    Full Text Available O transplante de medula óssea é um tratamento eficaz para pacientes com anemia aplástica severa (AAS e é a modalidade terapêutica de escolha para pacientes jovens com doador aparentado HLA idêntico. A rejeição é uma importante complicação do transplante de medula, que, independentemente do tipo de tratamento imunossupressor pré e pós-transplante, ocorre em 55% a 60% dos pacientes. O serviço de TMO da Universidade Federal do Paraná (UFPR acumula a experiência de 178 casos de AAS transplantados no período de 1993 a 2001, usando como condicionamento tanto a ciclofosfamida (CFA como a combinação desta ao bussulfano (CFA + BU. Dentre eles, 39 apresentaram rejeição ou falha de pega. Dos pacientes condicionados com ciclofosfamida, 24 (46% apresentaram rejeição, sendo 3 (6% com falha primária de pega (FPP e 21 (40% com pega transitória (PT. Entre os pacientes condicionados com BU+CFA, 15 (12% apresentaram rejeição, sendo 4 (3% com FPP e 11 (9% com pega transitória. Os pacientes condicionados com ciclofosfamida (200 mg/kg que apresentaram rejeição tiveram uma sobrevida global alta (aproximadamente 80%, pois conseguiram ser resgatados por um novo transplante ou pelo tratamento imunossupressor com ciclosporina. A sobrevida dos pacientes politransfundidos condicionados com a associação de ciclofosfamida e bussulfano foi de aproximadamente 35%.Bone marrow transplantation is an effective therapy for severe aplastic anemia and is generally considered the preferable treatment for young patients who have an HLA (Human Leukocyte Antigen identical sibling donor. Recent studies report 55% to 80% extended survival. Graft failure owing to rejection or others causes remains an important life-threatening complication following allogeneic bone marrow transplantation for aplastic anemia. It occurs in 55% to 60% of patients receiving HLA identical transplants, using different immunosuppressive therapies before and after transplant. The BMT

    Full Text Available RESUMO Objetivos: Definir frequência de doença por citomegalovírus dentre pacientes transplantados renais na unidade de terapia intensiva nos quais houve a suspeita desta complicação; identificar fatores predisponentes e possível impacto na evolução clínica. Métodos: Estudo retrospectivo observacional, no qual foram incluídos pacientes transplantados renais acima de 18 anos, internados por quaisquer motivos em uma unidade de terapia intensiva, com pelo menos uma coleta de antigenemia ou reação em cadeia da polimerase para citomegalovírus durante internação. Doença por citomegalovírus foi definida por antigenemia positiva ou reação em cadeia da polimerase acima de 500 cópias/mL, na presença de sintomas, no contexto clínico apropriado, conforme julgamento do médico assistente. Resultados: Foram incluídos 99 pacientes (idade: 53,4 ± 12,8 anos, 71,6% homens. A doença por citomegalovírus foi diagnosticada em 39 pacientes (39,4%. Sintomas respiratórios (51%, piora clínica inespecífica (20% ou sintomas gastrintestinais (14% foram os principais motivos para coleta de exames. O tempo de transplante foi menor naqueles com doença por citomegalovírus em relação àqueles sem este diagnóstico (6,5 meses e 31,2 meses; p = 0,001, bem como uso de pulsoterapia nos últimos 6 meses (41% e 16,9%; p = 0,008 e uso prévio de timoglobulina no último ano (35,9% e 6,8%; p < 0,001. No modelo de regressão logística, somente o tempo de transplante e o uso de timoglobulina associaram-se à maior frequência de citomegalovírus. Não houve diferença na evolução clínica entre pacientes com ou sem doença por citomegalovírus. Conclusão: Em pacientes transplantados renais com suspeita de doença por citomegalovírus, a prevalência foi alta. O tempo de transplante menor que 6 meses e o uso de timoglobulina no último ano devem aumentar a suspeita do intensivista para esta complicação.

    Full Text Available São registrados três casos de feo-hifornicose subcutânea em transplantados renais provocados pela Exophiala jeanselmei (Langeron McGinnis et Padhye 1977, fungo demácio capaz, também, de produzir raramente eumicetoma de grãos pretos. Este fungo, segundo KWON-CHUNG & BENNETT, 1992(27 é antigenicamente muito heterogêneo, sendo identificados até o presente momento três sorotipos com subgrupos dentro de cada um deles. A feo-hifomicose subcutânea vem se tornando cada vez mais freqüente em transplantados renais, submetidos a terapêutica imunodepressora. Como a Exophiala jeanselmei já foi isolada do meio ambiente, torna-se dificil explicar a patogenia desses casos por um despertar ou reativação de processos quiescentes. Os Autores fizeram ampla revisão da literatura, registrando principalmente os casos de feo-hifomicose publicados no Brasil. Sugerem também, eventual ação fungistática da ciclosporina A sobre a Exophiala jeanselmei.We report three cases of subcutaneous phaeohy-phomycosis due to Exophiala jeanselmei (Langeron McGinnis et Padhye 1977, in kidney transplant patients. Exophiala jeanselmei is a dematious fungus having also ability to rarely procedure eumycetoma (black grains. According to KWON-CHUNG & BENNETT (199227 such fungus is antigenically very heterogeneous, since so far three serotypes have been identified; each serotype including subgroups. Subcutaneous phaeohyphomycosis is becoming more and more frequent in kidney transplant patients submitted to an immunosupressive treatment. As Exophiala jeanselmei has already been isolated from the environment it becomes difficult to explain the pathogenicity of these cases by a reactivation of quiescent processes. The authors suggest an occasional fungistatic action of cyclosporine A upon Exophiala jeanselmei. A review of the literature was carried out with the report mainly of cases published in Brazil.

    Full Text Available From January 1988 to January 1989 all the heart transplant and bone marrow recipients at the Instituto do Coração of the Hospital das Clínicas of the University of São Paulo Medical School were studied for the incidence and morbidity associated with herpesviruses infections after transplantation. Five bone marrow and 5 heart transplant recipients were followed for a mean of 4.2 months post-transplantation. All the patients were seropositive for cytomegalovirus (CMV before admission and 80% experienced one or more recurrences during the observation period. Of the 12 episodes of CMV infection, that were identified in this study, 83% were accompanied by clinical or laboratory abnormalities. However, there was only one case of severe disease. The overall incidence of infection for herpes simplex (HSV was 50%. Although most of HSV reactivations were oral or genital, one case of HSV hepatitis occurred. One of the 6 episodes of HSV infections that were treated with acyclovir showed an unsatisfactory response and was successfully managed with ganciclovir. All the individuals had anti-varicella zoster virus antibodies, but none of them developed infection. The study emphasizes the importance of active diagnostic surveillance of herpesvirus infections in transplant patients. Both CMV and HSV reactivations showed high incidence and important morbidity and thus, deserve prophylactic therapy.De janeiro de 1988 a janeiro de 1989 todos os pacientes submetidos a transplante de coração ou de medula óssea no Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foram estudados quanto à incidência e morbidade das infecções pós-transplante causadas por vírus do grupo herpes. Cinco recipientes de medula óssea e 5 transplantados cardíacos foram observados por um período médio de 4.2 meses após o transplante.

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

    Full Text Available Os autores relatam um caso de paniculite criptocócica em paciente transplantado renal inicialmente tratado como celulite bacteriana. O diagnóstico definitivo só foi possível pela impressão clínica dermatológica confirmada pelo exame micológico. O tratamento foi realizado a princípio com anfotericina B e posteriormente com fluconazol, considerando-se as interações das drogas imunossupressoras utilizadas para evitar rejeição. A regressão clínica foi alcançada no sexto mês de tratamento, que, no entanto, foi mantido por 12 meses. São feitas considerações a respeito dessa forma rara de criptococose cutânea em transplantado de órgão sólido e suas implicações diagnósticas e terapêuticas.The authors report a case of cryptococcal panniculitis in a renal transplant recipient,which was initially mistaken for bacterial cellulitis. Dermatological evaluation and laboratory studies led to the definitive diagnosis. Treatment was started with amphotericin B, followed by oral fluconazol, taking into consideration their interactions with the immunossupressive drugs. Even though clinical improvement was attained after six months, treatment was maintained during a whole year. We discuss this rare presentation of cutaneous cryptococcosis in a solid organ transplant recipient, as well as its diagnosis and therapy.

En Cuba se está trabajando desde el año 1987 en el desarrollo de programas de intervención para la prevención de la anemia por deficiencia de hierro en la población, pero a pesar de todo el esfuerzo, no se han obtenido los impactos esperados, y existen diversos factores que pueden estar incidiendo en ello y que pueden sinergizarse. Evidencias científicas nacionales muestran que la baja prevalencia de lactancia materna, el escaso consumo de frutas y vegetales y la deficiencia vitamínica, ejercen influencia en la prevalencia de la anemia en Cuba. El parasitismo intestinal y la infección con H. pylori no están asociados con la prevalencia de anemia en el país. La obesidad e inflamación crónica a bajo tenor requerirían de estudios epidemiológicos que describan las posibles asociaciones entre estos factores.Anemia is a global health problem affecting both developed and developing countries. The causes of anemia may be multifactorial, and several of them are often present at the same time. The main cause of anemia is the low intake of foods with adequate sources of iron both in quantity and quality. Work is being done in Cuba since the year 1987 aimed at developing intervention programs for the prevention of iron deficiency anemia in the population, but despite the great effort, the expected impact has not been achieved, due to the combined influence of various factors. National scientific evidence shows that the low incidence of breastfeeding, the low intake of fruits and vegetables, as well as vitamin deficiency, have an influence on the prevalence of anemia in Cuba.

    Full Text Available Os Autores registram caso de histoplasmose generalizada em paciente transplantado com rim de doador não aparentado. Além da infecção fúngica diagnosticada sorologicamente e pela histopatologia, a autópsia revelou cirrose hepática macro e micronodular, de provável etiologia viral (vírus B, hepatocarcinoma, depleção linfóide do baço e glomerulopatia de transplante. Revendo a literatura sobre o assunto, chegam à conclusão de que, provavelmente, com a imunodepressão medicamentosa, as lesões pulmonares por reinfecção endógena foram as primeiras a aparecer sob a forma de uma histoplasmose pulmonar crônica.The Authors report a case of disseminated histoplasmosis in a patient during the course of non related kidney transplant. Besides the fungal infection detected by serology and histopathology, autopsy showed macro and micro-nodular hepatic cirrhosis, probably of viral etiology (B virus, hepatocarcinoma, lymphoid depletion of the spleen and transplant glomerulonephritis. After concerning literature review the Authors conclude that probably due to immunosuppressive therapy, the pulmonary lesions by endogenous reinfection were the first to appear under the form of a chronic pulmonary histoplasmosis.

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

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

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

    Full Text Available BACKGROUND: The increasing in the number of kidney transplant recipients has favored, more frequently than before, the emergence of dermatoses and warranted their study through subsequent publications. OBJECTIVES: to evaluate the frequency of dermatoses in kidney transplant recipients. METHODS: kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010. RESULTS: 53 patients (28 males and 25 females, aged between 22 and 69 (mean age = 45 years were evaluated. Most of them came from the cities of Ceilândia, Samambaia and São Sebastião/DF, and had already been transplanted for 5 to 10 years before (37.7%; 62.3% were recipients of living donors and 83% were prednisone-treated. The most prevalent dermatoses were of fungal (45.3% and viral (39.6% etiologies. Among the non-melanoma malignant neoplasms, the basal cell carcinoma prevailed (six cases, in spite of the low incidence. Concerning fungal dermatoses, 12 cases of onychomycosis, five of pityriasis versicolor and four of pityrosporum folliculitis were reported. For diagnosis, in most cases (64.2%, laboratory examinations (mycological and histopathological were performed. CONCLUSION: cutaneous manifestations in kidney transplant recipients are generally secondary to immunosuppression. The infectious dermatoses, especially those of fungal origin, are frequently found in kidney transplant recipients and their occurrence increases progressively according to the time elapsed from the transplantation, which makes follow-up important. FUNDAMENTOS: o crescente aumento do número dos transplantados renais tem favorecido o aparecimento mais frequente das dermatoses e permitido o estudo em sucessivos trabalhos. OBJETIVOS: avaliar a frequência das dermatoses em pacientes transplantados renais.

    Full Text Available FUNDAMENTO: O Transplante Cardíaco (TC é uma alternativa para os indivíduos com doença cardíaca terminal. Na evolução pós-transplante, a ocorrência de episódios de Rejeição Cardíaca (RC é evento frequente que aumenta a morbimortalidade, sendo necessário o emprego de exame não invasivo com boa acurácia para seu diagnóstico, pois a Biópsia Endomiocárdica (BEM não é um procedimento isento de complicações. OBJETIVO: Comparar parâmetros obtidos com o princípio Doppler, entre os pacientes transplantados com RC (TX1 e os pacientes transplantados sem rejeição (TX0; utilizando como referência o Grupo Controle (GC e observando o comportamento da função sistodiastólica ventricular esquerda expressa por meio do Índice de Performance Miocárdica (IPM. MÉTODOS: Foram realizados ecocardiogramas transtorácicos no período de janeiro de 2006 a janeiro de 2008, para a avaliação prospectiva de 47 pacientes, subdivididos em GC (36,2%, TX0 (38,3% e TX1 (25,5%, comparando-se o IPM entre eles. Para a análise dos dados foram realizados os testes exato de Fisher e o não paramétrico de Kruskal-Wallis, ambos com nível de significância de 5%. RESULTADOS: Os grupos não diferiram em relação a idade, peso, altura e superfície corpórea. Quando comparado ao GC, TX0 e TX1 apresentaram alteração da função sistodiastólica ventricular esquerda, expressa como aumento do IPM, que foi mais intenso no TX1 [0,38 (0,29 - 0,44 X 0,47 (0,43 - 0,56 X 0,58 (0,52 - 0,74 p < 0,001]. CONCLUSÃO: O ecocardiograma mostrou-se como exame de boa acurácia na detecção das alterações da função sistodiastólica do coração transplantado; entretanto, não foi confiável como método substituto da BEM para o diagnóstico seguro de RC.

    Full Text Available O presente artigo é resultado de uma pesquisa etnográfica com doentes hepáticos graves crônicos e transplantados do Serviço de Transplante Hepático do HC-UFPR. A pesquisa foi realizada com o emprego do método etnográfico, tendo como base a hipótese de que o diagnóstico de doença grave e crônica quando anunciado pela equipe médica representa um evento traumático para o doente. A presença do trauma produz uma ruptura na temporalidade biográfica do indivíduo. Passado e presente se desconectam e o futuro desaparece como projeto, dando seu lugar para a iminência da morte. A construção de uma narrativa sobre a experiência vivida aparece como estratégia possível para resolver a ausência de significado da experiência. Sua construção passa por vicissitudesinscritas na dificuldade que o indivíduo possui de objetivar o evento traumático. A presença da doença enquanto conjunto de sintomas que afetam a imagem corporal e a identidade do doente, não se resolve somente com o transplante, o que por sua vez também exige significação. Os elementosteóricos aqui considerados para a análise dos dadossão fornecidos por Strauss(1999, Goffman (1988 e 2008, Schutz (1970 e 2003, Kleinman (1988, Rabelo ( 1999, LeBreton (2006 e Sarti (2010.

    Full Text Available Medidas objetivas de avaliação de qualidade de vida vêm aumentando em importância como adjuvante da análise de intervenções terapêuticas. Com o objetivo de analisar a qualidade de vida em pacientes renais crônicos transplantados, com enxerto funcionante ou que retornaram para tratamento dialítico, foi utilizada a versão em português do World Health Organization Quality of Life (WHOQOL-Bref. Foram estudados 132 pacientes, submetidos ao transplante renal, divididos em dois grupos: grupo I, 100 pacientes com enxerto funcionante e grupo II, 32 pacientes que perderam a função do enxerto e retornaram para tratamento dialítico. A avaliação dos diferentes itens do WHOQOL-Bref mostrou uma melhor qualidade de vida para os pacientes com enxerto funcionante nos domínios físico e psicológico, mas não nos domínios de relações sociais e de meio ambiente, valores estes confirmados pela avaliação das questões gerais. Esse instrumento de avaliação mostrou-se eficaz, pois privilegia a opinião dos pacientes, permitindo uma abordagem multidisciplinar do problema.

Resultados: houve uma predominância do sexo masculino em relação ao feminino. Predomínio da faixa etária de 29 a 39 anos, com 33% dos casos. Conforme identificado, o tipo de doação renal que mais se destacou foi de doador falecido, que representou 97,2% dos transplantes realizados, enquanto com doador vivo foi apenas 2,8%. Em relação ao tempo que os pacientes permaneceram em tratamento dialítico antes do transplante, observou-se uma predominância deste tratamento substitutivo por mais de 24 meses com 62,3% dos casos. Conclusão: o transplante renal não representa uma cura, e sim uma outra forma de tratamento substitutivo, é uma opção que abre possibilidades para uma vida bem próxima da normalidade.

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

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 A case of invasive aspergillosis caused by Aspergillus niger in a lung transplant recipient is described. The patient presented hyperglycemia starting postoperatively, with other complications such as cytomegalovirus infection. The associated predisposing factors and other implications are discussed. Aspergillus niger seems to be a fungal species of low virulence that requires the presence of a severely immunosuppressed host to cause invasive disease.Descreve-se um caso de aspergilose invasiva causada por Aspergillus niger em um paciente transplantado de pulmão com quadros hiperglicêmicos desde o pós-operatório e outras complicações como infecção por citomegalovírus. Os fatores predisponentes associados e outras implicações são discutidos. Aspergillus niger parece ser uma espécie fúngica de baixa virulência, necessitando a presença de um hospedeiro gravemente imunodeprimido para causar doença invasiva.

    Soulier, Jean

    2011-01-01

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

Las concentraciones de ferritina sérica son constantemente monitoreadas en estos pacientes para detectar rápidamente la presencia de sobrecarga de hierro. El objetivo del estudio fue determinar si hubo correlación entre los valores de ferritina sérica y el número de unidades de transfusión de concentrado eritrocitario suministradas a los pacientes con ACS y βT mayor o intermedia durante un año. Se realizó un estudio prospectivo de 39 pacientes,22 fueron diagnosticados de ACS y 17 con βT, en edades comprendidas entre los 4 y 82 años. Estos pacientes fueron tratados en el "Instituto Hematológico de Occidente -Banco de Sangre del Estado Zulia y el Hospital Universitario de Maracaibo Venezuela”. Ferritina sérica se determinó por el método de quimioluminiscencia.

  8. 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

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

Comparing patients with healthy controls, the investigation of the subpopulations revealed higher medium-fluorescent reticulocyte (12.69 ± 6.69% vs. 5.88 ± 3.59%, respectively p<0.01 and high-fluorescent reticulocyte (1.45 [0.38-3.10] vs. 0.40 [0.00-0.90], p<0

  14. Avaliação hormonal indireta e estudo da preservação folicular em tecido ovariano autólogo transplantado para região inguinal em ratos

    Full Text Available OBJETIVO: O transplante autólogo de tecido ovariano tem sido objeto de estudo de diversos pesquisadores pela perspectiva de manter a funcionalidade deste órgão, mesmo não localizado em seu sítio habitual, sendo daí removido, a fim de minimizar os efeitos causados, por exemplo, pela radioterapia. Este trabalho visa a analisar a efetividade da técnica de autotransplante subcutâneo de tecido ovariano bisseccionado em região inguinal de ratas albinas, próximo aos vasos femorais, através do estudo indireto da produção hormonal, feita pela avaliação da citologia de esfregaços vaginais e do estudo direto da viabilidade tecidual, realizado por meio da análise histológica. MÉTODOS: Analisaram-se 30 ratas, que sofreram ooforectomia bilateral, sendo 15 delas destinadas ao controle e 15 submetidas ao transplante ovariano. Decorridos 28 dias, recuperaram-se e avaliaram-se os enxertos. As análises da citologia dos esfregaços vaginais efetuaram-se no momento 0, ou seja, pré-transplante, e no momento 1, pós-transplante, para os animais de ambos os grupos e a avaliação histológica realizou-se no momento 0 para os dois grupos e no momento 1 para os animais transplantados. RESULTADOS: Os resultados do experimento demonstraram a viabilidade e funcionalidade dos enxertos em 100% das lâminas analisadas, isso verificado através da obtenção de esfregaços em fase de estro para todas as ratas do grupo experimento e da presença de folículos em vários estágios de desenvolvimento, observados nos enxertos recuperados, indicando diretamente a viabilidade do tecido ovariano. CONCLUSÃO: o transplante de tecido ovariano é uma alternativa viável, nas condições do experimento, para a preservação hormonal e folicular, em ratas.

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

    Full Text Available Introdução: Sintomas de desesperança, ideação suicida e depressão influenciam na qualidade e expectativa de vida de doentes renais crônicos. Objetivo: Avaliar se existe diferença nos sintomas de desesperança, ideação suicida e depressão entre pacientes renais crônicos em hemodiálise ou transplantados. Analisamos também se variáveis sociodemográficas como atividade laboral, ter dependentes, sexo e estado civil interferem nesses sintomas. Métodos: Estudo comparativo, de corte transversal, em que 50 pacientes em hemodiálise crônica e 50 transplantados renais, clinicamente estáveis, sem psicopatologias, pareados por sexo e idade, foram selecionados aleatoriamente. Instrumentos -Beck Hopelessness Scale (BHS, Beck Scale for Suicide Ideation (BSI e Beck Depression Inventory (BDI. Resultados: BHS: 2% de cada grupo tiveram escore > 8 (p = 1,00.

Não houve relação entre as variáveis testadas e os sintomas de desesperança e ideação suicida. Não exercer atividade laboral implicou mais sintomas depressivos (escore médio BDI: 10,5 vs. 7,3, p = 0,027. Transplantados de doadores falecidos apresentaram mais sintomas depressivos comparados aos receptores de doadores vivos (escore médio BDI: 11,0 vs. 6,7, p = 0,042. Conclusão: Não houve diferença na intensidade dos sintomas de desesperança, ideação suicida e depressão entre pacientes estáveis em hemodiálise e transplantados. Não exercer atividade laboral e receber transplante de doador falecido levou a mais sintomas depressivos. A prevalência de ideação suicida e sintomas depressivos, nas duas modalidades, merece atenção e indica a necessidade de monitorização e cuidados nesses pacientes.

    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.

    2009-04-01

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

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

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

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

    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.

    La anemia de Fanconi es una falla clásica de la médula ósea, la cual tiene una incidencia de menos de 1 en 100,000 nacidos vivos. Hasta ahora, las pacientes femeninas normalmente no alcanzaban la edad reproductiva y mucho menos lograban el embarazo. Una revisión actual de la literatura identifica solamente 19 pacientes que han logrado el embarazo. Presentamos el caso de una paciente de 16 años portadora de anemia de Fanconi, la cual presenta un embarazo de 30 semanas complicado por un cuadro ...

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

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

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

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

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

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

    Nelly Zavaleta

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

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

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

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

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

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

MÉTODOS: Avaliamos trinta transplantados renais do sexo masculino com função renal estável, idade média de 41,3 anos. RESULTADOS: A detecção da carga aterosclerótica nesta população foi significativa quando utilizada a técnica da reatividade braquial (86,7%, menos freqüente baseando-se na presença de placa carotídea (33,3% ou no escore de cálcio coronariano (20%. Placa carotídea foi considerada quando a espessura era superior a 12 mm. O escore de cálcio coronariano foi anormal quando acima de oitenta pela escala de Agatston, sendo observado em um percentual baixo (21,7% dos pacientes, possivelmente porque a tomografia pode não ser o método ideal para detectar aterosclerose em doentes renais, por não distinguir calcificações intimais da camada média. O controle clínico adequado, a baixa faixa etária e fatores relacionados ao tempo de diálise pré-transplante ou ao efeito antiinflamatório das drogas pós-transplante podem retardar o aparecimento das calcificações.

    2015-01-01

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

    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

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

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

    Full Text Available A anemia ferropriva, talassemia menor e anemia de doença crônica são as anemias microcíticas e hipocrômicas mais comuns em nosso meio. O diagnóstico diferencial das referidas anemias é de grande importância clínica; contudo, muitas vezes é complexo em virtude de concomitância de doenças, além de demandar tempo e apresentar custos significativos. Com o propósito de conferir maior simplicidade e eficiência ao diagnóstico diferencial destas anemias, o uso de índices derivados de modernos contadores automáticos tem sido sugerido. Entre estes, pode ser citado o índice de anisocitose eritrocitária (RDW, que indica o grau de variabilidade do tamanho das hemácias. Neste estudo, o poder de discriminação deste índice quanto ao tipo de anemia microcítica e hipocrômica foi avaliado em um grupo de 159 pacientes sabidamente portadores de um quadro de anemia causado por deficiência de ferro, beta talassemia menor ou uma anemia de doença crônica. Não foi observada diferença significativa para o RDW entre os três grupos de anemias microcíticas, indicando não ser este índice uma ferramenta útil para a diferenciação entre anemia ferropriva, beta talassemia menor e anemia de doença crônica.Iron deficiency anemia, the thalassemia trait and chronic disease anemia are the most common microcytic and hypochromic anemias in the Brazilian population. Differential diagnosis of these anemias is of great clinical importance however, frequently, it is complex due to coexistence of diseases, as well as being time consuming and expensive. In order to simplify and increase efficiently of checking the differential diagnoses of these anemias, the use of indexes derived from modern blood cell counters has been suggested. Among them, is the index called red blood cell distribution width which indicates the variability in red blood cell size.

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

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

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

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

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

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

    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.

    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.

    Science.gov (United States)

    Ohga, Shouichi

    2016-01-01

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

  10. Diagnosis of Fanconi Anemia by Diepoxybutane Analysis

    2015-01-01

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

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

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

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

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

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

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

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

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

  7. Fanconi anemia proteins in telomere maintenance.

    2016-07-01

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

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

    2017-01-01

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

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

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

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

MÉTODOS: Participaram do estudo 357 crianças, de quatro a 24 meses, de três serviços de atenção básica à saúde da região sul da cidade. As variáveis foram separadas em categorias relacionadas à mãe e à criança. A dosagem de hemoglobina foi realizada por punção digital, com ponto de corte de 11g/dL para o diagnóstico de anemia. O teste t de Student foi aplicado para comparar as médias de hemoglobina de dois grupos independentes; a ANOVA, para três ou mais grupos; e o teste de Mann-Whitney para comparar a velocidade de crescimento e o grupo etário. RESULTADOS: A prevalência de hemoglobina abaixo de 11g/dL foi de 60%. Entre as variáveis maternas, não se constatou associação com a ocorrência de anemia. Houve associação entre anemia, gênero da criança e velocidade de ganho de peso. Quanto à alimentação, não foi encontrada associação entre tempo de aleitamento materno e anemia, mas houve associação com a ingestão quantitativa e qualitativamente pobre em ferro. CONCLUSÕES: A alta prevalência de anemia relacionou-se ao gênero masculino, no qual a velocidade de crescimento em menores de seis meses e naqueles com 18 a 24 meses foi maior, além de se associar à baixa ingestão de ferro na dieta.OBJECTIVE: To analyze mother and child factors associated with the occurrence of anemia in children assisted at primary health care centers in São Paulo city, Brazil.

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

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

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

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

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

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

  9. The cutting edge of aplastic anemia treatment.

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

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

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

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

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

    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.

    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.

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

    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.

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.

  12. Hepatitis Associated Aplastic Anemia: A review

    Science.gov (United States)

    2011-01-01

    Hepatitis-associated aplastic anemia (HAAA) is an uncommon but distinct variant of aplastic anemia in which pancytopenia appears two to three months after an acute attack of hepatitis. HAAA occurs most frequently in young male children and is lethal if leave untreated. The etiology of this syndrome is proposed to be attributed to various hepatitis and non hepatitis viruses. Several hepatitis viruses such as HAV, HBV, HCV, HDV, HEV and HGV have been associated with this set of symptoms. Viruses other than the hepatitis viruses such as parvovirus B19, Cytomegalovirus, Epstein bar virus, Transfusion Transmitted virus (TTV) and non-A-E hepatitis virus (unknown viruses) has also been documented to develop the syndrome. Considerable evidences including the clinical features, severe imbalance of the T cell immune system and effective response to immunosuppressive therapy strongly present HAAA as an immune mediated mechanism. However, no association of HAAA has been found with blood transfusions, drugs and toxins. Besides hepatitis and non hepatitis viruses and immunopathogenesis phenomenon as causative agents of the disorder, telomerase mutation, a genetic factor has also been predisposed for the development of aplastic anemia. Diagnosis includes clinical manifestations, blood profiling, viral serological markers testing, immune functioning and bone marrow hypocellularity examination. Patients presenting the features of HAAA have been mostly treated with bone marrow or hematopoietic cell transplantation from HLA matched donor, and if not available then by immunosuppressive therapy. New therapeutic approaches involve the administration of steroids especially the glucocorticoids to augment the immunosuppressive therapy response. Pancytopenia following an episode of acute hepatitis response better to hematopoietic cell transplantation than immunosuppressive therapy. PMID:21352606

    ABSTRACT. Anemia has long been known to be a complication of end-stage renal disease (ESRD), and it has been linked to cardiovascular morbidity and mortality. Although kidney transplant recipients (KTR) are prone to experiencing cardiovascular outcomes, little is known about the epidemiology of anemia in this population. With few exceptions, studies to date have not fully evaluated the associations between posttransplant anemia (PTA) and medications commonly used in KTR, particularly immunosuppressant drugs, angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB). The authors aimed to specifically investigate possible associations between these drugs and PTA. Detailed medical information was retrospectively collected on 374 consecutive KTR from our transplant clinic. Univariate/multivariate linear regression models were used to test for associations between hematocrit (HCT) and other covariates, and logistic regression models were used to detect independent predictors of PTA, defined as HCT <33%. The mean time since transplantation was 7.7 yr, and mean creatinine was 2.2 mg/dl. The prevalence of PTA was 28.6%. Ten percent of all patients were on erythropoietin therapy, but only 41.6% of patients whose HCT was <30 received this treatment. From multivariate analyses, the authors found that female gender and lower renal function were associated with lower HCT (both P < 0.001). Patients on ACEI had significantly lower HCT (P = 0.005) compared with patients without such treatment. In addition, a significant curvilinear dose-response relationship was found between ACEI dose and HCT. Among the immunosuppressant drugs, mycophenolate mofetil (P = 0.05) and tacrolimus (P = 0.02) were associated with a lower HCT. The authors conclude that PTA is prevalent and undertreated in KTR. Several medications that are possibly modifiable correlates of PTR deserve further study.

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

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

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

    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

    Fanconi anemia (FA) is a recessive human cancer prone syndrome featuring bone marrow failure, developmental abnormalities and hypersensitivity to DNA crosslinking agents exposure. 11 among 12 FA gene have been isolated. The biochemical functions of the FANC proteins remain poorly understood. Anyhow, to cope with DNA crosslinks a cell needs a functional FANC pathway. Moreover, the FANC proteins appear to be involved in cell protection against oxidative damage and in the control of TNF-alpha activity. In this review, we describe the current understanding of the FANC pathway and we present how it may be integrated in the complex networks of proteins involved in maintaining the cellular homeostasis.

    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.

    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 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.

METHODS: Children of both genders, from 6 to 72 months, registered in public day-care centers in the city of Guaxupé, were studied. Nutritional evaluation was conducted using the Z-score for height-to-age and weight-to-height relationships. Hemoglobin dosage, serum iron, total iron binding capacity and the transferrin saturation index were used for diagnosis of anemia. RESULTS: Z score < - 2 was observed in 3.3% of the children for the height-to-age relationship and of 0.4% for the weight-to-height relationship. Prevalence of total iron deficiency anemia was of 16.1%. In the age span from 6 to 36 months it was of 44.6%. The entire sample showed 45% with low serum iron, 37.9% with high total iron binding capacity and 43.1% with a low transferrin saturation index. CONCLUSION: Malnutrition was not considered to be a problem due to its low prevalence; however, an important prevalence of iron deficiency was observed. Iron deficiency anemia is more prevalent in children between 6 and 36 months confirming that this age span is more vulnerable. No association between iron deficiency anemia and the Z score of the studied anthropometry relationships was found.

Classification of AIHA is based on the optimal auto-RBC antibody reactivity temperatures and includes warm, cold-reactive, mixed AIHA, and drug-induced AIHA subtypes. AIHA is a rare disease, and recommendations for transfusion are based mainly on results from retrospective data and relatively small cohort studies, including heterogeneous patient samples or single case reports. In this article, we will review the challenges and solutions to safely transfuse AIHA patients. We will reflect on the indication for transfusion in AIHA and the difficulty in the accomplishment of immunohematological procedures for the selection of the safest and most compatible RBC units.

    Fanconi anemia (FA) is a rare autosomal recessive disorder clinically characterized by developmental abnormalities, progressive bone marrow failure (BMF) and profound cancer predisposition. Approximately 65% of all affected individuals have mutation in the FANCA (Fanconi anemia complementation group A) gene. The mutation spectrum of the FANCA gene is highly heterogeneous. FA-A is usually associated with private FANCA mutations in individual families. We describe 3 unrelated patients with FA with a similar clinical presentation: BMF, renal anomalies and café-au-lait pigmentation without major skeletal abnormality. The molecular analysis of the FANCA gene using the FA MLPA kit P031-A2/P032 FANCA, showed homozygous deletion of exon 3 in all 3 patients. Molecular analysis of the flanking regions of exon 3 precisely defined unique deletion of 2,040 bp and duplication of C (1788_3828dupC). These are the first 3 patients homozygous for deletion of FANCA exon 3 described to date. Although not related, the patients originated from the same Gypsy-like ethnic population. We conclude that c.190-256_283 + 1680del2040 dupC mutation in the FANCA gene is a founder mutation in Macedonian FA patients of Gypsy-like ethnic origin. Our finding has very strong implications for these patients in formulating diagnostic and carrier-screening strategy for BMF and FA and to enable comprehensive genetic counseling. © 2013 S.

    Extracellular histones have been shown to play an important pathogenic role in many diseases, primarily through their cytotoxicity toward nucleated cells and their ability to promote platelet activation with resultant thrombosis and thrombocytopenia. In contrast, little is known about the effect of extracellular histones on erythrocyte function. We demonstrate in this study that histones promote erythrocyte aggregation, sedimentation, and using a novel in vitro shear stress model, we show that histones induce erythrocyte fragility and lysis in a concentration-dependent manner. Furthermore, histones impair erythrocyte deformability based on reduced passage of erythrocytes through an artificial spleen. These in vitro results were mirrored in vivo with the injection of histones inducing anemia within minutes of administration, with a concomitant increase in splenic hemoglobin content. Thrombocytopenia and leukopenia were also observed. These findings suggest that histones binding to erythrocytes may contribute to the elevated erythrocyte sedimentation rates observed in inflammatory conditions. Furthermore, histone-induced increases in red blood cell lysis and splenic clearance may be a significant factor in the unexplained anemias seen in critically ill patients. © 2017 by The American Society of Hematology.

  14. Microfluidic approach of Sickled Cell Anemia

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

    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

    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.

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

    The Toba/Qom of Namqom are an indigenous community native to the Gran Chaco region of northern Argentina. Historically seminomadic foragers, the diet of peri-urban community members has rapidly changed from high-protein, high-fiber to hypercaloric, processed. This study aims to understand the impact of this nutritional transition on aspects of women's health by exploring the relationship between prevalence of anemia and current diet composition, place of birth, and reproductive history. We measured the capillary hemoglobin (Hb) levels of 153 adult women. Each participant was also given two interviews characterizing reproductive history and a 24-hour food recall. The average Hb level was 12.6 g/dL (range 5.8-15.7 g/dL). In our sample, 28% of participants were anemic and 31% were borderline anemic. Iron and vitamin C consumption were negatively associated with Hb levels. Body mass index was marginally associated with Hb levels. Being born in a peri-urban setting, a proxy for early Westernized diet was associated with higher risk of anemia, suggesting developmental experience may play a role. Pregnant and lactating women had lower Hb levels than menstruating and menopausal women. Age, height, parity, and age at first pregnancy were not found to be statistically significant predictors of anemia. Iron deficiency represents a serious health concern for women, particularly pregnant ones. Our results suggest that both past and current nutritional ecology variables may be associated with the risk of anemia. These findings inform public health interventions, since reproductive history may be more difficult to modify than current diet. © 2017 Wiley Periodicals, Inc.

    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.

    Anemia is a common phenomenon in women during the reproductive years. In pregnancy, it is associated with an increased incidence of maternal-fetal morbidity and mortality. The approach to the investigation of anemic women suspected of having hemolytic anemia of either congenital or acquired etiology is the subject of this article. Various conditions in the pregnant women can have hematologic consequences for the newborn infant; these conditions include sensitization to fetal blood cells, infections, drug ingestion and the possession of genes for hereditary hemolytic disorders, which may be transmitted to the fetus. Because several forms of hemolytic anemias are hereditary or are caused by an altered gene, genetic consultation is important.

    Pernicious anemia is currently the most common cause of vitamin B12 deficiency in Western countries. The histological lesion upon which this condition is based is autoimmune chronic atrophic gastritis. The destruction of parietal cells causes a deficiency in intrinsic factor, an essential protein for vitamin B12 absorption in the terminal ileum. Advances in the last two decades have reopened the debate on a disease that seemed to have been forgotten due to its apparent simplicity. The new role of H. pylori, the value of parietal cell antibodies and intrinsic factor antibodies, the true usefulness of serum vitamin B12 levels, the risk of adenocarcinoma and gastric carcinoids and oral vitamin B12 treatment are just some of the current issues analyzed in depth in this review.

    Survival in severe aplastic anemia (SAA) has markedly improved in the past 4 decades because of advances in hematopoietic stem cell transplantation, immunosuppressive biologics and drugs, and supportive care. However, management of SAA patients remains challenging, both acutely in addressing the immediate consequences of pancytopenia and in the long term because of the disease's natural history and the consequences of therapy. Recent insights into pathophysiology have practical implications. We review key aspects of differential diagnosis, considerations in the choice of first- and second-line therapies, and the management of patients after immunosuppression, based on both a critical review of the recent literature and our large personal and research protocol experience of bone marrow failure in the Hematology Branch of the National Heart, Lung, and Blood Institute.

    Both the peripheral lymphocytes from 4 patients affected with the inherited disease Fanconi's anemia (FA), and tissue-culture fibroblasts from skin biopsies from 33 patients similarly affected were found to be about twice as sensitive to the induction of chromatid-type chromosomal aberrations by X-rays administered in the G 2 phase of the cell cycle as cells from normal controls. Using tritiated thymidine labelling of peripheral lymphocytes and of cultured fibroblasts, it was determined that 3 affected patients and 3 normal controls all had similar percent labeled mitoses (PLM) curves, so the increased induced aberration yields seen in the FA cells do not appear to be simply a consequence of a longer than normal G 2 phase of the cell cycle.

    2012-01-01

    The Fanconi anemia (FA) pathway maintains genome stability through co-ordination of DNA repair of interstrand crosslinks (ICLs). Disruption of the FA pathway yields hypersensitivity to interstrand crosslinking agents, bone marrow failure and cancer predisposition. Early steps in DNA damage dependent activation of the pathway are governed by monoubiquitylation of FANCD2 and FANCI by the intrinsic FA E3 ubiquitin ligase, FANCL. Downstream FA pathway components and associated factors such as FAN1 and SLX4 exhibit ubiquitin-binding motifs that are important for their DNA repair function, underscoring the importance of ubiquitylation in FA pathway mediated repair. Importantly, ubiquitylation provides the foundations for cross-talk between repair pathways, which in concert with the FA pathway, resolve interstrand crosslink damage and maintain genomic stability.

    Fanconi anemia (FA) is a rare inherited syndrome with diverse clinical symptoms including developmental defects, short stature, bone marrow failure, and a high risk of malignancies. Fifteen genetic subtypes have been distinguished so far. The mode of inheritance for all subtypes is autosomal recessive, except for FA-B, which is X-linked. Cells derived from FA patients are—by definition—hypersensitive to DNA cross-linking agents, such as mitomycin C, diepoxybutane, or cisplatinum, which becomes manifest as excessive growth inhibition, cell cycle arrest, and chromosomal breakage upon cellular exposure to these drugs. Here we provide a detailed laboratory protocol for the accurate assessment of the FA diagnosis as based on mitomycin C-induced chromosomal breakage analysis in whole-blood cultures. The method also enables a quantitative estimate of the degree of mosaicism in the lymphocyte compartment of the patient. PMID:22693659

    2014-01-01

    Tumor necrosis factor-alpha (TNF-α) is a major pro-inflammatory cytokine involved in systemic inflammation and the acute phase reaction. Dysregulation of TNF production has been implicated in a variety of human diseases including Fanconi anemia (FA). FA is a genomic instability syndrome characterized by progressive bone marrow failure and cancer susceptibility. The patients with FA are often found overproducing TNF-α, which may directly affect hematopoietic stem cell (HSC) function by impairing HSC survival, homing and proliferation, or indirectly change the bone marrow microenvironment critical for HSC homeostasis and function, therefore contributing to disease progression in FA. In this brief review, we discuss the link between TNF-α signaling and FA pathway with emphasis on the implication of inflammation in the pathophysiology and abnormal hematopoiesis in FA. © 2013.

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

As cadeias leves no plasma e na urina estavam elevadas, sobretudo a fração kappa e uma biópsia renal estudada por imunofluorescência e microscopia eletrônica confirmou o diagnóstico de Doença de Depósito das Cadeias Leves. A nefropatia de cadeia leve ocorre pela superprodução de cadeia leve de imunoglobulina produzida por linfócitos B com deposição nas membranas tubulares e no glomérulo.The authors present a case of a 65-year-old female patient, with chronic anemia associated with glomerulopathy manifested as proteinuria, cylindruria and renal failure. There were high serum and urinary levels of light chains and the diagnosis was performed by renal biopsy, examined using immunofluorescence and by electron microscopy that showed light chain paraproteins. Nephropathy of light-chain deposition disease occurs due to an over-production of light chains from immunoglobulins produced by B lymphocytes with a deposit in tubular and glomerular membranes.

    Full Text Available El hematocrito (Hto, como indicador de anemia en individuos y poblaciones, experimenta variaciones en función de factores mesológicos y genéticos. La anemia constituye una enfermedad endémica cuya prevalencia en Argentina, en distintos grupos de edad y de riesgo y particularmente en escolares, es insuficientemente conocida. El objetivo de este trabajo fue conocer la variación del Hto en escolares de la ciudad de San Salvador de Jujuy localizada a 1200 m.s.n.m., evaluar la prevalencia de anemia y relacionar estas variaciones con las características socioeconómicas de la población. Los datos del Hto procedieron de 17.580 escolares de escuelas públicas y privadas. Para su análisis se agruparon por edad, sexo y nivel socio-económico. Se consideró como anémicos a los niños cuyo Hto se encontró por debajo de: a el valor mínimo aceptado para el nivel de 1200 m; b -2 desviaciones estándar. Para el análisis se empleó: ANOVA, c2 y coeficiente de correlación. Los valores promedio del Hto, independientemente de la edad, sexo y nivel socioeconómico, coinciden con los de la referencia ajustados para la altura. Se observaron: a diferencias intersexuales estadísticamente significativas, presentando los varones, valores superiores a los de las mujeres; b una tendencia al aumento del Hto con relación al incremento del nivel socioeconómico. La prevalencia de anemia, independientemente del criterio utilizado, fue baja en ambos sexos, grupos de edad y en todos los niveles socioeconómicos. Los valores del hematocrito: a son representativos de una población escolar situada a una altitud moderada; b pese a la tendencia a disminuir en el nivel socioeconómico bajo no superan, en la mayoría de los casos, el nivel crítico de anemia; c no indican presencia de desnutrición en la población escolar examinada.The hematocrit (Ht, as an indicator of anemia in individuals and populations, shows variations in relation to mesologic and genetic factors

    Full Text Available BACKGROUND: Infections after liver transplantations are the most important cause of morbi-mortality. In this study, we assessed the main characteristics of these infections in a southern Brazilian university hospital. METHODS: We conducted a retrospective cohort with 55 patients who underwent orthotopic liver transplantation between 1996 and 2000 in the "Hospital de Clínicas de Porto Alegre", Porto Alegre, RS, Brazil, to characterize the infections that occurred in the group. RESULTS: One or more infections (average 2.10 were diagnosed in 47 patients, especially during the first month after transplantation. The most common were bacteremia, intra-abdominal infections and pneumonia, predominantly with bacteria, especially Staphylococcus sp (and particularly S. aureus and E. coli. The mortality rate attributed to infections was high: 17 cases of all deaths (total 27 deaths. Significant risk factors for infections included reoperation, diabetes, biliary stenosis and higher Child-Pugh scores. CONCLUSION: Infections remain a severe threat in liver transplant patients, and special efforts should be made to prevent and manage them correctly.RACIONAL: Infecções são a causa principal de morbimortalidade em pacientes submetidos a transplantes hepáticos. OBJETIVO: Avaliar as principais características destas infecções em pacientes de um hospital universitário do sul do Brasil. MÉTODO: Uma coorte retrospectiva foi conduzida com os 55 pacientes transplantados hepáticos adultos cuja cirurgia foi realizada entre 1996 e 2000 no Hospital de Clínicas de Porto Alegre, RS, todos aos eventos infecciosos que ocorreram nesta população foram registrados. RESULTADOS: Uma ou mais infecções (média 2,1 episódios foram diagnosticadas em 47 pacientes, o período de maior ocorrência destas foi o primeiro mês após a cirurgia. As infecções mais comuns foram: bacteremias, infecções intra-abdominais e pneumonias, a etiologia mais freqüente foi bacteriana
