalencia de anemia en la población de gestantes fue de 70,1%, valor que no se modificó por efecto de la edad materna, la escolaridad ni el intervalo intergenésico. La prevalencia de anemia se asoció directamente con el número de gestaciones e inversamente con la ganancia de peso durante el embarazo. La tasa de mortalidad perinatal fue de 37,7 por 1 000 nacidos. Ni esta tasa ni el peso de los recién nacidos resultaron asociados con el grado de anemia de la madre. El análisis de regresión multivariado muestra que el peso de la madre al inicio de la gestación (P = 0,0001, el peso ganado durante la gestación (P = 0

MÉTODOS: Estudio poblacional transversal mediante la metodología estándar de evaluación rápida de ceguera evitable. Se seleccionaron 50 personas de 50 años o más de cada uno de 84 conglomerados escogidos mediante muestreo aleatorio representativo de todo el país. Se evaluó la agudeza visual (AV mediante una cartilla de Snellen y el estado del cristalino y del polo posterior por oftalmoscopía directa. Se calculó la cobertura de cirugía de catarata y se evaluó su calidad, así como las causas de tener AV < 20/60 y las barreras para acceder al tratamiento quirúrgico. RESULTADOS: Se examinaron 4 125 personas (98,2% de la muestra calculada. La prevalencia de ceguera ajustada por la edad y el sexo fue de 3,0% (intervalo de confianza de 95%: 2,3-3,6. La principal causa de ceguera fue la catarata (66,4%, seguida del glaucoma (10,2%. La catarata (69,2% fue la principal causa de deficiencia visual (DV severa y los errores de refracción no corregidos fueron la principal causa de DV moderada (60,7%. La cobertura quirúrgica de catarata en personas fue de 76,3%. De todos los ojos operados de catarata, 58,0% logró una AV < 20/60 con la corrección disponible. CONCLUSIONES: La prevalencia de ceguera en Panamá se ubica en un nivel medio con respecto a la encontrada en otros países de la Región. Es posible disminuir este problema, ya que 76,2% de los casos de ceguera y 85,0% de los casos de DV severa corresponden a causas evitables.

    Full Text Available Cold agglutinin disease (CAD with autoimmune haemolytic anemia is characterized by the production of harmful cold autoantibodies associated with increased red cell destruction during exposure to cold. The treatment of CAD is very difficult and a great effort is required to obtain therapeutic success. Cyclophosphamide is a potent immunosuppressive agent which is widely used in all bone marrow transplantation conditioning regimens for patients with acquired severe aplastic anemia. In this report, we describe the case of a coronary artery disease patient with severe CAD, but without lymphoproliferative disease, in which general measures and immunosuppressive therapies were adopted, there by avoiding blood transfusions.A doença por aglutininas a frio (CAD cursando com anemia hemolítica auto-imune (AHAI é decorrente da produção de autoanticorpos que reagem muito bem a baixas temperaturas, dirigidos contra hemácias autólogas. A habilidade desses anticorpos em destruir as hemácias encontra-se diretamente relacionada à sua capacidade em fixar complemento durante a exposição do paciente a baixas temperaturas. A AHAI por anticorpos frios pode ser idiopática - ausência de doença de base - ou secundária, geralmente associada a desordens linfoproliferativas de células B ou determinados processos infecciosos. A hemólise é intravascular, através de aglutininas da classe IgM, com teste direto da antiglobulina humana positivo para complemento. O tratamento da CAD é difícil, exigindo um esforço contínuo, necessário para se obter sucesso terapêutico. A ciclofosfamida é um agente imunossupressor potente, amplamente utilizado em transplantes de medula óssea, particularmente nos portadores de anemia aplástica. Descrevemos o caso de um coronariopata portador de CAD severa, cuja exploração diagnóstica excluiu doença linfoproliferativa. Adotamos medidas gerais de suporte e terapia imunossupressora, coibindo o uso de hemotransfusões.

    Full Text Available

    Con motivo de la llamada “Reunión de Quito”, organizada para valorar los avances de los Programas de Control del Bocio y Cretinismo Endémicos ejecutados en los diferentes países latinoamericanos, recibimos el libro del Profesor Hetzel en el cual el autor acuña la frase “SOS para un Billón”; allí hace un llamado a la conciencia internacional sobre el riesgo que tienen un billón de personas en el mundo de padecer deficiencia de yodo, a pesar de todas las medidas que se han hecho para solventar este problema (1.

    Este aspecto llama la atención al considerar que la deficiencia de yodo en las comunidades mundiales, aun se halla en vigencia; lo más alarmante es que si bien es verdad en muchos países se ha logrado el acceso a fuentes de yodo por yodación de la sal u otros vehículos, aun existenÊ áreas en el mundo en las cuales la población no tiene esta oportunidad. Aparte de esto las consecuencias de la carencia de yodo, particularmente la deficiencia mental y el retraso del crecimiento y desarrollo, hacen de este panorama un escenario sombrío para millones de niños en el ámbito universal.

    América Latina no escapa a esta realidad, pues la carencia de yodo en su población ha tenido resultados biológicos y sociales de enorme impacto, características propias de los países de poco desarrollo económico y con sistemas frágiles que lo alimentan.

    Esta patología tan frecuente en América y en particular en las zonas del altiplano andino, ha sido objeto de innumerables estudios y publicaciones que han tratado de hacer una retrospectiva epidemiológica que explique las raíces y orígenes de este llamado “mal andino” y que tanto daño ha hecho a todas las comunidades de Latinoamérica.

    Se tiene conocimiento de un documento chino que data de cerca de 3000 años A.C. que contiene, posiblemente la primera descripción de la presencia del bocio. Así mismo el papiro de Ebers del antiguo Egipto

    Full Text Available Objective: To describe the occurrence of hospitalizations for iron deficiency anemia in Brazil between 2005 and 2014 by sex and age group. Methods: Observational epidemiological study, descriptive, retrospective with the qualitative and quantitative approach. The admission data were analyzed by place of detention for iron deficiency anemia in the regions of Brazil between 2005 and 2014 according to age group (0-19 years and sex, collected by the Department of Unified Health System through ICD-10 morbidity list. Results: The females had higher prevalence of hospitalizations with 52.03% of cases, however the male had the result of 47.97% incidence. The age group 15-19 was the most prevalent in women in all regions of Brazil. For men, the male children of hospitalizations of 1-4 years were the most frequent in all regions. Conclusion: The aged 15-19 years was the one with the highest number of hospitalizations among women, which may be explained by factors such as cycle menstrual, hormonal and behavioral changes related to the normal adolescence syndrome, beyond the Western lifestyle, that favors foods considered junk food. The age range of 1-4 years was the most prevalent in males. This can be explained by the increased need of mineral iron, for growth and development during the first 2 years of the child, the more accelerated in children.

    Full Text Available OBJETIVOS: Estimar los costos directos e indirectos de la deficiencia de hierro (DH y la anemia ferropénica (AF en Argentina y compararlos con los costos de un programa específico para su prevención y tratamiento. MÉTODOS: Análisis de escenario previo (ex ante de la relación costo-beneficio de un programa de prevención y tratamiento de la AF dirigido a todos los niños y las embarazadas pobres y sin cobertura social de Argentina. Las consecuencias económicas de la DH y la AF se estimaron a partir de los costos directos - gastos vinculados a la atención de un parto prematuro - e indirectos - pérdidas en la productividad futura de los niños por su peor desarrollo cognitivo debido a la DH y la menor productividad de los adultos por la AF - mediante la metodología específica desarrollada por The Micronutrient Initiative. Las intervenciones se definieron según las Guías de Práctica Clínica vigentes en Argentina y los costos de los componentes se tomaron de los precios de las licitaciones del Ministerio de Salud de la Nación. RESULTADOS: Cada US$ 1,00 invertido en un programa de prevención y tratamiento de la DH y la AF, con una cobertura de 90% de la población de lactantes y embarazadas pobres sin seguro explícito de salud, representaría un ahorro de US$ 33,40 por la prevención de las pérdidas económicas debidas a estas enfermedades. CONCLUSIÓN: Las intervenciones para enfrentar la DH no solo mejoran significativamente el estado de salud de la población, sino que representan un ahorro considerable de recursos.OBJECTIVES: To estimate the direct and indirect cost of iron deficiency (ID and iron-deficiency anemia (IDA in Argentina and compare it with the cost of a prevention and treatment program.

  2. Fanconi anemia.

    Science.gov (United States)

    Soulier, Jean

    2011-01-01

    Fanconi anemia (FA) is the most frequent inherited cause of BM failure (BMF). Fifteen FANC genes have been identified to date, the most prevalent being FANCA, FANCC, FANCG, and FANCD2. In addition to classical presentations with progressive BMF during childhood and a positive chromosome breakage test in the blood, atypical clinical and/or biological situations can be seen in which a FA diagnosis has to be confirmed or eliminated. For this, a range of biological tools have been developed, including analysis of skin fibroblasts. FA patients experience a strong selective pressure in the BM that predisposes to clonal evolution and to the emergence in their teens or young adulthood of myelodysplasia syndrome (MDS) and/or acute myeloid leukemia (AML) with a specific pattern of somatic chromosomal lesions. The cellular mechanisms underlying (1) the hematopoietic defect which leads to progressive BMF and (2) somatic clonal evolutions in this background, are still largely elusive. Elucidation of these mechanisms at the molecular and cellular levels should be useful to understand the physiopathology of the disease and to adapt the follow-up and treatment of FA patients. This may also ultimately benefit older, non-FA patients with aplastic anemia, MDS/AML for whom FA represents a model genetic condition.

    1981-06-01

    hereditary anemias of mice have been the chief objects of investigation. At present under study are four macrocytic anemias, five hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an α-thalassemia, and a new target-cell anemia. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse. Each anemia is studied through: (a) characterization of peripheral blood values, (b) determinations of radiosensitivity under a variety of conditions, (c) measurements of iron metabolism and heme synthesis, (d) histological and biochemical study of blood-forming tissue, (e) functional tests of the stem cell component, (f) examination of responses to erythroid stimuli, and (g) transplantation of tissue between individuals of differently affected genotypes

Incluyeron allí casos de excesiva destrucción de sangre asociada a diversas infecciones ó intoxicaciones lo mismo que casos de etiología desconocida. Chauffard fue capaz de demostrar autohemolisinas en el suero de unos pocos casos de anemia hemolítica aguda adquirida y se refirió a ellos como "ictericias hemolisínicas". Sin embargo por muchos años existió la duda de que hubiera un verdadero tipo de anemia hemolítica adquirida y muy poco fue tenida en cuenta la posibilidad de que pudiera jugar papel en estos casos una reacción inmunológica.

The aim of this paper is to study further the relationship between ocular and renal lesions and biochemical alterations in rats fed a choline-deficient diet. Fifty one weanling male Wistar rats, were divided into two groups. Thirty one of them were fed a choline-deficient diet and the rest was fed a choline-supplemented diet ad libitum. Animals from both groups were killed between the fifth and the eighth day. Urea, creatinine and homocysteine concentrations in blood were determined. Eyes were used for light microscopy study; high resolution light microscopy and the study of the retina as "rétine a plat". Kidneys were studied by light microscopy. Choline-supplemented rats did not show ocular or renal lesion. Choline-deficient rats that showed renal lesions, tubular or cortical necrosis, did not always have ocular changes. There were no ocular changes in the only choline-deficient rat without renal lesion. The ocular changes consisted mainly in haemorrhage in both cameras and ciliary and vitreous bodies.

    2015-12-01

    Full Text Available Resumen Introducción: la deficiencia de antitrombina III hereditaria es una rara enfermedad que afecta al 0.02-0.2% de la población. Puede presentar mayor frecuencia de complicaciones y resultados adversos tanto en la madre como en el feto. Se presenta el manejo obstétrico de dos gestaciones consecutivas en una mujer con deficiencia de antitrombina III. Descripción: en ambos embarazos la madre realiza profilaxis de la enfermedad tromboembólica con heparina de bajo peso molecular para evitar la aparición de esta patología tanto en el embarazo como en el puerperio y mejorar el flujo útero-placen-tario. Con respecto a las complicaciones obstétricas, sólo existe un enlentecimiento del crecimiento fetal que obliga a un control obstétrico estricto. En ambas gestaciones los estudios eco-Doppler están dentro de la normalidad lo que permite una conducta expectante, consiguiendo llegar a término. Discusión: la profilaxis con heparina de bajo peso molecular en las gestantes con esta trombofilia y las intervenciones preventivas de factores de riesgo de enfermedad tromboembólica, junto con un control obstétrico adecuado, ha conseguido evitar la apari-ción de complicaciones derivadas de esta patología en el embarazo y en el puerperio. Por otra parte, el control del crecimiento fetal y el estudio Eco-Doppler han permitido asegurar el bienestar fetal no adelan-tando el parto, consiguiendo partos a término.

    Full Text Available El sentido de la visión constituye la fuente principal de adquisición de información del individuo, de aquí la importancia de un buen diagnóstico y corrección, en su caso, de cualquier anomalía en la misma para un correcto aprendizaje, especialmente en los primeros años de escolarización. En este artículo se exponen los resultados de una encuesta pasada a maestros de centros educativos andaluces mediante la que se pretende poner de manifiesto sus conocimientos sobre las deficiencias visuales que pueden presentar sus alumnos, y la incidencia que podrían tener sobre su rendimiento escolar. Los resultados indican que dicho conocimiento se suele circunscribir a las anomalías de tipo refractivo, considerando que se hallan bien tratadas en sus alumnos. A pesar de la importancia que atribuyen a estas deficiencias sobre el aprendizaje escolar, piensan que otros factores pueden poseer un papel más relevante. Asimismo se consideran partidarios de recibir una formación más completa al respecto.

    Full Text Available RESUMEN: El propósito de este estudio ha sido identificar posibles subtipos de alumnos con Deficiencia Mental basados en funciones motrices gmesas. Se seleccionó un grupo de alumnos, de un centro específico de Deficiencia Mental, que no presentaron deficiencias motóricas asociadas y se les administraron los subtests de motricidad gruesa del «Test Bruininks-Ozeretsky para medir la eficacia motriz». Los cuatro subtipos resultantes mostraron diferentes perfiles de desarrollo motor. A partir de estos resultados, se recomienda diseñar programas específicos que intenten paliar los trastornos motrices gruesos, analizados para cada uno de los subtipos hallados, y realizar adaptaciones curriculares pertinentes, teniendo en cuenta los perfiles motrices estudiados.ABSTRACT: The goal of this work was to identify some different cathegories of mental retarded people, depending on their gross motor functioning. A group of mental retarded people was selected from a special education school. None of theese students presented any associated motor deficiency. The gross motor subtests from the Bruininks-Ozeretsky test were administered in order to evaluate the motor eficiency of these mental retarded people. The resulting four cathegories showed different motor development profiles. From theese results it's recommended to design curricula-based intended to amiliorate the specific gross motor deficits of each group and making didactical schedules taking into account the motor profiles studied.RESUME: Le propos de cette étude est identifier possibles subtypes d'élèves avec déficience mental basses en fonctions motrices grosses.

Las deficiencias de hierro y acido fólico son la causa de graves problemas de salud en la mujer gestante y en el niño, con implicaciones negativas para el desarrollo económico y social de los países. Objetivos. Evaluar los cambios de conocimientos sobre funciones, alimentos fuentes y biodisponibilidad del hierro y folatos, el consumo y la tolerancia de un suplemento y el comportamiento de los índices globulares en gestantes del programa prenatal de la Empresa Social del Estado Hospital Gilberto Mejía Mejía de Rionegro, Antioquia, Colombia, entre abril de 2002 y abril de 2003. Materiales y métodos. Estudio cuasi experimental en una muestra de 42 madres, seleccionada por conveniencia, con una confianza del 95%. La intervención fue un programa de educación nutricional y el suministro de un suplemento con 60 mg de hierro elemental, 400 J.g de acido fólico y 70 mg de vitamina C, elaborado para la investigación por el Laboratorio Profesional Farmacéutico, LAPROFF. El efecto de la intervención se midió en los cambios de conocimientos relacionados con las practicas que modifican la biodisponibilidad y el consumo de alimentos fuentes de estos nutrientes, en la tolerancia y la adherencia al suplemento y en la modificación de variables hematológicas: hemoglobina, hematocrito y ferritina. Resultados. Hubo cambios positivos de conocimientos sobre cómo mejorar las practicas alimentarias y la ingestión del suplemento; el 94,4% de las participantes no presentó anemia al finalizar la gestación. Conclusión. Estos resultados concuerdan con otros provenientes de poblaciones similares; se justifica implementar esta estrategia integrada en los programas de control prenatal de Colombia.

    2009-01-01

    Fanconi anemia is a rare inherited disease characterized by congenital anomalies, growth retardation, aplastic anemia and an increased risk of acute myeloid leukemia and squamous cell carcinomas. The disease is caused by mutation in genes encoding proteins required for the Fanconi anemia pathway, a response mechanism to replicative stress, including that caused by genotoxins that cause DNA interstrand crosslinks. Defects in the Fanconi anemia pathway lead to genomic instability and apoptosis of proliferating cells. To date, 13 complementation groups of Fanconi anemia were identified. Five of these genes have been deleted or mutated in the mouse, as well as a sixth key regulatory gene, to create mouse models of Fanconi anemia. This review summarizes the phenotype of each of the Fanconi anemia mouse models and highlights how genetic and interventional studies using the strains have yielded novel insight into therapeutic strategies for Fanconi anemia and into how the Fanconi anemia pathway protects against genomic instability.

    Full Text Available Introducción. La disminución de los depósitos de hierro constituye el primer eslabón de la cadena conducente a la deficiencia de hierro, la carencia nutricional más prevalente y principal causa de anemia en todo el mundo, situación que puede prevenirse mediante la fortificación de alimentos. Objetivo. Comparar la eficacia del hierro aminoquelado con el sulfato ferroso como fortificante de un complemento alimentario en preescolares con deficiencia de hierro. Materiales y métodos. Se llevó a cabo un ensayo clínico triple ciego con distribución aleatoria de grupos. Se analizaron 56 preescolares con deficiencia de hierro (ferritina menor de 24 ng/ml a los que se les dio diariamente 13 g de leche con 12,5 mg de hierro. Después de dos meses se midieron los niveles de hemoglobina, hematocrito y ferritina sérica. Resultados. En el grupo con sulfato ferroso la concentración de ferritina sérica aumentó de 18,8 a 24,1ng/ml, mientras que dicha variación fue de 18,4 a 29,7 ng/ml con el hierro aminoquelado, en ambos casos con diferencias significativas. El nivel de ferritina final difirió según el grupo de estudio, siendo mayor en el grupo con hierro aminoquelado (p=0,022. La hemoglobina y el hematocrito no variaron después de la intervención. Las reacciones adversas en el grupo con sulfato ferroso fueron de 35,7 %, en contraste con el 42,9 % en el grupo con hierro aminoquelado; cinco niños presentaron infección delas vías respiratorias, sin diferencias estadísticas. Conclusiones. Los dos compuestos aumentan los niveles de ferritina, siendo mayor el aumento entre quienes toman leche con hierro aminoquelado. No fue diferente la incidencia de reacciones adversas o de infecciones entre los grupos. Identificador en Clinicaltrials.gov: NCT01412723 doi: http://dx.doi.org/10.7705/biomedica.v33i3.775

    Anemia is the most common hematological abnormality in cancer patients is often under-recognized and undertreated. The pathogenesis of cancer anemia is complex and most of time multifactorial; involving factors related to the tumor itself or its therapy. While anemia can be present in a wide range of symptoms, involing almost every organ, it is beleived that it contributes much to cancer-related-fatigue, one of the most common symptoms in cancer patients. In addition there is increasing evidence to suggest that anemia is an independent factor adversely affecting tumor reponse and patient survival. While blood transfusion was the only option to treat cancer related anemia, the use of recombinant human erythropoietin (rHuEPO) is becomig the new standard of care, more so with the recent studies demonstrating the feasibility of a sigle weekly injection .Things are even getting better with the recent approval of a new form of rHuEPO; Darbepoetin an analogue with a 3-fold longer half-life. In addition to its effects in raising homoglobin, several well controlled studies demonstrated decrease in transfusion requirementsand better qualify of life assessed objectively using standard assesments scales.

    2009-04-01

    Equine Infectious Anemia (EIA) is a reportable, eradicable epizootic disease caused by the equine lentivirus of the retrovirus family which affects equids only and occurs worldwide. The virus is transmitted by blood, mainly by sanguivorous insects. The main symptoms of the disease are pyrexia, apathy, loss of body condition and weight, anemia, edema and petechia. However, infected horses can also be inapparent carriers without any overt signs. The disease is diagnosed by serological tests like the Coggins test and ELISA tests. Presently, Switzerland is offi cially free from EIA. However, Switzerland is permanently at risk of introducing the virus as cases of EIA have recently been reported in different European countries.

    Full Text Available A anemia aplástica é distúrbio caracterizado por pancitopenia e medula óssea hipocelular, com substituição gordurosa dos elementos e sem nenhum sinal de transformação maligna ou doença mieloproliferativa. Acomete geralmente adultos jovens e idosos, sem preferência sexual. A maioria dos casos é adquirida, mas pode ocorrer hereditariamente, por distúrbio molecular (anemia de Fanconi. A associação com gravidez é rara, estando relacionada com alta morbidade e mortalidade materna e fetal. Os autores descrevem o caso de uma paciente com anemia aplástica, diagnosticada previamente, cuja gestação complicou com infecção do trato urinário, doença hipertensiva específica da gestação e restrição de crescimento fetal, com parto prematuro eletivo. Apesar das condições adversas na gravidez e parto, mãe e recém-nascido tiveram evolução clínica satisfatória.Aplastic anemia is characterized by a circulating pancytopenia, hypocellularity, and fatty replacement of cellular marrow elements, without evidence of malignant transformation or myeloproliferative disease. It usually affects young and senior adults, without any sexual preference. Most cases of aplastic anemia are acquired, but the disease may also be inherited due to a molecular disorder (Fanconi's anemia. Aplastic anemia in pregnancy is an extremely rare condition with high maternal and fetal morbidity and mortality rates. The authors describe a case of a patient with previously diagnosed aplastic anemia, whose pregnancy was complicated with urinary tract infection, preeclampsia and fetal growth restriction, with elective preterm birth. In spite of the adverse conditions in pregnancy and delivery, mother and newborn had a satisfactory clinical evolution.

    Full Text Available Introduction: We present the case of a 65 years- old woman who was admitted with a severe macrocytic anemia Hb= 5.7g/dl and diffuse bone pain. Biologically she has moderate thrombocytopenia 35 000/µl, a hepatic cytolysis and cholestatic syndrome. Material and method: The patient was extensively evaluated before presentation for a mild iron - deficiency anemia for which she underwent endoscopic examination of the upper and lower gastrointestinal tract- normal. The bone marrow aspiration on admission revealed a marked hyperplasia of the erythroblastic line with ~50% basophilic erythroblasts suggesting a regenerative erythroid hyperplasia. These changes along with the marked reticulocytosis on the peripheral blood smear oriented us towards a hemolytic anemia; Folic acid, vitamin B12, autoimmune tests and hemolytic tests were all normal. We continued the investigations with a thoraco-abdominopelvic computed tomography which identified diffuse demineralization, vertebral compactation and pelvic stress fractures. The breast examination revealed a right breast nodule, but the breast ultrasonography pleaded for benignity. Lacking a clear definitive diagnosis we decided to perform a bone marrow biopsy. Results: The osteo- medullary biopsy pointed towards a medullar invasion from a lobular mammary carcinoma; In these circumstances we performed an ultrasound guided biopsy of the right mammary lump thus histologically confirming a tumoral invasion of the bone marrow with subsequent anemia. The patient started chemotherapy in the Oncology ward. Conclusion: The particularity of this case consists in the pattern of anemia, which initially seemed iron deficient and afterwards macrocytic – apparently hemolytic and was actually due to the tumoral medullar invasion and also the nonspecific ultrasonographic appearance of the breast tumor.

    Anaemia is a problem that affects almost 10% over 65 years and 20% over 85 years. There is no physiological anaemia in the elderly. Any anaemia expresses the existence of a pathological process, regardless of its severity. Anaemia in the elderly is always associated with a poor prognosis that is in terms of mortality, morbidity and risk of fragility. The diagnostic approach to anemia in the elderly is the same as in younger individual. There are many causes of anaemia; anaemia balance is a complex diagnostic process. Most anaemias are due to a deficiency, chronic inflammation or comorbidity. However, in the elderly, the etiology of anaemia is often multifactorial. In a number of cases remain unexplained anaemia. In a number of cases, anemia remain unexplained. Treatment of anaemia is the treatment of the cause, but specific therapeutic aspects to the elderly should be considered, as among other martial substitution or use of erythropoietin (EPO).

MÉTODOS: Se realizó un estudio de prevalencia en 242 personas con malaria por P. falciparum que consultaron al Programa de Enfermedades Tropicales en la ciudad de Buenaventura, Colombia. Se midieron los niveles de parasitemia y se determinó la presencia de defectos eritrocíticos congénitos (deficiencia de glucosa-6-fosfato deshidrogenasa [G6PD] y presencia de hemoglobinas anormales y de talasemias y de otros factores potencialmente relacionados con los niveles de parasitemia. RESULTADOS: La prevalencia obtenida de defectos eritrocíticos fue de 26,4% (IC95% 21,0 a 32,5, similar a la hallada en estudios realizados antes en la misma zona. En los modelos de regresión múltiple, las personas con drepanocitosis o deficiencia total de la G6PD presentaron una menor densidad de parasitemia que las personas sin defecto, y el riesgo de parasitemias altas fue menor en estas personas después de ajustes respecto a otras variables de interés (razón de posibilidades [odds ratio, RP]: 0,30 y 0,72, respectivamente. CONCLUSIONES: Los resultados confirman una alta prevalencia de defectos eritrocíticos en el Pacífico colombiano, en una población con características étnicas similares a las de algunas poblaciones del África Occidental, y aportan información en favor de la existencia de resistencia innata a la malaria en personas portadoras de hemoglobina AS o con deficiencia de la G6PD.OBJECTIVES: To determine the prevalence of some erythrocyte defects and to evaluate the relation that that has with parasitemia density in individuals diagnosed with Plasmodium falciparum malaria in a population in the Pacific coastal region of Colombia.

    The development of recombinant human erythropoietin and its introduction into the market in the late 1980s has significantly improved the quality of life of patients with chronic kidney disease (CKD) and reduced the need for blood transfusions. Starting from a cautious target, a progressive increase in the recommended hemoglobin levels has been observed over the years, in parallel with an increase in the obtained levels. This trend has gone together with the publication of findings of observational studies showing a relationship between the increase in hemoglobin levels and a reduction in the mortality risk, with the conduction of clinical trials testing the effects of complete anemia correction, and with the compilation of guidelines on anemia control in CKD patients by scientific societies and organizations. In the last two years, evidence of a possible increase in the mortality risk in those patients who were randomized to high hemoglobin levels has resulted in a decrease in the upper limit of the recommended Hb target to be obtained with erythropoietin stimulating agents (ESA), and consequently in a narrowing of the target range. Comparison of guidelines on anemia control in CKD patients is an interesting starting point to discuss single recommendations, strengthen their importance, or suggest new topics of research to fill up important gaps in knowledge.

    2017-11-01

    Full Text Available In order to evaluate C-reactive protein, rate of globular sedimentation, reticulocytes and erythrocyte distribution width, in infants with iron deficiency anemia, 114 children of both genders were studied, aged 0 to 5 years, who attended the pediatric consultation of three health centers in the city of Cumana, Sucre state. The infants were divided into three groups: 35 apparently healthy children formed the control group, 59 children enrolled in iron deficiency anemia and 20 children with anemia from other causes. Each infant was determined the levels of serum iron, ferritin, C-reactive protein (CRP, hemoglobin, hematocrit, hematimetric indices (MCHC and MCV, red cell distribution width (ADE, erythrocyte sedimentation rate (ESR and percentage reticulocyte. An ANOVA statistical analysis was applied to determine possible differences between the evaluated parameters. There were highly significant differences in the levels of iron, hemoglobin, hematocrit, MCHC, MCV and ADE among the three groups studied; while ferritin variables, reticulocytes, CRP and ESR showed no significant differences among these groups. The results allow to conclude that the determination of iron and hematological parameters are useful tools for diagnosis and for monitoring patients with iron deficiency anemia. It is recommended that the ADE be included within the profile of exams for such patients in order to assess the degree of anisocitosis in iron deficiency anemia, and thus lead doctors to a quick and accurate diagnosis as quickly as possible.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    Full Text Available A anemia falciforme tem um desenvolvimento clínico extremamente variável que se caracteriza principalmente por diferentes graus de intensidade da anemia hemolítica. As razões dessa variabilidade são parcialmente conhecidas na expressão fenotípica da doença. Apesar de ter um mesmo defeito genético, a anemia falciforme pode estar associada com níveis diferentes de Hb Fetal e interações com talassemia alfa que atuam como modeladores genéticos da doença. Entretanto, outros defeitos genéticos dos eritrócitos, com destaques para a deficiência de G-6PD, a esferocitose e as deficiências de enzimas anti-oxidantes (SOD, GPx e catalase certamente interferem no curso clínico da doença. Os diferentes haplótipos da Hb S denominados por Banto, Benin, Senegal, Camarões e Asiático, tem sido apontados também como possíveis causas da heterogeneidade fenotípica da anemia falciforme. Toda essa diversidade que caracteriza a anemia falciforme está, em parte, relacionada à sua origem multicêntrica e que envolvem populações com diferentes anormalidades genéticas de proteínas e enzimas eritrocitárias. Por outro lado, além desses fatores caracterizados como interferentes eritrocitários, há os interferentes do meio ambiente em que está inserido o doente com anemia falciforme. Entre os interferentes ambientais destacam-se as situações sociais, econômicas e culturais do doente, e que tem influência no curso de sua doença. Diante desse quadro complexo e interativo, o presente artigo mostra a influência de certos interferentes eritrocitários e ambientais na anemia falciforme. Ao finalizar o artigo é proposto um protocolo de monitoramento laboratorial das síndromes falcêmicas, com destaque para a anemia falciforme.

    The relationship between radiation exposure and aplastic anemia, clarified previously, is discussed. When persons such as radiological technicians receive whole-body irradiation in rather large doses, it is possible that aplastic anemia will result later on. However, this is difficult to determine because the irradiated region is limited despite large doses of radiation. (Bell, E.)

    Full Text Available Anemia is a common health problem among women throughout the world, however, there has been minimal research on women's concepts of anemia. The purpose of this study was to examine concepts of anemia in low income Nicaraguan women. A qualitative design was used. Audio-taped open-ended interviews in Spanish with 14 women were used to obtain data. Tapes were transcribed and content analyzed. The findings indicate that few of the women had biomedically accurate concepts of anemia, such as that it was due to lack of iron from poor eating. Others held folk medical beliefs including home remedies, for example drinking the milk of a mare or beet juice and eating certain foods such as bean soup. Most of the women did not know any symptoms of anemia and a few reported that it can develop into leukemia. These concepts of anemia are instructive for nurses working with patients from Nicaragua and will be useful in developing nursing interventions to alleviate this public health problem.La anemia es un problema de salud común entre las mujeres alrededor del mundo, sin embargo, se han realizado pocas investigaciones sobre los conceptos de anemia entre las mujeres.

    Aplastic Fanconi anemia (FA) accompanying malformation was firstly reported in 1927. This review concerns the recent findings on FA. FA belongs to the chromosomal instability syndrome and its detailed molecular mechanism is still unknown. The disease has been defined to be highly sensitive to radiation, however, which is quite an important problem since irradiation with a large dose of radiation is required before its radical treatment (bone marrow transplantation). FA cells are also mitomycin C-sensitive and FA patients are said to be the mosaic of the sensitive and normal cells. This enables to classify FA into 8 types of A-H groups, whose genotypes (FAA-FAH, FANCA-FANCH) are becoming clear. However, the intracellular function of the FANC-expressed protein, although known to form a big complex, is not elucidated yet. There is an abnormality in DNA processing such as re-linkage of the double strand-broken DNA in FA cells. FA causal gene FANCG is found identical to XRCC9 which is associated to high sensitivity to radiation. Analysis of FANC genes will provide useful findings on molecular mechanism of DNA-repair.

    There is a wide heterogeneity in the reports of celiac disease prevalence in iron-deficiency anemia patients. To determine the prevalence of celiac disease in patients with iron-deficiency anemia. Adult patients with a diagnosis of iron-deficiency anemia were enrolled for upper endoscopy with duodenal biopsies. Healthy volunteers that underwent upper endoscopy were enrolled as controls. A total of 135 patients with iron-deficiency anemia and 133 controls were enrolled. Celiac disease prevalence was higher in the iron-deficiency anemia group [11.11 vs. 1.51%, OR: 8.18 (1.83-36.55), P=.001). Of the celiac disease patients in the iron-deficiency anemia group, 73.3% had at least one endoscopic sign suggesting villous atrophy, whereas 100% of the celiac disease patients in the control group presented with at least one endoscopic sign. Patients with iron-deficiency anemia have an increased risk for celiac disease. Up to 25% of these patients may not present any endoscopic sign suggesting villous atrophy.

    Full Text Available Objective: To identify the prevalence and factors associated with anemia in children attending Municipal Early Childhood Education Day Care Center (Centros Municipais de Educação Infantil [CMEI] nurseries in Colombo-PR. Methods: Analytical, cross-sectional study with a representative sample of 334 children obtained by stratified cluster sampling, with random selection of 26 nurseries. Data collection was conducted through interviews with parents, assessment of iron intake by direct food weighing, and hemoglobin measurement using the finger-stick test. Bivariate association tests were performed followed by multiple logistic regression adjustment. Results: The prevalence of anemia was 34.7%. Factors associated with anemia were: maternal age younger than 28 years old (p = 0.03, male children (p = 0.02, children younger than 24 months (p = 0.01, and children who did not consume iron food sources (meat + beans + dark green leafy vegetables (p = 0.02. There was no association between anemia and iron food intake in CMEI. However, iron intake was well below the recommended levels according to the National Education Development Fund resolution, higher prevalence of anemia was observed in children whose intake of iron, heme iron, and nonheme iron was below the median. Conclusions: In terms of public health, the prevalence of anemia is characterized as a moderate problem in the studied population and demonstrates the need for coordination of interdisciplinary actions for its reduction in CMEI nurseries.

    Severe anemia is a major cause of sickness and death in African children, yet the causes of anemia in this population have been inadequately studied. We conducted a case-control study of 381 preschool children with severe anemia (hemoglobin concentration, <5.0 g per deciliter) and 757 preschool children without severe anemia in urban and rural settings in Malawi. Causal factors previously associated with severe anemia were studied. The data were examined by multivariate analysis and structural equation modeling. Bacteremia (adjusted odds ratio, 5.3; 95% confidence interval [CI], 2.6 to 10.9), malaria (adjusted odds ratio, 2.3; 95% CI, 1.6 to 3.3), hookworm (adjusted odds ratio, 4.8; 95% CI, 2.0 to 11.8), human immunodeficiency virus infection (adjusted odds ratio, 2.0; 95% CI, 1.0 to 3.8), the G6PD -202/-376 genetic disorder (adjusted odds ratio, 2.4; 95% CI, 1.3 to 4.4), vitamin A deficiency (adjusted odds ratio, 2.8; 95% CI, 1.3 to 5.8), and vitamin B 12 deficiency (adjusted odds ratio, 2.2; 95% CI, 1.4 to 3.6) were associated with severe anemia. Folate deficiency, sickle cell disease, and laboratory signs of an abnormal inflammatory response were uncommon. Iron deficiency was not prevalent in case patients (adjusted odds ratio, 0.37; 95% CI, 0.22 to 0.60) and was negatively associated with bacteremia. Malaria was associated with severe anemia in the urban site (with seasonal transmission) but not in the rural site (where malaria was holoendemic). Seventy-six percent of hookworm infections were found in children under 2 years of age. There are multiple causes of severe anemia in Malawian preschool children, but folate and iron deficiencies are not prominent among them. Even in the presence of malaria parasites, additional or alternative causes of severe anemia should be considered.

    The association between obesity and different types of anemia remained uncertain. The present study aimed to assess the relation between obesity parameters and the occurrence of iron deficiency anemia and also megaloblastic anemia among Iranian population. This cross-sectional study was performed on 1252 patients with morbid obesity that randomly selected from all patients referred to Clinic of obesity at Rasoul-e-Akram Hospital in 2014. The morbid obesity was defined according to the guideline as body mass index (BMI) equal to or higher than 40 kg/m2. Various laboratory parameters including serum levels of hemoglobin, iron, ferritin, folic acid, and vitamin B12 were assessed using the standard laboratory techniques. BMI was adversely associated with serum vitamin B12, but not associated with other hematologic parameters. The overall prevalence of iron deficiency anemia was 9.8%. The prevalence of iron deficiency anemia was independent to patients' age and also to body mass index. The prevalence of vitamin B12 deficiency was totally 20.9%. According to the multivariable logistic regression model, no association was revealed between BMI and the occurrence of iron deficiency anemia adjusting gender and age. A similar regression model showed that higher BMI could predict occurrence of vitamin B12 deficiency in morbid obese patients. Although iron deficiency is a common finding among obese patients, vitamin B12 deficiency is more frequent so about one-fifth of these patients suffer vitamin B12 deficiency. In fact, the exacerbation of obesity can result in exacerbation of vitamin B12 deficiency.

    Anemia affects almost two-thirds of pregnant women in developing countries and contributes to maternal morbidity and mortality and to low birthweight. To determine the prevalence of anemia and the dietary and socioeconomic factors associated with anemia in pregnant women living in an urban community setting in Hyderabad, Pakistan. This was a prospective, observational study of 1,369 pregnant women enrolled at 20 to 26 weeks of gestation and followed to 6 weeks postpartum. A blood sample was obtained at enrollment to determine hemoglobin levels. Information on nutritional knowledge, attitudes, and practice and dietary history regarding usual food intake before and during pregnancy were obtained by trained interviewers within 1 week of enrollment. The prevalence of anemia (defined by the World Health Organization as hemoglobin hemoglobin from 9.0 to 10.9 g/dL) and 14.8% had moderate anemia (hemoglobin from 7.0 to 8.9 g/dL). Only 0.7% were severely anemic (hemoglobin education, pregnancy history, iron supplementation, and height showed that drinking more than three cups of tea per day before pregnancy (adjusted prevalence odds ratio [aPOR], 3.2; 95% confidence interval [CI], 1.3 to 8.0), consumption of clay or dirt during pregnancy (aPOR, 3.7; 95% CI, 1.1 to 12.3), and never consuming eggs or consuming eggs less than twice a week during pregnancy (aPOR, 1.7; 95% CI, 1.1 to 2.5) were significantly associated with anemia. Consumption of red meat less than twice a week prior to pregnancy was marginally associated with anemia (aPOR, 1.2; 95% CI, 0.8 to 1.8) but was significantly associated with lower mean hemoglobin concentrations (9.9 vs. 10.0 g/dL, p = .05) during the study period. A subanalysis excluding women with mild anemia found similar associations to those of the main model, albeit even stronger. A high percentage of women at 20 to 26 weeks of pregnancy had mild to moderate anemia. Pica, tea consumption, and low intake of eggs and red meat were associated with

    2015-01-01

    Anemia affects one-fourth of the world’s population, and iron deficiency is the predominant cause. Anemia is associated with chronic fatigue, impaired cognitive function, and diminished well-being. Patients with iron deficiency anemia of unknown etiology are frequently referred to a gastroenterologist because in the majority of cases the condition has a gastrointestinal origin. Proper management improves quality of life, alleviates the symptoms of iron deficiency, and reduces the need for blood transfusions. Treatment options include oral and intravenous iron therapy; however, the efficacy of oral iron is limited in certain gastrointestinal conditions, such as inflammatory bowel disease, celiac disease, and autoimmune gastritis. This article provides a critical summary of the diagnosis and treatment of iron deficiency anemia. In addition, it includes a management algorithm that can help the clinician determine which patients are in need of further gastrointestinal evaluation. This facilitates the identification and treatment of the underlying condition and avoids the unnecessary use of invasive methods and their associated risks. PMID:27099596

    Leal Esteban, Lucía Carolina

    2010-12-01

    Full Text Available La vitamina A desempeña un papel fundamental en el desarrollo de los tejidos y órganos gracias a su capacidad de promover la diferenciación celular y regular la apoptosis. Específicamente en el sistema inmune, esta vitamina tiene efectos muy importantes sobre componentes específicos tanto de la respuesta inmune innata como de la adaptativa. En la inmunidad innata, el ácido retinoico (AR participa en la regeneración de las mucosas y epitelios, promueve la diferenciación de células como los neutrófilos y eosinófilos y potencia la fagocitosis. Además, ayuda a la migración de las diferentes células inmunes promoviendo la producción de metaloproteinasas de matriz extracelular. Aunque sus efectos en las células NK son más controversiales, se ha encontrado que el número y la función lítica de estas células disminuyen cuando hay deficiencia de vitamina A (DVA. Por otra parte, el AR influencia el desarrollo de la inmunidad adaptativa alterando el perfil de producción de citoquinas por parte de las células presentadoras de antígeno, lo que influye en la diferenciación de los linfocitos T ayudadores. En general, se ha observado que el AR amplifica la proliferación de las células T y potencia el desarrollo de células plasmáticas a partir de los linfocitos B maduros. Todos estos efectos tienen repercusiones importantes en la adecuada defensa contra las infecciones, especialmente en la infancia en la cual la DVA es un problema importante de salud pública, no solo en Colombia sino también en aproximadamente otros 60 países.

    Background: A lack of information on the etiology of anemia has hampered the design and monitoring of anemia-control efforts. Objective: We aimed to evaluate predictors of anemia in preschool children (PSC) (age range: 6–59 mo) by country and infection-burden category. Design: Cross-sectional data from 16 surveys (n = 29,293) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project were analyzed separately and pooled by category of infection burden. We assessed relations between anemia (hemoglobin concentration anemia (hemoglobin concentration anemia with concomitant iron deficiency (defined as an inflammation-adjusted ferritin concentration anemia in >50% of surveys. Associations between breastfeeding and anemia were attenuated by controlling for child age, which was negatively associated with anemia. The most consistent predictors of severe anemia were malaria, poor sanitation, and underweight. In multivariable pooled models, child age, iron deficiency, and stunting independently predicted anemia and severe anemia. Inflammation was generally associated with anemia in the high- and very high–infection groups but not in the low- and medium-infection groups. In PSC with anemia, 50%, 30%, 55%, and 58% of children had concomitant iron deficiency in low-, medium-, high-, and very high–infection categories, respectively. Conclusions: Although causal inference is limited by cross-sectional survey data, results suggest anemia-control programs should address both iron deficiency and infections. The relative importance of factors that are associated with anemia varies by setting, and thus, country-specific data are needed to guide programs. PMID:28615260

    Full Text Available OBJETIVO: Determinar la prevalencia de anemia en niños campesinos de edad escolar en la región amazónica de Ecuador. MÉTODOS: Se realizó un estudio transversal durante los meses de mayo a octubre de 2000 en dos cantones de la provincia de Orellana, al noreste de Ecuador. Se eligieron 17 escuelas aleatoriamente hasta completar el tamaño muestral deseado, que fue de 626 niños. Se recogieron los datos demográficos y antropométricos (peso y talla; se determinaron los valores de hemoglobina y de protoporfirina eritrocitaria, y se analizaron muestras de heces en busca de infestación por parásitos. RESULTADOS: La prevalencia general de anemia fue de 16,6% y de los escolares afectados, 75,5% tenían anemia por déficit de hierro. La prevalencia de desnutrición crónica moderada fue de 28,8% y la de desnutrición crónica grave, de 9,3%. Asimismo, se encontró una prevalencia de desnutrición aguda moderada de 8,4% y de desnutrición aguda grave de 3,4%. Las infecciones parasitarias fueron muy frecuentes (82,0%. Los parásitos más comunes fueron Entamoeba coli (30,3% y Ascaris lumbricoides (25,0%. No se encontró ninguna relación entre la prevalencia de anemia y anemia por déficit de hierro por un lado, y los indicadores nutricionales o de infección parasitaria por el otro. CONCLUSIÓN: La anemia no es un problema grave de salud pública en la población estudiada. No obstante, la elevada prevalencia de niños con desnutrición crónica apunta a la necesidad de mejorar las características de la dieta. La falta de asociación entre la prevalencia de desnutrición y la anemia podría deberse a una baja biodisponibilidad o absorción de hierro, más que a una ingestión insuficiente. Se necesitan estudios que evalúen el tipo de dieta consumida habitualmente por esta población.

    Full Text Available Fanconi Anemia (FA is a rare autosomic recessive and X-linked disease with chromosomal instability after exposure to crosslinking agents as the hallmark. Clinical features of FA are somatic malformations, progressive bone marrow failure and cancer proneness, however there is wide clinical heterogeneity. The symptom most frequently and early associated with morbidity and mortality is progressive pancytopenia in the first decade of life although acute myelogenous leukemia (AML or myelodysplastic syndrome (MDS can appear before aplastic anemia. Squamous cell carcinoma (SCC of the head-neck, intestinal or genital tract has a very high incidence in FA and can appear at young age. This paper will focus on treatment of bone marrow failure in FA.

O diagnóstico diferencial das referidas anemias é de grande importância clínica; contudo, muitas vezes é complexo em virtude de concomitância de doenças, além de demandar tempo e apresentar custos significativos. Com o propósito de conferir maior simplicidade e eficiência ao diagnóstico diferencial destas anemias, o uso de índices derivados de modernos contadores automáticos tem sido sugerido. Entre estes, pode ser citado o índice de anisocitose eritrocitária (RDW, que indica o grau de variabilidade do tamanho das hemácias. Neste estudo, o poder de discriminação deste índice quanto ao tipo de anemia microcítica e hipocrômica foi avaliado em um grupo de 159 pacientes sabidamente portadores de um quadro de anemia causado por deficiência de ferro, beta talassemia menor ou uma anemia de doença crônica. Não foi observada diferença significativa para o RDW entre os três grupos de anemias microcíticas, indicando não ser este índice uma ferramenta útil para a diferenciação entre anemia ferropriva, beta talassemia menor e anemia de doença crônica.Iron deficiency anemia, the thalassemia trait and chronic disease anemia are the most common microcytic and hypochromic anemias in the Brazilian population.

    1976-01-01

    Among the Japanese radiological technicians, four deaths from aplastic anemia have been reported after 1930. On the other hand, during the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However, actually three died from aplastic anemia. This difference is statistically significant at the 1% level. While, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been induced frequently among the Japanese radiological technicians in the era when there was much exposure to occupational radiation. (orig.) [de

    Full Text Available É apresentada uma revisão das recentes aquisições na anemia ancilostomótica, assinalando a importância de alimentação qualitativamente deficiente junto á infestação helmíntica na gênese desta doença. Acentuou-se que a anemia ancilostomótica é uma doença de carência. Profilaxia clássica da Ancilostomose resume-se em evitar a infestação do homem pelos ancilostomídeos. Critica-se a aplicabilidade destas medidas e eficiência das mesmas no que diz respeito á incidência da anemia. O presente trabalho mostra aquisições preliminares sôbre fundamentos de uma profilaxia de carência (tipo profilaxia do bócio endêmico da anemia ancilostomótica, baseada na administração de alimentos contaminados por um sal de ferro. As misturas sulfato ferroso-farinha de mandióca e citrato férrico amoniacal-caldo de feijão, mostraram-se eficientes em prevenir a queda das cifras hemáticas durante largos períodos de tempo em indivíduos maciçamente infestados (6-8 meses. Não foi verificada a dose diária mínima eficiente dêstes sais, obtendo-se resultados satisfatorios mesmo com 0.1 g diária de sulfato ferroso (correspondendo a 0.037 g de ferro metálico. Numerosos alimentos e sais de ferro foram experimentados com resultados infrutíferos por diferentes razões. A influência dos helmintos, pela hemorragias intestinais que acarretam poude ser mais uma vez estudada, nos casos de sais de ferro administrados em doses ineficientes ou em períodos de prova sem medicação marcial. É proposta nova classificação de intensidade de infestação, levando em consideração o conhecido fato de ser a atividade dos helmintos, exclusivamente expoliadora. Em conclusão, nos parece exequível a profilaxia da anemia ancilostomótica mediante ingestão de alimentos contaminados por quantidades eficientes de sais de ferro. Êste método profilático extremamente econômico será na prática, provàvelmente, muito superior aos métodos de profilaxia

    Full Text Available OBJETIVO: Analisar a prevalência de anemia em crianças menores de seis anos, em uma amostra probabilística de área urbana. MÉTODOS: Foi realizado estudo com crianças de zero a cinco anos de idade, na cidade de Pelotas, RS, em 2004. Foram coletadas informações sobre características demográficas, socioeconômicas, antropométricas, de morbidade e sobre alimentação, por meio de questionário aplicado às mães ou responsáveis. As crianças foram pesadas e medidas. A concentração de hemoglobina foi medida com hemoglobinômetro portátil, HemoCue e anemia foi definida como valores de hemoglobina OBJECTIVE: To assess the prevalence of anemia among children under six years of age in a probabilistic sample from an urban area. METHODS: A study was conducted comprising children aged zero to five years in the city of Pelotas, Southern Brazil, in 2004. Data were collected on demographic, socioeconomic, and anthropometric characteristics, morbidity and nutrition using a questionnaire applied to the mothers and guardians. Children's weight and height measurements were obtained. Hemoglobin concentration was measured using the HemoCue portable hemoglobinometer and anemia was defined as hemoglobin <11 g/dL. The association between anemia and predictors was expressed as prevalence ratio. Multivariate analysis was carried out using Poisson regression following a conceptual model and taking into account the study design effect. RESULTS: There were identified 534 children and total losses and refusals were 27 (5.1%. The prevalence of anemia was 30.2% (95% CI 23.5%;37.0%. In the multivariate analysis, only age and family income remained significantly associated with anemia. CONCLUSIONS: Anemia was largely socially determined in the population studied. Interventions aiming at reducing anemia should be developed to lessen this condition in the short run targeting disadvantaged populations.

    Full Text Available RESUMEN La investigación científica es una función esencial en salud pública; permite reconocer problemas y situaciones que comprometen la salud y la identificación de soluciones. La investigación es esencial para formulación de políticas desalud. Es imperativo para los países tener sistemas nacionales de investigación. Últimamente, ha habido un significativo avance global, pero el crecimiento no es uniforme, las condiciones son escasas en países con ingresos medianos y bajos. Una experiencia que ilustra esta situación ha sido la investigación de la deficiencia de yodo (DI en Perú y la aplicación de resultados para la creación de un programa de salud pública. La investigación demostró persistente DI, que durante la gestación causa daño cerebral y retardo mental, que el uso de aceite yodado en la prevención y tratamiento tiene efecto inmediato y larga duración, y validó la concentración urinaria del yodo como el mejor indicador de nutrición de yodo. Estos resultados fueron tomados en cuenta por el Ministerio de Salud y en 1983 se creó el Programa Nacional de Control del Bocio y Cretinismo Endémicos, que ha logrado la eliminación virtual de la DI desde 1995.

    Full Text Available Incidents of heart and renal failure (HF, RF together, are increasing in our country and all over the world, so a great attention has been dedicated to this problem recently. These diseases together have shown bad results because of the process of accelerated arteriosclerosis, structural changes of myocardium, oxidative stress, inflammation, increased activities of sympathetic nervous system (SNS, increased activities of a renin-angiotensin-aldosterone system (RAAS. These factors are crucial in the development of patho-physiological process and consequential development of anemia, that together with heart and renal failure through interaction, cause serious disorder that we call the cardio-renal anemia syndrome. We examined effects of erythropoietin (Epoetin beta at 90 (60 men and 30 women pre-dialysed and dialysed patients with HF signs during a period of three years in individual dozes of 2000-6000 units subcutaneous (sc weekly. Using computer S PLUS and SAS multiple variant analysis we have got correlations by Pearson. Epoetin beta significantly develops anemiaparameters: number of erythrocytes (r=0.51779; p<0.0001, hemoglobin (r=0.38811; p<0.0002, MCV (r=0.59876; p<0.0001 at patients with HF. Positive effects are seen at NYHA class (r=0.59906; p<0.0001, on quality of life before and after prescribing medicine. Parameters of renal functions are improving: more urea (r =0.45557; p<0.0001 than creatinine (r=0.26397; p<0.00119 and potassium values K(+ are not changed significantly (r=0.02060; p<0.8471. Epoetin beta has been useful in treatment of pre-dialysed and dialysed patients with HF and anemia by improving functional ability of myocardium and quality of life.

    Full Text Available Anemia is very commonly encountered in general clinical practice among all age groups. The more commonly used way to classify anemia has been to categorize it as being microcytic (mean corpuscular volume [MCV] 100 fL, which in turn allows for a more practical way to attempt to come up with a cause for any decrease in hemoglobin. Microcytic anemias are usually due to iron deficiency (in turn, a result of a number of different etiologies ranging from decreased intake, malabsorption, or blood loss, hemoglobinopathies (thalassemic syndromes, and some cases of severe anemia resulting from chronic disease. Normocytic anemia is often a result of anemia of chronic disease, hemolysis, or secondary to bone marrow failure. Macrocytic anemias are frequently caused by deficiencies of folic acid and/or Vitamin B12, exposure to toxic agents like drugs that interfere with DNA metabolism and alcohol, as also bone marrow failure states, such as from myelodysplastic syndrome. A comprehensive history, physical examination, and directed laboratory evaluation will help to identify a specific cause for anemia.

    Radio-iron utilization was nearly normal in these patients, only bilateral nephrectomized patients showed a reduced radio-iron utilization. Red blood half-life span was shortened in all patients, well corresponding to the degree of anemia. Parameters of erythropoesis like plasma iron clearance, bone marrow transit time, erythron iron turnover, non-erythron iron turnover and hemolysis iron turnover failed to quantitate disorders of red blood cell regeneration in these patients. No defect in red blood cell enzyme activity could be demonstrated. Enzymes of glycolysis were increased corresponding to the reduced erythrocyte half-life span. (orig.) [de

Porém, apesar de percentual modesto, indícios epidemiológicos apontam no sentido inverso, ou seja, indicam a crescente e grave ocorrência de anemia em diferentes regiões do mundo, inclusive no Brasil. Ao reunir esses informes, constata-se que a anemia continua, desde a antiguidade, a ser uma das entidades nosológicas mais prevalentes e difundidas nas populações humanas. A partir daí surge uma série de questionamentos ainda sem respostas em relação às reais prevalência e etiopatogenia do problema, ao grau de implantação e à efetividade das medidas de controle.In 1990, the United Nations held a World Summit in New York, in which goals for the upcoming decade were established. One of these goals was a one-third reduction in the prevalence of anemia among women at childbearing age. Despite this modest percentage, epidemiological indicators point to the opposite direction, indicating an increasing occurrence of anemia in different regions of the world, including in Brazil. These data show that anemia has continued since the antiquity to be one of the most prevalent and widespread diseases in human populations. Thus, a number of questions without answers arise regarding the actual prevalence and etiopathogenesis of the problem as well as with respect to the degree of implantation and the effectiveness of control measures.

    2016-05-01

    Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial.

  16. Genetic diagnosis for congenital hemolytic anemia.

    Science.gov (United States)

    Ohga, Shouichi

    2016-01-01

    Congenital hemolytic anemia is a group of monogenic diseases presenting with anemia due to increased destruction of circulating erythrocytes. The etiology of inherited anemia accounts for germline mutations of the responsible genes coding for the structural components of erythrocytes and extra-erythrocytes. The erythrocyte abnormalities are classified into three major disorders of red cell membrane defects, hemoglobinopathies, and red cell enzymopathies. The extra-erythrocyte abnormalities, typified by consumption coagulopathy and intravascular hemolysis, include Upshaw-Schulman syndrome and atypical hemolytic uremic syndrome. The clinical manifestations of congenital hemolytic anemia are anemia, jaundice, cholelithiasis and splenomegaly, while the onset mode and severity are both variable. Genetic overlapping of red cell membrane protein disorders, and distinct frequency and mutation spectra differing among races make it difficult to understand this disease entity. On the other hand, genetic modifiers for the phenotype of β-globin diseases provide useful information for selecting the optimal treatment and for long-term management. Recently, next generation sequencing techniques have enabled us to determine the novel causative genes in patients with undiagnosed hemolytic anemias. We herein review the concept and strategy for genetic diagnosis of inherited hemolytic anemias.

A 44-year-old Indian man diagnosed with autoimmune hemolytic anemia presented with a 1-week history of blurred vision in both eyes. Fundus biomicroscopy revealed bilateral peripheral retinal venous sheathing and cellophane maculopathy. Fundus fluorescent angiogram showed bilateral late leakage from the peripheral venous arcades and submacular fluid accumulation. The retinal phlebitis resolved following a blood transfusion and administration of systemic steroids. Retinopathy associated with autoimmune hemolytic anemia is not well known. This is thought to be the first documentation of retinal phlebitis occurring in this condition.

    Of 155 adults with sickle-cell anemia (SS, SC), radiographs of the pelvis or hip demonstrated protrusio acetabuli on at least one side in 14 (3 men and 11 women), as indicated by projection of the acetabular line medial to the ilio-ischial line. All 14 patients had bone changes attributable to sickle-cell anemia, including marrow hyperplasia and osteonecrosis; however, the severity of femoral or acetabular osteonecrosis did not appear directly related to the protrusion. The authors conclude that sickle-cell anemia can predispose to development of protrusio acetabuli

    Acquired aplastic anemia is a potentially fatal bone marrow failure disorder that is characterized by pancytopenia and a hypocellular bone marrow. Hematopoietic stem-cell transplantation or bone marrow transplantation (BMT) is the treatment of choice for young patients who have a matched sibling donor. Immunosuppression with either anti-thymocyte globulin and cyclosporine or high-dose cyclophosphamide is an effective therapy for patients who are not suitable BMT candidates owing to age or lack of a suitable donor. Results of BMT from unrelated and mismatched donors are improving, but presently this treatment option is best reserved for those patients who do not respond, relapse or develop secondary clonal disorders following immunosuppressive therapy. Efforts are currently underway to both improve immunosuppressive regimens and to expand the application of BMT. PMID:21495931

    Utilizing longitudinal data from the nationally-representative Mexico Family Life Survey, this study assesses the association between family structure and iron-deficient anemia among children ages 3-12 in Mexico. The longitudinal models (n = 4649), which control for baseline anemia status and allow for consideration of family structure transitions, suggest that children living in stable-cohabiting and single-mother families and those who have recently experienced a parental union dissolution have higher odds of anemia than those in stable-married, father-present family structures. Interaction effects indicate that unmarried family contexts have stronger associations with anemia in older children (over age five); and, that the negative effects of parental union dissolution are exacerbated in poorer households. Resident maternal grandparents have a significant beneficial effect on child anemia independent of parental family structure. These results highlight the importance of family structure for child micronutrient deficiencies and suggest that understanding social processes within households may be critical to preventing child anemia in Mexico.

    Graves' disease is often associated with other autoimmune disorders, including rare associations with autoimmune hemolytic anemia (AIHA). We describe a unique presentation of thyroid storm and warm AIHA diagnosed concurrently in a young female with hyperthyroidism. The patient presented with nausea, vomiting, diarrhea and altered mental status. Laboratory studies revealed hemoglobin 3.9g/dL, platelets 171×10 9 L -1 , haptoglobin storm and warm AIHA. She was started on glucocorticoids to treat both warm AIHA and thyroid storm, as well as antithyroid medications, propranolol and folic acid. Due to profound anemia and hemodynamic instability, the patient was transfused two units of uncrossmatched packed red blood cells slowly and tolerated this well. She was discharged on methimazole as well as a prolonged prednisone taper, and achieved complete resolution of the thyrotoxicosis and anemia at one month. Hyperthyroidism can affect all three blood cell lineages of the hematopoietic system. Anemia can be seen in 10-20% of patients with thyrotoxicosis. Several autoimmune processes can lead to anemia in Graves' disease, including pernicious anemia, celiac disease, and warm AIHA. This case illustrates a rarely described presentation of a patient with Graves' disease presenting with concurrent thyroid storm and warm AIHA. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Anemia at hospitalization is often treated as an accompaniment to an underlying illness, without active investigation, despite its association with morbidity. Development of hospital-acquired anemia (HAA) has also been associated with increased risk for poor outcomes. Together, they may further heighten morbidity risk from bad to worse. The aims of this study were to (1) examine mortality, length of stay, and total charges in patients with present-on-admission (POA) anemia and (2) determine whether these are exacerbated by development of HAA. In this cohort investigation, from January 1, 2009, to August 31, 2011, a total of 44,483 patients with POA anemia were admitted to a single health system compared with a reference group of 48,640 without POA anemia or HAA. Data sources included the University HealthSystem Consortium database and electronic medical records. Risk-adjustment methods included logistic and linear regression models for mortality, length of stay, and total charges. Present-on-admission anemia was defined by administrative coding. Hospital-acquired anemia was determined by changes in hemoglobin values from the electronic medical record. Approximately one-half of the patients experienced worsening of anemia with development of HAA. Risk for death and resource use increased with increasing severity of HAA. Those who developed severe HAA had 2-fold greater odds for death; that is, mild POA anemia with development of severe HAA resulted in greater mortality (odds ratio, 2.57; 95% confidence interval, 2.08-3.18; P < 0.001), increased length of stay (2.23; 2.16-2.31; P < 0.001), and higher charges (2.09; 2.03-2.15; P < 0.001). Present-on-admission anemia is associated with increased mortality and resource use. This risk is further increased from bad to worse when patients develop HAA. Efforts to address POA anemia and HAA deserve attention.

    Objective: To study the effect of oxygen-carrying ability of blood efficacy of radiotherapy for patients with nasopharyngeal carcinoma. Methods: Altogether 161 cases of patients with nasopharyngeal carcinoma were classified according to severity of anemia, and Hb, RBC, MCH, HCT, MCV, MCHC and RDW were tested before, during and after radiotherapy. The patients were followed-up for up to 5 years, the relationship and mechanism among anemia, radiotherapy effects and survival rate was discussed. Results: The survival rate between anemia group and non-anemia group was different significantly (P<0.05). Anemia before radiotherapy, anemia appearance or anemia deterioration during radiotherapy were sensitive factors affecting radiotherapy results. The anemia more severe, the radiotherapy worse. Conclusion: Anemia-hypohemoglobinemia leads to decrease of oxygen-carrying capacity of blood, resulting in oxygen deficiency of tumor cells and their radiotherapy resistance. Therefore this method is worthy of further studies

    Full Text Available OBJETIVO: Revisar aspectos do consumo de leite de vaca associados à anemia na infância. FONTES DOS DADOS: As informações foram coletadas a partir de artigos publicados nas 2 últimas décadas, pesquisados nas bases de dados Lilacs e MEDLINE, livros técnicos e publicações de organizações internacionais. SÍNTESE DOS DADOS: A anemia ferropriva é um grave problema de saúde pública nos países em desenvolvimento. Até os 6 meses de idade, o leite materno supre as necessidades de ferro das crianças nascidas a termo. A partir daí, torna-se necessária a ingestão de uma alimentação complementar rica em ferro. Considerando a importância da dieta na determinação da anemia e o alto consumo de leite de vaca na infância, discute-se neste artigo a relação desse alimento com a deficiência de ferro. A introdução precoce ou a substituição do leite materno por leite de vaca pode ocasionar problemas gastrintestinais e alérgicos. Além disso, esse alimento apresenta baixa biodisponibilidade e densidade de ferro, excesso de proteínas e minerais, especialmente cálcio, interferindo na absorção do ferro de outros alimentos, e associa-se às micro-hemorragias intestinais, principalmente nas crianças menores. CONCLUSÕES: A utilização do leite de vaca em detrimento de outros alimentos ricos em ferro biodisponível constitui um risco para o desenvolvimento da anemia. O estímulo ao aleitamento materno exclusivo até os 6 meses de vida e sua continuidade até pelo menos 24 meses, juntamente com uma dieta complementar rica em ferro são medidas de grande importância para a prevenção da anemia e de suas conseqüências na infância.OBJECTIVE: To thoroughly investigate the association between the consumption of cow's milk and anemia in childhood.

    Full Text Available

    Acquired aplastic anemia(aAA is a severe and rare disease, characterized by hematopoietic bone marrow failure and peripheral cytopenia. The pathophysiology is immune mediated in most cases, activated T1 lymphocytes have been identified as effector cells . The disease can be successfully treated with combined immunosuppressive therapy or allogeneic hematopoietic stem cell transplantation.

    Hepatitis-associated aplastic anemia (HAA  is a syndrome of bone marrow failure following the development of acute seronegative hepatitis. HAA syndrome most often affects young males who presented severe pancytopenia two to three months after an episode of acute hepatitis. The clinical course of hepatitis is more frequently benign but a fulminant severe course is also described. The bone marrow failure can be explosive and severe and it is usually fatal if untreated, no correlations have been observed between severity of hepatitis and AA.

    In none of the  studies a specific virus could be identified and most cases are seronegative for known hepatitis viruses. The clinical characteristics  and response to immunotherapy indicate a central role for immune-mediated mechanism in the pathogenesis of HAA. The initial

Todos los estudios fueron efectuados por el Instituto Caribeño de Alimentación y Nutrición, o en colaboración con él. En todas las encuestas, que fueron similares en su estructura y resultados, se recolectaron muestras de sangre con el fin de determinar las deficiencias de micronutrientes. También se aplicaron cuestionarios para recoger información sobre los patrones de alimentación. Los principales grupos estudiados fueron los niños pequeños, los escolares y las mujeres embarazadas. La anemia por deficiencia de hierro fue la deficiencia de micronutrientes más común de las que se encontraron en los tres estudios. Aunque se hallaron pocos casos de deficiencia de vitamina A grave, fueron más comunes las deficiencias marginales. En los tres estudios se hicieron recomendaciones similares para hacer frente a las deficiencias detectadas en los diversos países. Es menester que los gobiernos y otras agencias sigan promoviendo la disponibilidad y el consumo de alimentos ricos en vitamina A y caroteno. Los programas contra la anemia deben dirigirse específicamente hacia los niños de 1 a 4 años de edad y las mujeres embarazadas.

O objetivo deste trabalho foi estimar a prevalência e características da anemia em idosos do Programa de Saúde da Família de Camaragibe, PE. O delineamento foi transversal, com amostra aleatória sistemática de 284 idosos > 60 anos, de ambos os sexos, realizado em novembro/dezembro-2003. A anemia foi avaliada pela hemoglobina (Hb, concentração de hemoglobina corpuscular média (CHCM, volume corpuscular médio (VCM e amplitude de distribuição eritrocitária (RDW.

    Iron deficiency and immune activation are the two most frequent causes of anemia, both of which are based on disturbances of iron homeostasis. Iron deficiency anemia results from a reduction of the body's iron content due to blood loss, inadequate dietary iron intake, its malabsorption, or increased iron demand. Immune activation drives a diversion of iron fluxes from the erythropoietic bone marrow, where hemoglobinization takes place, to storage sites, particularly the mononuclear phagocytes system in liver and spleen. This results in iron-limited erythropoiesis and anemia. This review summarizes current diagnostic and pathophysiological concepts of iron deficiency anemia and anemia of inflammation, as well as combined conditions, and provides a brief outlook on novel therapeutic options.

    A 16-year-old boy who was diagnosed to have sickle cell anemia was referred to our center. The parental consanguinity, growth retardation and dysmorphic features prompted a search for possible Fanconi's Anemia (FA). The diepoxybutane (DEB) test was positive, confirming FA. The interaction of both diseases might account for his relatively mild phenotype in terms of both sickle cell anemia (or Hb S, HBB: c.20A > T) and FA. The high Hb F level that might be related to concomitant FA, may have caused a milder phenotype of sickle cell anemia, whereas nitric oxide (NO) depletion as a consequence of sickle cell anemia, may have caused a delay in the bone marrow failure of FA.

    Purpose: To review the impact of anemia/tumor hypoxemia on the quality of life and survival in cancer patients, and to assess the problems associated with the correction of this difficulty. Methods: MEDLINE searches were performed to find relevant literature regarding anemia and/or tumor hypoxia in cancer patients. Articles were evaluated in order to assess the epidemiology, adverse patient effects, anemia correction guidelines, and mechanisms of hypoxia-induced cancer cell growth and/or therapeutic resistance. Past and current clinical studies of radiosensitization via tumor oxygenation/hypoxic cell sensitization were reviewed. All clinical studies using multi-variate analysis were analyzed to show whether or not anemia and/or tumor hypoxemia affected tumor control and patient survival. Articles dealing with the correction of anemia via transfusion and/or erythropoietin were reviewed in order to show the impact of the rectification on the quality of life and survival of cancer patients. Results: Approximately 40-64% of patients presenting for cancer therapy are anemic. The rate of anemia rises with the use of chemotherapy, radiotherapy, and hormonal therapy for prostate cancer. Anemia is associated with reductions both in quality of life and survival. Tumor hypoxemia has been hypothesized to lead to tumor growth and resistance to therapy because it leads to angiogenesis, genetic mutations, resistance to apoptosis, and a resistance to free radicals from chemotherapy and radiotherapy. Nineteen clinical studies of anemia and eight clinical studies of tumor hypoxemia were found that used multi-variate analysis to determine the effect of these conditions on the local control and/or survival of cancer patients. Despite differing definitions of anemia and hypoxemia, all studies have shown a correlation between low hemoglobin levels and/or higher amounts of tumor hypoxia with poorer prognosis.

    Fanconi anemia (FA) is an autosomal recessive disorder caused by defects in at least eight distinct genes FANCA, B, C, D1, D2, E, F and G. The clinical phenotype of all FA complementation groups is similar and is characterized by progressive bone marrow failure, cancer proneness and typical birth defects. The principal cellular phenotype is hypersensitivity to DNA damage, particularly interstrand DNA crosslinks. The FA proteins constitute a multiprotein pathway whose precise biochemical function(s) remain unknown. Five of the FA proteins (FANCA, C, E, F and G) interact in a nuclear complex upstream of FANCD2. FANCB and FANCD1 have not yet been cloned, but it is likely that FANCB is part of the nuclear complex and that FANCD1 acts downstream of FANCD2. The FA nuclear complex regulates the mono-ubiquitination of FANCD2 in response to DNA damage, resulting in targeting of this protein into nuclear foci. These foci also contain BRCA1 and other DNA damage response proteins. In male meiosis, FANCD2 also co-localizes with BRCA1 at synaptonemal complexes. Together, these data suggest that the FA pathway functions primarily as a DNA damage response system, although its exact role (direct involvement in DNA repair versus indirect, facilitating role) has not yet been defined.

    Fanconi anemia (FA) is a condition characterized by genetic instability and short stature, which is due to growth hormone (GH) deficiency in most cases. However, no apparent relationships have been identified between FA complementation group genes and GH. In this study, we thereby considered an association between FA and Laron syndrome (LS) (insulin-like growth factor 1 [IGF-1] deficiency). A 21-year-old female Mexican patient with a genetic diagnosis of FA was referred to our research department for an evaluation of her short stature. Upon admission to our facility, her phenotype led to a suspicion of LS; accordingly, serum levels of IGF-1 and IGF binding protein 3 were analyzed and a GH stimulation test was performed. In addition, we used a next-generation sequencing approach for a molecular evaluation of FA disease-causing mutations and genes involved in the GH-IGF signaling pathway. Tests revealed low levels of IGF-1 and IGF binding protein 3 that remained within normal ranges, as well as a lack of response to GH stimulation. Sequencing confirmed a defect in the GH receptor signaling pathway. To the best of our knowledge, this study is the first to suggest an association between FA and LS. We propose that IGF-1 administration might improve some FA complications and functions based upon IGF-1 beneficial actions observed in animal, cell and indirect clinical models: erythropoiesis modulation, immune function improvement and metabolic regulation.

    Heart failure is an important community health problem. Prevalence and incidence of heart failure have continued to rise over the years. Despite recent advances in heart failure therapy, prognosis is still poor, rehospitalization rate is very high, and quality of life is worse. Co-morbidities in heart failure have negative impact on clinical course of the disease, further impair prognosis, and add difficulties to treatment of clinical picture. Therefore, successful management of co-morbidities is strongly recommended in addition to conventional therapy for heart failure. One of the most common co-morbidities in heart failure is presence of iron deficiency and anemia. Current evidence suggests that iron deficiency and anemia are more prevalent in patients with heart failure and reduced ejection fraction, as well as those with heart failure and preserved ejection fraction. Moreover, iron deficiency and anemia are referred to as independent predictors for poor prognosis in heart failure. There is strong relationship between iron deficiency or anemia and severity of clinical status of heart failure. Over the last two decades, many clinical investigations have been conducted on clinical effectiveness of treatment of iron deficiency or anemia with oral iron, intravenous iron, and erythropoietin therapies. Studies with oral iron and erythropoietin therapies did not provide any clinical benefit and, in fact, these therapies have been shown to be associated with increase in adverse clinical outcomes. However, clinical trials in patients with iron deficiency in the presence or absence of anemia have demonstrated considerable clinical benefits of intravenous iron therapy, and based on these positive outcomes, iron deficiency has become target of therapy in management of heart failure. The present report assesses current approaches to iron deficiency and anemia in heart failure in light of recent evidence.

    Full Text Available Objective: The aim of this study was to analyze the reticulocyte maturity indices (low, medium, and high fluorescence ratios in iron deficient 1- to 6-year-old children, and identify the prevalence of iron deficiency anemia in this population. Methods: The present study included 39 subjects, divided into two groups: control subjects (n = 33, and subjects with iron deficiency anemia (n = 6. The results were analyzed by Student's t-test for comparison of means. Differences were considered significant when two-tailed p-value < 0.05. Results: Subjects with iron deficiency anemia presented increases in the proportion of mean (10.3 ± 4.7% vs. 6.0 ± 3.4%; p-value = 0.003, and high fluorescence reticulocytes (2.3 ± 0.87% vs. 0.9 ± 0.9%; p-value = 0.03 compared to the control group. The prevalence of anemia in this population was 15% (n = 6. Conclusion: The indices related to immaturity of reticulocytes are higher in the presence of iron deficiency, thus demonstrating a deficiency in the raw material to form hemoglobin and are, therefore, possible early markers of iron deficiency and anemia. We emphasize the need to standardize these indices for use in clinical practice and lab test results.

    Sickle cell anemia is an inherited hematologic disorder associated with hemolytic and vaso-occlusive complications. An activation of coagulation is also a prominent feature of sickle cell anemia. Growing evidence indicates that coagulation may contribute to the inflammation and vascular injury in sickle cell anemia. This review focuses on tissue factor expression and its contribution to the activation of coagulation, thrombosis and vascular inflammation in sickle cell anemia.

    Fanconi anemia (FA) is a genetically and phenotypically heterogeneous disorder characterized by congenital malformations, progressive bone marrow failure, and predisposition to cancer, particularly hematological malignancies and solid tumors of the head and neck. The main role of FA proteins is in the repair of DNA interstrand crosslinks (ICLs). FA results from pathogenic variants in at least 16 distinct genes, causing genomic instability. Although the highly variable phenotype makes accurate diagnosis on the basis of clinical manifestations difficult in some patients, diagnosis based on a profound sensitivity to DNA crosslinking agents can be used to identify the pre-anemia patient as well as patients with aplastic anemia or leukemia who may or may not have the physical stigmata associated with the syndrome. Diepoxybutane (DEB) analysis is the preferred test for FA because other agents have higher rates of false-positive and false-negative results. PMID:25827349

    Full Text Available Primary gastric masses are rare in childhood, and a gastric ganglioneuroma has not been reported in the pediatric population. In this report, we describe a 12-year-old female who presented with iron deficiency anemia and melena. Endoscopy was performed to elucidate the source of her symptoms, and revealed a gastric mass with overlying ulceration. Following resection and pathologic examination, the mass was diagnosed as a solitary polypoid ganglioneuroma. A solitary polypoid ganglioneuroma is an uncommon, benign tumor of neural crest cell origin. They are most often asymptomatic and found incidentally, but can present with rectal bleeding, obstruction, pain, and changes in bowel function. Complete resection is the therapy of choice to prevent progression of symptoms or rare transformation into a malignant neuroblastic tumor, like neuroblastoma. As of the patient's last post-operative appointment, she was healthy with resolution of her anemia. Keywords: Ganglioneuroma, Pediatric, Gastric mass, Anemia, Neuroblastic tumor

    Full Text Available We report a rare case of anemia and thrombocytopenia as a result of uterine fibroid and adenomyosis, complicated by immune thrombocytopenic purpura (ITP. Symptoms were presented as menorrhagia and metrorrhagia in a 34-year-old African American woman, who was later treated with blood and platelet transfusion and iron therapy with steroids. Uterine fibroids are commonly found to cause hematologic disturbances such as anemia and reactive thrombocytosis and, less commonly, thrombocytopenia. Moreover, such hematologic disturbances are secondary to heavy and irregular uterine bleeding, which is typically presented. A previous uterine fibroid diagnosis was made and reconfirmed by pelvic and transvaginal ultrasound to exclude other locoregional pathologies. ITP was suggested by Coombs test and several other serologies, leading to confirmation via bone marrow biopsy. In a previous case study, we reported positive responses in hemotecrit and platelet count after the introduction of iron therapy to an iron-depleted middle-aged female presenting severe anemia and thrombocytopenia. 1

    In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells. A 16-year-old with sickle cell disease receiving chronic transfusion of modified intensity (goal to maintain hemoglobin S<50%) who developed symptomatic anemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    Objectives: Anemia is associated with increased mortality in patients with acute symptomatic pulmonary embolism (PE). The purpose of this study was to evaluate the feasibility of Hounsfield unit (HU) measurements on the single unenhanced trigger slice of pulmonary CT angiography scans for diagnosis of anemia. Material and Methods: 150 consecutive patients (median age 64 ± 16 years) with suspected PE underwent pulmonary CT angiography. Two radiologists, blinded to laboratory results, performed HU measurements in the single unenhanced trigger scan independently by region-based analysis (ROI). HU values from ascending and descending aorta and the calculated mean of both were correlated with serum hemoglobin levels. Inter- and intraobserver variability was determined for HU measurements, and ROC analysis was performed for diagnosis of anemia. Calculated linear models were used to assess formulas for estimation of hemoglobin levels from HU measurements. Results: HU measurements revealed high intra- and interrater reliability (ICC > 0.981 and ICC > 0.965, respectively). Calculated mean HU values showed a strong correlation with serum hemoglobin levels (r = 0.734), which allowed generation of different formulas for calculation of hemoglobin levels from HU measurements. ROC analyses confirmed a high sensitivity (80.4 for men; 91.3 for women) and specificity (84.0 for men; 84.9 for women) for diagnosing anemia. Conclusion: Diagnosis of anemia and quantification of hemoglobin levels upon a single unenhanced trigger scan of pulmonary CT angiography is feasible. We suggest disclosing the anemic state in the radiological report, independent of the presence of PE, since anemia carries increased risks of morbidity and mortality.

    Anemia is a prevalent disease with multiple possible etiologies and resultant complications. Iron deficiency anemia is a common cause of anemia and is typically due to insufficient intake, poor absorption, or overt or occult blood loss. Distinguishing iron deficiency from other causes of anemia is integral to initiating the appropriate treatment. In addition, identifying the underlying cause of iron deficiency is also necessary to help guide management of these patients. We review the key components to an evidence-based, cost-conscious evaluation of suspected iron deficiency anemia. Copyright © 2016 Elsevier Inc. All rights reserved.

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD. PMID:26301120

  5. Fanconi anemia proteins in telomere maintenance.

    Sarkar, Jaya; Liu, Yie

    2016-07-01

    Mammalian chromosome ends are protected by nucleoprotein structures called telomeres. Telomeres ensure genome stability by preventing chromosome termini from being recognized as DNA damage. Telomere length homeostasis is inevitable for telomere maintenance because critical shortening or over-lengthening of telomeres may lead to DNA damage response or delay in DNA replication, and hence genome instability. Due to their repetitive DNA sequence, unique architecture, bound shelterin proteins, and high propensity to form alternate/secondary DNA structures, telomeres are like common fragile sites and pose an inherent challenge to the progression of DNA replication, repair, and recombination apparatus. It is conceivable that longer the telomeres are, greater is the severity of such challenges. Recent studies have linked excessively long telomeres with increased tumorigenesis. Here we discuss telomere abnormalities in a rare recessive chromosomal instability disorder called Fanconi Anemia and the role of the Fanconi Anemia pathway in telomere biology. Reports suggest that Fanconi Anemia proteins play a role in maintaining long telomeres, including processing telomeric joint molecule intermediates. We speculate that ablation of the Fanconi Anemia pathway would lead to inadequate aberrant structural barrier resolution at excessively long telomeres, thereby causing replicative burden on the cell.

    Hereditary hemolytic anemias are a group of disorders with a variety of causes, including red cell membrane defects, red blood cell enzyme disorders, congenital dyserythropoietic anemias, thalassemia syndromes and hemoglobinopathies. As damaged red blood cells passing through the red pulp of the spleen are removed by splenic macrophages, splenectomy is one possible therapeutic approach to the management of severely affected patients. However, except for hereditary spherocytosis for which the effectiveness of splenectomy has been well documented, the efficacy of splenectomy in other anemias within this group has yet to be determined and there are concerns regarding short- and long-term infectious and thrombotic complications. In light of the priorities identified by the European Hematology Association Roadmap we generated specific recommendations for each disorder, except thalassemia syndromes for which there are other, recent guidelines. Our recommendations are intended to enable clinicians to achieve better informed decisions on disease management by splenectomy, on the type of splenectomy and the possible consequences. As no randomized clinical trials, case control or cohort studies regarding splenectomy in these disorders were found in the literature, recommendations for each disease were based on expert opinion and were subsequently critically revised and modified by the Splenectomy in Rare Anemias Study Group, which includes hematologists caring for both adults and children.

    Anemia in children younger than 3 years is a public health problem in Peru and worldwide. It is believed that one of the primary causes of anemia is iron deficiency. Numerous studies and reviews have reported that iron deficiency limited psychomotor development in children and that, despite the correction of anemia, children with iron deficiency experienced poorer long-term performance in cognitive, social, and emotional functioning. These outcomes were reported in observational studies, follow-up studies, and experimental studies with a control group. Anemia can decrease school performance, productivity in adult life, quality of life, and the general income of affected individuals. Here we describe possible mechanisms underlying the effect of iron deficiency, with or without anemia, on childhood development. The high rate of anemia in this age group is a cause for concern. Moreover, anemia should be prevented in the first year of life to avoid long-term negative effects on individual development.

    Anemia during hospitalization is associated with poor health outcomes. Does anemia at discharge place patients at risk for hospital readmission within 30 days of discharge? Our objectives were to examine the prevalence and magnitude of anemia at hospital discharge and determine whether anemia at discharge was associated with 30-day readmissions among a cohort of hospitalizations in a single health care system. From January 1, 2009, to August 31, 2011, there were 152,757 eligible hospitalizations within a single health care system. The endpoint was any hospitalization within 30 days of discharge. The University HealthSystem Consortium's clinical database was used for demographics and comorbidities; hemoglobin values are from the hospitals' electronic medical records, and readmission status was obtained from the University HealthSystem Consortium administrative data systems. Mild anemia was defined as hemoglobin of greater than 11 to less than 12 g/dl in women and greater than 11 to less than 13 g/dl in men; moderate, greater than 9 to less than or equal to 11 g/dl; and severe, less than or equal to 9 g/dl. Logistic regression was used to assess the association of anemia and 30-day readmissions adjusted for demographics, comorbidity, and hospitalization type. Among 152,757 hospitalizations, 72% of patients were discharged with anemia: 31,903 (21%), mild; 52,971 (35%), moderate; and 25,522 (17%), severe. Discharge anemia was associated with severity-dependent increased odds for 30-day hospital readmission compared with those without anemia: for mild anemia, 1.74 (1.65-1.82); moderate anemia, 2.76 (2.64-2.89); and severe anemia, 3.47 (3.30-3.65), P < 0.001. Anemia at discharge is associated with a severity-dependent increased risk for 30-day readmission. A strategy focusing on anemia treatment care paths during index hospitalization offers an opportunity to influence subsequent readmissions.

    Full Text Available RACIONAL: As anemias ferropriva, perniciosa e megaloblástica são comuns após procedimentos bariátricos como o bypass e as derivações biliopancreáticas. As principais causas devem-se ao desvio duodenal e do jejuno proximal do trânsito alimentar e, em menor grau, às úlceras anastomóticas. Entretanto a dieta pobre em nutrientes, a suplementação vitamínica inadequada, medicamentos, uso de álcool e neoplasias devem ser lembrados. RELATO DOS CASOS: Os autores relatam dois casos de pacientes pós-procedimentos bariátricos com anemia severa sem controle clínico e cuja investigação identificou melanoma metastático em um caso e neoplasia colônica no segundo, ambos tratados cirurgicamente com bons resultados. CONCLUSÃO: Anemias são comuns após procedimentos bariátricos, porém causas atípicas como neoplasias devem ser suspeitadas nos pacientes mais idosos e principalmente naqueles refratários ao controle clínico.BACKGROUND: Iron deficiency anemia, pernicious and megaloblastic are common after gastric bypass and biliopancreatic diversion. The main causes are due to duodenal exclusion and anastomotic ulcers. However, low protein diet, vitaminic supplementation, medicines, alcohol and tumors must be remembered. CASES REPORT: The authors relate two cases of severe anemia after bariatric procedures that were diagnosed as metastatic melanoma in small bowel and a colorectal cancer treated surgically with good results. CONCLUSION: Anemias are common after bariatric surgery, however unusual causes like tumors must be suspected in the elderly and in those patients that clinical treatment didn't have good results.

    Full Text Available A deformabilidade é a característica que permite ao eritrócito normal de 7 a 8 micrômetros (µm circular por capilares de até 3 µm de diâmetro. Esse fenômeno depende da geometria celular, da viscosidade interna e de propriedades visco-elásticas da membrana eritrocitária. Dentre as técnicas de estudo da deformabilidade eritrocitária (DE, como aspiração por micropipeta, filtração e reoscopia, destaca-se a ectacitometria. Esta técnica utiliza um viscosímetro de fluxo laminar no qual as modificações de forma dos eritrócitos são monitoradas continuamente por um feixe de raio laser, processadas por microcomputador, gerando o "Índice de Deformabilidade" (ID, que mede a eliptocitogênese dos eritrócitos quando submetidos a uma força denominada "shear stressl". Alterações de DE foram descritas em diversas situações, como em anemias hemolíticas hereditárias ou auto-imunes. Na anemia ferropriva, os trabalhos são controversos. O presente estudo avalia a DE em 21 pacientes portadores de anemia ferropriva, utilizando a ectacitometria. Os resultados obtidos a partir do ID demonstram DE diminuída nesses doentes, quando comparada ao grupo controle (pDeformability allows the 7 to 8 µm red cell to cirDeformability allows the 7- to 8-µm red blood cells to circulate through capillaries of 3 µm. This phenomenon depends on cellular geometry, internal viscosity and viscoelastic properties of the membrane. Among the various techniques of erythrocyte deformability analysis, such as micropipette aspiration, filtration and reoscopy, we chose ektacytometry. This technique uses a laminar flow viscometry, where red blood cell shape changes are continuously monitored by laser, processed by a computer, generating the "Deformability Index", which shows the elliptocytogenesis of the erythrocyte under "shear stressl" force. Erythrocyte deformability has been described in a number of situations like hereditary or autoimmune hemolytic anemia. In

    Full Text Available INTRODUCTION: Anemia is defined as haemoglobin level in the blood below the lower extreme of the normal range for the age and sex of the individual. According to WHO, in developing countries the prevalence of anemia among pregnant women averages 60%, ranging between 35 to 100% among different regions of the world. A hemoglobin concentration below 11.0g/dl or packed cell volume (PCV of less than 33.0% is regarded as anemia during pregnancy by the WHO. It occurs in 40 - 80% of the pregnant women. Iron and folic acid defici encies, malaria, intestinal parasitic infections and hemoglobinopathies are the principal causes of anemia in pregnancy. Predisposing factors include young age, grand multiparity, low socioeconomic status, illiteracy, ignorance and short intervals of pregn ancy. AIM AND OBJECTIVES: 1. To study various patterns of anemia in pregnant women having haemoglobin level < 11 gm%. 2. To determine the most common pattern of anemia in pregnancy based on red cell morphology. MATERIALS AND METHODS: This study is a prospe ctive study over a period of one year from September 2014 to August 2015 in the department of pathology, Andhra medical college, Visakhapatnam . The study was conducted on 120 pregnant women whose haemoglobin level is < 11 gm/dl. All the haemotological parameters & peripheral blood smear stained by Leishman’s stain were evaluated. Complete clinical & obstetric history was recorded. Socioeconomic status was also noted. RESULTS: Out of 120 cases of anemia, we found 47 patie nts (39.1% having dimorphic anemia, 36(30% – microcytic hypochromic anemia, 23(19.1% - normocytic hypochromic anemia, 11(9.16% - sickle cell anemia and 1(0.83% case of pancytopenia.

    Personal experience is outlined with a preparative regimen consisting of total nodal irradiation (TNI) and cyclophosphamide in patients with severe aplastic anemia undergoing bone marrow transplantation (BMT). Nine patients (median age 23) previously having blood transfusions received BMT at the BMT Center in Pesaro. All patients were prepared for transplantation with cyclophosphamide 50 mg/kg/day (day -6, -5, -4, -3), and 7,5 Gy total nodal irradiation day -1, with a dose rate of 26 cGy/m. Six out of eight evaluable transplanted patients are still surviving 3 to 23 months with a median follow-up of 16,5 months. This preoperative regimen is extremely effective in decreasing rejection following transplantation for severe aplastic anemia. Future investigation must be aimed at the elimination of graft-versus-host-disease and control of fatal infections

    2014-01-01

    Fanconi anemia (FA) is a rare autosomal recessive cancer-prone inherited bone marrow failure syndrome, due to mutations in 16 genes, whose protein products collaborate in a DNA repair pathway. The major complications are aplastic anemia, acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and specific solid tumors. A severe subset, due to mutations in FANCD1/BRCA2, has a cumulative incidence of cancer of 97% by age 7 years; the cancers are AML, brain tumors, and Wilms tumor; several patients have multiple events. Patients with the other genotypes (FANCA through FANCQ) have cumulative risks of more than 50% of marrow failure, 20% of AML, and 30% of solid tumors (usually head and neck or gynecologic squamous cell carcinoma), by age 40, and they too are at risk of multiple adverse events. Hematopoietic stem cell transplant may cure AML and MDS, and preemptive transplant may be appropriate, but its use is a complicated decision. Published by Elsevier Ltd.

    Full Text Available Sickle cell anemia is an inherited hemoglobin disorder characterized by substitution of glutamic acid by valine at the sixth position of the beta globin chain. The sequence of events leads to pain crisis. Ischemia of the tissues resulting from decreased blood flow is believed to occur in pain crisis. Repeated or prolonged sickling causes red cell death in the form of hemolytic anemia. The majority of hospital admissions are due to painful crisis. These patients are at increased risk for both osteomyelitis and infarction of the long bones. Magnetic resonance imaging has been shown to be helpful in the diagnosis of early osteomyelitis and its differentiation from infarction in sickle cell disease patients with acute bone crisis. Others findings include dactylitis, medullary infarcts, diploic space widening, fish mouth vertebrae, and avascular necrosis. We present a case series on the various musculoskeletal manifestations of sickle cell disease.

    Background: Anemia in women of reproductive age (WRA) (age range: 15-49 y) remains a public health problem globally, and reducing anemia in women by 50% by 2025 is a goal of the World Health Assembly. Objective: We assessed the associations between anemia and multiple proximal risk factors (e.g., iron and vitamin A deficiencies, inflammation, malaria, and body mass index) and distal risk factors (e.g., education status, household sanitation and hygiene, and urban or rural residence) in nonpregnant WRA. Design: Cross-sectional, nationally representative data from 10 surveys ( n = 27,018) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project were analyzed individually and pooled by the infection burden and risk in the country. We examined the severity of anemia and measured the bivariate associations between anemia and factors at the country level and by infection burden, which we classified with the use of the national prevalences of malaria, HIV, schistosomiasis, sanitation, and water-quality indicators. Pooled multivariate logistic regression models were constructed for each infection-burden category to identify independent determinants of anemia (hemoglobin concertation <120 g/L). Results: Anemia prevalence was ∼40% in countries with a high infection burden and 12% and 7% in countries with moderate and low infection burdens, respectively. Iron deficiency was consistently associated with anemia in multivariate models, but the proportion of anemic women who were iron deficient was considerably lower in the high-infection group (35%) than in the moderate- and low-infection groups (65% and 71%, respectively). In the multivariate analysis, inflammation, vitamin A insufficiency, socioeconomic status, and age were also significantly associated with anemia, but malaria and vitamin B-12 and folate deficiencies were not. Conclusions: The contribution of iron deficiency to anemia varies according to a country's infection

Prevalence of anemia was 9.9% when HGB < 11.5g/dl was used, and 25.4% when the cut-off point was HGB < 12.0g/dl. Growth retardation was detected in 6.2% of children according to H/A, 4.0% for W/A, and 3.0% for W/H. There was no statistically significant association between the variables in the study. These findings confirm results of previous surveys where prevalence of anemia was much higher than that of growth retardation. The severe consequences of anemia in this age group justify the implementation of broad public policies to overcome this nutritional deficiency.

    Aplastic anemia is a syndrome in which hematopoietic stem cells are decreased and bone marrow hypoplasia and pancytopenia are observed; it is considered as a T cell-mediated autoimmune disease. Recently, it has been reported that gene mutations suggestive of clonal hematopoiesis are detected in approximately one third of the patients with aplastic anemia. Among treatment approaches other than hematopoietic stem cell transplantation, immunosuppressive therapy with antithymocyte globulin (ATG) plus cyclosporin is a basic approach, although it has been shown that eltrombopag, a thrombopoietin receptor agonist, is effective and that the recovery of hematopoiesis in three blood lineage is observed in some patients. Studies on the optimum dose of ATG are in progress. Regarding hematopoietic stem cell transplantation for aplastic anemia, regimens are being designed in which cyclophosphamide as a pretreatment is reduced and fludarabine is instead used in combination for the reduction of cardiotoxicity. Because HLA haploidentical transplantation has been developed and its reports are increasing for patients who cannot find appropriate donors, transplantation may be possible in patients who had previously given up on it.

    Many validated instruments exist for determining the impact of chemotherapy-induced anemia and related fatigue on patient quality of life, but few studies analyze how healthcare providers actually discuss these subjects with patients. The authors share their study results on patterns of communication between participating patients and their physicians and allied health professionals. Letters of invitation were mailed to over 1,000 community-based oncologists, 15 of whom met the criteria and agreed to participate in this study on a first-enrolled basis until sufficient participation was ensured. In total, 36 of their patients were audio- and/or video-recorded during their regularly scheduled visits. Post-visit interviews were conducted separately with patients and participating healthcare professionals. Interviews were transcribed and analyzed using sociolinguistic techniques. Although 52% of visit time was spent discussing side effects and symptoms, most discussions of anemia and fatigue lacked specificity necessary to determine their true impact on patients' lives. Physician inquiries regarding fatigue also tended to be too brief to elicit patients' chief concerns. Vocabulary used to discuss anemia and related fatigue was variable and imprecise, and no fatigue assessment instrument was used or referenced in any visit. Community-based oncologists are encouraged to modify their vocabulary and consider incorporating a validated fatigue instrument, either within or before the consultation, to improve the quality of such communication.

    Full Text Available O objetivo deste ensaio é refletir sobre o significado social de um crescente interesse pela anemia falciforme e outras doenças associadas ao corpo negro no Brasil. Investigarei a rede discursiva que se formou em torno da doença no contexto social da sua produção. Começo resumindo a analise feita do antropólogo Melbourne Tapper, do programa de combate à Anemia Falciforme nos Estados Unidos nos anos 70, logo após as vitórias dos negros na luta pelos direitos civis. Tapper (1999 argumenta que uma das conseqüências dessa política foi a criação de uma comunidade negra cidadã e responsável. O Programa de Anemia Falciforme, desenvolvido pelo governo brasileiro com participação de ativistas negros a partir da década de 1990, também contribui para a formação e de uma "comunidade negra responsável". O argumento do artigo é que a anemia falciforme torna-se muito mais que uma doença a ser erradicada. O discurso em torno dela é um poderoso elemento no processo de naturalização da "raça negra" (e, por oposição lógica e política, da "raça branca" num país que se imaginava como biológica e culturalmente híbrido.This essay reflects on the social significance of growing interest in sickle cell anemia and other illnesses associated with the black body in Brazil. I explore the discursive network that has taken shape around the disease within the social context of its production. I first summarize anthropologist Melbourne Tapper's analysis of the United States program to fight sickle cell anemia in the 1970s, shortly after blacks attained victories in the civil rights movement. Tapper (1999 argues that one of the consequences of this policy was the creation of a responsible black citizenry. In the late 1990s, the Brazilian government developed a program (Programa de Anemia Falciforme that counted on the heavy participation of black activists and that also contributed to the formation of a "responsible black community.

    Fanconi anemia is a rare genetic disorder resulting in a loss of function of the Fanconi anemia-related DNA repair pathway. Individuals with Fanconi anemia are predisposed to some cancers, including oropharyngeal and gynecologic cancers, with known associations with human papillomavirus (HPV) in the general population. As individuals with Fanconi anemia respond poorly to chemotherapy and radiation, prevention of cancer is critical. To determine whether individuals with Fanconi anemia are particularly susceptible to oral HPV infection, we analyzed survey-based risk factor data and tested DNA isolated from oral rinses from 126 individuals with Fanconi anemia and 162 unaffected first-degree family members for 37 HPV types. Fourteen individuals (11.1%) with Fanconi anemia tested positive, significantly more (P = 0.003) than family members (2.5%). While HPV prevalence was even higher for sexually active individuals with Fanconi anemia (17.7% vs. 2.4% in family; P = 0.003), HPV positivity also tended to be higher in the sexually inactive (8.7% in Fanconi anemia vs. 2.9% in siblings). Indeed, having Fanconi anemia increased HPV positivity 4.9-fold (95% CI, 1.6-15.4) considering age and sexual experience, but did not differ by other potential risk factors. Our studies suggest that oral HPV is more common in individuals with Fanconi anemia. It will be essential to continue to explore associations between risk factors and immune dysfunction on HPV incidence and persistence over time. HPV vaccination should be emphasized in those with Fanconi anemia as a first step to prevent oropharyngeal cancers, although additional studies are needed to determine whether the level of protection it offers in this population is adequate. ©2015 American Association for Cancer Research.

    In Latin America and the Caribbean, anemia has been a public health problem that affects mainly women of childbearing age and children under 6 years of age. However, the current prevalence of anemia in this region is unknown. To examine the latest available prevalence data on anemia in Latin America and the Caribbean. A systematic review was conducted in 2011 and updated in 2014. Studies determining the prevalence of anemia conducted in apparently healthy populations with national or regional representativeness were included in the review. The lowest prevalence rates of anemia among children under 6 years of age were found in Chile (4.0%), Costa Rica (4.0%), Argentina (7.6%), and Mexico (19.9%). In Nicaragua, Brazil, Ecuador, El Panama, and Honduras, anemia was a moderate public health problem, with prevalence ranging Salvador, Cuba, Colombia, the Dominican Republic, Peru, from 20.1% to 37.3%. Anemia was a severe public health problem in Guatemala, Haiti, and Bolivia. The prevalence of anemia among women of childbearing age was lowest in Chile (5.1%). In Colombia, El Salvador, Costa Rica, Nicaragua, Ecuador, Mexico, Peru, Honduras, and Argentina, anemia was a mild public health problem, with prevalence ranging from 7.6% to 18.7%. In Guatemala, Brazil, the Dominican Republic, and Bolivia, anemia was a moderate public health problem, with prevalence ranging from 21.4% to 38.3%. Panama and Haiti had the highest reported prevalence rates (40.0% and 45.5%, respectively), and anemia was considered a severe public health problem in those countries. Anemia remains a public health problem in children under 6 years of age and women of childbearing age in most Latin America and Caribbean countries for which data are available.

    Fanconi anemia is characterized by hypersensitivity to DNA interstrand crosslinks (ICLs) and susceptibility to tumor formation. Despite the identification of numerous Fanconi anemia (FANC) genes, the mechanism by which proteins encoded by these genes protect a cell from DNA interstrand crosslinks remains unclear. The recent discovery of two DNA helicases that, when defective, cause Fanconi anemia tips the balance in favor of the direct involvement of the FANC proteins in DNA repair and the bypass of DNA lesions.
