Although its etiology is understood and intervention at low cost is available, the problem persists. The present review begins with a general estimate of the dimensions of the problem. It suggests the necessary elements for the design, implementation, and measurement of the impact of iron supplementing and fortification as the most effective forms to intervene and diminish iron deficiency anemia. Several preliminary steps are proposed previous to the preparation of a project and several recomendations are made to be included in a project for fortification and iron supplementing. A list of complementary activities offered by PAHO/WHO as part of the package of technical cooperation is included.

    La anemia es un problema de salud mundial que afecta tanto a los países desarrollados como a aquellos en desarrollo. Sus causas pueden ser multifactoriales y frecuentemente pueden coexisitir varias de ellas; la principal es la baja ingestión de alimentos con fuentes adecuadas de hierro, tanto en cantidad como en calidad. 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 p...

    Full Text Available Inherited erythrocytic pyruvate kinase (PK deficiency is an autosomal recessive hemolytic disorder described in dogs and cats. Pyruvate kinase is one of two key-regulatory enzymes in the anaerobic glycolytic pathway, and its deficiency causes premature destruction of the ATP-depleted red cells. This case study reports the clinical and laboratory findings in a West Highland White Terrier (WHWT dog with a life-long history of weakness and exercise intolerance from Brazil. The dog was found to have persistently profound pallor, a highly regenerative hemolytic anemia and osteosclerosis. PK deficiency was confirmed by a breed-specific DNA test for the previously described 6 bp insertion at 3' end of exon 10 in red blood cell (RBC R- PK gene sequence. The dog was euthanized at 20 months of age due to the deterioration of its clinical condition including anemia and blood incompatibility. Other PK-deficient WHWTs have lived as long as 9 years. Hereditary red cell defects are important differential diagnoses for chronic hemolytic anemias in younger animals after excluding immune-mediated and infectious causes. Furthermore, purebred dogs for which DNA tests for hereditary diseases are available should be screened prior to breeding in order to limit the spread of the mutant allele and to avoid future production of PK-deficient animals.La deficiencia de piruvato quinasa (PK es un desorden hemolítico autosómico recesivo descrito en perros y gatos. La piruvato quinasa es una de las enzimas regulatorias esenciales de la glicólisis anaeróbica, la deficiencia de esta enzima causa una destrucción prematura de los eritrocitos. El presente es un estudio de caso y relata los hallazgos clínicos y paraclínicos en un perro brasileño de la raza West Highland White Terrier (WHWT con historia de debilidad e intolerancia al ejercicio. El paciente presentaba mucosas pálidas, anemia hemolítica bastante regenerativa y osteoclerosis. La deficiencia de PK fue

    Full Text Available La deficiencia de hierro es el trastorno hematológico más frecuente alrededor del mundo y afecta a 2,000 millones de personas aproximadamente, de los cuales 77 millones viven en América Latina y el Caribe. La deficiencia de hierro tiene un espectro que va desde la reducción y agotamiento de las reservas de hierro, hasta la reducción de las células rojas y de la concentración de hemoglobina. En consecuencia, hay deficiencias de hierro sin anemia. Los niños son uno de los grupos más vulnerables a esta deficiencia, debido al rápido período de crecimiento cerebral, en especial durante los dos primeros años de vida. El hierro es uno de los principales sustratos que soportan y permiten el desarrollo y la actividad metabólica de múltiples procesos a nivel cerebral, entre los cuales se encuentra el proceso de mielinización. Una insuficiente disponibilidad de hierro en un período de alta incorporación de éste en el tejido cerebral, que coincide con el período de mielinización del tejido nervioso, puede proveer una base fisiológica para explicar los efectos conductuales observados cuando hay deficiencias del micronutriente. De la misma manera, la deficiencia de hierro afecta la regulación y la conducción de neurotransmisores como la serotonina, la dopamina y GABA. La alteración de los receptores y transportadores de dopamina, compromete en los infantes las respuestas afectivas y el funcionamiento cognoscitivo, y los de los receptores GABA, la coordinación de patrones de movimiento y memoria. La importancia consiste que cuando ocurre un déficit de hierro cerebral en etapas tempranas, los daños ocurridos persisten en la etapa adulta, más allá de la recuperación de la anemia durante los primeros meses de vida. Estas alteraciones cerebrales se reflejan a largo plazo en un retraso del desarrollo mental y físico de los niños que han tenido anemia, y como consecuencia un menor desempeño escolar, con altos niveles de repetici

La alta frecuencia de donantes de sangre con deficiencia de hierro encontrada en este estudio sugiere la necesidad de pruebas de laboratorio más exactas. La determinación de hemoglobina únicamente no es suficiente para encontrar y excluir donantes de sangre con deficiencia de hierro sin anemia y los ajustes hacia niveles más altos de los criterios de aceptación de hemoglobina no contribuye a mejorar la situación comprometiendo el suministro de sangre, al pasar la exclusión de donantes por hemoglobina baja de 9% en la actualidad a 44.6%.

    Full Text Available El objetivo de este estudio fue conocer y comprender la orientación sexual proveniente de madres de hijos portadores de deficiencia visual. Bajo la perspectiva fenomenológica, se analizan veinte discursos de madres de deficientes visuales. El recorrido por todos los discursos permite conocer que la desinformación sobre la sexualidad en general, impide el diálogo entre madre e hijo(a. Tales recorridos evidencian igualmente, que la represión sexual fundamenta los estigmas y los preconceptos en la educación sexual de los deficientes visuales. The objective of this study is to analyze and understand the sexual orientation given by mothers to sons and daughters with visual deficiencies. From a phenomenological perspective the narratives of twenty mothers of visual defficients are analyzed. The convergences of these conversations make clear that disinformation about sexuality in general impedes dialogues between mothers and offspring. Evidence was obtained showing that sexual repression stems from stigmas and preconcepts about sexual education of persons with visual defficiencies.

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.

El presente trabajo tuvo como objetivos describir los aspectos mas importantes del metabolismo de hierro en el hombre y especialmente en el cerebro, los mecanismos fisiológicos por los cuales la deficiencia de hierro puede causar afectaciones en el sistema nervioso central (SNC de niños y adolescentes, algunos de los estudios que demuestran la relación entre las afectaciones en el desarrollo neural y la deficiencia de hierro, así como las principales estrategias de nuestro país para combatir este trastorno nutricional. La deficiencia de hierro ocasiona hipomielinización, lo cual origina neuronas deficientes. Por otra parte está asociada con la alteración en varios procesos metabólicos que impartan en el adecuado funcionamiento cerebral, como son el transporte de electrones y la síntesis de neurotransmisores. Numerosos estudios realizados en bebes, niños en edad escolar y adolescentes evidencian el retardo en el aprendizaje de niños anémicos con respecto a los no anémicos, así como afectaciones en el sistema visual y auditivo. En nuestro país se utilizan las sales ferrosas y el biopreparado hierro ¿ proteína, Trofín para la prevención y tratamiento de la deficiencia de hierro, sin embargo las estrategias para combatir esta deficiencia, aún son insuficientes.

    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.

    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

    Full Text Available La deficiencia de ácido fólico es la causa más frecuente de anemia en nuestro medio, después del síndrome anémico de origen ferropénico. Los folatos son componentes esenciales de la dieta humana y animal. En los alimentos el ácido fólico se encuentran principalmente en forma de poliglutamatos, formas que luego son hidrolizadas en el intestino delgado a nivel de yeyuno proximal. Es importante definir con exactitud el defecto vitamínico causante de la anemia megaloblástica, puesto que, la administración de vitamina B12 a pacientes con deficiencia de folatos puede corregir parcialmente las alteraciones megaloblásticas, sin embargo, la administración de ácido fólico a pacientes con deficiencia de cobalamina induce mejoría hematológica, pero empeora el cuadro neurológico. Las principales causas de anemia por deficiencia de folatos son un aporte dietético insuficiente, un aumento de los requerimientos, defectos de su absorción o interacción con fármacos. Los folatos, pueden verse perjudicados por la sensibilidad a la luz y a las altas temperaturas así como por su alta afinidad por el agua, lo que facilita su eliminación por lavado o cocción.Folic acid deficiency is the second most common cause of anemia in our environment, after anemia secondary to iron deficiency. Folates are essential components of human and animal diet. Folic acid is mainly in poliglutamate form, and it is hydrolyzed in the proximal jejunum. It is important to identify adequately the exact vitamin deficiency that causes megaloblastic anemia, because vitamin B12 administration in folate deficiency may correct partially megaloblasticalterations, but administration of folic acid in cobalamin deficient patients improves haematological parameters but deteriorates the neurological syndrome. Main causes of anemia secondary to folate deficiency are inadequate dietetic administration, increased requirements, impaired absorption and pharmacologic interactions

  20. A hepcidina como parâmetro bioquímico na avaliação da anemia por deficiência de ferro Hepcidin as a biochemical parameter for the assessment of iron deficiency anemia

    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.

La dieta es de gran importancia en la anemia, sin embargo, ningún alimento contiene concentraciones suficientes de hierro para poder constituir un remedio práctico en los estados de carencia del mismo, por lo que el tratamiento debe realizarse por vía oral con preparados a poder ser a base de sulfato ferroso para asegurar una mejor absorción. Se recomienda una dosis inicial de 150-200 mg. de hierro elemental al día, repartido en tres tomas (3-5 mg/kg/día en niños.Anemia secondary to iron deficiency is the most frequent anaemia in our environment, the first cause of consultation in Haematology and the most common nutritional problem. It is characterized by a diminution or absence of iron deposits. The ultimate test that confirms the diagnosis of anaemia secondary to iron deficiency is a low serum level of ferritin, which indicates iron depletion. Other parameters do not allow to distinguish iron deficiency anaemia from other chronic derangements. Diet is of utmost importance in anaemia. There is not a single food product with sufficient concentration of iron capable of restoring iron deficiency situations. Therefore, treatment of iron deficiency must be made orally with iron preparates, mainly in the form of iron sulphate in order to guarantee a better absorption. The initial recommended doses are 150-200 mg of elemental iron per day split in three ingestions (in children 3-5 mg/Kg/day.

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.

    Full Text Available Resumo: O controle das endoparasitoses gastrintestinais em pequenos ruminantes tem sido tradicionalmente realizado por meio do uso indiscriminado dos anti-helmínticos, porém essa prática tem resultado em grande pressão de seleção de parasitas resistentes. Métodos seletivos (ex: FAMACHA/FMC e contagem de ovos nas fezes/OPG e que apresentem boa sensibilidade para identificar os animais que necessitam receber o tratamento químico são importantes alternativas aos métodos tradicionais. O objetivo desse trabalho foi determinar a sensibilidade e a especificidade do método FMC, usado para detectar anemia causada por Haemonchus contortus em ovinos da raça Suffolk, em duas categorias de alta suscetibilidade; cordeiros lactentes e ovelhas durante a fase de lactação. A conjuntiva ocular de 42 cordeiros lactentes e 35 ovelhas em lactação foi avaliada usando o método FMC, em intervalos de 14 dias, durante cinco meses. O hematócrito (Ht foi utilizado como padrão-ouro para avaliação clínica de anemia dos animais. Para o cálculo de sensibilidade e especificidade, diferentes critérios foram utilizados: animais classificados como 4 e 5 ou 3, 4 e 5 e anêmicos pelo Ht (teste positivo; animais classificados como 1, 2 e 3 ou 1 e 2 e não anêmicos pelo Ht (teste negativo. Três valores de corte para Ht (≤22%, ≤19% ou ≤15% foram utilizados para confirmar a anemia. Entre os gêneros observados nas coproculturas, H. contortus (61,5% e Ostertagiasp (21,3% foram os mais prevalentes. Em ambas as categorias, a inclusão do FMC 3 como teste positivo, elevou a sensibilidade mas reduziu a especificidade do método. Quando o FMC 3 foi considerado anêmico, o percentual de falsos negativos foi próximo a zero, no entanto, houve aumento no número de tratamentos aplicados em animais não anêmicos (falso positivo. Durante as avaliações, a maior parte dos cordeiros (73% e das ovelhas (53% permaneceu nas categorias de FMC 1 e 2. Apenas 5% dos

Foram estudadas seis cabras, adultas, com parâmetros eritrocitários indicativos e anemia e manifestações de doença respiratória (tosse, espirros e secreção nasal. O grupo controle foi composto por seis cabras adultas, sadias. As cabras de ambos os grupos após serem submetidos à avaliação clínica receberam dose similar (0,5g de hidróxido férrico em complexo dextrânico, por via intramuscular. Amostras de sangue colhidas com EDTA, antes da aplicação do ferro e 48 horas depois foram utilizadas para determinação da concentração de substâncias reativas ao ácido tiobarbitúrico (TBARS. Nas cabras doentes antes da aplicação do ferro os valores de TBARS foram equivalentes aos valores mensurados nos controles antes e após a aplicação do ferro (p>0,05. Os valores mensurados nas cabras doentes foram muito mais elevados (p<0,001 no mesmo grupo de animais depois da aplicação do ferro e nos controles antes e após a aplicação. A aplicação do ferro agravou a condição clinica dos animais com doença respiratória, sendo evidenciada uma condição de toxidade refletida pelo estresse oxidativo.

    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

    Full Text Available OBJETIVOS: determinar os motivos de encaminhamento e diagnósticos de crianças com anemia para serviço especializado. MÉTODOS: coorte histórico e concorrente de crianças com anemia encaminhadas ao Serviço de Hematologia do Hospital das Clínicas da Universidade Federal de Minas Gerais, Belo Horizonte, Minas Gerais, Brasil, entre maio de 1999 e dezembro de 2001. RESULTADOS: foram avaliadas 153 crianças menores de 16 anos, sendo 83% procedentes de Centros de Saúde. Aproximadamente um terço das crianças não recebeu qualquer terapêutica no serviço de origem. Cento e onze (71,3% tiveram diagnóstico de anemia ferropriva. Treze crianças (8,6% tiveram diagnóstico de talassemia minor; outras treze crianças apresentaram outros diagnósticos de anemias e 11,5% das crianças não apresentavam anemia. Os valores médios de hemoglobina na abordagem pelo hematologista foram significativamente maiores que os dos serviços de origem (9,7±1,9 vs. 8,9±2,0; p=0,001. Somente 16,2% crianças não responderam ao primeiro tratamento com sais de ferro oral, sendo o sulfato ferroso o principal medicamento prescrito (79,3%. CONCLUSÕES: A deficiência de ferro foi a principal etiologia das crianças encaminhadas por motivo de anemia para serviço especializado. Encaminhamentos desnecessários de indivíduos com anemia ferropriva para serviços especializados representam prejuízo aos pacientes e ônus excedente para o sistema de saúde.OBJECTIVES: to determine the reasons for diagnosis of anemia among children and referral to specialized services.

    Full Text Available Introducción: La malaria, la anemia y la parasitosis intestinal coexisten y constituyen problemas de salud pública en Colombia. Datos disponibles en la literatura biomédica llevan a pensar que estos problemas no son aislados sino que están interrelacionados. Por otra parte, los suplementos de retinol han sido efectivos para reducir la mortalidad infantil, con disminución de complicaciones en niños palúdicos, posiblemente por efectos del retinol sobre la función inmune, desviando la respuesta de citocinas hacia un patrón TH2, que también protege de desarrollar anemia grave. Esta revisión tiene como objetivo describir parte de las relaciones vistas en la literatura biomédica mundial, entre retinol y malaria, retinol y anemia, retinol, malaria y parasitosis intestinal, anemia y malaria y mostrar la mediación de estas interrelaciones por el patrón de citocinas TH1/TH2 en sujetos con malaria.Metodología: Se consultaron las siguientes bases de literatura biomédica: Medline, Lilacs, Spingerlik, Md Consultant, Web of Science, Ovid, Scient Direct, Ebsco y Cochrane. También se buscó información para documentar la prevalencia de desnutrición, deficiencia subclínica de retinol, anemia y malaria en niños colombianos, lo mismo que sobre el papel antinfeccioso del retinol.Resultados: Existe asociación entre parasitosis intestinal y malaria; algunos estudios indican que los helmintos predisponen a contraer malaria en niños. De otro lado, los parásitos mencionados, también se han relacionado con anemia y bajas concentraciones plasmáticas de retinol, que a la vez se asocian con malaria. Sin embargo, no se encontró información que relacione simultáneamente todos estos tópicos y que muestre la respuesta de citocinas TH1/TH2 como la articulación de todos ellos.Conclusiones: Aclarar las múltiples interacciones entre malaria, anemia, parasitosis intestinal y deficiencia subclínica de retinol, teniendo como eje central la respuesta de

No hubo diferencias significativas entre los grupos esteroide y no esteroide dependientes, ni entre los asmáticos alérgicos e intrínsecos, ni entre los con infección recurrente o sin ella. predominó la deficiencia de IgG1; en total el 46.7% de los pacientes tenían deficiencia aislada o combinada de IgG1, el 31.1% de IgG2, el 24.4% de IgG3 y el 17.8% de Igd4. La alta incidencia de deficiencia de sub clases podría deberse a la acción de los esteroides o a una alteración en la regulación de la síntesis de Igs producida por un defecto Inmune primario. Esta deficiencia sería la responsable del comportamiento agresivo de la enfermedad.

    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 Anemia é uma complicação comum em pacientes com mieloma múltiplo (MM e ocorre em mais de 2/3 dos pacientes. Anemia de doença crônica, deficiência de eritropoetina (EPO devido à insuficiência renal e efeito mielossupressivo da quimioterapia são os principais mecanismos patofisiológicos que contribuem para o desenvolvimento de anemia no MM. Nos pacientes que obtêm remissão completa com tratamento quimioterápico, anemia usualmente se normaliza. Nos pacientes que não respondem ou apresentam recaída do mieloma, anemia freqüentemente persiste. As opções de tratamento dos pacientes anêmicos com MM incluem transfusões de hemácias e EPO recombinante humana. Essa proteína é biologicamente equivalente à EPO endógena e sua administração promove aumento dos valores de hemoglobina por tempo mais prolongado sem os riscos das transfusões de sangue. Vários estudos têm relatado melhora significante da eritropoese, redução da necessidade transfusional e melhora da qualidade de vida com o uso da EPO como tratamento a longo prazo da anemia associada ao mieloma. Nesse artigo, propomos o tratamento da anemia do MM baseado nas recomendações propostas pela Sociedade Americana de Hematologia (ASH em conjunto com a Sociedade Americana de Oncologia Clínica (ASCO, pela Organização Européia para Pesquisa e Tratamento do Câncer (EORTC, pelo IMF (Internacional Myeloma Foundation e pelo NCCN (National Comprehensive Cancer Network.Anemia is a common complication in patients with multiple myeloma (MM occurring in more than two thirds of all patients. Anemia of chronic diseases, erythropoietin (EPO deficiency due to renal impairment and the myelosuppressive effect of chemotherapy are the most important pathophysiological mechanisms contributing to the development of anemia in MM. In patients who achieve complete remission after chemotherapy, anemia usually normalizes. Non-responders and relapsing myeloma patients often continue to suffer

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

    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.

    Full Text Available Se presenta el caso de un paciente masculino con neutropenia crónica e infección por el virus de inmunodeficiencia humana, con una revisión de los posibles mecanismos patogénicos. Las alteraciones hematológicas como anemia, trombocitopenia y leucopenia se presentan asociadas con frecuencia a la infección aguda por el virus de inmunodeficiencia humana. Al establecer la terapia antirretroviral y disminuir la actividad del virus, estas alteraciones tienden a mejorar. Sin embargo, algunos fármacos antirretrovirales, como la zidovudina, poseen toxicidad medular y pueden producir o empeorar las alteraciones hematológicas en estos pacientes, lo cual lleva a cambios en los esquemas de tratamiento. Los citotóxicos y antimetabolitos empleados en el tratamiento de neoplasias asociadas tienen conocida actividad depresora sobre la médula ósea. Algunos antimicrobianos utilizados en la profilaxis de infecciones poseen también toxicidad hematológica conocida, como el trimetoprim-sulfametoxazol, por lo que deben ser utilizados con precaución en pacientes con infección por el virus de inmunodeficiencia humana. Por otro lado, se plantean mecanismos alternativos que causan neutropenia en estos pacientes, como la formación de anticuerpos antineutrófilos, daño primario del progenitor granulocítico, por desbalance en la producción de neutrófilos, por anticuerpos contra la glicoproteína gp120 de la cápside viral del VIH, y deficiencias vitamínicas. En el caso del paciente neutropénico febril, en quien se sospecha infección bacteriana grave, se pueden utilizar los factores estimulantes de las colonias de granulocitos para aumentar los conteos absolutos de neutrófilos y mejorar la recuperación clínica.

    The laboratory evaluation of anemia begins with a complete blood count and reticulocyte count. The anemia is then categorized as microcytic, macrocytic or normocytic, with or without reticulocytosis. Examination of the peripheral smear and a small number of specific tests confirm the diagnosis. The serum iron level, total iron-binding capacity, serum ferritin level and hemoglobin electrophoresis generally separate the microcytic anemias.

    Anemia is a common problem in primary care. Classification based on mean cell volume narrows the differential diagnosis and directs testing. A marked macrocytosis is characteristic of vitamin B12 and folate deficiencies, certain medications, and primary bone marrow disorders. The three most common causes of microcytic anemia are iron deficiency, thalassemia trait, and anemia of inflammation. Additional laboratory testing is required for diagnosis. Determination of the rate of development of anemia and examination of a blood smear may provide diagnostic clues to guide more specialized testing. Diagnosis of iron, vitamin B12, or folate deficiency mandates determination of the underlying cause. PMID:27212091

    Macrocytic anemia, defined as a mean cell volume (MCV) ≥100 fL in adults, has a narrow differential diagnosis that requires evaluation of the peripheral blood smear as well as additional laboratory testing taken in conjunction with clinical information that includes patient history and physical examination findings. This review is an update on the approach to a patient with macrocytic anemia with attention paid to the differentiation of megaloblastic and non-megaloblastic macrocytic anemias.

  16. Mouse models of Fanconi anemia

    International Nuclear Information System (INIS)

    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.

    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.

  18. Megaloblastic anemia in Japan

    Full Text Available Since 1903, 744 cases of megaloblastic anemia have been reported in Japan: 490 cases of pernicious anemia; 95 cases associated with pregnancy; 66 cases after gastrectomy; 22 cases of megaloblastic anemia of infants; 21 cases of folic acid deficiency other than pregnancy and 19 cases of vitamin B12 malabsorption after ileal resection. It is generally agreed among hematologists in Japan that pernicious anemia is relatively rare, as in other Asian countries. The diagnosis of pernicious anemia in Japan is usually made by stained marrow films, radioisotopic assay of serum vitamin B12, Schilling test and good response to vitamin B12 therapy. Serum folate level, intrinsic factor or its antibody, methylmalonic acid excretion, formiminoglutamic acid excretion and deoxyuridine suppression test are performed only at a small number of laboratories. The drugs of choice are hydroxocobalamin, deoxyadenosylcobalamin and methylcobalamin. Cyanocobalamin has nearly disappeared from commercial sources in Japan. Vitamin B12 administration is common in patients with neurological disorders. Megaloblastic anemia due to folic acid deficiency is extremely rare in Japan. Low serum folate levels are frequently observed among patients receiving anticonvulsants or in pregnant women, but in such samples megaloblastic anemia is almost never detected. The folic acid content of hospital diets indicates that satisfactory amounts of folate are taken in Japan. The intake of folic acid from rice is well over the minimum daily requirement of folate. Other factors in folic acid deficiency, such as food taboos, severe alcoholism and malabsorption syndrome are not frequently found in Japanese. The inadequate intake of folate was the critical factor in most reported cases.

    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.

    2015-09-01

    Clinical assessment of tissue oxygenation is challenging. Anemia reflects a decreased oxygen carrying capacity of the blood and its significance in the perioperative setting relates largely to the associated risk of insufficient oxygen delivery and cellular hypoxia. Until meaningful clinical measures of tissue oxygenation are available in veterinary practice, clinicians must rely on evaluation of a patient's hemodynamic and ventilatory performance, along with biochemical and hemogasometric measurements. Blood transfusion is used commonly for treatment of perioperative anemia, and may improve tissue oxygenation by normalizing the rheologic properties of blood and enhancing perfusion, independent of increases in oxygen carrying capacity.

    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.

  17. Anemia of Chronic Liver Diseases

    International Nuclear Information System (INIS)

    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 T50 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.

    neurotransmisores y en la síntesis de ADN/ARN. Esta vitamina también puede ser un modulador de la expresión génica. Hoy en día, la deficiencia clínicamente evidente de vitamina B6 no es una afección habitual, al menos en la población general. Sin embargo, puede ocurrir una deficiencia subclínica no diagnosticada en algunos individuos, especialmente en los ancianos. Objetivo: esta revisión aporta una visión de conjunto completa sobre el metabolismo y las interacciones de la vitamina B6. Además, mostramos qué complicaciones y síntomas por deficiencia pueden ocurrir por la falta de vitamina B6 y las posibilidades de intervenciones de salud pública y de suplementos. Métodos: se buscó en la base de datos Medline (www.ncvi.nlm.nih.gov con los términos "vitamin B6", "pyridoxal", "cancer", "homocysteine", etc. Para una mayor comprensión, incluimos estudios con hallazgos iniciales de los años cuarenta, así como estudios recientes del año 2006. Se resumieron estos estudios y se compararon por capítulos diferentes. Resultados y Conclusión: de hecho, se ha propuesto que el estado sub-óptimo de vitamina B6 se asocia con ciertas enfermedades que afligen en especial a la población anciana: función cognitiva alterada, enfermedad de Alzheimer, cardiopatía y distintos tipos de cáncer. Algunos de estos problemas podrían relacionarse con concentraciones elevadas de homocisteína asociadas con una deficiencia de vitamina B6, pero también existe la evidencia de otros mecanismos independientes de la homocisteína por los que un estado sub-óptimo de vitamina B6 podría aumentar el riesgo de padecer estas enfermedades crónicas.

    Full Text Available Introducción: La vitamina D es esencial para la prevención de diversas enfermedades crónicas. Aunque se puede sintetizar a nivel cutáneo, esta fuente no es siempre suficiente para cubrir sus necesidades, por lo que el consumo de alimentos ricos en la misma, como el huevo, podría ser muy beneficioso en individuos que están en riesgo de presentar deficiencia. Objetivo: Estudiar la relación entre el estatus en vitamina D y el consumo diario de huevos en un colectivo de escolares. Metodología: Se incluyeron 564 escolares (9 a 12 años de la Comunidad de Madrid. La ingesta de alimentos, de energía y nutrientes (incluidos el huevo y la vitamina D, se determinó empleando un registro del consumo de alimentos durante 3 días. Se calculó el Índice de Masa Corporal a través del peso corporal y la talla. Se valoró el colesterol total, lipoproteínas, triglicéridos y vitamina D sérica. Resultados: El consumo medio de huevos fue de 32,7 ± 20,9 g/día (inferior a 0,5 huevo/día recomendados en el 36,3% de los escolares. Se dividió a los escolares en función de que tuvieran un consumo > o < 0,5 huevo/día (grupos SH e IH, respectivamente. La ingesta y los niveles séricos de vitamina D fueron significativamente superiores en el grupo SH que en el IH. Además, los primeros tuvieron menor riesgo de presentar deficiencia moderada de vitamina D (< 50 nmol/L (OR = 0,41 (0,19-0,88; p = 0,022. No se observaron diferencias significativas entre los grupos en relación con las cifras de colesterol total y triglicéridos. Conclusión: Es recomendable fomentar el consumo de al menos 0,5 huevo/día entre la población infantil debido a su alto contenido en vitamina D, lo que podría evitar la aparición de problemas de salud.

    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 de Doença Crônica (ADC é usualmente definida como a anemia que ocorre em distúrbios infecciosos crônicos, inflamatórios ou doenças neoplásicas, e é uma das síndromes clínicas mais comuns na prática clínica. Caracteristicamente, ADC corresponde à anemia normocrômica/normocítica, leve a moderada, e caracteriza-se por hipoferremia na presença de estoques adequados de ferro. Os três principais mecanismos patológicos envolvidos na ADC são: diminuição da sobrevida da hemácia, falha da medula óssea em aumentar a produção de glóbulos vermelhos para compensar o aumento da sua demanda, e distúrbio da mobilização do ferro de depósito do sistema mononuclear fagocitário. O papel central dos monócitos e dos macrófagos e o aumento da produção de citocinas mediadoras da resposta imune ou inflamatória, tais como: TNF alfa, INF gama e IL-1 estão implicados nos três processos envolvidos no desenvolvimento da ADC. O propósito desse artigo é revisar os recentes avanços no entendimento dos aspectos patofisiológico, diagnóstico e terapêutico desta síndrome.The anemia of chronic disease (ACD is usually defined as the anemia occurring in chronic infectious, inflammatory disorders, or neoplastic diseases, and is one of the most common syndromes in the clinical practice. Characteristically, ACD is a mild-to-moderate, normochromic/normocytic anemia, and is characterized by hypoferremia in the presence of adequate iron stores. The three principal pathologic mechanisms involved in ACD are: reduced erythrocyte survival, bone marrow failure to increase red blood cell production to compensate for the increase in its demand, and abnormal mobilization of reticuloendothelial iron stores. The central role of monocytes and macrophages, and the increased production of the cytokines that mediate the immune or inflammatory response, such as tumor necrosis factor, interleukin-1 and the interferons, are implicated in all three

    Background Sickle cell disease, the most common hereditary blood disease in the world, is the result of an atypical hemoglobin called S (Hb S) which, when homozygous (Hb SS) is the cause of sickle cell anemia. Changes of puberty, correlated with a delayed growth spurt, begin late in both male and female sickle cell anemia individuals with repercussions on sexuality and reproduction. The objectives of this exploratory and descriptive study were to characterize the development of sexuality in adults with sickle cell anemia by investigating the patient's perception of their sex life, as well as the information they had and needed on this subject. Methods Twenty male and female sickle cell anemia patients treated at the Hemocentro Regional de Uberaba (UFTM) with ages between 19 and 47 years old were enrolled. A socioeconomic questionnaire and a semi-structured interview on sexuality, reproduction and genetic counseling were applied. Results This study shows that the sickle cell anemia patients lacked information on sexuality especially about the risks of pregnancy and the possible inheritance of the disease by their children. Moreover, the sexual life of the patients was impaired due to pain as well as discrimination and negative feelings experienced in close relationships. Conclusion The health care of sickle cell anemia patients should take into account not only the clinical aspects of the disease, but also psychosocial aspects by providing counseling on sexuality, reproduction and genetics, in order to give this population the possibility of a better quality of life.

    1999-09-01

    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.

    Iron deficiency is not just anemia; it can be responsible for a long list of other manifestations. This topic is of great importance, especially in infancy and early childhood, for a variety of reasons. Firstly, iron need is maximum in this period. Secondly, diet in infancy is usually deficient in iron. Thirdly and most importantly, iron deficiency at this age can result in neurodevelopmental and cognitive deficits, which may not be reversible. Hypochromia and microcytosis in a complete blood count (CBC) makes iron deficiency anemia (IDA) most likely diagnosis. Absence of response to iron should make us look for other differential diagnosis like β thalassemia trait and anemia of chronic disease. Celiac disease is the most important cause of true IDA not responding to oral iron therapy. While oral ferrous sulphate is the cheapest and most effective therapy for IDA, simple nonpharmacological and pharmacological measures can go a long way in prevention of iron deficiency.

    Lower hemoglobin is associated with cognitive impairment and Alzheimer's disease (AD). Since brain iron homeostasis is perturbed in AD, we investigated whether this is peripherally reflected in the hematological and related blood chemistry values from the Australian Imaging Biomarker and Lifestyle (AIBL) study (a community-based, cross-sectional cohort comprising 768 healthy controls (HC), 133 participants with mild cognitive impairment (MCI) and 211 participants with AD). We found that individuals with AD had significantly lower hemoglobin, mean cell hemoglobin concentrations, packed cell volume and higher erythrocyte sedimentation rates (adjusted for age, gender, APOE-ɛ4 and site). In AD, plasma iron, transferrin, transferrin saturation and red cell folate levels exhibited a significant distortion of their customary relationship to hemoglobin levels. There was a strong association between anemia and AD (adjusted odds ratio (OR)=2.43, confidence interval (CI) (1.31, 4.54)). Moreover, AD emerged as a strong risk factor for anemia on step-down regression, even when controlling for all other available explanations for anemia (adjusted OR=3.41, 95% CI (1.68, 6.92)). These data indicated that AD is complicated by anemia, which may itself contribute to cognitive decline. PMID:24419041

    Biermer disease or pernicious anemia is an autoimmune atrophic gastritis characterized by the lack of secretion of gastric intrinsic factor. This leads to an insufficient absorption of vitamin B12 in the ileum. Clinical manifestations are mainly hematologic. Neuropsychiatric manifestations are known but are less frequent especially early in the disease. Inaugural neuropsychiatric arrays are rare and various thus making diagnosis difficult. In this article, we report through two clinical cases different neuropsychiatric manifestations revealing pernicious anemia. Mrs. C.O., aged 56, presented after surgery for gallstones, an acute psychiatric array associated with gait disorders. She had no history of neurological or psychiatric problems. The psychiatric interview revealed delirious syndrome, depressive symptoms and anxiety. Neurological examination noted a flaccid paraplegia with peripheral neuropathic syndrome and myoclonus in the upper limbs. At the full blood count, a macrocytosis (VGM: 112.2fl) without anemia was found. The level of vitamin B12 in the blood was low. Cerebro-spinal MRI was suggestive of a neuro-Biermer and showed hyper signal in the cervical cord on T2-weighted sagittal section. In axial section, hyper signal appears at the posterior columns in the form of V. There were no brain abnormalities. A sensorimotor axonal polyneuropathy was diagnosed. The patient received vitamin B12 intramuscularly for ten days associated with neuroleptic treatment. Mrs. R.M., aged 40, was brought to the psychiatry consultation for acute behavioral disorders progressively worsening over a month. An anxiety syndrome, depressive syndrome and delirious syndrome were identified. Neurological examination showed a posterior cordonal syndrome with quadripyramidal syndrome. Full blood count showed a macrocytic anemia. Serum B12 level was collapsed. Cerebro-spinal MRI was normal. She received vitamin B12 with clinical and biological improvement.

    Hemolytic anemias consist of corpuscular, immun-hemolytic and toxic hemolytic anemias. Within the group of corpuscular hemolytic anemias, except for the paroxysmal nocturnal hemoglobinuria (PNH), all symptoms are caused by underlying heredetiary disorders within the red blood cell membran (hereditary spherocytosis), deficiencies of red cell enzymes (G6PDH- and pyrovatkinase deficiency) or disorders in the hemoglobin molecule (thalassaemia and sickle cell disease). Immune-hemolytic anemias are acquired hemolytic anemias and hemolysis is caused by auto- or allo-antibodies which are directed against red blood cell antigens. They are classified as warm, cold, mixed type or drug-induced hemolytic anemia. Therapy consists of glucocorticoids and other immunsuppressive drugs. Pernicious anemia is the most important vitamin B12 deficiency disorder. Diagnosis relies on cobalamin deficiency and antibodies to intrinsic factor. The management should focus on a possibly life-long replacement treatment with cobalamin. PMID:26306021

    Full Text Available Se presenta el caso de un paciente masculino con neutropenia crónica e infección por el virus de inmunodeficiencia humana, con una revisión de los posibles mecanismos patogénicos. Las alteraciones hematológicas como anemia, trombocitopenia y leucopenia se presentan asociadas con frecuencia a la infección aguda por el virus de inmunodeficiencia humana. Al establecer la terapia antirretroviral y disminuir la actividad del virus, estas alteraciones tienden a mejorar. Sin embargo, algunos fármacos antirretrovirales, como la zidovudina, poseen toxicidad medular y pueden producir o empeorar las alteraciones hematológicas en estos pacientes, lo cual lleva a cambios en los esquemas de tratamiento. Los citotóxicos y antimetabolitos empleados en el tratamiento de neoplasias asociadas tienen conocida actividad depresora sobre la médula ósea. Algunos antimicrobianos utilizados en la profilaxis de infecciones poseen también toxicidad hematológica conocida, como el trimetoprim-sulfametoxazol, por lo que deben ser utilizados con precaución en pacientes con infección por el virus de inmunodeficiencia humana. Por otro lado, se plantean mecanismos alternativos que causan neutropenia en estos pacientes, como la formación de anticuerpos antineutrófilos, daño primario del progenitor granulocítico, por desbalance en la producción de neutrófilos, por anticuerpos contra la glicoproteína gp120 de la cápside viral del VIH, y deficiencias vitamínicas.

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.

    An increasing understanding of the process of erythropoiesis raises some interesting questions about the pathophysiology, diagnosis and treatment of anemia and erythrocytosis. The mechanisms underlying the development of many of the erythrocytoses, previously characterised as idiopathic, have been elucidated leading to an increased understanding of oxygen homeostasis. Characterisation of anemia and erythrocytosis in relation to serum erythropoietin levels can be a useful addition to clinical diagnostic criteria and provide a rationale for treatment with erythropoiesis stimulating agents (ESAs). Recombinant human erythropoietin as well as other ESAs are now widely used to treat anemias associated with a range of conditions, including chronic kidney disease, chronic inflammatory disorders and cancer. There is also heightened awareness of the potential abuse of ESAs to boost athletic performance in competitive sport. The discovery of erythropoietin receptors outside of the erythropoietic compartment may herald future applications for ESAs in the management of neurological and cardiac diseases. The current controversy concerning optimal hemoglobin levels in chronic kidney disease patients treated with ESAs and the potential negative clinical outcomes of ESA treatment in cancer reinforces the need for cautious evaluation of the pleiotropic effects of ESAs in non-erythroid tissues.

    This article provides an overview of the current use of diagnostic imaging modalities in the evaluation of a heterogeneous group of disorders causing chronic anemias by impaired blood cell production (inherited bone marrow failure syndromes of childhood, aplastic anemia and myelodysplastic syndromes, β-thalassemia) or increased blood cell destruction (sickle cell disease). During the course of these disorders, various musculoskeletal abnormalities can be encountered, including marrow hyperplasia, reversion of yellow marrow to red marrow, growth disturbances, and, occasionally, extramedullary hematopoiesis. Diagnostic imaging may help the clinician to identify specific complications related to either the disease (e.g., bone infarction and acute osteomyelitis in sickle cell disease) or transfusion (e.g., iron overload due to increased hemolysis) and iron chelation (e.g., desferrioxamine-related dysplastic bone changes and deferiprone-related degenerative arthritis) treatments. In this field, magnetic resonance imaging plays a pivotal role because of its high tissue contrast that enables early assessment of bone marrow changes before they become apparent on plain films or computed tomography or metabolic changes occur on bone scintigraphy or positron emission tomography scan. Overall, familiarity with the range of radiological appearances in chronic anemias is important to diagnose complications and establish appropriate therapy. PMID:21644200

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.

  14. Aplastic anemia in Japanese radiological technicians

    International Nuclear Information System (INIS)

    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.)

    Full Text Available Lymphangioma is an uncommon malformation of lymphatic system. Multiple colonic lymphangioma named as lymphangiomatosis is considered an extremely rare disease. Although lymphangioma is a benign tumor and most colonic lymphangiomas do not cause symptoms and do not require treatment, resection of lymphangioma is necessary in the presence of symptoms such as abdominal pain, bleeding, intussusceptions. We report a case of colonic lymphangiomatosis in a man who presented with abdominal discomfort and anemia, which was diagnosed and treated with endoscopic snare polypectomy.

    Background. Iron deficiency anemia impacts on cognitive development. The objective of this study was to determine the prevalence of anemia and iron deficiency in children with Down syndrome and identify risk factors for anemia. Methods. We conducted a prolective cross-sectional study of children attending a multidisciplinary Down syndrome medical center. One hundred and forty nine children with Down syndrome aged 0-20 years were enrolled in the study. Information obtained included a medical history, physical and developmental examination, nutritional assessment, and the results of blood tests. Results. Of the patients studied, 8.1% were found to have anemia. Among the 38 children who had iron studies, 50.0% had iron deficiency. In a multivariate analysis, Arab ethnicity and low weight for age were significantly associated with anemia. Gender, height, the presence of an eating disorder, and congenital heart disease were not risk factors for anemia. Conclusions. Children with Down syndrome are at risk for anemia and iron deficiency similar to the general population. Children with Down syndrome should be monitored for anemia and iron deficiency so that prompt intervention can be initiated. PMID:21941570

    Full Text Available Em 1990, as Nações Unidas promoveram a Reunião de Cúpula de Nova Iorque, onde foram traçadas metas para o decênio vindouro, dentre as quais, a redução de um terço na prevalência das anemias nas mulheres em idade fértil. 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.

    longerterm selenium status, while plasma selenium appears to be a marker of short-term nutritional status. The present findings indicate a positive correlation between plasma selenium concentration and the practice of physical activity. Bioavailability studies are required to establish appropriate reference levels of this mineral for the Spanish population.Introducción: El selenio es un micronutriente esencial para la salud del ser humano, debido fundamentalmente a su implicación como cofactor de enzimas con actividad antioxidante que protegen al organismo del daño oxidativo, de modo que una ingesta inadecuada de este mineral está asociada con la aparición y desarrollo de enfermedades crónicas tales como hipertensión, diabetes, enfermedades coronarias, asma y cáncer. Por esta razón, la determinación de selenio plasmático y eritrocitario contribuirá a la valoración del estado nutricional de la población estudiada. Objetivo: El objetivo de estudio fue valorar el estado nutricional de selenio en una población adulta sana en riesgo de deficiencia, a través de una evaluación de la ingesta, así como de los niveles de selenio en plasma y eritrocito, y la actividad de la enzima selenio-dependiente Glutation Peroxidasa (GPx en eritrocito. Material y métodos: El estudio se realizó en un grupo de población de 84 adultos sanos pertenecientes a la provincia de Granada (31 hombres y 53 mujeres en los que se determinó la ingesta de nutrientes y selenio, sus niveles plasmáticos y eritrocitarios, así como su asociación con la actividad de la enzima Glutation Peroxidasa y con diversos factores del estilo de vida. Resultados: Las concentraciones medias de selenio en plasma fueron de 76,6 ± 17,3 μg/L (87,3 ± 17,4 μg/L en los hombres, y de 67,3 ± 10,7 μg/L para las mujeres, mientras que los valores eritrocitarios de selenio de la poblacion total del estudio fue de 104,6 μg/L (107,9 ± 26,1 μg/L en hombres y 101,7 ± 21,7 μg/L en mujeres.

    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. PMID:26818422

    2007-01-01

    Full Text Available Introduction. The problem of anemia in congestive heart failure and chronic kidney disease was thought to be insignificant for a long period of time. Recent investigations pointed out that the problem of anemia should be defined in the context of the cardio-renal anemia syndrome. A positive feedback mechanism indicates that cardio-renal anemia syndrome is due to an interaction between congestive heart failure, chronic renal failure and anemia. The aim of the study was to present the possible pathophysiological mechanisms of this syndrome, epidemiological characteristics and therapeutic results of the former investigations. Results. The results of the retrospective and prospective controlled trails have shown that management of anemia with subcutaneous administration of recombinant human erythropoietin together with intravenous iron infusion for at least 3-6 months lead to: relief of symptoms (improved NYHA functional class; increased left ventricular ejection fraction; reduced cardiovascular morbidity and mortality; reduced number of rehospitalizations; reduced requirements for usual therapeutic agents (especially diuretics; and improved renal function. Conclusion. In patients with heart and kidney disease anemia should be routinely identified and appropriately treated. Subcutaneous recombinant erythropoietin and intravenous iron may significantly improve overall survival and quality of life of these patients. .

    Anemia is a common problem in the neonatal period. Presenting symptoms may suggest numerous possible diagnoses ranging from anemia seen as a normal part of development to anemia due to critical pathology. An illustrative case is presented to highlight the appropriate evaluation of the neonate with significant anemia. Several important features of the evaluation of neonatal anemia are highlighted. The constellation of signs and symptoms that occur in conjunction with the anemia are critical for the evaluation. The evaluation should be performed in a step-wise process that starts by eliminating common causes of anemia. Manual review of the peripheral blood smear with a hematologist can be helpful.

    Full Text Available Background: Anemia during pregnancy is a global public health challenge facing the world today. Prevalence of anemia in pregnancy in all the age groups is higher in India as compared to other developing countries. Objective: This study is aimed at determining the magnitude and to explore the socio-demographic and other correlates of anemia among pregnant women. Methodology: This descriptive study with cross-sectional design was conducted in a tertiary care hospital. Pregnant who were attending antenatal clinic for a period of one year were comprised the study material. Correlation between variables was analyzed using the chi-square and odd ratio. Results: Three hundred and thirty eight pregnant women were registered for the present study, whose age ranged from 16 to 45 years with a mean age of 26.08 years. Majority (81.95% participants were found to be anemic. It was observed that anemia was more prevalent in pregnant women age groups i.e. 25-29 years and 30+years i.e. 86.67% and 86.21% respectively. Anemia was 82.92% in women were belonging to Hindu and others religion and 82.24% in women having vegetarian diet. Maximum prevalence (83.93% of anemia was observed in women who were booked for antenatal care in the 3rd trimester of pregnancy. The prevalence of anemia is higher (>85% in women having parity two or more, but this association was not statistically significant. Very few (6.21% were found to be severely anemic as compared to women who were moderately anemic (43.19%. Multiple logistic regression analysis of these factors showed that possibility of anemia is less in women who belong to rural area and it is highly significant. Analysis further showed significant association between anemia and type of diet and other factors like women having parity 1 and 4. Conclusion: The prevalence of anemia amongst the pregnant participants was very high. The socio-demographic and obstetrics factors were found to be associated with anemia. To prevent

    Anemia and thrombocytopenia are frequent clinical manifestations of myelofibrosis as well as important prognostic factors of the disease. Concerning the treatment of anemia, the first step should be the correction of reversible contributing factors, such as possible iron, folate and vitamin B12 deficiency. Then, treatment options include erythropoiesis stimulating agents, androgens, immunomodulating drugs, corticosteroids, and splenectomy. Anemia responses may also be observed in some patients treated with JAK inhibitors. However, most patients eventually fail to such therapies and become transfusion dependent. Some of the aforementioned therapies can also improve thrombocytopenia, but the responses are usually observed in patients with moderate platelet count decrease. Allogeneic hematopoietic stem cell transplantation, the only curative treatment of myelofibrosis, can be an alternative for selected patients with cytopenias who are refractory to conventional therapies. However, for the majority of patients, the management of anemia and severe thrombocytopenia remains an unmet need. PMID:26891375

Among males the prevalence of anemia was 30.1%, among females 17.1%. Three principal causes of anemia were revealed. The most frequent (42.3%) was microcytic, hypochromic anemia, with low levels of serum iron concentrations, related to gastrointestinal diseases (with chronic occult blood loss). 38.7% of anemic elderly people was affected by chronic diseases. In 19.0% a folate (16 case) and iron (5 cases) deficiency was revealed. These results suggest that anemia in the elderly is always pathological; hemoglobin values lower than 12 g/dl should be considered abnormal and investigated. PMID:1545920

    Anemia is accepted among critically ill patients as an alternative to elective blood transfusion. This practice has been extrapolated to head injury patients with only one study comparing the effects of mild anemia on neurological outcome. There are no studies quantifying microcirculation during anemia. Experimental studies suggest that anemia leads to cerebral hypoxia and increased rates of infarction, but the lack of clinical equipoise, when testing the cerebral effects of transfusion among critically injured patients, supports the need of experimental studies. The aim of this study was to quantify cerebral microcirculation and the potential presence of axonal damage in an experimental model exposed to normovolaemic anemia, with the intention of describing possible limitations within management practices in critically ill patients. Under non-recovered anesthesia, six Merino sheep were instrumented using an intracardiac transeptal catheter to inject coded microspheres into the left atrium to ensure systemic and non-chaotic distribution. Cytometric analyses quantified cerebral microcirculation at specific regions of the brain. Amyloid precursor protein staining was used as an indicator of axonal damage. Animals were exposed to normovolaemic anemia by blood extractions from the indwelling arterial catheter with simultaneous fluid replacement through a venous central catheter. Simultaneous data recording from cerebral tissue oxygenation, intracranial pressure, and cardiac output was monitored. A regression model was used to examine the effects of anemia on microcirculation with a mixed model to control for repeated measures.

    Acquired aplastic anemia (AA) is the typical bone marrow failure syndrome characterized by an empty bone marrow; an immune-mediated pathophysiology has been demonstrated by experimental works as well as by clinical observations. Immunusuppressive therapy (IST) is a key treatment strategy for aplastic anemia; since 20 years the standard IST for AA patients has been anti-thymocyte globuline (ATG) plus cyclosporine A (CyA), which results in response rates ranging between 50% and 70%, and even hi...

    Anemia is a frequent finding in most diseases which cause malabsorption. The most frequent etiology is the combination of iron and vitamin B12 deficiency. Celiac disease is frequently diagnosed in patients referred for evaluation of iron deficiency anemia (IDA), being reported in 1.8%-14.6% of patients. Therefore, duodenal biopsies should be taken during endoscopy if no obvious cause of iron deficiency (ID) can be found. Cobalamin deficiency occurs frequently among elderly patients, but it is...

    Iron deficiency is more common in women due to uterine bleeding, which affects them throughout their fertile life. Additionally, iron needs increase physiologically during pregnancy and breastfeeding. Pregnant women therefore constitute one of the risk groups for iron deficiency. During the postpartum period, iron deficiency is the most common cause of anemia. Longer hospital stays and greater susceptibility to infections are potential consequences of postpartum anemia.

    Abstract Many patients with congestive heart failure (CHF) fail to respond to maximal CHF therapy and progress to end stage CHF with many hospitalizations, very poor quality of life, end stage renal failure, or die of cardiovascular complications within a short time. One factor that has generally been ignored in many of these patients is the fact that they are often anemic.The anemia is due mainly to renal failure but also to the inhibitory effects of cytokines on the bone marrow. Anemia itself may further worsen the cardiac function and make the patients resistant to standard CHF therapies. Indeed anemia has been associated with increased severity of CHF, increased hospitalization, worse cardiac function and functional class, higher doses of diuretics,worsening of renal function and reduced quality of life. In both controlled and uncontrolled studies the correction of the anemia with erythropoietin (EPO) and oral or Ⅳ iron is associated with improvement in all these parameters. EPO itself may also play a direct role in improving the heart unrelated to the improvement of the anemia. Anemia may also play a role in the worsening of coronary heart disease even without CHF.

    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.

    Full Text Available Anemia of cancer (AC may contribute to cancer-related fatigue and impair quality of life. Improved understanding of the pathogenesis of AC could facilitate better treatment, but animal models to study AC are lacking. We characterized four syngeneic C57BL/6 mouse cancers that cause AC. Mice with two different rapidly-growing metastatic lung cancers developed the characteristic findings of anemia of inflammation (AI, with dramatically different degrees of anemia. Mice with rapidly-growing metastatic melanoma also developed a severe anemia by 14 days, with hematologic and inflammatory parameters similar to AI. Mice with a slow-growing peritoneal ovarian cancer developed an iron-deficiency anemia, likely secondary to chronically impaired nutrition and bleeding into the peritoneal cavity. Of the four models, hepcidin mRNA levels were increased only in the milder lung cancer model. Unlike in our model of systemic inflammation induced by heat-killed Brucella abortus, ablation of hepcidin in the ovarian cancer and the milder lung cancer mouse models did not affect the severity of anemia. Hepcidin-independent mechanisms play an important role in these murine models of AC.

  2. Correlative study on anemia and radiotherapy effects in nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    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

    2005-10-01

    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 Iron deficiency and anemia are associated with impaired neurocognitive development and immune function in young children. Total body iron, calculated from serum ferritin and soluble transferrin receptor concentrations, and hemoglobin allow for monitoring of the iron and anemia status of children in the United States. The purpose of this analysis is to describe the prevalence of iron deficiency (ID, anemia, and iron deficiency anemia (IDA among children 1–5 years using data from the 2007–2010 National Health and Nutrition Examination Survey (NHANES. Prevalence of ID, anemia, and IDA among children 1–5 years was 7.1% (5.5, 8.7, 3.2% (2.0, 4.3, and 1.1% (0.6, 1.7, respectively. The prevalence of both ID and anemia were higher among children 1–2 years (p < 0.05. In addition, 50% of anemic children 1–2 years were iron deficient. This analysis provides an update on the prevalence of ID, anemia, and IDA for a representative sample of US children. Our results suggest little change in these indicators over the past decade. Monitoring of ID and anemia is critical and prevention of ID in early childhood should remain a public health priority.

    Full Text Available Quadros hemolíticos não eritrorregenerativos são descritos em cães e podem ser decorrentes de doença medular primária, bem como, da destruição dos precursores eritróides medulares por imunoglobulinas. Um cão macho, de três anos de idade, sem raça definida, foi atendido no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo apresentando sinais de anemia hemolítica aguda arregenerativa. Após a instituição de terapia imunossupressora (prednisona, houve remissão da hemólise sem, no entanto, sinais de eritrorregeneração. No décimo dia de tratamento, o mielograma demonstrou discreta hipoplasia e displasia eritróide, descartando a possibilidade de aplasia medular. Associou-se ciclofosfamida e azatioprina ao tratamento, tendo havido resposta eritrorregenerativa e recuperação dos valores hematológicos. A ocorrência deste caso de anemia hemolítica não eritrorregenerativa deve servir como alerta para a ocorrência desta condição mórbida, como também, da importância da utilização do mielograma como método auxiliar no diagnóstico de anemias arregenerativas.Nonregenerative forms of immune-mediated hemolytic anemia has been describe in dogs and are attributed to bone marrow diseases or immune-mediated destruction of erythroid progenitors.

    International Nuclear Information System (INIS)

    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.

    2007-01-01

    Full Text Available Introduction: Anemia is more common and pronounced in patients with diabetic, than in patients with non-diabetic renal disease. While several factors contribute to its pathogenesis, the failure of the kidney to increase erythropoietin in response to falling hemoglobin appears to be the dominant factor. The most frequent complications of anemia in diabetic patients include decreased quality of life and work capacity and increased cardiovascular morbidity and mortality. Material and Methods: This cross-sectional multicenter study included a total of 539 patients with type I (~20% and type II diabetes (~80% classified into five stages according to the glomerular filtration rate. Results Diabetic nephropathy appears in stage I, and progresses in all patients to the stage V (p=0.045. The presence of anemia progressively increased from stage I to stage V (from 60% to 100%, p=0.008. Only 62% of patients with anemia were treated (mainly with iron and only 3.4% received erythropoietin treatment. Hypertension was present in 90% of patients in stage I and in 100% of patients in stage V nephropathy. The presence of heart failure increased from 0% (stage I to 51% (stage IV, p=0.03. Around 62% of patients were referred to a nephrologist, and according to the logistic regression model, renal failure and presence of anemia were significant predictors of patients' referral to nephrologist. Conclusion: In a primary care setting, anemia is a frequent finding, even in the very beginning of diabetic renal disease. Currently available guidelines for management of anemia are not followed; this may explain high percentage of patients with heart failure in pre-dialysis stage. Early referral to a nephrologist and regular follow-up by an endocrinologist and cardiologist are the best way for the prevention of diabetic complications and comorbidity.

    Full Text Available Over the past few years complete blood count (CBC by the automated hematology analyzers and microscopic examination of peripheral smear have complemented each other to provide a comprehensive report on patients’ blood sample. Numerous classifications for anemia have been established and the important parameters involved in the classifications are Hb, HCT, MCV, RDW, MCH, MCHC, reticulocytes and IRF. Many of these values are obtained only by automated heamatology analyzers. One histogram graph is worth 1000 numbers. A large collection of data, displayed as a visual image, can convey information with far more impact than the numbers alone. In hematology, these data take on several forms, one of which is the RBC histogram. Therefore a study of variation in RBC histograms in various anemias. Many times it is seen that histogram patterns show varying features when a simultaneous peripheral smear is reported. It is also seen that there are many limitations when manual peripheral smears reporting is done for example: peripheral smear reports are subjective, labor intensive and statistically unreliable. However microscopic peripheral smear examination also has their advantages. This study intends to create a guide to laboratory personnel and clinicians with sufficient accuracy to presumptively diagnose morphological classes of anemia directly from the automated hematology cell counter forms and correlate with morphological features of peripheral smear examination. OBJECTIVE: 1. The objective of the study is to know the utility and advantage of red cell histograms. 2. To study the automated histogram patterns along with morphological features noticed on peripheral smear examination. SOURCE OF DATA: All anemic patients from Central Diagnostic Laboratory of A.J.IMS. METHOD OF COLLECTION OF DATA: A total of about 100 patients were included in the study. Complete blood count including HB, TC, DC, Platelet count hematocrit value, RBC indices was obtained

    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.

    Aplastic anemia is a rare complication of thymoma and is extremely infrequent after thymectomy. We present a case of a 60-year-old woman with very severe aplastic anemia appearing sixteen months after thymectomy for a thymoma. She underwent thymectomy for a thymoma in April 2000. Preoperative examination revealed no hematologic abnormality. About sixteen months after the operation, she was readmitted because of pancytopenia with cough and fever. Bone marrow aspiration revealed a very severe hypoplasia in all the three cell lines with over 80% fatty tissue, and chest CT revealed no recurrence of thymoma. Her aplastic anemia had responded to cyclosporine A and granulocyte-colony stimulating factor (G-CSF). PMID:12760272

  13. Assessment of anemia during CT pulmonary angiography

    International Nuclear Information System (INIS)

    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.

    The aim of this study was to establish the prevalence of anemia in stable pediatric renal transplant recipients and to examine the association of anemia with renal function, immunosuppressants, angiotensin converting enzyme inhibitors, and growth, as well as iron, vitamin B(12), and folate stores. This is a cross-sectional study of the 50 renal transplant recipients currently followed at our center. Patient data were collected regarding hematological parameters, growth, medications, renal function, underlying renal disease, delayed graft function, episodes of rejection, and iron or erythropoietin therapy post transplantation. The mean hemoglobin level (Hb) was 110 g/l and the overall prevalence of anemia was 60%, including 30% who were severely anemic (Hb<100 g/l). There was a high rate of iron deficiency (34%) and serum iron was the parameter of iron metabolism most closely associated with anemia. Hb in patients with low serum iron was 90.7 g/l versus 114.4 g/l in those with normal serum iron ( P<0.01). Both univariate and multiple linear regression determined tacrolimus dose and creatinine clearance to be significant factors associated with anemia. Tacrolimus dose correlated with a 10 g/l reduction in Hb for every increase of tacrolimus dose of 0.054 mg/kg per day ( P=0.001). The dose of mycophenolate was positively correlated with Hb, but this was likely to be confounded by our practice of dose reduction in the setting of anemia. Angiotensin converting enzyme inhibitor use was not associated with anemia. Severely anemic patients tended to be shorter, with a mean Z-score for height of -1.8 compared with -0.9 for those with normal Hb ( P=0.02). Anemia is a significant and common problem in pediatric renal transplant patients. Deteriorating renal function is an important cause, but other factors like iron deficiency and immunosuppression are involved. Definition of iron deficiency is difficult and serum iron may be a valuable indicator. Medication doses

    1995-05-01

    Sickle cell anemia, a common disorder associated with reduced life span of the red blood cell and vasoocclusive events, is caused by a mutation in the {Beta}-hemoglobin gene. Yet, despite this genetic homogeneity, the phenotype of the disease is heterogeneous. This suggests the modulating influence of associated inherited traits. Some of these may influence the accumulation of fetal hemoglobin, a hemoglobin type that interferes with the polymerization of sickle hemoglobin. Another inherited trait determines the accumulation of {alpha}-globin chains. This review focuses on potential genetic regulators of the phenotype of sickle cell anemia. 125 refs., 6 figs., 3 tabs.

    X-linked sideroblastic anemia (XLSA) is a rare hereditary disorder that typically manifests in males as microcytic anemia. Here, we report a family with XLSA that affects females and manifests as macrocytic anemia. The proband was a Japanese woman harboring a heterozygous mutation c.679C>T in the ALAS2 gene. This mutation causes the amino acid substitution R227C, which disrupts the enzymatic activity of erythroid-specific δ-aminolevulinic acid synthase. The mutation was not detected in the ALAS2 complementary DNA from peripheral blood red blood cells of the proband, indicating that the cells were mostly derived from erythroblasts expressing wild-type ALAS2. The proband's mother, who had been diagnosed with myelodysplastic syndrome, also had XLSA with the same mutation. Clinicians should be aware that XLSA can occur not only in males but also in females, in whom it manifests as macrocytic anemia. PMID:26862056

    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. PMID:27542426

    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

Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and con-venient, 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.

  8. Fanconi anemia proteins in telomere maintenance.

    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.

    Full Text Available OBJECTIVE: Post-transplant anemia is a common complication in renal allograft recipients. The most common causes are impaired graft function, immunosuppressive drugs, and infections. The aim of our study was to further investigate the prevalence of anemia before and after renal transplantation in renal allograft recipients in Turkey. MATERIAL and METHODS: We assessed 464 patients who received a kidney transplant between the years 2010 and 2012. The prevalence of anemia was evaluated before transplantation and at the 3 rd and at 6th months after transplantation. Our study is a retrospective study. RESULTS: The prevalence of anemia at the 6th month after the transplant surgery was 28.8%. The percentage of the patients who did not have anemia prior to the transplant surgery, and who developed anemia after the transplantation was 24.4%. CONCLUSION: Our findings are similar to those found in the literature, and show that anemia is a very common entity after renal transplantation.

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.

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.

    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

  1. Schilling evaluation of pernicious anemia: current status

    International Nuclear Information System (INIS)

    The Schilling examination remains a popular means of evaluating in vivo absorption of vitamin B12. When absorption is abnormally low, the test may be repeated with addition to exogenous intrinsic factor (IF) in order to correct the IF deficiency that characterizes pernicious anemia. A dual-isotope variation provides a means of performing both stages of the test simultaneously, thereby speeding up the test and reducing dependence on complete urine collection. In vivo studies indicate that, when administered simultaneously, the absorption of unbound B12 is elevated, and IF-bound B12 is reduced, in pernicious-anemia patients, relative to the classic two-stage examination. A number of clinical studies indicate significant difficulty in resolving clincial diagnoses with the dual-tracer test. An algorithm is offered for selecting the most suitable variation of the Schilling test to improve the accuracy of test results and the ease of performance

    Full Text Available The adequacy of a hemoglobin concentration in a given clinical situation depends on whether a sufficient amount of oxygen is carried to the tissues to meet metabolic requirements. Therefore, the decision to transfuse a given patient cannot be based only on the hemoglobin level. Rather, rigid adherence to an arbitrarily predefined transfusion threshold will result in the over-transfusion of some patients, but also in the under-transfusion of others. A better knowledge of the physiologic responses developed during acute isovolemic anemia and the clinical factors that can limit the ability of the organism to maintain adequate tissue oxygenation in these situations, will allow the clinician to better define the transfusion trigger for each patient. This paper reviews the physiological and clinical factors of acute isovolemic anemia and presents the therapeutic options available.

    1992-05-01

    Chronic renal failure is almost invariably accompanied by symptomatic anemia. It has been demonstrated that the primary cause of this anemia is inadequate production of erythropoietin by the diseased kidneys. The isolation of erythropoietin, followed by the cloning and expression of the human erythropoietin gene, made possible clinical trials of rHuEPO in uremic patients. rHuEPO produced dramatic increases in the hematocrit in almost all patients treated and also ameliorated many symptoms, such as lethargy, dizziness, and poor appetite, that had long been attributed to the effect of uremic toxins. Adverse effects of treatment with rHuEPO noted in the early clinical trials included hypertension, seizures, arteriovenous fistula or shunt thrombosis, and hyperkalemia. Further study of rHuEPO has shown that many of these side effects may be no more frequent in patients receiving rHuEPO than in other uremic patients not receiving rHuEPO. Reduction of the rHuEPO dosage and subcutaneous administration produce less rapid increases in the hematocrit and may lessen the incidence and severity of these side effects. rHuEPO therapy places great demands on both the body's iron stores and the capacity to rapidly transfer iron from storage sites to the erythroid progenitor cells. Thus, almost all patients treated with rHuEPO become iron deficient and require oral or parenteral iron replacement. Response to rHuEPO in uremic patients is diminished if the anemia is complicated by iron deficiency, inflammatory disorders, aluminum overload, or deficiency of folate or vitamin B12. rHuEPO therapy is safe and effective in the treatment of the anemia of chronic renal failure. The use of rHuEPO leads to enhanced quality of life and eliminates the need for red cell transfusions. In addition to hemodialysis patients, predialysis patients and those on CAPD benefit from and are candidates for rHuEPO therapy. PMID:1578966

    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.

  9. Iron, anemia and hepcidin in malaria

    Directory of Open Access Journals (Sweden)

    Natasha eSpottiswoode

    2014-05-01

    Full Text Available Malaria and iron have a complex but important relationship. Plasmodium proliferation requires iron, both during the clinically silent liver stage of growth and in the disease-associated phase of erythrocyte infection. Precisely how the protozoan acquires its iron from its mammalian host remains unclear, but iron chelators can inhibit pathogen growth in vitro and in animal models. In humans, iron deficiency appears to protect against severe malaria, while iron supplementation increases risks of infection and disease. Malaria itself causes profound disturbances in physiological iron distribution and utilization, through mechanisms that include hemolysis, release of heme, dyserythropoiesis, anemia, deposition of iron in macrophages, and inhibition of dietary iron absorption. These effects have significant consequences. Malarial anemia is a major global health problem, especially in children, that remains incompletely understood and is not straightforward to treat. Furthermore, the changes in iron metabolism during a malaria infection may modulate susceptibility to coinfections. The release of heme and accumulation of iron in granulocytes may explain increased vulnerability to non-typhoidal Salmonella during malaria. The redistribution of iron away from hepatocytes and into macrophages may confer host resistance to superinfection, whereby blood-stage parasitemia prevents the development of a second liver-stage Plasmodium infection in the same organism. Key to understanding the pathophysiology of iron metabolism in malaria is the activity of the iron regulatory hormone hepcidin. Hepcidin is upregulated during blood-stage parasitemia and likely mediates much of the iron redistribution that accompanies disease. Understanding the regulation and role of hepcidin may offer new opportunities to combat malaria and formulate better approaches to treat anemia in the developing world.

    Iron deficiency anemia (IDA) is a common hematologic condition, affecting a substantial proportion of the world's women and young children. Optimal management of IDA requires an accurate diagnosis, identification and correction of the underlying cause, provision of medicinal iron therapy, and confirmation of treatment success. There are limited data to support current treatment approaches regarding oral iron preparation, dosing, monitoring, and duration of therapy. New intravenous iron agents have improved safety profiles, which may foster their increased utilization in the treatment of patients with IDA. Clinical trials focused on improving current treatment standards for IDA are sorely needed. PMID:25064710

    Full Text Available Background. Anemia is a common condition in the elderly and a significant risk factor for increased morbidity and mortality, reducing not only functional capacity and mobility but also quality of life. Currently, few data are available regarding anemia in hospitalized geriatric patients. Our retrospective study investigated epidemiology and causes of anemia in 405 hospitalized geriatric patients. Methods. Data analysis was performed using laboratory parameters determined during routine hospital admission procedures (hemoglobin, ferritin, transferrin saturation, C-reactive protein, vitamin B12, folic acid, and creatinine in addition to medical history and demographics. Results. Anemia affected approximately two-thirds of subjects. Of 386 patients with recorded hemoglobin values, 66.3% were anemic according to WHO criteria, mostly (85.1% in a mild form. Anemia was primarily due to iron deficiency (65%, frequently due to underlying chronic infection (62.1%, or of mixed etiology involving a combination of chronic disease and iron deficiency, with absolute iron deficiency playing a comparatively minor role. Conclusion. Greater awareness of anemia in the elderly is warranted due to its high prevalence and negative effect on outcomes, hospitalization duration, and mortality. Geriatric patients should be routinely screened for anemia and etiological causes of anemia individually assessed to allow timely initiation of appropriate therapy.

    Full Text Available Introduction. Iron deficiency anemia and thalassemia are the most common causes of microcytic anemia. Powerful statistical computer programming enables sensitive discriminant analyses to aid in the diagnosis. We aimed at investigating the performance of the multiple discriminant analysis (MDA to the differential diagnosis of microcytic anemia. Methods. The training group was composed of 200 β-thalassemia carriers, 65 α-thalassemia carriers, 170 iron deficiency anemia (IDA, and 45 mixed cases of thalassemia and acute phase response or iron deficiency. A set of potential predictor parameters that could detect differences among groups were selected: Red Blood Cells (RBC, hemoglobin (Hb, mean cell volume (MCV, mean cell hemoglobin (MCH, and RBC distribution width (RDW. The functions obtained with MDA analysis were applied to a set of 628 consecutive patients with microcytic anemia. Results. For classifying patients into two groups (genetic anemia and acquired anemia, only one function was needed; 87.9% β-thalassemia carriers, and 83.3% α-thalassemia carriers, and 72.1% in the mixed group were correctly classified. Conclusion. Linear discriminant functions based on hemogram data can aid in differentiating between IDA and thalassemia, so samples can be efficiently selected for further analysis to confirm the presence of genetic anemia.

    Full Text Available Introduction: Anemia is one of the most important nutritional deficiencies affecting various social and socioeconomic strata. It is more common in developing countries, with children and adolescents being at a significantly higher risk for the condition. Objective: To perform a literature review on iron deficiency anemia in adolescence as a public health issue and on the risk factors that may contribute towards nutritional deficiencies, stunted growth and development in this age group, emphasizing the physiopathology and causes of anemia, the different diagnostic approaches, and its clinical characteristics, prevention and treatment. Methodology: The LILACS-BIREME, SCIELO and PUBMED databases were consulted for the study. Scientific papers published in Spanish, Portuguese or English between 2000 and 2013 on the subject of iron deficiency anemia in adolescents were selected for inclusion. A total of 102 studies published between January 1st, 2000 and June 30th, 2013 were identified and evaluated. Forty-two articles meeting the inclusion criterion (adolescents with anemia were selected for this review. Finally, an analysis was conducted and the papers were evaluated in accordance with the study objectives. Results and Discussion: The studies reviewed revealed a prevalence of iron deficiency anemia of around 20% in adolescents and described the harmful effects of anemia in this age group. Conclusion: Preventive action is required with respect to iron deficiency anemia. Healthcare professionals should be aware of the need for early diagnosis, prophylaxis and treatment.

    As a common problem in long-term care facilities (LTCFs), anemia affects 25-63% of the elderly. The aim of the present study was to describe the prevalence and characteristics of anemia and its associated factors in the institutionalized elderly. The cross-sectional study was carried out with three hundred thirteen individuals aged ≥ 60 years, of both genders, living in long-term care facilities for the elderly in Salvador, Bahia, Brazil. Poisson regression (PR) with robust variance estimates was used to assess the factors related to anemia. The prevalence of anemia was 38%. Mild anemia was predominant in both genders (male: 26.8%; female: 21.1%), as normocytic and normochromic anemia, with no anisocytosis (69.75%). Anemia was associated with thinness (PR: 1.68; 95% CI: 1.04-2.72) and with moderate (PR: 1.98; 95% CI: 1.07-3.63) and total (PR: 2.61; 95% CI: 1.34-5.07) dependence in the final model. Severe dependence exhibited borderline significance (PR: 1.94; 95% CI: 1.00-3.77). The prevalence of anemia was high in the institutionalized elderly in both genders, with characteristics suggesting chronic diseases as the causal factor, and the frequency of occurrence was higher in thinness elderly with moderate to total dependence.

    A urinary iron excretion test was carried out in 22 patients with iron deficiency anemia. The iron excretion index was significantly higher in patients with intractable iron deficiency anemia compared with normal subjects and anemic patients who were responsive to iron therapy. The findings suggest that iron excretion may be a factor that modulates the response of patients to iron therapy.

    Full Text Available En España, en los últimos años, se han experimentado múltiples cambios en la prevención y la atención de las personas con discapacidad, en particular en lo que se refiere a las personas sordas. La interpretación de la sordera no sólo como deficiencia auditiva, sino como una diferencia comunicativa, está llevando a la disposición de contextos educativos con carácter bilingüe y bicultural. Esta nueva perspectiva conceptual y la consecuente orientación de las prácticas escolares tienen un impacto positivo en los campos de la salud, la educación y el ámbito social, fomentando el desarrollo tanto del alumnado sordo, como del alumnado oyente. En este artículo se expone la situación del contexto español en este campo, y ha servido de base para la realización de un proyecto transnacional europeo.

    Anemia is a frequent extraintestinal manifestation of inflammatory bowel disease (IBD) that is commonly overlooked, despite its significant impact on quality of life. Characteristic symptoms include chronic fatigue, headache, and subtle impairment of cognitive function, although some less common symptoms include dyspnea, dizziness, pica, angular stomatitis, shortened attention span, and esophageal webs. Several types of anemia are associated with IBD, but iron deficiency anemia (IDA) accounts for the majority of cases and others include anemia of chronic disease, anemia associated with vitamin deficiency (vitamin B12 and folate), autoimmune anemia, and anemia caused by medication used to treat IBD. The diagnosis of IDA relies on laboratory blood tests. Therefore, these tests should be obtained on a regular basis because characteristic symptoms may be absent or not readily recognized by patients and their clinicians. Complete blood count may suffice; however, iron studies and serum vitamin levels may be necessary to differentiate between specific types of anemia. During the diagnostic process, it is important to consider coexistence of different types of anemia, especially if no response to therapy is noted. The therapy for anemia is directed towards treatment of the underlying inflammatory process and supplemental therapy, depending on the type of deficiency. Iron deficiency anemia is treated with iron preparations, first orally, and if unresponsive or if associated with untoward adverse events leading to decrease in adherence with the therapeutic regimen, with intravenous preparations. Intramuscular therapy has been abandoned due to high rate of complications. Intravenous therapy may be administered as a multiple-dose regimen (intravenous iron sucrose and gluconate) or as a single intravenous dose (iron dextran), which is associated with a higher risk of allergic infusion reactions and requires obligatory test dose administration. Treatment with erythropoietin is

    Full Text Available Thiamine responsive megaloblastic anemia (TRMA is an autosomal recessive disorder, which is caused by loss of function mutations in the SLC19A2 gene. TRMA is characterized by anemia, deafness, and diabetes mellitus. We now report two sisters, the eldest of which presented to a different hospital during childhood with sensorineural deafness, which was treated with a hearing prosthesis, insulin requiring diabetes, megaloblastic anemia. The younger sister is also affected with sensorineural deafness along with diabetes and megaloblastic anemia. Because a diagnosis of TRMA was suspected, therapy with insulin and thiamine was started to which the child is responding. Diabetes associated with deafness and megaloblastic anemia, suggests a diagnosis of TRMA.

    Hookworm infections as well as other intestinal nematodiases are endemic in China. In this case, a 70-year-old male showed symptoms of chest tightness, shortness of breath, and both lower extremities edema. The diagnostic result was chronic renal insufficiency, chronic kidney disease (5th stage), and renal anemia at first. Then, he received treatment with traditional drugs. However, this treatment did not help to alleviate the symptoms of the patient significantly. The results of gastroendoscopy showed hookworms in the duodenum, also confirmed by pathology examination. Anemia was markedly ameliorated after eliminating the parasites. The results mentioned above suggested that ancylostomiasis was the leading causes of anemia in this patient, and the etiology of anemia in uremic patients should be systematically considered. Especially when anemia could not be cured by regular treatments, rare diseases should be investigated. PMID:27417086

    Full Text Available Flow cytometric reticulocyte analysis allows the evaluation of reticulocyte maturity. New reticulocyte parameters have been used in the diagnosis and management of anemias, in the bone marrow transplant setting and in the monitoring of iron replacement or erythropoiet in therapy. Reticulocyte numbers and maturation levels have been studied in different hemoglobinopathies and the results have been correlated with the degree of ineffective erythropoiesis. In order to verify differences in reticulocyte parameters in various types of anemias and to test the absolute number of immature reticulocytes as a possible discriminating factor among various types of anemias, reticulocyte counts were performed on 219 samples from patients with sickle cell anemia (SS (n= 62, hemoglobin S trait (n=9, Sbeta thalassemia (n=7, hemoglobin SC disease (n=11, beta thalassemia trait (n=33 and iron deficiency anemia (n= 47, and non-anemic individuals (n= 50. Mean fluorescence index (MFI was defined as representative of the degree of reticulocyte immaturity and it was evaluated as a percentage and in absolute values. Reticulocyte counts and MFI values were significantly higher in SS, Sbeta thalassemic and SC groups when compared to controls, but not different among the three anemia groups. Patients with hemoglobin S trait, iron deficiency anemia and beta thalassemia trait showed reticulocyte parameters similar to the non-anemic group. There was no difference between the b thalassemic trait and iron deficiency anemia in relation to any parameters. MFI in absolute numbers were significantly higher in anemias that develop with the hemolytic process, although this was not evident in MFI percentage values. Our results showed that the erythoid expansion in sickle cell diseases (SS, SC and Sb thalassemia leads to an enhanced immature reticulocyte release from bone marrow and that the phenomena is more evident by the MFI counting in absolute figures than in percentages.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate socio-economic and demographic determinants of anemia among Indian children aged 6-59 months. METHODS: Statistical analysis was performed on the cross-sectional weighted sample of 40,885 children from 2005 to 2006 National Family Health Survey by using multinomial logistic regression to assess the significance of some risk factors in different degrees of child anemia. Anemia was diagnosed by World Health Organization (WHO cut-off points on hemoglobin level. Pearson's chi-squared test was applied to justify the associations of anemia with different categories of the study population. RESULTS: The prevalence of anemia was 69.5%; 26.2% mild, 40.4% moderate, and 2.9% severe anemia. Overall prevalence rate, along with mild and moderate cases, showed an increasing trend up to 2 years of age and then decreased. Rural children had a higher prevalence rate. Of 28 Indian states in the study, 10 states showed very high prevalence, the highest being Bihar (77.9%. Higher birth order, high index of poverty, low level of maternal education, mother's anemia, non-intake of iron supplements during pregnancy, and vegetarian mother increased the risks of all types of anemia among children (p < 0.05. Christian population was at lower risk; and Scheduled Caste, Scheduled Tribe, and Other Backward Class categories were at higher risk of anemia. CONCLUSION: The results suggest a need for proper planning and implementation of preventive measures to combat child anemia. Economically under-privileged groups, maternal nutrition and education, and birth control measures should be priorities in the programs.

    Full Text Available Introduction. Cameron lesions are linear gastric ulcers or erosions positioned on the crests of mucosal folds at the diaphragmatic impression, in patients with large hiatal hernia, and can cause iron deficiency anaemia. Case report. We present a case of a 56-year-old woman who was referred to our institution for further investigation after she was examined in gastroenterology emergency room (GER for signs and symptoms of severe hypochromic microcytic anemia without signs of acute gastrointestinal bleeding and with no obvious cause of chronic blood loss. Endoscopy showed linear ulceration at the level of diaphragm-Cameron lesions with large hiated hernia. She was treated with proton pump inhibitors and iron supplements. The laparoscopic fundoplication was done. Six months later she was asymptomatic. Conclusion. Large hiatus hernia may cause iron deficiency anemia due to occult bleeding from Cameron erosions. The current therapy concept includes the surgical reconstruction of the hiatus together with gastric fundoplication in combination with the proton pump inhibitor therapy.

    2012-11-01

    Sickle Cell Anemia is a disorder of the microcirculation caused by a genetic point mutation that produces an altered hemoglobin protein called HbS. HbS self-assembles reversibly into long rope like fibers inside the red blood cells. The resulting distorded sickled red blood cells are believed to block the smallest capillaries of the tissues producing anemia. Despite the large amount of work that provided a thorough understanding of HbS polymerization in bulk as well as in intact red blood cells at rest, no consequent cellular scale approaches of the study of polymerization and its link to the capillary obstruction have been proposed in microflow, although the problem of obstruction is in essence a circulatory problem. Here, we use microfluidic channels, designed to mimic physiological conditions (flow velocity, oxygen concentration, hematocrit...) of the microcirculation to carry out a biomimetic study at the cellular scale of sickled cell vaso-occlusion. We show that flow geometry, oxygen concentration, white blood cells and free hemoglobin S are essential in the formation of original cell aggregates which could play a role in the vaso-occlusion events.

    Full Text Available Warm autoimmune hemolytic anemia (WAIHA is one of four clinical types of autoimmune hemolytic anemia (AIHA, with the characteristics of autoantibodies maximally active at body temperature. It produces a variable anemia—sometimes mild and sometimes severe. With respect to the absence or presence of an underlying condition, WAIHA is either idiopathic (primary or secondary, which determines the treatment strategies in practice. Conventional treatments include immune suppression with corticosteroids and, in some cases, splenectomy. In recent years, the number of clinical studies with monoclonal antibodies and immunosuppressants in the treatment of WAIHA increased as the knowledge of autoimmunity mechanisms extended. This thread of developing new tools of treating WAIHA is well exemplified with the success in using anti-CD20 monoclonal antibody, Rituximab. Following this success, other treatment methods based on the immune mechanisms of WAIHA have emerged. We reviewed these newly developed immunotherapy treatments here in order to provide the clinicians with more options in selecting the best therapy for patients with WAIHA, hoping to stimulate researchers to find more novel immunotherapy strategies.

  12. Aplastic anemia and related disorders in atomic bomb survivors

    International Nuclear Information System (INIS)

    Whether the incidence of aplastic anemia significantly increases due to the later effect of atomic-bomb radiation was studied. After the data of aplastic anemia which occurred within 1950 - 1973 were evaluated and the diagnoses of the cases were certified, the incidence of aplastic anemia per 109,000 inhabitants of the cities of Hiroshima and Nagasaki was calculated and compared according to the dose of atomic-bomb radiation. There was no increase in the incidence according to an increase in radiation dose, and there was no fact that aplastic anemia increased in a certain period either. Most of the atomic-bomb survivors who were close to the epicenter and were clinically diagnosed as aplastic anemia had leukemia lesion or myeloid proliferating lesion, and it is likely to be that pathological changes resembling aplastic anemia may appear in a certain phase of myeloid proliferation or as a phenotype of myeloid proliferation. An evaluation was made on cases of aplastic anemia of other groups, but the doses of atomic-bomb radiation which they received were not so much to give effect on the bone marrow except only two cases.

The subjects who were made up of 1830 males and females between the ages of 2 months to 86 years, were divided into the following age groups (0–5, 5–11, 12–14, 15–19, 20–49, ≥50 years. Results showed that the prevalence of anemia was 3% in adult males and 17% in females. The prevalence of ID varied according to age between 4% (≥50 years and 21% (5–11 years and 9% (12–14 years and 23% (15–19 years, respectively, in males and females. The prevalence of anemia and ID was higher in females compared to males. Adults with normal ferritin level, but with low RBC folate and vitamins A and B12 levels had higher prevalence of anemia than those with normal RBC folate and vitamins A and B12 levels. This first nationally representative nutrition and health survey in Kuwait indicated that anemia and ID are prevalent and ID contributes significantly to anemia prevalence.

    Anemia is a frequent complication in patients with inflammatory bowel disease (IBD), and is associated with decreased quality of life and increased rate of hospitalization. The primary therapeutic targets of IBDassociated anemia are iron deficiency and anemia of chronic disease. An important prognostic parameter of the success or failure of therapy is the outcome of the underlying disease. Iron deficiency should be appropriately managed with iron supplementation.However, the use of oral iron therapy is limited by several problems, the most important being gastrointestinal side effects leading occasionally to disease relapse and poor iron absorption. Intravenous iron preparations are more reliable, with iron sucrose demonstrating the best efficacy and tolerability. Treatment with erythropoietin or darbepoetin has been proven to be effective in patients with anemia, who fail to respond to intravenous iron. Patients with ongoing inflammation have anemia of chronic disease and may require combination therapy comprising of intravenous iron sucrose and erythropoietin. After initiating treatment, careful monitoring of hemoglobin levels and iron parameters is needed in order to avoid recurrence of anemia. In conclusion, anemia in the setting of IBD should be aggressively diagnosed, investigated, and treated. Future studies should define the optimal dose and schedule of intravenous iron supplementation and appropriate erythropoietin therapy in these patients.

    objectives To demonstrate the phenomena and explore the causes of anemia in patients with chronic heart failure (CHF). Methods To observe the phenomena of anemia in patients with CHF, a total of 276 patients with CHF were included in this retrospective study. The clinical characteristics of the patients are: mean age 69.2±11.0 years; male 151,female 125; NYHA Ⅲ and Ⅳ 115 (41.7%). Results ①Among the 276 patients with CHF, 81 (29.4%)had anemia (Mean hemoglobulin concentration 101.5±13.0g/L). ② Patients with Anemia were more likely to be female and to have greater NYHA (Ⅲ or Ⅳ) (P<0.05), higher serum creatinine, as well as lower serum albumin and low-density lipoprotein levels (P<0.01).③ A weak negative correlation was also noted between the level of NYHA and hemoglobulin. ④ There was no significant difference in age, the primary cardiac etiology of the CHF, the history of diabetes, left ventricular end diastolic diameter, and left ventricular ejection fraction between CHF patient with and without anemia. Conclusions The prevalence of anemia is high among patients with CHF. The anemia patients with CHF tend to be female, have greater cardiac and renal functional impairment, but with lower serum albumin and LDL that suggests some degree of malnutrition.

    The influence of anemia on outcome in stable outpatients with peripheral artery disease (PAD) has not been consistently investigated. We used data from the Factores de Riesgo y ENfermedad Arterial (FRENA) Registry to compare ischemic events and mortality rates in stable outpatients with symptomatic PAD and anemia. Of 1663 patients with PAD, 208 (12.5%) had anemia. Over 18 months, patients with anemia had a higher rate of myocardial infarction (MI; rate ratio [RR]: 2.10; 95% confidence interval [CI]: 1.04-3.99), limb amputation (RR: 2.98; 95%CI: 1.70-5.05), and higher mortality (RR: 3.58; 95%CI: 2.39-5.28) than those without anemia. The rates of ischemic stroke (RR: 0.75; 95%CI: 0.23-1.93) and major bleeding (RR: 0.93; 95%CI: 0.15-3.51) were similar. On multivariable analysis, anemia was associated with an increased risk to die (hazard ratio [HR]: 2.32; 95%CI: 1.53-3.50) but not to develop MI (HR: 1.49; 95%CI: 0.73-3.05) or to have limb amputation (HR: 1.49; 95%CI: 0.86-2.59). In stable outpatients with PAD, anemia was associated with increased mortality but not with an increased rate of subsequent ischemic events or major bleeding. PMID:26271128

    Full Text Available INTRODUCTION AND OBJECTIVES : Anemia in Protein energy malnutrition (PEM is common and its pathogenesis is multifactorial. Since the clinico - pathological patterns are reflected by their underlying etiopathogenic factors, it is important to study the associated morbidity and mortalit y and to establish their causes for an effective management. The purpose of the present study is to determine the prevalence, patterns, clinico - pathological and morphological types of anemia in protein energy malnutrition children. The objectives of the st udy are: (1 To study the clinico - pathological and morphological patterns of anemia in PEM children of age group 6 month – 5 years. (2 To assess the resultant morbidity and mortality. (3 To determine the ideal parameter for iron deficiency anemia. METHOD S: This study was conducted on 75 clinically diagnosed Protein energy malnutrition patients of age group 6 months to 5 years. Detailed clinical history elicitation and thorough clinical examination was performed. Peripheral smears of these patients were ex amined. The complete hemogram including reticulocyte count was done. The special investigations like bone marrow study, Hb electrophoresis, iron studies and stool examination were done whenever required. RESULTS: In our study, anemia in PEM affected female population more than the males of age 36 - 47 months. Most of children had Grade III PEM and Microcytic hypochromic anemia was most prevalent. Most of the children had Iron deficiency anemia. This study also indicated that Serum iron assay and TIBC are the better indicators of iron deficiency anemia in patients with PEM and it is the investigation of choice when compared to serum ferritin as it gets falsely elevated in these patients with infections confirmed by elevated CRP level. INTERPRETATION AND CONCLUS ION: Malnutrition, Infection and Anemia show a synergistic relationship. So it necessitates prompt screening and early diagnosis through proper

    2011-11-01

    Anemia is a global public health problem. It has serious short- and long-term consequences during pregnancy and beyond. The anemic condition is often worsened by the presence of other chronic diseases such as malaria, tuberculosis, HIV, and diabetes. Untreated anemia also leads to increased morbidity and mortality from these chronic conditions as well. It is surprising that despite these chronic conditions (such as malaria, tuberculosis, and HIV) often being preventable, they still pose a real threat to public health. This article aims to review the current understanding of the pathophysiology, risks, prevention, and treatment of anemia in the light of these chronic conditions. PMID:22099433

    Full Text Available Sideroblastic anemia, comprising of acquired and congenital forms, is a heterogeneous group of disorders characterized by the presence of ring sideroblasts in the bone marrow. Congenital sideroblastic anemia is a rare condition which is mostly X-linked, caused by mutations of delta-aminolevulinic acid synthase 2. We describe two cases of congenital sideroblastic anemia, one of them indicating an autosomal recessive inheritance, with their clinico-hematological profile. It is important to recognize this entity early in life as a significant percentage of cases respond to pyridoxine thus avoiding any long-term complications.

  9. Assessing Chaos in Sickle Cell Anemia Crises

    Harris, Wesley; Le Floch, Francois

    2006-11-01

    Recent developments in sickle cell research and blood flow modeling allow for new interpretations of the sickle cell crises. With an appropriate set of theoretical and empirical equations describing the dynamics of the red cells in their environment, and the response of the capillaries to major changes in the rheology, a complete mathematical system has been derived. This system of equations is believed to be of major importance to provide new and significant insight into the causes of the disease and related crises. With simulations, it has been proven that the system transition from a periodic solution to a chaotic one, which illustrates the onset of crises from a regular blood flow synchronized with the heart beat. Moreover, the analysis of the effects of various physiological parameters exposes the potential to control chaotic solutions, which, in turn, could lead to the creation of new and more effective treatments for sickle cell anemia. .

    Proper management of sickle cell anemia (SCA) begins with establishing the correct diagnosis early in life, ideally during the newborn period. The identification of affected infants by neonatal screening programs allows early initiation of prophylactic penicillin and pneumococcal immunizations, which help prevent overwhelming sepsis. Ongoing education of families promotes the early recognition of disease-released complications, which allows prompt and appropriate medical evaluation and therapeutic intervention. Periodic evaluation by trained specialists helps provide comprehensive care, including transcranial Doppler examinations to identify children at risk for primary stroke, plus assessments for other parenchymal organ damage as patients become teens and adults. Treatment approaches that previously highlighted acute vaso-occlusive events are now evolving to the concept of preventive therapy. Liberalized use of blood transfusions and early consideration of hydroxyurea treatment represent a new treatment paradigm for SCA management. PMID:23709685

It is important for a general internist to identify pernicious anemia as one of the cause of pancytopenia and hemolytic anemia to avoid extensive workup. Pernicious anemia can present strictly with hematological abnormalities without neurological problems or vice versa as in our case. PMID:27609735

  17. Anemia in malignant disease. Pt. 2

    International Nuclear Information System (INIS)

    The cellular uptake and lysosomal accumulation of 67Ga-labelled transferrin within tumors of different malignancy were examined using tissue fractionation and immunological techniques. As tumor models the slowly growing Morris hepatoma 5123 C, the moderately growing Novikoff hepatoma and the fast and aggressive Yoshida hepatoma AH 130 were investigated. Isolation of subcellular fractions of tumor homogenates was performed by differential centrifucation and density-gradient centrifugation. The intracellular 67Ga-transferrin was found to be highly concentrated within the purified lysosomes. The transferrin within the lysosomal fraction was identified by radial immunodiffusion technique using monospecific antiserum. The accumulation of 67Ga-transferrin by the tumors resulted in a faster disappearance of 67Ga-transferrin from the blood. This loss of circulating 67Ga-transferrin correlated with the proliferation activity and the spread of the tumors. Since transferrin is indispensible for the utilization of iron by the heme-synthesizing red cell precursors, transferrin concentration in the blood is the limiting factor for the utilization of iron in hemoglobin synthesis. Thus, in a further series of experiments we investigated the development of anemia in tumor-bearing rats. With increasing tumor mass a progressive fall of hemoglobin concentration was found. The anemia was more severe in the faster growing Novikoff hepatoma than in the slowly growing Morris hepatoma. The most significant reduction of hemoglobin concentration was found in the very fast growing Yoshida hepatoma. After total tumor resection hemoglobin concentration and red blood cell count normalized completely within 6-8 weeks. We conclude from these data that the uptake of transferrin by the tumor cells results in a faster disappearance of transferrin from the blood. (orig./MG)

    Full Text Available A hipertensão pulmonar é uma complicação comum em pacientes com anemia falciforme. A despeito das elevações leves das pressões pulmonares desses pacientes, a morbimortalidade é alta e, em pacientes adultos com anemia falciforme, a hipertensão pulmonar é um fator de risco muito importante. A patogênese da hipertensão pulmonar relacionada à anemia falciforme é multifatorial e inclui hemólise, baixos níveis de óxido nítrico, hipóxia crônica, tromboembolismo, doença hepática crônica e asplenia. Na maioria dos pacientes, a hipertensão arterial pulmonar é a causa principal para as elevações na pressão arterial pulmonar, mas a hipertensão pulmonar venosa também é um fator contribuinte em alguns pacientes. Existem poucos estudos específicos avaliando os efeitos de tratamento para a hipertensão pulmonar em pacientes com anemia falciforme. É provável que a intensificação da terapia para a anemia hemolítica em todos os pacientes e o tratamento específico para a hipertensão pulmonar em pacientes com doença severa sejam benéficos. Estudos de grande porte avaliando o efeito do tratamento da hipertensão pulmonar em pacientes com anemia falciforme estão em andamento.Pulmonary hypertension is a common complication of sickle cell anemia. Despite the fact that the elevations in pulmonary artery pressures are slight, morbidity and mortality are high. In adult sickle cell anemia patients, pulmonary hypertension is emerging as a major risk factor for death. The pathogenesis of sickle cell anemia-related pulmonary hypertension is multifactorial, including hemolysis, impaired nitric oxide bioavailability, chronic hypoxemia, thromboembolism, chronic liver disease and asplenia. In the majority of patients, pulmonary arterial hypertension is the main cause of elevated pulmonary artery pressures. However, pulmonary venous hypertension also plays a role in a subgroup of patients. Specific data on the effects of treatment

  20. Epidemiological inference on induction of aplastic anemia following radiotherapy

    International Nuclear Information System (INIS)

    Some epidemiological inferences on possibility of induction of aplastic anemia following radiotherapy are tried. In Japan after 1969, there are detected and reported 11 cases of radiation-related aplastic anemia after radiotherapy diagnosed by hematologists. Of 11 cases, 2 are males and 9 are females, ranging 28 to 66 years of age. All these patients were irradiated for malignant diseases. The population at risk after 1969 was estimated to be 674, 660 man-years, based on the additional survey on number and survival rate of patients irradiated. The expected value of aplastic anemia calculated from this population at risk is 10.2, against 11 cases observed above-described. There is no statistically significant difference. Namely, there is no epidemiological evidence that aplastic anemia is induced by local-body irradiation such as radiotherapy. (auth.)

  1. Epidemiology of aplastic anemia in Japanese radiological technicians

    International Nuclear Information System (INIS)

    Among Japanese radiological technicians, four deaths from aplastic anemia have been recorded. Based on this fact, some epidemiological considerations are tried. 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. On the other hand, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been frequently induced among Japanese radiological technicians in the era when there was much exposure to occupational radiation. (auth.)

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the clinical presentation of aplastic anemia as well as to assess the efficacy of Cyclosporin -A in patients with aplastic anemia. This is a hospital based interventional study. During the three year study period, 44 children were enrolled. Mean age was 9.3 years and there was a male predominance. Most common clinical presentation was anemia and bleeding. Four children died before therapy was started. Cyclosporin-A was started in 40 patients. Eleven patients died before completion of therapy and three patients were lost to follow-up. Out of 26 patients who completed therapy, 11 were cured and 9 were responders while 6 were non responders according to the selected criteria. In developing third world countries like Pakistan majority of the patients with aplastic anemia cannot afford BMT. Alternative modalities of treatment must therefore be looked into. Cyclosporin-A seems to be a reasonable therapeutic option in such cases. (author)

Data were collected in indexed databases and academic bibliography. The sample composition criteria permitted the inclusion of texts on social inclusion and public inclusion policies. Data were analyzed according to Thematic Content Analysis. It is concluded that disabled people have conquered a policy that guarantees access to goods and services, but face difficulties to achieve inclusion in education and the job market, due to the lack of education, qualification and resistance strategies by companies that refuse to hire them. The academic discourse highlights social inclusion problems, prioritizing rights to education, jobs and health care, to the detriment of rights related to culture, tourism and leisure.Se busca investigar el impacto de la Política Nacional para la Integración de la Persona Portadora de Deficiencia en Brasil y qué aspectos de esa política están evidentes en el discurso académico.

    2005-01-01

    Over 3 million people in the United States aged 65 years and older are anemic. This condition is associated with significant functional impairment and, perhaps, increased mortality. In March 2004, the American Society of Hematology (in conjunction with the National Institute of Aging) convened a "blue ribbon" panel of twenty physicians who are experts on various aspects of this topic. This paper highlights important consensus concepts resulting from that meeting. In particular, four areas of thought are shared. First, the epidemiology of anemia in the elderly is reviewed, including its definition, its expression in different racial groups, and its wide-ranging manifestations. Second, the pathophysiology of anemia in the elderly is reviewed as pertains to three general etiological categories (nutritional, chronic diseases, and so-called "unexplained" anemias). Particular emphasis is given to pathophysiologic mechanisms of anemia that are potentially unique to this age group. Third, a practical approach to the diagnosis and management of anemia for this patient population for the practicing hematologist is provided. Finally, the public health implications of anemia in the elderly for key stakeholder constituencies will be discussed in the oral presentation. PMID:16304431

    2015-09-01

    The heterogeneous group of patients admitted to Intensive Cardiac Care Unit (ICCU) as well as nonspecific complaints associated with anemia might be the reason for underdiagnosing or minimization of this problem. Because of this heterogeneity, there are no clear guidelines to follow. It is known that anemia is impairing the outcome. Thus, it is crucial to keep alert in the diagnosis and treatment of anemia, especially in critically ill cardiac patients. The greatest groups of patients admitted to ICCU are those with acute coronary syndromes (ACS), acute decompensated heart failure (ADHF), severe arrhythmias as well as individuals after cardiac operations. However, patients suffering other critical cardiac illnesses quite often become anemic during hospitalization in ICCU. It is because anemia is typed in the clinical features of heavy diseases or may be the consequence of treatment. The current review focuses on the incidence, complex etiology and predictive role of anemia in a diverse group of ICCU patients. It discusses clinical aspects of anemia treatment in particular groups of critically ill cardiac patients because proper treatment increases chances for recovery and improves the outcome in this severe group of patients.

    Full Text Available Anemia is one of the most frequent complications and/or extraintestinal manifestations of inflammatory bowel disease (IBD. Iron deficiency is the most important cause of anemia in Crohn’s disease and ulcerative colitis patients. Iron deficiency even without anemia may impact the quality of life of our IBD patients. In the last ten years the understanding of the pathophysiology of iron deficiency anemia and anemia of chronic diseases has increased, new diagnostic tools have been developed and new therapeutic strategies have been discussed. Hepcidin has been identified to be a central regulator of iron absorption from the intestine and of iron plasma levels. Hepcidin is regulated by iron deficiency but also as an acute phase protein by pro-inflammatory mediators such as interleukin-6. Innovative diagnostic tools with respect to iron metabolism have not been introduced in clinical routine or are not available for routine diagnostics. As iron substitution therapy is easy these days with a preference for intravenous substitution the impact of differential diagnosis of anemia in IBD patients is underestimated.

    Full Text Available The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases, with particular reference to anemias and disorders of hemostasis. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases, with emphasis on anemia. Mesh phrases used in the search were: oral diseases AND anaemia; orofacial diseases AND anaemia; orofacial lesions AND anaemia; orofacial manifestations AND disorders of haemostasis. The Boolean operator "AND" was used to combine and narrow the searches. Anemic disorders associated with orofacial signs and symptoms include iron deficiency anemia, Plummer-Vinson syndrome, megaloblastic anemia, sickle cell anemia, thalassaemia and aplastic anemia. The manifestations include conjunctiva and facial pallor, atrophic glossitis, angular stomatitis, dysphagia, magenta tongue, midfacial overgrowth, osteoclerosis, osteomyelitis and paraesthesia/anesthesia of the mental nerve. Orofacial petechiae, conjunctivae hemorrhage, nose-bleeding, spontaneous and post-traumatic gingival hemorrhage and prolonged post-extraction bleeding are common orofacial manifestations of inherited hemostatic disorders such as von Willebrand′s disease and hemophilia. A wide array of anemic and hemostatic disorders encountered in internal medicine has manifestations in the oral cavity and the facial region. Most of these manifestations are non-specific, but should alert the hematologist and the dental surgeon to the possibilities of a concurrent disease of hemopoiesis or hemostasis or a latent one that may subsequently manifest itself.

    Full Text Available In some renal allograft recipients, anemia persists or develops following transplantation. Anemia is associated with pre-operative blood loss and allograft dysfunction, including delayed graft function, acute rejection and chronic allograft dysfunction. To study the prevalence and association of post-renal transplant anemia, we studied 200 renal transplant recipients; 131 (65.5% patients were males and 69 (34.5% patients were females, and age ranged from 17 to 67 years, with a mean of 37.7 ± 10.8 years. All patients were receiving cyclosporine, prednisolone and mycophenolate mofetil (MMF. Complete blood count was done at two times: three and six months post-renal transplant. There were 74% anemic patients three months after renal transplantation and 45% anemic patients six months after renal transplantation. High creatinine value, female gender, delayed graft function, episodes of acute rejection, perioperative blood loss and infections were the only significant independent risk factors for prevalence of anemia post-renal transplant. In our study, we did not find an association between MMF and cyclosporine nor angiotensin-converting enzyme inhibitors (ACEIs or angiotensin receptors blocker (ARBs with anemia. This study demonstrates that anemia is a common complication during the first six months after kidney transplantation, with several risk factors precipitating this complication.

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

    BACKGROUND: Management of patients with autoimmune hemolytic anemia (AIHA) and reticulocytopenia remains challenging. CASE REPORTS: Two patients with decompensated AIHA who were receiving immunosuppressive drugs were treated with erythropoietin (EPO). Administration of EPO increased reticulocyte counts and hemoglobin concentrations in both cases. One patient completely recovered following a short course of treatment. Hemolysis could be compensated in the second patient using only mild doses of immunosuppressive drugs in combination with EPO. CONCLUSION: The administration of EPO should be considered in patients with therapy-refractory AIHA, particularly in the presence of reticulocytopenia. PMID:22851939

  3. Genetic/metabolic effect of iron metabolism and rare anemias

    Full Text Available Advances in iron metabolism have allowed a novel classification of iron disorders and to identify previously unknown diseases. These disorders include genetic iron overload (hemochromatosis and inherited iron-related anemias, in some cases accompanied by iron overload. Rare inherited anemias may affect the hepcidin pathway, iron absorption, transport, utilization and recycling. Among the genetic iron-related anemias the most common form is likely the iron-refractory iron-deficiency anemia (IRIDA, due to mutations of the hepcidin inhibitor TMPRSS6 encoding the serine protease matriptase-2. IRIDA is characterized by hepcidin up-regulation, decrease iron absorption and macrophage recycling and by microcytic- hypochromic anemia, unresponsive to oral iron. High serum hepcidin levels may suggest the diagnosis, which requires demonstrating the causal TMPRSS6 mutations by gene sequencing. Other rare microcytic hypochromic anemias associated with defects of iron transport-uptake are the rare hypotransferrinemia, and DMT1 and STEAP3 mutations. The degree of anemia is variable and accompanied by secondary iron overload even in the absence of blood transfusions. This is due to the iron-deficient or expanded erythropoiesis that inhibits hepcidin transcription, increases iron absorption, through the erythroid regulator, as in untransfused beta-thalassemia. Sideroblastic anemias are due to decreased mitochondrial iron utilization for heme or sulfur cluster synthesis. Their diagnosis requires demonstrating ringed sideroblasts by Perl’s staining of the bone marrow smears. The commonest X-linked form is due to deltaamino- levulinic-synthase-2-acid (ALAS2 mutations. The recessive, more severe form, affects SLC25A38, which encodes a potential mitochondrial importer of glycine, an amino acid essential for ALA synthesis and thus results in heme deficiency. Two disorders affect iron/sulfur cluster biogenesis: deficiency of the ATP-binding cassette B7 (ABCB7 causes X

    2016-02-01

    The major causes of iron deficiency anemia (IDA) include iron loss due to bleeding, increased iron requirements, and decreased iron absorption by the intestine. The most common cause of IDA in Japanese women is iron loss during menstruation. Autoimmune atrophic gastritis and Helicobacter pylori infection can also cause IDA by reducing intestinal iron absorption. In addition to these common etiologies, germline mutations of TMPRSS6 can cause iron-refractory IDA (IRIDA). TMPRSS6 encodes matriptase-2, a membrane-bound serine protease primarily expressed in the liver. Functional loss of matriptase-2 due to homozygous mutations results in an increase in the expression of hepcidin, which is the key regulator of systemic iron homeostasis. The serum hepcidin increase in turn leads to a decrease in iron supply from the intestine and macrophages to erythropoietic cells. IRIDA is microcytic and hypochromic, but decreased serum ferritin is not observed as in IDA. IRIDA is refractory to oral iron supplementation, but does respond to intravenous iron supplementation to some extent. Because genetic testing is required for the diagnoses of IRIDA, a considerable number of cases may go undiagnosed and may thus be overlooked. PMID:26935626

  7. Fanconi anemia proteins and endogenous stresses

    International Nuclear Information System (INIS)

    Each of the thirteen identified Fanconi anemia (FA) genes is required for resistance to DNA interstrand crosslinking agents, such as mitomycin C, cisplatin, and melphalan. While these agents are excellent tools for understanding the function of FA proteins in DNA repair, it is uncertain whether a defect in the removal of DNA interstrand crosslinks (ICLs) is the basis for the pathophysiology of FA. For example, DNA interstrand crosslinking agents induce other types of DNA damage, in addition to ICLs. Further, other DNA-damaging agents, such as ionizing or ultraviolet radiation, activate the FA pathway, leading to monoubiquitination of FANCD2 and FANCI. Also, FA patients display congenital abnormalities, hematologic deficiencies, and a predisposition to cancer in the absence of an environmental source of ICLs that is external to cells. Here we consider potential sources of endogenous DNA damage, or endogenous stresses, to which FA proteins may respond. These include ICLs formed by products of lipid peroxidation, and other forms of oxidative DNA damage. FA proteins may also potentially respond to telomere shortening or replication stress. Defining these endogenous sources of DNA damage or stresses is critical for understanding the pathogenesis of deficiencies for FA proteins. We propose that FA proteins are centrally involved in the response to replication stress, including replication stress arising from oxidative DNA damage.

    Full Text Available Dog poisoning toxicant used at home for rodent control (often based on zinc phosphide is accompanied by the development of anemia . In etiopathogenesis of this type of pathology of the blood we can highlight as important: haemolytic , haemorrhagic and allergic components, but the nature and extent of the changes under there are unequal. This requires the development of a special algorithm of examination and treatment strategies of the animal in accordance with the stages of the development of the disease. Modern conditions dictate the need, along with the actions to carry out urgent medical identification as the main etiological factor and pathogenesis, and the leading pathogenetic factors that pose a threat to the danger of other pathological processes and disease states. First, we evaluate the extent of damage to the liver, kidneys, heart, spleen and blood vessels, which is possible only if the clinic has appropriate methods and equipment. It is undeniable in this regard the importance of evidence-based recommendations for dietary nutrition of the affected animal's behavior after the clinic urgent remedial measures. The article proves high importance of evaluating the effectiveness of the treatment in the clinic

    Valdez, Jessica M; Scheinberg, Phillip; Young, Neal S; Walsh, Thomas J

    2009-07-01

    Infection is a major cause of death in patients with aplastic anemia (AA). There are differences between the immunocompromised state of a patient with AA and the patient who is neutropenic due to chemotherapy and this leads to a difference in the infections that they incur. Prolonged neutropenia is one of the largest risk factors for the development of infections with the invasive mycoses and bacteria. Recovery from neutropenia is directly related to survival, and supportive care plays a large role in protection while the patient is in a neutropenic state. The most common invasive mycoses include the Aspergillus species, Zygomycetes, Candida spp., and Fusarium spp. Bacterial infections that are seen in patients with AA include gram-positive coagulase-negative Staphylococcus species, Enterococcus, Staphylococus aureus, Clostridium spp., Micrococcus, alpha-hemolytic streptococci, Listeria monocytogenes, and Bacillus cereus. Gram-negative infections including gram-negative bacilli, Escherichia coli, Salmonella, Bacteroides fragilis, Klebsiella oxytoca, Klebsiella pneumonia, Aeromonas hydrophilia, Pseudomonas aeruginosa, and Vibrio vulnificus. Viral infections are much less common but include those that belong to the Herpesviridae family, community-acquired respiratory viral infection, and the viral hepatitides A, B, and C. Evidence of the parasite Strongyloides stercoralis has also been documented. This review discusses the major invasive fungal infections, bacterial pathogens, parasites, and viral infections that are found in patients with AA who are treated with immunosuppressive therapy. The specific immune impairment and current treatment parameters for each of these classes of infection will also be discussed. PMID:19549579

    Full Text Available INTRODUCTION: Sideropenic anemia is one of the most common nutritional disorders in the world. The children are at higher risk of iron deficiency than adults due to their rapid growth during infancy and relatively higher requirements of iron. OBJECTIVE: The objective of our study was to investigate the prevalence of sideropenic anemia in pre-school children and relevant risk factors. METHOD: Study on sideropenic anemia of preschool children was performed in Zaječar Municipality in 2003. Subjects: all children, age 6-7 years, who lived in the Zaječar Municipality (554 children. The investigation included: interview of children's parents and laboratory analysis of blood. RESULTS: The frequency of sideropenic anemia was 5.23% in tested children (hemoglobin level less than 11g/dl. Sex and place of residence had no significant impact on hemoglobin concentration in blood of children. Likewise, social status and education of parents had no significant impact on iron deficiency anemia. Higher incidence of infections was found in children with lower hemoglobin concentration in blood (p<0.05. It made no difference if children attended the kindergarten or not. Nutrition of children in kindergarten does not correct domestic nutrition, which should be one of its basic roles. CONCLUSION: Since sideropenic anemia gives rise to serious health problems, such as poor cognitive and motor development and behavioral problems, it is important to take corrective measures regarding domestic and social nutrition of children. Therefore, it is necessary to take action in preventing the sideropenic anemia and provide normal growth and development.

AIMS AND OBJECTIVE: Evaluation of hemoglobin improvement, time required, and patient’s compliance after iron sucrose therapy. MATERIAL AND METHODS: Retrospective analysis was done of 264 pregnant women with anemia who were admitted in R. D. Gardi Medical College Ujjain M. P. from M ay 2012 to August 2014, and were diagnosed as iron deficiency anemia and had received intravenous iron sucrose 200 mg weekly till targeted hemoglobin 10gm was reached. RESULTS: majority of women (54.2% were in age group of 21 - 29 years. 66.3% were resident of rural area. Anemia was more common (69.7% in women with vegetarian diet. 83% 0f patients were multigravida. 48.9% cases were of mild, 44.7% of moderate, and 6.4 % of severe anemia. There was initial rise in Hb within a week and rise of 1 - 2gm Hb per week attaining a targeted Hb. CONCLUSION: Iron sucrose is the best tolerated drug, gives mean Hb rise by 600 mg in all grades of anemia and in maximum periods of 4 weeks. Looking at the patient’s compliance and feasibility this drug has replaced strategy of unnecessary blood transfusions.

    Full Text Available A anemia na insuficiência renal crônica deve-se à redução da produção de eritropoetina, devido à diminuição da massa renal funcionante. A eritropoetina tem sido preconizada para o tratamento da anemia, no entanto, cerca de 5% dos pacientes são resistentes à mesma. A resistência à eritropoetina é definida como a necessidade do uso de uma dose maior que 12.000U/kg por semana, sem atingir o hematócrito alvo de 33% a 36%. As citocinas pró-inflamatórias têm uma associação importante com a anemia resistente ao tratamento com eritropoetina (EPO. A pentoxifilina tem sido usada para inibir a produção dessas citocinas pró-inflamatórias. Este estudo foi realizado com os pacientes sob hemodiálise no Instituto de Nefrologia Ribamar Vaz, do Hospital da Santa Casa de Misericórdia de Maceió-Al. Os pacientes com diagnóstico de resistência à eritropoetina receberam pentoxifilina na dose de 400 mg VO, após hemodiálise por seis meses. Avaliamos o hematócrito e a proteína C reativa (PCR em dois momentos: ao final de três meses com 12 pacientes e, ao final de seis meses, com sete pacientes. A média de PCR dos 12 pacientes, no primeiro mês, foi de 5,65 mg/l. No terceiro mês, de 2,58 mg/l. Porém, no sexto mês, considerando apenas os sete que terminaram o projeto, foi de 4,55 mg/l. Não foi observada diferença significativa. A média final dos hematócritos(Htc observada nos pacientes foi de 28,74 %. A média dos Htc na avaliação de seis meses que precederam o início do projeto, foi de 26,22%. Não foi observada diferença estatisticamente significante, quer nos 12 pacientes acompanhados por três meses ou nos sete que conseguiram concluir o estudo. Não observamos correlação entre os níveis de PCR e os de hematócrito. No entanto, em nossa amostragem, a média de PCR basal não estava elevada e este pode ter sido um fator importante nos resultados díspares em relação aos dados da literatura. Sendo assim, conclu

    Full Text Available Apesar de a anemia falciforme ser a doença hereditária de maior prevalência no Brasil, a literatura nacional carece de investigações a respeito dos seus aspectos de Saúde Pública. Investigou-se a realidade vivida por 80 pacientes adultos (49 mulheres e 31 homens com diagnóstico de anemia falciforme, seguidos regularmente em centro hematológico. O diagnóstico tardio da doença foi um dos principais aspectos detectados na casuística examinada. Observou-se que a problemática maior do paciente adulto com a anemia falciforme esta centrada nos aspectos econômicos, sobretudo na falta de oportunidades profissionais, apesar de os mesmos poderem participar do mercado de trabalho, desde que estejam recebendo tratamento médico adequado e exerçam funções compatíveis com as suas limitações e potencialidades. A orientação psicoterapêutica teve uma grande aceitação pelos pacientes, sem diferença significativa entre os sexos. Concluiu-se haver necessidade da implantação de programas comunitários de diagnóstico precoce e de orientação médica, social e psicológica dos doentes com a anemia falciforme no Brasil, bem como de aconselhamento genético não diretivo dos casais de heterozigotos com o traço falciforme.Sickle cell anemia is the most prevalent hereditary disease in Brazil. However, the Brazilian literature registers no investigations into the public health aspects of the disease. This present study investigates the way of life of 80 adult patients (49 women and 31 men with a diagnosis of sicklecell anemia, at a blood center in Brazil. The late diagnosis of the disease was one of the most significant aspects observed in this group of patients. It was also observed that the dominant problem faced by adult patients with sickle cell anemia is of an economic nature, mainly due to lack of professional opportunities. However, patients can well undertake economic activities under adequate medical supervision, according to their

    Full Text Available Con el objetivo de determinar el impacto de la administración con multimicronutrientes (MMN en polvo sobre la anemia infantil en tres regiones andinas del Perú, se estableció un sistema de vigilancia centinela en 29 establecimientos de Andahuaylas, Ayacucho y Huancavelica, en niños de 6 a 35 meses de edad, a quienes se les indicó MMN por un periodo de 12 meses, entre el 2009 y 2011. Además de los datos sociodemográficos de los menores y las madres, se determinó los niveles de hemoglobina al inicio y al final del estudio. Entre los menores que culminaron la suplementación, la prevalencia de anemia se redujo de 70,2 a 36,6% (p<0,01, y se evidenció que el 55,0% y el 69,1% de niños con anemia leve y moderada al inicio del estudio, la habían superado al término del mismo. Se concluye que la suplementación con MMN en polvo puede ser una estrategia efectiva en la lucha contra la anemia.

    Willebrand y HIV positiva sometida a cesárea. RELATO DEL CASO: Paciente de 24 años, portadora de anemia microcítica, enfermedad de von Willebrand y HIV, llegó a la emergencia obstétrica en inicio de trabajo de alumbramiento. No realizó prenatal. Fue indicada cesárea a fin de disminuir los riesgos de transmisión vertical en paciente con carga vírica de HIV desconocida. Presentaba hematomas por el cuerpo e historia de hematoma de pared abdominal en cesárea anterior. Los tests de coagulación estaban un poco alterados. Después de infusión de concentrado de factor VIII fue realizada anestesia general. Madre y recién nacido presentaron evolución satisfactoria. CONCLUSIONES: La evaluación de manifestaciones clínicas en pacientes con coagulopatia es fundamental en la decisión del tipo de anestesia que será indicada para cada paciente. La evaluación debe ser individualizada, considerando los riesgos y beneficios de la técnica escogida. En estas pacientes, se debe siempre restringir al máximo la indicación de interrupción de la gestación por vía alta, optándose siempre por los métodos menos invasivos. La terapia con concentrado de factor VIII es actualmente la mejor opción de tratamiento, corrigiendo la deficiencia específica y dismunuyendo los riesgos de transmisión vírica.BACKGROUND AND OBJECTIVES: Von Willebrand's disease is the most common hereditary coagulation disorder in young women. The incidence of HIV infection among women has been progressively increasing, and vertical transmission may account for 25% of cases. This report aimed at describing the case of an HIV-positive patient with von Willebrand's disease scheduled for cesarean section. CASE REPORT: Female HIV-positive patient, 24 years old, with microcytic anemia and von Willebrand's disease, admitted to the emergency room in early labor. She had no pre-natal care. Cesarean section was indicated to lower vertical transmission risks since HIV viral count was unknown. Patient had hematomas
