    Tanto el virus de la enfermedad de Marek (MDV) y virus de la anemia infecciosa aviar (CIAV) son patógenos inmunosupresores que causan el síndrome de mortalidad temprana y bajas en la producción cuando se da una coinfección. Aunque la industria avícola colombiana ha aumentado casi al doble en la última década, no hay información sobre algunos agentes infecciosos que circulan en el país. Es poco probable que ocurran casos clínicos de MVD debido a los programas de vacunación generalizada con MVD...

    Full Text Available ResumenLa bronquitis infecciosa aviar (BIA es una enfermedad que ocasiona unimpacto socio-económico severo en la industria avícola mundial. Es unaenfermedad respiratoria aguda, altamente contagiosa, caracterizadaprimariamente por signos respiratorios en los pollos en crecimiento. En las ponedoras, la sintomatología respiratoria es menor pero provoca una disminución marcada en la producción y calidad del huevo. El agente etiológico de esta enfermedad es el virus de la bronquitis infecciosa aviar, un Coronavirus del grupo 3 de la familia Coronaviridae, orden Nidovirales. El virus se replica en los tejidos del tracto respiratorio y en muchos tejidos a lo largo del tracto alimentario. Este virus puede infectar otras especies de aves además de los pollos. Los signos clínicos característicos son tos, estornudos, estertores traqueales, ojos acuosos, letargo y en los pollos, especialmente los jóvenes, se presentan descargas nasales. Estos signos son indicativos pero no tienen por sí solo valor diagnóstico y la confirmación requiere el aislamiento o la demostración directa de la presencia del virus aunque la serología puede ser útil en algunas circunstancias. El diagnóstico de laboratorio requiere el aislamiento viral y su identificación. Se emplean las técnicas de reacción en cadena de la polimerasa (RT-PCR, inhibición de la hemaglutinación (HI y ensayos inmunoenzimáticos (ELISA, así como la microscopía electrónica, anticuerpos monoclonales, virus neutralización (VN, inmunohistoquímica,ensayos de inmunofluorescencia y de inmunización desafío en pollos. Son ampliamente usadas vacunas vivas e inactivadas en el control de laenfermedad.SummaryAvian infectious bronchitis (BIA is a disease that provokes a severe socioeconomic impact in poultry world industry.

    Full Text Available Objetivo. Determinar el nivel de asociación serológica entre los herpesvirus equinos tipos 1 y 4 (HVE-1 y HVE-4 causantes de la rinoneumonitis equina y el virus de la anemia infecciosa equina (VAIE en caballos de trabajo provenientes de 5 municipios del Meta. Materiales y métodos. Se realizó una encuesta serológica transversal en 68 equinos provenientes de los municipios de San Martín, Guamal, Restrepo, Cumaral y Paratebueno. Para la evaluación de los anticuerpos contra los HVE-1 y HVE-4, se utilizó un ELISA indirecto para detectar la presencia de anticuerpos dirigidos contra la glicoproteína G del HVE-1 y HVE-4 (Svanovir ™ EHV1/EHV4-Ab ELISA; para el diagnóstico de anticuerpos contra el VAIE se utilizó la prueba de inmunodifusión en agar de gel de Coggins. Resultados. No se encontraron reactores al HVE-1; sin embargo, el porcentaje de seropositividad fue de 94.12% (64/68 y 13.2%(9/68 para HVE-4 y VAIE respectivamente. El porcentaje de animales coinfectados HVE-4 y AIE fue 13.23% (9/68. Cuando se discriminaron los resultados por Municipio se encontró un 27.9% (19/68 de reactividad en el municipio de Restrepo, 26.5% (18/68 en Cumaral, 14.7% (10/68 en Paratebueno, 14.7% (10/68 en Guamal, y 10.3% (7/68 en San Martin. El porcentaje de reactores por municipio al VAIE fue Cumaral 5.88% (4/68, Restrepo 4.4% (3/68, Guamal 1.47%(1/68 y San Martín 1.47% (1/68. Conclusión. El alto porcentaje de coinfección entre HVE-4 y VAIE sugiere un efecto importante en la interacción, pues el efecto inmunosupresor del VAIE podría facilitar la reactivación del estado latente del HVE-4.

    Full Text Available En el estudio se evaluó la prevalecía de anemia infecciosa equina (AIE en los caballos de tracción en el municipio de Florencia, buscando relación por sexo, edad, condición corporal y distribución por comunas. Para ello se recolectaron 128 muestras de sangre de equinos (103 machos y 25 hembras que asistieron a 4 brigadas de salud animal realizadas por el semillero de investigación en equinos “SIEQUUS”, de la Universidad de la Amazonia, durante el periodo comprendido entre mayo de 2014 y diciembre de 2015. Las muestras fueron analizadas en laboratorio con la prueba de inmunodifusión en agar gel. Se realizó análisis estadístico descriptivo y una prueba Chí cuadrado (P10 fue del 14.29 %, y en los animales entre 5 y 10 años fue considerablemente mayor, el 33.33 %. Las condiciones ambientales y socioeconómicas facilitan la transmisión del virus entre los caballos del mismo gremio y con cualquier sistema de manejo y producción equina de la zona, lo que generaría pérdidas económicas y de semovientes de importancia para el sector equino.

Son las células más pequeñas de la sangre aviar (8 x 5 mµ, y a menudo existe dificultad para diferenciarlos de los pequeños linfocitos. No hay megacariocitos en la médula ósea de las aves por lo que se originan de precursores nucleados. En el embrión aparecen en el día 2 de incubación a partir del saco vitelino y en la medula ósea a partir del día 12. Se sabe muy poco sobre su sitio de origen en la médula ósea pero al parecer sería intrasinusoidal. Sus funciones hemostáticas en gran parte son análogas a las de las plaquetas de mamíferos. Además de estas funciones, los TBCs son activos fagocitos dentro de la circulación. Por este motivo se los ha postulado como células activas en la defensa inespecífica, aunque este aspecto resulta aún muy controvertido. El recuento absoluto de TBCs rara vez se realiza en la clínica rutinaria, por lo que es muy poco lo que se sabe de su relevancia clínica así como de aspectos relacionados con su cinética.

    Anemias continue to present a challenge to the health care profession. Anemia is defined as a reduction in one or more of the RBC indices. Patients presenting with a mild form of anemia may be asymptomatic; however, in more serious cases the anemia can become life threatening. In many cases the clinical presentation also reflects the underlying cause. Anemia may be attributed to various causes, whereas autoimmune RBC destruction may be attributed to intrinsic and extrinsic factors. Laboratory tests are essential in facilitating early detection and differentiation of anemia.

    Full Text Available The objective of this study was to determine the occurrence and risk factors associated with the identification of equine infectious anemia (EIA in traction equines in the city of São Luiz - MA. We collected blood samples from 154 equines seized on public roads by the Sector of Animal Traction Seizure of the Municipal Urban Development and Housing Department between April and August of 2011. We analyzed the medical records to determine the individual risk factors associated with this disease. Of the animals tested, 5.20% (8/154 were positive. Among the risk factors evaluated, the presence of insects, permanence of the animals in agglomerations for longer than 8 hours per day, body condition, nutritional status, repeated use of the same needle among different equines, occurrence of febrile episodes, yellowish mucous and lack of knowledge on IEA showed to be statistically significant (P <0.05 associated with the IEA. The study results indicate that the occurrence of the IEA in traction equines in the City of São Luiz - MA was low. Still there is the necessity of systematic diagnosis and monitoring of animals, as well as employment of control measures, serological tests and implementation of current legislation.

    2006-01-01

    Full Text Available La Influenza Aviar es una enfermedad infecciosa que afecta principalmente a las aves, producida por virus de la gripe A, en la mayoría de los casos de baja patogenicidad. Debido a la rápida mutación de estos virus a formas altamente patógenas, el nivel de riesgo para la sanidad animal y la salud pública puede ser alto. Desde el año 2003, está teniendo lugar un brote de Influenza Aviar en aves producido por el subtipo H5N1 de alta patogenicidad, con transmisión y afectación humana y que presenta un riesgo potencial de producir una nueva pandemia de gripe. Ante estos brotes, es fundamental la colaboración entre los sectores implicados de la Sanidad Animal y Salud Pública que permita localizar con precisión las zonas de actividad de la enfermedad en los animales e intensificar en ellas la vigilancia de los casos en humanos. Las medidas de control de la enfermedad en animales deben ser compatibles con la reducción del riesgo de exposición humana. El objetivo de este artículo es hacer una revisión de las medidas generales desarrolladas contra la Influenza Aviar en aves, destacando los aspectos de coordinación y comunicación entre las autoridades de Sanidad Animal y Salud Pública, teniendo en cuenta que la legislación está sujeta a una renovación rápida y constante en consonancia con la dinámica de esta enfermedad.

    Full Text Available A endocardite infecciosa continua com alta mortalidade, apesar de sofisticados meios diagnósticos e terapêuticos. Mesmo com o uso de novos antibióticos, a sua evolução continua muitas vezes desfavorável, levando o paciente ao óbito ou a lesões incapacitantes. A operação deve ser realizada precocemente para evitar a alta mortalidade com o tratamento clínico isolado. Este estudo avalia o tratamento cirúrgico de pacientes com endocardite infecciosa e complicações de alto risco. Foram realizadas 63 operações cardíacas para tratar as complicações em pacientes com endocardite infecciosa, no HSE-RJ, entre maio de 1982 a outubro de 1995. Trinta e dois (62,3% pacientes apresentavam doença cardíaca prévia ou prótese valvar. A doença reumática foi encontrada em 24 (38,1% pacientes. Febre, sopros e insuficiência cardíaca estavam presentes em 100% dos casos. A ecocardiografia revelou a presença de vegetações ou destruição valvar em todos os casos. A cultura das valvas e a hemocultura foram positivas em 10 (15,6% e 29 (38,1% casos, respectivamente. O critério para o tratamento cirúrgico foi a insuficiência cardíaca intratável em 57 (90,5% casos, embolia sistêmica em 29 (46,0% pacientes e infecção persistente em 24 (38,1% casos. Foram implantadas 51 próteses mecânicas e 22 biopróteses. A valvulectomia tricúspide foi realizada em 4 pacientes. A mortalidade cirúrgica foi de 17,5% e todos os pacientes sobreviventes permaneceram em classe funcional I ou II, sem infecção.

    Full Text Available La endocarditis infecciosa es una enfermedad de baja incidencia que en las últimas décadas mostró modificaciones respecto de su presentación, posibilidad diagnóstica y tratamiento. A pesar de estos avances, la mortalidad hospitalaria sigue siendo muy elevada. Nuestro objetivo fue analizar las características de los pacientes con endocarditis infecciosa activa y su relación con la mortalidad hospitalaria a lo largo de 16 años. Se realizó un registro prospectivo entre 1994 y 2010 de pacientes ingresados con endocarditis. Se analizaron características clínicas, evolución y tratamiento y se registraron los eventos intrahospitalarios. Ingresaron 152 pacientes, 64.5% varones, edad 45 ± 16 años, las causas más frecuentes de cardiopatía de base fueron: congénita 32 (21% y reumática 20 (13.2%. Los motivos de internación fueron síndrome febril 116 (76.3% e insuficiencia cardíaca 61 (40.1%. Se identificó el agente infeccioso en 106 (69.7% de los casos, el más frecuente fue Streptococcus viridans. El ecocardiograma mostró vegetaciones en 123 (80.9% de los pacientes y 88 (57.8% presentaron complicaciones durante su internación, siendo la más frecuente la insuficiencia cardíaca. Se indicó tratamiento quirúrgico en 96 (63.1% de los casos, fundamentalmente por insuficiencia cardíaca en 66. La mortalidad hospitalaria global fue 46 (30.2%. El desarrollo de complicaciones en la internación, la indicación de cirugía y la presencia de insuficiencia cardíaca refractaria al tratamiento fueron predictores independientes de mortalidad hospitalaria, mientras que la presencia de vegetaciones resultó un predictor independiente de mejor supervivencia. La identificación temprana de estos predictores descriptos podría ayudar a mejorar los resultados.

A espécie aviar apresenta peculiaridades em seu proteoma neuronal, visto a presença de uma expressão diferenciada de proteínas chaves no metabolismo energético cerebral, algumas destas (VDAC1 e VDAC2 desempenham papel importante na compreensão do mecanismo da epilepsia refratária. A metodologia estabelecida no presente estudo obteve cultivo de neuroeferas, onde as células cresceram tipicamente em aglomerados atingindo, dentro de 7 dias, o diâmetro ideal de 100-200 µm. A diferenciação celular das neuroesferas foi obtida após a aderência destas às placas tratadas com poli-D-lisina, evidenciada pela migração de fibras do interior da neuroesfera. Ao contrário das neuroesferas, os neurônios em cultivo extenderam seus neuritos após 11 dias de isolamento. Tal modelo in vitro pode ser utilizado com sucesso na identificação das variáveis neuroproteômicas, propiciando uma avaliação global das alterações dinâmicas e suas interações protéicas. Tal modelo pode ter aplicações em estudos dos efeitos de indutores da morte celular e bloqueadores de canais de membrana mitocondriais em proteínas chaves do metabolismo energético cerebral.

    Sideroblastic anemias are a heterogenous group of disorders characterized by the presence of sideroblasts in the bone marrow aspirate. Current classification schemes distinguish between diseases of the heme synthesis pathway and diseases of other mitochondrial pathways which can either be of primary origin (defects in mitochondrial DNA) or of secondary origin (defects in nuclear DNA). Although several distinct hereditary forms exist, sideroblastic anemias are most frequently acquired diseases and belong to the group of myelodysplastic syndromes with the propensity to develop into overt leukemia. Treatment is mainly supportive (vitamins, blood transfusions, cytokines) and only rarely are bone marrow transplantations performed. The molecular defects of a few hereditary forms have already been elucidated, but the genes involved in the acquired forms are still largely unknown.

    Hemodynamic changes occur in pregnancy to prepare for expected blood loss at delivery. Physiologic anemia occurs in pregnancy because plasma volume increases more quickly than red cell mass. Anemia is most commonly classified as microcytic, normocytic, or macrocytic. Iron deficiency anemia accounts for 75% of all anemias in pregnancy. Oral iron supplementation is the recommended treatment of iron deficiency anemia in pregnancy. Parenteral iron and erythropoietin can also be used in severe or refractory cases. Outcomes and treatments for other forms of inherited and acquired anemias in pregnancy vary by disease, and include nutritional supplementation, corticosteroids, supportive transfusions, and splenectomy.

CASUÍSTICA E MÉTODOS: Entre janeiro de 1987 e janeiro de 1999, 159 pacientes foram operados em nosso Serviço, sendo 64,7% do sexo masculino. Este grupo apresentou idade média de 39,2 anos (2 a 78 anos, com peso médio de 57,1 kg. O acometimento valvar aórtico foi o mais freqüente (66 pacientes, sendo na valva nativa em 47 casos e em próteses em 19 (8 metálicas e 11 biológicas: a lesão mitral verificou-se em 53 pacientes, sendo mais comum em portadores de prótese (28 biológicas e 2 metálicas. O comprometimento das duas valvas esteve presente em 28 casos. Os demais pacientes eram portadores de defeitos congênitos ou de marcapasso definitivo. A operação foi indicada por refratariedade ao tratamento clínico, insuficiência cardíaca, quadro infeccioso levando a disfunção valvar ou de prótese, vazamento periprotético, ou ainda por arritmia. RESULTADOS: O estudo microbiológico evidenciou maior prevalência de infecção por Streptococcus viridans e Staphilococcus aureus. A operação realizada nos portadores de endocardite infecciosa em valva nativa propiciou a conservação da valva em 3 pacientes do grupo mitral e em 1 do grupo aórtico; nos demais pacientes empregaram-se próteses (a maioria metálica em aórticos e biológica em mitrais. As reoperações foram freqüentes, tendo pacientes com até quarta operação. A lesão congênita responsável pela maioria dos casos foi a comunicação interventricular (3 casos e 4 pacientes apresentavam a endocardite em eletrodo de marcapasso. A mortalidade global foi de 16,3%, com maior incidência em portadores de prótese mitral e aórtica submetidos a reoperação.

    1999-01-28

    We describe the four most common groups of neonatal anemia and their treatments, with particular emphasis on erythropoietin therapy. The hemolytic anemias include the ABO incompatibility (much more frequent, nowadays, than the Rh incompatibility, which has nearly disappeared following the use of anti-D immunoglobulin in postpartum Rh-negative mothers), hereditary spherocytosis and G-6-PD deficiency. Among hypoplastic anemias, that caused by Parvovirus B19 predominates, by far, over Diamond-Blackfan anemia, alpha-thalassemia and the rare sideroblastic anemias. "Hemorrhagic" anemias occur during twin-to-twin transfusions, or during feto-maternal transfusions. Finally, the multifactorial anemia of prematurity develops principally as a result of the rapid expansion of the blood volume in this group of patients. Erythropoietin therapy, often at doses much higher than those used in the adult, should be seriously considered in most cases of non-hypoplastic neonatal anemias, to minimise maximally the use of transfusions.

    Megaloblastic anemia is one of the acquired nutritional anemias that may complicate pregnancy. It is most often secondary to folic acid deficiency because folate requirements are increased during gestation. When the diagnosis of megaloblastic anemia is confirmed, appropriate therapy will initiate a rapid reversal of the anemia process. Because of the association between neural tube defects and folate deficiency, it is recommended that women of reproductive age take folic acid supplementation.

Los estudios llevados a cabo en nuestro país y en otros países demostraron que el perfil clínico del paciente ha cambiado. Existe mayor prevalencia de pacientes añosos con enfermedad degenerativa valvular, las endocarditis protésicas y nosocomiales son más frecuentes y aumentó la presencia del Staphylococcus aureus. Estos cambios podrían justificar la ausencia de disminución en la mortalidad de esta enfermedad y plantean la necesidad de encarar enfoques más agresivos de tratamiento mediante la confección de estudios prospectivos bien diseñados y controlados.In spite of the advance in diagnosis and antibiotic and surgical treatment, mortality of infective endocarditis remains high. Recent studies in various countries and in Argentina have shown that the clinical profile of infective endocarditis has changed. Currently the patients are older with higher frequency of degenerative valve disease and prosthetic valve and nosocomial endocarditis. The incidence of Staphylococcus aureus as etiological agent has increased. These changes may justify the absence of decrease in mortality and suggests that more aggressive measures are needed based on prospective, well designed and controlled trials.

    El optimismo de hace unos años con respecto al control definitivo de las enfermedades infecciosas ha venido diluyéndose poco a poco. Hoy en día, estas entidades nos atacan por múltiples frentes y, en conjunto, representan la principal causa de muerte a escala mundial. En 1995 17 millones de personas, incluidos 9 millones de niños, murieron por infecciones prevenibles como diarreas y neumonías. Los antibióticos, considerados hasta hace poco tiempo la solución al problema de las infecciones, son cada vez menos eficaces en la medida en que se incrementa el número de cepas resistentes y la velocidad con que éstas desarrollan dicha resistencia.

    Si a este hecho agregamos el evidente deterioro de las condiciones de vida de la población y el que ha sufrido la salud pública en particular, a consecuencia del desigual impulso a la más rentable atención de la enfermedad individual, la facilidad y rapidez con que se viaja de uno a otro continente o de una a otra región dentro de un país, la urbanización desordenada e incontrolada de las ciudades, la crisis económica mundial, los daños al ambiente, etc., todas condiciones que, en general, favorecen la aparición de “”nuevas” infecciones, puede entonces comprenderse la magnitud del desafío.

    Algunas de las enfermedades infecciosas emergentes, esto es, aquellas cuya incidencia en el Ser Humano ha aumentado durante los dos últimos decenios o amenaza con aumentar en el futuro próximo, han surgido a consecuencia de la evolución de microorganismos ya existentes como la tuberculosis o el cólera. Otras, quizás las menos, son ocasionadas por agentes hasta hace poco desconocidos (nuevos, varios de gran patogenecidad, como el virus de Ebola o Hantavirus que llevan a severas neumonías con letalidad del 50%.

    Full Text Available La endocarditis infecciosa es una enfermedad de baja incidencia que en las últimas décadas mostró modificaciones respecto de su presentación, posibilidad diagnóstica y tratamiento. A pesar de estos avances, la mortalidad hospitalaria sigue siendo muy elevada. Nuestro objetivo fue analizar las características de los pacientes con endocarditis infecciosa activa y su relación con la mortalidad hospitalaria a lo largo de 16 años. Se realizó un registro prospectivo entre 1994 y 2010 de pacientes ingresados con endocarditis. Se analizaron características clínicas, evolución y tratamiento y se registraron los eventos intrahospitalarios. Ingresaron 152 pacientes, 64.5% varones, edad 45 ± 16 años, las causas más frecuentes de cardiopatía de base fueron: congénita 32 (21% y reumática 20 (13.2%. Los motivos de internación fueron síndrome febril 116 (76.3% e insuficiencia cardíaca 61 (40.1%. Se identificó el agente infeccioso en 106 (69.7% de los casos, el más frecuente fue Streptococcus viridans. El ecocardiograma mostró vegetaciones en 123 (80.9% de los pacientes y 88 (57.8% presentaron complicaciones durante su internación, siendo la más frecuente la insuficiencia cardíaca. Se indicó tratamiento quirúrgico en 96 (63.1% de los casos, fundamentalmente por insuficiencia cardíaca en 66. La mortalidad hospitalaria global fue 46 (30.2%. El desarrollo de complicaciones en la internación, la indicación de cirugía y la presencia de insuficiencia cardíaca refractaria al tratamiento fueron predictores independientes de mortalidad hospitalaria, mientras que la presencia de vegetaciones resultó un predictor independiente de mejor supervivencia. La identificación temprana de estos predictores descriptos podría ayudar a mejorar los resultados.Active infective endocarditis (IE is a disease of low incidence that has showed changes in presentation, diagnosis and treatment options during the past decades.

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

    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 ..cap alpha..-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.

    Full Text Available Iron deficiency anemia (IDA is the most frequent form of anemia in pregnant women. Folic acid, vitamin B12 deficiency, and hemoglobinopathies are other causes of anemia in pregnancy. Finding the underlying cause are crucial to the management of the anemia. Anemia is defined as hemoglobin of <11 g/dl in the first and third trimester and <10.5 g/dl in second trimester. According to the literature, anemia, particularly severe anemia (Hb<7g/dl is associated with increased risk of maternal and perinatal mortality and morbidity, and long term adverse effects in the newborn. The association of hemoglobin levels to perinatal outcome has been shown to be U shaped with both high and low hemoglobin levels being associated adverse perinatal outcome such as low birth weight, increased stillbirths. Anemia in pregnancy is a major public health problem. Ideally a woman should have adequate iron stores when she conceives, in order meet to additional requirements of pregnancy. This review focuses on the occurrence, types, maternal and perinatal outcomes, prevention and treatment of anemia during pregnancy. [Archives Medical Review Journal 2013; 22(3.000: 300-316

    2010-01-01

    Full Text Available La influenza aviar es una enfermedad de gran importancia económica para la industria avícola. En México sólo se ha reportado la cepa H5N2 de baja patogenicidad y ésta se controla mediante la vacunación con virus inactivado. Esta vacuna en emulsión reduce la presencia de signos, pero no la eliminación viral. Desde hace más de 50 años se ha informado acerca de la eficacia del Factor de Transferencia (FT como inmunomodulador en casos clínicos humanos y en menor cantidad en modelos animales. El objetivo de este trabajo fue el de establecer la dosis que produce un mayor porcentaje de expresión del RNAm de dos citocinas: IL-2 y de IFN-γ. Se diseñó un experimento para evidenciar la expresión del RNAm de estas dos citocinas en pollos previamente inoculados con FT específico para influenza aviar. En la primera fase se aplicaron 0,1, 1, y 10 unidades de FT a diferentes grupos de pollos, posteriormente se realizó la PCR a partir de tejido esplénico. En la segunda fase se aplicó el FT junto con la vacuna a tres nuevos grupos de pollos. Del experimento 1 solamente IL-2 tuvo un porcentaje mayor de positivos (58,33% con 1 unidad (P < 0,05. En cambio, en el experimento 2, con 1 unidad se obtuvo 75% de positivos para IL-2 (P < 0,05 y 100% para IFN-γ (P < 0,01. De estos resultados su puede concluir que al aplicar una unidad de FT (equivalente a 7,3 μg de proteína al inicio del experimento y 10 días después otra unidad de FT junto con la vacuna inactivada de IA se indujo la expresión del RNAm de IFN-γ e IL-2.

  15. Purificação e caracterização da VDAC de mitocôndrias corticais aviares: identificação de modificações pós-traducionais nas porinas neuronais murinas e aviares

    2012-12-01

    Full Text Available A VDAC é uma porina presente na MME cuja função é crucial no metabolismo energético, sobrevivência e morte celular. A caracterização da VDAC torna-se importante para a compreensão das inter-relações da mitocôndria com os diferentes componentes citosólicos, tais como a HK. A ligação HK-VDAC favorece a utilização do ATP intramitocondrial em células neuronais, a HK cerebral pode interagir de formas diferentes com a VDAC, o que resulta em diferentes sítios de ligação (sítios A e B. Os variados papéis metabólicos das isoformas da VDAC podem ser explicados pela presença de alterações pós-traducionais. No presente trabalho purificamos a VDAC1 mitocondrial neuronal proveniente de cérebro aviar. Paralelamente, comprovamos que a presença de múltiplas formas das VDACs 1 e 2 em cérebros murino e aviar, seja devida à presença de modificações pós-traducionais, nomeadamente a fosforilação. A proteína isolada apresentou peso molecular de 30KDa. Quando submetida à eletroforese e posteriormente à coloração para a identificação de fosfoproteínas, a mesma mostrou-se desfosforilada. O conhecimento da presença, ou ausência de fosforilação das VDACs, reside na importância de estabelecer-se as bases moleculares ligadas à existência de sítios A e B nas mitocôndrias neuronais.

    Full Text Available La malaria es una enfermedad infecciosa de transmisión vectorial, que compromete enormemente la salud y el desarrollo socioeconómico de comunidades localizadas en regiones tropicales y subtropicales de todo el mundo. Se estima que globalmente, se registran cerca de 500 millones de casos clínicos cada año, los cuales son producidos por 4 especies diferentes de Plasmodium, siendo las más prevalentes las infecciones por P. falciparum y el P. vivax. Las manifestaciones clínicas de la malaria son bastantes pleomórficas y se pueden extender desde episodios febriles de corta duración, si el diagnóstico es oportuno y el tratamiento efectivo, hasta complicaciones sistémicas severas y muerte. Parte muy importante de la morbi-mortalidad está asociada con el desarrollo de anemia, una de las manifestaciones clínicas más frecuentes y uno de los mayores obstáculos para el desarrollo de las áreas endémicas por el compromiso que produce en el rendimiento escolar de los niños y en la productividad de los adultos. La fisiopatología de la anemia no se conoce completamente, pero se acepta que es producida por múltiples mecanismos que incluyen la destrucción de eritrocitos infectados y no infectados, la eritro-fagocitosis y un freno potencial de la eritropoyesis. La anemia aumenta significativamente la severidad y por consiguiente la mortalidad de la enfermedad y su tratamiento no siempre está dirigido a solucionar la causa de la misma. Este artículo discute los mecanismos involucrados en la producción de anemia en la malaria conocidos hasta el momento, el tratamiento y las implicaciones potenciales de vacunas dirigidas a prevenir esta complicación.

    Green, Ralph; Dwyre, Denis M

    2015-10-01

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

    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.

  14. Enfermedades infecciosas emergentes: interacción entre el mundo microbiano y las sociedades humanas

    Directory of Open Access Journals (Sweden)

    Fernando García

    2008-09-01

    Full Text Available En este artículo se analizan dos facetas importantes de las enfermedades infecciosas emergentes. Por un lado, las características de los microorganismos que las causan, por otro, las características del ser humano que promueven o contribuyen al surgimiento de las enfermedades infecciosas. Desde el punto de vista microbiano, se pueden identificar tres aspectos fundamentales. Primero, los patógenos emergentes son predominantemente virales, seguidos por los bacterianos. Numéricamente los virus ARN dominan, constituyendo el 37% de todos los patógenos emergentes. Los virus ARN predominan entre los virus patógenos emergentes que aparentemente entraron en las poblaciones humanas en las últimas décadas, como VIH y el coronavirus asociado al SARS. Segundo, los patógenos emergentes no se asocian a un único tipo de hospedero, sino que usualmente tienen amplio rango de hospederos que incluye varios órdenes de especies de mamíferos y no mamíferos. En efecto, la mayoría de las infecciones emergentes son de origen zoonótico. Tercero, los patógenos emergentes tienen un cierto grado de flexibilidad biológica que les permite aprovecharse de nuevas oportunidades epidemiológicas para ingresar a las poblaciones humanas. Las enfermedades infecciosas no son un problema reciente sino que han estado "emergiendo" a lo largo de la historia de la humanidad y es posible identificar, al menos, cuatro transiciones históricas. La última de esas transiciones es la globalización actual. Muchos factores antropogénicos inciden en el surgimiento de las enfermedades infecciosas emergentes, incluyendo eventos sociales, comportamiento humano, cambios ambientales, políticas en salud pública, procedimientos médicos y otros.

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

    Iron refractory iron deficiency anemia is a hereditary recessive anemia due to a defect in the TMPRSS6 gene encoding Matriptase-2. This protein is a transmembrane serine protease that plays an essential role in down-regulating hepcidin, the key regulator of iron homeostasis. Hallmarks of this disease are microcytic hypochromic anemia, low transferrin saturation and normal/high serum hepcidin values. The anemia appears in the post-natal period, although in some cases it is only diagnosed in ad...

  10. Evaluation of anemia in children.

    Science.gov (United States)

    Janus, Jennifer; Moerschel, Sarah K

    2010-06-15

    Anemia is defined as a hemoglobin level of less than the 5th percentile for age. Causes vary by age. Most children with anemia are asymptomatic, and the condition is detected on screening laboratory evaluation. Screening is recommended only for high-risk children. Anemia is classified as microcytic, normocytic, or macrocytic, based on the mean corpuscular volume. Mild microcytic anemia may be treated presumptively with oral iron therapy in children six to 36 months of age who have risk factors for iron deficiency anemia. If the anemia is severe or is unresponsive to iron therapy, the patient should be evaluated for gastrointestinal blood loss. Other tests used in the evaluation of microcytic anemia include serum iron studies, lead levels, and hemoglobin electrophoresis. Normocytic anemia may be caused by chronic disease, hemolysis, or bone marrow disorders. Workup of normocytic anemia is based on bone marrow function as determined by the reticulocyte count. If the reticulocyte count is elevated, the patient should be evaluated for blood loss or hemolysis. A low reticulocyte count suggests aplasia or a bone marrow disorder. Common tests used in the evaluation of macrocytic anemias include vitamin B12 and folate levels, and thyroid function testing. A peripheral smear can provide additional information in patients with anemia of any morphology.

    Directory of Open Access Journals (Sweden)

    Anca Ghiațău

    2015-08-01

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

    Full Text Available OBJETIVO: Descrever o caso de uma criança com endocardite infecciosa causada por Haemophilus aphrophilus. DESCRIÇÃO: Menino com febre e calafrios há 20 dias. À internação, apresentava-se febril, descorado e sem sinais de instabilidade hemodinâmica; à ausculta cardíaca, tinha sopro holosistólico em foco mitral. Os exames laboratoriais identificaram anemia (hemoglobina = 9,14 g/dL, leucócitos totais de 11.920 mm³, plaquetas de 250.000 mm³, velocidade de sedimentação das hemácias e proteína C reativa elevadas. O ecocardiograma revelou imagem em válvula mitral, sugestiva de vegetação. Com a hipótese de endocardite, foi iniciada antibioticoterapia com penicilina cristalina (200.000 UI/kg/dia associada à gentamicina (4 mg/kg/dia. No terceiro dia de tratamento, foi identificado Haemophilus aphrophilus em hemoculturas, sendo então trocado o esquema antibiótico para ceftriaxona (100 mg/kg/dia. No 20º dia de internação, encontrava-se pálido, mas sem febre e sem outras queixas. Os exames mostravam hemoglobina = 7,0 g/dL, leucócitos = 2.190 mm³, plaquetas = 98.000 mm³, razão normatizada internacional = 1,95 e R = 1,89. Foi feita hipótese de reação adversa ao ceftriaxona, que foi substituído por ciprofloxacina, 20 mg/kg/dia, até completar 6 semanas de tratamento. Após 72 horas da troca, houve normalização dos exames. Durante seguimento ambulatorial, apresentou insuficiência mitral grave, sendo submetido a troca de válvula por prótese metálica 9 meses após quadro agudo. Há 3 anos encontra-se bem, em acompanhamento ambulatorial. COMENTÁRIOS: É rara a identificação de agentes do grupo HACEK (Haemophilus ssp, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens e Kingella kingae em crianças com endocardite infecciosa. O caso apresentado, sem fatores de risco relacionados a esses agentes, reafirma a necessidade de tentar sempre identificar o agente etiológico das endocardites para

    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).

    Anemia is the most frequent derailment of physiology in the world throughout the life of a woman. It is a serious condition in countries that are industrialized and in countries with poor resources. The main purpose of this manuscript is to give the right concern of anemia in pregnancy. The most common causes of anemia are poor nutrition, iron deficiencies, micronutrients deficiencies including folic acid, vitamin A and vitamin B12, diseases like malaria, hookworm infestation and schistosomiasis, HIV infection and genetically inherited hemoglobinopathies such as thalassemia. Depending on the severity and duration of anemia and the stage of gestation, there could be different adverse effects including low birth weight and preterm delivery. Treatment of mild anemia prevents more severe forms of anemia, strictly associated with increased risk of fetal-maternal mortality and morbidity.

    2015-01-01

    The anemia of chronic disease is an old disease concept, but contemporary research in the role of proinflammatory cytokines and iron biology has shed new light on the pathophysiology of the condition. Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

    Introducción: Los niños con enfermedades respiratorias crónicas (ERC) tienen mayor riesgo de desarrollar anemia ferropriva, sin embargo, la ferropenia está infradiagnosticada. Objetivos: Describir el status de hierro (Fe) en niños con ERC y evaluar la respuesta a su suplementación profiláctica. Método: Estudio prospectivo de niños con ERC y adecuada ingesta de Fe en la dieta: se realizó hemograma, velocidad de eritro-sedimentación, proteína Creactiva y perfil de Fe. Posteriormente, aquellos con hemoglobina plasmática (Hb) normal no se suplementaron con Fe (Grupo A) y los que presentaban anemia ferropriva o factores de riesgo sí lo fueron (grupo B). Se evaluaron al 3º mes, después se suplementaron todos y se re-evaluaron al 4ºmes. Resultados: De 40 pacientes, con mediana de edad 30 meses (0,5 a 178), 60% eran hombres, 80% eutróficos. Requerían ventilación prolongada u oxigenoterapia 45%. Diagnósticos: 50% Bronquiolitis Obliterante post-infecciosa, 17,5% enfermedades de la vía aérea, 10% Displasia Broncopulmonar, 7,5% Fibrosis Quística y 15% otros. Basalmente 12,5% tuvo bajos depósitos de Fe y 20% anemia (la mayoría ferropriva). Completaron el estudio 25 niños: el grupo A disminuyó la ferritina sérica al 3ºmes (- 22,9 ± 30) y aumentó al 4ºmes (+12,8 ± 26) μg/L, (p = 0,013), sin cambio en la Hb. El grupo B tuvo ascenso de la Hb (91 ± 12 a 102 ± 12% del promedio para la edad, p = 0,04). Conclusión: La anemia ferropriva y la ferropenia son frecuentes en niños con ERC, quienes deterioran reversiblemente sus depósitos si no son suplementados. Sugerimos monitorizar con perfil de Fe y tratar precozmente, o suplementarlos en forma profiláctica.

    Full Text Available A endocardite infecciosa era fatal até há três gerações. A evolução temporal do conhecimento da doença possibilitou avanços nas técnicas diagnósticas, especialmente na ecocardiografia, a possibilidade de se realizar a cirurgia cardíaca, mesmo com o processo infeccioso em atividade, e novas recomendações de profilaxia por antibióticos antes dos procedimentos de intervenção. Hoje a endocardite infecciosa é curável. Nesta revisão são abordados os aspectos históricos da endocardite, desde as observações de Osler, no século XIX, até a transformação de doença "clinicamente possível" em "clinicamente definida".Infective endocarditis was a fatal disease three generations ago. Temporal evolution of knowledge made possible important advances in diagnostic techniques, especially in echocardiography, the possibility of cardiac surgery during the active infectious process and new guidelines for antibiotic prophylaxis before interventional procedures. Nowadays, infective endocarditis is curable. In this review, we describe historical aspects of endocarditis, from Osler´s observations in the 19th century to the change from a "clinically possible" to a "clinically defined" disease.

    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.

    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.

    Anemia is a common problem in obstetrics and perinatal care. Any hemoglobin below 10.5 g/dL can be regarded as true anemia regardless of gestational age. Reasons for anemia in pregnancy are mainly nutritional deficiencies, parasitic and bacterial diseases, and inborn red blood cell disorders such as thalassemias. The main cause of anemia in obstetrics is iron deficiency, which has a worldwide prevalence between estimated 20%-80% and consists of a primarily female population. Stages of iron deficiency are depletion of iron stores, iron-deficient erythropoiesis without anemia, and iron deficiency anemia, the most pronounced form of iron deficiency. Pregnancy anemia can be aggravated by various conditions such as uterine or placental bleedings, gastrointestinal bleedings, and peripartum blood loss. In addition to the general consequences of anemia, there are specific risks during pregnancy for the mother and the fetus such as intrauterine growth retardation, prematurity, feto-placental miss ratio, and higher risk for peripartum blood transfusion. Besides the importance of prophylaxis of iron deficiency, the main therapy options for the treatment of pregnancy anemia are oral iron and intravenous iron preparations.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Anemia is a form of blood disorder most often occurs in the community. Sickle cell anemia is anemia due to hemoglobinopathy caused by a change in the amino acid-6 of the ? globin chain. Sickle cell anemia is common in tropical areas of Africa and some parts of the region Saudi Arabia, India and the Mediterranean as well as black people in America. In addition there are also careers in various European countries. In pathophysiology, there are amino acid change from glutamic acid to valine in the ?-globin chain that causes red blood cells become sickle-shaped when deoxygenatied, but still be able to return to its normal shape when experiencing oxygenation. When the red blood cell membrane have been amended, the polymerization of red blood cells has become irreversible. Clinical picture seen in sickle cell anemia can be divided into two, namely: acute and chronic. Diagnosis can be done is to distinguish between heterozygous or homozygous sickle cell. Treatment provided in accordance with the clinical picture appears. Treatment that can be done is by blood transfusion, bone marrow transplant, anti-sickling drug delivery, and drug delivery to trigger the synthesis of HbF. Treatment still in the development stage is to use stem cells. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Full Text Available Una técnica de reacción en cadena de la polimerasa transcriptasa reversa (RT-PCR junto a una secuenciación fue usada para detectar y caracterizar genéticamente virus diferentes de bronquitis infecciosa aviar (VBIA aislados en Chile. El procedimiento de RT-PCR incluyó el uso de los partidores NT1 y NT2, los cuales se localizaron cerca del término N del gen S1 y cubrieron la región hipervariable. La secuencia amplificada fue alineada y analizada con el programa computacional DNAman, y comparada con secuencias reportadas en GenBank. El nivel de detección de la técnica de RT-PCR fue equivalente al aislamiento viral en huevos cuando se usaron directamente tejidos, pero el ensayo fue más sensitivo cuando fue usado para detectar virus almacenados en fluido alantoideo. Los amplificados de todos los aislados históricos de Chile fueron idénticos en tamaño (193pb y exhibieron entre ellos, al analizar la secuencia una similitud del 71 al 96%. Estos aislados mostraron entre 68 y 97% de similitud con cepas de Estados Unidos, Europa, Asia, Nueva Zelandia y Australia.A reverse transcriptase-polymerase chain reaction (RT-PCR assay, coupled with sequencing, was used to detect and genetically characterize different infectious bronchitis virus (IBV isolates in Chile.

FONTES DOS DADOS: Realizou-se uma revisão não sistemática nas bases de dados MEDLINE e LILACS, selecionando-se 66 referências mais relevantes. SÍNTESE DOS DADOS: Na bronquiolite obliterante pós-infecciosa ocorre lesão do epitélio respiratório, e a gravidade clínica está relacionada aos diferentes graus de lesão e ao processo inflamatório. O diagnóstico baseia-se no quadro clínico, na exclusão dos principais diagnósticos diferenciais e no auxílio dos exames complementares. A tomografia computadorizada de alta resolução, principalmente com imagens em inspiração e expiração, possibilta a avaliação das pequenas vias aéreas. As provas de função pulmonar caracterizam-se por padrão obstrutivo fixo com redução acentuada do FEF25-75%. O tratamento não está bem estabelecido, e o uso de corticoides tem sido preconizado em forma de pulsoterapia ou por via inalatória em elevadas doses, no entanto, os dados da literatura a respeito de sua eficácia ainda são escassos. O prognóstico a longo prazo é variável, podendo haver melhora clínica ou evolução para insuficiência respiratória crônica e óbito. CONCLUSÃO: A bronquiolite obliterante pós-infecciosa é uma doença que cursa com elevada morbidade e deve ser abordada por equipe multidisciplinar com acompanhamento em longo prazo.

    Warm autoimmune hemolytic anemia (AIHA) is defined as the destruction of circulating red blood cells (RBCs) in the setting of anti-RBC autoantibodies that optimally react at 37°C. The pathophysiology of disease involves phagocytosis of autoantibody-coated RBCs in the spleen and complement-mediated hemolysis. Thus far, treatment is aimed at decreasing autoantibody production with immunosuppression or reducing phagocytosis of affected cells in the spleen. The role of complement inhibitors in warm AIHA has not been explored. This article addresses the diagnosis, etiology, and treatment of warm AIHA and highlights the role of complement in disease pathology.

    Science.gov (United States)

    Brodsky, Robert A

    2015-01-01

    Complement is increasingly being recognized as an important driver of human disease, including many hemolytic anemias. Paroxysmal nocturnal hemoglobinuria (PNH) cells are susceptible to hemolysis because of a loss of the complement regulatory proteins CD59 and CD55. Patients with atypical hemolytic uremic syndrome (aHUS) develop a thrombotic microangiopathy (TMA) that in most cases is attributable to mutations that lead to activation of the alternative pathway of complement. For optimal therapy, it is critical, but often difficult, to distinguish aHUS from other TMAs, such as thrombotic thrombocytopenic purpura; however, novel bioassays are being developed. In cold agglutinin disease (CAD), immunoglobulin M autoantibodies fix complement on the surface of red cells, resulting in extravascular hemolysis by the reticuloendothelial system. Drugs that inhibit complement activation are increasingly being used to treat these diseases. This article discusses the pathophysiology, diagnosis, and therapy for PNH, aHUS, and CAD.

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

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

    2012-08-01

    Full Text Available A ceratoconjuntivite infecciosa (CI, embora raramente fatal, resulta em perdas econômicas significativas para os rebanhos bovinos e ovinos. Os principais agentes causadores dessa enfermidade são Moraxella bovis e Moraxella ovis. Em 2007 foi descrita uma nova espécie também responsável pela CI e denominada Moraxella bovoculi, que até o presente momento, não havia sido relatada no Brasil. Assim, objetivou-se com este trabalho caracterizar e distinguir 54 isolados de Moraxella spp. de amostras clínicas oriundas de 34 bovinos e 17 ovinos, encaminhadas ao Laboratório de Bacteriologia da Universidade Federal de Santa Maria no período de 1990 a 2011, visando a identificação de M. bovoculi. A distinção dos isolados foi fundamentada nas características genotípicas, pela amplificação parcial da região intergênica 16S-23S e clivagem dos produtos da amplificação com enzima RsaI. Como resultados, 25 (46% isolados foram caracterizados como M. bovis, 17 (32% como M. ovis e 12 (22% como M. bovoculi. Logo, conclui-se que M. bovoculi encontra-se presente no rebanho bovino do Rio Grande do Sul e, portanto, no Brasil.

    Full Text Available De 184 pacientes submetidos à ventrículo-auriculostomia com a válvula de Holter, 39 apresentaram complicações infecciosas. Em 18 casos ficou demonstrada a existência de ependimite e/ou meningite e em 21 instalou-se o quadro da bacteremia. Apesar das complicações, a ventrículo-auriculostomia continua a ser a técnica cirúrgica mais usada no tratamento da hidrocefalia. Com melhor seleção dos casos, excluindo-se doentes com meningite recente ou com fistula liquórica, os resultados poderão ser melhores. Ainda não se conseguiu método seguro para abolir a contaminação operatória. Nos casos em que existe ependimite deve-se iniciar tratamento antibiótico intensivo, seguido de retirada do sistema de drenagem. Nos doentes com bacteremia apenas, a remoção da válvula e cateteres dependerá da gravidade do caso e da resposta ao tratamento com antibióticos e corticosteróides, podendo ser adiada por algum tempo. Quando a infecção é causada por germe reconhecidamente patogênico há maior gravidade, devendo-se retirar precocemente o sistema de drenagem.

    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.

Por otro lado, el carácter complejo de los mecanismos de producción de la anemia en la enfermedad inflamatoria intestinal con frecuencia plantea dudas acerca del tratamiento más adecuado. La identificación correcta de los pacientes con anemia así como la instauración del tratamiento más idóneo serán los dos pilares fundamentales para la mejoría de la calidad de vida de los enfermos. El uso correcto de los suplementos de hierro y las nuevas formulaciones de hierro parenteral, con o sin eritropoyetina asociada, han revolucionado nuestro abordaje de esta complicación evolutiva de la enfermedad inflamatoria intestinalAnemia is a most common complication of inflammatory bowel disease. A high frequency of low hemoglobin values in these patients often leads physicians to subestimate this condition, which translates into ineffective treatment.

A correct identification of patients with anemia, and adequate therapy are the essential pillars for improved quality of life. The right use of iron supplementation, and novel parenteral iron formulations, either with or without associated erythropoietin, have revolutionized our approach of this complication in the course of inflammatory bowel disease

    2009-10-07

    Most anemia is related to the digestive system by dietary deficiency, malabsorption, or chronic bleeding. We review the World Health Organization definition of anemia, its morphological classification (microcytic, macrocytic and normocytic) and pathogenic classification (regenerative and hypo regenerative), and integration of these classifications. Interpretation of laboratory tests is included, from the simplest (blood count, routine biochemistry) to the more specific (iron metabolism, vitamin B12, folic acid, reticulocytes, erythropoietin, bone marrow examination and Schilling test). In the text and various algorithms, we propose a hierarchical and logical way to reach a diagnosis as quickly as possible, by properly managing the medical interview, physical examination, appropriate laboratory tests, bone marrow examination, and other complementary tests. The prevalence is emphasized in all sections so that the gastroenterologist can direct the diagnosis to the most common diseases, although the tables also include rare diseases. Digestive diseases potentially causing anemia have been studied in preference, but other causes of anemia have been included in the text and tables. Primitive hematological diseases that cause anemia are only listed, but are not discussed in depth. The last section is dedicated to simplifying all items discussed above, using practical rules to guide diagnosis and medical care with the greatest economy of resources and time.

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

Los gérmenes responsables de este tipo de infección pueden ser hongos, virus, bacterias y parásitos. Entre estas colonizaciones destaca por su frecuencia la candidiasis ocular, que se puede manifestar como una endoftalmitis de curso lento y larvado. El presunto síndrome de histoplasmosis ocular, aun siendo infrecuente en nuestro medio, es una causa importante de neovascularización coroidea. Los virus que con más frecuencia afectan la retina son del tipo herpes pudiendo producir un cuadro devastador en pacientes inmunocompetentes denominado síndrome de necrosis retiniana aguda. La retinitis por citomegalovirus es más frecuente en pacientes inmunodeprimidos como es el caso del SIDA, pero también se debe tener en cuenta en pacientes con linfoma y tratamiento inmunomodulador. Las enfermedades bacterianas más frecuentes que afectan la retina son la sífilis y la tuberculosis. La enfermedad por arañazo de gato, causada por una borrelia, puede producir una neuroretinitis.

    Full Text Available FUNDAMENTO: En nuestro país existen dos tipos de vacunas disponibles frente a la parotiditis infecciosa. En los últimos tiempos se han planteado dudas sobre la eficacia global de estas vacunas y de la eficacia comparada entre ambas (cepa Rubini y cepa Jeryl Lynn. En el distrito sanitario de A.P. "Sevilla Este" se registraron 256 casos durante 1997 (90,1 casos por 100.000 habitantes. Con este estudio se pretende aprovechar la aparición de casos de parotiditis para evaluar poblaciones afectadas e incidencia comparada según tipo de vacuna recibida durante la infancia. MÉTODOS: Análisis descriptivo de los casos (edad, distribución territorial, antecedentes vacunales,... y análisis evolutivo (tasas de incidencia anuales en el distrito sanitario y su entorno. Se evalúa la efectividad global de las vacunas frente a la parotiditis. Igualmente se estiman las tasas de incidencia de casos entre los vacunados con cepa Rubini y Jeryl Lynn. RESULTADOS: Se observan las tasas de incidencias más elevadas en niños entre 1 y 4 años. Se han estimado niveles de efectividad global para estas vacunas. Además se observa una incidencia de casos significativamente más elevada entre los niños vacunados con cepa Rubini que en los que lo hicieron con Jeryl Lynn (riesgo relativo de 6,5 con Intervalo de confianza 95% 3,6-11,8. CONCLUSIONES: La efectividad que se desprende de este estudio no parece ser tan buena como la eficacia teórica preconizada para las vacunas frente a la parotiditis. Se plantea la conveniencia de realizar otros estudios de casos según tipos de vacunas utilizadas. Igualmente son de gran interés los datos a suministrar por estudios seroepidemiológicos.

    Full Text Available A presença de processos infecciosos de repetição durante a prática de atividade física, tanto em nível competitivo quanto não-competitivo, impede a sua realização. Por isso, é muito importante recomendar ao desportista que evite o exercício muito intenso e competições nessas condições. O retorno à prática desportiva será realizado gradualmente, a uma intensidade proporcional à gravidade do processo infeccioso e ao número de dias que durou a infecção. As doenças respiratórias (agudas, crônicas e outras e as cutâneas (produzidas por bactérias, vírus, fungos e parasitos são, pela sua freqüência, as mais importantes entre os desportistas. Sem entrar nos detalhes etiológicos, clínicos e terapêuticos dessas infecções, focalizaremos as normas que regulam o retorno à atividade física e, em muitos casos, a participação em nível competitivo. É preciso classificar os esportes conforme o grau de contato ou colisão entre os participantes e de acordo com a intensidade do esforço que é realizado. Dessa forma, é estabelecida uma base que permite definir a relação entre o tipo de infecção e a participação desportiva. Também é necessário levar em conta algumas regras a serem seguidas no tratamento e recuperação das doenças infecciosas do desportista amador e de elite.

    2006-01-01

    Full Text Available Los péptidos antimicrobianos son moléculas efectoras clave en la inmunidad innata. Generalmente contienen de 15 a 45 residuos de aminoácidos y en su gran mayoría poseen carga positiva, además de que tienen la propiedad de ser anfipáticos. Estos péptidos son secretados por células epiteliales y leucocitos, como es el caso de los macrófagos y neutrófilos. En la actualidad, con base en la traducción de secuencias en programas computacionales se han descrito más de 800 tipos de péptidos antimicrobianos distribuidos en los reinos animal y vegetal. Estos péptidos pueden ser clasificados de acuerdo con su conformación estructural y la ubicación de sus puentes disulfuro. Las defensinas constituyen uno de los tipos de péptidos antimicrobianos más estudiados, y se dividen en dos familias de acuerdo con la ubicación de sus puentes disulfuro: alfa-defensinas y beta-defensinas. Algunas de estas defensinas pueden ser inducidas por citocinas proinflamatorias, así como por moléculas propias de patógenos, y se ha observado que están relacionadas con la inmunopatogenia de varias enfermedades. El papel principal de los péptidos antimicrobianos es la lisis directa de microorganismos; sin embargo, a la fecha también se han descrito propiedades quimiotácticas, que le permiten modular el sistema inmune y de esta forma constituir un puente entre la inmunidad innata y la inmunidad adaptativa. Actualmente se han iniciado estudios con la posibilidad de utilizar esta clase de moléculas como nuevos fármacos en diferentes tipos de enfermedades infecciosas.

    Science.gov (United States)

    Harigae, Hideo; Furuyama, Kazumichi

    2010-10-01

    Sideroblastic anemia is characterized by anemia with the emergence of ring sideroblasts in the bone marrow. Ring sideroblasts are erythroblasts characterized by iron accumulation in perinuclear mitochondria due to impaired iron utilization. There are two forms of sideroblastic anemia, i.e., inherited and acquired sideroblastic anemia. Inherited sideroblastic anemia is a rare and heterogeneous disease caused by mutations of genes involved in heme biosynthesis, iron-sulfur (Fe-S) cluster biogenesis, or Fe-S cluster transport, and mitochondrial metabolism. The most common inherited sideroblastic anemia is X-linked sideroblastic anemia (XLSA) caused by mutations of the erythroid-specific δ-aminolevulinate synthase gene (ALAS2), which is the first enzyme of heme biosynthesis in erythroid cells. Sideroblastic anemia due to SLC25A38 gene mutations, which is a mitochondrial transporter, is the next most common inherited sideroblastic anemia. Other forms of inherited sideroblastic anemia are very rare, and accompanied by impaired function of organs other than hematopoietic tissue, such as the nervous system, muscle, or exocrine glands due to impaired mitochondrial metabolism. Moreover, there are still significant numbers of cases with genetically undefined inherited sideroblastic anemia. Molecular analysis of these cases will contribute not only to the development of effective treatment, but also to the understanding of mitochondrial iron metabolism.

    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

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

    Full Text Available A normocytic normochromic anemia is one of the first signs of renal failure. Since anemia increases morbidity and mortality, its elimination is one of the essential objectives of the treatment. Human recombinant erythropoietin (rHuEPO has changed the therapeutical approach to anemia. The aim of the present study was to compare efficacy of anemia correction in peritoneal dialysis patients depending on treatment and dialysis modality. The study is the retrospective analysis of 64 patients who presented to our Clinic in 2003. Eighteen (28.13% patients were treated with rHuEPO, 14 (28% underwent continuous ambulatory peritoneal dialysis (CAPD, 2 (100% - automated peritoneal dialysis (APD and 2 (33.3% - intermittent peritoneal dialysis (IPD. Mean hemoglobin level was 98.6±17.82 g/l in patients treated with rHuEPO versus 98.81±15.14 g/I in patients without rHuEPO treatment. Erythropoietin requirements were 3392.85±1211.77 IU/week. AII patients received iron supplementation during rHuEPO therapy. Mean serum ferritin levels were 463.41 ±360 μg/l. Transferrin saturation (TSAT was 0.35±0.16%. No difference of serum iron and TSAT levels was found between CAPD and IPD patients. The degree of anemia significantly differed between CAPD and IPD patients. A total of 17.11% of PD patients were given blood transfusions, most frequently during the first three months after the onset of dialysis. Our conclusion is that the number of patients receiving rHuEPO should be increased, as 50% of our patients should be substituted, while only 28% are being treated. As 50% of patients receiving rHuEPO failed to reach target Hgb levels, higher EPO doses should be considered. Iron stores should be continuously monitored, particularly in patients receiving rHuEPO, since iron deficiency is an important problem for patients undergoing peritoneal dialysis, especially during erythropoietin therapy. Oral iron supplementation is satisfactory in the majority of patients, and

    Science.gov (United States)

    Wahle, M

    2012-12-01

    One of the most frequent extra-articular organ manifestations in rheumatoid arthritis (RA) is anemia. As anemia in RA patients may result in severe symptoms and aggravation of other disease manifestations (e.g. arteriosclerosis), the influence on the course of RA is profound. However, the importance of anemia in RA patients is frequently underestimated. The etiology of anemia in RA is complex. Anemia of inflammation (AI) and iron deficiency anemia, alone or in combination are the most frequent forms of anemia in RA. Changes in iron metabolism are the leading causes of anemia in RA patients and mainly induced by the altered synthesis and function of hepcidin and ferroportin. Hepcidin, a peptide produced in the liver and immunocompetent cells, impairs the expression of ferroportin on iron-secreting cells, thus reducing iron bioavailability. The typical changes of iron metabolism and hepcidin synthesis in RA are induced by proinflammatory cytokines, primarily interleukin-6. Hence, the treatment of RA with cytokine antagonists has significant therapeutic implications on anemia in the context of inflammation and impaired iron metabolism.

    Full Text Available Aplastic anemia is a rare heterogeneous disorder of hematopoietic stem cells causing pancytopenia and marrow hypoplasia with the depletion of all types of blood cells. This results in anemia, neutropenia and thrombocytopenia, which pose a challenge to both surgical and anesthetic management of such cases. We report a child with aplastic anemia who sustained traumatic ulcer on the arm and underwent split-thickness skin grafting under general anesthesia. There are only two case reports on anesthetic considerations in aplastic anemia patients in the literature. The anesthetic management is challenging because of the rarity of the disease, associated pancytopenia and immunosuppression.

    We conducted a cross sectional study to investigate risk factors associated with severe anemia [hemoglobin (Hb) iron status among Nepali pregnant women. Socio-demographic, anthropometric, health and dietary data were collected from 3,531 women living in the southeastern plains of Nepal. Stool samples were analyzed for intestinal helminthes. Dark adaptation was assessed using the Night Vision Threshold Test (NVTT). Hb levels were measured in all subjects to detect anemia and the soluble transferrin receptor (sTfR) was measured among a subsample of 479 women. The iron status categories were: 1) normal (Hb> or = 11.0 g/dl and sTfR anemia without iron deficiency (Hbiron deficiency without anemia (Hb > or = 11.0 g/dl and sTfR>8.5 mg/l); and 4) iron deficiency anemia (IDA): (Hb8.5 mg/l). Factors associated with severe anemia and poor iron status were determined using logistic regression. Hookworm infection increased the risk for developing severe anemia [adjusted odds ratio (AOR): 4.26; 95% CI 1.67-10.89; piron deficiency with and without anemia. Intake of iron supplements as tablets and/or tonic was protective against severe anemia, anemia without iron deficiency and IDA. Dietary heme iron was significantly associated with iron deficiency without anemia (RRR: 0.1; 95% CI 0.02-0.47; panemia and associated nutrient deficiencies.

  4. Unexplained Aspects of Anemia of Inflammation

    Directory of Open Access Journals (Sweden)

    Elizabeth A. Price

    2010-01-01

    Full Text Available Anemia of inflammation (AI, also known as anemia of chronic inflammation or anemia of chronic disease was described over 50 years ago as anemia in association with clinically overt inflammatory disease, and the findings of low plasma iron, decreased bone marrow sideroblasts and increased reticuloendothelial iron. Pathogenic features underlying AI include a mild shortening of red cell survival, impaired erythropoietin production, blunted responsiveness of the marrow to erythropoietin, and impaired iron metabolism mediated by inflammatory cytokines and the iron regulatory peptide, hepcidin. Despite marked recent advances in understanding AI, gaps remain, including understanding of the pathogenesis of AI associated with “noninflammatory” or mildly inflammatory diseases, the challenge of excluding iron deficiency anemia in the context of concomitant inflammation, and understanding more precisely the contributory role of hepcidin in the development of AI in human inflammatory diseases.

    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.

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

    Iron-deficiency anemia is the most common anemia in infants. In the routine pediatric care this problem is encountered every day. Numerous factors in infancy (low birth weight, rapid growth, insufficient nutrition) are involved in the development of iron-deficiency anemia, and they must be considered when establishing diagnosis, counselling parents, and prescribing oral iron preparations. Data on 119 patients aged up to two years treated in the Division of Gastroenterology and Nutrition, Pediatric Department, University Hospital Centre Zagreb Salata between 1994 and 1999, were analyzed. We were prompted to do so because of great frequency of iron-deficiency anemia as one of associated diagnoses, and unfortunately often the only diagnosis requiring hospitalization. Out of 119 patients with iron-deficiency anemia, nine (7.7%) patients (four premature newborns and three from twin pregnancy) had to receive transfusion of erythrocyte concentrate due to very bad general condition and low red blood count, accompanied by clinical signs of anemic hypoxia. We also analyzed prenatal and perinatal history, socioeconomic living conditions of these children, i.e. their nutrition, and if they had previously received oral iron preparations. Some of the results, such as inadequate alimentation with flour, as well as insufficient prophylaxis of iron deficiency, which were found in most cases of severe anemia, point to the need of paying greater attention to this problem, better parents education, and more adequate screening for iron deficiency anemia.

    Full Text Available The numbers of older people in the world have been growing rapidly. Anemia is the most common hematologic problem encountered in older adults. However, anemia should not be accepted as an inevitable consequence of aging. Anemia in the elderly signifies an underlying disease. Iron Defi ciency Anemia (IDA is being one of the most common causes of anemia in older people. IDA in the elderly is often associated with such non specific symptoms. The diagnosis of IDA is typically based on laboratory results. Hence, the utilization of the various laboratory tests plays an important role for the diagnosis of IDA. The presence of IDA in the elderly is usually related with gastrointestinal disorders. Thus,  gastrointestinal evaluation should be contemplated in all patients with IDA unless there is a history of clinically important non gastrointestinal blood loss. Older people with IDA should have iron supplementation both to correct anemia and to replenish body iron stores. However, the underlying cause should always be treated to prevent further iron loss.

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

    Rosse, Wendell F; Hillmen, Peter; Schreiber, Alan D

    2004-01-01

    Hemolytic anemia due to immune function is one of the major causes of acquired hemolytic anemia. In recent years, as more is known about the immune system, these entities have become better understood and their treatment improved. In this section, we will discuss three areas in which this progress has been apparent. In Section I, Dr. Peter Hillmen outlines the recent findings in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH), relating the biochemical defect (the lack of glycosylphosphatidylinositol [GPI]-linked proteins on the cell surface) to the clinical manifestations, particularly hemolysis (and its effects) and thrombosis. He discusses the pathogenesis of the disorder in the face of marrow dysfunction insofar as it is known. His major emphasis is on innovative therapies that are designed to decrease the effectiveness of complement activation, since the lack of cellular modulation of this system is the primary cause of the pathology of the disease. He recounts his considerable experience with a humanized monoclonal antibody against C5, which has a remarkable effect in controlling the manifestations of the disease. Other means of controlling the action of complement include replacing the missing modulatory proteins on the cell surface; these studies are not as developed as the former agent. In Section II, Dr. Alan Schreiber describes the biochemistry, genetics, and function of the Fc gamma receptors and their role in the pathobiology of autoimmune hemolytic anemia and idiopathic thrombocytopenic purpura due to IgG antibodies. He outlines the complex varieties of these molecules, showing how they vary in genetic origin and in function. These variations can be related to three-dimensional topography, which is known in some detail. Liganding IgG results in the transduction of a signal through the tyrosine-based activation motif and Syk signaling. The role of these receptors in the pathogenesis of hematological diseases due to IgG antibodies is

  17. [A simple algorithm for anemia].

    Science.gov (United States)

    Egyed, Miklós

    2014-03-09

    The author presents a novel algorithm for anaemia based on the erythrocyte haemoglobin content. The scheme is based on the aberrations of erythropoiesis and not on the pathophysiology of anaemia. The hemoglobin content of one erytrocyte is between 28-35 picogram. Any disturbance in hemoglobin synthesis can lead to a lower than 28 picogram hemoglobin content of the erythrocyte which will lead to hypochromic anaemia. In contrary, disturbances of nucleic acid metabolism will result in a hemoglobin content greater than 36 picogram, and this will result in hyperchromic anaemia. Normochromic anemia, characterised by hemoglobin content of erythrocytes between 28 and 35 picogram, is the result of alteration in the proliferation of erythropoeisis. Based on these three categories of anaemia, a unique system can be constructed, which can be used as a model for basic laboratory investigations and work-up of anaemic patients.

    Sideroblastic anemias are caused by a diversity of hereditary, congenital, or acquired disorders. Criteria used in describing sideroblastic anemias vary widely among standard medical textbooks and even so have been imprecisely applied in the literature. Recent discoveries concerning the basic pathophysiologic mechanisms involving the molecular biology of nuclear and mitochondrial DNA, erythroid ALA synthase (ALAS-2), and iron transport have made the classification of sideroblastic anemias very complex. We recommend a more precise evaluation and documentation of the components that characterize the sideroblastic abnormality and propose an extended classification of the sideroblastic anemias.

    Full Text Available PURPOSE: Involvement of the cornea endothelium during uveitis has not been extensively studied even though it might participate in or constitute a target of ocular inflammation. Formation of keratic precipitates (KP is a characteristic finding in several forms of uveitis. The aim of this prospective study was to examine the vicinity of keratic precipitates in infectious and noninfectious uveitis by specular microscopy. METHODS: Patients with infectious and noninfectious uveitis in any activity level and presence of keratic precipitates were enrolled. The mean age was 40.5 years (± 14.2 years. A Topcon SP-2000P noncontact specular microscope was used to capture endothelial images in the vicinity of keratic precipitates. Automated morphometric analysis was done for cell size, cell density and cells coefficient of variation. Statistical comparisons were made between the infectious and noninfectious groups. RESULTS: From the 25 patients enrolled in this study, 16 (44% eyes presented infectious uveitis, 19 (53% noninfectious uveitis and 1 (3% eye was excluded due to the impossibility to obtain a specular image. The mean cell density estimated was 2,628 ± 204 cells/mm² in infectious group and 2,622 ± 357 cells/mm² in noninfectious group. The mean cellular area in infectious and noninfectious group was respectively 385 ± 31 µm² and 390 ± 60 µm². The coefficient of variation (% of the cellular area in the vicinity of keratic precipitates was 26.36 ±3.44 in infectious and 27.69 ± 4.61 in noninfectious group. The differences between the groups were not statistically significant (POBJETIVO: Avaliar o endotélio corneano na presença de precipitados ceráticos em pacientes portadores de uveítes infecciosas e não-infecciosas com emprego da microscopia especular de não-contato.

    2015-09-01

    The classification of autoimmune hemolytic anemias and the complement system are reviewed. In autoimmune hemolytic anemia of the warm antibody type, complement-mediated cell lysis is clinically relevant in a proportion of the patients but is hardly essential for hemolysis in most patients. Cold antibody-mediated autoimmune hemolytic anemias (primary cold agglutinin disease, secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria) are entirely complement-mediated disorders. In cold agglutinin disease, efficient therapies have been developed in order to target the pathogenic B-cell clone, but complement modulation remains promising in some clinical situations. No established therapy exists for secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria, and the possibility of therapeutic complement inhibition is interesting. Currently, complement modulation is not clinically documented in any autoimmune hemolytic anemia. The most relevant candidate drugs and possible target levels of action are discussed.

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

    Summary 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 ph...

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

    Full Text Available Iron-deficiency anemia is a common reason for referral to a gastroenterologist. In adult men and postmenopausal women, gastrointestinal tract pathology is often the cause of iron-deficiency anemia, so patients are frequently referred for endoscopic evaluation. Endoscopy may be costly and at times difficult for the patient. Therefore, physicians need to know what lesions can be identified reliably and, more importantly, the importance of ruling out life-threatening conditions such as occult malignancy. Over the past decade, a number of prospective studies have been completed that examined the yield of endoscopy in the investigation of iron-deficiency anemia. The present article provides a broad overview of iron-deficiency anemia, with particular emphasis on hematological diagnosis, etiology, the use of endoscopy in identifying lesions and iron-repletion therapy. Other clinical scenarios, including assessment of patients on anti-inflammatory or anticoagulation therapy and patients with bleeding of obscure origin, are also addressed. The present article provides a diagnostic algorithm to iron-deficiency anemia, which describes a more systematic manner in which to approach iron-deficiency anemia.

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

    Sheftel, Alex D; Richardson, Des R; Prchal, Josef; Ponka, Prem

    2009-01-01

    Sideroblastic anemias are a heterogeneous group of disorders, characterized by mitochondrial iron overload in developing red blood cells. The unifying characteristic of all sideroblastic anemias is the ring sideroblast, which is a pathological erythroid precursor containing excessive deposits of non-heme iron in mitochondria with perinuclear distribution creating a ring appearance. Sideroblastic anemias may be hereditary or acquired. Hereditary sideroblastic anemias are caused by defects in genes present on the X chromosome (mutations in the ALAS2, ABCB7, or GRLX5 gene), genes on autosomal chromosomes, or mitochondrial genes. Acquired sideroblastic anemias are either primary (refractory anemia with ring sideroblasts, RARS, representing one subtype of the myelodysplastic syndrome) or secondary due to some drugs, toxins, copper deficiency, or chronic neoplastic disease. The pathogenesis of mitochondrial iron loading in developing erythroblasts is diverse. Ring sideroblasts can develop as a result of a heme synthesis defect in erythroblasts (ALAS2 mutations), a defect in iron-sulfur cluster assembly, iron-sulfur protein precursor release from mitochondria (ABCB7 mutations), or by a defect in intracellular iron metabolism in erythroid cells (e.g. RARS).

    2015-08-21

    Iron is an important micronutrient that may be depleted in celiac disease. Iron deficiency and anemia may complicate well-established celiac disease, but may also be the presenting clinical feature in the absence of diarrhea or weight loss. If iron deficiency anemia occurs, it should be thoroughly evaluated, even if celiac disease has been defined since other superimposed causes of iron deficiency anemia may be present. Most often, impaired duodenal mucosal uptake of iron is evident since surface absorptive area in the duodenum is reduced, in large part, because celiac disease is an immune-mediated disorder largely focused in the proximal small intestinal mucosa. Some studies have also suggested that blood loss may occur in celiac disease, sometimes from superimposed small intestinal disorders, including ulceration or neoplastic diseases, particularly lymphoma. In addition, other associated gastric or colonic disorders may be responsible for blood loss. Rarely, an immune-mediated hemolytic disorder with increased urine iron loss may occur that may respond to a gluten-free diet. Reduced expression of different regulatory proteins critical in iron uptake has also been defined in the presence and absence of anemia. Finally, other rare causes of microcytic anemia may occur in celiac disease, including a sideroblastic form of anemia reported to have responded to a gluten-free diet.

    Full Text Available Patients with chronic kidney diseases (CKDs and cardiovascular diseases (CVDs present with various degree of anemia. Anemia has been associated with poor outcome in patients with CKD and CVD. CVD is the commonest cause of morbidity and mortality in patients with CKD. CKD causes anemia and CVD, and this rapidly deteriorates when anemia is not corrected. This triad of CVD, CKD, and anemia has been termed cardio-renal-anemia syndrome. The objec-tive of this study is to highlight the importance of cardio-renal-anemia syndrome, their relation-ship, and management. Three patients with various stages of CKD who presented with anemia and cardiovascular abnormalities are reported. The patients responded well to various interventional measures, with improvement in their clinical and laboratory parameters. Cardio-renal-anemia syndrome is an entity that should be identified. Early and appropriate intervention leads to better outcome.

    The most common hematologic complication of inflammatory bowel disease (IBD)--ulcerative colitis and Crohn's Disease is anemia. Anemia in patients with IBD may be a result of iron, vitamin B12 or folate deficiency; anemia of chronic disease and hemolytic anemia are other causes in these patients. Factors contributing to the development of anemia include chronic gastrointestinal blood loss, vitamin B12 malabsorption secondary to terminal ileitis, folate deficiency as a result of sulfasalazine therapy. Approximately 30% of patients with IBD have hemoglobin levels below 12 g/dl. The risk of developing anemia relates to disease activity, given that blood loss and inflammatory anemia are triggered by intestinal inflammation. In the management strategy of IBD patients with anemia it is important to distinguish between the different types of anemia in order to decide an appropriate manner of treatment.

    Iron deficiency and anemia are associated with impaired neurocognitive development and immune function in young children. Total body iron, calculated from serum ferritin and soluble transferrin receptor concentrations, and hemoglobin allow for monitoring of the iron and anemia status of children in the United States. The purpose of this analysis is to describe the prevalence of iron deficiency (ID), anemia, and iron deficiency anemia (IDA) among children 1–5 years using data from the 2007–2010 National Health and Nutrition Examination Survey (NHANES). Prevalence of ID, anemia, and IDA among children 1–5 years was 7.1% (5.5, 8.7), 3.2% (2.0, 4.3), and 1.1% (0.6, 1.7), respectively. The prevalence of both ID and anemia were higher among children 1–2 years (p < 0.05). In addition, 50% of anemic children 1–2 years were iron deficient. This analysis provides an update on the prevalence of ID, anemia, and IDA for a representative sample of US children. Our results suggest little change in these indicators over the past decade. Monitoring of ID and anemia is critical and prevention of ID in early childhood should remain a public health priority. PMID:27249004

    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.

    2007-01-01

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

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

There is no pathognomonic sign for the diagnosis of the immune-mediated hemolytic anemia; however, laboratory findings show regenerative anemia, spherocytosis, positive results in Coombs' test and rarely, monocytes with hemosiderin or erythrocytes phagocytosis, but even with these findings, the primary and secondary IMHA can not be differentiate from each other. Differentiation can only be achieved when there is a deep investigation into the cause of the anemia.

    Inherited sideroblastic anemia comprises several rare anemias due to heterogeneous genetic lesions, all characterized by the presence of ringed sideroblasts in the bone marrow. This morphological aspect reflects abnormal mitochondrial iron utilization by the erythroid precursors. The most common X-linked sideroblastic anemia (XLSA), due to mutations of the first enzyme of the heme synthetic pathway, delta-aminolevulinic acid synthase 2 (ALAS2), has linked heme deficiency to mitochondrial iron accumulation. The identification of other genes, such as adenosine triphosphate (ATP) binding cassette B7 (ABCB7) and glutaredoxin 5 (GLRX5), has strengthened the role of iron sulfur cluster biogenesis in sideroblast formation and revealed a complex interplay between pathways of mitochondrial iron utilization and cytosolic iron sensing by the iron-regulatory proteins (IRPs). As recently occurred with the discovery of the SLC25A38-related sideroblastic anemia, the identification of the genes responsible for as yet uncharacterized forms will provide further insights into mitochondrial iron metabolism of erythroid cells and the pathophysiology of sideroblastic anemia.

    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.

    Anemia is one of the most common public health problems in developing countries like Nepal. This study was done to find the prevalence of anemia among the children aged 4-13 years in eastern Nepal. A cross-sectional study was conducted in 2012 in four districts (Morang, Udayapur, Bhojpur and Ilam) of eastern Nepal to find the prevalence of anemia among the school children of eastern Nepal. Children aged 4-13 years were selected randomly from different schools of above districts and 618 venous blood samples were collected. Hemoglobin level was estimated by using cyanmethemoglobin method. The mean hemoglobin level was 12.2 ± 1.82 gm/dl. About 37.9% (n = 234) children were found anemic. Anemia prevalence was 42.4% (n = 78), 31.6% (n = 60), 45.3% (n = 48) and 34.8% (n = 48) among school children of Morang, Udayapur, Bhojpur and Ilam district, respectively. The study finds anemia as a significant health problem among the school children of eastern Nepal.

    Iron is essential for life because it is indispensable for several biological reactions, such as oxygen transport, DNA synthesis, and cell proliferation. Over the past few years, our understanding of iron metabolism and its regulation has changed dramatically. New disorders of iron metabolism have emerged, and the role of iron as a cofactor in other disorders has begun to be recognized. The study of genetic conditions such as hemochromatosis and iron-refractory iron deficiency anemia (IRIDA) has provided crucial insights into the molecular mechanisms controlling iron homeostasis. In the future, these advances may be exploited to improve treatment of both genetic and acquired iron disorders. IRIDA is caused by mutations in TMPRSS6, the gene encoding matriptase-2, which downregulates hepcidin expression under conditions of iron deficiency. The typical features of this disorder are hypochromic, microcytic anemia with a very low mean corpuscular volume of erythrocytes, low transferrin saturation, no (or inadequate) response to oral iron, and only a partial response to parenteral iron. In contrast to classic iron deficiency anemia, serum ferritin levels are usually low-normal, and serum or urinary hepcidin levels are inappropriately high for the degree of anemia. Although the number of cases reported thus far in the literature does not exceed 100, this disorder is considered the most common of the "atypical" microcytic anemias. The aim of this review is to share the current knowledge on IRIDA and increase awareness in this field.

    Full Text Available Background: The aim of the present study was to find out the variation of pulmonary function parameters in different trimesters of pregnancy as well as variation according to severity of anemia in each trimester. Methods: The present case control study was carried out in the post-graduate department of obstetrics and gynecology, M.K.C.G. medical college and hospital, Berhampur, during the period from October 2012 to October 2013. This study entitled and ldquo;Pulmonary functions in pregnancy complicated with anemia and rdquo;, embodies the pulmonary functions of 60 anemic pregnant females (study group and 100 healthy pregnant females (control in different trimesters of pregnancy. The pulmonary function parameters, which were studied, are FVC, FEV1, FEV1/FVC, FEF25-75%, PEFR and MVV in both the study and control group. Results: Comparing the variation with advancing gestation in study and control, it was seen that FVC, FEV1, FEV1/FVC and FEF25-75% showed no significant alteration. With increasing severity of anemia compared to controls, FVC, FEV1, PEFR and MVV values reduce significantly. As FEF25-75% is not effort dependent, it shows no significant variation. Conclusion: Thus from this study, it can be concluded that moderate to severe anemia in pregnancy can adversely affect pulmonary functions. Hence nutritional anemia in early pregnancy should be provided with iron supplements in order to prevent adverse obstetric outcomes. [Int J Res Med Sci 2014; 2(4.000: 1431-1437

    Full Text Available Fanconi Anemia (FA is a rare autosomal recessive disorder affecting multiple body systems. The diagnosis is based on morphological abnormalities, hematological abnormalities (pancytopenia, macrocytic anemia and progressive bone marrow failure and genetic testing. However, genetic testing is complicated for FA because there are often many genes that are associated with its development, and large duplications, deletions or sequence variations are frequently observed in some of these genes. We report a patient with cytogenetically confirmed Fanconi anemia. Although morphological abnormalities were present from birth, diagnosis was suspected and made at 8 years of age when he presented to us. We report this case to create awareness among clinicians to use modern modalities of diagnosis for such cases in addition to the clinical assessment. This would further help these children reach their adulthood with good quality of life. [Int J Res Med Sci 2015; 3(4.000: 998-1001

    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.

    Hereditary sideroblastic anemia (HSA) is a heterogeneous group of inherited anemic disorders which is characterized by the presence of ringed sideroblasts in the bone marrow, microcytic hypochromic anemia and typically its X-linked inheritance in patients. It has been shown that a deficiency of the erythroid-specific delta-aminolevulinate synthase (ALAS-E) activity is responsible for pyridoxine-responsive HSA in many patients, however, the pathogenesis of other types of HSA remains still unknown. In this article, recent evidence suggesting multiple causes for HSA is summarized and discussed.

    The aim of the study was to evaluate the clinical efficiency of soluble transferrin receptor and transferrin receptor-ferritin index (sTfR/logF) in the diagnosis of iron deficiency anemia, as well as the differential diagnosis of iron deficiency anemia and anemia in rheumatoid arthritis. The study included 96 patients with anemia and 61 healthy volunteers as a control group. In healthy subjects there were no significant sex and age differences in the parameters tested. The study results showed these parameters to be reliable in the diagnosis of iron deficiency anemia, as well as in the differential diagnosis of iron deficiency anemia and anemia of chronic disease. The results indicate that sTfR/logF could be used to help differentiate coexisting iron deficiency in patients with anemia of chronic disease. Receiver operating characteristic analysis showed a higher discriminating power of transferrin receptor-ferritin index vs. soluble transferrin receptor in the diagnosis of iron deficiency anemia, as well as in the differential diagnosis between iron deficiency anemia and anemia of chronic disease. In patients with anemia in rheumatoid arthritis, the parameters tested showed no significant differences with respect to C-reactive protein concentration. These results suggested that the parameters tested are not affected by acute or chronic inflammatory disease.

    confirmada a través de una prueba de ADN raza específica para la inserción 6bp en el extremo 3' del exón 10 de la secuencia del gen de la piruvato quinasa eritrocitaria (R-PK como fue descrito. Al perro se le practicó eutanasia a los 20 meses de edad debido al deterioro de su estado clínico, el cual incluyó anemia e incompatibilidad sanguínea. En otros casos descritos en perros de la raza WHWT con esta deficiencia, existen relatos hasta de nueve años de sobrevivencia. Los defectos hereditarios deben ser objeto de diagnóstico diferencial importante en casos de anemias hemolíticas crónicas en animales jóvenes después de la exclusión diagnóstica de disturbios inmunomediados y causas infecciosas. Adicionalmente, perros de razas puras para las cuales la prueba de ADN está disponible para enfermedades hereditarias deben ser evaluados antes de la edad reproductiva para limitar la diseminación del alelo mutante y la generación futura de animales deficientes.

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

    A 59-year-old man was orally administered rabeprazole, a proton pump inhibitor (PPI), for gastroesophageal reflux disease, after which he gradually developed iron-deficiency anemia. The anemia did not improve following the administration of ferrous fumarate, and endoscopic screening of the entire gastrointestinal tract, including the small intestine, did not reveal any findings indicating the cause of the anemia. The patient was then switched from rabeprazole to famotidine and the anemia was cured within three months. There is much debate as to whether the long-term use of PPIs causes iron-deficiency. However, this case strongly suggests that PPIs can induce iron-deficiency anemia.

    Hemolytic anemia has been reported to occur in the setting of aortic stenosis and prosthetic heart valves, but much more rarely in association with obstructive hypertrophic cardiomyopathy (HC). Of the few descriptions of hemolytic anemia secondary to HC, all but one case involved bacterial endocarditis contributing to left ventricular outflow tract obstruction. We present the case of a 67-year-old man with recurrent hemolytic anemia and HC, without infective endocarditis. Attempts at iron repletion and augmentation of beta-blocker therapy proved his anemia to be refractory to medical management. Ventricular septal myectomy led to the resolution of hemolysis, anemia, and its coexisting symptoms. PMID:26424952

    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.

    Autoimmune hemolytic anemia (AIHA) is diagnosed in the presence of anemia, usually macrocytic and of variable intensity, reticulocytosis, and a positive direct and/or indirect antiglobulin test, after ruling out other types of hemolytic anemia. A positive direct antiglobulin test alone is not sufficient to diagnose AIHA and may be positive in many patients without anemia or negative in some patients with AIHA. AIHA may be classified into two major categories according to the optimal temperature of antibody activity: warm-reacting autoantibodies (usually IgG) optimal around 37 degrees C and cold-reacting autoantibodies, optimal at 4 degrees C (usually IgM). This classification guides the selection of tests and treatment. AIHA is widely reported to be associated with a variety of other diseases, although these associations are often fortuitous. A minimal set of useful investigations is appropriate since AIHA may be secondary to viral infections, lymphoid malignancies, or autoimmune disorders such as lupus. Transfusion should remain rare in AHAI, but close contact with the transfusion service is necessary if it is to succeed. As for many autoimmune and/or systemic diseases, numerous types of treatment have been proposed but have not been validated in controlled multicenter studies. These are necessary to improve the management of these rare disorders.

    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 labora-tory 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 con-venient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD.

    Hereditary sideroblastic anemia is a very rare disease recessive and X-linked that affect heme biosynthesis by deficit or decreased of delta aminolevulinic acid synthase (ALAS) activity. We report a case of a six-month-old boy, admitted in the hospital for anemic syndrome. The hemogram showed anemia (hemoglobin: 4.5 g/dL), frankly hypochronic microcytic and a regenerated (mean corpuscular hemoglobin concentration: 26 g/dL, mean cell volume: 53 fl, reticulocytes: 10 x 10(9)/L) with red cells morphologic disorders in smears (anisopoikylocytosis) without attack of the other lineages; white blood cells: 11 x 10(9)/L (neutrophils: 64% and lymphocytes: 35%); platelets: 350 x 10(9)/L. Examination of bone marrow showed an important erythroid hyperplasia (about 69%) with dyserythropoiesis. Perls stain revealed intense siderosis with 90% of ringed sideroblasts and a large number of siderocytes. Exploration of ALAS2 and ABC7 genes on the DNA of the infant was not found abnormalities. Treatment with pyridoxine corrects moderately the anemia. By the way, we proposed to remind that iron deficiency, inflammatory syndrome and thalassemia are the common microcytic anemia. However, it's mandatory to explore other causes if diagnosis is not solved.

    2001-05-01

    Hysterectomy is the second-most-common surgical procedure among premenopausal women. The conditions that lead to the need for a hysterectomy often are accompanied by chronic blood loss that can lead to anemia. Moreover, hysterectomy and myomectomy may result in significant blood loss, which exacerbates the anemia. The presence of fatigue associated with anemia has a substantially negative impact on quality of life and the ability to perform activities of daily living. Options for alleviating perioperative anemia include minimizing surgical blood loss, blood transfusion, supplementation with hematinics, such as iron and folic acid, and treatment with recombinant human erythropoietin. Treating preoperative anemia is expected to help correct anemia prior to surgery and may have a positive impact on anemia-related symptoms and surgical outcomes.

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

The purpose of this study was to elucidate the risk factors of neonatal anemia in placenta previa.Methods: The study was conducted on 158 placenta previa patients at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 through December 2009. The subjects were divided in to 2 groups: 47 placenta previa patients with neonatal anemia, and 113 placenta previa patients without neonatal anemia. The subjects' characteristics were compared. Logistic regression was used to control for confounding factors.Results: Anterior placental location (OR 2.48; 95% CI: 1.20-5.11 was an independent risk factor of neonatal anemia after controlling for potential confounders.Conclusion: To manage neonatal anemia in placenta previa patients, obstetricians should do their best to detect placental location. Pediatricians should consider the high possibility of neonatal anemia in cases involving anterior placental location.

    Full Text Available La uveítis se define como la inflamación del tracto uveal, aunque en la práctica clínica hace referencia a cualquier proceso inflamatorio intraocular. El origen de esta inflamación puede atribuirse a un mecanismo endógeno, ya sea formando parte de una enfermedad sistémica (sarcoidosis, enfermedad de Behçet, esclerosis múltiple, síndrome de Vogt-Koyanagi-Harada, etc. o de forma ocular aislada. En muchas ocasiones, la enfermedad ocular constituye la forma de comienzo de una enfermedad sistémica. Por otra parte, la afectación ocular constituye, en ocasiones, la principal causa de morbilidad derivada de la enfermedad, por lo que su diagnóstico y tratamiento precoz son de la máxima importancia para evitar secuelas irreversibles. En este artículo se revisan los aspectos clínicos, diagnósticos y terapéuticos más relevantes de la afectación ocular en el contexto clínico de las enfermedades sistémicas no infecciosas más comúnmente asociadas a uveítis.Uveitis can be defined as any inflammation affecting the uveal tract, although in clinical practice this term includes any intraocular inflammatory event. The etiology of this inflammation can be related to an endogenous mechanism in the clinical course of a systemic disease (sarcoidosis, Behçet’s disease, multiple sclerosis, Vogt-Koyanagi-Harada disease, etc., or an isolated ocular entity. Sometimes, ocular inflammation is the initial manifestation of an undiagnosed systemic disease. On the other hand, ocular involvement could be the main cause of morbidity of the disease, and early diagnosis and treatment is an important issue in order to avoid irreversible ocular damage. In this article, the authors review some relevant clinical, diagnostic and therapeutic topics related to the most common non-infectious systemic diseases associated with uveitis.

    1989-12-01

    A 62 year old male (R.H.) presented with a mild anemia (Hb 11-12 gm%) and a history of multiple hemorrhagic episodes. The marrow had 40-50% sideroblasts. Marrow chromosomes were normal. His wife was hematologically normal, while one daughter, age 30 years, had a sideroblastic anemia (Hb 11-12 gm%) with 40-50% sideroblasts in the marrow. Her anemia was first noted at age 15 years. Administration of vitamin B6 did not correct the anemia in either the father or daughter. Platelet abnormalities inherited jointly with this disorder are described for the first time. Both R.H. and his daughter had prolonged bleeding times, with normal PTT, PT times, fVIII:C, fVIII:Ag levels, and vWF multimers, which may rule out a von Willebrand's disease. They have normal platelet numbers but abnormally low platelet adhesiveness and greatly depressed ADP, collagen, and epinephrine responsiveness. Response to ristocetin was in the low normal range, and aggregation with thrombin was normal. While desmopressin completely normalized R.H.'s bleeding time, none of these platelet parameters were improved. No differences in the SDS PAGE protein patterns of RH platelets could be detected in comparison to normal samples. His platelets took up and released serotonin (5HT) normally, and electron micrographs defined no morphological abnormalities. However, no ATP was released from platelets activated with collagen, and when followed by thrombin about fourfold greater ATP was released by control platelets as compared to RH platelets. The dense granule fraction derived from RH platelets contained about 20% the level of ATP, 40% the level of ADP, and 50% the level of 5HT detected in a normal sample. The results indicate that the bleeding disorder is related to a non-classical heritable storage pool defect. The connection between the inherited sideroblastic anemia and platelet defects is obscure.

    Full Text Available Las recientes publicaciones científicas respecto de enfermedades infecciosas emergentes en especies silvestres están aumentando la preocupación internacional en el deterioro de la salud del ecosistema de los océanos, ambientes terrestres y límnicos. Se estudiaron investigaciones publicadas en los últimos 25 años. Los objetivos de este estudio fueron: 1 determinar la importancia del hábitat y la introducción de especies alóctonas, dentro del contexto de la contaminación y el cambio climático, en el surgimiento de enfermedades infecciosas, y 2 evaluar el riesgo de extinción de especies con problemas de conservación. La evaluación de los casos escogidos, más importantes, permite concluir que los patógenos responsables de las enfermedades infecciosas en especies silvestres pueden transmitirse rápidamente entre huéspedes pudiendo llegar a producir en corto tiempo epizootias que pueden poner en peligro poblaciones vulnerables en declinación. La destrucción del hábitat y la introducción de especies alóctonas son variables ambientales que significativamente afectan la ecología de las enfermedades infecciosas emergentes.

Hypothyroidism can cause a wide variety of anemic disorders. Numerous mechanisms are involved in the pathogenesis of these anemias that can be microcytic, macrocytic and normocytic. We designed this study to investigate the anemia frequency and if present, etiology of anemia in hypothyroid patients. 100 patients with overt hypothyroid, 100 patients with subclinical hypothyroid, and 200 healthy controls were enrolled in this study. Overt hypothyroidism diagnosis is done when elevated TSH and low levels of free T4 and/or free T3 have been observed. Subclinical hypothyroidism is defined as elevated serum TSH with normal free T(4) and free T(3) levels. Peripheral smears of the anemic patients were examined. Anemia prevalence was 43% in the overt hypothyroid group, 39% in the subclinical hypothyroid group, and 26% in the control group (p=0.0003 and p=0.021 respectively related to controls). Thus, the frequency of anemia in subclinical hypothyroidism is as high as that in overt hypothyroidism. There was no difference between the hypothyroid groups in terms of anemia. Vitamin B12, Fe, and folic acid were similar between these groups. According to our findings, anemia of chronic disease is the most common type of anemia in hypothyroid patients. Suspicion of hypothyroidism should be considered in anemias with uncertain etiology.

    Full Text Available In many elderly patients with anemia, a specific cause cannot be identified. This study investigates whether erythropoietin levels are inappropriately low in these cases of "anemia of unknown etiology" and whether this trend persists after accounting for confounders.This study includes all anemic patients over 60 years old who had erythropoietin measured between 2005 and 2013 at a single center. Three independent reviewers used defined criteria to assign each patient's anemia to one of ten etiologies: chronic kidney disease, iron deficiency, chronic disease, confirmed myelodysplastic syndrome (MDS, suspected MDS, vitamin B12 deficiency, folate deficiency, anemia of unknown etiology, other etiology, or multifactorial etiology. Iron deficiency anemia served as the comparison group in all analyses. We used linear regression to model the relationship between erythropoietin and the presence of each etiology, sequentially adding terms to the model to account for the hemoglobin concentration, estimated glomerular filtration rate (eGFR and Charlson Comorbidity Index.A total of 570 patients met the inclusion criteria. Linear regression analysis showed that erythropoietin levels in chronic kidney disease, anemia of chronic disease and anemia of unknown etiology were lower by 48%, 46% and 27%, respectively, compared to iron deficiency anemia even after adjusting for hemoglobin, eGFR and comorbidities.We have shown that erythropoietin levels are inappropriately low in anemia of unknown etiology, even after adjusting for confounders. This suggests that decreased erythropoietin production may play a key role in the pathogenesis of anemia of unknown etiology.

    Cancer related anemia (CRA) adversely affects patient Quality of Life (QoL) and overall survival. We prospectively studied the prevalence, etiology and the impact of anemia on QoL in 218 Indian cancer patients attending a tertiary referral hospital. The study used the sTfR/log Ferritin index to detect iron deficiency anemia and assessed patient QoL using the Functional Assessment of Cancer Therapy-Anemia (FACT-An) tool, standardized for language. Mean patient age was 51±13 years and 60% were female. The prevalence of cancer related anemia in this setting was 64% (n = 139). As expected, plasma ferritin did not differ significantly between anemic (n = 121) and non-anemic cancer patients (n = 73). In contrast, plasma sTfR levels were significantly higher in anemic cancer patients compared to non-anemic cancer patients (31 nmol/L vs. 24 nmol/L, p = 0.002). Among anemic cancer patients, using the sTfR/log Ferritin index, we found that 60% (n = 83) had iron deficiency anemia (IDA). Interestingly, plasma sTfR levels were significantly higher in cancer patients with CRA+IDA (n = 83) compared with patients having CRA (n = 38) alone (39 nmol/L vs. 20 nmol/L, p<0.001). There was a significant linear correlation between Hb and QoL (Spearman ρ = 0.21; p = 0.001) and multivariate regression analysis revealed that every gram rise in Hb was accompanied by a 3.1 unit increase in the QoL score (95% CI = 0.19–5.33; p = 0.003). The high prevalence of anemia in cancer patients, a major portion of which is due to iron deficiency anemia, the availability of sensitive and specific biomarkers of iron status to detect IDA superimposed on anemia of inflammation, suggests an urgent need to diagnose and treat such patients. Despite the potential negative consequences of increasing metabolically available plasma iron in cancer, our clinical data suggest that detecting and treating IDA in anemic cancer patients will have important consequences to their QoL and overall survival.

    Full Text Available Este trabalho descreve o estabelecimento de um pro!tocolo de "nested-PCR" para a detecção do vírus da anemia das galinhas (CAV, chicken anemia virus, agente causador da anemia infecciosa das galinhas. Para a extração de DNA a partir de amostras clínicas um método baseado no uso de tiocianato de guanidina mostrou-se mais sensível e prático, do que os demais avaliados. Para a PCR inicial foi selecionado um par de primers que amplifica uma região de 664 pares de bases (pb do gene VP1. Para a "nested-PCR" propriamente dita, foi selecionado um segundo par que amplifica uma região interna de 520 pb. A especificidade dos primers foi avaliada utilizando amostras de lotes controlados para CAV. Outras trinta amostras vírus e bactérias, causadoras de doenças em aves, não geraram produto de amplificação. A sensibilidade do teste foi determinada a partir de diluições seriadas de uma amostra vacinal de CAV. A "nested-PCR" mostrou ser mais sensível do que a PCR e foi capaz de detectar pelo menos 0,16 TCID50% da cepa vacinal. Além disso, detectou DNA viral em tecidos, soro e cama aviária de lotes com e sem sinais clínicos. Conclui-se que, como técnica para a detecção do CAV, o protocolo de "nested-PCR" aqui descrito, é mais sensível, rápido e menos trabalhoso do que o isolamento viral em cultivo celular.This paper reports a nested polymerase chain reaction (nested-PCR protocol for detection of chicken anemia virus (CAV, the causal agent of infectious chicken anemia.

    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.

    Full Text Available James W Swann,1 Barbara J Skelly2 1Queen Mother Hospital for Animals, The Royal Veterinary College, Hatfield, Hertfordshire, 2Department of Veterinary Medicine, University of Cambridge, Cambridge, UK Abstract: Immune-mediated hemolytic anemia is one of the most common manifestations of canine immune-mediated disease, yet treatment regimens remain nonstandardized and, in some cases, controversial. The main reason for this, as for most diseases in veterinary medicine, is the lack of large-scale placebo-controlled trials so that the efficacy of one treatment over another can be established. Most of the evidence used for treatment comes from retrospective studies and from personal preference and experience, and because of this, treatment regimens tend to vary among institutions and individual clinicians. Management of immune-mediated hemolytic anemia includes immunosuppression, thromboprophylaxis, and supportive care measures to help prevent and treat concurrent conditions.

  7. Iron deficiency decreases hemolysis in sickle cell anemia Anemia ferropriva diminui hemólise em anemia falciforme

    Full Text Available A woman with homozygous sickle cell disease developed severe iron deficiency due to long-standing uterine bleeding. At this point, the serum lactic dehydrogenase level was normal and the reticulocyte count was only minimally elevated. This suggested that the low red cell hemoglobin concentration that resulted from iron deficiency also decreased Hb S polymerization and lowered the hemolytic rate. Iron replacement led first to a substantially improved hemoglobin concentration with only a minimal increase in the hemolytic rate and secondarily to a modest further improvement in the hemoglobin concentration and a marked increase in the hemolytic rate. The hematologic changes observed in this patient, and those in other iron deficient sickle cell patients reported in the literature, suggest that it may be appropriate to consider the induction of an intermediate iron deficient stage as experimental treatment in adult sickle cell patients.Uma mulher com anemia falciforme homozigose para a Hb S evoluiu com anemia ferropriva grave devido a sangramento uterino prolongado. A dosagem de dehidrogenase lática era normal e a contagem de reticulócitos estava levemente aumentada. Isto sugere que concentrações baixas de hemoglobina, que resulta de anemia ferropriva, também diminuem a polimeração de Hb S e reduz a taxa de hemólise. O complemento de ferro levou, primeiramente, a uma concentração substancialmente maior de hemoglobina com apenas um aumento mínimo na taxa hemolítica e subsequentemente a um aumento leve adicional na concentração da hemoglobina e um aumento notável na taxa hemolítica. As mudanças hematológicas observadas nesta paciente e aquelas em outras pacientes com anemia falciforme e também deficientes de ferro relatadas na literatura sugerem que pode ser interessante considerar a indução de deficiência de ferro como tratamento experimental em pacientes adultos com anemia falciforme.

    Background In Korea, the prevalence of anemia and iron deficiency anemia (IDA) among older infants and young children remains high. To detect IDA early and to reduce its adverse impact, we assessed the characteristics of infants and young children who had IDA or were at risk of developing IDA, or who exhibited characteristics associated with severe anemia. Methods Among the 1,782 IDA-affected children aged 6 months to 18 years who visited the hospital, we retrospectively analyzed the medical records and laboratory data of 1,330 IDA-affected children aged 6–23 months who were diagnosed between 1996 and 2013. We excluded patients with a C-reactive protein level ≥5 mg/dL. Results IDA was predominant in boys (2.14:1) during infancy and early childhood. The peak IDA incidence was noted among infants aged 9–12 months. Only 7% patients exhibited symptoms of IDA, while 23.6% patients with severe IDA demonstrated classic symptoms/signs of IDA. Low birth weight (LBW) infants with IDA demonstrated low adherence to iron supplementation. In a multivariate analysis, prolonged breastfeeding without iron fortification (odds ratio [OR] 5.70), and a LBW (OR 6.49) were identified as risk factors of severe anemia. Conclusion LBW infants need more attention in order to increase their adherence to iron supplementation. For the early detection of IDA, nutritional status of all infants, and iron batteries of high-risk infants (LBW infants, infants with prolonged breastfeeding, picky eaters, and/or infants with the presence of IDA symptoms) should be evaluated at their health screening visits.

    2006-02-01

    Full Text Available Los péptidos antimicrobianos son moléculas efectoras clave en la inmunidad innata. Generalmente contienen de 15 a 45 residuos de aminoácidos y en su gran mayoría poseen carga positiva, además de que tienen la propiedad de ser anfipáticos. Estos péptidos son secretados por células epiteliales y leucocitos, como es el caso de los macrófagos y neutrófilos. En la actualidad, con base en la traducción de secuencias en programas computacionales se han descrito más de 800 tipos de péptidos antimicrobianos distribuidos en los reinos animal y vegetal. Estos péptidos pueden ser clasificados de acuerdo con su conformación estructural y la ubicación de sus puentes disulfuro. Las defensinas constituyen uno de los tipos de péptidos antimicrobianos más estudiados, y se dividen en dos familias de acuerdo con la ubicación de sus puentes disulfuro: alfa-defensinas y beta-defensinas. Algunas de estas defensinas pueden ser inducidas por citocinas proinflamatorias, así como por moléculas propias de patógenos, y se ha observado que están relacionadas con la inmunopatogenia de varias enfermedades. El papel principal de los péptidos antimicrobianos es la lisis directa de microorganismos; sin embargo, a la fecha también se han descrito propiedades quimiotácticas, que le permiten modular el sistema inmune y de esta forma constituir un puente entre la inmunidad innata y la inmunidad adaptativa. Actualmente se han iniciado estudios con la posibilidad de utilizar esta clase de moléculas como nuevos fármacos en diferentes tipos de enfermedades infecciosas.Antimicrobial peptides are key effector molecules of the innate immune response. Generally, they are formed by 14-45 aminoacid residues; most of them have a positive charge and amphipathic properties.

    Anemia represents a substantial problem for children living in areas with limited resources and significant parasite burden. We performed a cross-sectional study of 254 Kenyan preschool- and early school-age children in a setting endemic for multiple chronic parasitic infections to explore mechanisms of their anemia. Complete venous blood cell counts revealed a high prevalence of local childhood anemia (79%). Evaluating the potential links between low hemoglobin and socioeconomic factors, nutritional status, hemoglobinopathy, and/or parasite infection, we identified age anemia. A total of 130/155 (84%) of anemic children with iron studies had evidence of iron-deficiency anemia (IDA), 16% had non-IDA; 50/52 of additionally tested anemic children met soluble transferrin-receptor (sTfR) criteria for combined anemia of inflammation (AI) with IDA. Children in the youngest age group had the greatest odds of iron deficiency (OR: 10.0, 95% CI: 3.9, 26). Although older children aged 9-11 years had less anemia, they had more detectable malaria, Schistosoma infection, hookworm, and proportionately more non-IDA. Anemia in this setting appears multifactorial such that chronic inflammation and iron deficiency need to be addressed together as part of integrated management of childhood anemia.

    Anemia, the most common hematologic abnormality, is a reduction in the concentration of erythrocytes or hemoglobin in blood. The two most common causes of anemia in pregnancy and the puerperium are iron deficiency and acute blood loss. Iron requirements increase during pregnancy, and a failure to maintain sufficient levels of iron may result in adverse maternal-fetal consequences. The purpose of this document is to provide a brief overview of the causes of anemia in pregnancy, review iron requirements, and provide recommendations for screening and clinical management of anemia during pregnancy.

    Occupational lead exposure can cause anemia at blood lead levels >50 microg/dl, as high as rarely occurs in industrialized countries nowadays. Whereas other forms of anemia are fairly probable to be found in lead exposed workers, especially in areas highly endemicfor extraoccupational anemias, such as beta thalassemia and iron deficiency anemia. The etiology of anemias has to be correctly defined in order to assess suitable therapeutical approaches and medicolegal consequences. The objective of this study is to verify in male lead exposed workers whether an accurate evaluation of hemocromocytometric parameters and of usual biological indices of lead exposure and effect on heme can differentiate the most common forms of anemia in Southern Italy. 68 workers occupationally exposed to low to moderate lead doses were studied and 59 workers of an alimentary plant have been taken as control group. On venous blood samples collected from these workers a complete hemocromocytometric test was performed and blood lead and erythrocytic zincoprotoporphyrin were determined. Anemia (Hb lead exposed workers and in a nonexposed worker. The reasoned evaluation of laboratory parameters led to identify among lead exposed workers four subjects with high probability of beta-thalassemic trait and two with lead poisoning anemia. Moreover a diagnostic algorithm was developed based on literature that seems to be able to discriminate lead poisoning from other causes of anemia in lead exposed workers in this study.

    Lead pollution is a substantial problem in developing countries such as India. The US Centers for Disease Control and Prevention has defined an elevated blood lead level in children as > or = 10 microg/dl, on the basis of neurologic toxicity. The US Environmental Protection Agency suggests a threshold lead level of 20-40 microg/dl for risk of childhood anemia, but there is little information relating lead levels anemia. Therefore, the authors examined the association between lead levels as low as 10 mug/dl and anemia in Indian children under 3 years of age. Anemia was divided into categories of mild (hemoglobin level 10-10.9 g/dl), moderate (hemoglobin level 8-9.9 g/dl), and severe (hemoglobin level Lead levels lead levels > or = 10-19.9 microg/dl and 97 (9%) had levels > or = 20 microg/dl. After adjustment for child's age, duration of breastfeeding, standard of living, parent's education, father's occupation, maternal anemia, and number of children in the immediate family, children with lead levels > or = 10 microg/dl were 1.3 (95% confidence interval: 1.0, 1.7) times as likely to have moderate anemia as children with lead levels anemia was 1.7 (95% confidence interval: 1.1, 2.6). Health agencies in India should note the association of elevated blood lead levels with anemia and make further efforts to curb lead pollution and childhood anemia.

    Despite its high prevalence, anemia often does not receive proper clinical attention, and detection, evaluation, and management of iron deficiency anemia and iron-restricted erythropoiesis can possibly be an unmet medical need. A multidisciplinary panel of clinicians with expertise in anemia management convened and reviewed recent published data on prevalence, etiology, and health implications of anemia as well as current therapeutic options and available guidelines on management of anemia across various patient populations and made recommendations on the detection, diagnostic approach, and management of anemia. The available evidence confirms that the prevalence of anemia is high across all populations, especially in hospitalized patients. Anemia is associated with worse clinical outcomes including longer length of hospital stay, diminished quality of life, and increased risk of morbidity and mortality, and it is a modifiable risk factor of allogeneic blood transfusion with its own inherent risks. Iron deficiency is usually present in anemic patients. An algorithm for detection and management of anemia was discussed, which incorporated iron study (with primary emphasis on transferrin saturation), serum creatinine and glomerular filtration rate, and vitamin B12 and folic acid measurements. Management strategies included iron therapy (oral or intravenous), erythropoiesis-stimulating agents, and referral as needed.

    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 Sanemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    Full Text Available En este artículo se analizan dos facetas importantes de las enfermedades infecciosas emergentes. Por un lado, las características de los microorganismos que las causan, por otro, las características del ser humano que promueven o contribuyen al surgimiento de las enfermedades infecciosas. Desde el punto de vista microbiano, se pueden identificar tres aspectos fundamentales. Primero, los patógenos emergentes son predominantemente virales, seguidos por los bacterianos. Numéricamente los virus ARN dominan, constituyendo el 37% de todos los patógenos emergentes. Los virus ARN predominan entre los virus patógenos emergentes que aparentemente entraron en las poblaciones humanas en las últimas décadas, como VIH y el coronavirus asociado al SARS. Segundo, los patógenos emergentes no se asocian a un único tipo de hospedero, sino que usualmente tienen amplio rango de hospederos que incluye varios órdenes de especies de mamíferos y no mamíferos. En efecto, la mayoría de las infecciones emergentes son de origen zoonótico. Tercero, los patógenos emergentes tienen un cierto grado de flexibilidad biológica que les permite aprovecharse de nuevas oportunidades epidemiológicas para ingresar a las poblaciones humanas. Las enfermedades infecciosas no son un problema reciente sino que han estado "emergiendo" a lo largo de la historia de la humanidad y es posible identificar, al menos, cuatro transiciones históricas. La última de esas transiciones es la globalización actual. Muchos factores antropogénicos inciden en el surgimiento de las enfermedades infecciosas emergentes, incluyendo eventos sociales, comportamiento humano, cambios ambientales, políticas en salud pública, procedimientos médicos y otros.In this review, 2 relevant aspects of emerging infectious diseases are analyzed: the characteristics of the microorganisms causing such infections and the human facts that promote or contribute to emerging infectious diseases.

Los hallazgos de necropsia más llamativos fueron la gran cantidad de líquido en cavidades torácica y peritoneal, áreas de necrosis coagulativa en el parénquima hepático y la abundante cantidad de Thysanosoma actinioides en canalículos biliares y colédoco. En improntas de hígado se identificó Clostridium novyi mediante inmunofluorescencia. De este mismo órgano se aisló posteriormente Clostridium novyi tipo B. Ante la falta del predisponente más comúnmente citado, Fasciola hepatica, se postula que el severo parasitismo por Thysanosoma actinioides fue el factor desencadenante de este brote de hepatitis infecciosa necrosanteAn outbreak of Black disease in Argentinean Patagonia where 80 sheep out of 1200 Merino ewes suddenly died, is reported. Big amounts of fluid in the thoracic and abdominal cavities, the presence of focal coagulative necrosis in the liver parenchyma and plenty Thysanosoma actinioides specimens in bile ducts were the most important findings observed at necropsy. Clostridium novyi was early detected in liver smears through immunofluorescence. Later, Clostridium novyi type B was isolated from liver cultures. Due to the absence of the commonest predisposing agent, i.e. Fasciola hepatica, the severe parasitism by Thysanosoma actinioides is proposed as the predisposing factor of the present outbreak of Black disease

    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 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 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.

    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.

    Ghinea, Mihaela Maria

    2004-01-01

    Iron deficiency anemia is a hypochromic anemia in which hemoglobin poor synthesis is due to a decrease in the amount of iron in the body. The decrease of iron quantity has many causes: insufficient intake of aliments rich in iron (meat, viscera, green vegetables), increased necessities during growth period, pregnancy, erythrocytes hyperregeneration, high-performance sportsmen, increased loss by digestive way, genito-urinary way, respiratory, hemorrhagic syndromes. Clinically, symptoms and signs specific to all types of anemia and those specific to lack of iron occur besides the symptoms and signs of the underlying disease: atrophic glositis, angular stomatitis, sideropenic dysphagia, pica, skin and nails changes. Laboratory investigations useful for diagnosis are: microcytic, hypochromic anemia, decreased serum iron level, total capacity of iron binding increased, medullar iron store absent, good response to iron therapy. Ferro-Folgamma is one of the most indicated medicines in iron deficiency anemia. Due to its components this medicine has many indications: insufficient alimentary intake concerning iron, folic acid, B12 vitamin, vegetarian alimentation, increased needs during growth period, iron deficiency anaemia secondary to chronic hemorrhages, malnutrition, anemias associated with chronic alcohol intake, preventive treatment of iron deficiency anemia and megaloblastic anemia during pregnancy and lactation.

    Isabela Martins Benseñor

    Full Text Available CONTEXT AND OBJECTIVES: Quantification of clinical signs such as the presence or absence of pallor at clinical examination is a key step for making diagnoses. The aim was, firstly, to evaluate two methods for anemia diagnosis by physical examination: four-level evaluation (crosses method: +/++/+++/++++ and estimated hemoglobin values, both performed by medical students and staff physicians; and secondly, to investigate whether there was any improvement in assessment accuracy according to the number of years in clinical practice. DESIGN AND SETTING: Forty-four randomly selected physicians and medical students in a tertiary care teaching hospital completed a physical examination on five patients with mild to severe anemia. METHODS: The observers used four-level evaluation and also predicted the hemoglobin level. Both methods were compared with the real hemoglobin value as the gold standard. RESULTS: The mean estimated hemoglobin value correlated better with the real hemoglobin values than did the four-level evaluation method, for attending physicians, residents and students (Spearman's correlation coefficients, respectively: 1.0, 1.0 and 0.9 for guessed hemoglobin and -0.8, -0.8 and -0.7 for the four-level evaluation method. There were no differences in the mean "guessed" hemoglobin values from attending physicians, residents and students. However, the correlation between guessed hemoglobin value and the four-level method was positive for attending physicians, thus suggesting some kind of improvement with time (p = 0.04. CONCLUSIONS: This study showed that estimated hemoglobin was more accurate than evaluation by the four-level method. The number of years in clinical practice did not improve the accuracy of clinical examination for anemia.

  8. Iron, anemia and hepcidin in malaria

    Directory of Open Access Journals (Sweden)

    Natasha eSpottiswoode

    2014-05-01

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

    2014-01-01

    Uncompensated autoantibody-mediated red blood cell (RBC) consumption is the hallmark of autoimmune hemolytic anemia (AIHA). Classification of AIHA is pathophysiologically based and divides AIHA into warm, mixed or cold-reactive subtypes. This thermal-based classification is based on the optimal autoantibody-RBC reactivity temperatures. AIHA is further subcategorized into idiopathic and secondary with the later being associated with a number of underlying infectious, neoplastic and autoimmune disorders. In most cases AIHA is confirmed by a positive direct antiglobulin test (DAT).

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

    Full Text Available Ravish Shah, Anil K AgarwalDivision of Nephrology, The Ohio State University, Columbus, Ohio, USAAbstract: Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.Keywords: anemia, heart failure, chronic kidney disease, elderly population

    In this study, a patient who was hospitalized with a severe anemia in the Internal Medicine Clinic of the Health Research and Application Hospital of Yüzüncü Yil University for one week is presented. The patient had fatigue, paleness and dizziness for one month and approximately 12 kg weight lost for four mounts previous to admission.. Severe iron deficiency anemia was diagnosed in the patient by laboratory analyses. Because there were no hematologic factors associated with severe anemia, the stool examination was also performed. In the Parasitology Laboratory, stool microscopy of the patient revealed numerous ova of hookworm. General condition of the patient well improved with anti-parasitic and anti-anemia treatment. It was concluded that patients with iron deficiency anemia diagnosed in health centers should be also examined for the intestinal parasitic diseases encountered rarely, and physicians should consider non-endemic parasitic diseases in their provinces.

    This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living) and IADL (instrumental activities of daily living). Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    Amole, B O; Clarkson, A B; Shear, H L

    1982-01-01

    The pathogenesis of anemia was studied in trypanosome-infected mice. A strain of Trypanosoma brucei, TREU 667, was used which first produces an acute phase marked by waves of parasitemia. Erythrocytes from infected animals were coated with immunoglobulin M during or just before the waves of anemia and parasitological crises. Erythrocytes from normal animals could be sensitized with "precrisis" sera presumably containing antigen and antibody. These data suggest that anemia during the acute phase is due to sensitization of erythrocytes with immunoglobulin M-antigen complexes. The anemia is partially compensated by a strong erythropoietic response. The acute phase is followed by a chronic phase marked by a constant high parasitemia and immunosuppression. The less marked anemia occurring during this latter phase is due to hemodilution and perhaps a low but significant immune response to the parasites, which causes continuing erythrocyte sensitization by immunoglobulin M-antigen complexes.

    2010-02-01

    Iron deficiency is the most common cause of anemia in pregnancy. Pregnant women with anemia are, in general, exclusively treated with iron supplementation. We observed that several pregnant women with anemia who were nonresponsive to iron supplementation also had vitamin B6 deficiency, and that anemia in these cases improved with the administration of vitamin B6. Our prospective study in healthy pregnant women showed that blood levels of iron, ferritin and vitamin B6, in particular, fell to the lower limit of the nonpregnant reference range by the third trimester. We conclude that it is important to take into account the deficiency of vitamin B6 besides iron in the evaluation of anemia during pregnancy.

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

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

    Thirty patients with a wide range of sore mouth that led to the diagnosis of iron deficiency in 12 patients, pernicious anemia in 8 patients, combined deficiency of iron and vitamin B12 in 2 patients, and anemia of chronic disease in 8 patients were investigated. The oral signs and symptoms included glossitis, glossodynia, angular cheilitis, recurrent oral ulcer, oral candidosis, diffuse erythematous mucositis, and pale oral mucosa. The values of hemoglobin in 30 patients varied from normal to severe life-threatening levels, but none had developed generalized symptoms sufficiently advanced to arouse suspicions of anemia before they visited the Oral Medicine Clinic. The aim of this paper is to describe a retrospective study of 30 patients with oral changes as the initial manifestation of nutritional deficiency or anemia of chronic diseases. Improved diagnosis and classification of anemia based on the mean and heterogeneity of red cell size will be discussed.

  4. Microfluidic approach of Sickled Cell Anemia

    2012-11-01

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

    An autopsy case of erythremia with sideroblastic tumor cell proliferation is described. A 60-year-old man was admitted to the hospital due to general fatigue and anorexia. Bone marrow aspiration revealed abnormalities in erythropoiesis (megaloblasts, 4%; sideroblasts, 84%; ring-formed, 39%, and PAS-positive, 5%). Therapy was directed to pulmonary tuberculosis. Anemia was not improved despite repeated whole blood and platelet transfusions. Serum iron and percentage saturation of the total iron-binding capacity rose during the course. Administration of vitamin B12, B6 or folic acid was inefffective. INAH was replaced by its derivative, IHMS, during the course, but the population of sideroblasts especially of ring-sideroblasts was invariably large (78%-100% and 39%-65% for total sideroblasts and ring-sideroblasts, respectively). He died with increasing abdominal pain and jaundice after three months' hospitalization. Main autopsy findings were: diffuse proliferation of atypical erythroblasts in the bone marrow, systemic lymph nodes, liver, spleen and kidneys. Most of the cells positively stained with iron. Tuberculosis of lungs with cavity formation. Discussion is focussed on the relationship between erythremia and sideroblastic anemia.

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

    This study was conducted to determine the optimum dose of supplemental iron for prophylaxis against pregnancy anemia. One hundred and ten pregnant women were randomly allocated to three groups: Group A receiving equivalent of 60 mg, group B 120 mg and Group C 240 mg, elemental iron as ferrous sulphate daily; the content of folic acid was constant in all the three groups (0.5 mg). These women had at least consumed 90 tablets in 100 +/- 10 days. Blood was drawn at the beginning and at the end of the treatment. Fifty percent were anemic (less than 11 g/100 ml). The hemoglobin levels rose similarly in all groups and the differences were statistically not significant. Fifty-six percent had depleted iron stores (serum ferritin value less than 12 micrograms/l) at the beginning of the study. Following therapy a statistically significant increase in iron stores was observed in group B and C as compared to group A. The difference between group B and C was not significant. The side effects increased with increasing doses of iron; 32.4%, 40.3% and 72% in group A, B and C respectively. Based on these findings, the authors advocate that optimum dose of iron should be 120 mg instead of 60 mg as is currently being used in the National Nutritional Anemia Prophylaxis Programme.

    2013-01-01

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

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.

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

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

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

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

    2015-10-01

    Myelodysplastic syndromes (MDS) are a constellation of different diseases sharing anemia in the great majority of cases, and this cytopenia defines these pathologies and their most dramatic clinical manifestations. Anemia in MDS is due to ineffective erythropoiesis, with a high degree of apoptosis of marrow erythroid progenitors. These progenitors show distinctive dysplastic features that consent diagnosis, and are recognizable and differentiated, although not easily, from other morphologic alterations present in other types of anemia. Reaching the diagnosis of MDS in a macrocytic anemia and alleviating the symptoms of anemia are therefore an essential objective of the treating physician. In this work, the signs and symptoms of anemia in MDS, as well as its peculiar pathophysiology, are discussed. Erythopoietic stimulating agents (ESAs) are providing the best treatment for anemic MDS patients, but their use is still not approved by health agencies. While still waiting for this waiver, their clinical use is widespread and their effectivness is well known, as well as the dismal prognosis of patients who do not respond to ESAs and require transfusions. MDS with del5q constitute a unique model of anemia whose complex pathophysiology has been clarified at least partially, defining its link to ribosomal alterations likewise what observed in hereditary anemias like Blackfan Diamond anemia. Lenalidomide is the agent that has shown striking and specific erythropoietic activity in del5q MDS, and the basis of this response is starting to be understood. Several new agents are under evaluation for ESA refractory/relapsed MDS patients, targeting different putative mechanisms of ineffective erythropoiesis, and are here reviewed.

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

    Wang, Feng-Dan; Zhou, Dao-Bin

    2009-12-01

    Anemia of chronic disease is normocytic and normochromic. One of the mechanisms is misbalance of iron metabolism. Hepcidin, a kind of protein secreted by liver is considered to be the hormone regulating iron metabolism. It binds to ferroportin and induces the latter one's internalization. Thus, iron transportation from iron storage cells to serum is reduced. Cytokines are elevated in chronic disease. They stimulate hepcidin expression in liver through JAK2/STAT3 pathway. As a result, iron absorption and reabsorption is blocked, which leads to the misbalance of iron metabolism in anemia of chronic disease. In this article, the hepcidin and its relation to iron metabolism and anemia in chronic disease are reviewed.

    2006-11-01

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

    Labie, D

    1992-10-01

    The genetics of sickle cell anemia may be considered as a model. Its mendelian transmission was hypothesized even before the molecular era. Once the mutation identified, it could be studied at the protein and DNA level; a consistent pathophysiological mechanism was proposed; the various genetic forms of the disease could be identified; the way by which a balanced polymorphism with Plasmodium falciparum malaria is obtained was analyzed. More recently, investigations were run in order to understand how modulating, or epistatic factors could modify the pathophysiological mechanism and contribute to the high clinical diversity of the disease. Several factors have been identified, among which a concomitant alpha-thalassemia, an overproduction of fetal hemoglobin, due either to an activation of the gamma genes or to an increase of the F-cell number, and finally a quantitative control of the beta s chains themselves. Such a high number of genetic active factors questions the concept itself of a monogenic disease.

    The congenital dyserythropoietic anemias (CDAs) are a heterogeneous group of genetic disorders of red cell production. They are characterized by ineffective erythropoiesis and dyserythropoiesis. Here, we present the clinical description and mutation analysis of a Japanese female with CDA type 1. She has long been diagnosed with unclassified congenital hemolytic anemia from the neonatal period. However, bone marrow morphology and genetic testing of the CDAN1 gene at the age of 12 years confirmed the afore-mentioned diagnosis. Thus, we should be aware of the possibility of CDA if the etiology of congenital anemia or jaundice cannot be clearly elucidated.

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

    Introducción: la anemia gestacional todavía se considera un problema de salud pública en Brasil y se asocia con un mayor riesgo de morbilidad materno-fetal y el estado nutricional de los niños en el período posparto. Objetivo: evaluar la frecuencia de la anemia gestacional materna en recién nacidos y su relación con el estado nutricional del niño al nacer. Métodos: se obtuvieron datos antropométricos de las mujeres embarazadas y los recién nacidos. Se recogieron muestras de sangre de mujeres embarazadas y de cordón umbilical de los recién nacidos para su posterior análisis de hemoglobina, hematocrito, ADE, hierro, ferritina e índice de saturación de transferrina en dispositivos automatizados. Los resultados se presentan como media y la desviación estándar. Fue utilizado el software GraphPadinStat®, versión 3.0 y se aceptó un nivel de significación del 5%. Resultados: la frecuencia de anemia materna era de 53,7% y 32,6% en los recién nacidos. La mitad de los recién nacidos eran niños anémicos de madres anémicas. De las mujeres embarazadas con anemia, el 79,3% tenían anemia leve y el 20,7% moderada. La concentración media de hemoglobina y hematocrito fue menor en las mujeres embarazadas con anemia (9,7 ± 0,9 g/ dl y 29,8 ± 3,2%) en comparación con las no anémicas (11,9 ± 0,7 g/dl y 36,5 ± 2,7%), como se esperaba. El nivel de hierro de la madre se correlacionó positivamente con ferritina (r = 0,389; p = 0,01) a partir de la sangre del cordón umbilical.

    Shah, Ravish; Agarwal, Anil K

    2013-01-01

    Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.

MAIN MEASUREMENTS: GDM patients either newly diagnosed or on follow up were selected and complete blood counts including the peripheral smear, blood sugar levels and HbA1c were done. RESULTS: Anemia was diagnosed in 6 patients (6% who are considerably less compared to Non-GDM pregnancy (40-50%. Out of which only 1 patient’s peripheral smear showed Microcytic hypochromic blood picture whereas rest showed Normocytic Normochromic picture. CONCLUSION: Our study suggests that incidence of Anemia especially Microcytic Hypochromic Anemia is considerably lower in GDM. These finding suggests that routine supplementation of Iron irrespective of Hemoglobin (Hb levels should be reconsidered in risk group women.

    Sex chromosome aneuploidies range in incidence from rather common to exceedingly rare and have a variable phenotype. We report 2 patients with sex chromosome aneuploidies who developed severe aplastic anemia requiring treatment. The first patient had tetrasomy X (48,XXXX) and presented at 9 years of age, and the second patient had trisomy X (47,XXX) and presented at 5 years of age. Although aplastic anemia has been associated with other chromosomal abnormalities, sex chromosome abnormalities have not been traditionally considered a risk factor for this condition. A review of the literature reveals that at least one other patient with a sex chromosome aneuploidy (45,X) has suffered from aplastic anemia and that other autosomal chromosomal anomalies have been described. Despite the uncommon nature of each condition, it is possible that the apparent association is coincidental. A better understanding of the genetic causes of aplastic anemia remains important.

    Full Text Available Hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (AVR.The mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. It appears to be independent of its severity as assessed by echocardiography. We present a case of a 24-year-old man with a history of AVR in 10 year ago that developed severe hemolytic anemia due to a mild subvalvar stenosis caused by pannus formation and mild hypertrophic septum. After exclusion of other causes of hemolytic anemia and the lack of clinical and laboratory improvement, the patient underwent redo valve surgery with pannus and subvalvar hypertrophic septum resection. Anemia and heart failure symptoms gradually resolved after surgery

    The gastrointestinal (GI) tract is a common site of bleeding that may lead to iron deficiency anemia (IDA). Treatment of IDA depends on severity and acuity of patients’ signs and symptoms. While red blood cell transfusions may be required in hemodynamically unstable patients, transfusions should be avoided in chronically anemic patients due to their potential side effects and cost. Iron studies need to be performed after episodes of GI bleeding and stores need to be replenished before anemia develops. Oral ...

    Pernicious anemia (PA) is a macrocytic anemia that is caused by vitamin B12 deficiency, as a result of intrinsic factor deficiency. PA is associated with atrophic body gastritis (ABG), whose diagnosis is based on histological confirmation of gastric body atrophy. Serological markers that suggest oxyntic mucosa damage are increased fasting gastrin and decreased pepsinogen I. Without performing Schilling’s test, intrinsic factor deficiency may not be proven, and intrinsic factor and parietal ce...

    Full Text Available Anemia is a very common disorder both in clinical practice and in the community. The recent rise in the population of the elderly has become the focus of attention in developing countries, because of the increasing longevity of the elderly, whilst the prevalence of anemia increases with age. The objective of this study was to determine the prevalence of anemia and its association with the quality of life in the elderly. A cross-sectional study was conducted from April to June 2008, located in the Mampang Prapatan district, South Jakarta. A total of 298 elderly persons participated in this study, comprising 109 (36.6% males and 189 (63.4% females. Anemia was measured by the parameters of hemoglobin and quality of life was assessed by the WHOQOL-BREF instrument, a short version of the WHOQOL-100 instrument. The results of the study showed the prevalence of anemia to be 26.2%, with a higher prevalence rate in females compared with males. The quality of life in the physical, psychological, social and environmental domains differed significantly with decreasing hemoglobin levels, whereas the physical and mental quality of life declined significantly with age. Anemia is thus indicative of a reduction in the quality of life of the elderly.

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

    Patients surviving sepsis develop anemia but the molecular mechanism is unknown. Here we observed that mice surviving polymicrobial Gram-negative sepsis develop hypochromic, microcytic anemia with reticulocytosis. The bone marrow of sepsis survivors accumulates polychromatophilic and orthochromatic erythroblasts. Compensatory extramedullary erythropoiesis in the spleen is defective during terminal differentiation. Circulating TNF and IL-6 are elevated for five days after the onset of sepsis, and serum HMGB1 levels are increased from day seven until at least day 28. Administration of recombinant HMGB1 to healthy mice mediates anemia with extramedullary erythropoiesis and significantly elevated reticulocyte counts. Moreover, administration of anti-HMGB1 monoclonal antibodies after sepsis significantly ameliorates the development of anemia (hematocrit 48.5±9.0% versus 37.4±6.1%, p<0.01, hemoglobin 14.0±1.7g/dL versus 11.7±1.2g/dL, p<0.01). Together, these results indicate that HMGB1 mediates anemia by interfering with erythropoiesis, suggesting a potential therapeutic strategy for anemia in sepsis.

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

    Anemia is common among young women, and iron deficiency is one of the leading causes. In Europe and the US, the iron fortification of flour increased oral iron intake and decreased anemia prevalence from 30% to 10%. The National Nutrition Survey in Japan revealed that anemia prevalence among young Japanese women is increasing; however, no nationwide preventive policy has been aimed at iron deficiency anemia. The endpoint of this study was the estimation of anemia prevalence among healthy Japanese woman, based on a large sample size. We collected data from the consecutive check-up examination records of apparently healthy women (n = 13,147). We defined hemoglobin lower than 12 g/dL as anemia, hemoglobin lower than 10 g/dL as severe anemia, and a mean corpuscular volume lower than 80 fl as microcytic anemia. Of the 13,147 persons, anemia was identified in 2331 (17.3 %), and severe and microcytic anemia in 438 (3.3 %) and 700 (5.2 %), respectively. Among women younger than 50 years, anemia was identified in 22.3 %, and 25.2 % of them had severe anemia. In conclusion, the prevalence of anemia and severe anemia among young women is high in Japan. Some action needs to be considered to improve women's quality of life.

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 Iron deficiency anemia (IDA and anemia of chronic disease are the most commonly confused anemias. We investigate the diagnostic value of erythrocyte indices, red cell volume distribution width, and serum ferritin levels to make differential diagnosis of anemia in controls and anemic patients.Iron deficiency anemia (44 patients, anemia of chronic disease (41, IDA with anemia of chronic disease (17 and control (50 groups were compared. We performed serum ferritin, CBC, and sedimentation rate in all patientsand bone marrow aspiration in patients with anemia of chronic disease.Although mean cell volume (MCV and mean corpuscular hemoglobin (MCH are low in IDA and anemia of chronic disease, it is much striking in the former one (p<0.001, p<0.001. Only 7.3% of patients with anemia of chronic disease had a MCV<70 fL and MCH<24 pg, 90.0% of patients with IDA were below that cut-off point. Serum ferritin means were in patients with IDA and anemia of chronic disease were 4.6±3.3 and 489.6 ±519.9 ng/ml, respectively.The probability of IDA is low when RDW is normal in microcytic anemias. RDW is high in half of patients with anemia of chronic disease. Reference values for ferritin must be changed in patients with anemia of chronic disease and IDA. If serum ferritin is 57.6-146.4 ng/ml anemia of chronic disease and iron deficiency must ruled out by other diagnostic tests.

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

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

    Directory of Open Access Journals (Sweden)

    Clara Camaschella

    2013-03-01

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

    Full Text Available INTRODUCTION: Sickle cell anemia and thalassemia result in impaired bone health in both adults and youths. Children with other types of chronic hemolytic anemia may also display impaired bone health. STUDY DESIGN: To assess bone health in pediatric patients with chronic hemolytic anemia, a cross-sectional study was conducted involving 45 patients with different forms of hemolytic anemia (i.e., 17 homozygous sickle cell disease and 14 hereditary spherocytosis patients. Biochemical, radiographic and anamnestic parameters of bone health were assessed. RESULTS: Vitamin D deficiency with 25 OH-vitamin D serum levels below 20 ng/ml was a common finding (80.5% in this cohort. Bone pain was present in 31% of patients. Analysis of RANKL, osteoprotegerin (OPG and osteocalcin levels indicated an alteration in bone modeling with significantly elevated RANKL/OPG ratios (control: 0.08+0.07; patients: 0.26+0.2, P = 0.0007. Osteocalcin levels were found to be lower in patients compared with healthy controls (68.5+39.0 ng/ml vs. 118.0+36.6 ng/ml, P = 0.0001. Multiple stepwise regression analysis revealed a significant (P<0.025 influence of LDH (partial r2 = 0.29, diagnosis of hemolytic anemia (partial r2 = 0.05 and age (partial r2 = 0.03 on osteocalcin levels. Patients with homozygous sickle cell anemia were more frequently and more severely affected by impaired bone health than patients with hereditary spherocytosis. CONCLUSION: Bone health is impaired in pediatric patients with hemolytic anemia. In addition to endocrine alterations, an imbalance in the RANKL/OPG system and low levels of osteocalcin may contribute to this impairment.

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

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

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

    Recent advances in the treatment of aplastic anemia (AA) made most of patients to expect to achieve a long-term survival. Allogeneic stem cell transplantation (SCT) from HLA-matched sibling donor (MSD-SCT) is a preferred first-line treatment option for younger patients with severe or very severe AA, whereas immunosuppressive treatment (IST) is an alternative option for others. Horse anti-thymocyte globuline (ATG) with cyclosporin A (CsA) had been a standard IST regimen with acceptable response rate. Recently, horse ATG had been not available and replaced with rabbit ATG in most countries. Subsequently, recent comparative studies showed that the outcomes of patients who received rabbit ATG/CsA were similar or inferior compared to those who received horse ATG/CsA. Therefore, further studies to improve the outcomes of IST, including additional eltrombopag, are necessary. On the other hand, the upper age limit of patients who are able to receive MSD-SCT as first-line treatment is a current issue because of favorable outcomes of MSD-SCT of older patients using fludarabine-based conditioning. In addition, further studies to improve the outcomes of patients who receive allogeneic SCT from alternative donors are needed. In this review, current issues and the newly emerging trends that may improve their outcomes in near futures will be discussed focusing the management of patients with AA.

    Full Text Available Autoimmune hemolytic anemia (AIHA is a rare disease with an estimated prevalence of around 17/100,000. It is often difficult to diagnose and treat AIHA, especially in elderly. A 60-year-old female was admitted with the complaints of low grade fever, on-off for 6 months, progressive fatigue and dyspnea on exertion. She was transfused with three units of blood within these 6 months. Examination revealed pallor, edema, hemic murmur, and palpable liver. Hb was 2.9 gm%, T Bil 5.2 mg/dl, ESR 160 mm, and reticulocyte count 44.05%. Direct Coombs test was positive, anti-nuclear antibody (ANA and Anti ds DNA were positive. A diagnosis of systemic lupus erythematosus (SLE with AIHA was considered and patient was transfused with two units of packed red cells and put on steroid (prednisolone at 1 mg/kg body weight daily. After 3 weeks, her Hb had increased to 10.4 gm% with gross clinical improvement.

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

Esta patología es poco común y poco documentada cuando afecta la articulación temporomandibular, existiendo sólo reporte de casos. Por lo anterior, muchas veces pasa desapercibida por distintos profesionales del área de la salud. El diagnóstico de la AI mediante radiología no aporta gran información en etapas tempranas de la patología (Lavy, 2007; Visser & Tupper, 2009. Un método de diagnóstico utilizado en grandes articulaciones del cuerpo es el cultivo de líquido sinovial (Lavy; Visser & Tupper, examen complejo de realizar en la articulación temporomandibular dado su tamaño y pequeña cantidad de fluido sinovial, siendo así el diagnóstico de AI en gran medida clínico, y en el caso de la articulación temporomandibular es aún más importante la experticia y conocimientos del clínico. El tratamiento se debe basar en la eliminación del agente causal mediante farmacoterapia orientada a la eliminación de éste (Lavy; Visser & Tupper. La artritis infecciosa por sus características de avance rápido, agresivo y degenerativo, debe ser considerada como un posible diagnóstico en la articulación temporomandibular, por lo que esta revisión bibliográfica presenta información acabada sobre la epidemiología, etiopatogenia, diagnóstico y tratamiento de dicha patología existente en diversas bases de datos y literatura contemporánea.Infectious arthritis (IA is, as its name implies, infection of a joint in the body caused by an agent that can be bacterial, viral or fungal (Bluestone, 1980, Garcia & Picazo, 1996.

El cólera es una en fermedad infecciosa reemergente , caracterizada por diarreas profusas, con apariencia de agua de arroz, causada por la ingestión de alimentos o agua s contaminada s con la bacteria Vibrio cholerae de los serogrupos O1 y O139. El serogrupo O1 es el causante de la séptima pandemia. La incidencia de diversos factores como son los desastres naturales, sistemas sanitarios deficientes, la poca accesibilidad al agua potable, ha favorecido a que cada año se reporte n entre 3 y 5 millones de personas que sufren esta enfermedad, con una alta cif ra de defunciones . Además, en muchas regiones del planeta, el cólera se ha vuelto endémico, lo que ha provocado grandes pérdidas en la macro y microeconomía de los países afectados. Asimismo, se ha reportado un aumento de la resistencia a los agentes antim icrobian os usados tradi cionalmente para combatir la enf ermedad. Por tal razón, desde el año 2005 la Organización Mundial de la Salud ha recomendado el uso de vacunas orales como una herramienta para el control de la enfermedad en ciertas situaciones endémicas y epidémicas.

    Full Text Available Usualmente exhortamos a los estudiantes que no malgasten los antibióticos por que cada día la situación es casi apocalíptica para el tratamiento de patologías infecciosas. Para motivarlos, les explicamos que desde tiempos memorables se conocen historias como las de las momias egipcias que presentaron lesiones compatibles con tuberculosis, hermosas cortesanas del renacimiento con sífilis y momias precolombinas con lepra. La colonización de las Américas por parte de los anglosajones, españoles y portugueses en los siglos XIV y XV fue el inicio de la globalización y de la importación sin aranceles de nuevos microbios. Hoy día el transporte moderno es más eficaz, el turismo, los negocios y la inmigración se incrementaron, y las guerras internas y externas han desplazado millones de personas como sucede en Colombia. También la tecnología ha contribuido a mejorar la movilidad de los gérmenes, por ejemplo en 24 horas puede viajar el virus del Ébola o una tuberculosis multirresistente en un avión desde África a las Américas. La diseminación no es nueva, sólo que ahora se posee un mejor diagnóstico a través de la biología molecular y otras técnicas serológicas modernas.

    Full Text Available El virus de bronquitis infecciosa (IBV causa una enfermedad altamente contagiosa, distribuida mundialmente, que conlleva graves pérdidas económicas. En algunas oportunidades se asocia con otras entidades como los virus de las enfermedades de Gumboro y de Newcastle, Mycoplasma gallisepticum y Escherichia coli. La alta variabilidad genética del virus ha generado una gran cantidad de cepas virales con diferentes cuadros clínicos. El objetivo del trabajo fue evaluar la dinámica de anticuerpos del IBV en aves vacunadas y no vacunadas contra IBV, alojadas en una explotación de pollo de engorde donde se detectó el agente por RT-PCR, en Fusagasugá, Colombia, y aves vacunadas en semiaislamiento en Bogotá. Para esto se organizaron 3 grupos de aves (Ross 308 de 1 día de edad (44 aves/grupo, las cuales fueron vacunadas con un virus vivo atenuado, cepa Massachusetts H120, y se evaluó la respuesta inmune a través de la prueba de Elisa. Desde el primer día hasta el día 24 de edad se observó una disminución progresiva de los títulos de anticuerpos en los tres grupos, aunque en las aves vacunadas y no vacunadas mantenidas en granja se observaron niveles de anticuerpos superiores al grupo en condiciones de semiaislamiento. A partir del día 28 en las aves alojadas en campo se incrementaron levemente los títulos hasta final de ciclo. El leve aumento en el nivel de anticuerpos puede ser consecuencia de exposición al virus vacunal que generó reversión de patogenicidad, persistencia viral o una exposición tardía al virus de campo.

    Progress is reported on studies on hereditary anemias of mice. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, each of 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.

    Full Text Available This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living and IADL (instrumental activities of daily living. Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    Full Text Available Abstract Background HIV-associated anemia is common and associated with poor prognosis. However, its response to antiretroviral treatment (ART in rural Africa is poorly understood. Methods HIV-infected adults (≥15 years who enrolled in HIV care at Haydom Lutheran Hospital in northern Tanzania were included in the study. The effect of ART (zidovudine/stavudine + lamivudine + efavirenz/nevirapine on HIV-associated anemia was studied in a subset of patients who were anemic at the time they started ART and had a follow-up hemoglobin measurement 12 months later. Pregnant women were excluded from the study, as were women who had given birth within the past 6 weeks. Anemia was defined as hemoglobin Results At enrollment, mean hemoglobin was 10.3 g/dL, and 649 of 838 patients (77.4% were anemic. Of the anemic patients, 254 (39.1% had microcytosis and hypochromia. Among 102 patients who were anemic at ART initiation and had a follow-up hemoglobin measurement after 12 months, the mean hemoglobin increased by 2.5 g/dL (P Conclusions Most patients had anemia at enrollment, of whom nearly 40% had microcytosis and hypochromia suggestive of iron deficiency. The mean hemoglobin increased significantly in patients who received ART, but one third were still anemic 12 months after ART initiation indicating that additional interventions to treat HIV-associated anemia in rural Africa might be warranted, particularly in patients with microcytosis and those treated with zidovudine.

The porpuse of this study is to compaire anemia between diabetic and non diabetic ESRD patients. Methods. In a case control study we compared the mean valuse of Hb, Het, MCV, MCH, MCHC, BUN, Cr and duration of dialysis between diabetic and nondiabetic patients on chronic hemodialyis. some variables (such as age, sex, use of erythropoietin, nonderolone decaonats, folic acid, ferrous sulfate, transfusion and blood loss in recent three months and acquired kidney cysts were matched between cases and controls. Results. Means of Hb were 9±1.3 and 8 ± 1.7 in diabetic and non diabetic patients (P<0.05. Mean corposcular volume in diabetic patients (91±3.1 fl was more higher than non diabetic ones (87.1 ± 8.9 (P < 0.05. Other indices had no differences between two groups (P > 0.05. Discussion. Severity of anemia in patients with diabetic nephropathy is milder that other patients with ESRD. So, Anemia as an indicator of chronocity of renal disease in diabetics is missleading.
