Full Text Available The treatment of iron deficiency anemia in children usually consists in the use of ferrous sulfate solution, but this treatment does not always have the desired effectiveness. The aim of this study was to evaluate the effectiveness of chewable carbonyl iron tablets as an alternative for the treatment of iron deficiency anemia in under six-year-old children. Seventy-three children from Brazilian Family Health Units in Santa Maria, Brazil, were included in this study. One group received chewable carbonyl iron (CI tablets and a control group received a solution of ferrous sulfate (FS for 90 days, both at a dose of 5 mg/Kg/day. Blood was drawn from study participants at 0, 30 and 90 days of treatment to evaluate the whole blood test, ferritin concentration, serum iron, and total iron binding capacity. We also evaluated the acceptance and adherence to treatment, and the occurrence of side effects during treatment. Hemoglobin increased 1.3 g/dL in the CI Group and 1.2 g/dL in the FS group during the first 30 days of treatment. After 90 days of treatment, the CI Group had significantly better results for hematocrit, MCV, MCH, iron binding capacity and ferritin concentration compared to the FS Group. The ferritin concentration was significantly higher in the CI Group at the end of the treatment (9.51 ng/mL to 26.16 ng/mL. Additionally, the treatment was better accepted with fewer adverse effects by this group. Chewable carbonyl iron tablets should be considered an important therapeutic option in the treatment of iron deficiency anemia of under six-year-old children.O tratamento da anemia ferropriva de crianças consiste, em sua maioria, no uso de solução de sulfato ferroso e este tratamento nem sempre apresenta a efetividade desejada.

A concentração de hemoglobina foi medida com hemoglobinômetro portátil, HemoCue e anemia foi definida como valores de hemoglobina OBJECTIVE: To assess the prevalence of anemia among children under six years of age in a probabilistic sample from an urban area. METHODS: A study was conducted comprising children aged zero to five years in the city of Pelotas, Southern Brazil, in 2004. Data were collected on demographic, socioeconomic, and anthropometric characteristics, morbidity and nutrition using a questionnaire applied to the mothers and guardians. Children's weight and height measurements were obtained. Hemoglobin concentration was measured using the HemoCue portable hemoglobinometer and anemia was defined as hemoglobin <11 g/dL. The association between anemia and predictors was expressed as prevalence ratio. Multivariate analysis was carried out using Poisson regression following a conceptual model and taking into account the study design effect. RESULTS: There were identified 534 children and total losses and refusals were 27 (5.1%. The prevalence of anemia was 30.2% (95% CI 23.5%;37.0%. In the multivariate analysis, only age and family income remained significantly associated with anemia. CONCLUSIONS: Anemia was largely socially determined in the population studied. Interventions aiming at reducing anemia should be developed to lessen this condition in the short run targeting disadvantaged populations.

Full Text Available Observou-se a eficácia da fortificação do leite fluido com 3 mg de ferro aminoácido quelato no combate à carência de ferro em crianças menores de quatro anos. Foram acompanhadas 269 crianças que receberam, durante 12 meses, um litro de leite fortificado por dia, e que foram avaliadas a cada 6 meses de acompanhamento. Antes de se iniciar a intervenção, a anemia estava presente em 62,3% das crianças. Após 6 meses, este percentual reduziu-se a 41,8% e, ao final de um ano, a 26,4%. As maiores reduções foram detectadas nas faixas etárias de 12 a 23 meses e em menores de um ano. Das crianças que apresentavam hemoglobinas iniciais inferiores a 9,5 g/dl, 59,3% recuperaram-se da anemia ao final de um ano de acompanhamento. Naquelas com hemoglobinas iniciais entre 9,5 e 10,9 g/dl, o percentual de recuperação da anemia foi de 66,7%. Encontrou-se, ainda, melhores evoluções hematológicas em crianças que ingeriam quantidades superiores a 750 ml/dia de leite fortificado, pertencentes a famílias que não dividiam o suplemento recebido com outros membros e naquelas com apenas uma criança com menos de 5 anos no núcleo familiar. Concluiu-se pela viabilidade e eficácia da fortificação do leite fluido como medida de intervenção no combate à carência de ferro em pré-escolares.The effectiveness of the use of chelate aminoacid iron fortified fluid milk in the treatment of iron deficiency in children under four years of age was studied.

Full Text Available A adolescência constitui etapa de risco para o desenvolvimento da anemia ferropriva, uma vez que ocorre aumento da necessidade de ferro decorrente do crescimento estatural e da maturação biológica. Estudaram-se 130 adolescentes, de ambos os sexos, para verificar os valores de hemoglobina sérica em diferentes fases de maturação sexual. Utilizou-se o método de fotometria para dosar a hemoglobina sérica e realizou-se auto-avaliação do estágio de maturação sexual com base nos critérios de Tanner. Os níveis médios de hemoglobina foram semelhantes entre sexos, bem como entre meninas que menstruavam ou não. O nível médio de hemoglobina foi de 13,3g/dL tanto para os meninos como para as meninas (p=0,64, com desvios-padrão de 1,12 e de 0,83, respectivamente. Entre os adolescentes estudados, 7,7% tinham anemia ferropriva. Recomenda-se atenção ao grupo de adolescentes, devido ao aumento da necessidade de ferro durante o estirão de crescimento, principalmente entre as meninas, aumentando a suscetibilidade à anemia.During adolescence, the risk of development of iron-deficiency anemia is higher because of the growth spurt and the sexual maturation which increase the iron requirement. One hundred and thirty adolescents (males and females were studied, in order to assess the serum hemoglobin values in different sexual maturation stages. The photometric method was used and a self-evaluation of the sexual maturation stage based on Tanner's criteria was applied. The average hemoglobin values were similar for both sexes, as well for girls who had menstruated or not. The average hemoglobin values were 13.3 (s.d. 1.12g/dL for males and 13.3 (s.d. 0.83g/dL for females (p=0.64. Among the studied adolescents, 7.7% had iron-deficiency anemia. Due to the iron requirement increase during the growth spurt, mainly in females, and the higher susceptibility to iron deficiency anemia, special attention to the adolescents is recommended.

O objetivo deste trabalho foi estimar a prevalência e características da anemia em idosos do Programa de Saúde da Família de Camaragibe, PE. O delineamento foi transversal, com amostra aleatória sistemática de 284 idosos > 60 anos, de ambos os sexos, realizado em novembro/dezembro-2003. A anemia foi avaliada pela hemoglobina (Hb, concentração de hemoglobina corpuscular média (CHCM, volume corpuscular médio (VCM e amplitude de distribuição eritrocitária (RDW. A prevalência de anemia foi, em média, de 11,0%. A morfologia eritrocitária não mostrou associação com as concentrações de Hb. A grande maioria dos idosos apresentou anemia normocrômica, normocítica, sem anisocitose, sugestivo de anemia por doença crônica. A ínfima prevalência de microcitose e macrocitose com anisocitoseminimiza a gênese da deficiência de ferro, bem como da deficiência de vitamina B12 e ácido fólico na etiologia da anemia em idosos. Concluímos que o uso de indicadores que reflitam o grau de anisocitose eritrocitária associados àqueles que avaliam o estado nutricional do ferro é extremamente recomendado para o diagnóstico das anemias em idosos.Anemia is a serious public health problem worldwide that mainly affects children and women of childbearing age.

MÉTODOS: Estudo transversal com dados da III Pesquisa Estadual de Saúde e Nutrição/Pernambuco em amostra representativa de 1.403 crianças para as áreas urbana e rural. A anemia foi diagnosticada pela dosagem da hemoglobina. A análise multivariada foi realizada a partir de um modelo hierárquico, utilizando a regressão de Poisson, com variância robusta para estimar a razão de prevalência em função de variáveis: biológicas, de morbidade e estado nutricional da criança, socioeconômicas, de habitação, de saneamento e fatores maternos. RESULTADOS: A prevalência ponderada de anemia foi de 32,8%: 31,5% na área urbana e 36,6% na rural. Na área urbana, as variáveis que se associaram significantemente à anemia foram: escolaridade materna, bens de consumo, número de crianças menores de cinco anos no domicílio, tratamento da água de beber, idade e anemia materna e idade da criança. Na área rural, apenas a idade materna e a idade da criança associaram-se de modo significante à anemia. CONCLUSÕES: A prevalência de anemia nas crianças pernambucanas é semelhante nas áreas urbana e rural. Os fatores associados à anemia apresentados devem ser considerados no planejamento de medidas efetivas para o seu controle.

Full Text Available Para estabelecer a freqüência de hemoglobinopatias e talassemias em pacientes com anemia não ferropênica foram estudados 58 casos de pacientes comprovadamente com anemia não ferropênica e 235 controles obtidos de pessoas sem anemia. Todas as amostras foram obtidas do Hospital de Clínicas de Porto Alegre (HCPA, RS, Brasil. As técnicas realizadas foram eletroforese em acetato de celulose, pH alcalino, pesquisa citológica de Hb H, HPLC, hemograma e ferritina. A análise dos dados realizada no grupo de pacientes com anemia não ferropênica demonstrou que 63,8% eram portadores de alguma forma de anemia hereditária: 25,9% de talassemia alfa heterozigota, 32,8% de talassemia beta heterozigota, 3,4% de heterozigose para hemoglobina S (Hb AS e 1,7% de homozigose para hemoglobina C (Hb CC. No grupo dos controles, foram identificados 14,1% de anemias hereditárias, sendo destas 11,5% de talassemia alfa, 0,9% de talassemia beta, 1,3% de heterozigose para hemoglobina S (Hb AS e 0,4% de heterozigose para hemoglobina C (Hb AC. Os resultados obtidos permitem concluir que a prevalência de talassemias e hemoglobinas variantes no grupo controle é coincidente com a descrita na literatura. Entretanto, a excepcional prevalência dessas hemopatias hereditárias em pessoas com anemia não ferropênica deve ser divulgada entre médicos e serviços de saúde dada a sua importância no diagnóstico definitivo de anemia e dos corretos procedimentos terapêuticos.To establish the frequency of hemoglobinopathies and thalassemias in patients with non-ferropenic anemia, 58 patients with confirmed non-ferropenic anemia and 235 non-anemic individuals (control group were studied.

Full Text Available Foram estudados 10 doentes, portadores de anemia ancilostomótica e de grande parasitose. Foram determinados alguns parâmetros hematológicos como dosagem de hemoglobina, contagem de hemácias, hematócrito, volume corpuscular médio, hemoglobina corpuscular média, ferro sérico e siderofilina. Foram estudados o volume da perda de sangue intestinal, o ferro perdido nesta hemorragia e eliminado nas fezes, e o ferro reaborvido da hemorragia intestinal. Conclui-se que a reabsorção do ferro da hemoglobina por dia no tubo digestivo é de suma importância no retardamento da instalação da anemia ferropriva, causada pela parasitose ancilostomótica.Ten patients presenting ancylostomotic anemia and a high rate of parasitosis were submitted to several hematologic determinations: hemoglobin level, erythrocyte count, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, serum iron level, and transferrin. In addition, measurements were made of the blood volume lost by intestinal bleeding, of iron loss through hemorrhage and in feus, and of iron reabsorption from intestinal bleeding. The main reason for the late appearance of iron deficiency anemia in ancylostomiasis is the high degree of dally iron absorption in the digestive tract, originating from hemoglobin breakdown.

Full Text Available FUNDAMENTO: O levosimendan é conhecido pelo seu efeito bilateral de fortalecimento contração das miofibrilas sem aumentar a demanda de oxigênio no miocárdio. A anemia é uma deterioração que causa aumento da dosagem de fármacos em pacientes com insuficiência cardíaca. OBJETIVO: No presente estudo comparamos a eficácia do tratamento com levosimendan em pacientes com insuficiência cardíaca descompensada com ou sem anemia. MÉTODOS: Foram incluídos no estudo 23 pacientes anêmicos com insuficiência cardíaca classe 3 ou 4, segundo a New York Heart Association (NYHA e fração de ejeção abaixo de 35%. Outros 23 pacientes com o mesmo diagnóstico cardíaco, mas sem anemia, serviu como grupo controle. Ao tratamento da insuficiência cardíaca tradicional desses pacientes foi acrescido um tratamento de 24 horas de levosimendan. Amostras foram tomadas para dosar os níveis séricos do fator de necrose tumoral alfa sérico (TNF-alfa, peptídeo natriurético cerebral aminoterminal (NT-proPNB e metaloproteinase da matriz 1 (MMP-1, antes e após a administração. RESULTADOS: Não houve diferença significativa entre os níveis séricos de TNF-alfa e MMP-1, antes e depois do tratamento (p > 0,05. Embora o nível de NT-proBNP tenha diminuído em ambos os grupos após o tratamento, não foi estatisticamente significativo (p = 0,531 e p = 0,913 para os grupos de anemia e de controle, respectivamente. Uma restauração significativa da capacidade funcional foi observada em ambos os grupos avaliados, de acordo com a NYHA (p < 0,001 e p = 0,001 para os grupos de anemia e controle, respectivamente. CONCLUSÃO: O tratamento com levosimendan apresenta efeitos semelhantes em pacientes com insuficiência cardíaca, com anemia e sem anemia. No entanto, o efeito precoce desse tratamento sobre os níveis de TNF-alfa, NT-proPNB e MMP-1 não é evidente. Ele oferece uma melhora significativa na capacidade funcional, sem a influência da anemia.

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

O fluxo aéreo pode estar diminuído ou completamente interrompido, a despeito do esforço inspiratório, resultando em episódios intermitentes de hipoxemia, hipercapnia. A presença de SAOS poderá ser um fator de piora da hipoxemia noturna, da doença de base, concorrendo para ocorrência de síndrome torácica aguda. Com o objetivo de revisar dados sobre a fisiopatologia da SAOS em crianças e adolescentes portadores de anemia falciforme, foi realizada busca eletrônica de artigos no Medline e Lilacs nos últimos dez anos, bem como referências cruzadas dos artigos encontrados.

Dados retrospectivos foram obtidos de 12.119 prontuários de gestantes distribuídas em dois grupos: antes da fortificação, com parto anterior a junho de 2004, e após a fortificação, com última menstruação após junho de 2005. Anemia foi definida como Hb < 11,0 g/dL. Valores de Hb/idade gestacional foram avaliados segundo dois referenciais da literatura. Foram utilizados teste qui-quadrado, t de Student e regressão logística, com nível de 5% de significância. RESULTADOS: Na amostra total, anemia caiu de 25% para 20% após fortificação (p < 0,001, com médias de Hb significativamente maiores no grupo "após" (p < 0,001. Observaram-se, entretanto, diferenças regionais importantes: reduções significativas nas regiões Nordeste (37% para 29% e Norte (32% para 25%, onde as prevalências de anemia eram elevadas antes da fortificação, e reduções menores nas regiões Sudeste (18% para 15% e Sul (7% para 6%, onde as prevalências eram baixas. Os níveis de Hb/idade gestacional de ambos os grupos se mostraram discretamente mais elevados nos primeiros meses, porém bem mais baixos após o terceiro ou quarto mês, dependendo da referência utilizada para comparação. Análise de regressão logística mostrou que grupo, região geográfica, situação conjugal, trimestre gestacional, estado nutricional inicial e gestação anterior associaram-se com anemia (p < 0,05. CONCLUSÕES: A prevalência de anemia diminuiu após a fortificação, porém continua elevada nas regiões Nordeste e Norte. Embora a fortificação possa ter tido papel nesse resultado favorável, há que se considerar a contribuição de outras políticas p

El análisis de los resultados mostró que es normal encontrar hasta un 4,3 % de microcitosis y un 4,3 % de hipocromía en niños sin anemia, y cifras superiores a éstas en niños con anemia. En todos los casos estudiados se demostró que la causa de la hipocromía y de la microcitosis fue el déficit de hierro. Resultó evidente que la palidez cutáneo-mucosa, la astenia y la anorexia fueron los elementos clínicos más frecuentemente encontrados, mientras que la esplenomegalia no fue tan frecuente como se plantea. El análisis de la extensión de sangre teñida constituye un parámetro eficaz para el diagnóstico. Se insiste en la divulgación del método y en la aplicación en el diagnóstico de la anemia ferropénica

METHOD: This cross-sectional study included 2 715 infants between 6 and 12 months old in 12 cities, in all five of the geographic regions of Brazil. Information regarding the child and its feeding habits was obtained from the mother or other caregiver, using a questionnaire. Nutritional status was determined based on height and weight measurements. The hemoglobin concentration was measured using the HemoCue portable hemoglobinometer. Anemia was defined as hemoglobin < 11 g/dL. The infants’ eating habits were assessed based on what they were eating around the time of the questionnaire interviews. The association between anemia and the different variables was evaluated through bivariate analysis, followed by multiple logistic regression using a hierarchical selection model.

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.

Full Text Available Apesar do diagnóstico da anemia infecciosa e mais evidências recentes de infecção em campo (Brentano & Ottati, 1999, não havia até hoje dados disponíveis da prevalência do vírus da anemia das galinhas (CAV no Brasil. Uma vez que o conhecimento da prevalência do vírus e da distribuição de anticorpos nos lotes de matrizes é essencial para o delineamento de estratégias de controle da doença, realizamos um levantamento em 5 Estados com produção comercial intensiva de linhas de corte, abrangendo lotes de aves com diferentes idades. De 2.355 soros testados por ELISA, 89% foram positivos, indicando a alta prevalência do CAV no Brasil, em todos os Estados testados. A análise do soro de aves das 6 até as 70 semanas de idade demonstrou que lotes de 6 a 18 semanas apresentam desuniformidade na imunidade ao CAV, caracterizada por títulos de anticorpos abaixo dos níveis considerados protetores e aves ainda negativas para o CAV. A desuniformidade nos títulos de anticorpos e a ausência dos mesmos são evidentes ainda, mas em menor proporção também até as 24 semanas, enquanto que apenas partir das 25 semanas há 100% de soroconversão, acompanhada de significativa redução da desuniformidade no título de anticorpos das matrizes para menos de 2,5% das aves. Esses resultados fornecem evidência de uma progressiva disseminação do vírus em matrizes de corte, mas com riscos da presença de aves ainda susceptíveis à transmissão vertical e inadequada transferência de imunidade passiva no início do período de postura, que podem culminar em surtos da doença na progênie.

Full Text Available O artigo analisa o discurso da mídia sobre a anemia falciforme. O objetivo é conhecer e analisar o conteúdo das mensagens veiculadas pela mídia impressa sobre a anemia falciforme, doença genética mais prevalente no País. Foram analisadas todas as matérias publicadas sobre o tema da anemia falciforme, entre 1998 e 2002, nos jornais A Tarde (BA, 41 matérias e Folha de S. Paulo (SP, 25 matérias. Para a análise foram selecionadas quatro variáveis: a prevenção, a conscientização do risco, o aconselhamento genético e o recorte racial da doença. A análise das matérias identificou um forte apelo preventivo que acompanha as informações sobre anemia falciforme. O tema da prevenção em genética traz uma série de desafios éticos, em especial dada a impossibilidade legal de interrupção da gestação em casos de diagnóstico de anemia falciforme no feto, o que faz com que haja uma ênfase nos cuidados reprodutivos pré-concepção. No caso da anemia falciforme, a pesquisa mostra ainda que há um apelo no sentido de chamar as pessoas a identificar a doença e buscar atendimento especializado. Mas há também a ênfase na idéia de que as pessoas informadas podem contribuir para prevenir o avanço da doença. Mediar essa tênue fronteira entre prevenção e reconhecimento das liberdades individuais pode ser considerado um desafio não só para a saúde pública, mas também para os meios de comunicação.This article examines the strategies used by the media to approach and disseminate information about the most prevalent genetic disease in Brazil, sickle cell anemia.

Tivemos por objetivo avaliar se doadores de sangue do Hemocentro do Amazonas - Hemoam desenvolvem sideropenia sem anemia após doações consecutivas. A ferritina sérica foi medida em 528 doadores de sangue, do sexo masculino, com idade entre 18 a 61 anos, divididos em 313 doadores de repetição, com 4 ou mais doações regulares, e 215 primodoadores, que compareceram ao Hemocentro do Amazonas no período de setembro de 2001 a junho de 2002. Depleção do depósito de ferro, definida por níveis de ferritina menores de 20 ng/L, foi encontrada em 7,4% [16/215] dos primodoadores e em 48,6% [152/313] dos doadores de repetição. Utilizando-se de um critério mais rigoroso, como valores de ferritina A blood donation of 475 mL could deplete 242 ± 17 mg of iron from blood donors. The objective of this report is to evaluate if blood donors could develop sideropenia without anemia after several donations. Serum levels of ferritin were measured in 528 male blood donors, with ages ranging from 18 to 61 years old. A total of 313 of them had made 4 or more donations and 215 of them were first time donors. They donated blood in the Hemocentro do Amazonas - Hemoam, from September 2001 to June 2002. Deletion of iron stores characterized by serum ferritin levels of less than 20 ng/L was found in 7.4% (16/215 of first time donors, and in 48.6% (152/313 of multiple donors. With more stringent criteria of ferritin values less than 12 ng/L, 3.7% (8/215 of first-time donors as opposed to 24.9% (78/313 of multiple donors showed severe depletions. We concluded that multiple donors, after more than 5 repeated donations, are at risk of depleted iron and ferritin levels. It is important to implant protocols of iron supplementation for these donors to avoid damage to their health and

Essas internações foram avaliadas com relação à presença de CHE inicial ou evolutivo: anemia hemolítica auto-imune ou púrpura trombocitopênica. Todos os pacientes realizaram dois ou mais hemogramas. O diagnóstico de anemia hemolítica auto-imune (AHAI foi estabelecido pela queda acentuada dos níveis de hemoglobina (acima de 2 g/dl, reticulocitose, aumento de desidrogenase láctica (DHL, aumento de bilirrubina indireta e teste de Coombs positivo. As manifestações hematológicas associadas à infecção, neoplasia e anemia aplásica foram excluídas. RESULTADOS: o CHE ocorreu em 14 pacientes (18,9%, com 15 internações. Destes, 11 eram do sexo feminino, sete apresentaram púrpura trombocitopênica, cinco, anemia hemolítica auto-imune e dois, síndrome de Evans. O CHE, como manifestação inicial e isolada do LESJ, foi evidenciado em três pacientes. Todos os pacientes com púrpura trombocitopênica apresentaram sangramento cutâneo (petéquias e/ou equimoses. Todos estavam em atividade da doença e apresentavam simultaneamente outras manifestações do LESJ, particularmente nefrite e vasculite.

Estos conceptos de anemia son instructivos para las enfermeras que trabajan con pacientes en Nicaragua y será de mucha utilidad para desarrollar intervenciones de enfermería para aliviar este problema de salud pública.A anemia e um problema de saúde comum entre as mulheres de todo a mundo inteiro, mas tem havido um mínimo de investigação sobre os conceitos de anemia entre as mulheres. O objetivo deste estudo foi o de analisar os conceitos de anemia em mulheres nicaragüenses com baixos rendimentos. Foi utilizado um desenho qualitativo. Para a coleta de dados, entrevistas semi-estruturadas foram conduzidas, áudio gravadas em espanhol para 14 mulheres. As fitas foram transcritas e tornou-se uma análise conteúdo. Os resultados indicam que poucas mulheres possuem conhecimento biomédico preciso sobre anemia, tal como ingestão de alimentos pobre em ferro. Outras mantiveram outras crenças populares incluindo remédios caseiros, ingestão de leite de égua ou suco de beterraba e certos alimentos como sopa de feijão. A maioria das mulheres não conhecia nenhum sintoma de anemia e poucas relataram que pode progredir para leucemia. Estes conceitos de anemia são esclarecedores para os enfermeiros que trabalham com doentes na Nicarágua e que será muito útil para desenvolver intervenções de enfermagem para minorar o problema de saúde pública.

Full Text Available O caráter crônico da anemia, nos pacientes portadores de anemia falciforme, associado à maior capacidade de liberação de oxigênio pela Hb S, faz com que sejam pouco sintomáticos em relação à anemia e não necessitem de forma rotineira de transfusão de hemácias. Contudo, na vigência de complicações agudas, a queda adicional da hemoglobina pode precipitar descompensação da função cardio-respiratória e colocar em risco a vida do paciente, tornando a transfusão de sangue um recurso terapêutico de grande importância. Em virtude da elevada freqüência de transfusões a que esses pacientes são submetidos, é de fundamental importância o conhecimento dos principais riscos e o diagnóstico adequado das complicações decorrentes da terapia transfusional. Uma forma atípica de reação transfusional, denominada reação transfusional hiperhemolítica, foi descrita recentemente em pacientes com anemia falciforme após transfusão de hemácias aparentemente compatíveis. (4,5,6,7 Nesta condição, transfusões ulteriores podem exacerbar o quadro hemolítico e colocar em risco a vida do paciente. Os mecanismos patofisiológicos exatos dessa entidade ainda não são bem conhecidos e o tratamento consiste na suspensão da transfusão, corticoterapia e/ou administração de imunoglobulina. O objetivo deste trabalho é apresentar o relato de dois casos de reação transfusional hiperhemolítica em pacientes portadores de anemia falciforme.The chronic character of sickle cell anemia associated with the greater capacity to liberate oxygen by the Hb S, results in patients exhibiting few symptoms in relation to the anemia and they do not require regular hemacias transfusions. Nevertheless, in the face of acute complications, the additional drop in hemoglobin can precipitate an imbalance in the cardio-respiratory function and put the life of the patient at risk, making blood transfusion therapy of utmost importance.

A avaliação do estado nutricional é uma das maneiras de indentificar as carências nutricionais, seja, de macronutrientes como a desnutrição protéicocalórica, ou de micronutrientes, como a anemia ferropriva, e que reconhecidamente são problemas de saúde pública mundial. No Brasil, diversos estudos tem demonstrado a extensão e gravidade destes problemas, recomendando medidas urgentes para a sua prevenção e controle. Programas de distribuição de alimentos, de aleitamento materno, de distribuição de leite, de alimentação nas creches, têm sido implantados procurando oferecer uma nutrição adequada à todas as crianças. O objetivo do presente trabalho foi caracterizar pela antropometria e eritrograma sangüíneo, o estado nutricional de crianças em idade pré-escolar atendidas em uma creche municipal da cidade de Matão, no estado de São Paulo. Foram examinadas 47 crianças da instituição e obtidos dados de peso e altura, para avaliar o seu desenvolvimento físico. O sangue foi colhido para o estudo do eritrograma, incluindo resultados sobre a amplitude de distribuição de hemácias e a contagem de reticulócitos. Os valores de peso e altura das crianças foram classificados pelo escore Z, apresentando 3 crianças com valores antropométricos ≤ -2 escore Z, portanto, quadro de desnutrição protéico-calórica e 3 apresentaram valores compatíveis com obesidade (Z ≥ +2.

MÉTODOS: Estudo prospectivo de 108 crianças (idade entre 3 meses e 4,5 anos, 45% masculino seguidas por 15 meses no Hemocentro de Belo Horizonte. Avaliou-se a adesão por meio de três entrevistas com cuidadores, análise de prontuário médico e atividade antibacteriana em uma amostra de urina em 81 crianças. Os antibióticos foram dispensados gratuitamente. RESULTADOS: Penicilina foi usada em 106 casos (maioria via oral, e eritromicina, dois casos. O antibiótico foi detectado na urina de 56% das crianças; 48% dos cuidadores afirmaram nas entrevistas que nenhuma dose deixou de ser administrada; em 89% dos prontuários médicos, não se registrou falha de adesão. Considerando-se aderente a criança que não apresentasse falhas em nenhum ou em apenas um dos métodos, a taxa de adesão foi de 67%. O grau de concordância entre os três métodos para medir a adesão foi baixo. Não se demonstrou qualquer associação entre a taxa de adesão e o gênero, estado nutricional, renda familiar per capita, nível educacional dos cuidadores ou número de membros da família. CONCLUSÕES: A taxa de adesão à antibioticoterapia profilática foi baixa quando avaliada por meio de questionários e testes urinários, e superestimada quando avaliada pela consulta ao prontuário médico. A adesão deve ser preferencialmente avaliada por vários métodos, pois sua mensuração é complexa.

Full Text Available A anemia falciforme é uma doença genética caracterizada pelo alto índice de morbimortalidade, considerada como a mais grave entre as doenças falciformes. As opções terapêuticas mais eficazes atualmente disponíveis para tratamento desta hemoglobinopatia são transplante de medula óssea (TMO e hidroxiuréia (HU. O TMO apesar de ser a medida curativa é considerado de alto risco por apresentar diversos graus de complicações e significativo nível de mortalidade. O uso de HU em crianças portadoras de anemia falciforme tem proporcionado redução de complicações clínicas e aumento significativo na expectativa de vida, por promover elevação dos níveis de hemoglobina fetal, da concentração de hemoglobina e do VCM, bem como redução da hemólise e de eventos vaso-oclusivos. Desse modo, a HU é considerada como melhor opção terapêutica atualmente disponível. Porém, por ser apontada como droga potencialmente carcinogênica, há questionamentos quanto aos benefícios e toxicidades quando utilizada por longo período. Este trabalho teve como proposta, avaliar por meio da revisão literária, os riscos, benefícios e efeitos adversos da hidroxiuréia em crianças.Sickle cell anemia is a genetic disease characterized by a high morbimortality rate, it is considered as the most serious among all sickle cell diseases. The most effective therapeutic options available nowadays for the treatment of this hemoglobinopathy are bone morrow transplantation (BMT and hydroxyurea (HU. BMT is considered a high risk procedure due to the different complications and significant mortality rates. The use of HU for children with sickle cell anemia has reduced the clinical complications and given a significant increase in life expectancy by augmenting the fetal hemoglobin levels and hemoglobin concentrations and reducing cytomegalovirus, as well as reducing hemolysis and vaso-occlusive events. Thus, HU is considered the best therapeutic option currently

Full Text Available A síndrome aguda do tórax (SAT acomete portadores de anemia falciforme e é responsável por cerca de 25% dos óbitos. Relata-se o caso de um homem pardo de 45 anos, alcoolista crônico, sem nenhum antecedente de falcização, com quadro de pneumonia-símile havia sete dias. A radiografia simples do tórax mostrou infiltrado heterogêneo bilateral, com áreas de consolidação e broncograma aéreo e derrame pleural à esquerda. Outros exames laboratoriais revelaram anemia, leucocitose com desvio à esquerda e hipoxemia. Tratado com cefoxitina e amicacina, o paciente evoluiu rapidamente para insuficiência respiratória aguda e morreu 14 horas após a internação. Na necropsia, no exame dos pulmões observaram-se intensa congestão, hemorragia intra-alveolar, dano alveolar difuso e hemácias com morfologia falciforme. O caráter rápido, progressivo e freqüentemente mimetizado por outras doenças torna a SAT um evento dramático e de diagnóstico precoce difícil, sendo, entretanto, obrigatória tê-la sempre em mente, especialmente em um país com grande população da raça negra como o Brasil.

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.

Full Text Available 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 Introdução: As hemoglobinopatias são distúrbios genéticos que se apresentam por padrão de herança recessiva e incluem a anemia falciforme e as síndromes falcêmicas (hemoglobinopatia SC e a S/β-talassemia. Na anemia falciforme as moléculas de adesão dos eritrócritos, leucócitos e plaquetas estão envolvidas na oclusão vascular. Nas síndromes falcêmicas, o quadro costuma ser mais brando. Pesquisas demonstram que o tratamento com hidroxiuréia (HU promove melhora da qualidade de vida dos pacientes que a utilizam. O mesmo tem se mostrado efetivo por aumentar a expressão de hemoglobina fetal (HbF, diminuindo assim as complicações de vaso-oclusão, hemólise e diminuição da expressão de moléculas de adesão. Objetivos: Nesta pesquisa, utilizamos o teste de eletroforese alcalina (pH 8,6 para o monitoramento de expressão da HbF nos pacientes do Ambulatório de Hematologia e Hemoterapia do CHS portadores de anemia falciforme e nos portadores de síndromes falcêmicas em tratamento com HU. Metodologia: Aplicou-se o teste de eletroforese em acetato de celulose em pH alcalino (8,6 e, posteriormente, as fitas de acetato submetidas ao campo elétrico foram coradas por Ponceau, transparentizadas e fixadas em lâminas de microscopia para análise e registro. Resultados: Foram realizados 100 testes cegos em amostras de sangue provenientes dos pacientes do Ambulatório de Anemia Falciforme do CHS, entre os quais analisamos 28 pacientes com anemia falciforme e 12 com síndromes falcêmicas. Na avaliação eletroforética do uso ou não uso de hidroxiuréia nos grupos investigados, observamos que não houve diferença significativa na expressão de HbF (p=0,3173. Além disso, comparamos os índices hematimétricos dos dois grupos e verificamos que os valores médios de VCM e HCM aumentaram em relação à concentração de HU utilizada, embora não tenham sido analisados estatisticamente.

Full Text Available Objetivou-se testar a terapêutica com doses profiláticas de sulfato ferroso no combate à anemia carencial ferropriva, em 620 crianças de 4 a 36 meses de idade, atendidas em duas unidades de saúde do Município de São Paulo, Brasil. As crianças foram submetidas a coleta de sangue para dosagem de hemoglobina. Em seguida, foi prescrito dosagem de 12 mg/dia de ferro elementar, por 30 dias. Observou-se que 25% dos menores de 6 meses apresentaram níveis de hemoglobina inferiores a 11,0 g/dl. As maiores ocorrências de anemia foram detectadas entre os 9 e 23 meses de idade (50,0%. Decorrido o prazo, apenas 37,4% das crianças com anemia e 52,4% das não anêmicas retornaram para reavaliação. Das 299 que foram reavaliadas, somente 157 (52,5% receberam a medicação corretamente. A freqüência de hemoglobinas inferiores a 9,5 g/dl caiu de 17,1% no início, para 8,1% ao final da intervenção. Por outro lado, o percentual de crianças com hemoglobinas superiores a 12,0 g/dl subiu de 13,4%, para 33,4%. As que receberam a suplementação férrica de forma correta registraram queda nos índices de anemia sensivelmente maior que a observada naquelas suplementadas de forma incorreta. Concluiu-se que a terapêutica com doses profiláticas de sulfato ferroso, apesar de se mostrar eficiente na recuperação dos níveis de hemoglobina, apresenta sérios entraves do ponto de vista operacional.The efficacy of medical prophylaxis in the fight against iron deficiency anemia in 620 children aged from four to thirty-six months, attended in two health units of the municipality of S. Paulo, Brazil, was tested. First, the children's blood was tested for hemoglobin level and eletrophoresis. Then they received daily doses of iron sulphate in the form of drops, corresponding to 12 mg/ day of elementary iron, over a 30-day period. Afterwaeds, they were asked to return for re-evaluation. Twenty-five percent of children under 6 months presented hemoglobin levels under

Full Text Available CONTEXT Homozygous (SS sickle-cell anemia complicated by acute splenic sequestration in adults is a rare event, and it has never been reported during pregnancy. CASE REPORT A 25-year-old woman with homozygous (SS sickle-cell disease was hospitalized at 32 weeks' of gestation presenting weakness, abdominal pain, fever and hemoglobin of 2.4 g/dl. Abnormal fetal heart rate was detected by means of cardiotocography, and 5 units of packed red cells were transfused. Cesarean was performed at 37 weeks. Both mother and baby were discharged in a good general condition. CONCLUSION This case report demonstrates the importance of immediate blood transfusion for treatment of fetal distress in cases of splenic sequestration during pregnancy. This treatment is essential for avoiding maternal and fetal complications. CONTEXTO Anemia falciforme homozigótica (SS complicada por sequestro esplênico agudo em adultos é evento raro, e nunca foi relatado durante a gravidez. RELATO DO CASO Uma mulher de 25 anos, portadora de doença falciforme homozigótica (SS, com 32 semanas de gestação, foi internada apresentando fraqueza, dor abdominal, febre e hemoglobina de 2,4 g/dl. Frequência cardíaca fetal anormal foi detectada pela cardiotocografia e a paciente recebeu 5 unidades de concentrado de hemácias. Cesariana foi realizada com 37 semanas. Mãe e filho receberam alta em bom estado geral. CONCLUSÃO Este relato de caso demonstra a importância da transfusão imediata para o tratamento de sofrimento fetal nos casos de sequestro esplênico durante a gestação. Este tratamento é imprescindível para se evitarem complicações maternas e fetais.

MÉTODOS: Estudo transversal com 102 pacientes SS e 100 doadores de sangue. Realizou-se a fenotipagem eritrocitária, teste de Coombs Direto e Indireto e detecção de anticorpos irregulares por painel de hemácias fenotipadas. Os dados foram comparados por meio do teste de Mann-Whitney, qui-quadrado ou teste exato de Fisher. Para análise dos fatores associados à aloimunização utilizou-se a regressão logística univariada e múltipla. RESULTADOS: Os antígenos mais frequentes entre os pacientes e os doadores foram c, e, M, s, JK(a. Observaram-se diferenças significativas entre as frequências dos fenótipos dos pacientes e dos doadores em relação aos antígenos s, FY(a e JK(b. Dos 79 pacientes transfundidos, 10 (12,7% apresentaram Coombs Indireto positivo. Detectaram-se 13 aloanticorpos, sete do sistema Rh, dois do Kell e quatro não identificados. Os fatores associados à aloimunização foram o intervalo de tempo entre a última transfusão e a data do teste e ter recebido mais de dez transfusões de hemácias. Receber mais de dez transfusões representou uma chance 16,39 (IC 95%: 2,23-120,59 vezes maior de ser aloimunizado, em comparação aos que receberam menos que dez. CONCLUSÃO: A prevalência de aloimunização nos pacientes SS foi 12,7%, sendo 70% dos anticorpos encontrados pertencentes a grupos sanguíneos Rh e Kell. Este estudo mostra a importância da fenotipagem eritrocitária em doadores e receptores para diminuir o risco de aloimunização.OBJECTIVE: To determine erythrocyte phenotyping in blood donors and patients with sickle cell anemia (SS treated at Hemocentro of Alagoas and describe the frequency and factors associated with erythrocyte alloimmunization.

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

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

Methods: Retrospective analysis of 26 pediatric patients with aplastic anemia, treated between 1996 and 2011 with rabbit antithymocyte globulin plus cyclosporine. Results: The overall response rate at six months was 34.6% (9/26, and the cumulative incidence of relapse was 26.5% (95% confidence interval [CI]: 1.4%-66% at 5 years. The cumulative incidence of clonal evolution after immunosuppressive therapy was 8.3% (95% CI: 0.001%-53.7% at five years with both clonal evolutions in non -responders who acquired monosomy 7 karyotype. The overall survival at five years was 73.6% (95% CI: 49.2%-87.5%. Conclusions: The present results confirm the poor response rate with rabbit antithymocyte globulin as first therapy in pediatrics patients, similar to what has been reported for patients of all ages. This confirmation is problematic in Brazil, given the lack of horse antithymocyte globulin in many markets outside the United States.

Full Text Available FUNDAMENTO: Anemia está associada à pior evolução nos pacientes com insuficiência cardíaca (IC. Entretanto, há poucos estudos sobre a anemia nos pacientes com IC avançada. OBJETIVO: Avaliar as características da anemia na IC em fase avançada. MÉTODOS: Foram incluídos 99 pacientes hospitalizados para compensação de IC (CF IV/NYHA, com idade > 18 anos e FEVE 12 g/dl. A anemia foi marcador independente de mau prognóstico na análise multivariada (mortalidade 47% vs 24,6%, p = 0,016, risco relativo 2,54. CONCLUSÃO: Anemia acomete, aproximadamente, 1/3 dos pacientes com IC avançada, e a deficiência de ferro é uma importante etiologia. Pacientes anêmicos são mais idosos e apresentaram função renal mais deteriorada. A melhora da congestão não foi suficiente para melhorar a anemia na maioria dos casos. Nos pacientes com IC avançada, a anemia é marcador independente de mau prognóstico.

OBJETIVO: Avaliar se GOS e PDX estimulam a absorção de ferro em ratos gastrectomizados e normais. MÉTODOS: Os ratos foram laparotomizadas (controle falso-operado e parcialmente gastrectomizados (Billroth II em grupos de 20 animais. Os animais de ambos os tratamentos foram posteriormente submetidos à dieta controle (AIN-93M ou a mesma dieta suplementada com GOS e PDX (25 g/kg de dieta cada durante oito semanas e divididos em quatro subgrupos: sham-operados e gastrectomizados sem GOS e PDX, sham-operados e gastrectomizados com GOS e PDX. Dois animais morreram durante o experimento. Todos os ratos gastrectomizados receberam uma injeção intramuscular de vitamina B-12 a cada duas semanas. Hematócrito (HCT e concentração de hemoglobina (HGB foram dosados no início e nos dias 30 e 56 dias após o início da alimentação. No último dia do estudo, o sangue total foi coletado para determinação da concentração de ferro sérico. RESULTADOS: Na dieta com GOS e PDX a excreção de ferro nas fezes foi significativamente menor do que no grupo sem prebióticos. Absorção aparente de ferro e ferro sérico foram maiores nos grupos alimentados com GOS e PDX (ambos grupos: sham operados e gastrectomizados do que nos grupos não alimentados com GOS e PDX. O HCT e HGB foram significativamente menores nos ratos gastrectomizados que no grupo controle, entretanto, a suplementação com GOS e PDX melhorou os níveis de HGB neste grupo. CONCLUSÃO: A associação de GOS e PDX aumenta a absorção de ferro em ratos shamoperados e gastrectomizados e ainda previne a anemia pós-gastrectomia.BACKGROUND: The ingestion of two prebiotics, galactooligosaccharide (GOS and polydextrose (PDX, leads to an increase in iron absorption and promotes

MÉTODOS: Estudou-se amostra domiciliar de menores de cinco anos do Município de São Paulo (n=584 em 1995 e 1996. O diagnóstico de anemia (hemoglobina OBJECTIVE: To evaluate the influence of the consumption of cow's milk on the risk of anemia during childhood in the city of São Paulo. METHODS: We have studied a probabilistic sample (n=584 of underfive children living in the city of São Paulo, southeastern Brazil, between 1995 and 1996. Anemia (hemoglobin <11g/dl was diagnosed using capillary blood obtained by fingertip puncture. The cow's milk content and the density of heme and nonheme iron in the child's diet were obtained using 24-hour recall questionnaires. Multiple linear and logistic regression models were used to study the association between cow's milk content in the diet and hemoglobin concentration or risk of anemia, and included statistical control for potential confounders (age, sex, birthweight, presence of intestinal parasites, family income, and mother's schooling. RESULTS: The prevalence of anemia was 45.2% and the mean contribution of milk to the total caloric content of the children's diets was 22.0%. The association between milk consumption and risk of anemia remained significant, even after considering the dilutive effect of milk consumption on the density of iron in the diet, thus indicating a possible inhibitor effect of milk on the absorption of the iron present in the other foods ingested by the child. CONCLUSIONS: The relative participation of cow's milk in the child's diet showed a significant positive association with risk of anemia in children between ages six and 60 months, regardless of the density of iron in the diet.

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

Directory of Open Access Journals (Sweden)

Andrea dos Reis Lemos

2010-01-01

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

Full Text Available O conhecimento do potencial de biodisponibilidade de ferro da dieta de uma população é imprescindível na implantação de um programa de fortificação com esse mineral. A quantificação da capacidade de absorção do ferro dietético foi efetuada em três refeições, habituais entre os paulistas: desjejum (pão, margarina, café com açúcar, almoço (arroz, feijão, carne e café com açúcar e jantar (arroz, feijão, ovo frito, café com açúcar, servidas a 28 indivíduos adultos, de ambos os sexos, aparentemente sadios. As densidades do ferro biodisponível (dFeB nas refeições estudadas foram: desjejum dFeB = 0,23; almoço dFeB = 0,73 e jantar dFeB = 0,28. Os valores encontrados, bastante inferiores aos adequados para suprir o requerimento de ferro da mulher, sugerem que a fortificação não é estratégia efetiva no controle da anemia ferropriva, quando aplicada às refeições de composição igual àquelas estudadas.A knowledge of the bioavailability of dietary iron is indispensable to the promotion of an iron fortification program. The quantification of that property was determined for three common meals, breakfast (bread, margarine, coffee with sugar, lunch (rice, beans, meat, coffee with sugar and dinner (rice, beans, fried egg, coffee with sugar served to 28 apparently healthy adults of both sexes. The bioavailable iron density (dFe B found was: breakfast - dFe B = 0,23; lunch - dFe B = 0,73 and dinner - dFe B = 0,28. These results, insufficient to supply the iron required by women, suggest that fortification is not an effective strategy for control of iron deficiency anemia if applied to meals like those studied.

2003-01-01

Full Text Available No presente artigo abordaram-se vários aspectos relacionados à natureza molecular da anemia falciforme, desordem hematológica de caráter hereditário que acomete expressivo número de indivíduos em várias regiões do mundo. As pesquisas realizadas em torno desta patologia da hemácia, ao longo de quase um século, a partir de 1910, cooperaram para a criação de um novo e importante segmento da ciência, denominado biologia molecular. A descoberta dos polimorfismos da mutação (GAT->GTG no gene que codifica a cadeia beta da hemoglobina, originando diferentes haplótipos da doença, permitiu um melhor e mais amplo conhecimento em torno da heterogeneidade clínica nos pacientes falcêmicos. Analisando a hemoglobina na sua estrutura normal e mutante, sua produção e evolução, pode-se ter um entendimento mais completo da fisiopatologia desta doença e da sua complexidade clínica.

Full Text Available Embora as transfusões de concentrado de hemácias sejam importantes para o tratamento de pacientes com anemia falciforme, elas acarretam riscos imunológicos tais como a aloimunização a antígenos eritrocitários. Aproximadamente 50% dos pacientes de anemia falciforme recebem transfusões no decorrer da vida, e entre 5 e 10% desses pacientes são submetidos a um programa de transfusão crônica. A aloimunização eritrocitária é uma complicação relativamente comum, podendo até mesmo levar a reações transfusionais hemolíticas tardias, contribuindo para aumentar as comorbidades da doença. Importantes medidas para prevenção dessas complicações nesses pacientes são o uso de hemácias previamente fenotipadas, além da fenotipagem do próprio receptor de concentrado de hemácias, determinando seu correto perfil fenotípico e possibilitando a escolha de concentrado de hemácias com antígenos correspondentes ao do paciente a ser transfundido. Extensa genotipagem eritrocitária profilática para selecionar doadores para pacientes que receberão repetidas transfusões durante um longo período é uma aplicação atraente de tipagem de sangue baseado em DNA. Isso é particularmente relevante para pacientes com doença falciforme, nos quais a taxa de aloimunização é elevada.

As regiões sócio-ecológicas da Bacia do Alto Juruá, Alto Acre e Alta Bacia do Purus apresentaram os maiores índices da doença, o que caracteriza a associação entre região e positividade. Essas áreas são fronteiriças com o Peru, Bolívia e o Estado do Amazonas, são distantes de Rio Branco, capital do Estado, onde muitas vezes é difícil o acesso pelas estradas, revelando serem áreas de risco. As regiões Oriental e Rio Branco apresentaram baixos índices de positividade. Não se observou diferença estatística entre animais positivos e negativos quanto à espécie, sexo, raça e idade.

Inborn anemias in mice

International Nuclear Information System (INIS)

Bernstein, S.E.; Barker, J.E.; Russell, E.S.

1981-06-01

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

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

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

Full Text Available This study focused on clinical, hematological, and molecular aspects of sickle cell anemia pediatric patients from two different cites in Brazil. Seventy-one patients from São Paulo and Salvador, aged 3 to 18 years, were evaluated. Hematological analyses, betaS globin gene haplotypes, and alpha2 3.7kb-thalassemia were performed. Numbers of hospitalizations due to vaso-occlusive crises, infections, stroke, and cholelithiasis were investigated. São Paulo had more hospitalizations from vaso-occlusion, cholelithiasis, and stroke than Salvador. The Ben/CAR genotype predominated in both cities. alpha2 3.7kb-thalassemia had a frequency of 28.2% in Salvador, mostly with Ben/CAR genotype (45.0%, while São Paulo had 22.5% with similar frequencies of the Ben/ CAR and CAR/CAR genotypes. Sickle cell anemia patients from São Paulo also had more episodes of stroke, which was observed among CAR/CAR, atypical, and BEN/CAR haplotypes. In Salvador stroke was only observed in the Ben/CAR genotype. Cholelithiasis had similar frequencies in the two cities. These data suggest a milder phenotype among patients in Salvador, possibly due to genetic, environmental, and socioeconomic factors. Further studies are needed to elucidate modulating factors and phenotype association.O objetivo desse estudo foi avaliar aspectos clínicos, hematológicos e moleculares de pacientes pediátricos portadores de anemia falciforme em duas cidades brasileiras: Salvador e São Paulo. Foram estudados 71 pacientes com idades variando entre 3 a 18 anos, analisando-se os seguintes aspectos: perfis hematológicos, haplótipos dos genes da globina beta, presença de talassemia alfa-2(3.7kb, número de internações por vaso-oclusão, infecção, presença de acidente vascular cerebral e litíase biliar.

Full Text Available A anemia por deficiência de ferro em crianças é um dos maiores problemas nutricionais enfrentados pelos países em desenvolvimento. Estudos controlados indicam que doses intermitentes de sais de ferro podem ter eficácia semelhante à obtida com o esquema tradicional diário. O objetivo desse estudo é avaliar, em uma população onde a anemia na infância é endêmica, a efetividade da prescrição preventiva de doses semanais de sulfato ferroso a todas as crianças entre seis e 59 meses de idade por um período de seis meses. Crianças dos grupos controle e intervenção foram selecionadas a partir de uma amostra aleatória da população de crianças da cidade de São Paulo. Os pais das crianças do grupo intervenção receberam orientação nutricional e frascos de solução de sulfato ferroso com a instrução de ofertá-la aos filhos uma vez por semana até a próxima visita da equipe de pesquisa, que ocorreria em aproximadamente seis meses. Os pais das crianças do grupo controle receberam somente orientação nutricional. O efeito da intervenção foi avaliado por mudanças na concentração da hemoglobina e na prevalência de anemia. As comparações entre os dois grupos foram baseadas na "intenção-de-tratar" e todas as estimativas foram ajustadas para concentração inicial de hemoglobina, idade inicial, duração do seguimento e renda familiar. O ganho médio de hemoglobina devido à intervenção foi de 4,0 g/l e a queda na prevalência de anemia foi de mais de 50%. A intervenção foi particularmente eficiente em prevenir o declínio da concentração de hemoglobina durante os dois primeiros anos de vida. Esse estudo demonstra que, em condições similares àquelas que poderiam facilmente ser reproduzidas por programas regulares de saúde pública, a prescrição universal de doses semanais de sulfato ferroso reduz significativamente o risco de anemia na infância.Iron-deficiency anemia in children remains one of the most

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.

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

The Prevalence of Anemia and Moderate-Severe Anemia in the US Population (NHANES 2003-2012)

Science.gov (United States)

2016-01-01

Since anemia is associated with poor health outcomes, the prevalence of anemia is a significant public health indicator. Even though anemia is primarily caused by iron deficiency, low oxygen-carrying capacity may result from other conditions such as chronic diseases, which remain a relevant health concern in the United States. However, studies examining current rates of anemia in the total US population and in more specific subgroups are limited. Data from five National Health and Nutrition Examination Surveys (NHANES) from 2003 to 2012 were analyzed to assess two outcomes: anemia and moderate-severe anemia, which were based upon serum hemoglobin levels (Hb) as per World Health Organization (WHO) definitions. Statistical analysis using SAS examined temporal trends and the prevalence of anemia among sexes, age groups, and races/ethnicities. The study estimated that an average of 5.6% of the U.S. population met the criteria for anemia and 1.5% for moderate-severe anemia during this 10-year period. High-risk groups such as pregnant women, elderly persons, women of reproductive age, non-Hispanic blacks, and Hispanics were identified, and relationships between multiple risk factors were examined. Rates of anemia in men increased monotonically with age, while that of women increased bimodally with peaks in age group 40–49 years and 80–85 years. The effect of risk factors was observed to compound. For instance, the prevalence of anemia in black women aged 80–85 years was 35.6%, 6.4 times higher than the population average. Moreover, anemia is a growing problem because of the increased prevalence of anemia (4.0% to 7.1%) and moderate-severe anemia (1.0% to 1.9%), which nearly doubled from 2003–2004 to 2011–2012. Thus, these results augment the current knowledge on anemia prevalence, severity, and distribution among subgroups in the US and raised anemia as an issue that requires urgent public health intervention.

O ferro é um elemento essencial a todos os organismos vivos e alterações em sua homeostase resultam em quadro de deficiência ou acúmulo, ambos com alta prevalência e relevância clínica. A última década foi marcada pela geração de conhecimentos importantes, que estão contribuindo para a elucidação dos mecanismos moleculares da homeostase do ferro. Foram identificadas proteínas, envolvidas na absorção intestinal do ferro não-heme, e progressos significativos foram feitos no entendimento da regulação da absorção intestinal do ferro, sendo identificadas várias moléculas candidatas. As bases moleculares da homeostase do ferro ainda não foram totalmente elucidadas, porém as informações já existentes sugerem que, em condições fisiológicas, a absorção, o transporte e o armazenamento sejam feitos por moléculas altamente especializadas e, em especial, a absorção, com mecanismos saturáveis em baixa concentração. No entanto, a absorção pode ocorrer por vias menos sujeitas ao controle, dependendo da sobrecarga e da natureza química do composto utilizado. Estas informações advogam a favor de uma revisão nas estratégias de combate à anemia ferropriva. PALAVRAS-CHAVE: Absorção do ferro; DMT-1; hepahestina; ceruloplasmina; ferroportina; hepcidina.

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

Tapper (1999 argumenta que uma das conseqüências dessa política foi a criação de uma comunidade negra cidadã e responsável. O Programa de Anemia Falciforme, desenvolvido pelo governo brasileiro com participação de ativistas negros a partir da década de 1990, também contribui para a formação e de uma "comunidade negra responsável". O argumento do artigo é que a anemia falciforme torna-se muito mais que uma doença a ser erradicada. O discurso em torno dela é um poderoso elemento no processo de naturalização da "raça negra" (e, por oposição lógica e política, da "raça branca" num país que se imaginava como biológica e culturalmente híbrido.This essay reflects on the social significance of growing interest in sickle cell anemia and other illnesses associated with the black body in Brazil.

Full Text Available Estima-se que dois bilhões de indivíduos sejam anêmicos e que a deficiência de ferro ocorra em cerca de quatro bilhões de indivíduos, afetando a população de países desenvolvidos e, com mais intensidade, a dos países em desenvolvimento. No Brasil, estudos apontam elevada prevalência de anemia ferropriva em crianças dependendo da região e da faixa etária. A velocidade de crescimento aumentada, determinando maior necessidade de ferro, aliada a dieta inadequada em ferro e ao desmame precoce, contribuem para a elevada prevalência de anemia, principalmente nos dois primeiros anos de vida. Outros fatores de risco são apontados, como a prematuridade, o baixo peso ao nascer, a ligadura precoce do cordão umbilical e o abandono do aleitamento materno exclusivo. O impacto da deficiência de ferro no crescimento permanece controverso, uma vez que inúmeras outras variáveis poderiam contribuir para melhora ou piora do estado nutricional. Alterações no desenvolvimento psicomotor e neurocognitivo, nos lactentes deficientes com ferro, têm sido relatadas em diversos estudos, sendo controversa a recuperação após o tratamento. Há trabalhos que demonstram queda no rendimento intelectual e nas aquisições cognitivas também no período escolar e adolescência, com reversão após a terapia marcial. Entre as medidas preventivas, a educação nutricional é a forma ideal; entretanto, frente à elevada prevalência, outras formas de prevenção devem ser também utilizadas, como a suplementação com ferro e a fortificação de alimentos com ferro.Iron deficiency anemia afflicts an estimated two billion people and iron deficiency approximately 4 billion people in developed countries and is even more common in developing countries.

As amostras sanguíneas foram analisadas no Lanagro/MG por meio da técnica de imunodifusão em ágar gel (IDGA. No momento da coleta de sangue, também foi aplicado um questionário epidemiológico para a análise de possíveis fatores de risco. A prevalência de AIE nas UPA foi estimada em 2,29%, (IC 95%: 1,01-4,2% e nos animais foi de 1,81% (IC 95%: 0,55-3,07%. A prevalência foi significativamente maior em muares do que em equinos. Não foi possível comprovar a presença de nenhum outro fator de risco associado à doença. Este estudo demonstra que a prevalência da AIE em equídeos de tração é baixa no Distrito Federal, porém mais alta do que os dados de vigilância de rotina sugerem, o que justifica a eutanásia dos equídeos reagentes, com a finalidade de promover a erradicação da enfermidade. Ratifica-se a importância da realização de exames periódicos nesses animais e a manutenção das atividades de vigilância.

Full Text Available As propostas de políticas de saúde para a população negra têm uma história recente no cenário político brasileiro, com um destaque especial para o Programa Nacional de Anemia Falciforme (PAF. Esse programa é o resultado das ações políticas do movimento negro em prol do reconhecimento da anemia falciforme como uma doença prevalente na população negra brasileira. No seio dessa ação política foram elaborados discursos sobre a anemia falciforme que ressaltam, a partir de pressupostos biológicos e epidemiológicos, o caráter racial dessa doença. O propósito deste artigo é criticar tais pressupostos, enfatizando as implicações éticas decorrentes da racialização das doenças.The political propositions in health for the black population have a recent history in the Brazilian political setting, with a special highlight to the National Program on Sickle Cell Anemia. This program is an output of political actions launched by the black movement on behalf of the recognition of sickle cell anemia as prevalent disease among Brazilian black population. Discourses on the sickle cell anemia have been built in the core of that political action, stressing, based in biological and epidemiological assumptions, the racial character of this disease. The objective of this article is to criticize those assumptions, emphasizing the ethical implications of disease racialization.

Megaloblastic anemia and sideroblastic anemia is accompanied by diabetes insipidus (DI, diabetes mellitus (DM ,optic atrophy (OA and deafness (D. Neutropenia and thrombocytopenia are also present. We report a 7 month old girl with congenital macrocytic anemia; a rare clinical feature of Wolfram,s syndrome with increased plasma levels of blood glucose, both of which dramatically responded to administration of thiamine in large doses . The patient also had neurosensorial deafness, but no improvement was observed in the deafness. We presented the case because thiamine-responsive megaloblastic anemia is a rare clinical presentation of Wolfram syndrome and after institution of treatment with thiamine, the anemia and hyperglycemia returned to normal.

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.

Anemia of Chronic Disease and Iron Deficiency Anemia in Inflammatory Bowel Diseases: Pathophysiology, Diagnosis, and Treatment.

Science.gov (United States)

Murawska, Natalia; Fabisiak, Adam; Fichna, Jakub

2016-05-01

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

Anemia of Chronic Liver Diseases

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

Anemia ancilostomótica: estudo da fisiopatologia Ancylostomotic anemia: a contribution to the study of its physiopathology

Directory of Open Access Journals (Sweden)

Victório Maspes

1981-12-01

Full Text Available Foram estudados 17 casos de ancilostomose e determinados alguns parâmetros hematológicos como: dosagem de hemoglobina, do ferro sérico e da transferrina, contagem de hemácias, hematócrito, volume corpuscular médio (VCM e hemoglobina corpuscular média (HCM. O estudo incluiu também a obtenção de alguns dados eritrocinéticos, como a determinação da velocidade de decaimento do ferro plasmático (T1V2 do 59Fe e da incorporação do ferro à hemoglobina. O estudo radioisotópico permitiu ainda determinar o volume de sangue e a quantidade de hemoglobina perdida nas fezes, bem como o teor de ferro reabsorvido dessa hemoglobina. Estabeleceram também o grau de infecção através da contagem de ovos e de vermes nas fezes. Os doentes não apresentaram evidente alteração nutricional. A carência de ferro foi o fator comum a todos os casos que exibiram anemia, constituindo a base fisiopatológica da anemia ancilostomótica. O verme fixado à mucosa duodenal suga o sangue do hospedeiro e esta espoliação de sangue a longo prazo provoca a anemia. O volume de sangue perdido é geralmente proporcional ao grau de infecção, mas a quantidade de hemoglobina perdida mostrou ser independente do volume de sangue espoliado. A reabsorção de grande parte do ferro da hemoglobina perdida na luz intestinal concorre para que a anemia se estabeleça mais tardiamente que em outras hemorragias como a vaginal. Os indivíduos anêmicos foram submetidos a transfusões de sangue e com isso apresentaram melhora clínica e laboratorial, imediata mas temporária. A cura clínica foi estabelecida somente após tratamento adequado com vermífugos.Seventeen ancylostomotic patients was studied and several hematological parameters: hemoglobin level, serum iron level and transferrin, erythrocyte count, hematocrit, mean corpuscular volume (VCM and mean corpuscular hemoglobin (HCM was established.

Cancer-related anemia

Abdel-Rzaeq, Hikmat N.

2004-01-01

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

Iron deficiency or anemia of inflammation? : Differential diagnosis and mechanisms of anemia of inflammation.

Science.gov (United States)

Nairz, Manfred; Theurl, Igor; Wolf, Dominik; Weiss, Günter

2016-10-01

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

Full Text Available Foram analisados 47 pacientes com diagnóstico clínico, laboratorial e molecular de anemia falciforme, residentes em Fortaleza, Ceará, com a finalidade de fornecer informações sobre a influência dos haplótipos do gene da βS- globina nas características fenotípicas desta doença. A determinação dos valores hematológicos foi realizada em contador automático de células sanguíneas, e os níveis de HbF foram determinados pela técnica da desnaturação alcalina. O DNA foi isolado de leucócitos, a partir de amostras de sangue total. A análise dos haplótipos da mutação βS foi realizada por PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Lenght Polymorphism, sendo analisados seis sítios polimórficos de restrição. Os pacientes foram divididos em cinco grupos, de acordo com o tipo de haplótipo: Bantu/Bantu, Benin/Benin, Bantu/Benin, Bantu/Atípico e Benin/Atípico. O nível de significância considerado nas análises foi p<0,05. Na comparação entre os haplótipos e as características hematológicas estudadas, apenas os valores de HbF e Ht apresentaram diferença estatisticamente significativa. Os níveis de HbF foram maiores no haplótipo Benin, seguido do haplótipo Bantu, o que está em conformidade com os dados da literatura. Foram demonstrados maior presença de crises vaso-oclusivas e episódios de pneumonia no haplótipo Benin/Atípico do que no haplótipo Bantu/Atípico; e maior presença de crises de infecção urinária no haplótipo Benin/Atípico do que no haplótipo Benin/Benin. Não houve diferença estatisticamente significativa entre os haplótipos Bantu/Bantu e Benin/Benin em relação às complicações clínicas; entretanto, foi observado que o haplótipo Bantu/Bantu tem uma maior frequência em todos os eventos clínicos estudados quando comparado ao Benin/Benin. Os resultados demonstram que o tipo de haplótipo do gene da βS-globina influencia as características fenotípicas dos pacientes com

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

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

The aim was to determine the prevalence of anemia, as well as its association with growth retardation. Data were collected from May to July 2000, and determination of hemoglobin (HGB employed an STKS Coulter counter. Two cut-off points were used to classify anemia, both established by the World Health Organization: HGB < 11.5g/dl and HGB < 12.0g/dl. The indicators height/age (H/A, weight/age (W/A, and weight/height (W/H below -2.0 standard deviations from the NCHS reference were diagnosed as growth retardation. Prevalence of anemia was 9.9% when HGB < 11.5g/dl was used, and 25.4% when the cut-off point was HGB < 12.0g/dl. Growth retardation was detected in 6.2% of children according to H/A, 4.0% for W/A, and 3.0% for W/H. There was no statistically significant association between the variables in the study. These findings confirm results of previous surveys where prevalence of anemia was much higher than that of growth retardation. The severe consequences of anemia in this age group justify the implementation of broad public policies to overcome this nutritional deficiency.

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

Genetic diagnosis for congenital hemolytic anemia.

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

Atualmente a defi ciência de ferro é um dos problemas nutricionais mais prevalentes no mundo, acometendo grande número de crianças e mulheres. Não existem dados que estimem a real prevalência da deficiência de ferro no Brasil, porém, tendo-se a anemia como indicadora indireta, estima-se que, nos países não industrializados, a maioria das crianças em idade pré-escolar e as gestantes, apresentem deficiência de ferro, sendo mais elevada em crianças. Estudos no Brasil mostram que cerca de 40% das crianças possuem prevalência de anemia, já entre as gestantes, este valor varia de acordo com o período de gestação, oscilando entre 12 e 55%. Os resultados desse estudo são significativos e sugerem a necessidade para o desenvolvimento de um produto enriquecido com ferro que seja de fácil preparo e acessível às populações de risco, permitindo-lhes suprir de forma efi ciente, as necessidades diárias individuais de ferro. Desta forma, desenvolveu-se um suco de uva em pó enriquecido com ferro para atender possivelmente esse desafi o. As análises realizadas mostraram ser um produto com elevado valor de ferro (6mg/200ml de suco o que representa 60% das necessidades de uma criança em idade pré-escolar, conforme a IDR.

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

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

The etiology of iron deficiency (ID) without anemia in young men is unclear, and there are no evidence-based recommendations for the required gastrointestinal (GI) evaluation. The aims of this study were to examine the incidence of significant GI pathology and the development of anemia during the follow-up of young men presenting with ID, but without anemia. All young men (18-30 years) who served in the Israel Defense Forces during the years 2005-2013 and had at least a single laboratory test indicative of ID without anemia were followed until the diagnosis of significant GI pathology or discharge from military service. The study population included 2061 young men (mean age 20.7±1.8). During follow-up of 3150 person years, significant GI pathologies were diagnosed in 39 patients: inflammatory bowel disease in 25 (1.2%), celiac disease in 8 (0.4%), and peptic disease in 4 (0.1%). No cases of GI-related cancer were diagnosed. ID anemia developed during follow-up in 203 (9.8%). Lower baseline hemoglobin levels, lower ferritin levels, and younger age at diagnosis were more common among those who developed anemia. The development of anemia was a predisposing factor for the diagnosis of GI pathology (risk ratio=3.60, 95% confidence interval 1.34-8.32, P=0.012). Significant GI pathology is very uncommon in young men presenting with ID. Overt anemia developed in close to 10% of the study cohort. Therefore, we advise simple GI evaluation (celiac serology, C-reactive protein or fecal calprotectin, and urease breath test) as well as follow-up in this population.

2016-09-01

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

Management of Anemia of Inflammation in the Elderly

Antonio Macciò

2012-01-01

Full Text Available Anemia of any degree is recognized as a significant independent contributor to morbidity, mortality, and frailty in elderly patients. Among the broad types of anemia in the elderly a peculiar role seems to be played by the anemia associated with chronic inflammation, which remains the most complex form of anemia to treat. The origin of this nonspecific inflammation in the elderly has not yet been clarified. It seems more plausible that the oxidative stress that accompanies ageing is the real cause of chronic inflammation of the elderly and that the same oxidative stress is actually a major cause of this anemia. The erythropoietic agents have the potential to play a therapeutic role in this patient population. Despite some promising results, rHuEPO does not have a specific indication for the treatment of anemia in the elderly. Moreover, concerns about their side effects have spurred the search for alternatives. Considering the etiopathogenetic mechanisms of anemia of inflammation in the elderly population, an integrated nutritional/dietetic approach with nutraceuticals that can manipulate oxidative stress and related inflammation may prevent the onset of this anemia and its negative impact on patients’ performance and quality of life.

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.

Management of Iron Deficiency Anemia

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

Unexpected Anemia and Reticulocytopenia in an Adolescent With Sickle Cell Anemia Receiving Chronic Transfusion Therapy.

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

Family structure and child anemia in Mexico.

Schmeer, Kammi K

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.

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

MÉTODOS: Recém-nascidos foram randomizados para compor os grupos intervenção e controle. As mães do grupo intervenção receberam orientações dietéticas durante 10 visitas domiciliares realizadas nos primeiros 10 dias após o parto, mensalmente até os 6 meses e, posteriormente, aos 8, 10 e 12 meses; o grupo controle recebeu apenas visitas para coletas de dados nas idades de 6 e 12 meses. Quando as crianças apresentaram idade de 12 a 16 meses, realizou-se inquérito alimentar recordatório de 24 horas, hemograma e ferritina. RESULTADOS: Os resultados mostraram que não houve evidência de efeito da intervenção sobre a ocorrência de anemia, a qual foi de 66,5% no grupo intervenção e de 61,8% no grupo controle. Também não houve diferença na prevalência de deficiência de ferro e anemia por deficiência de ferro entre os grupos. No entanto, foi evidenciado melhor padrão alimentar nas crianças do grupo intervenção. Maior proporção de crianças do grupo intervenção foi amamentada exclusivamente na idade de 4 a 6 meses e amamentada nas idades de 6 a 12 meses. Além de apresentar maior consumo de carne e dietas com maior biodisponibilidade em ferro, também apresentaram menor consumo de leite de vaca e cálcio do que as crianças do grupo controle. CONCLUSÃO: A intervenção não resultou em redução na prevalência de anemia, deficiência de ferro e anemia por deficiência de ferro.

Multidisciplinary approach to anemia

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.

Full Text Available A disponibilidade do ferro é fator importante na dieta, pois a anemia ferropriva atinge grande parte da população mundial. A cisteína e a vitamina C são fatores que melhoram sua absorção. A pesquisa teve por objetivos avaliar a disponibilidade de ferro em carne, feijão comum (Phaseolus vulgaris e a combinação de arroz e tomate ao feijão, bem como analisar se o ácido fítico, o ácido oxálico e os taninos das combinações contendo feijão influenciam na disponibilidade de ferro de forma significativa. Os alimentos foram preparados para consumo e as amostras obtidas com a combinação de carne, feijão, arroz e tomate foram: A1 - carne bovina; A2 - feijão comum; A3 - feijão comum e tomate; A4 - feijão comum e arroz; e A5 - feijão comum, arroz e tomate. Foram realizadas as análises de taninos, ácido fítico, ácido oxálico, vitamina C e teor e diálise de ferro in vitro. Os teores de taninos, ácido fítico e ácido oxálico foram baixos para influenciar a disponibilidade do ferro.

Full Text Available INTRODUCTION: Anemia is defined as haemoglobin level in the blood below the lower extreme of the normal range for the age and sex of the individual. According to WHO, in developing countries the prevalence of anemia among pregnant women averages 60%, ranging between 35 to 100% among different regions of the world. A hemoglobin concentration below 11.0g/dl or packed cell volume (PCV of less than 33.0% is regarded as anemia during pregnancy by the WHO. It occurs in 40 - 80% of the pregnant women. Iron and folic acid defici encies, malaria, intestinal parasitic infections and hemoglobinopathies are the principal causes of anemia in pregnancy. Predisposing factors include young age, grand multiparity, low socioeconomic status, illiteracy, ignorance and short intervals of pregn ancy. AIM AND OBJECTIVES: 1. To study various patterns of anemia in pregnant women having haemoglobin level < 11 gm%. 2. To determine the most common pattern of anemia in pregnancy based on red cell morphology. MATERIALS AND METHODS: This study is a prospe ctive study over a period of one year from September 2014 to August 2015 in the department of pathology, Andhra medical college, Visakhapatnam . The study was conducted on 120 pregnant women whose haemoglobin level is < 11 gm/dl. All the haemotological parameters & peripheral blood smear stained by Leishman’s stain were evaluated. Complete clinical & obstetric history was recorded. Socioeconomic status was also noted. RESULTS: Out of 120 cases of anemia, we found 47 patie nts (39.1% having dimorphic anemia, 36(30% – microcytic hypochromic anemia, 23(19.1% - normocytic hypochromic anemia, 11(9.16% - sickle cell anemia and 1(0.83% case of pancytopenia. Maximum cases were seen in the age group of 21 - 30 years. 52 cases (43. 3% were primigravida and remaining 68 cases (56.6% were gravida two to four. 20 cases (16.6% were diagnosed in the first trimester, 38 cases (31.6% in the second trimester & 62 cases (51.6s% in the

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

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.)

Uma criança apresentou acidente vascular cerebral com paresia de hemicorpo esquerdo, e a outra, ataque isquêmico transitório. As avaliações neuropsicológicas demonstraram que havia extenso prejuízo cognitivo no primeiro caso, em contraste com comprometimento leve no segundo. Baixas pontuações nas funções de atenção visual, memória operacional, linguagem, flexibilidade cognitiva, habilidades sensório-motora, visoespacial e viso-construtiva. Rebaixamento intelectual e no desempenho acadêmico foram encontrados no paciente que sofreu o acidente isquêmico. A criança que foi acometida por ataque isquêmico transitório apresentou dispraxia motora e oromotora, diminuição da atenção visual e memória verbal. Estes achados corroboram com os dados encontrados na literatura e reforçam a relevância de conhecer a tipologia destas alterações para intervir precocemente na deficiência cognitiva, minimizando as repercussões no desenvolvimento cognitivo, acadêmico e psicossocial.This is a case study of two children with sickle cell anemia and neurological complications. An extensive series of neuropsychological tests - NEPSY was used in the evaluation of the children. One child had suffered an ischemic stroke with left hemiparesis and the other, transient ischemic attack. The neuropsychological assessment showed extensive cognitive damage in the first case, in contrast to mild impairment in the second. Low scores were found for tasks of visual attention, operational memory, language, cognitive flexibility and for sensory-motor, visuospatial and visuoconstructive skills. Low intellectual and academic performance was found in the patient who suffered ischemic stroke. The child who suffered transient ischemic attack showed motor and oromotor dyspraxia, and decreased visual attention

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

This study examined the prevalence of high blood pressure, heart disease, and medical diagnoses in relation to blood disorders, among 6,329 adolescent students (age 15 to 18 years) who reside in the United Arab Emirates (UAE). Findings indicated that the overall prevalence of high blood pressure and heart disease was 1.8% and 1.3%, respectively. Overall, the prevalence for thalassemia, sickle-cell anemia, and iron-deficiency anemia was 0.9%, 1.6%, and 5%, respectively. Bivariate analysis revealed statistically significant differences in the prevalence of high blood pressure among the local and expatriate adolescent population in the Emirate of Sharjah. Similarly, statistically significant differences in the prevalence of iron-deficiency anemia were observed among the local and expatriate population in Abu Dhabi city, the western region of Abu Dhabi, and Al-Ain. Multivariate analysis revealed the following significant predictors of high blood pressure: residing in proximity to industry, nonconventional substance abuse, and age when smoking or exposure to smoking began. Ethnicity was a significant predictor of heart disease, thalassemia, sickle-cell anemia, and iron-deficiency anemia. In addition, predictors of thalassemia included gender (female) and participating in physical activity. Participants diagnosed with sickle-cell anemia and iron-deficiency anemia were more likely to experience different physical activities.

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

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

Full Text Available O lúpus eritematoso sistêmico (LES é uma doença tipicamente multigênica e multifatorial, com grande complexidade clínica e fisiopatológica. As causas do LES não são totalmente conhecidas, mas sabe-se que fatores ambientais e genéticos estão envolvidos. Dentre as várias manifestações clínicas observadas em pacientes com LES, as anemias chamam a atenção principalmente quando se observa nesse estudo uma prevalência de 52,5% dos pacientes com índices hematimétricos sugestivos de anemias. Embora a anemia geralmente já seja observada em pacientes com LES, estudos sobre a prevalência de anemias hereditárias, especialmente as hemoglobinopatias na população com LES, não têm sido conduzidos. O objetivo desse trabalho foi o de avaliar a prevalência das hemoglobinopatias e talassemia em pacientes portadores de LES. Para isso, foram estudadas 80 amostras de sangue de pacientes portadores de lúpus atendidos no ambulatório do Hospital das Clínicas de Goiânia. Foram utilizados testes laboratoriais não moleculares para a detecção das hemoglobinopatias. A freqüência das alterações da hemoglobina foi de 10,0%, encontradas em oito pacientes. Dessas alterações, a mais prevalente foi a talassemia alfa, encontrada em quatro pacientes, correspondendo a uma freqüência de 5,0% da população estudada. Depois, foi o heterozigoto para a hemoglobina S, encontrada em dois pacientes, correspondendo a 2,5% da população, e também outro heterozigoto para a hemoglobina C, encontrada em um paciente, correspondendo a 1,25%, e um paciente com beta talassemia menor, correspondendo a 1,25%. Nenhum caso de homozigose foi encontrado no presente estudo. Este trabalho demonstrou que não houve diferença na prevalência dos distúrbios da hemoglobina entre a população em geral e os portadores de LES.Systemic lupus erythematosus (SLE is a typically multigenic and multifatorial disease with remarkable clinical and pathogenic complexities.

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.

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

Full Text Available Transient Ischemic Attack Caused by Iron Deficiency Anemia Transient ischemic attacks are episodes of transient focal ischemia involving the brain or brainstem. They are commonly two to thirty minutes in duration and lasting less than 24 hours. Anemia of iron deficiency isn’t frequently cause for transient ischemic attack. It has been reported as a risk factor for childhood ischemic strokes. In the iron deficiency anemia, T‹A may develop as result of hypercoagulable state and increased viscosity that is caused by anemic hypoxia that is result of reduce hemoglobine level, seconder thrombosis and microcytose As iron deficiency anemia has been reported so rarely in adult patients with transient ischemic attacks as a cause, we aimed to discuss the clinical and outcome features of two cases with iron deficiency anemia and transient ischemic attacks in this study. Materials and methods: Routine neurologic examination, biochemical screen, serological tests, vasculitic markers, thyroid function tests, vitamin B 12 level, cranial imaging, vertebral carotid doppler USG examination was conducted in the two patients. Anemia of iron deficiency was found as the only risk factor for TIA and the two patients were treated with replacement of iron and antiagregan therapy. Neurological examination revealed no abnormality through the two years of follow-up. The iron deficiency anemia may be cause of many neurologic problems such a irritability, lethargy, headache, development retardation except from T‹A. In the iron deficiency anemia, early diagnosis and treatment is important

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

Full Text Available A anemia falciforme é a doença genética de maior prevalência na população brasileira e comumente apontada como uma questão de saúde pública. O Brasil tem investido na elaboração de ações no campo da anemia falciforme, dentre as quais se encontram ações educativas. Este artigo analisa alguns dos impactos causados pelas informações contidas no folheto educativo Anemia falciforme: um problema nosso, do Ministério da Saúde. O objetivo foi descrever e analisar como, após a leitura do folheto, pessoas com diferentes níveis de escolaridade compreendem a distinção entre traço e a anemia falciforme e como mensuram o risco reprodutivo de casais com o traço falciforme. A coleta de dados foi realizada por meio de questionário aplicado com 1.007 pessoas, em 11 cidades brasileiras, no período de junho a setembro de 2003. Os dados revelam que: a educação formal é fator fundamental para compreensão do folheto; a confusão entre traço e anemia falciformes permanece apesar de o folheto destacar a diferença entre ambas; e o risco reprodutivo de nascimento de futuras crianças com anemia falciforme é sobrevalorizado. Os resultados apontam para a tensão entre estratégias de prevenção de doenças e de promoção da autonomia reprodutiva, uma característica da nova genética.The sickle cell anaemia is the genetic disease with the highest prevalence in Brazil and it is considered a public health matter.

To update the prevalence of anemia and its trend in Mexican women of childbearing age over the past 13 years using information from the National Health and Nutrition Survey 2012 and 2006 (ENSANUT 2012 and ENSANUT 2006, respectively) and from the National Nutrition Survey 1999 (ENN 99). Data came from three national probabilistic surveys, representative at regional and rural / urban level. Hemoglobin (Hb) in women was measured using a HemoCue photometer and classified as anemia according to the WHO criteria. Frequencies and CI95% were estimated for each survey (ENSANUT 2012, ENSANUT 2006 and ENN 99) as well as percentage changes in anemia prevalence among pregnant and non-pregnant women in this survey sequence. The national prevalence of anemia in 2012 in non-pregnant women was 11.6% and in pregnant women was 17.9%. Between 1999 and 2012, a 10 percentage point (pp) decreasing in anemia prevalence was observed in the first ones and a 13.5 pp in the second ones. Although it has declined in the past 13 years, anemia in women of childbearing age remains as a serious public health problem. It is considered necessary to design strategies to prevent iron deficiency and for the early detection of anemia in women.

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 Objective: The prevalence of anemia in HIV infected patients has not been well characterized in Iran. This study aimed to describe the prevalence of anemia and related factors in HIV positive patients. Materials and Methods: In a cross-sectional study, anemia prevalence and risk factors of 212 HIV positive patients were assessed, at the behavioral disease consulting center in Isfahan. The relationship between anemia, demographic variables, and clinical histories were analyzed. Mild to moderate anemia was defined as hemoglobin 8-13 g/dL for men and 8-12 g/dL for women. Severe anemia was defined as hemoglobin, 8 g/dL. Results: A total of 212 HIV positive patients with a mean±SD age of 36.1 ± 9.1 years were assessed. We found that hemoglobin levels were between 4.7 and 16.5 gr/dL. In this study, the overall prevalence of anemia was 71%, with the majority of patients having mild to moderate anemia. Mild to moderate anemia and severe anemia occurred in 67% and 4% of patients, respectively. The mean absolute CD4 count was 348 ± 267.8 cells/cubic mm. Sixty one of 212 patients were at late stage of HIV infection (males=51 and female=10. Of the 212 HIV positive patients enrolled, 17 (8% had a positive history of tuberculosis. We found a strong association between anemia and death. Conclusion: Normocytic anemia with decreased reticulocyte count was the most common type of anemia in overall. Prevalence of anemia in this study is relatively higher than other similar studies. Such a high prevalence of anemia needs close monitoring of patients on a zidovudine-based regimen. Better screening for anemia and infectious diseases, and modified harm reduction strategy (HRS for injection drug users are primary needs in HIV seropositive patients.

Many studies have documented a high prevalence of anemia among tuberculosis (TB) patients and anemia at TB diagnosis has been associated with an increased risk of death. However, little is known about the factors contributing to the development of TB-associated anemia and their importance in TB disease progression. Data from a randomized clinical trial of micronutrient supplementation in patients with pulmonary TB in Tanzania were analyzed. Repeated measures of anemia with iron deficiency, anemia without iron deficiency, and iron deficiency without anemia were assessed as risk factors for treatment failure, TB recurrence, and mortality. The prevalence of anemia (hemoglobin iron deficiency (mean corpuscular volume , 80 fL). We found no evidence of an association between anemia (with or without iron deficiency) or iron deficiency without anemia at baseline and the risk of treatment failure at 1 mo after initiation. Anemia without iron deficiency was associated with an independent, 4-fold increased risk of TB recurrence [adjusted RR = 4.10 (95% CI = 1.88, 8.91); P Iron deficiency and anemia (with and without iron deficiency) were associated with a 2- to nearly 3-fold independent increase in the risk of death [adjusted RR for iron deficiency without anemia = 2.89 (95% CI = 1.53, 5.47); P = 0.001; anemia without iron deficiency = 2.72 (95% CI = 1.50, 4.93); P = 0.001; iron deficiency anemia = 2.13 (95% CI = 1.10, 4.11); P = 0.02]. Efforts to identify and address the conditions contributing to TB-associated anemia, including iron deficiency, could play an important role in reducing morbidity and mortality in areas heavily affected by TB.

2005-12-29

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

Iron deficiency and anemia are changes often associated with obesity. Bariatric surgery is responsible for increasing the iron loss and reducing its absorption. The objective of this study was to evaluate anemia and iron deficiency before and after bariatric surgery and to relate them to possible predisposing factors. A retrospective study was conducted on obese patients submitted to open Roux-en-Y gastric bypass, in which clinical and laboratory data were obtained up to 48 months postoperatively. Patients were divided into groups according to the presence or absence of anemia and to the presence or absence of iron deficiency (even without anemia), and all data were compared between these groups. Preoperatively, 21.5% of patients had anemia and 20% had iron deficiency. The number of patients with anemia did not vary through the 4 years of the study, but ferritin levels significantly decreased with time (Panemia. Female gender was a variable associated with a greater incidence of iron deficiency. Anemia and iron deficiency are frequent in obese patients and must be treated before surgery. Medical and nutritional surveillance is important in the postoperative period of bariatric surgery. Management of each condition must be directed at correcting the 2 major sources of iron deficiency and anemia: food intolerance (mostly meat intolerance) and losses (frequently due to menstruation). These are the factors more related to iron deficient anemia. Copyright © 2014 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

Anemia, iron deficiency anemia (IDA), and iron deficiency (ID) are highly prevalent in renal transplant recipients (RTR). Anemia is associated with poor outcome, but the role of ID is unknown. Therefore, we aimed to investigate the association of ID, irrespective of anemia, with all-cause mortality in RTR. Cox regression analyses were used to investigate prospective associations. In 700 RTR, prevalences of anemia, IDA, and ID were 34%, 13%, and 30%, respectively. During follow-up for 3.1 (2.7-3.9) years, 81 (12%) RTR died. In univariable analysis, anemia [HR, 1.72 (95%CI: 1.11-2.66), P = 0.02], IDA [2.44 (1.48-4.01), P anemia with mortality became weaker after adjustment for ID [1.52 (0.97-2.39), P = 0.07] and disappeared after adjustment for proteinuria and eGFR [1.09 (0.67-1.78), P = 0.73]. The association of IDA with mortality attenuated after adjustment for potential confounders. In contrast, the association of ID with mortality remained independent of potential confounders, including anemia [1.77 (1.13-2.78), P = 0.01]. In conclusion, ID is highly prevalent among RTR and is associated with an increased risk of mortality, independent of anemia. As ID is a modifiable factor, correction of ID could be a target to improve survival. © 2016 The Authors.

To establish regional prevalences of anemia in pregnant women receiving care at public clinics in Peru in 2015 and identify high-prevalence district conglomerates. An ecological study was carried out on data from pregnant women with anemia registered on the Nutritional Status Information System (SIEN) who received care in 7703 public clinics in 2015. Regional and district prevalences of gestational anemia were calculated. District conglomerates with a high prevalence of gestational anemia were identified using the Moran Index. Information was gathered from 311,521 pregnant women distributed in 1638 districts in Peru. The national prevalence of anemia was 24.2% (95% confidence interval [95% CI]: 24.0-24.3%), the rural prevalence was 30.5%, and the urban prevalence was 22.0%. The regions of Huancavelica (45.5%; 95% CI: 44.2-46.7%), Puno (42.8%; 95% CI: 41.9-43.7%), Pasco (38.5%; 95% CI: 36.9-40.0%), Cusco (36.0%; 95% CI: 35.3-36.8%), and Apurímac (32.0%; 95% CI: 30.8-33.1%) had the highest prevalences of anemia. The local Moran Index identified 202 high-priority districts (hot spots) (12.3% of total; 44 urban and 158 rural) located in Ancash, Apurímac, Arequipa, Ayacucho, Cajamarca, Cusco, Huancavelica, Huánuco, Junín, La Libertad, Lima, Pasco, and Puno containing high-prevalence district conglomerates. Gestational anemia in Peru has its highest prevalence rates in rural and southern mountainous areas. The district conglomerates with high prevalence rates of gestational anemia coincide with the areas of high regional prevalence.

Anemia in toddlers may result from many disorders including excessive feeding with cow's milk. Another sequel of age-inadequate cow's milk nutrition may be gastric lactobezoar (GLB), a dense lump of coagulated milk and mucus in the stomach. 3 toddlers presented with a history of excessive intake of full cream cow's milk, abdominal distension, vomiting, dehydration, fatigue, marked pallor and tachycardia. Diagnostic imaging revea-led large GLBs as the likely origin of the abdominal symptoms. Laboratory evaluation showed severe anemia with depleted iron stores and signs of protein catabolism. Non-cow's milk-induced causes of anemia including defects of erythropoiesis, hemoglobin structure, RBC-enzymes and blood coagulation, hemolysis, immune disorders, infection, inflammation, extraintestinal hemorrhage, nephropathy were - according to the available data - unlikely to cause the anemia in our patients. Thus their anemia is thought to be due to age-inadequate cow's milk nutrition leading to 1) low intake, decreased absorption/bioavailability and increased intestinal loss of iron, and 2) GLB which induced blood loss following mechanical irritation of the gastric mucosa and vomiting causing high gastric pH and decrease in duodenal iron absorption. The anemia in our patients is due to both exaggerated feeding with cow's milk and adverse effects of GLBs. This hypothesis is supported by the finding that, after erythrocyte transfusion, iron substitution, age-adapted nutrition and GLB-dissolution, the anemia did not recur. We propose to include GLB in the differential diagnosis of anemia in cow's milk fed small children. © Georg Thieme Verlag KG Stuttgart · New York.

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.

The Fanconi anemia proteins participate in a canonical pathway that repairs cross-linking agent-induced DNA damage. Cells with inactivated Fanconi anemia genes are universally hypersensitive to such agents. Fanconi anemia-deficient hematopoietic stem cells are also hypersensitive to inflammatory cytokines, and, as importantly, Fanconi anemia macrophages overproduce such cytokines in response to TLR4 and TLR7/8 agonists. We questioned whether TLR-induced DNA damage is the primary cause of aberrantly regulated cytokine production in Fanconi anemia macrophages by quantifying TLR agonist-induced TNF-α production, DNA strand breaks, crosslinker-induced chromosomal breakage, and Fanconi anemia core complex function in Fanconi anemia complementation group C-deficient human and murine macrophages. Although both M1 and M2 polarized Fanconi anemia cells were predictably hypersensitive to mitomycin C, only M1 macrophages overproduced TNF-α in response to TLR-activating signals. DNA damaging agents alone did not induce TNF-α production in the absence of TLR agonists in wild-type or Fanconi anemia macrophages, and mitomycin C did not enhance TLR responses in either normal or Fanconi anemia cells. TLR4 and TLR7/8 activation induced cytokine overproduction in Fanconi anemia macrophages. Also, although TLR4 activation was associated with induced double strand breaks, TLR7/8 activation was not. That DNA strand breaks and chromosome breaks are neither necessary nor sufficient to account for the overproduction of inflammatory cytokines by Fanconi anemia cells suggests that noncanonical anti-inflammatory functions of Fanconi anemia complementation group C contribute to the aberrant macrophage phenotype and suggests that suppression of macrophage/TLR hyperreactivity might prevent cytokine-induced stem cell attrition in Fanconi anemia. © Society for Leukocyte Biology.

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

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

Epidemiology of aplastic anemia in Japanese radiological technicians

Kitabatake, Takashi; Watanabe, Tsuyoshi; Saito, Akira; Nakamura, Minoru.

1976-01-01

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.)

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.

Full Text Available Anemia in Indonesia is a public health problem. The prevalence still have a tendency to increase. The main antecedent factor for anemia is the lack of iron intake. The purpose of this analysis is to learn and find other factors besides iron. Sources of data were from the study of morbidity and disability of the Household Health Survey, 2001. The respondents were adolescents between 10-19 years of age. Data on social economic status, illness records, medicine consumption, physical activities and smoking habits were collected by interview during household visits. Data on anemia were identified from the results of hemoglobin determination by HemoCue. The nutrition status was found from the calculation of Body Mass Index. Data on energy consumption were taken from food expenditure for meal data from SUSENAS. Variable used for the purpose of this analysis were age, gender, smoking habit, alcohol drinking, breakfast, the use of time for physical activities, IMT, hemoglobin value and energy consumption. Data analyse were conducted in 3 stages,i.e., univariate, bivariate and multivariate analyse. Overall, the prevalence of anemia among adolescents was found to be 25.5%; 21% for adolescent boys and 30% for adolescent girls. Around 27.1% adolescents reside in the village and 22.6% in the city. Adolescents who consume > 70% energy from being suggested were around 38% respondents. Seventeen percent was classified as thinny adolescent based on IMT indicator. The result on bivariate analyse showed that respondents who were less educated have a significant relation (p < 0.05 with getting anemia (OR=3.8; 95% CI=1.9-7.2. Male adolescents have lower risk to get anemia (OR=0.6; 95% CI 0.5-7.3. Other variables that showed significant relation with anemia were smoking (OR 1.35; 95% CI 1-1.8, breakfast habit (OR 0.6 ;95% CI 0.4-0.9 and sufficient energy consumption (OR 0.7; 95% CI 0.6-0.9.

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

Full Text Available Objective. Pyelonephritis is a common infectious morbidity of pregnancy. Though anemia is commonly associated with pyelonephritis, there are little data describing the effect of pyelonephritis with anemia on pregnancy outcomes. The purpose of this study was to further assess the association of anemia with infectious morbidity and pregnancy complications among women with pyelonephritis. Study Design. We conducted a retrospective cohort study of pregnant women admitted to Duke University Hospital between July 2006 and May 2012 with pyelonephritis. Demographic, laboratory, and clinical data from the subject’s pregnancy and hospitalizations were analyzed. Patients with pyelonephritis and anemia (a hematocrit < 32 were compared to those without anemia. Descriptive statistics were used to compare the two groups. Results. 114 pregnant women were admitted with pyelonephritis and 45 (39.5% had anemia on admission. There was no significant difference in age, race, preexisting medical conditions, or urine bacterial species between patients with anemia and those without. Women with anemia were more likely to deliver preterm (OR 3.3 (95% CI 1.07, 11.4, . When controlling for race and history of preterm delivery, women with anemia continued to have increased odds of preterm birth (OR 6.0, CI 1.4, 35, . Conclusion. Women with pyelonephritis and anemia are at increased risk for preterm delivery.

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.

Association of mild anemia with cognitive, functional, mood and quality of life outcomes in the elderly: the "Health and Anemia" study.

Full Text Available BACKGROUND: In the elderly persons, hemoglobin concentrations slightly below the lower limit of normal are common, but scant evidence is available on their relationship with significant health indicators. The objective of the present study was to cross-sectionally investigate the association of mild grade anemia with cognitive, functional, mood, and quality of life (QoL variables in community-dwelling elderly persons. METHODS: Among the 4,068 eligible individuals aged 65-84 years, all persons with mild anemia (n = 170 and a randomly selected sample of non-anemic controls (n = 547 were included in the study. Anemia was defined according to World Health Organization (WHO criteria and mild grade anemia was defined as a hemoglobin concentration between 10.0 and 11.9 g/dL in women and between 10.0 and 12.9 g/dL in men. Cognition and functional status were assessed using measures of selective attention, episodic memory, cognitive flexibility and instrumental and basic activities of daily living. Mood and QoL were evaluated by means of the Geriatric Depression Scale-10, the Short-Form health survey (SF-12, and the Functional Assessment of Cancer Therapy-Anemia. RESULTS: In univariate analyses, mild anemic elderly persons had significantly worse results on almost all cognitive, functional, mood, and QoL measures. In multivariable logistic regressions, after adjustment for a large number of demographic and clinical confounders, mild anemia remained significantly associated with measures of selective attention and disease-specific QoL (all fully adjusted p<.046. When the lower limit of normal hemoglobin concentration according to WHO criteria was raised to define anemia (+0.2 g/dL, differences between mild anemic and non anemic elderly persons tended to increase on almost every variable. CONCLUSIONS: Cross-sectionally, mild grade anemia was independently associated with worse selective attention performance and disease-specific QoL ratings.

Sideropenic anemia in preschool children and risk factors

Directory of Open Access Journals (Sweden)

Stojanović Dušica

2006-01-01

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.

2012-01-01

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.

2017-01-01

To evaluate the prevalence of anemia, mean hemoglobin levels, and the main nutritional, demographic, and socioeconomic factors among Xavante children in Mato Grosso State, Brazil. A survey was conducted with children under 10 years of age in two indigenous Xavante communities within the Pimentel Barbosa Indigenous Reserve. Hemoglobin concentration levels, anthropometric measurements, and socioeconomic/demographic data were collected by means of clinical measurements and structured interviews. The cut-off points recommended by the World Health Organization were used for anemia classification. Linear regression analyses with hemoglobin as the outcome and Poisson regression with robust variance and with the presence or absence of anemia as outcomes were performed (95%CI). Lower mean hemoglobin values were observed in children under 2 years of age, without a significant difference between sexes. Anemia was observed among 50.8% of children overall, with the highest prevalence among children under 2 years of age (77.8%). Age of the child was inversely associated with the occurrence of anemia (adjusted PR = 0.60; 95%CI 0.38-0.95) and mean hemoglobin values increased significantly with age. Greater height-for-age z-score values reduced the probability of having anemia by 1.8 times (adjusted PR = 0.59; 95%CI 0.34-1.00). Presence of another child with anemia within the household increased the probability of the occurrence of anemia by 52.9% (adjusted PR = 1.89; 95%CI 1.16-3.09). Elevated levels of anemia among Xavante children reveal a disparity between this Indigenous population and the national Brazilian population. Results suggest that anemia is determined by complex and variable relationships between socioeconomic, sociodemographic, and biological factors.

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.

2009-01-01

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

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.

Fanconi anemia proteins in telomere maintenance.

Science.gov (United States)

Sarkar, Jaya; Liu, Yie

2016-07-01

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

Kaiser, A; Meier, H P; Straub, R; Gerber, V

2009-04-01

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

Aldehyde dehydrogenase 2 in aplastic anemia, Fanconi anemia and hematopoietic stem cells.

Science.gov (United States)

Van Wassenhove, Lauren D; Mochly-Rosen, Daria; Weinberg, Kenneth I

2016-09-01

Maintenance of the hematopoietic stem cell (HSC) compartment depends on the ability to metabolize exogenously and endogenously generated toxins, and to repair cellular damage caused by such toxins. Reactive aldehydes have been demonstrated to cause specific genotoxic injury, namely DNA interstrand cross-links. Aldehyde dehydrogenase 2 (ALDH2) is a member of a 19 isoenzyme ALDH family with different substrate specificities, subcellular localization, and patterns of expression. ALDH2 is localized in mitochondria and is essential for the metabolism of acetaldehyde, thereby placing it directly downstream of ethanol metabolism. Deficiency in ALDH2 expression and function are caused by a single nucleotide substitution and resulting amino acid change, called ALDH2*2. This genetic polymorphism affects 35-45% of East Asians (about ~560 million people), and causes the well-known Asian flushing syndrome, which results in disulfiram-like reactions after ethanol consumption. Recently, the ALDH2*2 genotype has been found to be associated with marrow failure, with both an increased risk of sporadic aplastic anemia and more rapid progression of Fanconi anemia. This review discusses the unexpected interrelationship between aldehydes, ALDH2 and hematopoietic stem cell biology, and in particular its relationship to Fanconi anemia.

Lin, Tiffany F; Huang, James N; Cash, Haley L

2017-12-01

Anemia can be an indicator of poor nutrition and health, and it can have significant consequences. Children are disproportionately affected by anemia. This comprehensive review summarizes the available literature on anemia prevalence in young children in the islands of the Oceania region. The anemia prevalence, the criteria used for diagnosis, the date the data was reported, and the types of samples collected were reviewed. Anemia prevalence estimates were reported for eighteen of the Pacific Island Jurisdictions. From the fifteen data sources that were evaluable, anemia prevalence ranged from 12.3% to over 70%. A major limitation in the data is a lack of representative primary data from many of the jurisdictions in the region. Prevalance estimates reported for those jurisdictions are estimated by regression analysis from the World Health Organization (WHO). Moreover, the primary data available does not use standardized reporting criteria. Nevertheless, this review serves as a new baseline for further investigations on the prevalence of anemia and a baseline for evaluating public health prevention and treatment measures to detect and improve anemia prevalence in the Pacific.

Management of Anemia in Patients with Inflammatory Bowel Disease (IBD).

Anemia is the most common complication as well as an extra intestinal manifestation of inflammatory bowel disease (IBD). It is associated with a significant impact on patient's quality of life (QoL); as well it represents a common cause of frequent hospitalization, delay of hospital inpatient discharge and overall increased healthcare burden. In spite of all these, anemia is still often underdiagnosed and undertreated. Our aim in this review is to provide a pathway for physicians to help them achieve early diagnosis as well as timely and appropriate treatment of anemia which in turn would hopefully reduce the prevalence and subsequent complications of this condition among IBD patients. The etiology of anemia among IBD patients is most commonly due to iron deficiency anemia (IDA) followed by anemia of chronic disease. Despite this, more than a third of anemic ulcerative colitis (UC) patients are not tested for IDA and among those tested and diagnosed with IDA, a quarter are not treated with iron replacement therapy. A new algorithm has been validated to predict who will develop moderate to severe anemia at the time of UC diagnosis. While oral iron is effective for the treatment of mild iron deficiency-related anemia, the absorption of iron is influenced by chronic inflammatory states as a consequence of the presence of elevated levels of hepcidin. Also, it is important to recognize that ferritin is elevated in chronic inflammatory states and among patients with active IBD, ferritin levels less than 100 are considered to be diagnostic of iron deficiency. Newer formulations of intra-venous (IV) iron have a good safety profile and can be used for replenishment of iron stores and prevention of iron deficiency in the future. Routine screening for anemia is important among patients with IBD. The cornerstone for the accurate management of anemia in IBD patients lies in accurately diagnosing the type of anemia. All IBD patients with IDA should be considered appropriate for

Full Text Available JUSTIFICATIVA E OBJETIVOS: A plasmaféresis é a técnica de tratamento de escolha para pacientes com anemia hemolítica grave. Uma de suas conseqüências é a depleção de colinesterase plasmática, o que interfere na metabolização de alguns bloqueadores neuromusculares de uso corrente na prática anestesiológica. RELATO DO CASO: Paciente com 26 anos, estado físico ASA IV, gestação de 30 semanas e 3 dias, portadora de anemia falciforme, traço talassêmico e alo-imunização para antígenos de alta freqüência. Apresentou crise de falcização, sendo transfundida com derivado sangüíneo incompatível. Evoluiu com hemólise maciça, sendo admitida com hemoglobina de 3 g/dL e hematócrito de 10%, icterícia intensa, taquicardia, apatia e descoramento. Na avaliação hematológica concluiu-se ser situação de inexistência de sangue compatível para transfusão. Foi tratada com corticoterapia, imunoglobulinas e plasmaféresis. No segundo dia de internação, evoluiu com insuficiência renal aguda e edema pulmonar agudo, piora do estado geral e instabilidade hemodinâmica. Indicada a resolução da gestação em decorrência do quadro clínico da paciente e do sofrimento fetal agudo que se sobrepôs. A paciente foi admitida na sala de operações consciente, dispnéica, pálida, ictérica, SpO2 de 91% em ar ambiente, freqüência cardíaca de 110 bpm e pressão arterial de 110 x 70 mmHg, em uso de dopamina (1 µg.kg-1.min-1 e dobutamina (10 µg.kg-1.min-1. Optou-se por anestesia geral balanceada, com alfentanil (2,5 mg, etomidato (14 mg e atracúrio (35 mg e isoflurano. Não se observou intercorrências anestésico-cirúrgicas. Ao final, a paciente foi encaminhada à UTI, sob intubação orotraqueal, e em uso de drogas vasoativas, tendo sido extubada após 3 horas. CONCLUSÕES: Este caso mostrou-se um desafio para a equipe, visto que a paciente apresentava instabilidade hemodinâmica e alteração do coagulograma, condições que contra

Anemia of chronic disease is the more frequent type of anemia seen in patients with chronic idiopathic neutropenia of adults.

This study describes the frequency and the type of anemia seen in patients with nonimmune chronic idiopathic neutropenia of adults (NI-CINA). We found that NI-CINA patients had low hemoglobin levels and increased serum concentrations of erythropoietin (EPO), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta (IL-1beta). The hemoglobin levels correlated positively with the number of circulating neutrophils and inversely with the levels of EPO and TNF-alpha but not of IL-1beta. Anemia, defined as the reduction of the hemoglobin below 12.0 g/dl for women and 13.3 g/dl for men, was found in 23 out of 148 patients studied, a proportion of 15.5%. Two of the anemic patients had iron deficiency anemia (8.7%), 11 had anemia of chronic disease (ACD; 47.8%) presenting with normal or slightly reduced erythrocytic indices, low serum iron, and increased serum ferritin, and the remaining ten had anemia of undefined pathogenesis (AUP; 43.5%) with normal or slightly decreased erythrocytic indices, serum iron ranging from 43 to 88 microg/dl, and ferritin values ranging from 12 to 50 ng/ml. We conclude that ACD is the more frequent type of anemia seen in patients with NI-CINA, and that pro-inflammatory cytokines, notably TNF-alpha, may be involved in the pathogenesis of both ACD and AUP, given that serum levels of the cytokine were significantly increased and that the EPO response to anemia was blunted in these patients. These findings further support our previously reported suggestion for the possible existence, in NI-CINA patients, of an unrecognized low-grade chronic inflammatory process that may be involved in the pathogenesis of the disorder.

Full Text Available Estudamos 25 casos escolhidos de Ancylostomose, procurando determinar quaes os factores que provocam a regeneração hematica, procurando o mechanismo desta regeneração e o desenvolver do processo anemiante. Preferimos seleccionar um numero pequeno de casos e acompanhal-o durante um largo tempo, observando alguns delles durante 1 a 1 anno e meio. A parte hematologica constou, além de 568 exames rotineiros (numeração das hematias, dosagem de Hb., determinação do hematocrito, e na maioria das vezes, determinação da taxa de reticulocytose verificação do aspecto morphologico do sangue em esfregaços, de pesquisas sobre a resistencia globular, sobre a taxa de proteinas no sôro, e em alguns casos, contagem de plaquetas, determinação da viscosidade, etc. Empregamos para estas pesquizas os methodos usuaes, a não ser na determinação da resistencia globular, para a qual descrevemos detalhadamente um processo pouco usado. Durante todo o transcorrer das observações, a actividade biologica dos helminthos parasitos foi controlada por numerosos exames de fezes, que constavam da pesquiza de ovos eliminados, de reacções chimicas que demonstrassem a presença de sangue. Exames de urina foram feitos periodicamente e outros exames foram praticados quando sobrevinha uma complicação ou qualquer facto inesperado. Observamos nos casos graves da doença, uma anemia de caracteristicas fixas. E' uma anemia hypochromica, microcytica, fracamente regenerativa. Verificamos que a degeneração dos indices hematicos, isto é, que o grau de hypochromia e micocytose, não se apresentam nestes casos extremos de modo variavel, mas sim, de maneira particularmente constante; e verificamos mais que estes indices assim degenerados (Ind. Vol. 53 uc., Ind. Hb. 13 yy, Ind. Sat. 23% tambem são encontrados segundo observações de outros autores, em varias anemias hypochromicas humanas ou de outros mammiferos. No exame de esfregaços, são extremamente raros ou mesmo

Syngeneic transplantation in aplastic anemia

DEFF Research Database (Denmark)

Gerull, Sabine; Stern, Martin; Apperley, Jane

2013-01-01

Aplastic anemia is usually treated with immunosuppression or allogeneic transplant, depending on patient and disease characteristics. Syngeneic transplant offers a rare treatment opportunity with minimal transplant-related mortality, and offers an insight into disease mechanisms. We present here...... a retrospective analysis of all syngeneic transplants for aplastic anemia reported to the European Group for Blood and Marrow Transplantation. Between 1976 and 2009, 88 patients received 113 transplants. Most transplants (n=85) were preceded by a conditioning regimen, 22 of these including anti-thymocyte globulin...
